In this paper, a two stage optimization technique is presented for optimum design of planar slider-crank mechanism. The slider-crank mechanism needs to be dynamically balanced to reduce vibrations and noise in the engine and to improve the vehicle performance. For dynamic balancing, minimization of the shaking force and the shaking moment is achieved by finding optimum mass distribution of crank and connecting rod using the equimomental system of point-masses in the first stage of the optimization. In the second stage, their shapes are synthesized systematically by closed parametric curve, i.e., cubic B-spline curve corresponding to the optimum inertial parameters found in the first stage. The multi-objective optimization problem to minimize both the shaking force and the shaking moment is solved using recently developedevolutionary optimization algorithms–“Teaching-learning-basedoptimization algorithm (TLBO)”. The computational performance of TLBO is compared with another evolutionary optimization algorithm (genetic algorithm).

Magneto Rheological damper is a special type of damper that is filled with Magnetorheological fluids which can be controlled by magnetic field using an electromagnet. These types of smart fluids change their physical properties when subjected to magnetic field and turn into visco-elastic solids in few milliseconds. This property allows the MR damper to be used as a shock absorber by controlling its damping characteristics by changing the intensity of electromagnet. This paper focuses on the various applications of MR dampers in latest technologies.

Wireless Communication has expanded and achieved great heights. It has increased demand for rate of data transmission using low noise clock. Fractional-N frequency synthesizer is used most commonly in today’s wireless technologies. This paper presents simulation and modeling of fractional-N frequency synthesizer and compares architectures that optimize quantization noise. Fractional-N frequency synthesizer is derived from integral-N frequency synthesizer using division control architectures such as Error Feedback Modulator (EFM), Multi-Stage Noise Shaping (MASH) and modified versions of MASH. Results show that fractional-N frequency synthesizer is capable of producing frequencies between 200MHz-225MHz with a phase margin of 48. Spurious noise is observed at -200dBc.

Ultra-wideband applications have grabbed much attention in the field of antenna because of it’s extremely wideband for high data rate applications. Since UWB antennas may transmit baseband signal without a carrier, the RF front end can be simplified and become inexpensive. .

Looking at today’s infrastructure on an overall basis it is very obvious that the higher the amount of comfort the infrastructure tend to provide to its users, higher is the cost. Materials, planning, designing, architecture & engineering all have grown to incur a very high cost when it comes to provide the best of designs in terms of looks, aesthetics and sustainability. But then if we persuade analytically upon the issues of costing at a higher rate in terms of infrastructure, by using resources that are available to us through nature coupled with providing designs in a way that both these things could be achieved in the most economical ways possible along with ensuring a well-built structure therefore, not compromising on quality at all. The paper hereby, deals with the aspects of the same thereby showing a detailed analysis using software and comparing normal vs improved designs on basis of light entrance, heat reduction, aerodynamics and dust reduction.

Growing non linear optical crystal is a fascinating research field today. Organic crystals have very high Second Harmonic Generation efficiency. In this view Zinc Sulphate doped L-Threonine single crystals were grown by slow evaporation technique in this study. The grown crystals were characterized optically by recording UV-Visible spectral study. The refractive index of the grown crystals are experimentally determined by Abbe’s refractometer. The optical band gap energy was determined from Tauc plot. The extinction coefficient, complex optical dielectric values and optical conductivity were also determined. A Cole-Cole plot were drawn between the complex dielectric. The single oscillator energy Eo and Ed also been determined. The SHG efficiency was also determined.

The purpose of this article is to identify the energy challenges faced by airports especially with regards to the energy consumed by the terminal building and suggest suitable energy conservation techniques based on what has already been implemented in few airports around the world. We have identified the various facilities and systems which are responsible for a major share of the consumption of energy by airport terminals and we have suggested measures to effectively overcome these problems.
