Human action recognition has wide range of applications in surveillance, human computer interaction, video indexing and video annotation. In this paper, a discrete cosine transform based features have been exploited for action recognition. First, motion history image is computed for a sequence of images and then blocked-based truncated discrete cosine transform is computed for motion history image. Finally, K-Nearest Neighbor (K-NN) classifier is used for classification. This technique exhibits promising results for KTH and Weizmann dataset. Moreover, the proposed model appears to be computationally efficient and immune to illumination variations; however, this model is prone to viewpoint variations.

MATLAB is used as Digital Image Processing tool for Objects and their Position Detection on the basis of Primary Color Space and then used as Primary Controller to navigate the robot about these positions. While Arduino is used as secondary controller to drive motors of robot to move towards the provided values of locations. Developed image processing algorithm, interfacing of Arduino and Wireless Camera with MATLAB are discussed in detail. Complete Control system is implemented and experimental results are obtained to verify Image Processing Algorithm.

This model is suitable to implement trigonometric equations in FPGA devices. Combinational Division Algorithm, approach to use floating point numbers and implementation of look-up tables to provide values of trigonometric function (cosine, inverse cosine etc) in Very High Speed Integrated Circuits Hardware Description Language is briefly introduced. Along the model, test bench waveform is generated for functional verification. Spartan 3 devices are used for implementation. Maximum delay and resource utilization are compared from accuracy point of view (value of up to how many decimal points are required).

From 2007 onwards, Businesses and consumers alike wonder each year if there will be enough electricity to go around. It continues throughout the year but the period of concern, referred to as times of “peak electric load”, is a real threat as the demand for electricity exceeds the supply. Results are blackouts, crippling businesses and household activities within a sector, city, state, and unquestionably in entire region. Load management is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. This can be achieved by direct intervention of the utility in real time. This paper discusses a management plan for distribution of electricity. The idea of the research is to create such a balance in the load distribution to avoid total shutdown in any region. Power is distributed in such a way that all users can at least enjoy basic
household devices in all times of the day without the use of personal energy producing (generators) and energy storing
(Uninterrupted Power Supply) devices. In this paper,systematic empirical investigation of data was performed. Moreover the
disadvantages of alternative energy devices are explored and alternates are identified

Initially, a sinusoidal wave with RMS voltage of 220V is applied and the acoustic noise originating from the ac motor is recorded. At the same time a sample of the input voltage and current is also recorded. Fourier analysis is done on the input voltage, current, and the acoustic noise samples. In addition, the input voltage, current, and acoustic noise of the ac induction motor, when fed from a square wave signal is also recorded and applied to Fourier analysis. The Frequency spectrum of the acoustic noise indicates which frequency is to be eliminated. Later, similar experiments are performed with conventional filters. The acoustic noise generated when the proposed filter is connected, is presented. Lastly, a comparison is presented where the effectiveness of the proposed filter response in established.

In an airplane the stability is defined in three angles i.e. pitch, yaw, and roll. The control pitch has been focused in this paper, for which the low cost optimal PD controller is designed and compares control result with uncontrolled ones. The percentage overshoot, steady state error, settling time, and rise time of Boeing Commercial Airplane are reduced and also analyses the results through root locus and frequency response. MATLAB/Simulink plays an important role in monitoring the results of designed controller.

This makes a long range transmission of small packets possible with lesser consumption of energy. Cooperative Yet Opportunistic Diversity Technique (COYOTE) is a research based project that aims at designing a reliable system to assist Radio Frequency Identification (RFID) for long range transmission. It becomes possible by merging RFID with some other communication system, like Global System for Mobile Communication (GSM). This paper presents conditions where RFID system would not cause performance degradation to GSM network, being integrated into the same.

The real time data is plotted on MATLAB and mathematical model is analysed, synthesize by simulation without and with PID controller provided by different inputs (like unit impulse, unit step. Ramp, parabola etc)

Electromyography (EMG) is detection of electrical potential or signals according to the contraction or expansion of Muscles. Contraction/Expansion of muscle generates the electrical potential of few micro volts. EMG controlled prosthetic hand are hardly ever available in Pakistan. The reason of this unavailability is its high price and lack of research. This paper presents the implementation of EMG controlled prosthetic hand. The purpose of this research is to design a low cost multifunctional microcontroller based EMG prosthetic hand. Functional prototype is working according to the design. More research work should be supported and carried
out, if this prototype has to be launched commercially.
