In this study, stress analysis of a backhoe chassis was performed by using FEA. Construction industry is undoubtedly the backbone and propelling force behind our progress. In response to booming construction industry, utilization of earth moving equipment has increased considerably leading to high rate of failure. Backhoe Loader chassis is the skeleton of a commercial vehicles. The main function of the chassis is to support the different components like engine, cabin, transmission, front axle and rear axle. So it is necessary to analyze chassis to avoid failure while it is in working condition. Computer simulation techniques provides a great leverage in design optimization for weight reduction, better material utilization, shorter design cycles and elimination of major part of prototype testing.Static analysis of the chassis shows the equivalent stress and deformation contour when Backhoe Loader is in working condition. Aim of literature review is to find out high stress area at different load condition by stress minimized and weight reduction by giving design changes.

Pages: 9 - 13
The main aim of this Project work is to study experimentally the influence of depth of cut, cutting speed, and feed rate on the tool tip temperature, Material Removal Rate, Surface Roughness during turning process. The experiments will be obtained by varying one parameter while, the remaining two parameter were kept constant. So the influence of tool tip on different machining parameters is done in this research work. To increase the tool life, Taguchi Optimization method is used to optimization of machining parameters. The Taguchi method, a powerful tool of design optimization for quality, is used to find the optimal cutting parameters for turning operations. Through this study, not only the optimal cutting parameters for turning operations are obtained, but also the main cutting parameters that affect the cutting performance in turning operations will be evaluated. Experimental results will be provided to confirm the effectiveness of this approach. It will give the best result for turning operation of EN19 Material.

Mechanical Engineering (MACHINE DESIGN)
Year: 2014, Volume:1, Issue : 8
Pages: 14 - 16
The less efficiency of gear box of a machine tool is a serious problem as it increases maintenance cost and also affects the reputation of a firm. Hence its life has to be increased and should be made more reliable. The work to be done here is to find and rectify the causes of failure thereby improving the life of it. Also bearing failure should be reduced which is a cause of system failure. The alternative for the above problem is to design and optimization of a worm and worm gear box which reduced maintenance and improved reliability, lack of lubrication requirements, precise peak torque transmission, inherent overload protection, physically isolated input and output shafts, misalignment tolerance, and low acoustic noise and vibration etc. The parameters considered in the research are Lead Angle, Backlash and Bearing failure.

Pages: 17 - 20
In this review paper the results of an experimental investigation about the effect on Inconel 625 during hard turning using cubic boron nitride (CBN) based ceramic cutting tool. Turning experiments were carried out at different cutting speeds, feed rates and depth of cut. Tool performance was evaluated with respect to temperature, cutting forces generated during turning. The effect of cutting speed, depth of cut and feed rate on cutting forces & temperature during hard turning of Inconel 625 was experimented and analyzed by using taguchi method. Than optimize the cutting force & temperature using analysis of variance (ANOVA) technique.

Pages: 21 - 29
Image denoising is one of the most significant tasks in image processing, analysis and image processing applications. Medical Imaging is one among the emerging application areas where the image denoising plays a vital role. In medical imaging, the additional techniques and systems introduce noises and artifacts in the medical image that leads to poor quality image. In this moment, image denoising is an essential pre-requisite, specially in Computed Tomography, which is an important and most common method in medical imaging. The significance of the denoising is mainly due to that the effectiveness of clinical diagnosis using CT image depends upon the quality of the image. In this work, we propose an efficient noise reduction technique for CT images using wavelet transformation and thresholding. The technique removes Additive noise from the CT images as well as it enhances the quality of the images.

High speed Low Power Viterbi Decoder for TCM Decoders using Xilinx

Pages: 30 - 38
It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders. High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. We propose a pre-computation architecture incorporated with -algorithm for VD, which can effectively reduce the power consumption without degrading the decoding speed much. A general solution to derive the optimal pre-computation steps is also given in the paper. Implementation result of a VD for a rate-3/4 convolutional code used in a TCM system shows that compared with the full trellis VD, the precomputation architecture reduces the power consumption by as much as 70% without performance loss, while the degradation in clock speed is negligible.

Pages: 39 - 43
The vast usage of mobile applications have emerged a need for high speed data transmission and efficient and error free data transmission. For the purpose the use of multiple antenna systems at both the transmitting and receiving end is formulated known as MIMO Systems. It provides improved Spectral Efficiency and link reliability as compared to conventional systems. When it is combined with OFDM systems; it eliminates the fading effect and with requirement of lower Bandwidth it provides high Throughput. Yet having a number of advantages; it suffers from some limitations like ISI, ICI and PAPR. These are the factors which degrades the System Performance.

COMMUNICATION ENGINEERING
Year: 2014, Volume:1, Issue : 8
Pages: 44 - 48
The objective of this study is up channel estimation accuracy in OFDM system as a result of channel state info is needed for detection at receiver and its accuracy affects the performance of system and it's essential to improve the channel estimation for a lot of reliable communications. OFDM system was chosen during this study because it's been wide used nowadays owing to its high knowledge rate, data rate and its adequate performance in frequency selective attenuation channels. The pilots were inserted among subcarriers in transmitter with distances emerged of sampling theory then Least sq. (LS) technique & minimum mean-square error (MMSE) was chosen for initial channel estimation in pilots at receiver, mistreatment applicable projected receiver, that has straight forward and usable structure, then channel state info was calculable by linear interpolator in information subcarriers, that uses 2 adjacent channel estimation in pilots to calculate channel in another subcarriers and associate degree LMS repetitive algorithmic rule, as well as a feedback of output is another to system. This algorithmic rule uses the channel estimation of last iteration in current estimation. Adding a LMS repetitive algorithmic rule to system, improves the channel estimation performance. Simulation results established the acceptable BER performance of repetitive channel estimation algorithm, that is closed to the best channel. The low complexity projected receiver as well as LMS algorithmic rule, has a higher potency than typical methods (without channel estimation & LMMSE ) and it will add lower quantity of SNRs.
