Data Compression Essays - Archive Formats, Data Compression

Data Compression Essays - Archive Formats, Data Compression Data Compression subject = Information Theory title = Data Compression Data Compression- in beginners terms Data Compression just sounds complicated. Dont be afraid, compression is our good friend for many reasons. It saves hard drive space. It makes data files to handle. It also cuts those immense file download times from the Internet. Wouldnt it be nice if we could compress all files down to just a few bytes? There is a limit to how much you can compress a file. How random the file is, is the determining factor to how far it can be compressed. If the file is completely random and no pattern can be found, then the shortest representation of the file is the file it self. The actual proof that proves this is at the end of my paper. The key to compressing a file is to find some sort of exploitable pattern. Most of this paper will be explaining those patterns that are commonly used. Null suppression is the most primitive form of data compression that I could find. Basically, it says that if you have different fields that data is in (possibly a spread sheet), and any of them have only zeros in them, then the program just eliminates the data and goes straight from the empty data set to the next. Only one step up from null suppression is Run Length Encoding. Run length encoding simply tells you how many of what you have in a row. It would change a set of binary data like 0011100001} into what the computer reads as (2)zeros, (3)ones, (4)zeros, 1. As you can see, it works on the same basic idea of finding a series of 0s (null suppression) and 1s in this case too and abbreviating them. Once the whole idea of data compression caught on, more people started working on programs for it. From these people we got some new premises to work with. Substitutional encoding is a big one. It was invented jointly by two people: Abraham Lempel and Jakob Ziv. Most compression algorithms (big word meaning roughly program) using substitutional encoding start with LZ for Lempel-Ziv. LZ-77 is a really neat compression in which the program starts off just copying the source file over to the new target file, but when it recognizes a phrase of data that it has previously written, it replaces the second set of data in the target file with directions on how to get to the first occurrence of it and copy it in the directions place. This is more commonly called a sliding-window compression because the focus of the program is always sliding all around the file. LZ-78 is the compression that most people have in their homes. Some of the more common ones are ZIP, LHA, ARJ, ZOO, and GZIP. The main idea behind LZ-78 is a dictionary. Yet it works quite a bit like the LZ-77. For every phrase it comes across, it indexes the string by a number and writes it in a dictionary. When the program comes across the same string, it uses the associated number in the dictionary instead of the string. The dictionary is then written along side the compressed file to be used in decoding. There is a combined version of LZ-77 an LZ-78. It is called LZFG. It only writes to the dictionary when it finds the repeated phrase, not on every phrase. Then instead of LZFG replacing the second set of data with directions on how to get to the first occurrence of it, the program puts in the number reference for the dictionarys translation. Not only is it faster, but it compresses better because of the fact that it doesnt have as big of a dictionary attached. Statistical encoding is another one of the new compression concepts. It is an offshoot of the LZ family of compressors; It uses basically the same style as LZFG, but instead of assigning the numbers in order that the strings come out of the source file, statistical compressors do some research. It calculates the number of times each string is used and then ranks the string with the most number of uses at the top of the hash table. The string with the least is ranked at the bottom. (A hash table is where the rank is figured) The higher up a string is on this list, the smaller of a reference number it gets to minimize the total bit usage. This gives this compression just a slight edge on the others, but every little bit helps. (ha ha -bit- ) Beware! There are a

The Features Of The Education Of Children With Autism Essay - 1

The Features Of The Education Of Children With Autism - Essay Example When playing or cooperating with others, he imagines goals and objectives differently, and one of the few ways that he is mean or uncooperative with his fellow classmates is when he views them as â€Å"stupid† because they don't share his perspective on the game or its objectives. He is very rational in some ways, struggling to understand how others make emotionally motivated or social decisions. Adam B. does very well in art, geometry, science, and math getting As and Bs very easily and wondering why others find it so hard. He fails to understand how they can be doing badly at these tasks. Meanwhile, he struggles to get above a C in history, English, and other classes, though he has managed to keep his grades high. The material does not resonate with him, and he finds it very hard to do anything besides keeping dates and places straight: He finds it difficult to understand motivations in stories and history. He is competent in music but he doesn't understand what others experience when they listen to it: He views music exclusively as a way to calm him and doesn't like the noise. In physical education, he is poorly coordinated but very strong and doesn't know how to coordinate his own strength. He is larger than most of his classmates, being in the 80th percentile of height. His social strengths are that he is very nice, helpful to others, and tries to greet others warmly. His academic strengths are in rational, logical, ordered tasks that do not involve understanding motivations or theories. However, he gets very impatient with others. He struggles to make eye contact, and when he is nervous, he does repetitive behaviors that distance him from others: He mutters a nonsense language under his breath and plays with his fingers, tapping them against each other and shaking them rhythmically. He acts up when there is too much noise or activity, and finds it hard to play with others when they are being too loud.

Rita Dove Roast Possum What is Thomas Doing Essay

Rita Dove Roast Possum What is Thomas Doing - Essay Example He tells stories about a special horse and also about hunting possums. These are kind of folk stories, but the children love the stories because the evoke a distant time when the world was a different place. Part of the context of this different time is that African-Americans would not have been treated as proper people. Behind Thomas is an encyclopedia. Encyclopedias are supposed to be repositories of knowledge. They are supposed to be just the facts. But we can see that this book has racists facts such that African-American children stop being intelligent when they reach puberty. It is clear that the stories that the book tells are less true than the stories that Thomas is remembering of his youth. The encyclopedia is an official book which is full of so-called facts. Thomas's story is full of lingo and second-hand information, but Dove is implying that nevertheless Thomas's stories are much more true than the books, even if there are dozens of them fulling the shelves. These kind of stories, Dove is saying, tell us a lot about ourselves (Righelato, 87). Thomas' stories have embellishments but that only makes them more true, the poet suggests. They are full of old-time know how, which beats academic knowledge any day, Dove implies. When Malcolm asks Thomas about the horse, Thomas replies with more details about the possum.

The Existing System For Payslip Generation

The Existing System For Payslip Generation The purpose of the proposed project is to automate the Payslip generation process which replaces the traditional system of Payslip generation that used to print the employee salary details onto a paper. This project includes a single user who is authorized to initiate the application. The privileges are given only to the individual in a department who is responsible for generating the PaySlips for the employees. The application takes in the Excel Spreadsheet as input and generates an encrypted PDF PaySlip for each employee. This PDF PaySlip is mailed to the respective employee by using their mail-id which is provided in the Excel sheet. This application generates PaySlips of each employee every month. The PaySlip spreadsheet is uploaded to the system. The application uses an excel parser to read this spreadsheet. The excel parser parses the excel sheet in a row-wise fashion and generates an xml string for each row. This xml string contains the salary data of each employee. The salary data is converted into a password-protected PDF document as per a pre-defined template. These salary statements (in PDF) are emailed to respective users. The email process is logged. 1.2 Existing System: The existing System for PaySlip generation includes manual entry of the pay details of all the employees in an excel sheet and converting them to word document. Each row from the excel sheet is taken and then converted into the word document. This word document contains the Pay details of the employee. This document is printed on to a paper and then distributed to all the employees. The Existing System requires manual effort in converting the excel sheet data into the word document. The word document which contains the salary details should be generated for all the employees which in turn delays the whole process of distributing the payslips. As the paper is used in distributing the payslips this even includes the wastage of paper. This is till the part of generation of pyslips itself. When talking about distribution each and every paslip has to be signed by the authority, stamped and then folded which is placed in the envelope.this has to be distributed to all the employees near the desk has to take an acknowledgement that the employee has received by signing on paper. If the employee is not at the desk or out of station then distribution has to be postponed for that employee till he is available. That is he cant check it immediately after its been issued. Making it remotely accessible is also another aspect of it. 1.3 Proposed System: The proposed System for generating the PaySlips is a Web based Automated System for generation and distribution of PaySlips. Proposed System is efficient enough as it includes Less Manual effort. Manual effort is needed in only logging into the application and uploading the appropriate excel sheet into the application. Just a click on the upload button is sufficient, then the application itself will generate the payslips and distribute them to the respective employees mailid. Optimal performance of the application is achieved as delay is reduced in generation of Payslips with the existing system. Paper conservation is achieved, as the PaySlips are sent to the employees through mails, This makes the payslip remotely accessible 2.1 Functional Requirements Modules: Authentication/Authorization Upload File Excel Parser PDF Generation Email Module Description: Authentication/Authorization Module: This application is used to generate payslips of the employees for every month. Payslips, that depict all the salary details, is very confidential and hence this work should be carried out by an authorized person. For this purpose the user is presented with a login and is granted access to the application only after supplying a valid username and password. This needs database connectivity that stores all the details of the users who can use the application with their password. This module is implemented using Struts. As this partitions the presentation and implementation the login UI is built using Java server pages. When the user submits the user name and password the servlet gets invoked handling the process that connects to the database, verifies and accordingly an action is taken that forwards to another UI. Upload File: This module uploads the Excel spread sheet into the application in which details of all the employees are present with the present months salary details. The details of the employee includes the name, empid, designation etc .The Excel spread sheet that is needed to be uploaded should be in a specified format i.e., all the details should be in the same chronological order according to the specifications. The uploaded spread sheet will not be saved any where as the data in the Excel sheet is very confidential. This module is implemented using Struts. The File Upload UI is built using Java server pages. When the user uploads an Excel file a servlet gets invoked handling the process that directs an action. Excel Parser: This module takes the uploaded excel sheet as input and parses it in a row wise fashion, organizes the data in xml format For this a special software tool is used In this module we also retrieve the employee-id, mail-id and month for which the payslip is generated. The software tool used for parsing the Excel document is POI. This needs a POI.jar added in the library where some predefined methods are defined. The POI consists of APIs for manipulating various file formats based upon Microsofts OLE 2 Compound Document format, and Office OpenXML format, using pure Java. In short, you can read and write MS Excel files using Java. In addition, you can read and write MS Word and MS PowerPoint files using Java. POI is your Java Excel solution (for Excel 97-2007). However, we have a complete API for porting other OLE 2 Compound Document formats and welcome others to participate. OLE 2 Compound Document Format based files include most Microsoft Office files such as XLS and DOC as well as MFC serialization API based file formats. Office OpenXML Format based files include the new (2007+) xml based file formats, including Microsoft office files such as XLSX, DOCX and PPTX. PDF Generation: This module creates a PDF file per employee based on pre-defined template and a randomly generated Password is used to encrypt the PDF file. This password is used by the employees to retrieve the PaySlips. The template is designed using XSL independently and values are taken from the Excel and filled into PDF using java. The PDF is encrypted using a random generated password and the password is attached to the mail. The encrypted PDF document is mailed to the employee. The software tool used for generating a PDF document is XSL-FO. XSL-FO is a language for formatting XML data . XSL-FO stands for Extensible Stylesheet Language Formatting Objects . XSL-FO is a W3C Recommendation . XSL-FO is now formally named XSL . XSL-FO is an XML-based markup language describing the formatting of XML data for output to screen, paper or other media. Styling is both about transforming and formatting information. When the World Wide Web Consortium (W3C) made their first XSL Working Draft, it contained the language syntax for both transforming and formatting XML documents. Later, the XSL Working Group at W3C split the original draft into separate Recommendations. XSLT, a language for transforming XML documents . XSL or XSL-FO, a language for formatting XML documents. XPath, a language for navigating through elements and attributes in XML documents. This is more advantageous because this seperates the presentation or template of the PDF and the implementation how the data is filled in. Email Module: This Module emails the Payslips (Password protected PDF files) to the respective employee by using their mail id. The mailing details are saved in a batch log with the time and date at which the mail is sent to the employee for verification. This module sets the mail attributes like the subject, from_address, to_address and message body. Also a partial random generated password is sent in the mails which need to be personalized by the employee. This module also inserts values into the email log with the details of mailing. The Protocol used for mailing the PDF document to a particular employee is SMTP. The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications.This is binded with Simple Mail Transfer Protocol for mailing. 2.2 Non-Functional Requirements Accessibility This application is easily accessible by the user who is authorized to use the system for generating PaySlips every month. Performance This system can generate PaySlips for any number of employees considering the same speed. Reliability This system is consistent and performs required functions under stated conditions. Security Unauthorized access to the system and its data is not allowed. The person who wants to access the system is authenticated against a username and password. The PaySlip mailed to the employee is also password protected. This ensures unauthorized access of the PaySlip. Usability This system enhances usability by incorporating well structured user interfaces, end-user interactions, informative error messages etc. 2.3 System Requirement Specification: Software Requirements: Language: Java/J2EE Operating system: Win 2000/XP or higher Web Server: Apache Tomcat Server Excel Parsers: POI(Poor Obfuscation Implementation) PDF Generator Tools: XSL-FO(Extensible Style sheet Language-Formatting Object) Back End: MySQL Database Hardware Requirements: Processor: P4 or higher RAM: 1 GB or higher Hard disk: 10 GB 3.1 Technical Architecture A Technical Architecture breaks down operational (business) processes into functional components and capabilities. It describes the structure and behaviour of the technology infrastructure of an enterprise, solution or system. The following diagram depicts functional components of the application. Browser Web Container (Tomcat) MySQL PaySlip Generation System The web container in detail handles the following operations as depicted in the following diagram As the web container receives the request from the browser it invokes the parser functionality and does the excel parsing row-wise and generates an xml String. The string data is used in generating the PDF. These PDFs which are generated are mailed to the respective employees by the mailer component. The entire email process is logged in a file. Once the application is deployed in the server we can access it locally or from remote using public IP or giving some domain name to the application. 3.2 Software Architecture Software architecture alludes to the overall structure of the software and the ways in which the structure provides conceptual integrity for a system. In the simplest form software architecture is the hierarchical structure of program components (modules), the manner in which these components interact and structure of data that are used by these components. The software architecture of a program or computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships between them. 4.1 Design Objectives: Design is the first step in the development phase of a process or system in sufficient details to permit its physical realization. Without design specifications, the design will be unguided. It is difficult to know when the process is complete and to measure the progress. Design is used to plan what information needs to be displayed and entered and how it relates to other information. Design is the only way to translate the requirements into a finished system. A well designed program will be easier to implement, distribute and maintain. 4.2 UML Diagrams 4.2.1 Usecase Diagram: 4.2.2 Class Diagram: 4.2.3 Sequence Diagram: 4.2.4 Collaboration Diagram: 4.2.5 Activity Diagram: 4.3 Data Flow Diagrams: Level 1 4.4 Database Design: 4.4.1 E-R Diagrams 4.4.2 Database Tables: Database Tables: 5.1 Pseudo Code Login Module Login form: public class LoginForm extends ActionForm { /**Declare two string variables that holds the username and password values entered in the form Define getter and setter methods **/ } Login Action: public class LoginAction extends Action { Public ActionForward execute(ActionMapping mapping, ActionForm actionForm, HttpServletRequest request, HttpServletResponse response) throws Exception { /**Create an object to the login form Retrieve the username and password entered in the form and save in some variables Create an object for the implementation and call the function validate() with the retrieved username and password as arguments Savetoken() Depending on its return value forward the action to success page or failure page**/ } Login Interface: public interface LoginDAO { /**Declare th method validate(string , string)**/ } Interface Implementation: public class LoginDAOimpl extends BaseDAO implements LoginDAO { Constructor() { } Validate () { /**Declare two string variables that holds the values of the username and password from he database Get the connection to the database using the predefined method in java Retrieve the username and password from the database using a SQL query(select) Compare both username, password from form and database Return a Boolean value according to the comparision**/ } } Login.jsp: CTE Pay Slip Generation System Employee Login function validateLogin(){ if(document.loginForm.username.value!=""&& document.loginForm.password.value!="") { return true; } else { alert("Please Enter UserName and Password."); return false;} } Login UserName : Password : Copyright  © 2009 Cambridge Technology Enterprises.

Life of Rabindra Nath Tagore Essay

Tagore’s international travels also sharpened his opinion that human divisions were shallow. During a May 1932 visit to a Bedouin encampment in the Iraqi desert, the tribal chief told him that â€Å"Our prophet has said that a true Muslim is he by whose words and deeds not the least of his brother-men may ever come to any harm †¦ † Tagore noted in his diary: â€Å"I was startled into recognizing in his words the voice of essential humanity. [1] In his last decade, Tagore compiled fifteen volumes of writings, including works of prose-poems such as Punashcha (1932), Shes Saptak (1935), and Patraput (1936). He also continued his experimentations by developing prose-songs and dance-dramas, including Chitrangada (1936), Shyama (1939), and Chandalika (1938). He also wrote the novels Dui Bon (1933), Malancha (1934), and Char Adhyay (1934). Tagore also took an interest in science in his last years, writing Visva-Parichay (a collection of essays) in 1937. He wrote on topics ranging from biology to physics, and astronomy; meanwhile, his poetry — containing extensive naturalism — underscored his respect for scientific laws. He also wove the process of science (including narratives of scientists) into many stories contained in such volumes as Se (1937), Tin Sangi (1940), and Galpasalpa (1941). [2] [edit]Illness of 1937-1941 Tagore’s last four years (1937–1941) were marked by chronic pain and two long periods of illness. These began when Tagore lost consciousness in late 1937; he remained comatose and near death for an extended period. This was followed three years later in late 1940 by a similar spell, from which he never recovered. The poetry Tagore wrote in these twilight years are distinctive for their preoccupation with death; these more profound and mystical experimentations allowed Tagore to be branded a â€Å"modern poet†. 3] After extended suffering,[4] Tagore died on August 7, 1941 (22 Shravan 1348) in an upstairs room of the Jorasanko mansion in which he was raised. [5] This date is still mourned in public functions held across the Bangla-speaking world. The last person to see Tagore alive was Amiya Kumar Sen (brother of Sukumar Sen, the first chief election commissioner); Tagore dictated his last poem to Sen, who wrote it down. Sen later donated the resulting draft to a museum in Kolkata.

MUSIC ANALYSIS: Changes by Tupac Shakure nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; For most people that listen to music, a song can be classified as simply a plethora of words constructed into verses in the midst of an appealing tune playing in the backdrop. But it is when an artist can take all of this and add even more to it to make it memorable and even sometimes controversial he or she is considered a great artist. Perhaps one of the most misunderstood rap, along with hip hop artist of the 20th century is the late Tupac Shakure. ...

Tupac has released around 15 albums and an uncountable amount of underground tracks. I have chosen to look at one of Tupac’s song that I think is the most concentrated on Black and White race relations in America. This song is called Changes, this song was released on his Greatest hits CD in 1998. In this song Tupac addresses this issue he begins the second verse with the lines; â€Å"And still I see no changes all I see is racist faces†¦.† (verse2). This verse is very powerful in that it addresses political racial issues, society’s justice system and how things in society are set up in a way that blacks will remain at the bottom of society and how that is accepted as the norm. He addresses in this verse the American presidency and how we aren’t ready to see a black man occupy the white house. Tupac says â€Å"we aint ready to see a black president†¦..huu† (verse2) I interpret this as him using sarcasm in that he laughs at the end and uses the term â€Å"we† when in all reality he knows that the majority of blacks in the U.S. are patiently waiting for that day. In his first verse Pac also addresses the law enforcement issues based on racial inequalities in our society.
