H.264 is the advance video coding standard for the compression and distribution of a video content. It has larger complexity in order to satisfy the demand of high quality video at low bit rate. Moreover, it requires the effective implementation of all its internal blocks. In the paper, we focuses on the implementation of two important blocks for H.264 encoder. We propose low complexity design of quantization and Context Adaptive Variable Length Coding (CAVLC). The quantization process is responsible for scaling down the value of transform coefficients. CAVLC is useful for a bit stream generation and it is adopted from the concept of modified Variable Length Coding (VLC) technique. The efficient architectures are designed for quantization and CAVLC blocks to have parallel and pipeline data processing. They are implemented on Virtex 4 XC4VLX40 FPGA family using VHDL. The synthesized results are obtained with Xilinx ISE 14.2 and resource, device utilization and timing analysis are reported. The results are compared with related work that shows the better real time performance of both blocks.
H.264是用于压缩和分发视频内容的先进视频编码标准。为了满足低比特率下高质量视频的需求，它具有较大的复杂度。此外，它需要有效地实现其所有内部块。本文重点介绍了H.264编码器中两个重要模块的实现。我们提出了低复杂度的量化设计和上下文自适应变长编码(CAVLC)。量化过程负责缩小变换系数的值。CAVLC是由修改变长编码(VLC)技术的概念发展而来的，用于比特流的生成。为量化和CAVLC块设计了高效的体系结构，以实现并行和流水线数据处理。它们是在Virtex 4 XC4VLX40 FPGA系列上使用VHDL实现的。在Xilinx ISE 14.2中获得了综合结果，并报道了资源、器件利用率和时序分析。结果与相关工作进行了比较，表明两种模块的实时性能都更好。

We developed a component-oriented modeling approach for the design of communication protocols and distributed systems. The approach aims at the reuse of components represented by means of Unified Modeling Language (Uml) diagrams. Designs based on compositions of components have to formally be proved for correctness. In this paper we propose a verification approach by combining trace equivalence and model checking to verify UML-based designs of communication protocols. Our method consists of two steps. Foremost, the internal and external component behaviors are verified independently regarding their formal correctness. Thereafter the correctness and consistency of compositions is verified. This is achieved by generating the component adaptation path as traces during the composition. The requirements, i.e., safety and liveness properties, are formulated using linear temporal logic formulae. We apply the Spin tool as our model checking mechanism. For this, we present a method for automatically transforming the designs into Promela. We evaluate our approach for an example data transfer protocol as a case study.

This paper proposes an efficient algorithm for contrast enhancement to preserve the essential details of microscopic images of malaria infected blood using Gamma Equalization (GE). The central idea of this method is first, to convert the input color blood image into gray scale one, and then to calculate the range value for the γth order image of a gray scale image. The look-up-table (LUT) values are calculated and the gray scale image pixel intensity values are converted into LUT values which yield final contrast-enhanced image by retaining the essential details. We tested different values of gamma (γ). The value of γ = 0.8 yields maximum contrast enhanced image, which is very useful for image analysis and a computer aided diagnostic system for malaria. On comparison, GE is found to be better than Histogram equalization (HE), Imadjust (IA) and Contrast-limited adaptive histogram equalization (CLAHE) for microscopic blood images of malaria by using image quality measures: Absolute mean Brightness error (AMBE), Entropy and average luminance.

Edge detection is one of the prominent preprocessing stages in many image processing applications like Image Segmentation, Machine vision, Image Analysis and Feature Extraction etc. In order to get optimally true edge response in these applications, a particular edge detection technique shall be vulnerable to errors even when the input image gets contaminated due to presence of high frequency noise or become hazy due to blurriness. In this paper, a robust edge detection technique based on Back-propagation Neural Network with Multi-Thresholding, applicable on both Gray scale and Colored images, is presented. It is demonstrated that the proposed technique performs qualitatively and quantitatively better than Sobel, Robert's, Prewitt's, Canny and Neural based (without Multi-Thresholding) Edge Detectors under both Noisy & Blurred input conditions.

Synchronization of different types, control and regulation of chaotic systems are important areas of research in the control literature and various methods have been adopted for these research problems. Also, the discovery of novel chaotic systems in various applications, their qualitative properties and the control of such systems are also important research areas in chaos theory. This paper proposes a novel 3-D chaotic system and details its qualitative properties such as Lyapunov exponents and Lyapunov dimension. Next, the main result of this paper, namely, an adaptive feedback controller has been constructed for the drive-response synchronization of novel systems for all initial states when the system parameters are unknown. Phase orbits of the new chaotic system have been demonstrated using numerical simulations with MATLAB. Adaptive feedback results for the drive-response synchronization of the systems have been also illustrated using numerical simulations with MATLAB.

An Radio Frequency (RF) Power Amplifier (PA) plays a key role in front end of RF Transmitter. It's role is to convert low power RF Signal into high Power signal so that it can drive the antenna of the transmitter. The PA exhibits certain desirable characteristics such as enormous output Power, reduced heat dissipation, nominal input and output return loss and eminent gain. It is necessary to cut down Power consumption of PA, since PA depletes majority of Power at the transmitter. A two stage cascode topology based 0.18μm Complementary Metal Oxide Semiconductor (CMOS) PA with driver and power stages has been designed using Agilent Advanced Design System (ADS 2009) simulation tool. Here PA needs dc power supply of 1.8V and designed to operate at 2.4 GHz. Current mirror biasing is used at both the stages. The circuit uses source degeneration for input matching and tank circuit for output matching. Interstage matching is provided by a capacitor.
射频功率放大器(PA)是射频发射机前端的关键器件。它的作用是将低功率射频信号转换成高功率信号，从而驱动发射机的天线。该放大器具有一些理想的特性，如巨大的输出功率，减少的散热，标称的输入输出回波损耗和显著的增益。有必要降低PA的功耗，因为PA消耗了发射机的大部分功率。利用Agilent Advanced Design System (ADS 2009)仿真工具，设计了一种基于0.18μm互补金属氧化物半导体(CMOS)的两级级联码拓扑，具有驱动级和功率级。这里PA需要1.8V的直流电源，设计工作在2.4 GHz。在这两个阶段都使用了电流反射镜偏置。该电路采用源退化进行输入匹配，罐电路进行输出匹配。级间匹配由电容器提供。

Land based vehicles, i.e. cars, make up the main mode of transport on Earth, emitting harmful greenhouse gases due to combustion of fossil fuels. By installing regenerative systems in vehicles, the fuel consumption of the internal combustion engine (ICE) is reduced by capturing the energy usually lost during braking and reusing it to help propel the vehicle. The work described in this paper explores the practicality of a pneumatic regenerative braking system (PRBS). A functional prototype was successfully designed and tested to obtain efficiency data from a prototype.

The future user needs in the field of Multimedia retrieval is the focus of many research and development activists. It is empirically observed that no single algorithm is efficient in extracting all different types of images like building images, flower images, car images and so on. Hence a thorough analysis of certain color, texture and shape extraction techniques are carried out to identify an efficient CBIR technique which suits for a particular type of images. The Extraction of an image includes feature description, index generation and feature detection. The low-level feature extraction techniques are proposed in this paper are tested on Corel database, which contains 1000 images. The feature vectors of the query image (QI) are compared with feature vectors of the database images to obtain matching images(MI). This paper proposes Fuzzy Color and Texture Histogram (FCTH) techniques which extract the matching image based on the similarity of color and edge of an image in the database. The Image Retrieval Precision value (IRP) of the proposed techniques are calculated and compared with that of the existing techniques. The algorithms used in this paper are Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Fuzzy Linking algorithm. The proposed technique results in the improvement of the average precision value. Also FCTH is effective and efficient for image indexing and image retrieval.

In this paper a new MAC protocol called FAMAC is proposed. This protocol has been designed keeping in view the impact of both small scale and large scale fading environments. Whenever the transmission process encounters a small scale fading environments such as rayleigh or ricean, the action is taken to retransmit the RTS control signal expecting the improvement of the communication environment. In case of large scale fading, the transmission power is increased under the assumption that the communicating environment will remain approximately same in the near future. By using ns2 simulator, performance of FAMAC the proposed MAC protocol is compared with the two other most widely used MAC protocol DCF & EDCF. Avg. end-to-end delay and throughput are taken as the performance measure for the purpose. It was observed that the proposed FAMAC protocol shows improved results in comparison to DCF & EDCF. FAMAC shows higher throughput and lesser avg. delay in comparison to other MAC protocols. It was also observed that in FAMAC, the throughput and avg. and-to-end delay remains unaffected by various fading environment. But in DCF and EDCF, those are affected by Rayleigh and Ricean fading environment.

Also, the discovery of multi-scroll chaotic systems in various applications, and the control of such systems are important research areas in chaos theory. Yu four-wing chaotic system (2011) is a novel 4-D chaotic system with a positive Lyapunov exponent. This paper with the help of adaptive control design derives new results for the GPS of Yu four-wing chaotic systems when there is no knowledge of system parameters.
