A complex number can be written in the form \[ z = x + iy, \] where \( x, y \in \mathbb{R} \) and \( i \) is a special quantity with the property \( i^2 = -1 \). Complex numbers of the form \( iy \) are called imaginary numbers. Real numbers are also special cases of complex numbers, with y = 0.
Each complex number \( z = x + iy \) has a real part, \( Re(z) = x \), and an imaginary part, \( Im(z) = y \). Two complex numbers \( z \) and \( w \) are equal if, and only if, \( Re(z) = Re(w) \) and \( Im(z) = Im(w) \).
We also define the modulus of a complex number \( z = iy \) to be \[ |z| = \sqrt{ x^2 + y^2 }, \] which is a real, non-negative quantity.
Two complex numbers are added by seperately adding their real and imaginary parts, that is \[ z + w = (x + iy) + ( u + iv) = (x + u) + i(y + v). \]
The distributive and commutative properties (of addition and multiplication) apply to complex numbers, so it follows that multiplication is performed as \[ zw = (x + iy) (u + iv) = (xu - yv) + i(xv + yu). \]
The quotient of any two complex numbers can be found in a similar way \[ \frac{z}{w} = \frac{x + iy}{u + iv} = \frac{x + iy}{u + iv} \frac{u - iv}{u - iv} = \frac{xu + yv}{u^2 + v^2} + i \frac{yu - xv}{u^2 + v^2} \]
The complex conjugate of a complex number \( z = x + iy \) is the complex number z obtained by reversing the sign of i. Thus, \[ z^* = x - iy. \] More generally, the complex conjugate of any expression involving complex numbers is obtained by reversing the sign of i throughout the expression, or equivalently, by replacing each part of the expression by its complex conjugate. This means, for example, that \[ \left( a + \frac{bc}{d} \right) ^* = a^* + \frac{b^*c^*}{d^*}. \] Two successive sign-reversals have no net effect, so we always have \[ (z^*)^* = z. \]
Complex conjugates are useful in finding the real and imaginary parts of complex expressions. Since \[ z = Re(z) + i Im(z) \text{ and } z^* = Re(z) - i Im(z), \] we have \[ Re(z) = \frac{z + z^*}{2} \text{ and } Im(z) = \frac{z - z^*}{2i}. \]
These equations provide useful tests for whether complex expressions are real or imaginary. If an expression \( z \) is real, it has \( Im(z) = 0\), and is characterized by \( z^* = z \). By contrast, an imaginary expression has \( Re(z) = 0 \), and is characterized by \( z^* = -z \).
We also have \[ zz^* = (x + iy)(x - iy) = x^2 + y^2 = |z|^2, \] so the modulus of any complex expression \( z \) is given by \( |z| = \sqrt{zz^*} \).
In geometric terms, the complex number \( x + iy \) is represented by a point with Cartesian coordinates \( (x, y) \), and the plane consisting of all such points is called the complex plane or the Argand diagram. In this plane, the x-axis, which contains only real numbers, is called the real axis, and the y-axis, which contains only imaginary numbers, is called the imaginary axis.
The geometric relationships linking a complex number \( z = x + iy \), its complex conjugate \( z^* \), and the complex numbers \( -z \) and \( -z^* \) are shown in figure below on the left. The operations of adding and subtracting complex numbers can also be visualized geometrically. Two complex numbers \( z \) and \( w \) are represented by the points shown in figure below on the right. Their sum is represented by the point marked \( z + w \) at the corner of the blue parallelogram, while their difference is equal to the sum of \( z \) and \( -w \) and so is represented by the point marked \( z - w \) at the corner of the red parallelogram.
So far, we have specified points in the complex plane by their Cartesian coordinates \( (x, y) \), and the corresponding complex numbers written as \( x + iy \) are then said to be in Cartesian form. However, we can also specify points in the complex plane by the polar coordinates \( r \) and \( \theta \). Anticlockwise rotations increase the value of \( \theta \), while clockwise rotations decrease it. Then, values of \( \theta \) that differ by \( 2 \pi \) are equivalent in that they refer to the same point in the complex plane. We have \[ x = r cos(\theta) \text{ and } y = r sin(\theta), \] so any complex number can be written in the polar form: \[ z = r (cos(\theta) + i sin(\theta)). \]
The radial coordinate is given by \( r = \sqrt{x^2 + y^2} \), which is the modulus of the complex number. The angular coordinate \( \theta \) is called the phase, or sometimes the argument, of the complex number.
There is yet another way of expressing complex numbers, using Euler's Formula: \[ e^{i \theta} = cos(\theta) + i sin(\theta). \]Combining Euler’s formula with the polar form, we see that any complex number can be written in the form \[ z = r e^{i \theta}, \] where \( r \) is the radial coordinate (the modulus) of the complex number, and \( \theta \) is the angular coordinate (the phase). A complex number written in this way is said to be in exponential form.
Although the Cartesian form is useful for adding and subtracting complex numbers, other operations are most easily carried out using the exponential form.
To form the product of two complex numbers, we multiply their moduli andadd their phases: \[ z_1 z_2 = r_1 e^{i \theta_1} r_2 e^{i \theta_2} = r_1 r_2 e^{i \theta_1 + \theta_2}. \]
To form the complex conjugate of a complex number we keep the modulus unchanged and change the sign of the phase: \[ z^* = (r e^{i \theta})^* = r e^{-i \theta} \]
To form the quotient of two complex numbers, we divide their moduli and subtract their phases: \[ \frac{z_1}{z_2} = \frac{r_1 e^{i \theta_1}}{r_2 e^{i \theta_2}} = \frac{r_1}{r_2} e^{i (\theta_1 - \theta_2)}. \]
The figure below on the left shows the geometric effect of multiplying one complex number by another; multiplying \( w \) by \( z = r e^{i \theta} \) causes stretching by a factor of \( r \) and rotation through an angle of \( \theta \). Similarly, the figure below on the right shows the geometric effect of dividing one complex number by another; dividing by \( w \) by \( z = r e^{i \theta} \) causes stretching by a factor of \( 1/r \) and rotation through an angle of \( \theta \).
\[ z^n = (r e^{i \theta})^n = r^n e^{i n \theta} \text{, } n \in \mathbb{Z}. \]

Javascript
Arrays
- In programming, we've got to make sure that our code is well organized and structural. They can't be flung around all over the placei n a haphazard manner. This is where Arrays come into the picture. They can be used to list items.
- New Year's Resolutions:
Let’s make one here:
- Keep a journal
- Take a falconry class
- Learn to juggle
- Let’s now write this list in JavaScript, as an array:
- Here’s an array of the concepts we’ll cover:
let newYearsResolutions = ['Keep a journal', 'Take a falconry class', 'Learn to juggle'];
Arrays are JavaScript’s way of making lists. Arrays can store any data types (including strings, numbers, and booleans). Like lists, arrays are ordered, meaning each item has a numbered position.
let concepts = ['creating arrays', 'array structures', 'array manipulation']
- 1) Create an Array
- One way we can create an array is to use an array literal. An array literal makes an array by wrapping all the elements into square brackets. Recall that an array can contain any type of element within it.
- Let’s take a closer look at the syntax in the array example:
- The array is represented by the square brackets [] and the content inside.
- Each content item inside an array is called an element.
- There are three different elements inside the array.
- Each element inside the array is a different data type.
- We can also save an array to a variable. You may have noticed we did this in the previous exercise:
let newYearsResolutions = ['Keep a journal', 'Take a falconry class', 'Learn to juggle'];
- 2) Accessing Elements
- Within the topic of arrays, an interesting aspect is that arrays have self referenced tags attached to them in the sense of references.
- Within Javascript, elements within arrays are referenced from 0. Therefore, the first element will be 0 and would continue with 1 being the second element.
-
In the code snippet above:
- cities is an array that has three elements.
- We’re using bracket notation, [] with the index after the name of the array to access the element.
- cities[0] will access the element at index 0 in the array cities. You can think of cities[0] as accessing the space in memory that holds the string 'New York'.
- You can also access individual characters in a string using bracket notation and the index. For instance, you can write:
- The console will display W since it is the character that is at index 6.
const hello = 'Hello World';
console.log(hello[6]);
// Output: W
- 3)Update Elements
- Aside from accessing elements within arrays, you can update them as per your every whim.
- In the example above, the seasons array contained the names of the four seasons.
- However, we decided that we preferred to say 'Autumn' instead of 'Fall'.
- The line,
seasons[3] = 'Autumn';
tells our program to change the item at index 3 of the seasons array to be 'Autumn' instead of what is already there.
let seasons = ['Winter', 'Spring', 'Summer', 'Fall'];
seasons[3] = 'Autumn';
console.log(seasons);
//Output: ['Winter', 'Spring', 'Summer', 'Autumn']
- 4) Arrays with let and const
- Remember that we had learnt that variables declared with "let" can be reassigned but the same is not true for "const".
- However, elements in an array declared with const remain mutable. Meaning that we can change the contents of a const array, but cannot reassign a new array or a different value.
- 5) The .length property
- One of an array’s built-in properties is length and it returns the number of items in the array. We access the .length property just like we do with strings. Check the example below: const newYearsResolutions = ['Keep a journal', 'Take a falconry class']; console.log(newYearsResolutions.length); // Output: 2 In the example above, we log newYearsResolutions.length to the console using the following steps:
- We use dot notation, chaining a period with the property name to the array, to access the length property of the newYearsResolutions array.
- Then we log the length of newYearsResolution to the console. Since newYearsResolution has two elements, so 2 would be logged to the console.
- When we want to know how many elements are in an array, we can access the .length property.
-
6) The .push() Method
- We're going to learn more deeper into Javascript particularly into areas dealing with removing data and adding data into arrays.
- One method, .push() allows us to add items to the end of an array. Here is an example of how this is used:
- We access the push method by using dot notation, connecting push to itemTracker with a period.
- Then we call it like a function. That’s because .push() is a function and one that JavaScript allows us to use right on an array.
- .push() can take a single argument or multiple arguments separated by commas. In this case, we’re adding two elements: 'item 3' and 'item 4' to itemTracker.
- Notice that .push() changes, or mutates, itemTracker. You might also see .push() referred to as a destructive array method since it changes the initial array.
const itemTracker = ['item 0', 'item 1', 'item 2'];
itemTracker.push('item 3', 'item 4');
console.log(itemTracker);
// Output: ['item 0', 'item 1', 'item 2', 'item 3', 'item 4'];
So, how does .push() work?
-
7)The .pop() Method
- .pop() is another array method which removes the last item of an array. Let's consider the following example:
- In the example above, calling .pop() on the newItemTracker array removed item 2 from the end.
- .pop() does not take any arguments, it simply removes the last element of newItemTracker.
- .pop() returns the value of the last element. In the example, we store the returned value in a variable removed to be used for later.
- .pop() is a method that mutates the initial array.
- When you need to mutate an array by removing the last element, use .pop().
const newItemTracker = ['item 0', 'item
1', 'item 2'];
const removed = newItemTracker.pop();
console.log(newItemTracker);
// Output: [ 'item 0', 'item 1' ]
console.log(removed);
// Output: item 2

8)More Array Methods
- There are many more array methods than just .push() and .pop(). You can read about all of the array methods that exist on the Mozilla Developer Network (MDN) array documentation.
- .pop() and .push() mutate the array on which they’re called. However, there are times that we don’t want to mutate the original array and we can use non-mutating array methods. Be sure to check MDN to understand the behavior of the method you are using.
- Some arrays methods that are available to JavaScript developers include: .join(), .slice(), .splice(), .shift(), .unshift(), and .concat() amongst many others. Using these built-in methods make it easier to do some common tasks when working with arrays.
- The slice() method returns a shallow copy of a portion of an array into a new array object selected from begin to end (end not included) where begin and end represent the index of items in that array. The original array will not be modified.
- The unshift() method adds one or more elements to the beginning of an array and returns the new length of the array.
- The shift() method removes the first element from an array and returns that removed element. This method changes the length of the array.
Examples:
-
9) Arrays and Functions
- Throughout the lesson we went over arrays being mutable, or changeable. Well what happens if we try to change an array inside a function? Does the array keep the change after the function call or is it scoped to inside the function?
- Take a look at the following example where we call .push() on an array inside a function. Recall, the .push() method mutates, or changes, an array:
- Let’s go over what happened in the example:
- The flowers array that has 3 elements.
- The function addFlower() has a parameter of arr uses .push() to add a 'lily' element into arr.
- We call addFlower() with an argument of flowers which will execute the code inside addFlower.
- We check the value of flowers and it now includes the 'lily' element! The array was mutated!
- So when you pass an array into a function, if the array is mutated inside the function, that change will be maintained outside the function as well.
- You might also see this concept explained as pass-by-reference since what we’re actually passing the function is a reference to where the variable memory is stored and changing the memory.
const flowers = ['peony', 'daffodil', 'marigold'];
function addFlower(arr) {
arr.push('lily');
}
addFlower(flowers);
console.log(flowers);
// Output: ['peony', 'daffodil', 'marigold', 'lily']
-
10) Nested Arrays
- Nested arrays are arrays that contain elements that are enclosed in arrays themselves. Let's consider this example:
- To access the nested arrays we can use bracket notation with the index value, just like we did to access any other element:
- Notice that nestedArr[1] will grab the element in index 1 which is the array [2, 3]. Then, if we wanted to access the elements within the nested array we can chain, or add on, more bracket notation with index values.
- In the second console.log() statement, we have two bracket notations chained to nestedArr. We know that nestedArr[1] is the array [2, 3]. Then to grab the first element from that array, we use nestedArr[1][0] and we get the value of 2.
const nestedArr = [[1], [2, 3]];
const nestedArr = [[1], [2, 3]];
console.log(nestedArr[1]); // Output: [2, 3]
const nestedArr = [[1], [2, 3]];
console.log(nestedArr[1]); // Output: [2, 3]
console.log(nestedArr[1][0]); // Output: 2
- Summary
- Arrays are lists that store data in JavaScript.
- Arrays are created with brackets [].
- Each item inside of an array is at a numbered position, or index, starting at 0.
- We can access one item in an array using its index, with syntax like: myArray[0].
- We can also change an item in an array using its index, with syntax like myArray[0] = 'new string';
- Arrays have a length property, which allows you to see how many items are in an array.
- Arrays have their own methods, including .push() and .pop(), which add and remove items from an array, respectively.
- Arrays have many methods that perform different tasks, such as .slice() and .shift(), you can find documentation at the Mozilla Developer Network (MDN) array documentation website.
- Some built-in methods are mutating, meaning the method will change the array, while others are not mutating. You can always check the documentation.
- Variables that contain arrays can be declared with let or const. Even when declared with const, arrays are still mutable. However, a variable declared with const cannot be reassigned.
- Arrays mutated inside of a function will keep that change even outside the function.
- Arrays can be nested inside other arrays.
- To access elements in nested arrays chain indices using bracket notation.
In this category we've covered about arrays, as well as their influence on functions.

Fluffy is a long-haired, well-behaved kitten. Curious and spunky. Great with the elderly, children and those with olfactory limitations. Needs regular baths.
DO NOT SCARE!
Mid-sized iguana, quite tame. Loves to swim, or go for a midnight snack. Not ideal for families with small pets or children. Watch your fingers while handling ;)
Polly is a parakeet with plenty of personality. Wings are clipped, don't worry she won't fly away! Will need a large-size cage. As a bonus, scrambled a parakeet egg will feed the whole family.

The perfect accompaniment to our crunchy palak paneer . Freshly ground spices add so much flavour, so get out the pestle and mortar!
Using a pestle and mortar, pound the coriander seeds into a coarse powder. Add the cardamom pods and grind until the husks split and the seeds are lightly crushed. Add the cumin, cloves, cinnamon and bay and pound very lightly for a few seconds, to mix.
Melt half the butter in a sauté pan or wide-based saucepan over a medium heat. Fry the onion and garlic for 5 minutes, or until softened, stirring regularly. Sprinkle in the turmeric and mustard seeds, plus all the ingredients from the pestle and mortar. Fry gently for 2 minutes, stirring.
Mix in the rice to coat it in the buttery spices. Add the stock and a good pinch of black pepper. Add a pinch of salt if needed (stock from a cube will already contain salt). Stir well and bring to the boil. Give a final stir then cover the pan with a tight-fitting lid. Reduce the heat to its lowest setting and cook for 15 minutes.
When the rice is cooked, cut the rest of the butter into small pieces. Remove the pan lid and dot the butter over the hot rice. Leave to melt for a few seconds, then quickly fluff up the rice using a fork, taking care not to break up the grains.
Replace the lid and leave to stand for 5 minutes before serving. (Warn your guests not to eat the cardamom, cinnamon or any whole cloves.)

Congratulations, you've taken the first step!
Now, let's track some data.
- Use a reliable device / method to track your baseline behavior
- For example, use your fitbit or smartphone to count your daily walking steps. Or, count the number of cigarettes left in the box at the end of the day.
- Don't make changes yet, just do exactly what you would normally
- Your goal will be calculated from your baseline average. If you make changes now, intervention will be too hard!
- Submit a baseline entry for your first tracking day
- Enter the date, the total count for the behavior that day, and any important notes.
- After at least 3 baseline entries, you'll see your goal
- Your baseline average and goal will be shown, and you can begin intervention.

Tight and overtwisted contact structures
The idea of a contact structure is to attach a plane to every point of a 3-manifold in a twisty way. In particular, no surface can be everywhere tangent to the contact planes. This condition translates roughly into a non-integrability condition, so we say that a contact structure is a maximally non-integrable 2-plane distribution.
There are two kinds of contact structures: tight and overtwisted. The idea is that a tight contact structure doesn't contain any "unnecessary twisting," whereas an overtwisted one contains a disk such that, as we look at planes along radial rays, the contact planes twist all the way around (i.e., 180 degrees around).
Use the mouse to rotate. To toggle automatic rotating, click or press the space bar.
- t: Toggles visibility of the solid torus (defaults to visible)
- o: Toggles tight vs. overtwisted contact structures (defaults to tight)

Mahama calls for amendment of constitution before referendum
Former President John Mahama has called on government to urgently work to remove all hindrances that will hamper the smooth running of the December 17 referendum.
Speaking to journalists in Wa, Mr Mahama stated that it would not be useful to go for a yes vote if certain amendments are not made to the existing constitution.
“We have to repeal the part that says the President can appoint members of the District Assemblies,” he said.
“People have created the impression that we are are going to vote for DCEs to be elected. What we are being asked at the referendum is: do we want political parties to participate in the local government process?” he clarified.
The referendum has become necessary because Article 55 is an entrenched provision of the Constitution and, therefore, can only be amended after a majority yes vote.
Government wants Ghanaians to back the proposed amendment through a vote but opposition National Democratic Congress, National House of Chiefs and the Chamber for Local Governance have kicked against the move.
Speaking after a tour of some National Identification Authority’s (NIA) registration centres, he indicated that some residents complained about the slow registration pace of the Ghana Card.
The former President called on the management of the NIA to speed up the process to prevent the inconveniences faced by prospective registrants.
Meanwhile, he urged Ghanaians to take the exercise seriously since the card helps identify Ghanaians in the disbursement of social benefits.

Identiy in the age of cloud
Who is using your application and what they can do has evolved over the years. With cloud computing and the distribution of identity sources, the next iteration of this evolution is pending. A little look into the history:
<
As usual YMMV
- In the beginning was the user table (or flatfile) with a column for user name and (initially unencrypted) password. The world was good, of course only until you had enough applications and users complaint bitterly
- In the next iteration access to the network or intranet was moved to a central directory. A lot of authentication became: if (s)he can get to the server, we pick up the user name
- Other applications started to use that central directory to look up users, either via LDAP or propriety protocols. So while the password was the same, users entered it repeatedly
- Along came a flood of single sign-on frameworks, that mitigated identity information between applications, based on a central directory. Some used an adapter approach (like Tivoli Access Manager), others a standardised protocol like LTPA or SPNEGO
- All solutions are based on a carefully guarded and maintained central directory (or more than one). These directories are under full corporate control and usually defended against any attempt to alter or extend the functionality. (Some of them can't roll back schema changes and are build on fragile storage)
- Besides user identity they provide groups and sometimes roles. Often these roles are limited to directory capabilities (e.g. admin, printer-user) and applications are left to their own devices to map users/groups to roles (e.g. the ACL in IBM Notes)
- The core directory is limited to company employees and is often synchronised with a HR directory. Strategies for inclusion of customers, partners and suppliers tend to be point solutions
<
Core tenants of Identity
- An Identity Provider (IdP) is responsible to establish identity. The current standard for that is SAML, but that's not the only way. The permission delegation known as OAuth, to the confusion of many architects, can be used as authentication substitute (I allow you to read from my LinkedIn profile my name and email via OAuth and you then take that values as my identity). In any case, the cloud applications shouldn't care, they just ask the respective service "Who is this person?". Since the sources can be very different, that's all he SSO will (and shall) provide
- The next level is the basic access control. I would place that responsibility on the router, but depending on cloud capability each application needs to check itself. Depending on the security need an application might show a home page with information how to request access or deflect to an error (eventually hide behind a 404). In a micro service world an application access service could provide this information. A web UI could also use that service to render a list of available applications for the current user
- It is getting more interesting now. In classical application any action (including reading and rendering data) is linked to a user role or permission. These permissions live in code. In a cloud micro service architecture the right to action is better delegated to a rule service. This allows for more flexibility and user control. To obtain a permission a context object is handed to the rule service (XML or JSON), that in its bare minimum contains just the user identity. In more complex cases it could be value, project name, decision time etc. The rule engine then approves or denies the action
- A secondary rule service can go an lookup process information (e.g. who is the approver for a 5M loan to ACME Inc). Extracting the rules from code into a Rule Engine makes it more flexible and business accessible (You want to be good at caching)
- The rule engine or other services use a profile service to lookup user properties. This is where group memberships and roles live.
One could succumb to the temptation to let that service depend on an LDAP corporate directory, only to realise that the guardians will lock him down (again). The better approach is the profile service synchronises properties that are maintained in other systems and presents the union of them to requesting applications - So a key difference between the IdP and the profile service: the IdP has one task and one only, it performs that through lookups. The profile service provides profile information (in different combinations) that it obtained through direct entry or synchronisation
- The diagram is a high level one, the rule engine and profile service might themselves be composed of multiple micro services. This is beyond this article
As usual YMMV

LITTLE SHOP OF HORRORS (1986) A Film Review Copyright Dragan Antulov 1998
One of the saddest facts of modern Hollywood is almost total absence of musicals. Two years ago, it looked like the genre might be revived with Parker's EVITA and Woody Allen's EVERYONE SAYS I LOVE YOU. But now almost everyone can agree that the musicals are nothing but history, at least as long as Hollywood producers are concerned. The ending chapter in that bright and shining history were 1980s, with the advent of MTV and video-clip revolution. With the audience already accustomed to the three-minute videos, musicals became obsolete and too expensive form of mixing music with motion pictures. Despite that, even in such bleak times, couple of musicals shone, becoming the swan song of the genre. One of them, LITTLE SHOP OF HORRORS by Frank Oz, remains one of the most memorable viewing experiences of the previous decade.
The interesting thing about that movie is its background. The screenplay by Howard Ashman was based on his own stage play, itself based on a movie called LITTLE SHOP OF HORRORS, 1960 horror comedy by Roger Corman. The musical loosely follows the original plot, set in the seedy part of town called Skid Row.  One of them is nerdy orphan Seymour Krelborn (Rick Moranis), who dreams about his colleague, lovely shop clerk Audrey (Ellen Greene). However, he hasn't got enough courage to express his love, especially because Ellen goes out with sadistic dentist Orrin Scrivello (Steve Martin). He finds consolation in his hobby- exotic plants. One of them, named 'Audrey II', suddenly begins drawing hordes of customers to Mushnik's shop. Mushnik is happy, but not for long, because the plant begins to die. Seymour soon finds out that the only thing that can feed the plant is human blood. At first, it doesn't seem to be the problem, but as the plant grows, so do Seymour's moral dilemmas about possible plant food.
Corman's work had already earned the cult status itself and Ashman had a difficult task to match its weird quality. However, thanks to the efforts of composers Miles Goodman and Alan Menken, the play very successfully used the opportunity to turn horror comedy into musical, following the contemporary trend of 1960s nostalgia. Cinematic adaptation was given to Frank Oz, talented and experienced entertainer, who had made a reputation working on THE MUPPET SHOW. The result was splendid combination of Old Hollywood artistry with the modern 1980s sentiments.
Apart from nostalgic costumes and settings, LITTLE SHOP OF HORRORS is most recognisable by its music. Songs are original, yet very in tune with the popular trends of 1960s. Very ingenious element is the "Supremes"-like trio of three young singers, who serve as some kind of Greek chorus. Apart from that, musical numbers don't interrupt the normal plot like in most other musicals - they actually enhance it. The best example is a scene when Seymour must make a tough decision, and the song lyrics illustrates his choice.
The actors in this movie performed beautifully. Rick Moranis, short Canadian almost always typecast as nerdish sidekick, here brilliantly uses the opportunity to play main hero of the movie. His Seymour is a deeply flawed person born in poverty, and his desire for the plastic-wrapped middle class reality brings a lot of humour to his ironically tragic situation. His partner, Ellen Greene, was very experienced in playing the part of Audrey on stage, so it shouldn't surprise anyone that the cinematic version remains the best and most convincing role of her career - especially her singing of _Suddenly Seymour_ when she rejects her helium-voice, together with dumb blonde stereotypes. However, even some supporting actors have their share of glory, even in short appearances - Steve Martin as sadistic dentist, late John Candy as weird radio host, and, finally, Bill Murray as masochistic dental patient. His scene with Martin is so funny and so intense, that it should be worthy of a movie itself.
Stellar performances and catchy tunes overshadowed Frank Oz and his directorial skills. The best achievement of the movie was the creature - cannibalistic plant designed by Lyle Conway; Frank Oz gave the plant a mouth and that was enough for it to have a human traits. With the help of 40 operators and suggestive voice by Levy Stubbs, 'Audrey II' should have earned its place in the Hall of Fame for Science Fiction monsters. Unfortunately, it wasn't meant to be because the finale of the movie - Seymour's battle with 'Audrey II' - happened to be a little bit disappointing. Despite that, LITTLE SHOP OF HORRORS still remains one of the most entertaining movies of the previous decade, even for those who aren't crazy about weird musicals.

I am a(n aspiring) data scientist.

Percentage of births to females under 19
The high social and economic costs of teen pregnancy and childbearing can have short- and long-term consequences for teen parents, their children, and the community. Children of teen parents are more likely to struggle in school, be incarcerated, live in poverty, and even become teen parents themselves. Reducing rates of births to adolescents can improve future trends in health, education, and the economy. Many community factors are related to adolescents' choices and hopes for the future. Safe neighborhoods, effective schools, opportunities for structured out-of-school time activities, access to health care and health education, and employment opportunities can all influence behavior and may reduce the number of births to adolescents.
####How are we doing? The percentage of births to adolescents declined from 4.7% of all births in 2009-2010 to 3.5% of all births in 2011 and 2012. The teen birth rate in Mecklenburg County in 2013 was 24.1 per 1,000, compared to 28.4 per 1,000 in North Carolina and 29.4 per 1,000 in the United States. Despite long-term declines since 1991, teen pregnancy and birth rates remain much higher in the United States than in other developed nations, and cost U.S. taxpayers more than $9 billion each year.
####Did you know? According to the Charlotte-Mecklenburg Youth Risk Behavior Survey, 45% of high school students report ever having had sexual intercourse, and 12% report using no method of birth control to prevent pregnancy.
Number of births to females under age 19 divided by all births. These data are cumulative for the previous 24 months. Areas with fewer than 5 births are suppressed and shown as N/A.

One of the great things about Haskell is its brainy type system that allows one to enforce a variety of invariants at compile time, thereby nipping a large swathe of run-time errors in the bud. Refinement types allow us to use modern logic solvers (aka SAT and SMT engines) to dramatically extend the scope of invariants that can be statically verified.
What is a Refinement Type?
In a nutshell,
Refinement Types = Types + Logical Predicates
That is, refinement types allow us to decorate types with logical predicates (think boolean-valued Haskell expressions) which constrain the set of values described by the type, and hence allow us to specify sophisticated invariants of the underlying values.
Say what?
(Btw, click the title to demo LiquidHaskell on the code in this article)
42: module Intro where 43: 44: import Language.Haskell.Liquid.Prelude (liquidAssert)
Let us jump right in with a simple example, the number 0 :: Int
.
As far as Haskell is concerned, the number is simply an Int
(lets not
worry about things like Num
for the moment). So are 2
, 7
, and
904
. With refinements we can dress up these values so that they
stand apart. For example, consider the binder
54: zero' :: Int 55: {VV : (GHC.Types.Int) | (0 <= VV)}zero' = x:(GHC.Prim.Int#) -> {VV : (GHC.Types.Int) | (VV = (x : int))}0
We can ascribe to the variable zero'
the refinement type
61: {-@ zero' :: {v: Int | 0 <= v} @-}
which is simply the basic type Int
dressed up with a predicate.
The binder v
is called the value variable, and so the above denotes
the set of Int
values which are greater than 0
. Of course, we can
attach other predicates to the above value, for example
Note: We will use @
-marked comments to write refinement type
annotations the Haskell source file, making these types, quite literally,
machine-checked comments!
75: {-@ zero'' :: {v: Int | (0 <= v && v < 100) } @-} 76: zero'' :: Int 77: {VV : (GHC.Types.Int) | (VV < 100),(0 <= VV)}zero'' = x:(GHC.Prim.Int#) -> {VV : (GHC.Types.Int) | (VV = (x : int))}0
which states that the number is in the range 0
to 100
, or
83: {-@ zero''' :: {v: Int | ((v mod 2) = 0) } @-} 84: zero''' :: Int 85: {VV : (GHC.Types.Int) | ((VV mod 2) = 0)}zero''' = x:(GHC.Prim.Int#) -> {VV : (GHC.Types.Int) | (VV = (x : int))}0
where mod
is the modulus operator in the refinement logic. Thus, the type
above states that zero is an even number.
We can also use a singleton type that precisely describes the constant
94: {-@ zero'''' :: {v: Int | v = 0 } @-} 95: zero'''' :: Int 96: {VV : (GHC.Types.Int) | (VV = 0)}zero'''' = x:(GHC.Prim.Int#) -> {VV : (GHC.Types.Int) | (VV = (x : int))}0
(Aside: we use a different names zero'
, zero''
etc. for a silly technical
reason – LiquidHaskell requires that we ascribe a single refinement type to
a top-level name.)
Finally, we could write a single type that captures all the properties above:
106: {-@ zero :: {v: Int | ((0 <= v) && ((v mod 2) = 0) && (v < 100)) } @-} 107: zero :: Int 108: {VV : (GHC.Types.Int) | ((VV mod 2) = 0),(VV < 100),(0 <= VV)}zero = x:(GHC.Prim.Int#) -> {VV : (GHC.Types.Int) | (VV = (x : int))}0
The key points are:
- A refinement type is just a type decorated with logical predicates.
- A value can have different refinement types that describe different properties.
- If we erase the green bits (i.e. the logical predicates) we get back exactly the usual Haskell types that we know and love.
- A vanilla Haskell type, say
Int
has the trivial refinementtrue
i.e. is really{v: Int | true}
.
We have built a refinement type-based verifier called LiquidHaskell. Lets see how we can use refinement types to specify and verify interesting program invariants in LiquidHaskell.
Writing Safety Specifications
We can use refinement types to write various kinds of more interesting safety specifications.
First, we can write a wrapper around the usual error
function
133: {-@ error' :: {v: String | false } -> a @-} 134: error' :: String -> a 135: {VV : [(GHC.Types.Char)] | false} -> aerror' = [(GHC.Types.Char)] -> aerror
The interesting thing about the type signature for error'
is that the
input type has the refinement false
. That is, the function must only be
called with String
s that satisfy the predicate false
. Of course, there
are no such values. Thus, a program containing the above function
typechecks exactly when LiquidHaskell can prove that the function
error'
is never called.
Next, we can use refinements to encode arbitrary programmer-specified assertions by defining a function
149: {-@ lAssert :: {v:Bool | (Prop v)} -> a -> a @-} 150: lAssert :: Bool -> a -> a 151: {VV : (GHC.Types.Bool) | (? Prop([VV]))} -> a -> alAssert True ax = {VV : a | (VV = x)}x 152: lAssert False _ = {VV : [(GHC.Types.Char)] | false} -> {VV : a | false}error' {VV : [(GHC.Types.Char)] | (len([VV]) >= 0)}"lAssert failure"
In the refinement, (Prop v)
denotes the Haskell Bool
value v
interpreted as a logical predicate. In other words, the input type for
this function specifies that the function must only be called with
the value True
.
Refining Function Types : Preconditions
Lets use the above to write a divide function that only accepts non-zero denominators.
168: divide :: Int -> Int -> Int 169: (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV != 0)} -> (GHC.Types.Int)divide (GHC.Types.Int)n 0 = {VV : [(GHC.Types.Char)] | false} -> {VV : (GHC.Types.Int) | false}error' {VV : [(GHC.Types.Char)] | (len([VV]) >= 0)}"divide by zero" 170: divide n d = {VV : (GHC.Types.Int) | (VV = n)}n x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV = (x / y))}`div` {VV : (GHC.Types.Int) | (VV != 0)}d
We can specify that the non-zero denominator precondition with a suitable refinement on the input component of the function’s type
177: {-@ divide :: Int -> {v: Int | v != 0 } -> Int @-}
How does LiquidHaskell verify the above function?
The key step is that LiquidHaskell deduces that the expression
"divide by zero"
is not merely of type String
, but in fact
has the the refined type {v:String | false}
in the context
in which the call to error'
occurs.
LiquidHaskell arrives at this conclusion by using the fact that
in the first equation for divide
the denominator parameter
is in fact 0 :: {v: Int | v = 0}
which contradicts the
precondition (i.e. input) type.
In other words, LiquidHaskell deduces by contradiction, that
the first equation is dead code and hence error'
will
not be called at run-time.
If you are paranoid, you can put in an explicit assertion
199: divide' :: Int -> Int -> Int 200: {VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Int) | false}divide' {VV : (GHC.Types.Int) | false}n 0 = {VV : [(GHC.Types.Char)] | false} -> {VV : (GHC.Types.Int) | false}error' {VV : [(GHC.Types.Char)] | (len([VV]) >= 0)}"divide by zero" 201: divide' n d = {VV : (GHC.Types.Bool) | (? Prop([VV]))} -> {VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Int) | false}lAssert ({VV : (GHC.Types.Int) | false}d x:{VV : (GHC.Types.Int) | false} -> y:{VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x != y))}/= {VV : (GHC.Types.Int) | (VV = (0 : int))}0) ({VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Int) | false}) -> {VV : (GHC.Types.Int) | false} -> {VV : (GHC.Types.Int) | false}$ {VV : (GHC.Types.Int) | false}n x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV = (x / y))}`div` {VV : (GHC.Types.Int) | false}d
and LiquidHaskell will verify the assertion (by verifying the call to
lAssert
) for you.
Refining Function Types : Postconditions
Next, lets see how we can use refinements to describe the outputs of a function. Consider the following simple absolute value function
214: abz :: Int -> Int 215: (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz (GHC.Types.Int)n | {VV : (GHC.Types.Int) | (VV = (0 : int))}0 x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x < y))}< {VV : (GHC.Types.Int) | (VV = n)}n = {VV : (GHC.Types.Int) | (VV = n)}n 216: | otherwise = {VV : (GHC.Types.Int) | (VV = (0 : int))}0 x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV = (x - y))}- {VV : (GHC.Types.Int) | (VV = n)}n
We can use a refinement on the output type to specify that the function returns non-negative values
223: {-@ abz :: Int -> {v: Int | 0 <= v } @-}
LiquidHaskell verifies that abz
indeed enjoys the above type by
deducing that n
is trivially non-negative when 0 < n
and that in
the otherwise
case, i.e. when not (0 < n)
the value 0 - n
is
indeed non-negative (lets not worry about underflows for the moment.)
LiquidHaskell is able to automatically make these arithmetic deductions
by using an SMT solver which has decision
built-in procedures for arithmetic, to reason about the logical
refinements.
Putting It All Together
Lets wrap up this introduction with a simple truncate
function
that connects all the dots.
244: {-@ truncate :: Int -> Int -> Int @-} 245: (GHC.Types.Int) -> (GHC.Types.Int) -> (GHC.Types.Int)truncate (GHC.Types.Int)i (GHC.Types.Int)max 246: | {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i' x:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> y:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x <= y))}<= {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' = {VV : (GHC.Types.Int) | (VV = i)}i 247: | otherwise = {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (&& [(x >= 0); (y >= 0)] => (VV >= 0))}* ({VV : (GHC.Types.Int) | (VV = i)}i (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV != 0)} -> (GHC.Types.Int)`divide` {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i') 248: where {VV : (GHC.Types.Int) | (0 <= VV)}i' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = i)}i 249: {VV : (GHC.Types.Int) | (0 <= VV)}max' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = max)}max
truncate i n
simply returns i
if its absolute value is less the
upper bound max
, and otherwise truncates the value at the maximum.
LiquidHaskell verifies that the use of divide
is safe by inferring that
at the call site
i' > max'
from the branch condition.0 <= i'
from theabz
postcondition (hover mouse overi'
).0 <= max'
from theabz
postcondition (hover mouse overmax'
).
From the above, LiquidHaskell infers that i' != 0
. That is, at the
call site i' :: {v: Int | v != 0}
, thereby satisfying the
precondition for divide
and verifying that the program has no pesky
divide-by-zero errors. Again, if you really want to make sure, put
in an assertion
268: {-@ truncate' :: Int -> Int -> Int @-} 269: (GHC.Types.Int) -> (GHC.Types.Int) -> (GHC.Types.Int)truncate' (GHC.Types.Int)i (GHC.Types.Int)max 270: | {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i' x:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> y:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x <= y))}<= {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' = {VV : (GHC.Types.Int) | (VV = i)}i 271: | otherwise = {VV : (GHC.Types.Bool) | (? Prop([VV]))} -> (GHC.Types.Int) -> (GHC.Types.Int)lAssert ({VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i' x:{VV : (GHC.Types.Int) | (VV >= 0), (VV >= zero''''), (0 <= VV), (VV <= i')} -> y:{VV : (GHC.Types.Int) | (VV >= 0), (VV >= zero''''), (0 <= VV), (VV <= i')} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x != y))}/= {VV : (GHC.Types.Int) | (VV = (0 : int))}0) ((GHC.Types.Int) -> (GHC.Types.Int)) -> (GHC.Types.Int) -> (GHC.Types.Int)$ {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (&& [(x >= 0); (y >= 0)] => (VV >= 0))}* ({VV : (GHC.Types.Int) | (VV = i)}i (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV != 0)} -> (GHC.Types.Int)`divide` {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i') 272: where {VV : (GHC.Types.Int) | (0 <= VV)}i' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = i)}i 273: {VV : (GHC.Types.Int) | (0 <= VV)}max' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = max)}max
and lo! LiquidHaskell will verify it for you.
Modular Verification
Incidentally, note the import
statement at the top. Rather than rolling
our own lAssert
we can import and use a pre-defined version liquidAssert
defined in an external module
286: {-@ truncate'' :: Int -> Int -> Int @-} 287: (GHC.Types.Int) -> (GHC.Types.Int) -> (GHC.Types.Int)truncate'' (GHC.Types.Int)i (GHC.Types.Int)max 288: | {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i' x:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> y:{VV : (GHC.Types.Int) | (VV >= 0),(VV >= zero''''),(0 <= VV)} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x <= y))}<= {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' = {VV : (GHC.Types.Int) | (VV = i)}i 289: | otherwise = {VV : (GHC.Types.Bool) | (? Prop([VV]))} -> (GHC.Types.Int) -> (GHC.Types.Int)liquidAssert ({VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i' x:{VV : (GHC.Types.Int) | (VV >= 0), (VV >= zero''''), (0 <= VV), (VV <= i')} -> y:{VV : (GHC.Types.Int) | (VV >= 0), (VV >= zero''''), (0 <= VV), (VV <= i')} -> {VV : (GHC.Types.Bool) | ((? Prop([VV])) <=> (x != y))}/= {VV : (GHC.Types.Int) | (VV = (0 : int))}0) ((GHC.Types.Int) -> (GHC.Types.Int)) -> (GHC.Types.Int) -> (GHC.Types.Int)$ {VV : (GHC.Types.Int) | (VV = max'),(0 <= VV)}max' x:(GHC.Types.Int) -> y:(GHC.Types.Int) -> {VV : (GHC.Types.Int) | (&& [(x >= 0); (y >= 0)] => (VV >= 0))}* ({VV : (GHC.Types.Int) | (VV = i)}i (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (VV != 0)} -> (GHC.Types.Int)`divide` {VV : (GHC.Types.Int) | (VV = i'),(0 <= VV)}i') 290: where {VV : (GHC.Types.Int) | (0 <= VV)}i' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = i)}i 291: {VV : (GHC.Types.Int) | (0 <= VV)}max' = (GHC.Types.Int) -> {VV : (GHC.Types.Int) | (0 <= VV)}abz {VV : (GHC.Types.Int) | (VV = max)}max
In fact, LiquidHaskell comes equipped with suitable refinements for standard functions and it is easy to add refinements as we shall demonstrate in subsequent articles.
Conclusion
This concludes our quick introduction to Refinement Types and LiquidHaskell. Hopefully you have some sense of how to
- Specify fine-grained properties of values by decorating their types with logical predicates.
- Encode assertions, preconditions, and postconditions with suitable function types.
- Verify semantic properties of code by using automatic logic engines (SMT solvers) to track and establish the key relationships between program values.

All people that on earth do dwell,
Sing to the Lord with cheerful voice;
Him serve with fear, his praise forth tell.
Come ye before him and rejoice.
The Lord ye know is God indeed;
Without our aid he did us make;
We are his folk; he doth us feed,
And for his sheep he doth us take.
O enter then his gates with praise;
Approach with joy his courts unto;
Praise, laud, and bless his name always,
For it is seemly so to do.
For why? The Lord our God is good;
His mercy is forever sure;
His truth at all times firmly stood,
And shall from age to age endure.
AMEN.


I have always been obsessed with visuals. When I was a kid I would go through
my mom’s magazines, find an image I loved, check with my mom to make sure she
didn’t need the article on the back, then clip it out and safely tuck it away
in a flat, waxed-cardboard box under my bed - only to find out years later
that my mom secretly snuck in my room and downsized my collection to keep it
under control.
These days, I apply my passion for visual arts to graphic design and
photography. I soak up inspiration all around me, and still tear out magazine
ads and tuck them away for reference. I strive to visually present the facts
and discipline of science with creativity, quality, technology and whenever
possible… a bit of humor. I am always looking for new ways to approach
courses, graphics, and content to successfully visually communicate concepts
with an audience.
If I’m not behind a computer screen, you can find me outside with a camera by
my side or in mad scientist mode in my kitchen - while tripping over a hungry
cattle dog vacuum.


Tests whether nested escapability is supported.
While Media Overlays (MO) are playing within the nested magenta-bordered escapable element below, invoke the 'escape' command (assuming it is provided by the reading system), then invoke it once again from within the top-level blue-bordered escapable element.
This is a top-level escapable document fragment, identified by the epub:type="glossary"
attribute (other values should also be supported, this is for illustration purposes only).
This is another escapable document fragment, nested within the top-level one. Upon invocation of the 'escape' command in this nested element, MO playback should skip the remainder of this fragment, and continue at the next paragraph below (which is itself located within a top-level escapable fragment).
This is the remainder of the nested escapable document fragment, containing filler text to allow time to invoke the 'escape' command...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
This paragraph immediately follows the nested escapable document fragment. Upon invocation of the 'escape' command here, the remainder of this top-level escapable fragment should be skipped, and playback should continue at the "normal" paragraph down below.
This is the remainder of the top-level escapable document fragment, containing filler text to allow time to invoke the 'escape' command...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
This is a normal paragraph, immediately following the top-level escapable document fragment.
The test passes if MO playback escapes from the nested magenta-bordered escapable element, and resumes immediately after it (within yet-another escapable fragment), then escapes from the top-level blue-bordered escapable element, and resumes at the following "normal" paragraph.

"A transition to clean energy is about making an investment in our future"
Why conserve energy?
We're trying to shift our use of fuel. Forget saving energy; if we get the right kind of energy, there are endless amounts!
How our application is going to support the cause?
It predicts the accessibility of wind vitality assets and encourages the improvement in wind energy production.
What is our main motto?
Our vision is to moderate this inexhaustible wellspring of energy and thus, save the earth and construct a sustainable future.
How do we achieve it?
By this application we will predict a few qualities which are fundamental parts of bridling wind energy to its extreme.
Latest Deep learning model which uses the present value and predict the future
You can get to the application from any piece of the world and anyone can access it.
It can be accessed anytime, irrespective of your location and it is convenient to use.
It is anything but difficult to deal with and advantageously accessible. You can autofill the directions or pick any area all through the world.
Wind vitality is the most sustainable type of energy. We anticipate the eventual fate of maintainability and safeguard nature.
Sets aside less effort to foresee the fate of energy. Afterall what's quicker than foreseeing the future itself.
We are intending to make a progressively available variant of the application utilizing portable application. Stay tuned!


Data Mining allows us to extract knowledge from withing databases. Advance inference techniques are put to work in order to achieve our goal, which is the generation of knowledge to support research.
Big Data focuses on techniques and standars to manage enourmous amounts of information. Such quantities of information makes it difficult to handle by standard techniques
Ontologies gives meaning to information. By adding this, we can implement automatic reasoning in order to process information and infer knowledge from it.
Software engineering involves methodologies in order to achieve the most effcient and effective development software process.
High performance processing involves the paralelization of sequential algorithms in order to obtain results faster.
Scientific computing is the set of technologies that help us understand how our world function.

EVO HTML to PDF Converter allows you to convert a HTML to PDF in RGB color space by default but you can choose to produce the PDF document in GrayScale or CMYK color space.
In this demo you can choose between these types of color spaces when you create the PDF document.
The options you can set in this demo are:
HTML Page to Convert
-
HTML Page URL or Local File to Convert. The URL of the HTML page to convert must be accessible from the computer where the converter runs.
If the page requires authentication or if you are using a proxy server to access Internet then you have to set the converter properties accordingly
as described in documentation
Color Space
-
RGB. When this option is selected the generated PDF document will use the RGB color space
-
Gray Scale. When this option is selected the generated PDF document will use the Gray Scale color space
-
CMYK. When this option is selected the generated PDF document will use the CMYK color space


A swim ban means that swimming is not allowed. Bans may be issued due to
unsafe conditions, following a massive rain event, or extremely high e-coli levels
The U.S. EPA suggests a swim ban for e-coli counts higher than 1000 CCE. Of the
@scoreboard.daysOver1000() days in which e-coli measurements
have exceeded that, bans have only been issued
@scoreboard.percentOfDaysOver1000()% of the time.
A swim advisory means that swimmers are advised to enter with caution.
The U.S. EPA suggests a swim advisory for e-coli counts higher than 235 CCE. Of the
@scoreboard.daysOver235()
days in which e-coli levels have exceeded this level (but have been under 1000), some sort of swim
restriction has only been issued @scoreboard.percentOfDaysOver235()%
of the time.

| label_pvalue {scales} | R Documentation |
Formatter for p-values, using "<" and ">" for p-values close to 0 and 1.
label_pvalue( accuracy = 0.001, decimal.mark = ".", prefix = NULL, add_p = FALSE ) pvalue_format( accuracy = 0.001, decimal.mark = ".", prefix = NULL, add_p = FALSE ) pvalue(x, accuracy = 0.001, decimal.mark = ".", prefix = NULL, add_p = FALSE)
accuracy |
A number to round to. Use (e.g.) Applied to rescaled data. |
decimal.mark |
The character to be used to indicate the numeric decimal point. |
prefix |
A character vector of length 3 giving the prefixes to
put in front of numbers. The default values are |
add_p |
Add "p=" before the value? |
x |
A numeric vector to format. |
All label_()
functions return a "labelling" function, i.e. a function that
takes a vector x
and returns a character vector of length(x)
giving a
label for each input value.
Labelling functions are designed to be used with the labels
argument of
ggplot2 scales. The examples demonstrate their use with x scales, but
they work similarly for all scales, including those that generate legends
rather than axes.
pvalue()
and pvalue_dollar()
are retired; please use label_pvalue()
instead.
Other labels for continuous scales:
label_bytes()
,
label_dollar()
,
label_number_auto()
,
label_number_si()
,
label_ordinal()
,
label_parse()
,
label_percent()
,
label_scientific()

For some services (only S3 at the moment) you can also get API calls for data related events: e.g. file was download. Depending on your access patterns this could generate many events! Have a look at the pricing before you activate this on a public S3 bucket!
