Cassandra Day NY 2014: Getting Started with the DataStax C# Driver
So you’ve grabbed the latest 2.0 beta of DataStax C# driver from NuGet. Now what? In this talk, Luke will walk you through some of the basics of the C# driver--how to bootstrap the driver and connect to a cluster, execute statements, and retrieve result sets. Wondering what the difference between a PreparedStatement and a SimpleStatement is? Not sure what the appropriate lifetime for a Cluster or a Session object is and whether you should reuse one (from multiple threads)? What about ADO.NET and LINQ support? We’ll cover this and more, so that you can get on with building applications on top of Cassandra and .NET.

Vert.x - Reactive & Distributed [Devoxx version]
During past years, the requirements for modern applications have increased from gigabytes of data to terabytes, from thousands of requests per second to millions, from seconds of response time to milliseconds, and this list can be continued. Until now, most of these problems have been solved using the Microservices architecture, but what's next? What next approach should we apply where Microservices fail? In this presentation, we will overview modern approaches to application development with Reactive and Distributed architecture and see how Vert.x help to implement such solutions.
Getting Started with Datatsax .Net Driver
This document provides an overview of getting started with the DataStax .NET driver. It discusses downloading and configuring the driver, creating statements to execute queries, handling result sets, and features like automatic paging and lightweight transactions. It also briefly mentions LINQ support, ADO.NET support, and links to additional resources like the sample KillrVideo application and Planet Cassandra website.
Java Concurrency
Carol McDonald gave a presentation on Java concurrency utilities introduced in J2SE 5.0. She discussed motivation for improved concurrency tools, common concurrency issues, and key utilities like Executor framework, locks, synchronizers, and concurrent collections. The utilities make concurrent programming easier and improve performance of multithreaded Java applications.
比XML更好用的Java Annotation
The document discusses using annotations in Java, providing examples of annotations for servlets, EJBs, web services, CDI, and using frameworks like JUnit, Spring, Javassist, and ASM. It presents code samples to define servlets, session beans, RESTful and SOAP web services, and component injection using annotations instead of XML configurations. The document also demonstrates how to programmatically read annotation values and metadata using reflection, Javassist, and ASM.

4Developers 2018: Evolution of C++ Class Design (Mariusz Łapiński)
Since the beginnings of C++, classes are the basic building block of any self-respecting application. The combination of data and its relevant functionality heavily impacts the way we modularize the program, design APIs, construct and reuse the code - think of software in general.
In the previous era, C++ was a hammer for every nail, providing secure high-level abstractions without sacrifice of the superior performance. Yet during the past decades, competing technologies dethroned it out of many domains. As the language evolved to prevail its principal advantages, so did the way classes are programmed.

Description (Part A) In this lab you will write a Queue implementati.pdf
Description (Part A) In this lab you will write a Queue implementation called CoolQueue, which
closely matches the java.util.Queue collection, except with fewer methods. Test code is provided
that allows you to compare your queue to the one in java.util.Queue, which you can assume is
completely correct.
Getting Started
Create a project called Lab9 and download following files:
QueueInterface.java
TestProgram.java
CoolQueue.java
Fill in the supplied CoolQueue.java to make it implement the provided QueueInterface methods.
Then use the TestProgram to verify that your code works. Here are the methods in the interface:
public interface QueueInterface {
// Add object onto rear of queue
public abstract boolean add(E item);
// Remove object from front of queue // Throws NoSuchElementException if empty
public abstract E remove();
// Peek object from front of queue // Throws NoSuchElementException if empty
public abstract E element();
// Check for empty
public abstract boolean isEmpty();
// Returns size
public abstract int size();
// Clears queue
public abstract void clear();
// Various searches
public abstract boolean contains(Object o);
// Override toString
public abstract String toString(); }
Instructions
Inherit the interface provided above.
The Queue is a generic data structure, so declare an LinkedList.
HINT: You should use the first entry or head of the LinkedList as the front of the queue.
HINT: You should use the last entry or tail of the LinkedList as the rear of the queue.
You must not use add(), remove(), or element() in the LinkedList object.
You must implement toString() first, format is the same as LinkedList.toString().
Incremental development, so test one method at a time.
Review the TestProgram to see what is tested by each test number, 1 through 7.
Below is the CoolQueue.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
class CoolQueue implements QueueInterface {
// Underlying data structure
// Default constructor
}
Below is the TestProgram.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
import java.util.Queue;
import java.util.Random;
public class TestProgram {
static Random random = new Random();
public static void main(String[] args) {
// Make a Java stack
Queue javaQueue = new LinkedList<>();
// Make a student stack
CoolQueue coolQueue = new CoolQueue<>();
// Which test?
int testNumber = Integer.parseInt(args[0]);
switch (testNumber) {
case 1: // testAdd
System.err.println(\"testAdd: verifying add() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
System.err.println(\"Java Queue: \" + javaQueue);
System.err.println(\"Cool Queue: \" + coolQueue);
break;
case 2: // testRemove
System.err.println(\"testRemove: verifying remove() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
// Legal removes
for (int i = 0; i < 10; i++) {
System.err.printf(\"javaQueue.remove(): %4s, coolQueue.remove(): %4s\ \",
javaQueue.remove(), coolQueue.remove());
}
// Queue e.
Auto-GWT : Better GWT Programming with Xtend
Presentation from GWT.create 2015 EU
Auto-GWT (auto-gwt.org) is a library for the Google Web Toolkit, that frees your code from unneccessary and complicated boilerplate and at the same time pushes the IDE capabilities to a new level. Auto-GWT is based on Xtend (xtendlang.org).
Xtend is a modern programming language that is 100% compatibly with existing Java libraries and even translates to readable Java source code. With it's slick syntax and powerful features such as lambdas, operator overloading and compile-time macros you can turn any verbose piece of Java code into a small and elegant piece of expressive Xtend code.
In this session we will show how Xtend can be used to program GWT applications and how well the typical GWT idioms are supported by the language.

Java concurrency
This document discusses Java concurrency. It begins with an agenda and then covers key topics like shared state, thread safety, concurrency problems and symptoms, and Java concurrency methods. Facts about processors, caches and memory interactions that can impact concurrency are presented. Examples are provided to illustrate concurrency issues like visibility and atomicity. Common concurrency problems like invalid states and their symptoms are outlined. Finally, Java concurrency methods like thread confinement, immutability, volatile variables, and synchronized are defined and code examples are shown.
EVERYTHING ABOUT STATIC CODE ANALYSIS FOR A JAVA PROGRAMMER
Static code analysis tools can analyze Java programs to find defects without executing the code. They use techniques like pattern matching, type inference, data flow analysis and symbolic execution. PVS-Studio is a static analysis tool for Java that was created using lessons from a C++ analyzer. It finds bugs like integer divisions by zero, dead code, copy-paste errors and other defects. Integrating static analysis into development processes helps improve code quality over time by detecting and fixing issues early.
Jdbc[1]
This document discusses using JDBC to access databases from Java applications like JSP pages. It covers loading the appropriate JDBC driver, establishing a connection with the database using a connection URL, executing SQL statements using Statement objects to retrieve and process result sets, and closing the connection when done. The core steps are to load the driver, get a connection, create statements, execute queries/updates, process results, and close the connection.

Java byte code in practice
At first glance, Java byte code can appear to be some low level magic that is both hard to understand and effectively irrelevant to application developers. However, neither is true. With only little practice, Java byte code becomes easy to read and can give true insights into the functioning of a Java program. In this talk, we will cast light on compiled Java code and its interplay with the Java virtual machine. In the process, we will look into the evolution of byte code over the recent major releases with features such as dynamic method invocation which is the basis to Java 8 lambda expressions. Finally, we will learn about tools for the run time generation of Java classes and how these tools are used to build modern frameworks and libraries. Among those tools, I present Byte Buddy, an open source tool of my own efforts and an attempt to considerably simplify run time code generation in Java.
Building Scalable Stateless Applications with RxJava
RxJava is a lightweight open-source library, originally from Netflix, that makes it easy to compose asynchronous data sources and operations. This presentation is a high-level intro to this library and how it can fit into your application.
Reactive programming on Android
The document discusses reactive programming and how it can be used on Android. It explains that reactive programming uses observable sequences and asynchronous data flows. It introduces RxJava as a library for reactive programming that uses Observables to compose flows of asynchronous data. It provides examples of how RxJava can be used on Android to perform background tasks, handle errors and activity lifecycles, load images asynchronously, and create and transform Observables.

Cocoa heads testing and viewcontrollers
This document discusses strategies for testing view controllers and legacy code. It recommends extracting testable code, testing UI without the simulator, and keeping tests small and focused. Specific techniques covered include:
1. Making view controllers testable by sharing data sources and mocking dependencies.
2. Refactoring legacy classes to be more testable by avoiding direct property setting and reducing dependencies.
3. Writing tests that verify UI state without animations by waiting for expected views to load.
4. Keeping tests visible alongside code to emphasize their importance in maintaining quality code.
Programming with ZooKeeper - A basic tutorial
This document provides a tutorial on using ZooKeeper to implement basic distributed synchronization primitives like barriers and producer-consumer queues. It includes code examples for Barrier and Queue classes that extend a base SyncPrimitive class. The Barrier class allows processes to synchronize barrier entry and exit. The Queue class implements a distributed queue where producers can add elements and consumers can remove the oldest element. Both use ZooKeeper to coordinate access through ephemeral nodes and watches.

Lecture10
TCP sockets allow for communication between applications over the internet. A server creates a ServerSocket to listen for incoming connections on a specific port. When a client connects, the server accepts the connection to get a Socket. Both client and server then obtain input and output streams from the Socket to send and receive data. The connection is closed once communication is complete. Multithreading allows servers to handle multiple clients concurrently by spawning a new thread for each connection.
Taming Core Data by Arek Holko, Macoscope
The document discusses best practices for working with Core Data in iOS applications. It covers 9 steps: 1) setting up Core Data, 2) accessing the managed object context, 3) creating NSManagedObject subclasses, 4) creating fetch requests, 5) integrating networking, 6) using NSFetchedResultsController, 7) protocolizing models, 8) using immutable models, and 9) modularizing the code. The overall message is that Core Data code should be organized cleanly using small, single-purpose classes and protocols to improve testability, separation of concerns, and code reuse.
Servletand sessiontracking
This document summarizes key aspects of Java servlets including:
- The servlet lifecycle which includes initialization, service, and destruction phases.
- How servlets handle HTTP requests through methods like doGet() and doPost().
- How servlets can communicate with other components using various protocols beyond just HTTP.
- How servlet contexts allow servlets to share information and resources.
- How servlets can create, read, and modify cookies to maintain state across requests.

Indicate the functions of the agent process in a network operating sys.docx
Indicate the functions of the agent process in a network operating system?
Solution
Answer: In a network operating system, an agent process is involved in the following:
1. In interpreting user commands
2. In deciding whether to allow entry of an host to network services or not.
3. To maintain database of relations among user, remote host and task. For example, information about hosts to which access is allowed for each user, log-in details, nature of allowed tasks etc.
4. In file management including allowing access to files to users as per their authorization at remote hosts.
5. In mapping the textual host name to host address.
6. In maintaing its own directory structure.
7. In maintaining a fixed set of files, common uitlity procedures etc. available to the users of network.
8. May hide file naming and other local conventions from remote user, if required.
9. May provide an environment in which a directory entry can be made for all remote files being accessed by each interested user.

Instructions
Inherit the interface provided above.
The Queue is a generic data structure, so declare an LinkedList.
HINT: You should use the first entry or head of the LinkedList as the front of the queue.
HINT: You should use the last entry or tail of the LinkedList as the rear of the queue.
You must not use add(), remove(), or element() in the LinkedList object.
You must implement toString() first, format is the same as LinkedList.toString().
Incremental development, so test one method at a time.
Review the TestProgram to see what is tested by each test number, 1 through 7.

Auto-GWT : Better GWT Programming with Xtend
Presentation from GWT.create 2015 EU
Auto-GWT (auto-gwt.org) is a library for the Google Web Toolkit, that frees your code from unneccessary and complicated boilerplate and at the same time pushes the IDE capabilities to a new level. Auto-GWT is based on Xtend (xtendlang.org).
Xtend is a modern programming language that is 100% compatibly with existing Java libraries and even translates to readable Java source code. With it's slick syntax and powerful features such as lambdas, operator overloading and compile-time macros you can turn any verbose piece of Java code into a small and elegant piece of expressive Xtend code.
In this session we will show how Xtend can be used to program GWT applications and how well the typical GWT idioms are supported by the language.

Java concurrency
This document discusses Java concurrency. It begins with an agenda and then covers key topics like shared state, thread safety, concurrency problems and symptoms, and Java concurrency methods. Facts about processors, caches and memory interactions that can impact concurrency are presented. Examples are provided to illustrate concurrency issues like visibility and atomicity. Common concurrency problems like invalid states and their symptoms are outlined. Finally, Java concurrency methods like thread confinement, immutability, volatile variables, and synchronized are defined and code examples are shown.
EVERYTHING ABOUT STATIC CODE ANALYSIS FOR A JAVA PROGRAMMER
Static code analysis tools can analyze Java programs to find defects without executing the code. They use techniques like pattern matching, type inference, data flow analysis and symbolic execution. PVS-Studio is a static analysis tool for Java that was created using lessons from a C++ analyzer. It finds bugs like integer divisions by zero, dead code, copy-paste errors and other defects. Integrating static analysis into development processes helps improve code quality over time by detecting and fixing issues early.
Jdbc[1]
This document discusses using JDBC to access databases from Java applications like JSP pages. It covers loading the appropriate JDBC driver, establishing a connection with the database using a connection URL, executing SQL statements using Statement objects to retrieve and process result sets, and closing the connection when done. The core steps are to load the driver, get a connection, create statements, execute queries/updates, process results, and close the connection.

Java byte code in practice
At first glance, Java byte code can appear to be some low level magic that is both hard to understand and effectively irrelevant to application developers. However, neither is true. With only little practice, Java byte code becomes easy to read and can give true insights into the functioning of a Java program. In this talk, we will cast light on compiled Java code and its interplay with the Java virtual machine. In the process, we will look into the evolution of byte code over the recent major releases with features such as dynamic method invocation which is the basis to Java 8 lambda expressions. Finally, we will learn about tools for the run time generation of Java classes and how these tools are used to build modern frameworks and libraries. Among those tools, I present Byte Buddy, an open source tool of my own efforts and an attempt to considerably simplify run time code generation in Java.
Building Scalable Stateless Applications with RxJava
RxJava is a lightweight open-source library, originally from Netflix, that makes it easy to compose asynchronous data sources and operations. This presentation is a high-level intro to this library and how it can fit into your application.
Reactive programming on Android
The document discusses reactive programming and how it can be used on Android. It explains that reactive programming uses observable sequences and asynchronous data flows. It introduces RxJava as a library for reactive programming that uses Observables to compose flows of asynchronous data. It provides examples of how RxJava can be used on Android to perform background tasks, handle errors and activity lifecycles, load images asynchronously, and create and transform Observables.

Cocoa heads testing and viewcontrollers
This document discusses strategies for testing view controllers and legacy code. It recommends extracting testable code, testing UI without the simulator, and keeping tests small and focused. Specific techniques covered include:
1. Making view controllers testable by sharing data sources and mocking dependencies.
2. Refactoring legacy classes to be more testable by avoiding direct property setting and reducing dependencies.
3. Writing tests that verify UI state without animations by waiting for expected views to load.
4. Keeping tests visible alongside code to emphasize their importance in maintaining quality code.
Programming with ZooKeeper - A basic tutorial
This document provides a tutorial on using ZooKeeper to implement basic distributed synchronization primitives like barriers and producer-consumer queues. It includes code examples for Barrier and Queue classes that extend a base SyncPrimitive class. The Barrier class allows processes to synchronize barrier entry and exit. The Queue class implements a distributed queue where producers can add elements and consumers can remove the oldest element. Both use ZooKeeper to coordinate access through ephemeral nodes and watches.

Lecture10
TCP sockets allow for communication between applications over the internet. A server creates a ServerSocket to listen for incoming connections on a specific port. When a client connects, the server accepts the connection to get a Socket. Both client and server then obtain input and output streams from the Socket to send and receive data. The connection is closed once communication is complete. Multithreading allows servers to handle multiple clients concurrently by spawning a new thread for each connection.
Taming Core Data by Arek Holko, Macoscope
The document discusses best practices for working with Core Data in iOS applications. It covers 9 steps: 1) setting up Core Data, 2) accessing the managed object context, 3) creating NSManagedObject subclasses, 4) creating fetch requests, 5) integrating networking, 6) using NSFetchedResultsController, 7) protocolizing models, 8) using immutable models, and 9) modularizing the code. The overall message is that Core Data code should be organized cleanly using small, single-purpose classes and protocols to improve testability, separation of concerns, and code reuse.
Servletand sessiontracking
This document summarizes key aspects of Java servlets including:
- The servlet lifecycle which includes initialization, service, and destruction phases.
- How servlets handle HTTP requests through methods like doGet() and doPost().
- How servlets can communicate with other components using various protocols beyond just HTTP.
- How servlet contexts allow servlets to share information and resources.
- How servlets can create, read, and modify cookies to maintain state across requests.

Indicate the functions of the agent process in a network operating sys.docx
Indicate the functions of the agent process in a network operating system?
Solution
Answer: In a network operating system, an agent process is involved in the following:
1. In interpreting user commands
2. In deciding whether to allow entry of an host to network services or not.
3. To maintain database of relations among user, remote host and task. For example, information about hosts to which access is allowed for each user, log-in details, nature of allowed tasks etc.
4. In file management including allowing access to files to users as per their authorization at remote hosts.
5. In mapping the textual host name to host address.
6. In maintaing its own directory structure.
7. In maintaining a fixed set of files, common uitlity procedures etc. available to the users of network.
8. May hide file naming and other local conventions from remote user, if required.
9. May provide an environment in which a directory entry can be made for all remote files being accessed by each interested user.

Interpretation 102-4 in the AICPA Code of Professional Conduct calls f.docx
Interpretation 102-4 in the AICPA Code of Professional Conduct calls for differences of opinion between the controller and CFO to be first taken up with:
the CEO.
the board of directors.
the external auditors.
the SEC.
Solution
According to AICPA guideline code 102-4 requires that any financial interpretation should be made in such a manner that it does not represent misstatement of fact. In this connection very often differences in the opinion is observed among two or more members. such difference can be solved in the followng manner:
1. Members will sit together and discuss among themselves on the issue. If it is observed that interpretation properly reflect the fact without any misinterpretation and higher authority is of the same view, then it will be accepted. No changes are required.
2. If members are doubted on these points, then it should be referred to next higher authority. That authority must be within the organization.
In this problem difference in opinion has been observed between controller and chief financial officers. They belong to middle level.There next higher authority is members of board of directors. External auditors or SEC are not belonging to the organization. They are outside authority. Chief financial officer is responsible for financial planning, record keeping andreporting to higher authority. He is directly responsible to Chief executive officer or President of the company.
Thus in this case difference of opinion should be first taken up with CEO. Thereafter if required, it can be taken up with board of Directors.
Answer: Thus correct answer is CEO.

internet domain names are linked to trademark issues- Technology makes.docx
internet domain names are linked to trademark issues. Technology makes it easy to copy and distribute musiceand movies without paying royalties. Business conducted on the internet raise security and privacy issues. What legal concerns are raised by these issues?
Solution
Companies that are solely based on the internet to generate traffic and revenues are faced with an extraordinary amount of breaches. Copying and distributing violates many known laws such as property rights, copy right infringements, as well as many types of torts. Equally important is a breach of the system itself. This breach can and may cause numerous violations putting this company in non-compliance regarding federal codes and state statues. For example, if servers are accessed through an unauthorized fashion, the data stored within may be stolen, compromising property of the company as well as the copyrights to the original owners of that data. The major concerns that currently plague all internet functioning companies are unauthorized access to their networking infrastructure. Such access will greatly affect the company

Internet network management framework as consisting of three major par.docx
Internet network management framework as consisting of three major parts: MIB, SMI, SNMP. To what extent do you believe this constitutes a framework? Are additional parts needed? Why isn’t ASN.1 considered part of the framework?
Solution
In my opinion there major parts of the network management framework can be considered a framework because each serves as a component within the network itself, with this said there are no other parts needed. ASN.1, or abstract syntax notation 1, serves as a base for the SMI, SMI has an ample amount of data types to be thought of as a separate entity.
SMI(structure of management Information) This is a format used to define operations and variables related to objects in the MIB. SMI is more of a language then a structure and it is a language used to define the management information. A cogent language is needed to ensure that data is not vague. SNMP(Simple Network Management Protocol.) SNMP is a protocol used to manage the management communications between devices. This is the short version of SNMP in any case
ASN.1(Abstract Syntax Notation One) Is \". ..a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking
ASN.1 not considered part of the framework:
ASN.1 for SNMP, the group responsible for SNMP deviated from ASN.1 in various ways which make it impossible for general purpose ASN.1 Tools to fully handle SNMP MIBs. They not only use the withdrawn ASN.1 MACRO notation, but use it in such a way that even ASN.1 Tools which still support the obsolete ASN.1 MACRO notation cannot properly handle the MIB definitions. You need a special tool created specifically for SNMP MIBs to fully parse and handle them properly

international ECO 305 course- how does culture embrace globalization a.docx
international ECO 305 course.
how does culture embrace globalization and the economy ???
Solution
Globalization continues to be a divisive subject among political activists, academics, business leaders, and policymakers. Some look at the rapid economic and political changes taking place around the world and see injustice. Others observe these same changes and see progress. On both sides of the debate, however, much of the discussion takes place among elites. What do average citizens around the world think about the powerful global forces transforming their societies? Survey research suggests that most people embrace the idea of a globalized world, albeit cautiously.
The main economic premises of globalization are generally accepted in regions throughout the world. People tend to believe their countries will benefit from trade, free enterprise, and investment by foreign companies. These views are especially common in many of the world

International business is conducted outside of the home country- Natio.docx
International business is conducted outside of the home country. Nations represent cultural diversity, with unique values, metaphors, stereotypes, idioms and language. How will you deal with people from another country? How will you function effectively when visiting countries with distinctive cultures, such as Mexico, China, Russia, Japan, or Switzerland?
Solution
There is no culture-free theory of management. Managing other people is the responsibility
of people who, like everyone else, have been enculturated and socialized into a cultural
set of values and beliefs that governs their thinking, emotions, and behaviors. Like communication,
management is culture bound. Moreover, managerial perceptions regarding the
factors that lead to organizational success vary across cultures. Unfortunately, many U.S.
managers are ill equipped to handle overseas assignments. In fact, roughly 40% to 50% of all
U.S. managers sent abroad receive no formal cross-cultural training.
As a result, up to 40% of overseas assignments are unsuccessful. Although fostering competent intercultural
managerial skills represents an enormous challenge, the rewards of successful international commerce are extraordinary. Professor Philip Rosenzweig of Harvard University argues that successful cross-cultural
management depends on the abilities of managers to communicate effectively. Rosenzweig
points out that communication is especially important during the initial stages of a business
relationship. Depending on the culture, the process of building trust among business
partners may take days, weeks, or even months. Moreover, Rosenzweig asserts, this process
cannot be accelerated. Rosenzweig recognizes that many American managers prefer

Insight Communications Promotes employees with good technical skills i.docx
Insight Communications Promotes employees with good technical skills into supervisory positions and then teaches them leadership skills.Is this the vst way for the company to get supervisors to lead well?Why and why not
Solution
This is the best way for the company to get supervisors to lead well.
1) This is because the already skilled employees of the comapany are turned into supervisors.
2) They have a know-how of how work is done in the company.
3) They have better rapport(communications ) with other employess.
If instead of this a supervisor is hired as a completly new employee, he will then only have the leadership and management skills. He won\'t have technical skills like an internal employee of the company. This is a major demerit because a person is supervising othe employees who dosen\'t know about the technical work the employees are doing. How can he supervise them?
4) They have a technical know-how.
5) the will cost the company less to convert alredy existing staff to supervisor tha to hire a new one

Infrared radiation is also called IR- Describe how it is different fro (1).docx
Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes “wastes†energy. Give examples showing how IR is used in modern technology.
Solution
Infrared Radiation consists of electromagnetic waves with wavelengths ranging from 700 nm to 1 mm. These radiations cannot be detected by human eye. On the other hand, visible light consists of electromagnetic waves ranging from 380 nm to 700 nm. These radiations can be detected by human eye.
IR are also known as thermal radiations. All objects emit and absorb IR. The hotter the object, the more IR it will emit. Dark surfaces are good emitters of IR.
Some animals have the ability to sense IR, known as IR vision. These animals have specialised IR sensing organs known as pit organs. For example: snake, mosquitoes, bed bugs and vampire bats are kind of animals that uses IR sensing to track their prey or any potential danger approaching them.
Infrared radiations are associated with thermal energy. In most of the devices, emission of thermal energy is waste of energy. For example: a light bulb generates heat along with light energy on passage of electricity. Now this heat energy is not a useful energy and gets wasted in the environment.
Use of IR in Modern technology:
1. It is used in heat sensitive thermal imaging cameras. They are used to study heat patterns of humans and animals. They are also used as night cameras.
2. IR is used in gas monitoring and analyzing systems. These systems are used for testing air samples to see what gases are contained in that sample.
3. It is used in thermal imaging and thermal motion detection. Thermal imaging is used by firefighters to see where a burning building is too hot to safely enter. Thermal imaging is used for space imaging and to know the temperature of distant stars.

Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes “wastes†energy. Give examples showing how IR is used in modern technology.
Solution
basic differences are- The electromagnetic spectrum comprises all wavelengths of light from the very short (gamma rays) to the very long (radio waves). Both visible and IR light are near the middle of the spectrum
The wavelength of an electromagnetic wave is the distance between peaks (or troughs) of the wave. IR radiation has longer wavelengths than visible light.
The frequency of a wave is a measure of how many times the wave oscillates between its minimum and maximum amplitude in one second. The frequencies of IR waves are less than the frequencies of visible ligh

Is the ability of the human ear better or worse than the sonic capabil.docx
Is the ability of the human ear better or worse than the sonic capabilities of a CD quality audio system? What can a digital engineer take advantage of because of this fact? Name the four classes of coding methods. Identify whether each compression method is lossy or lossless: Morse Code_____Run Length Encoding_____JPEG_____Say the relative frequencies of four symbols in an alphabet are 1/2,1/4,1/8 and 1/8. What is the entropy (numerical value) of the alphabet? Suppose we want to compress two sound recordings, A and B that are in.WAV format and equally long. If the entropy of A is twice that of B, which recording has a greater amount of randomness? Which recording should we expect to be shorter in compressed form?
Solution
As already short answer provided for other questions except Q10, I am answering it.
10)
Relative frequencies of four symbols in an alphabet are, ½, ¼, 1/8, 1/8,
So P(1) = ½
P(2) = ¼
P(3) = 1/8
P(4) = 1/8
Entropy of the alphabet = H(P) = - [ P(1) logP(1) + P(2) logP(2) + P(3) logP(3)+ P(4) logP(4)]
= - [1/2log(1/2) + ¼ log(1/4) +1/8 log(1/8) +1/8 log(1/8)]
= - [(-0.150514998) + (-0.150514998) + (-0.112886248) + (-0.112886248)]
= 0.526802492

Solution
Yes your answer is right.
i) Half reaction represents either the anodic half or cathodic half reaction.Here the question is asked about half reaction in iron electrode. In the given cell, Fe is acting as cathode. Hence it should undergo reduction. your equation representing reduction of Fe 2+ to Fe is right.
ii) Ionic equation including state symbols is asked. Ionic equation is nothing but the overall cell reaction represented in ionic form. Simply it is combination of cathode half reaction and anode half reaction. In the given cell, Magnesium is the anode. It undergoes oxidation. i.e. Mg(s) to Mg 2+ by loss of two electrons. We have already seen the cathode half reaction of reduction of Fe. Combining these two half reactions we get the overall ionic reaction
Mg (s) + Fe 2+ (aq) --------> Mg 2+ (aq) + Fe (s)

Inorganic Chemistry - Wurtzite vs- Rock-Salt Structures Beryllium oxid.docx
Inorganic Chemistry - Wurtzite vs. Rock-Salt Structures
Beryllium oxide (BeO) prefers the Wurtzite structure type (typical of ZnS) while LiF prefers the rock-salt structure type (typical of NaCI). Why does this happen? Use the following terms/words in your explanation a) ionic radii b) chemical bonding
Solution
Beryllium oxide prefers wurtzite structure type whereas LiF prefers rocksalt type structure.
If we look all these elements, namely, Be, O, Li, and F falls in the second period of periodic structure. Atomic radius decreases from left to right in the periodic table. This is because of addition of an electron in the same shell of the atom which compresses the atom due to more attraction towarrds the nucleus. The electronegativity of elements increases from left to right since it is inverse property of atomic radii. Atomic radius of Be 2+ is less than Li + whereas atomic size of O 2- is more than F - . Moreover, LiF is ionic in natute due to coulombic interaction of highly electropositive atom (Li) and highly electronegative atom (F). On the other hand, BeO is having covalent character along with ionic character in their chemical bond. Thus, BeO prefers wurtzite structure type whereas LiF prefers rocksalt type structure.

Is it time for IPI to reconsider its salesforce organization by product line?
Solution
During the period from August 2, 1989, (date of incorporation) through March 1990, the Company was largely inactive. Since that time, the Company has been engaged principally in research and drug discovery programs and clinical development of a drug compound. On July 25, 1994, the Company acquired all of the outstanding Common Stock of ImmunoPharmaceutics, Inc. (\"IPI\") (now discontinued), a San Diego, California based company, in exchange for Common Stock of the Company. TBC consolidated the IPI operation into TBC in the first half of 1996 The Company is presently working on a number of long-term development projects which involve experimental and unproven technology, which may require many years and substantial expenditures to complete, and which may be unsuccessful. To date, other than small amounts of monoclonal antibody compounds and services produced and sold by ImmunoPharmaceutics, Inc. (\"IPI\") (now discontinued), the Company has not developed or sold any products, and no assurance can be given that the Company will be able to develop, manufacture or market any products in the future. In addition, no assurance exists that future revenues will be significant, that any sales will be profitable, or that the Company will have sufficient funds available to complete its research and development programs or market any products which it may develop. Accordingly, the Company is considered to be in the development stage as it has not to date derived significant revenue from its planned principal operations.

Indonesian lenders are the most profitable business in the world- The.docx
Indonesian lenders are the most profitable business in the world. The average return on equity is 23% more than double the 9% in the US. The main issue is he limited supply of official lenders, prompting an average interest of 16-20% for short term loans (BusinessWeek, 2/24/13). Some consider this a form of usury. Usury is an excessive or exorbitant interest charge. In order to prevent usury, and politicians trying to save the \"little guy\" from the clutches of the greedy \"money lenders\", Indonesian government steps in and sets the upper limits on what can be charged for loan to 18%. Today, market forces pushed the interest rate at 20%, only $10 million in loans were made but 32 million were demanded. Graph the loan market and show the impact of setting upper limits on interest rate. Please explain.
Solution
it happend because of the government intervention, according to this expanation it is obeserving that the Indonesian business entities are in need of funds and even there are some people, having with surplus funds.
becuse of the ceiling in interest the flow of funds declined into the market, if the situation runs for a long while it leads to create many problems.
the supply is lesser than demand of funds, so automatically the lenders seek high interest rates other wise they wont ready to lend their money at lesser interest rates.
