Abstract: VLSI based Accident information and car security system deals with the concern of saving the victim ‚ who get trapped in accident and also about the car security. Accident of the car is detected using pressor sensors which are fixed in car. Accident information to the nearest hospital is carried out with the help of RF communication. The location of the car is found using the GPS technique. The security of car is ensured by using password. The theft information is sent to the owner’s mobile

procedure to determine how many times the divisor D divides the dividend B thus resulting in the quotient Q. At each step in the process the divisor D either divides B into a group of bits or it does not. The divisor divides a group of bits when the divisor has a value less than or equal to the value of those bits. Therefore‚ the quotient is either 1 or 0. The division algorithm performs either an addition or subtraction based on the signs of the divisor and the partial remainder. There are number

saying "no‚ you first". The Media Access Control sublayer also determines where one frame of data ends and the next one starts – frame synchronization. There are four means of frame synchronization: time based‚ character counting‚ byte stuffing and bit stuffing. The time based approach simply puts a specified amount of time between frames. The major drawback of this is that new gaps can be introduced or old gaps can be lost due to external influences. Character counting simply notes the count of

Arithmetic and Logical Operations Chapter Nine There is a lot more to assembly language than knowing the operations of a handful of machine instructions. You’ve got to know how to use them and what they can do. Many instructions are useful for operations that have little to do with their mathematical or obvious functions. This chapter discusses how to convert expressions from a high level language into assembly language. It also discusses advanced arithmetic and logical operations including multiprecision

computer are divided into thousands of tiny compartments called bits. Each bit has an electronic switch or gate. On means the gate is open and letting electricity go through. The computer reads on or open switches as a number 1. Closed gates are off because the electricity is blocked and cannot get through. The computer reads off bits as 0. It is by grouping these bits together to form a series of 1/0 commands‚ that data is formed. Eight bits are grouped together to form a byte. In this group of eight

the disturbances of correlations between colour components (Li‚ B. and He‚ J. 2011). There are various techniques used for Image steganography which are performed on various formats of images. Some of the techniques include: Least Significant Bit technique – In this method‚ the image is scanned row wise and it is encoded in binary. Then‚ the message is also encoded in binary. The image size and the message size are compared. Once done‚ a random pixel from the image is chosen and is divided into
