The molecular geometry, vibrational frequencies of 3-(trifluromethyl) phenyl isothiocyanate in the ground state have been analyzed using density functional theory calculation (B3LYP) with 6-311++G (d,p) and 6-311++G (2d,2p) basis sets. The optimized geometrical parameters obtained by DFT calculations are in good agreement with experimental values. Comparison of the observed fundamental vibrational frequencies of the 3-(trifluromethyl) phenyl isothiocyanate and calculated result by DFT/B3LYP/6-311++G(d,p)/6-311++G (2d,2p) is superior for molecular vibrational problems. A detailed interpretation of the FTIR and FT-Raman spectra of 3-(trifluromethyl) phenyl isothiocyanate are reported on the basis of the calculated potential energy distribution (PED).

We have dealt with the Backend design of LMS algorithm in Cadence tools. The LMS algorithm is used for the purposes of Polyharmonic Power Calibrator, Active phase cancellation of Hostile radars, and Noise cancellation. We have implemented the algorithm into VLSI technology using Verilog HDL, designed, simulated, and synthesized it using Xilinx Spartan3 3s400pq208 and the backend design is done using Cadence tools. The backend design for the LMS adaptive filter is done using RTL-GDSII So C encounter system and the So C design of the LMS algorithm had a power consumption of 32mW, timing slack of about 14ps and the design frequency is about 4.2Mhz also it uses an area of about 9753microns with a core size of about Ratio (H/W) 0.9204437. It is found that the backend implementation to be more efficient than the other methods of implementation.

Angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease. Angina is a symptom of a condition called myocardial ischemia. It occurs when the heart muscle (myocardium) doesn't get as much blood (hence as much oxygen) as it needs. This usually happens because one or more of the heart's arteries (coronary blood vessels that supply blood to the heart muscle) is narrowed or blocked. Insufficient blood supply is called ischemia. Major risk factors for angina include cigarette smoking, diabetes, high cholesterol, high blood pressure, sedentary lifestyle and family history of premature heart disease. . This causes the distal part of the heart does not receive any more blood and individuals will develop chest pain. Initially when the coronary disease is mild the angina will occur during exercise, eating heavy meals, extreme heat or stress. As the coronary disease worsens, the angina will come on with minimal work and may even occur at rest. The first approach in the treatment of angina pectoris is to prevent the progression of heart disease. By addressing the known causes of heart disease, such as reducing high cholesterol levels, controlling high blood pressure, stopping smoking, losing weight, exercising and eating a “heart-healthy” diet, the symptoms can be reduced. Most people can live a productive life if they make the necessary lifestyle changes. By following medical advice, taking doctor-prescribed medication, maintaining a good, physical condition and eating well, angina can be controlled. There are also natural alternatives to conventional medicine such as herbal and homeopathic remedies useful in controlling angina without the harsh side effects associated with prescription drugs. Herbal and homeopathic remedies are safe and gentle to use, while at the same time addressing the underlying causes of the condition.

Being future technocrats we tossed this idea with an aim to provide service to the society. Providing an overture for the visually impaired, to make them feel self-reliant and thus raise their status in the society is the ultimate aim of our project. The proposed concept consists of a smart stick that generates voice output using the voice arrays and pre programmed microcontrollers. This tool encompasses five constructive features. The pre-eminent feature is the Obstacle Tracer which uses ultrasonic sensors to detect the obstacles on the person’s way and redirects them appropriately using voice commands. Area Detector uses the GPS module to figure out the location and gives the output as voice stream. Destination alerter generates a voice alert to the person on reaching a landmark (such as bus stop, bank, post office etc….) In addition to these our contrivance also has the Onboard Alerter module that informs the person when a bus enters the boarding area. This uses the transmitters in the bus and receivers in the contrivance. The Off Board Alerter specifies the subsequent bus stops as soon as the person boards on the bus. Thus our appliance will help the visually impaired person to be independent in his own path.

We present a number of significant engineering insights on what makes a good configuration for medium- to large size wireless mesh networks when the objective function is to maximize the minimum throughput among all flows. For this, we first develop efficient and exact computational tools using column generation with greedy pricing that allow us to compute exact solutions for networks significantly larger than what has been possible so far. We also develop very fast approximations that compute nearly optimal solutions for even larger cases. Finally, we adapt our tools to the case of proportional fairness and show that the engineering insights are very similar.
