In this paper the transmitter intelligently adapts the transmission parameters like coding scheme, modulation symbol, power etc. w.r.t the varying wireless CSI. If channel is having poor transmission conditions then a channel code with smaller code rate and a smaller modulation symbol can be used. Similarly, if channel conditions are good, a comparatively high code rate or even no coding need be used. Paper gives an overview about the WiMAX standard and studies the performance of a WiMAX transmitter and receiver.

Industrial automation is the use of machines, control systems and information technologies to optimize productivity in the production of goods and delivery of services. The correct incentive for applying automation is to increase productivity, and/or quality beyond that possible with current human labor levels so as to realize economies of scale, and/or realize predictable quality levels. In the scope of industrialisation, automation is a step beyond mechanization. Whereas mechanization provides human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements while increasing load capacity, speed, and repeatability. Generally PLC Is used for the task of industrial automation, here we introduce new concept in automation is use of “Embedded PLC”for the industrial automation which overcome all the limitation of conventional PLC. For the purpose of automating some task we use neumerous wired or wireless sensors with Embedded PLC. It provide smooth control over the Industrial Systems. After investigated the conception and features of PLC and embedded system, in this paper the development of low-cost embedded PLC for Industrial Controls & Monitoring. This paper describes the real-time industrial automation using Embedded PLC.

This paper presents the effective approach to harness electrical energy from the highways by means of vertical axis wind turbine. The wind turbine consists of stationary shaft which is mounted on the ball bearing on top and bottom end of the shaft. In addition, dynamo is connected to upper and lower part of the wind turbine. As the vehicles are moving at faster rate on two different directions in highways, the wind turbine, which is placed on the highways sides, is able to rotate effectively on its own axis in any of the direction. As a result, the large amount of electrical energy gets generated in both day and night time. This wind power generation is an alternative way for power generation instead of depleting non-renewable energy sources.

The proposed work gives a method of cancer diagnosis using artificial intelligence. The method involves the use of MRI images which are processed and segmented before the display of the tumor portion. The tumor portion will be having a denser background as compared to the general image; this has been set up in our algorithm. Some image enhancement and noise reductions are done to enhance the image quality, after that some morphological operations are applied to detect the tumor in the image.

Interleaved Boost Converter (IBC) topologies have received increasing attention in recent years for high power applications. It serves as a suitable interface for fuel cells to convert low voltage high current input into a high voltage low current output. The advantages of interleaved boost converter compared to the classical boost converter are low input current ripple, high efficiency, faster transient response, reduced electromagnetic emission and improved reliability. This paper focuses on power loss analysis of the interleaved converter with winding –cross-coupled inductors and switched-capacitors. The performance parameter of interleaved converter such as switching losses, conduction losses and efficiency has been studied. Simulations of IBC interfaced with fuel cells have been performed using MATLAB/SIMULINK.

Aim of this article, classification statistical and power characteristics of the command brain motor with different structures of powerful perceptron neural network Combined with Levenberg Marquardt algorithm and evaluating the best structure to separate these signals. Detection of motor steering signals in the brain is an important classification issue. The discrete wavelet transform to extract features and investigate of the scale-frequency electroencephalogram signals are used. Results show perceptron network with two hidden layers and twelve neurons with linear output transfer function at best 92% and then the multilayer perceptron with one hidden layer and transfer function tangent sigmoid 86% have ability to separate.

A primarily diagnostic tool for cardiovascular diseases ECG , a non invasive technique generally used during acquisition and transportation. Noises like channel noise, baseline wander noise, muscle artifacts, electrode motion, often embedded with ECG signal. In this paper a methology to overcome from channel noise embedded during the transportation of ECG signal, proposed in this methodology DFT of noisy ECG signal calculated using fast fourier transform (FFT) algorithm. The experimental result demonstrate the proposed method is superior to other with higher SNR and lower RMSE factor, performance comparison at 1.25 dB is demonstrated. Keyword: ECG, Channel noise, Gaussian function, FFT, Wavelet transform, S-Transform.

Collaborative Sensor Fault Detection (CSFD) technique is used to detect the faults in the sensor nodes of a fusion center in a robust distribution estimation scheme. This technique can identify the faulty nodes efficiently and improve the accuracy of the estimates. ASIC implementation is used to design the fusion center based on their applications. In this approach there occurs some limitations such as computational complexity; hardware implementation is quite complex and high power consumption. In order to overcome these difficulties, we modify CSFD and propose an ECSFD scheme. ECSFD is simple and requires lower computational complexity, thus lower hardware cost and power consumption can be achieved. Furthermore, ECSFD achieves almost the same performance as CSFD. VLSI architecture is developed for hardware implementation.

By and large in remedial field checking performed on the little part of a picture anyway it comes to fruition high cost and less transmission speed as a result of its gigantic picture measure. Continuously it is to a great degree troublesome errand to diminish the degree of the picture without loss of information. At this situation by using some pressure strategies which are having the ability of higher remaking quality we will diminish the span of the picture. In any case, the nature of a photo expect a key part in the solution. On account of this reason we proposed upgraded pressure procedures. As a piece of this method we are performing district based division procedure by part the picture into two locales, ROI and NONROI which are trailed by applying LOSS and LOSSLESS pressure strategies. By applying different wavelets for ROI and NONROI pictures, we will register the pressure proportion and recognize the best appropriate wavelet procedure. By then we will finish our requirements i.e. picture with high transmission speed, less cost and less size. At long last compacted picture should be transmitted through flexible and web organizations. This examination article guarantees bolster for the destitute society with in regards to savvy who are enduring with ailments.

In this paper, the structure of Hybrid Power Flow Controller (HPFC) is proposed in order to improve static voltage stability characteristics. HPFC forms a hybrid controller using IPFC series converters as a hybrid with existing parallel and passive compensator (SVC) in power system. Utilization of hybrid structures makes it possible to use converters for improving performance of both old and existing compensators in power networks. In this study, the power injection model (PIM) is used to model the hybrid power flow controller in Newton load flow. The aforementioned model is simulated in MATLAB software. The P-V curves of PQ buses of a typical system are evaluated by a continuous power flow (CPF) method to analyses the effect of this controller on static voltage stability characteristics. Meanwhile, SVC as existing devices in the system and UPFC and IPFC as state-of-the-art compensator devices are compared with the proposed hybrid structure. The amount of active and reactive power loss and improvement of loading limit of the system are used as main parameters in our comparison.
