High Speed Vedic Multiplier Design using FPGA
Vedic mathematics is an ancient system of mathematics, which was formulated by Sri Jagadguru Swami Bharati Krishna Tirthaji (1884 - 1960). After a research of eight years, he developed sixteen mathematical formulae from Atharvana Veda. The sutras (aphorisms) covered each and every topic of Mathematics such as Arithmetic, Algebra, Geometry and Trigonometry, Differential, Integral, etc.The word “Vedic” is derived from the word “Veda” which means the power house of all knowledge and divine. The proposed Vedic multiplier is based on the “Urdhava Triyagbhayam” sutra (algorithm). These Sutras have been traditionally used for the multiplication of two numbers in the decimal number system. It literally means “Vertically and crosswise”. Shift operation is not necessary because the partial product calculation will perform it in a single step, which in turn saves time. 16×16 Vedic multiplier is designed by using Urdhava Tiryakbhyam sutra and using rca adder .The 16 bit Vedic multiplier and array multiplier are designed by using Xilinx Spartan-3E FPGA.

Performance Evolution and Comparison Analysis of OFDM System for Channel Estimation
A Multiple inputs multiple output (MIMO) structures in wireless communication exchange are referred as a wireless communication system where a couple of antennae is used in both aspects of the communication exchange route i.e. Transmitter side and Receiver aspect. The communication exchange structures, which use more than one transmit and multiple obtain antennas are commonly referred to as a couple of input more than one output (MIMO) structures. The coverage place and the transmission ability of a wireless communication exchange system can be progressed by way of the usage of this Wi-Fi networking generation. In digital signal processing, the processing algorithms for interference suppression are becoming complicated with a couple of antenna at each end of the transmission channel. Additionally, the growing demand for those networks has become the frequency spectrum into a treasured aid. For that reason, there is a sturdy need for a method which could pack more and more bits/Hz. Any such device is known as multiple inputs multiple output (MIMO) gadget. The uplink insurance and capacity of OFDM structures with the traditional multi-user detector receiver are interference restricted. In particular, at some stage in the rollout segment, the coverage of OFDM machine is uplink restricted. A less expensive answer to improving the general overall performance is using serial interference cancellation (SIC) at the base station. In this research work, a sophisticated receiver structure for interference cancellation primarily based on advanced Least Square Error Algorithm set of rules for multiple inputs multiple outputs orthogonal frequency division multiplexing (MIMO-OFDM) structures is proposed. The proposed method no longer simplest increases the capability of the device but additionally low down the Bit Error Rate. It could make full use of the channel correlations in the area, time, and frequency to estimate the channel state information for diverse systems, together with pilot-image assisted structures, pilot-embedded structures, and blind structures. MATLAB R2013a has been used to evaluate the performance of proposed algorithm the usage of Wireless Communication toolbox and preferred MATLAB toolbox. The overall performance of the proposed technique and existing technique is measured using BER.

The Terrestrial Alien Invasives of Family Asteraceae in Punjab (India) and their Ecology
Punjab, a northwestern state of India, is one of the main agricultural states of the country which produces wheat, rice, and sugarcane in massive scale every year. The state is rich in terms of biological diversity. However, the invasion of alien species is posing a risk not only to the community composition but also to the agricultural economy of the state. Among several terrestrial invasives of India, mainly two species of family Asteraceae, Ageratum conizoides, and Parthenium hysterophorus that are native to South America, are considered as the most obnoxious weeds to agriculture, ecology, and economy of the state of Punjab. These alien invasives are known for their persistence, adaptability, competitive exclusion and reproductive capabilities. All of these unique characteristics have made these species establish successfully in this new ecological region outside their native ranges.

A Review on Process Parameters on Tensile Strength and Hardness Testing of Friction Stir Welding Joint of Aluminium Alloys with Different Tool Pin Profile
Friction-stir welding (FSW) is a solid-state joining process that uses a third body tool to join two faying surfaces. Frictional heat between the welding tool and the work pieces causes the latter to soften without reaching the melting point, allowing the tool to traverse along the weld line. In this work, CNC Milling Machine is used to weld the parts together. The parts being welded are aluminium alloy AA5086 H32-AA6061 T6. The detailed mathematical model is simulated by Minitab17. In this investigation, an effective approach based on Taguchi method, has been developed to determine the optimum conditions leading to higher tensile strength. Experiments were conducted by varying rotational speed, transverse speed, and constant welding depth using L9 orthogonal array of Taguchi method. Effect of different tool pin profiles on the quality of the welded joint is also studied for welding. Different tool pin profiles considered are threaded, taper, circular/round and square. The tools are designed using Pro/E and are manufactured on a Lathe machine. After the parts are welded, various practical tests are performed on the welded parts that include the tensile strength and the Vickers’s hardness test.

Solar AC Power Generator with Arduino Control Circuit
We all know that sun provides a never-ending source of energy. This energy is called as Solar energy and it comes under the category of Renewable energy resources. Renewable energy resources are clean and non- polluting energy resources. Non-Renewable energy resources like the fossil fuels, oil, natural gas, coal and nuclear energy are not that much sustainable because they all take longer time for formation. Hence we expect more renewable energy resources and the device associated with these resources. The demand for solar cells or PV cells is increasing day by day. Solar cells convert solar energy into electrical energy. We can use this electrical energy according to our purpose of interest. The electrical power we obtained can be either in the DC or AC form. The output of Solar cells is strictly DC. From previous researchers, it is seen that we can directly produce AC power from solar cells without any use of inverter by simply arranging the solar cells in a circular pattern over a spinning disc and alternately exposing them. Although it eliminates the cost of the inverter, the major problem arises in controlling the speed of this spinning disk.The type of material for making the circular arrangement also plays an important role in better efficiency. The voltage and power obtained from the previous researchers are also less. In this paper, we modify the arrangement with proper speed controlling circuit by using Arduino in our circuit. The voltage and power obtained from this arrangement are more and hence efficiency is increased. The sine wave obtained is also of less distortion.
