1. INTRODUCTION

The Universal Asynchronous Receiver/Transmitter (UART) controller is the key component of the serial communications subsystem of a computer. The UART takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Serial transmission of digital information (bits) through a single wire or other medium is much more cost effective than parallel transmission through multiple wires. A UART is used to convert the transmitted informa ....etc

Introduction Caeser Cipher

So this is Matlab code for Caesar Cipher Encryption and Decryption.There are many security techniques like Cryptography .The technique which was used in the past days is very simple and easily breakable in its method first a secret key is choosed after choosing key it added to every bit of data for example our data is Data = Attend meeting at noon and Encryption key = 3 so key is of single bit its mean its easily breable in 2.5ms So Now A = C , T = W , E=H , N=Q , D=G , M ....etc

Neuroscientist Paul Bach-y-Rita hypothesized in the 1960s that we see with our brains not our eyes. Now, a new device trades on that thinking and aims to partially restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain.

Legal blindness is defined by U.S. law as vision that is 20/200 or worse, or has a field of view that is less than 20 degrees in diameter. The condition afflicts more than one million Americans over the age of 40, according to ....etc

The file system must be user friendly as far as possible. Hence the operation on the system by tfie costumers must be limited. Thus the procedure for a search can be settled as follows. 'First of all the system displays a message Search:- to the costumer. The costumer must enter the first few letters of the name of the tram or the product or the patient. Then he must close the enter hey. Then the soft key 'FT' can be keyed to start the search. The system displays the details of if any match occurs. The Tsc %ey can 6e ....etc

INTRODUCTION
UNICODE
Unicode provides a unique number for every character,
no matter what the platform,
no matter what the program,
no matter what the language.
Fundamentally, computers just deal with numbers. They store
letters and other characters by assigning a number for each one. Before
Unicode was invented, there were hundreds of different encoding systems
for assigning these numbers. No single encoding could contain enough
characters: for example, the European Union alone requires several
diffe ....etc

A Signature-free Buffer Overflow Attack Blocker





Abstract:-

This project propose SigFree, a realtime, signature-free, out-ofthe-box, application layer blocker for preventing buffer overflow attacks, one of the most serious cyber security threats. SigFree can filter out code-injection buffer overflow attack messages targeting at various Internet services such as web service. Motivated by the observation that buffer overflow attacks typically contain execu ....etc

ABSTRACT
In this paper, several low power techniques, including low transition ASCII (LT-ASCII), that are particularly effective for the universal asynchronous receiver / transmitter (UART) circuits are proposed. Low power techniques, such as voltage scaling, clock gating, MT-CMOS and complete power shut down, are investigated to minimize the UART logic power in both continuous and idle modes of operation. The overheads circuitry required for each technique and penalties as ....etc

ABSTRACT
Most of the Indian language electronic data are Unicode encoded. Processing Unicode data is quite straight forward because it follows distinguished code ranges for each language and there is a one-to-one correspondence between characters. Hence it becomes necessary to identify the font enc ....etc

REPORT PROGRAMS CODE GENERATOR TOOL
PROJECT OVERVIEW
About the project
An automated code generator will enforce common structure for all batch programs conforming to a specific logic. It will generate the maximum possible program code based upon few user inputs. This generator will also help in reducing coding time of programmers and increase the efficiency by allowing programmers to focus on the application logic. This implies a great reduction in development costs. This will also ensure ease of c ....etc
