HTML 4.01 Test Suite - Assertions
Testable Assertions: Section 17 Forms
17 Forms - User-input Forms: Text Fields, Buttons, Menus, and more
Assertion 17.2-1
(may) Control has both an initial value and a current value, both of which are character strings. the control's current value may be modified through user interaction and scripts.
Tests: None
Assertion 17.2-2
(must) A control's initial value does not change. Thus, when a form is reset, each control's current value is reset to its initial value.
Tests: None
Assertion 17.2-3
(must) When a form is submitted for processing, some controls have their name paired with their current value and these pairs are submitted with the form.
Tests: None
Assertion 17.2.1-1
(must) A user agent may support buttons. Authors may create three types of buttons with the BUTTON element or the INPUT element:
1, submit buttons: When activated, a submit button submits a form.
2. reset buttons: When activated, a reset button resets all controls to their initial values.
3. push buttons: Push buttons have no default behavior. Each push button may have client-side scripts associated with the element's event attributes.
Tests: None
Assertion 17.2.1-2
(must) A user agent must support checkboxes. Checkboxes and radio buttons are on/off switches that may be toggled by the user. A switch is "on" when the control element's checked attribute is set. When a form is submitted, only "on" checkbox controls can become successful.
Tests: None
Assertion 17.2.1-3
(must) Several checkboxes in a form may share the same control name. Thus, for example, checkboxes allow users to select several values for the same property. The INPUT element is used to create a checkbox control.
Tests: None
Assertion 17.2.1-4
(must) A user agent must support radio buttons. Radio buttons are like checkboxes except that when several share the same control name, they are mutually exclusive. When one is switched "on", all others with the same name are switched "off". The INPUT element is used to create a radio button control. If no radio button in a set sharing the same control name is initially "on", user agent behavior for choosing which control is initially "on" is undefined.
Tests: None
Assertion 17.2.1-5
(must) A user agent must suport menus. Menus offer users options from which to choose. The SELECT element creates a menu, in combination with the OPTGROUP and OPTION elements.
Tests: None
Assertion 17.2.1-6
(must) A user agent must support text input. Authors may create two types of controls that allow users to input text. The INPUT element creates a single-line input control and the TEXTAREA element creates a multi-line input control. In both cases, the input text becomes the control's current value.
Tests: None
Assertion 17.2.1-7
(must) A user agent must support file select. This control type allows the user to select files so that their contents may be submitted with a form. The INPUT element is used to create a file select control.
Tests: None
Assertion 17.2.1-8
(must) A user agent must support hidden control. This control type allows the user to select files so that their contents may be submitted with a form. The INPUT element is used to create file select control.
Tests: None
Assertion 17.2.1-9
(must) A user agent must support object control. Authors may insert generic objects in forms such that associated values are submitted along with other controls. Authors create object controls with the OBJECT element.
Tests: None
Assertion 17.3-1
(author)(must) FORM: Start tag: required, End tag: required.
Tests: None
Assertion 17.3-2
(must) FORM:action = uri [CT]
This attribute specifies a form processing agent. User agent behavior for a value other than an HTTP URI is undefined.
Tests: None
Assertion 17.3-3
(must) FORM:method = get|post [CI]
This attribute specifies which HTTP method will be used to submit the form data set. Possible (case-insensitive) values are "get" (the default) and "post".
Tests: None
Assertion 17.3-4
(must) FORM:enctype = content-type [CI]
This attribute specifies the content type used to submit the form to the server (when the value of method is "post"). The default value for this attribute is "application/x-www-form-urlencoded". The value "multipart/form-data" should be used in combination with the INPUT element, type="file".
Tests: None
Assertion 17.3-5
(must) FORM:accept-charset = charset list [CI]
This attribute specifies the list of character encodings for input data that is accepted by the server processing this form. The value is a space- and/or comma-delimited list of charset values.
Tests: None
Assertion 17.3-6
(must) FORM:accept = content-type-list [CI]
This attribute specifies a comma-separated list of content types that a server processing this form will handle correctly. User agents may use this information to filter out non-conforming files when prompting a user to select files to be sent to the server.
Tests: None
Assertion 17.3-7
(must) FORM:name = cdata [CI]
This attribute names the element so that it may be referred to from style sheets or scripts.
Tests: None
Assertion 17.3-8
(must) The FORM element acts as a container for controls. It specifies:
1. The layout of the form (given by the contents of the element).
2. The program that will handle the completed and submitted form (the action attribute). The receiving program must be able to parse name/value pairs in order to make use of them.
3. The method by which user data will be sent to the server (the method attribute).
4. A character encoding that must be accepted by the server in order to handle this form (the accept-charset attribute).
Tests: None
Assertion 17.4-1
(author)(must) INPUT: Start tag: required, End tag: forbidden
Tests: None
Assertion 17.4-2

Assertion 17.4-3
(must) INPUT:name = cdata [CI]
This attribute assigns the control name.
Tests: None
Assertion 17.4-4
(must) INPUT:value = cdata [CA]
This attribute specifies the initial value of the control. It is optional except when the type attribute has the value "radio" or "checkbox".
Tests: None
Assertion 17.4-5
(must) INPUT:size = cdata [CN]
This attribute tells the user agent the initial width of the control. The width is given in pixels except when type attribute has the value "text" or "password". In that case, its value refers to the (integer) number of characters.
Tests: None
Assertion 17.4-6
(must) INPUT:maxlength = number [CN]
When the type attribute has the value "text" or "password", this attribute specifies the maximum number of characters the user may enter. This number may exceed the specified size, in which case the user agent should offer a scrolling mechanism. The default value for this attribute is an unlimited number.
Tests: None
Assertion 17.4-7
(must) INPUT:checked [CI]
When the type attribute has the value "radio" or "checkbox", this boolean attribute specifies that the button is on. User agents must ignore this attribute for other control types.

Assertion 17.4.1-1
(must) INPUT type = text
Creates a single-line text input control.
Tests: None
Assertion 17.4.1-2

Creates a submit button.
Tests: None
Assertion 17.4.1-6
(must) INPUT type = image
Creates a graphical submit button. The value of the src attribute specifies the URI of the image that will decorate the button. For accessibility reasons, authors should provide alternate text for the image via the alt attribute.
When a pointing device is used to click on the image, the form is submitted and the click coordinates passed to the server. The x value is measured in pixels from the left of the image, and the y value in pixels from the top of the image. The submitted data includes name.x=x-value and name.y=y-value where "name" is the value of the name attribute, and x-value and y-value are the x and y coordinate values, respectively.
Tests: None
Assertion 17.4.1-7
(must) INPUT type = reset
Creates a reset button.
Tests: None
Assertion 17.4.1-8

Assertion 17.5-1
(must) BUTTON: Start tag: required, End tag: required.
Tests: None
Assertion 17.5-2
(must) BUTTON:name = cdata [CI]
This attribute assigns the control name.

This attribute declares the type of the button. Possible values:
1. submit: Creates a submit button. This is the default value.
2. reset: Creates a reset button.
3. button: Creates a push button.
Tests: None
Assertion 17.5-6
(may) Visual user agents may render BUTTON buttons with relief and an up/down motion when clicked, while they may render INPUT buttons as "flat" images.
Tests: None
Assertion 17.6-1
(author)(must) SELECT: Start tag: required, End tag: required
Tests: None
Assertion 17.6-2
(must) SELECT:name = cdata [CI]
This attribute assigns the control name.
Tests: None
Assertion 17.6-3
(must) SELECT:size = number [CN]
If a SELECT element is presented as a scrolled list box, this attribute specifies the number of rows in the list that should be visible at the same time.
Assertion 17.6-4
(must) SELECT:multiple [CI]
If set, this boolean attribute allows multiple selections. If not set, the SELECT element only permits single selections.
Tests: None
Assertion 17.6-5
(must) The SELECT element creates a menu. Each choice offered by the menu is represented by an OPTION element. A SELECT element must contain at least one OPTION element. The OPTGROUP element allows authors to group choices logically.
Tests: None
Assertion 17.6.1-1
(must) Zero or more choices may be pre-selected for the user. User agents should determine which choices are pre-selected as follows:
1. If no OPTION element has the selected attribute set, user agent behavior for choosing which option is initially selected is undefined. The initial state has the first option selected, unless a SELECTED attribute is present on any of the OPTION elements.
2. If one OPTION element has the selected attribute set, it should be pre-selected.
3. If the SELECT element has the multiple attribute set and more than one OPTION element has the selected attribute set, they should all be pre-selected.
4. It is considered an error if more than one OPTION element has the selected attribute set and the SELECT element does not have the multiple attribute set. User agents may vary in how they handle this error, but should not pre-select more than one choice.
Assertion 17.6.1-2
(author)(must) OPTGROUP: Start tag: required, End tag: required
Tests: None
Assertion 17.6.1-3
(must) OPTGROUP:label = text [CS]
This attribute specifies the label for the option group.
Tests: None
Assertion 17.6.1-4
(author)(must) OPTION: Start tag: required, End tag: optional
Tests: None
Assertion 17.6.1-5
(must) OPTION:selected [CI]
When set, this boolean attribute specifies that this option is pre-selected.
Tests: None
Assertion 17.6.1-6
(must) OPTION:value = cdata [CS]
This attribute specifies the initial value of the control. If this attribute is not set, the initial value is set to the contents of the OPTION element.
Tests: None
Assertion 17.6.1-7
(must) OPTION:label = text [CS]
This attribute allows authors to specify a shorter label for an option than the content of the OPTION element. When specified, user agents should use the value of this attribute rather than the content of the OPTION element as the option label.
Tests: None
Assertion 17.6.1-8
(should) When rendering a menu choice, user agents should use the value of the label attribute of the OPTION element as the choice. If this attribute is not specified, user agents should use the contents of the OPTION element.
Tests: None
Assertion 17.7-1
(author)(must) TEXTAREA: Start tag: required, End tag: required
Tests: None
Assertion 17.7-2
(must) TEXTAREA:name = cdata [CI]
This attribute assigns the control name.
Tests: None
Assertion 17.7-3
(must) TEXTAREA:rows = number [CN]
This attribute specifies the number of visible text lines.
Assertion 17.7-4
(must) TEXTAREA:cols = number [CN]
This attribute specifies the visible width in average character widths.
Assertion 17.7-5
(should) The TEXTAREA element creates a multi-line text input control. User agents should use the contents of this element as the initial value of the control and should render this text initially.
Tests: None
Assertion 17.8-1
(must)(deprecated) ISINDEX is deprecated. This element creates a single-line text input control. Authors should use the INPUT element to create text input controls.
Tests: None
Assertion 17.8-2
(must)(deprecated) ISINDEX: prompt = text [CS]. This attribute specifies a prompt string for the input field.
Tests: None
Assertion 17.9-1
(should) Some form controls automatically have labels associated with them (press buttons) while most do not (text fields, checkboxes and radio buttons, and menus).For those controls that have implicit labels, user agents should use the value of the value attribute as the label string. The LABEL element is used to specify labels for controls that do not have implicit labels.
Tests: None
Assertion 17.9.1-1
(author)(must) LABEL: Start tag: required, End tag: required
Tests: None
Assertion 17.9.1-2
(must) LABEL:for = idref [CS]
This attribute explicitly associates the label being defined with another control. When present, the value of this attribute must be the same as the value of the id attribute of some other control in the same document. When absent, the label being defined is associated with the element's contents.
Tests: None
Assertion 17.9.1-3
(must) Each LABEL element is associated with exactly one form control. The for attribute associates a label with another control explicitly: the value of the for attribute must be the same as the value of the id attribute of the associated control element. More than one LABEL may be associated with the same control by creating multiple references via the for attribute.
Tests: None
Assertion 17.9.1-4
(must) To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element. The label itself may be positioned before or after the associated control.
Tests: None
Assertion 17.9.1-5
(must) When a LABEL element receives focus, it passes the focus on to its associated control
Tests: None
Assertion 17.10-1
(author)(must) FIELDSET and LEGEND: The start tag and end tag are required.
Tests: None
Assertion 17.10-2
(must)(deprecated) LEGEND:align = top|bottom|left|right [CI]

Tests: None
Assertion 17.11-1
(must) In an HTML document, an element must receive focus from the user in order to become active and perform its tasks.
Tests: None
Assertion 17.11.1-1
(must) CONTROL:tabindex = number [CN]
This attribute specifies the position of the current element in the tabbing order for the current document. This value must be a number between 0 and 32767. User agents should ignore leading zeros.
Assertion 17.11.1-2
(should) Elements that may receive focus should be navigated by user agents according to the following rules:
1. Those elements that support the tabindex attribute and assign a positive value to it are navigated first. Navigation proceeds from the element with the lowest tabindex value to the element with the highest value. Values need not be sequential nor must they begin with any particular value. Elements that have identical tabindex values should be navigated in the order they appear in the character stream.
2. Those elements that do not support the tabindex attribute or support it and assign it a value of "0" are navigated next. These elements are navigated in the order they appear in the character stream.
3. Elements that are disabled do not participate in the tabbing order.
Tests: None
Assertion 17.11.1-3
(must) The following elements support the tabindex attribute: A, AREA, BUTTON, INPUT, OBJECT, SELECT, and TEXTAREA.
Tests: None
Assertion 17.11.2-1
(must) CONTROL:accesskey = character [CN]
This attribute assigns an access key to an element. An access key is a single character from the document character set.
Tests: None
Assertion 17.11.2-2
(must) Pressing an access key assigned to an element gives focus to the element. The following elements support the accesskey attribute: A, AREA, BUTTON, INPUT, LABEL, and LEGEND, and TEXTAREA.
Tests: None
Assertion 17.12-1
(should) In contexts where user input is either undesirable or irrelevant, it is important to be able to disable a control or render it read-only.
Tests: None
Assertion 17.12.1-1
(must) CONTROL:disabled [CI]
When set for a form control, this boolean attribute disables the control for user input.
Assertion 17.12.1-2
(should) When set, the disabled attribute has the following effects on an element:
1. Disabled controls do not receive focus.
2. Disabled controls are skipped in tabbing navigation.
3. Disabled controls cannot be successful.
Tests: None
Assertion 17.12.1-3
(must) The following elements support the disabled attribute: BUTTON, INPUT, OPTGROUP, OPTION, SELECT, and TEXTAREA.
Tests: None
Assertion 17.12.1-4
(must) The only way to modify dynamically the value of the disabled attribute is through a script.
Tests: None
Assertion 17.12.2-1
(must) CONTROL:readonly [CI]
When set for a form control, this boolean attribute prohibits changes to the control.
Tests: None
Assertion 17.12.2-2
(must) When set, the readonly attribute has the following effects on an element:
1. Read-only elements receive focus but cannot be modified by the user.
2. Read-only elements are included in tabbing navigation.
3. Read-only elements may be successful.
Tests: None
Assertion 17.12.2-3
(must) The following elements support the readonly attribute: INPUT and TEXTAREA.
Tests: None
Assertion 17.12.2-4
(must) The only way to modify dynamically the value of the readonly attribute is through a script.
Tests: None
Assertion 17.13.1-1
(author)(should) The method attribute of the FORM element specifies the HTTP method used to send the form to the processing agent. This attribute may take two values: "get" and "post". The "get" method should be used when the form is idempotent (i.e., causes no side-effects). Otherwise "post" method should be used.
Tests: None
Assertion 17.13.2-1
(may) A successful control is "valid" for submission. Every successful control has its control name paired with its current value as part of the submitted form data set. A successful control must be defined within a FORM element and must have a control name.
However:
1. Controls that are disabled cannot be successful.
2. If a form contains more than one submit button, only the activated submit button is successful.
3. All "on" checkboxes may be successful.
4. For radio buttons that share the same value of the name attribute, only the "on" radio button may be successful.
5. For menus, the control name is provided by a SELECT element and values are provided by OPTION elements. Only selected options may be successful. When no options are selected, the control is not successful.
6. The current value of a file select is a list of one or more file names. Upon submission of the form, the contents of each file are submitted with the rest of the form data. The file contents are packaged according to the form's content type.
7. The current value of an object control is determined by the object's implementation.
Tests: None
Assertion 17.13.2-2
(must) If a control doesn't have a current value when the form is submitted, user agents are not required to treat it as a successful control.
Tests: None
Assertion 17.13.2-3
(must) User agents should not consider the following controls successful:
1. Reset buttons.
2. OBJECT elements whose declare attribute has been set.
Tests: None
Assertion 17.13.2-4
(must) Hidden controls such as "password" will still cause a value to be paired with the name "invisible-password" and submitted with the form.
Tests: None
Assertion 17.13.3-1
(must) When the user submits a form (e.g., by activating a submit button), the user agent processes it as follows.
1. Identify the successful controls
2. Build a form data set(a form data set is a sequence of control-name/current- value pairs constructed from successful controls)
3: Encode the form data set (The form data set is then encoded according to the content type specified by the enctype attribute of the FORM element).
4. Step four: Submit the encoded form data set .
5. The encoded data is sent to the processing agent designated by the action attribute using the protocol specified by the method attribute
Tests: None
Assertion 17.13.4-1
(must) Forms submitted with content type application/x-www-form-urlencoded must be encoded as follows:
1. Control names and values are escaped. Space characters are replaced by `+', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., `%0D%0A').
2. The control names/values are listed in the order they appear in the document. The name is separated from the value by `=' and name/value pairs are separated from each other by `&'.
Tests: None
Assertion 17.13.4-2
(must) Forms submitted with content type "multipart/form-data must be encoded as follows:
1. User agents should supply the "Content-Type" header whose value is "multipart/form-data".
2. a "Content-Disposition" header whose value is "form-data" and a name attribute specifying the control name of the corresponding control. The file name may be specified with the "filename" parameter.
3. Each part may be encoded and the "Content-Transfer-Encoding" header supplied if the value of that part does not conform to the default (7BIT) encoding (see [RFC2045], section 6)
4. If the contents of a file are submitted with a form, the file input should be identified by the appropriate content type (e.g., "application/octet-stream").
5. If multiple files are to be returned as the result of a single form entry, they should be returned as "multipart/mixed" embedded within the "multipart/form-data".

Description
The map is created using Leaflet, a super mapping library for JavaScript. After the data is plotted all the number crunching is done using TurfJS, an extension to Leaflet developed by MapBox. All of this work is done client-side which means there's zero horsepower being used on your server outside of serving up static content resources. The data is served up as GeoJSON data which is easily digested by Turf. The map itself is served up by OpenStreetMap by way of MapBox.

Sebastian Raschka, last updated: 05/14/2015
Majority Rule Ensemble Classifier
from mlxtend.sklearn import EnsembleClassifier
And ensemble classifier that predicts class labels based on a majority voting rule (hard voting) or average predicted probabilities (soft voting).
Decision regions plotted for 4 different classifiers:
Please see the IPython Notebook for a detailed explanation and examples.
The EnsembleClassifier
will likely be included in the scikit-learn library as VotingClassifier
at some point, and during this implementation process, the EnsembleClassifier
has been slightly improved based on valuable feedback from the scikit-learn community.
Cross-validation Example
Input:
from mlxtend.sklearn import EnsembleClassifier
from sklearn import cross_validation
from sklearn.linear_model import LogisticRegression
from sklearn.naive_bayes import GaussianNB
from sklearn.ensemble import RandomForestClassifier
import numpy as np
from sklearn import datasets
iris = datasets.load_iris()
X, y = iris.data[:, 1:3], iris.target
np.random.seed(123)
################################
# Initialize classifiers
################################
clf1 = LogisticRegression()
clf2 = RandomForestClassifier()
clf3 = GaussianNB()
################################
# Initialize EnsembleClassifier
################################
# hard voting
eclf = EnsembleClassifier(clfs=[clf1, clf2, clf3], voting='hard')
# soft voting (uniform weights)
# eclf = EnsembleClassifier(clfs=[clf1, clf2, clf3], voting='soft')
# soft voting with different weights
# eclf = EnsembleClassifier(clfs=[clf1, clf2, clf3], voting='soft', weights=[1,2,10])
################################
# 5-fold Cross-Validation
################################
for clf, label in zip([clf1, clf2, clf3, eclf], ['Logistic Regression', 'Random Forest', 'naive Bayes', 'Ensemble']):
scores = cross_validation.cross_val_score(clf, X, y, cv=5, scoring='accuracy')
print("Accuracy: %0.2f (+/- %0.2f) [%s]" % (scores.mean(), scores.std(), label))
Output:
Accuracy: 0.90 (+/- 0.05) [Logistic Regression]
Accuracy: 0.92 (+/- 0.05) [Random Forest]
Accuracy: 0.91 (+/- 0.04) [naive Bayes]
Accuracy: 0.95 (+/- 0.05) [Ensemble]
GridSearch Example
The EnsembleClassifier
van also be used in combination with scikit-learns gridsearch module:
from sklearn.grid_search import GridSearchCV
clf1 = LogisticRegression(random_state=1)
clf2 = RandomForestClassifier(random_state=1)
clf3 = GaussianNB()
eclf = EnsembleClassifier(clfs=[clf1, clf2, clf3], voting='soft')
params = {'logisticregression__C': [1.0, 100.0],
'randomforestclassifier__n_estimators': [20, 200],}
grid = GridSearchCV(estimator=eclf, param_grid=params, cv=5)
grid.fit(iris.data, iris.target)
for params, mean_score, scores in grid.grid_scores_:
print("%0.3f (+/-%0.03f) for %r"
% (mean_score, scores.std() / 2, params))

Graph2d | Groups Example
This example shows the groups functionality within Graph2d. This works in the same way as it does in Timeline,
We have however simplified the constructor to accept groups as well to shorten the code. These groups are the
method used in Graph2d to define individual graphs. These groups can be given an individual class as well as all the
styling options you can supply to Graph2d! This example, as well as the ones that follow will showcase a few different usages
of these options.
This example also introduces the automatically generated legend. The icons are automatically generated and the label is the
content as you define it in the groups. If you have datapoints that are not part of a group, a default group is created with the label: 'default'.
In this example, the setting defaultGroup
is used to rename the default group to 'ungrouped'.


I am Programmer
I am an engineering student.I am a web developer . I have very much interest in software work . Want to learn much more things in this field.
I started programming from 1st year of engineering as I was not much familier with programming .But now under the guidance of my collegues and friend I have learn many things in the programming world in a very short period of time. I came to know that I am a quick learner.
 During coding I always get hungry and after that I always use to go for break to have a french fries outside.I know its not good for health but I am trying to eat it in control.
Lets code together while eating french fries .

Thermal Modeling (June 2004)¶
Overview¶
The thermal Finite Element Method (FEM) models should be used to evaluate the soft tissue heating that occurs in soft tissue due to absorption of ultrasonic energy during ARFI imaging. There are two publications regarding thermal response of tissues during ARFI imaging that should be read before doing thermal modeling and measurements .
The models allow the user to input transducer specific parameters, such as focal depth, F/#, element dimensions, etc. Depending on the focal depth that is specified, a pre-made mesh is selected, and Field II is run to solve for the intensity fields generated by the transducer. These intensity fields are scaled by emperically-determined \(I_{spta}\) values, and then LS-DYNA is used to solve for the heating and cooling behavior in tissue, using user-specified material properties. The results are compared with thermocouple measurements in porcine muslce, and then thermal-convolution scripts are run in MATLAB to solve for the heating associated with different beam spacings, fields-of-view, and focal depths.
Front End¶
[This still needs to be written (PERL).]
FEM Meshes¶
The meshes used for the models need to be as small as possible, in terms of node counts and number of elements, to reduce computation overhead and disk usage. When modeling, low-freqeuncy transducer at deep docal depths, larger meshes are necessary. This document will be written with the VF10-5, and it’s assocaited mesh, in mind.
Generic meshes are saved as XDCRmaxfocdepth.dyn (e.g., VF105foc25mm.dyn). These meshes are LS-DYNA input deck templates that contain input for the FEM runs, including the node/element information. Field II will be used to solve for the intesities at these nodal locations (calc_hp). This information is read into MATLAB using read_dyna_nodes.m, which saves a variable measurementPointsandNodes that contains the node IDs, along with the x, y, and z coordinates respectively.
New meshes will need to be generated if you have a transducer that will need to go deeper than one of the current meshes allows or if the transducer has a doemetry that doesn’t conform to a pre-existing mesh. HyperMesh is a Windows-based program that can be used to generate meshes that can be exported for use in LS-DYNA. Documentation and tutorials for how to use HyperMesh, along with tutorial exercises can be found in /data/jlb/src/altair/6.0/docs/ . Doug Dumont has also written a nice tutorial on how to use HyperMesh (HyperMesh.pdf).
Field II¶
Field II is called from within the front end PERL script to solve to the intensity values at each nodal location for each focal configuration and material attenuation. [The old scripts used to do this are field2dyna.m and fieldprms3d_arfi.m .] The results are saved into MATLAB files called dyna_isptaout_att??.mat, which include the measurementPointsandNodes variable, along with an isptaout variable that has node intensity values for select nodes in the mesh where ultrasonic energy is absorbed.
Intensity Measurements¶
The intensity fields that are simulated by Field II need to be scaled up to values that will be used in vivo. This is accomplished by performing a linear extrapolation of the of small-signal derated intensity fields, as outlined in the 2002 NCRP report . First, intensity measurements are made using a hydrophone in a water tank at low power values to avoid saturation of the water. [CITE DOCUMENTATION ON MAKING HYDROPHONE MEASUREMENTS]
Thermocouple Measurements¶
See Kristin Frinkley’s document on making thermocouple measurements (tcprotocol.pdf).
LS-DYNA¶
LS-DYNA is a non-linear, three-dimensional, finite element analysis program that is used for structural and thermal modeling in the lab. Documentation for running models in LS-DYNA can be found in /data/jlb/src/lstc/docs/. Details on the types of elements used in the models are included in the first thermal publications .
Once the intesity values from Field II are scale appropraitely using the hydrophone and thermocouple measurements, these values must be converted to heat sources to modeling the heating behavior or the tissue, or to initial temperatures to model the cooling of the tissue. We will start with the later case.
As outlined in the first thermal publication , when heat is applied over a short time period relative to the thermal conductivity of the materal, the temperature increase can be solved using Equation [inittemp]:
\(I\) in Equation [inittemp] is the scaled intensity value that was determined in the earlier sections of this document. By inputing initial temperatures, the FEA can be performed with cruder time steps for cooling response. These initial temperatures are determined using the MATLAB script make_asc_therm.m, which saves the file inittemps.asc, which has column data of the form: node ID, initial temp (deg C). This file is then read in as an initial condition into the LS-DYNA input deck under the card INITIAL_TEMPERATURE_NODE.
Heat sources will need to be generated when the high-intesity ARFI pushing pulses are applied over a greater time duration relative to the thermal conductivity. If you are in doubt, generate the heat sources and run the simulation. [NEED TO ADD ALL OF THIS]
MATLAB Output¶
LS-DYNA saves its results in d3plot files. To perform post-processing on these results in MATLAB, these results are converted to MATLAB format using the function d3plotConvert.m . This function reads in the header of the binary d3plot file, and creates variables of the relevant data, which in this case is nodal temperature data through time. This data is saved to dyna_convolve_FR.mat and dyna_convolve_FR_elev.mat, which contain the temperature data on the two symmetry faces (axial-lateral, and axial-elevation respectively) through time. All other data in the d3plot files is not saved to the MATLAB result files - if this data is needed, it can be viewed using ls-prepost or saved separated in MATLAB.
Thermal Convolution¶
The FEM analyzes the heating and cooling associated with a single ARFI interrogation. To simulate the heating and cooling assocaited with multiple lines per frame, and multiple frames of ARFI imaging, convulation of the thermal results is performed in MATLAB using convolveFR.m [THIS MIGHT CHANGE - NEED TO ADD LOTS OF COMMENTS TO CODE ON HOW THIS WORKS - THE INVLUDE THAT CODE (VERBATIM) HERE]

Detailed Description
The QLCDNumber widget displays a number with LCD-like digits.
It can display a number in just about any size. It can display decimal, hexadecimal, octal or binary numbers. It is easy to connect to data sources using the display() slot, which is overloaded to take any of five argument types.
There are also slots to change the base with setMode() and the decimal point with setSmallDecimalPoint().
QLCDNumber emits the overflow() signal when it is asked to display something beyond its range. The range is set by setDigitCount(), but setSmallDecimalPoint() also influences it. If the display is set to hexadecimal, octal or binary, the integer equivalent of the value is displayed.
These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S, 6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o, P, r, u, U, Y, colon, degree sign (which is specified as single quote in the string) and space. QLCDNumber substitutes spaces for illegal characters.
It is not possible to retrieve the contents of a QLCDNumber object, although you can retrieve the numeric value with value(). If you really need the text, we recommend that you connect the signals that feed the display() slot to another slot as well and store the value there.
Incidentally, QLCDNumber is the very oldest part of Qt, tracing its roots back to a BASIC program on the Sinclair Spectrum.
See also QLabel, QFrame, Digital Clock Example, and Tetrix Example.

Cleanup for sequential highlight slideshow
- Select keyframe
Need cleanup!: Extract foreground: constant threshold does not work well across keyframes / nor across lectures
e.g. threshold = 225 works well for Khan, but not for Armando. Currently, I am manually selecting threshold parameter.
Instead using threshold = 0.8 * mean_luminance_of_keyframes_in_this_lecture works well across lectures.
e.g. Heart, Khan, MIT, Udacity
- Removing mouse pointers and hands:
- Logos are easy since they are fixed, don't cover other images
- Need cleanup!: But in case of cursors, need to leave rest of the board image
e.g. Image is missing in the right region after whiting-out mouse cursor
- Need cleanup!: Or selecting keyframes w/o hand or cursor
- Need cleanup!: Identify redundant parts keyframe image:
- SIFT feature + BruteForce matcher
- Template matching
This part is not robust yet. There are parameters controlling - switching between template matching versus sift feature matching
- sift feature threshold
- good match vs bad match to discard
- Discard keyframe without any new part / Only highlight new parts in each keyframe
- Need cleanup!: Automatically generated transcripts

Zika virus (ZIKV) is a mosquito-borne flavivirus distributed throughout much of Africa and Asia. Infection with the virus may cause acute febrile illness that clinically resembles dengue fever. A recent study indicated the existence of three geographically distinct viral lineages; however this analysis utilized only a single viral gene. Although ZIKV has been known to circulate in both Africa and Asia since at least the 1950s, little is known about the genetic relationships between geographically distinct virus strains. Moreover, the geographic origin of the strains responsible for the epidemic that occurred on Yap Island, Federated States of Micronesia in 2007, and a 2010 pediatric case in Cambodia, has not been determined.
To elucidate the genetic relationships of geographically distinct ZIKV strains and the origin of the strains responsible for the 2007 outbreak on Yap Island and a 2010 Cambodian pediatric case of ZIKV infection, the nucleotide sequences of the open reading frame of five isolates from Cambodia, Malaysia, Nigeria, Uganda, and Senegal collected between 1947 and 2010 were determined. Phylogenetic analyses of these and previously published ZIKV sequences revealed the existence of two main virus lineages (African and Asian) and that the strain responsible for the Yap epidemic and the Cambodian case most likely originated in Southeast Asia. Examination of the nucleotide and amino acid sequence alignments revealed the loss of a potential glycosylation site in some of the virus strains, which may correlate with the passage history of the virus.
The basal position of the ZIKV strain isolated in Malaysia in 1966 suggests that the recent outbreak in Micronesia was initiated by a strain from Southeast Asia. Because ZIKV infection in humans produces an illness clinically similar to dengue fever and many other tropical infectious diseases, it is likely greatly misdiagnosed and underreported.

Phase 2: Temperature monitoring logged on webserver.
[sourcecode language="c"]
/*
Web Server
A simple web server that shows the temperature using an Arduino Wiznet Ethernet shield.
Parts list:
10k Thermistor
Breadboard/Veroboard
10k resistor
Arduino ( I use UNO)
Arduino Wiznet Ethernet shield
The Thermistor Circuit:
AREF---+3.3V----Therm----A0(Arduino)----10k res---> Gnd
Better Readings:
When doing analog readings, especially with a 'noisy' board like the arduino, we suggest two tricks to improve results.
One is to use the 3.3V voltage pin as an analog reference and the other is to take a bunch of readings in a row and average them.
The first trick relies on the fact that the 5V power supply that comes straight from your computer's USB does a lot of stuff on the Arduino,
and is almost always much noisier than the 3.3V line (which goes through a secondary filter/regulator stage!) It's easy to use, simply connect 3.3V to AREF and use that as the VCC voltage.
Because our calcuations don't include the VCC voltage, you don't have to change your equation. You do have to set the analog reference but that's a single line of code
Taking multiple readings to average out the result helps get slightly better results as well, since you may have noise or fluctuations, we suggest about 5 samples.

Thank you for your recent note about my new site at Sage Advice.
Exon Inspiration is merely interactive art applied to the free market.
If people do not wish to go there, they don't have to.
As for the body parts, I thought that was rather a neat statement
summarizing the raw elemental nature of sex from the point of
view of the id.
Thanks also for your offer of employment. I like the job I have.
Lee
I groan inwardly. This is going to be a nasty one, no doubt about it. There is nothing more intransigent than an artist defending art for the sake of freedom of expression; nothing more dangerous, unless one gets between a baby hippopotamus and its mother.
Yet there is no point hiding or even wasting time. I learned long ago that crafting a response for e-mail is a waste of time. On the Net one has to speak one's mind, speak one's heart, and let the truth prevail. If truth can be found.

RE: Wherefore art?
Lee:
Art speaks to the human condition, and, more than technology, is our
last and best hope for progress.
The hallmark of civilization is that while we recognize our capacity
for evil, we nevertheless renounce it and work towards a better future.
Your site graphically portrays sadism, rape, torture, and murder. Okay,
others have done so in other media before you. Because your site
is interactive, however, it enlists the participation of others to engage,
even if only conceptually, in such cruelties. By charging fees to
others for participating, you thereby assign value to dehumanization.
And you make no attempt to renounce the evil you display.
In the arena of the spirit, silence is consent.
In short, I believe that you have moved beyond art into exploitation
for profit. This is not a good thing.
Respectfully,
First Citizen
I barely sit down to enjoy my first cup of coffee of the day, a good, strong French Roast, when Lee replies. S/he must be staying up late at the keyboard. I am delighted. The more e-mail I can get from Lee, the more chance I have of obtaining something that I can use. In the world of infodemocracy, discourse is water. It makes life possible. S/he replies:
[snip]
But that's the point. Don't you see? You talk about
'evil' and 'good' as if these were objective criteria.
But they're not. You have to let people decide for
themselves what constitutes 'good' and 'evil'.
Lee
I can feel the coffee churning in my stomach. This is really going to be a tough one. If Lee had told me, in good Australian fashion, to go piss off, I would be happier. Instead, I've stepped into an oozing black tar pit of moral relativism; Ethics 101.
At any rate, s/he has given me the wedge I need.

Combined Grid Plugin
The Combined Grids Plugin is based on the Grid Plugin (http://rsb.info.nih.gov/ij/plugins/grid.html) originally written by Dr.
Wayne Rasband and modified with his permission.
Authors; Daisuke Kinose[1] and Adrian Png[2]
[1] Dr. James Hogg's Lab, the Centre for Heart Lung Innovation in St. Paul's Hospital, University of British Columbia, Canada
[2] IT department, the Centre for Heart Lung Innovation in St. Paul's Hospital, University of British Columbia, Canada
Released on February 5th, 2015
Update on February 5th, 2015
- Each slice in a stacked image can have a grid at different position.
- Output of the slice position in a stack
Implemented Functions:
- Combined, or multi-purpose, point grid with several fine to coarse grid
ratios
- Double lattice square grid with several fine to coarse grid ratios
- Output and autosave of grid parameters
- Manual specification of grid position
- Overlay/remove a grid without destroying the other Overlay elements
- Grid Switch to temporary hide an overlaid grid
Installation and Usage:
- Put "CombinedGridPlugin.jar" into the plugins folder of ImageJ (or Fiji) and
restart the software. Please note that this does
NOT overwrite or replace the existing Grid plugin installed
with ImageJ.
- Open an image in ImageJ.
- Choose "Plugins" > "Grids" > "Combined Grids" in ImageJ.
- Specify your grid settings in the dialog box and click OK.
Notes for the Combined Grids Plugin and Grid History:
- For the Combined Point Grid and the Double Lattice Square grid,
"Area per Point" determines density of the fine grid.
- Grid location by "Fixed Position" in this plugin is same as grid location
with "random-offset" unchecked in the original "Grid" plugin. For
"Combined Point" and "Double Lattice" grids, the first point of the coarse
grid is placed on the first point for the fine grid at the left upper corner.
- When you overlay a new grid, the parameters for the grid are automatically added to the history of previousely overlaid grids.
This list is automatically saved as "CombinedGridsHistory.txt" in the plugin folder.
- If you want to delete grid information from the list of "Grid History",
1. select lines you want to delete in the "Grid History" window,
2. choose "cut" or "clear" in the right click menue or in the "Edit" tab
3. choose "save as..." in the "File" tab and overwrite "CombinedGridsHistory.txt" in the plugins folder of ImageJ.
You can completely clean the list by removing "CombinedGridsHistory.txt" from the folder. This plugin will create a new one.
Notes for the Grid Switch:
- The Grid Switch specifically hides/redraws a grid overlaid by
the "Grid with Combined Grids" plugin. This switch is not compatible with the original Grid Plugin
- When it redraws a grid, the grid is placed on the top of
all the other elements of the overlay.
- You can have multiple grid switches.
- It works for a currently active image. If you have multiple images with grids,
you can change its target by activating another image.
- When the Grid Switch looses its window focus, i.e. minimized, closed, or inactivated, the grid is
redrawn onto the image.

Easiest way to quickly setup jupyter notebook offline.
Often in development we want to activate a set of commands when a file system of project folder changes.
This post will illustrate how to create beautiful slide in jupyter that runs on browser and shared online easily.
This post is used for testing different feature of the blog. Testing math (\(\sum\)) in summary.

This guide provides an overview of the HDFS Federation feature and how to configure and manage the federated cluster.
HDFS has two main layers:
The prior HDFS architecture allows only a single namespace for the entire cluster. A single Namenode manages this namespace. HDFS Federation addresses limitation of the prior architecture by adding support multiple Namenodes/namespaces to HDFS file system.
In order to scale the name service horizontally, federation uses multiple independent Namenodes/namespaces. The Namenodes are federated, that is, the Namenodes are independent and don’t require coordination with each other. The datanodes are used as common storage for blocks by all the Namenodes. Each datanode registers with all the Namenodes in the cluster. Datanodes send periodic heartbeats and block reports and handles commands from the Namenodes.
Users may use ViewFs to create personalized namespace views, where ViewFs is analogous to client side mount tables in some Unix/Linux systems.
Block Pool
A Block Pool is a set of blocks that belong to a single namespace. Datanodes store blocks for all the block pools in the cluster. It is managed independently of other block pools. This allows a namespace to generate Block IDs for new blocks without the need for coordination with the other namespaces. The failure of a Namenode does not prevent the datanode from serving other Namenodes in the cluster.
A Namespace and its block pool together are called Namespace Volume. It is a self-contained unit of management. When a Namenode/namespace is deleted, the corresponding block pool at the datanodes is deleted. Each namespace volume is upgraded as a unit, during cluster upgrade.
ClusterID
A new identifier ClusterID is added to identify all the nodes in the cluster. When a Namenode is formatted, this identifier is provided or auto generated. This ID should be used for formatting the other Namenodes into the cluster.
Federation configuration is backward compatible and allows existing single Namenode configuration to work without any change. The new configuration is designed such that all the nodes in the cluster have same configuration without the need for deploying different configuration based on the type of the node in the cluster.
A new abstraction called NameServiceID is added with federation. The Namenode and its corresponding secondary/backup/checkpointer nodes belong to this. To support single configuration file, the Namenode and secondary/backup/checkpointer configuration parameters are suffixed with NameServiceID and are added to the same configuration file.
Step 1: Add the following parameters to your configuration: dfs.nameservices: Configure with list of comma separated NameServiceIDs. This will be used by Datanodes to determine all the Namenodes in the cluster.
Step 2: For each Namenode and Secondary Namenode/BackupNode/Checkpointer add the following configuration suffixed with the corresponding NameServiceID into the common configuration file.
| Daemon | Configuration Parameter |
|---|---|
| Namenode | dfs.namenode.rpc-address dfs.namenode.servicerpc-address dfs.namenode.http-address dfs.namenode.https-address dfs.namenode.keytab.file dfs.namenode.name.dir dfs.namenode.edits.dir dfs.namenode.checkpoint.dir dfs.namenode.checkpoint.edits.dir |
| Secondary Namenode | dfs.namenode.secondary.http-address dfs.secondary.namenode.keytab.file |
| BackupNode | dfs.namenode.backup.address dfs.secondary.namenode.keytab.file |
Here is an example configuration with two namenodes:
<configuration> <property> <name>dfs.nameservices</name> <value>ns1,ns2</value> </property> <property> <name>dfs.namenode.rpc-address.ns1</name> <value>nn-host1:rpc-port</value> </property> <property> <name>dfs.namenode.http-address.ns1</name> <value>nn-host1:http-port</value> </property> <property> <name>dfs.namenode.secondaryhttp-address.ns1</name> <value>snn-host1:http-port</value> </property> <property> <name>dfs.namenode.rpc-address.ns2</name> <value>nn-host2:rpc-port</value> </property> <property> <name>dfs.namenode.http-address.ns2</name> <value>nn-host2:http-port</value> </property> <property> <name>dfs.namenode.secondaryhttp-address.ns2</name> <value>snn-host2:http-port</value> </property> .... Other common configuration ... </configuration>
Step 1: Format a namenode using the following command:
> $HADOOP_PREFIX_HOME/bin/hdfs namenode -format [-clusterId <cluster_id>]
Choose a unique cluster_id, which will not conflict other clusters in your environment. If it is not provided, then a unique ClusterID is auto generated.
Step 2: Format additional namenode using the following command:
> $HADOOP_PREFIX_HOME/bin/hdfs namenode -format -clusterId <cluster_id>
Note that the cluster_id in step 2 must be same as that of the cluster_id in step 1. If they are different, the additional Namenodes will not be part of the federated cluster.
Older releases supported a single Namenode. Upgrade the cluster to newer release to enable federation During upgrade you can provide a ClusterID as follows:
> $HADOOP_PREFIX_HOME/bin/hdfs start namenode --config $HADOOP_CONF_DIR -upgrade -clusterId <cluster_ID>
If ClusterID is not provided, it is auto generated.
Follow the following steps:
> $HADOOP_PREFIX_HOME/bin/hdfs dfadmin -refreshNameNode <datanode_host_name>:<datanode_rpc_port>
To start the cluster run the following command:
> $HADOOP_PREFIX_HOME/bin/start-dfs.sh
To stop the cluster run the following command:
> $HADOOP_PREFIX_HOME/bin/stop-dfs.sh
These commands can be run from any node where the HDFS configuration is available. The command uses configuration to determine the Namenodes in the cluster and starts the Namenode process on those nodes. The datanodes are started on nodes specified in the slaves file. The script can be used as reference for building your own scripts for starting and stopping the cluster.
Balancer has been changed to work with multiple Namenodes in the cluster to balance the cluster. Balancer can be run using the command:
"$HADOOP_PREFIX"/bin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script "$bin"/hdfs start balancer [-policy <policy>]
Policy could be:
Note that Balancer only balances the data and does not balance the namespace. For the complete command usage, see balancer.
Decommissioning is similar to prior releases. The nodes that need to be decomissioned are added to the exclude file at all the Namenode. Each Namenode decommissions its Block Pool. When all the Namenodes finish decommissioning a datanode, the datanode is considered to be decommissioned.
Step 1: To distributed an exclude file to all the Namenodes, use the following command:
"$HADOOP_PREFIX"/bin/distributed-exclude.sh <exclude_file>
Step 2: Refresh all the Namenodes to pick up the new exclude file.
"$HADOOP_PREFIX"/bin/refresh-namenodes.sh
The above command uses HDFS configuration to determine the Namenodes configured in the cluster and refreshes all the Namenodes to pick up the new exclude file.
Similar to Namenode status web page, a Cluster Web Console is added in federation to monitor the federated cluster at http://<any_nn_host:port>/dfsclusterhealth.jsp. Any Namenode in the cluster can be used to access this web page.

Reports "magic characters", character constants used without declaration.
"Magic character" can result in code whose intention is extremely unclear, and may result in errors if a "magic

Azadi March protests continue as JUI-F blocks highways across country | Pakistan - Geo.tv
by Web DeskThousands of Jamiat Ulema-i-Islam-Fazl (JUI-F) protesters continued to block highways across Pakistan for a fourth consecutive day on Sunday as part of the party's 'Plan B'.
JUI-F and Pashtunkhwa Milli Awami Party workers continued to block the Quetta-Chaman Highway, suspending supply to Afghanistan and affecting the traffic creating long queues of vehicles.
Similarly, in Bannu, JUI-F workers are protesting on the Indus Highway Link Road affecting the flow of traffic flow.
In Karachi, the protests continued for a fourth day on Hub River Road. A large contingent of police and Rangers were present at the site of the sit-in.
Addressing the participants of the sit-in in Khairpur, JUI-F central leader Rashid Soomro said the sit-in plan was a success.
“We have plan till Z, but the government will go before Plan C,” he added.
On Saturday, JUI-F workers continued their sit-in at Dera Ismail Khan National Highway, in Nowshera near GT Road and Hakimabad along with Indus Highway Link Road and Malakand.

Protests and road blockades are also continuing in other parts of the country.
The protests, led by Maulana Fazlur Rehman, began with the ‘Azadi March’ on October 27 from Karachi. Thousands of supporters reached Islamabad on October 31, holding a two-week sit-in on the city’s main highway.
On November 13, Fazl ordered his supporters to disperse across the country to block roads, in what he termed as ‘Plan B’ to topple Prime Minister Imran Khan.
On Thursday protesters blocked the Grand Trunk Road between Islamabad and Afghanistan’s capital Kabul, causing lengthy delays. Similar disruptions were reported in Jacobabad — a city in Sindh linking the province with Balochistan and Punjab.
