Importance of Video Conferencing Amongst all the methods of communication, the newest way of communication now days are through video conference. In this case you can establish communication through video seminar without going anywhere. It saves traveling time and money of organizing a costly seminar. . 1. Latest method of communication: The biggest advantage of this technology is that without incurring travel or other expenses we can meet people of remote locations. With the help of this technology

The problem becomes intense when there are many OBSS using the same channel. The wide range WLAN usage has caused “tragedy of commons” problem especially at public places. OBSS cause problems such as low efficiency, higher congestion and low data rate. OBSS is a problem for 802.11 when it is intended to use for applications which require QoS. EDCA does not solve this problem as it does not require other BSSs to coordinate. Admission control only solves bandwidth allocation problem within a single

responsible for programming the flow table in each switch and monitor these switches to observe each packet flow. The Microblaze processor, acting as attacker nodes plays the role of an outside network and transmits packets at different programmable rates to the SDN switch network using an array of packet drivers. The big picture showing the connection between different components is given in Figure 3.1. The chapter is divided into two main sections. Section 3.1 describes the details of hardware implementation

restricted to 4 Mbps to consider asset limits, for example, foundation traffic, for instance. The high edge β is situated to 50 s and the discriminating limit off is situated to 20 s. We arbitrarily select 10 distinctive YouTube features with differing bit rates, each with a greatest determination of 1080p and least length of 20 minutes. A complete assessment run comprises of 10 runs every feature and determination, each with a length of time of 1000 s. Amid the runs, the accompanying parameters are measured:

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

III.REGISTERS WITH MULTI BIT FLIP FLOPS The section describes that multi bit flip flops operation and how they will form. Fig 2 shows single bit storage flip flop of D type in which it contains master latch and slave latch. So it needs clk and clk’ signals. Figure 2 : Single bit storage flip flop The multi bit flip flop is forms by suitable merging of single bit storage flip flops. The multi bit flip flops are uses same clock signal. So number individual clock signals reduces and clock power

SIMD instructions from 128-bits to 256-bits whereas the original version was a 256 –bit extension using YMM registers, mostly the floating point instructions. In addition Haswell also had Intel’s Fused Multiply Add (FMA) which includes 36 FP instructions that performs 256-bit computations and 60 instructions for 128-bit vectors. Haswell also supports 15 scalar bit manipulation instructions [17] which consists of bit field manipulations such as insert, extract and shift, bit counting such as zero count

HOMEWORK – 2 1. The range of 16 bit two’s complement is -32768 to 32767 Excess notation is: -32768 to 32767 Unsigned binary range is: 0 to 65535 2. The larger format increases both the range of values that can be represented and the precision of large and small values. Processing data represented in a larger format requires more complex circuitry and more time for executing the codes. Either of them will slow the program execution. 3. An array is stored in a continuous sequential memory locations

Assignment Instructions: • Develop a routine to identify and remove stop words • Implement a porter stemmer to stem the tokens processed by your indexer routine. • Remove (do not process) any term that begins with a punctuation character • Determine the term frequency (tft,d) for each unique term in each document in the collection to be included in the inverted index. • Determine the document frequency (dft) which is a count of the number of documents from within the collection that each unique inverted

numbers that represents light intensities at various points or pixels. These pixels make up the images raster data. Image steganography typically uses 8-bit and 24 bit pixel image files[5].8 bit images are small in size (in KB) but during encoding it provides only 256 colors. 8- bit images uses gray scale color palette for example .GIF. 24-bit images offers large size, more
