The purpose of this project is to design and build a control system with an FPGA chip to control the movements of a robotic arm. The whole system is composed of the Controller System and the drive circuits, one driver circuit for each motor on the robotic arm. These drive circuits are needed because the Control System does not supply enough power to drive the motors directly. The controller System is implemented on the Spartan -II FPGA chip using VHDL code. Spartan -II FPGA is capable of running at much higher speed but a slow clock is needed to obtain relatively large delays for the output signals. This paper basically focus on the work of our project which is based on motion control using stepper motor .we have successfully done the basic part of project in which we control the stepper motor using FPGA. We have successfully done the programming and simulation part of the project. We enjoyed the PCB designing, soldering and troubleshooting of PCB. This project gives the idea regarding controlling servo and stepper motor using interfacing of ULN2803A with FPGA. Consequently, it's important to understand how to work, and what problems exist in designing effective robots. This project will address one of those problems: positional control.

An electronic nose is an instrument intended to mimic the human sense of smell. Electronic noses (e-nose) employ an array of chemical gas sensors, a sample handling system and a pattern recognition system. Pattern recognition provides a higher degree of selectivity and reversibility to the system leading to an extensive range of applications. These ranges from the food and medical industries to environmental monitoring and process control. Many other types of different gas sensors available. These include conducting polymers (CP), metal oxide semiconductors (MOS), piezoelectric, optical fluorescence, quartz crystal microbalance (QCM) and Amperometric gas sensors. The ideal gas sensor would exhibit reliability, robustness, sensitivity, selectivity and reversibility. High selectivity with high reversibility is difficult to attain. After signal processing and feature extraction the output of the sensors provide a unique “smellprint” for that substances which can be used to classify, measure concentration, or verify quality. The present paper illustrates the function of electronic nose, its application and investigates the effective use of e-nose in detecting gases that have some smell developed by the volatile organic compounds (VOC) like ethanol, acetone and benzene at different concentrations. The response and characteristics prove that the Electronic nose is a reliable instrument which can be used for environment control (air quality, pollutants, and gas emission levels), medical science (urine, skin and breath odour etc.), food industry (coffee, milk, soft drink fish, meat etc.), pharmaceutics, chemical industry, Defence and security industries (detecting humanitarian land mines etc.) and semiconductor industrial processes.

CDMA is interference limited multiple access system. Power control is an effective way to reduce co-channel interference. Consequently, it can improve the system capacity. CDMA employs fast closed-loop power control in uplink in which signal-to-interference ratio (SIR) is estimated. Transmitting power is adjusted by comparing estimated SIR with desired SIR. In this paper a modified fixed step power control algorithm has been proposed, which can improve the performance of a CDMA system. The proposed algorithm produced a faster convergence and low outage probability compared to other power control algorithms discussed and analyzed to maintain the desired SIR target.

The Set Partitioning in Hierarchical Trees (SPIHT) based color image coder, commonly referred as Color SPIHT (CSPIHT) are developed to quantize and encode wavelet coefficients and have excellent rate distortion characteristic in the noise free environments. However in presence of noise they are extremely sensitive to the bit errors. It was observed that bits have different degree of vulnerability of errors. The error in some of the bits (critical bits) causes the severe degradation while errors in other bits (non-critical bits) have negligible effect in the reconstructed images. In this paper, we propose an unequal error protection (UEP) scheme, in which within each bits plane, the bits are reorganized according to their sensitivity of errors and then critical bits are protected unequally using Rate Compatible Puncturing Convolutional (RCPC) codes. The protection is reduced for higher bit-planes, by changing the puncturing rate. The simulation results show an improvement of 5–15 dB in the quality of reproduced images, as compared to the equal error protection (EEP) and unprotected CSPIHT bit-stream.
基于分层树集分割(Set Partitioning in Hierarchical Trees，简称spieht)的彩色图像编码器，通常称为CSPIHT (color SPIHT，简称CSPIHT)，用于对小波系数进行量化编码，在无噪声环境下具有良好的率失真特性。然而，在噪声存在的情况下，它们对误码极为敏感。结果表明，比特具有不同程度的易出错性。某些比特(关键比特)的误差会导致严重的退化，而其他比特(非关键比特)的误差对重构图像的影响可以忽略不计。本文提出了一种不等错保护(UEP)方案，该方案在每个比特平面内，根据比特对错误的敏感性对比特进行重组，然后使用速率兼容刺破卷积(RCPC)码对关键比特进行不等错保护。通过改变穿刺率，对更高位平面的保护降低了。仿真结果表明，与等错误保护(EEP)和不受保护的CSPIHT比特流相比，再现图像的质量提高了5-15 dB。

Provision of quality of service (QoS) in todays Internet is an area that attracts the current state-of-the-art research. In this paper, we study the effect of topological and traffic variations on the provision of QoS using RSVP/ns. In our performance evaluation, we focus on the effect of varying packet size, number of flows, and mixing of best-effort flows with RSVP flows on the bandwidth reservations.

In this paper new partial encryption schemes are present, in which a secure encryption algorithm is used to encrypt only part of the images. Only part of the original data is encrypted for two different grayscale images and two color images of size (256 × 256) pixels, resulting in a significant reduction in encryption and decryption time.

Content based video indexing and retrieval traces back to the elementary video structures, such as a table of contents. Thus, algorithms for video partitioning have become crucial with the unremitting growth in the prevalent digital video technology. This demands for a tool which would break down the video into smaller and manageable units called shots. In this paper, a shot boundary detection technique has been proposed for abrupt scene cuts. The method computes cooccurrence matrices by taking block differences between the consecutive frames in each of R, G, and B plane, using sum of absolute differences (SAD). Feature vectors are extracted from the co-occurrence matrices' statistics, defined at various pixel displacement distances. The statistical find-outs are integrated into a training set and an unsupervised classifier, K-means, is used to identify the shot-frames and the non-shot frames.
基于内容的视频索引和检索可以追溯到基本的视频结构，如目录。因此，随着数字视频技术的不断发展，视频分割算法变得至关重要。这就需要一种工具将视频分解成更小的、可管理的单元，称为镜头。本文提出了一种针对场景突然剪切的镜头边界检测技术。该方法采用绝对差和(sum of absolute difference, SAD)的方法，取R、G、B各平面连续帧之间的块差来计算共发生矩阵。特征向量是从共现矩阵的统计量中提取的，这些统计量在不同的像素位移距离上定义。统计结果被整合到训练集中，并使用无监督分类器K-means来识别投篮帧和非投篮帧。

Electronic Control Units (ECUs) are widely used to improve the comfort and reliability of vehicles. It has become the fundamental building block of any automotive subsystem and is interfaced with electro mechanics counterpart. To meet the system wide requirements, these ECUs are interconnected using the communication infrastructure. Although the communication infrastructure in terms of, predominantly, the CAN based vehicle network took its birth to enable ECUs to work in a coordinated manner in order to support system wide requirements, during the past decade, this infrastructure was also viewed as a potential means to incorporate extensibility in terms of addition of newer ECUs which are built for implementing additional requirements. With this paradigm, the number of ECUs started growing in a steep manner, uncontrolled and as a result, today, it is not hard to see a high segment automotive housing ECUs as large as 75–80. Hence, load balancing mechanisms are needed to ease ECU integration and for efficient utilization of CPU power in ECUs. In this paper, we explain the concept of load balancing on the basis of CPU utilization across ECUs.

In this paper we adopt FFT based fractal analysis method. With the help FFT based method breast tumors (benign and malignant) are classified based on their shapes. In general malignant tumors contour have rough and irregular shapes whereas benign contour have smooth and macrolobulated shapes. In this paper we present a fractal based Fourier transform method to classify the contours. The log -log magnitude frequency response plot and rose plot (for average radial distance and angle variations in terms of average slops and slope of intercept) are used in this study in order to extract the features for classifications.

The paper presents a new Multi Inputs and Single Output (MISO) VM Universal Biquadratic Filter (UBF) employing only two low voltage dual output current conveyors (DOCCIIs) along with two resistors and two capacitors. The proposed circuit realizes six standard biquadratic responses, viz., low pass high pass, non inverting band pass, inverting band pass, band elimination and all pass. The filter enjoys attractive features, such as, low active and passive component count, low sensitivity performance, operation of low supply voltage (± 0.75V) and power consumption of 3.2mW. The filter was designed and verified using PSPICE with convincing results.
