The sheet metal forming of copper, aluminum alloys using conventional stamping processes posses various problems, because of the lower formability limits, spring back and the tendency to wrinkle compared to steel. The principle of electromagnetism using attractive force is adopted to modify the conventional stamping process, to form thin sheets of 0.05 mm thickness. Further, this process can be used to form many sheet metal components with less expensive tooling and lesser number of operations. This process ultimately leads to light weight, cost effective and better strength-to-weight ratio components required for aerospace applications. In this study, a maximum of 30.77 % reduction in diameter was observed at 2.75A using electromagnetic forming which leads to the absence of spring back.

Currently, several microwave filter designs contend for use in wireless communications. Among various microstrip filter designs, the reconfigurable planar filter presents more advantages and better prospects for communication applications, being compact in size, light-weight and cost-effective. Tuneable microwave filters can reduce the number of switches between electronic components. This paper presents a review of recent reconfigurable microwave filter designs, specifically on current advances in tuneable filters that involve high-quality factor resonator filters to control frequency, bandwidth and selectivity. The most important materials required for this field are also highlighted and surveyed. In addition, the main references for several types of tuneable microstrip filters are reported, especially related to new design technologies. Topics surveyed include microwave and millimetre wave designs for 4G and 5G applications, which use varactors and MEMSs technologies.

There is always a great challenge for physically challenged and aged peoples of middle class people to move in bus stops, bus stands, hotels, working places, etc., for benefit of such peoples the cost effective E-Vehicle is designed to move from one place to another in certain level of distance. The EVehicle is a three wheeler, one wheel at front and two wheels at rear. The E-Vehicle has a comfortable seat for the person to sit and it also has a cabin to accommodate batteries and the controller setup. This E-Vehicle is nil emissive and produces very less noise. This E-Vehicle is made to have more energy efficient than the IC Engines. The Vehicle is of light weight to increase its operating efficiency. The main aim of this work is to have a comfortable travel in indoor and outdoor places.

Light-weight network gateways often employ a cost-effective embedded network processor and have received a strong demand for empowering content filtering services. In this regard, we were motivated to propose a specialized cache, fuzzy-updated cache automata matching (FCAM) circuit for accelerating the embedded network processors. Although automata matching algorithms are robust with deterministic matching time, there is still plenty of room for improving its average-case performance. The proposed FCAM employs cache to accelerate the root state and nonroot state with the multiple characters matching, and applies the fuzzy decision to improve the cache performance. In our experiment, the FPGA implementation of FCAM can perform at the rate of 10.5 Giga bits per second with the patterns of 25,642 bytes. This performance is superior to previous matching hardware in terms of throughput and pattern set.
