Protesting workers dump garbage in front of KMC building in Karachi
by https://www.dawn.com/authors/397/the-newspaper-s-staff-reporter, The Newspaper's Staff ReporterKARACHI: A large number of protesting workers of the city’s municipal administration created chaos for commuters for hours on Tuesday when they obstructed all four gates of the Karachi Metropolitan Corporation’s head office by dumping all kinds of trash.
 They were protesting against non-payment of a 15 per cent increase in the salaries of 14,000 current employees and pensions of 22,000 retired employees as announced by the provincial government in July.
KMC workers’ union president Zulfiqar Ali Shah said that they had given a 48-hour deadline to the KMC administration to disburse the increased amount to them. “The administration would be responsible for the situation if our demands are not met before the deadline,” he warned.
Witnesses said that the protesting workers, who also chanted slogans against the KMC administration and Mayor Wasim Akhtar, did not let the KMC clear the garbage till 3pm, although several trucks reached the spot for garbage removal from M.A. Jinnah Road.
Sources said that the KMC had requested the Sindh Solid Waste Management Board for removal of the garbage from the four gates of the head office, but to no avail as the SSWMB refused to take any action apprehending damage to their vehicles by the protesters. Later, the garbage was removed by the KMC.
They said that the workers had also planned to litter the main roads and residence of government officials if their demands were not met.

A KMC spokesman said that the municipal administration could not pay the raised amount to the workers due to shortage of funds.

Aqua Artificial Intelligence¶
Qiskit Aqua Artificial Intelligence (AI) is a set of tools and algorithms that enable experimenting with AI problems via quantum computing. Aqua AI is the only end-to-end software stack that translates AI-specific problems into inputs for one of the Quantum Algorithms in Aqua: A Library of Quantum Algorithms, which in turn uses Qiskit Terra for the actual quantum computation on top a quantum simulator or a real quantum hardware device.
Aqua AI allows users with different levels of experience to execute AI experiments and contribute to the quantum computing AI software stack. Users with a pure AI background or interests can continue to configure AI problems without having to learn the details of quantum computing.
Applicable Algorithms¶
There are numerous algorithms from Aqua: A Library of Quantum Algorithms that can be applied to AI problems.
AI-specific Quantum Algorithms¶
Aqua AI comes with two quantum Support Vector Machine (SVM) algorithms already integrated into the Aqua library:
- The Support Vector Machine Quantum Kernel (SVM Q Kernel) algorithm applies to classification problems that require a feature map for which computing the kernel is not efficient classically. This means that the required computational resources are expected to scale exponentially with the size of the problem. SVM Q Kernel uses a Quantum processor to solve this problem by a direct estimation of the kernel in the feature space. The method used falls in the category of what is called supervised learning, consisting of a training phase (where the kernel is calculated and the support vectors obtained) and a test or classification phase (where new labelless data is classified according to the solution found in the training phase).
- The Support Vector Machine Variational (SVM Variational) algorithm also applies to classification problems that require a feature map for which computing the kernel is not efficient classically. SVM Variational uses the variational method to solve such problems in a quantum processor. Specifically, it optimizes a parameterized quantum circuit to provide a solution that cleanly separates the data.
General Quantum Algorithms for AI¶
Other quantum algorithms available in Aqua that can be used to experiment with AI problems include Variational Quantum Eigensolver (VQE), Quantum Approximate Optimization Algorithm (QAOA), Quantum Phase Estimation (QPE), Iterative Quantum Phase Estimation (IQPE) and Quantum Grover Search.
Classical Reference Algorithms for AI¶
To produce reference values and compare and contrast results during experimentation, the Aqua library of Classical Reference Algorithms also includes the Support Vector Machine Radial Basis Function Kernel (SVM RBF Kernel) classical algorithm.
Contributing to Aqua AI¶
Research and developers interested in Contributing to Aqua with new AI-specific capabilities can take advantage of the modular architecture of Aqua and easily extend Aqua with more algorithms or algorithm components, such as new Oracles for the Quantum Grover Search algorithm, new Optimizers and Variational Forms for Variational Quantum Eigensolver (VQE) and Quantum Approximate Optimization Algorithm (QAOA), and new Inverse Quantum Fourier Transforms for Quantum Phase Estimation (QPE) and Iterative Quantum Phase Estimation (IQPE).
Examples¶
The artificial_intelligence
folder of the Aqua Tutorials GitHub Repository contains numerous
Jupyter Notebooks and input data files
explaining how to use Aqua AI.

Does the new Tabular Model change things? What’s the difference between a data warehouse and a data mart? Is there any hardware that is optimized for a data warehouse? Join this session for the answers to all these questions. You’ll leave with information that will amaze your boss and lead to a big raise… – or at least lead you down the correct path to adding business value to your organization!
Speaker(s): James Serra,
Abstract:
In this Star Trek-themed presentation, we will explain the terms and concepts important to understand when participating in projects involving SQL Server Analysis Services (SSAS). You’ll learn the key differences between SSAS Multidimensional Model (Cubes) and SSAS Tabular Model. You’ll also learn the definitions and examples of key terms for each model, including but not limited to: measure groups, measures, dimensions, attributes, and hierarchies in the SSAS Multidimensional Model and tables, columns, and calculated measures in the SSAS Tabular Model. We will also demonstrate the basics of browsing of both Multidimensional and Tabular models using Excel 2013.
Speaker(s): Doug Lane,
Abstract:
If you’re like me, you’ve been using SQL Trace and Profiler since you started using SQL Server. They’re like old friends, tried and true. You know how they work, you know what you can capture, you know how to find the data you need. But now you’ve been told that your good friends have been deprecated in SQL Server 2012, and you need to become best friends with Extended Events. What is THAT all about? It’s ok. Really. In this session we’ll look at Profiler and Extended Events side by side to see how easy it is to transition to Extended Events. We’ll step through real world examples using Extended Events to do what you’re used to doing with Trace, and even more. You can find the time learn Extended Events…today.

Abstract:
One of the hottest trends in analytics right now is geospatial reporting. Long gone are the days of viewing region based data in a grid. Now it is possible to provide users with additional insight on the regional performance of business. In this session, Julie will show you three options for creating and delivering these analytics. First SQL Server Reporting Services 2012 will be presented to show how we can create custom shape objects to conform with business defined regions. Secondly, using the power of Excel 2013, Bing Maps and GeoFlow, learn how to build captivating visualizations directly in Excel. Finally, we'll show how easy it is to build interactive maps using Power View.
Speaker(s): Julie Koesmarno,
Abstract:
With the release of SQL 2012, Analysis Services (SSAS) has seen some major changes. An entire new method of modelling analytic data has emerged and it's called Tabular Mode Analysis Services. In addition to that, a new semantic layer has been added to the tool, the Business Intelligence Semantic Model (BISM), which will help to bring the two modes -- Multidimensional and Tabular -- into one level playing arena. In this session, attendees will gain understanding of what Multidimensional and Tabular modelling IS, as well as how the BISM layer helps to translate user requests to ensure no confusion is made. Attendees will also learn how to BUILD a Tabular model, and will help design a solution live during the presentation.
Speaker(s): Josh Fennessy,
Abstract:
Never given time or care, never forming good relationships, becoming bloated, corrupt and rife with indistinguishable copies, and all so horrifyingly pervasive in society. But enough about the Kardashians, what about YOUR DATA? If you want to straighten it out and prevent it from going too far in the first place, this session is for you. We will cover constraint basics (not null, check, primary key/unique, foreign keys), provide standard use cases, and address misconceptions about constraint use and performance. We will also look at triggers and application logic and why these are NOT substitutes for (but can effectively complement) good constraint usage. Attendees will enjoy learning how to keep THEIR data off the tabloid page!
Speaker(s): Rob Volk,
Abstract:
As an admin, we need to keep an eye on storage: What is the total size and available size on disk devices? What about mount points? How much space does each database take? What about breaking that down into schemas, tables, data size, and index size? Granted, some of that can be seen through Management Studio reports, but what if we want to keep a historical record of all that for planning and trending purposes? What if we are on a tight budget and cannot afford monitoring software. In this session, I will explain and demo a PowerShell/SQL Server combo solution that is simple, elegant, and works! You will come away with code and instructions on how to implement it.
Speaker(s): Haidong Ji,
Abstract:
A lot of database professionals today do not have a Computer-Science Degree so they never attended a “Introduction to Databases” course. In this session we are trying to fix at least one thing and we’ll look in depth at the three types of join operations, visualize how their algorithms work in order to understand how query plans are computed, explain why these join operations have very different performance characteristics and why the optimizer chooses a specific join operator to use in a query plan. Will demonstrate that empirical cost calculations are similar to what Query Optimizer actually outputs. Good understanding of join algorithms is vital in order to diagnose and remedy issues related to bad query plans.
Speaker(s): Luke Jian,
Abstract:
Database statistics are not made up numbers, like the statistics you may hear on TV or read in a news article. They are critical metadata used by SQL Server’s query optimizer. In this session, we will look at statistics from the ground up and remove the mystery that surrounds them. Demos and real-world examples will be used to explain what statistics are, why you should care about them, and what you can control. By the end of the session, you will understand: • How to view statistics and interpret the histogram • How and when to update statistics • How statistics affect the query optimizer • When you can let SQL Server manage statistics, and when you need to step in
Speaker(s): Erin Stellato,
Abstract:
SharePoint makes it easy for users to create their own dashboards but there's more to dashboards than just fast and easy set-up. This session will explore not only the characteristics of an effective BI dashboard using SharePoint 2013, but also the design flaws to avoid. Attend this session and learn how to perform a dashboard makeover. Starting with a review of a dashboard that uses technology correctly but not as effectively as it could, you’ll explore common problems found in dashboards, learn the characteristics of good dashboard design and discover how to implement a dashboard that communicates information clearly and concisely.
Speaker(s): Stacia Varga,
Abstract:
Execution plans are stored after execution in the plan cache. This metadata about how queries are executed can provide insight into how your SQL Server environment is functioning. By using XQuery to browse and search the plan cache you can find potential performance issues and opportunities to tune your queries. This information can be used to help reduce issues related to parallelism, shift queries from using scans to using seek operations, or discover exactly which queries are using what indexes. All of this and more is readily available through the plan cache. In this session we will explore the plan cache and start you on the road to discovery.
Speaker(s): Jason Strate,
Abstract:
Availability Groups, a feature of SQL Server 2012 delivers mission critical high availability and disaster recovery in the same solution. This session covers capabilities, deployment architecutes, how to install, configure, manage and troubleshoot this new feature with best practices of customers who have deployed and are using Availability Groups.
Speaker(s): Ross LoForte,
Abstract:
If you haven't dug in to PowerShell at this point, you're missing out on some amazing, powerful, practical stuff that could save you time every day. PowerShell does have a learning curve at the outset, especially for those not already familiar with OO concepts or programming in a language like C#, so this introductory session will go through the very basics of PowerShell syntax. If that collection of pipes and hyphens and curly braces seems to be written in some incomprehensible foreign language, this session is for you. At the end of the session you should have a grasp of how and why a PowerShell script does what it does, and the confidence to dig in deeper and begin using POSH scripts in your own work.
Speaker(s): Merrill Aldrich,
Abstract:
These terms seem to be thrown around all the time – but what do they all mean? In this session we’ll explore the different isolation levels in SQL Server and how they affect the way that blocking and locking behave within the database engine. We’ll dive into the most common locks and how they can be leveraged and avoided to improve your application experience. Once locks are explored, we’ll discuss the dreaded deadlock and discuss techniques to detect and mitigate this troublemaker in your environment.
Speaker(s): Kyle Neier,
Abstract:

It’s so exciting you’ll want to upgrade right away!
Speaker(s): Chris Webb,
Abstract:
When should you favor a NoSQL store over SQL Server, or consider polyglot persistence? In military and police operations, the rules of engagement determine when, where, and how force shall be used. As the “data police”, we are responsible for determining when, where, and how data is stored. As SQL Server professionals, it tends to be our first choice, even when there are other data storage options that are a ‘more natural’ fit. In this session, Rick and Dave will start with the NoSQL basics, and then dive into the different categories of NoSQL stores while explaining what each type is well suited for. (Pair Presented with Dave Valentine @IngeniousSQL)
Speaker(s): Rick Krueger,
Abstract:
When do you use a sparkline, column, or line chart? How do you create a business scorecard – and with what tool? Using Excel, Power View, and Report Builder, this session will guide you through the choices and help you apply the right visual to your business data. Come see what well-known industry experts have to say about the correct use of visualization choices and techniques, colors, backgrounds, borders, and 3-D effects. Then see demonstrations of how to create those rich visuals in the different reporting tools, used with PowerPivot and tabular semantic models.
Speaker(s): Paul Turley,
Abstract:

I don’t and that is why we’re going to look at methods to upgrade or migrate SQL Server 2005, SQL Server 2008 and SQL Server 2008 R2 up to SQL Server 2012 with as little downtime as possible - minutes. In this session, we’ll see how mirroring, log shipping and even replication, can make us look like DBA Rock stars at upgrade time.
Speaker(s): Ted Krueger,
Abstract:
As protectors of arguably, the most important asset companies’ have we are tasked with ensuring quality, security and performance. However the ways in which we utilize and obtain those assets are often not formalized and therefore suffer from degraded quality. Let's discuss some strategies that can be implemented to not only raise the bar of quality, but also make you sleep easier at night.
Speaker(s): Aaron Lowe,
Abstract:
Back in the old days, compression and databases was a really bad idea. Now, with powerful CPUs we can use to both improve performance and save disk space. We will cover the basics of how all compression and deduplication works, and then we will learn how SQL Server page and row compression work, and the special compression that is used in SQL 2012 Columnstore Indexes. We will demo performance and space savings in using compression.
Speaker(s): Joseph D'Antoni,
Abstract:
SSRS 2008 R2 has been a game changer for SQL Server in terms of visualization techniques.

Speaker(s): Hope Foley,
Abstract:
You’ve spent the afternoon sweating over your T-SQL query. You’ve wrung out all of the wrinkles. It’s deployed, it’s running… now its waiting. In SQL Server the most performant query can become a problem query if there aren’t any resources in the SQL Server for it to use. In this session, we’ll look at wait statistics and what they are. We’ll look into how they are accumulated and how they can be monitored. By the end of the session, you’ll be equipped with the tools needed to determine if there are resource issues in your environment and methods to start mitigating them.

Speaker(s): Kathi Kellenberger,
Abstract:
Managing data in ever-growing transaction and history tables can be challenging. Activities with large chunks of data such as moving data to archive tables, batch-importing many rows, or defragging an entire table when only the active portion changes introduces heavy I/O and blocking. Table partitioning seamlessly solves a host of headaches with minimal effort. Ever wanted to truncate or defrag part of a table, or insert an entire staging table of data into another table in milliseconds instead of hours? Come see what partitioning can provide for you.
Speaker(s): Eddie Wuerch,
Abstract:
Until 2005, SQL Server was a very pessimistic RDBMS. However with the introduction of the Read Committed Snapshot database option and the new Snapshot Isolation level, that is no longer the case. After a high level look at all SQL Server isolation levels, we’ll spend the majority of this session discussing the implementation of optimistic concurrency control in SQL Server. We’ll look at the benefits and drawbacks of using an optimistic isolation level and discuss use cases where it may or may not be appropriate. Come learn how to put one of the more powerful, but least understood, aspects of SQL Server to work for you!
Speaker(s): Paul Timmerman,
Abstract:
SQL Server 2012 brings a wide range of changes from its previous versions - one key change is the way SQL Server memory is managed. With releases prior to SQL Server 2012, there were 2 memory managers, these have been merged into 1 with the latest version, and that’s just the start of the changes for SQL Server memory. This session will dive into questions related to memory primarily for SQL Server 2012.
Speaker(s): Neil Hambly,
Abstract:

Speaker(s): Ed Leighton-Dick,
Abstract:
Have you ever read a job description (or needed to hire one yourself) asking specifically for a “BI DBA” and wondered what exactly that means? In this session we will discuss the expectations of the role, what the various pieces of the Microsoft BI stack are and what administrative components and gotchas are involved for each one. If you need to unveil the mysteries and intricacies of administrating an SSIS, SSAS and/or SSRS environment from a DBA perspective then check this session out!
Speaker(s): Jorge Segarra,
Abstract:
With the release of SQL Server 2012 one of the biggest changes for SSIS Administration was the addition of the Integration Services Catalog and using parameters. The Catalog is the storage and logging location for SSIS 2012. Parameters are the new configurations in SSIS 2012 and once you start using them you will never go back. Package Variables, Configuration Strings, Package properties can all be configured using Parameters. You will learn how to create the catalog, use parameters to deploy packages through different environments and use the built in reporting to monitor packages as they run.

The nunuStudio editor is where nunu applications are developed it provides tools for creating and editing objects inside the 3D world. If you have ever worked with another similar frameworks (unity, playcanvas, godot, etc) or with 3D modeling software (blender, maya, cinema4d, etc) some of the concepts bellow might be already familiar to you.
Objects are organized in a tree structure (visible on the red area bellow), each object has childrens, that inherit the parent object position, scale and rotation. If a parent object is moved the children object is moved with it.
Objects can be selected on the object explorer with mouse left click, when a object is selected the object panel (in blue), is filled with data regarding that object. In the object panel its possible to manually change every attribute of an object (position, name, color, etc).
The left side of the window is used to choose tools and add objects to the scene, tools are used to interact directly using the mouse with objects in the 3D space, the following tools are available:
Selection tool, selects objects with mouse left click, objects can also be selected by double clicking on then (even if the selection tool is not active)
Move tool, used to move objects
Resize tool, used to resize objects
Rotate tool, used to rotate objects
Bellow the tool selection zone, there is the object add zone, where its possible to select and add objects to the scene currently selected on the object explorer. When dragging the mouse over each option a new box appears showing objects for each category available.
The resource explorer zone (in green), is used to manage all available resources (images, videos, fonts, etc), import new resources into the project (clicking on the import menu or simply by dragging them into the resource explorer) or even export resources from the project to the host system.
The mouse is used to move the camera inside the scene editor. There are two modes of navigation available, by default the Free navigation mode is enabled.
To rotate the camera press the mouse left button and move the mouse around (the camera moves similarly to how a camera moves in a FPS game).
To move the camera press the mouse right button and move the mouse
To move vertically press the mouse middle button and move the mouse up and down
To approach the camera use the mouse scrolling wheel, or pinch with your fingers if you are using a trackpad.
To add your first object to the scene (lets use as example a sphere) move the mouse to the 5th icon in left side bar, and select the sphere icon using the mouse left button.
Now select the added object with the selection tool and after that choose the move tool and try to move the added object aroud.
After adding an object to the editor we can change its properties, all objects in nunuStudio have a name, position, rotation and scale.
To select an object you can select the Selection tool in the right side bar and click on top of the object in the scene editor area, alternatively you can also click on the object in the object explorer.
To test the program press the run button on the top bar, or press the F5 key, to stop it press the stop button or press the F5 again.


India is increasingly using space technology for its development of which satellite communications is a major component. Now the communication Satellites are generally designed to work in the microwave band of the spectrum, so they can also be called as Microwave Repeater.
Analog Signals, being more susceptible to noise and interference, are being replaced by their digital counterparts. Transmission at physical layer still takes place in analog but the processing of signals is done in the digital domain
DIGITAL TELEVISION
Digital Television (DTV) is the transmission of audio and video by digitally processed and multiplexed signal, in contrast to the totally analog and channel separated signals used by analog television. Digital TV can support more than one program in the same channel bandwidth. Several regions of the world are in different stages of adaptation and are implementing different broadcasting standards. Below are the different widely used digital television broadcasting standards (DTB):
-
Digital Video Broadcasting (DVB) uses coded orthogonal frequency-division multiplexing (OFDM) modulation and supports hierarchical transmission. This standard has been adopted in Europe, Singapore, Australia and New Zealand.
-
Advanced Television System Committee (ATSC) uses eight-level vestigial sideband (8VSB) for terrestrial broadcasting. This standard has been adopted by six countries: United States, Canada, Mexico, South Korea, Dominican Republic and Honduras.
-
Integrated Services Digital Broadcasting (ISDB) utilizes OFDM and two-dimensional interleaving and has been adopted in Japan and the Philippines.
-
Digital Terrestrial Multimedia Broadcasting (DTMB) adopts time-domain synchronous (TDS) OFDM technology with a pseudo-random signal frame to serve as the guard interval (GI) of the OFDM block and the training symbol. The DTMB standard has been adopted in the People’s Republic of China, including Hong Kong and Macau.
-
Digital Multimedia Broadcasting (DMB) is a digital radio transmission technology developed in South Korea as part of the national IT project for sending multimedia such as TV, radio, and datacasting to mobile devices such as mobile phones, laptops, and GPS navigation systems.
Digital Video Broadcasting
Digital Video Broadcasting (DVB) is a set of standards designed to broadcast video and audio signals via various channels including cable channel, Satellite channel, terrestrial channel and Microwave channel. They are maintained by an international industry consortium with more than 270 members and are published by European Telecommunications Standards Institute (ETSI). DVB distribute data using a variety of approaches including DVB-C (DVB Cable), DVB-S (DVB Satellite), DVB-T (DVB Terrestrial ) and DVB-M (DVB Microwave).
How is Satellite channel different from other terrestrial channels?Well, A Satellite channel has no ‘Multipath Effect’. It is a non-linear transmission channel having limited resources on board
Nonlinear characteristics of the satellite channel largely depend on the High power amplifier (HPA) used at the satellite transponder. The HPA nonlinearity changes both the amplitude and relative positions of the constellation points of the transmitted signal, thus distorting the signal.
DVB for Satellite Channel (DVB-S)
DVB-S was introduced in 1995 for the transmission of video signals over the satellite channel. With the advent of advanced video encoding techniques like H.264 and H.265 (a video compression technique which helps compress higher resolution videos and allow smooth playback by the processors on board of any computing device- also called HDTV), a higher data rate transmission system was required to transmit these HDTV signals over the satellite channel.
In 2003, the second generation of DVB-S was developed and was called DVB-S2 (DVB-S second generation). It had higher bandwidth efficiency, higher transmission rates and was more robust against transmission errors. It employed APSK modulation for the first time for transmission of video signals over the satellite channel. Two new key features that were added compared to the DVB-S standard are:
- A powerful coding scheme based on a modern LDPC code. For low encoding complexity, the LDPC codes chosen have a special structure, also known as Irregular Repeat-Accumulate codes.
- VCM (Variable Coding and Modulation) and ACM (Adaptive Coding and Modulation) modes, which allow optimizing bandwidth utilization by dynamically changing transmission parameters.
In 2014, DVB-S2X (stands for DVB-S2 extension) was introduced which is the advanced version of DVB-S2. It uses higher order APSK modulation techniques which greatly increases the bandwidth efficiency allowing more data to be sent over the same Satellite channel.
Constellation Diagram
A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying.[1] It displays the signal as a two-dimensional XY-plane scatter diagram in the complex plane at symbol sampling instants. In a more abstract sense, it represents the possible symbols that may be selected by a given modulation scheme as points in the complex plane. Measured constellation diagrams can be used to recognize the type of interference and distortion in a signal
Interfering Tone or Spur
An interfering signal can cause the amplitude and phase of the transmitted signal to be different each time the signal passes through the same state. This will result in a spread at the symbol locations in the constellation diagram. The random smearing of the points indicates noise, but a circling of the symbols around the constellation states indicates there may be a spur or interfering tone
The radius of the circle is proportional to the amplitude of the interfering signal, but this display format contains no information about the interfering frequency, which may be the key to identifying the cause. The presence of spurs on a modulated signal may be difficult to determine on a constellation display or through spectrum analysis. An alternative parameter can be used to check signal quality: EVM
The magnitude of the error vector versus time graph may hint that the error observed is sinusoidal in nature, but what is really needed is a method to determine the frequency of the spur.
The error vector spectrum can indicate the frequency of spurious signals that cannot be observed on traditional spectrum analyzers or on a constellation display. This interfering tone could cause the receiver to fail many of the performance verification tests.
BER
Bit Error Rate(BER) is usually considered by many to be the best measurement to verify receiver performance but BER testing is not always possible in the subsystems of a Digital Radio Receiver.
BER can indicate a problem exists, but may not help in indicating the source of the problem. Often BER is synonymous with the other performance metrics, such as signal to Noise Ratio (SNR), since direct relationship exists between them. However, for BER measurements, it is incumbent that the signal must be demodulated first at the receiver side which is not required in case of EVM
Now as we know, In Satellite systems, apart from noise and interference, the channel nonlinearity also causes problems. The nonlinearity exists because the working mode of the power amplifier board is set near the saturation point in order to reach the maximum level for the transmitted signal. The nonlinear signal distortions, similarly to the noise and interference in the radio channel, are the reasons for the increase of error probability.
The setup used for calculation of BER is shown in the figure below. Data generator is a memoryless discrete source block which generates a stream of data. To increase the transmitted data per unit time, source coding is done by the APSK Mapper block which maps the generated bit sequence into different symbols
To enable physical transmission of these symbols over the physical medium, the symbols is transformed into pulse using root raised cosine function with a roll-off factor of α = 0:35. The choice of pulse shaper function determines the amount of Inter-Symbol Interference (ISI), which the communication system can mitigate.
Additive White Gaussian Noise (AWGN) Channel is the simplest noise model, often used to simulate Satellite channel and deep space communication links. AWGN block performs a linear addition of independent Gaussian noise samples to its input signal. QAM (Quadrature Amplitude Modulation) implements a QAM receiver with demodulation and detection functions.
The BER analyzer block automatically determines the reference signal. BER is capable of sweeping simulation, producing swept BER output. An optional variable to be swept along with the value of each sweep can be specified using the name of a variable to sweep and the vector of values for that variable. BER block starts a new sweep when a minimun number of errors per pass has been detected or when all the symbols contained in the maximum number of trial blocks per sweep have been processed.
EVM
An ideal signal or the signal sent by transmitter would have all the constellation points precisely at the ideal location. However, due to distortion of the signal in the channel, these constellation points end up at a different position in the receiver. This shift in the position of the constellation points is measured at the receiver. Error Vector Magnitude (EVM) is a measure of how far these constellation points are from their ideal location. The setup used for calculation of EVM is shown in the figure below. The same setup with slight modification is used, for calculating the EVM. The different blocks used here are a splitter and a Vector Signal Analyzer.
A splitter splits the incoming signal into n-connected output ports whereas a vector signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the Intermediate Frequency bandwidth of the instrument. It gathers the reference signal and measured signal and acts as a sweep controller. The spectrum analysis by a VSA consists of two stages – down-convert & digitize stage and Digital signal processing and display stage. A portion of the input signal spectrum is down-converted (using a voltagecontrolled oscillator and a mixer) to the center frequency of a band-pass filter. The use of a voltage-controlled oscillator allows for consideration of different carrier frequencies.
After the conversion to an intermediate frequency, the signal is filtered in order to band-limit the signal and prevent aliasing. The signal is then digitized using an analog-to-digital converter. The sampling rate is often varied in relation to the frequency span under consideration.
EVM is the Root-mean-square (RMS) value of the difference between a collection of measured symbols and ideal symbols.
EVM vs BER for APSK Modulation
After plotting the EVM values against BER, we get an EVM-BER curve which is shown below in the figure. The figure 9 below shows the EVM-BER curves for the APSK modulations like APSK-16, APSK-64, APSK-256 and APSK-512 along with QAM modulations (QAM-16 and QAM-64). The EVM-BER curve for the 16-QAM and 64-QAM are already established results which have been reconstructed to justify the correctness of the APSK plots.
Minimum EVM required corresponding to a given value of BER can be easily determined from the figure above. While BER( 10^-5) is used by many engineers as a standard signal performance metric, it takes time to measure the signal performance. In case of a communication system that employs Automatic repeat request (ARQ) system, retransmissions cause a delay in taking BER measurement. In such cases, EVM can be helpful as it quickly sweeps through the signal and determines the quality of the signal transmission. This saves a lot of cycles which decreases the latency. Taking EVM measurements requires only a Vector signal analyzer which also measures a lot of other parameters. Hence, EVM measurement doesn’t require any special instrument which makes it cost effective.

Jensen Chapter 1 pg. 14-20
Resolution
- Resolution is the smallest interval measurable by a scientific instrument.
- We're referring to the resolving power of the imagining device.
- It's related to the level of detail in the image and therefore the information content.
Types of Resolution
- Spectral
- Radiometric
- Spatial
- Temporal
- Polarization
Spectral Resolution
- The number and size of spectral regions the imaging device records data in
- For example, a particular sensor may have multiple 'bands' that record within the
blue, green, red, near-infrared, and thermal infrared parts of the spectrum.
(source: Jensen, 2006)
Spectral Resolution
(source: USGS, 2015)
Airborne Visible Infrared
Imaging Spectrometer (AVIRIS)
data cube of Sullivan's Island
obtained on October 26, 1998
Radiometric Resolution
- The sensitivity of detectors to small differences in electromagnetic energy.
(source: Lindsay, 2013)
Spatial Resolution
- Related to the smallest distinguishable ground feature in the image, i.e. the detail.
- Influenced mainly by image scale.
- Limited by the size and number of silver halide crystals in film cameras and by
the number of charge-coupled device (CCD) detectors for digital cameras
- Can be improved using a telephoto lens.
(source: Jensen, 2006)
(source: Jensen, 2006)
Spatial Resolution
- A compromise exists between the spectral resolution and the spatial resolution.
- Panchromatic bands are usually finer spatial resolution
than multispectral bands.
- This can be achieved because of the relatively coarse spectral resolution of pan images.
The Resolution Compromise
(source: DigitalGlobe)
- 0.46 m pan (resampled to 0.5 m); 1.8 m MS bands
- 11-bit spectral res (2048 grey tones)

Temporal Resolution
- How often the sensor acquires data, e.g. every 30 days.
- Temporal resolution is partly determined by orbital characteristics.

Polarization
- Unpolarized energy vibrates in all possible directions perpendicular to the
direction of travel.
- Radar systems can detect polarized EMR.
(source: Jensen, 2006)
Polarization
- HH and VV configurations produce like-polarized radar imagery.
- HV and VH configurations produce cross-polarized imagery.

When you open a file that is on the recently opened file list HexEdit Pro restores the display the way it was for that file when you last had it opened. These settings include which area(s) are displayed, the character set, number of columns, font, modifiability, etc as well as the current color scheme.
However, when you open a different file or create a new file HexEdit Pro uses the default display settings for showing that file. You can change the default display settings using the Window Display Options page of the Options dialog. To do this open the page and adjust any or all of the options in that page as desired, then click the Save As Default button. If you don't want to change the settings for the active window click the Cancel button else click the OK or Apply button.
This will not change the default color scheme. When a new file is opened the "ASCII default" color scheme is used. To set the colors for this color scheme use color Options page of the Options dialog.

This puzzle is a prelude to a hard one, and also to an optimization (code golf) puzzle. It is quite easy, the aim is to make your androids progress in a maze of floors and elevators, sacrificing some of them to change direction.
Note the usage of * in scanf formatting, to skip an item.
#include <stdlib.h> #include <stdio.h> int main(int argc, char** argv) { // number of floors, exit position on last floor, a floor nb, a position int N, exit, f, pos; scanf("%d%*d%*d%*d%d%*d%*d%*d", &N, &exit); // elevators positions int elevators[N]; for (int i = 0; i < N-1; i++) { scanf("%d", &f); scanf("%d", &elevators[f]); } elevators[N-1] = exit; char direction[5]; while (1) { scanf("%d%d%s", &f, &pos, direction); // -1 if direction is LEFT, 1 if it is right int d = strcmp(direction, "M"); if (f == -1) printf("WAIT\n"); else if ((d < 0 && pos < elevators[f]) || (d > 0 && pos > elevators[f]) ) printf("BLOCK\n"); else printf("WAIT\n"); } return EXIT_SUCCESS; }
