Low power and area efficient shift registers using pulsed latches

The power consumption and area reduction are the key challenges in the Very Large Scale Integration (VLSI) circuit design. The shift register is the main building block in the VLSI circuits. The shift register is composed of clock interconnection network and timing elements such as flip-flops and latches This clock entomb association system and timing component is the primary power and region expending component in the move enlist. This clock interconnection network and timing element is the main power and area consuming element in the shift register. This project introduces a low power and area efficient shift register using pulsed latch and pulse generation circuit. The area and power consumption will be reduced to 50%in the shift register if the Flip-Flop is replaced with the pulsed latch. This technique explains the timing problem between pulsed latches through the use of multiple non-overlap delayed pulsed clock signals as an alternative of the conventional single pulsed clock signal.

Seismic analysis of five and eight storeys concrete and steel building frame at different zones of earthquake

Earthquake is the major impact on everyday life. It causes huge damages to structure especially building a structure. In this circumferential, we need accuracy in the design so the assessment of the design and execution will be correct. The main focus in this paper to check the adequacy of the material used in the building and conclude that either steel and concrete which one is more suitable for two different sized frames five storeys and eight storeys frame structure. The amount of deformations in the frame has been calculated and compared with the deformations of different zones. The three different zones are taken here for the comparison in deformation (Zone III, IV, and V). Five and eight storeys framed structure were subjected to seismic analysis of different magnitude. The seismic analysis was performed in ANSYS using time acceleration histogram for different zones. It was observed that structures performed well in areas which were less prone to earthquakes. Stability of five framed structure was more than that of eight storeys framed structure.

Automatic irrigation system using PLC

India is an agriculture country and all its resources depend upon the water, and water is becoming one of the most precise natural resources. Irrigation may be defined as the process of artificially supplying water to soil for raising crops. A solar panel is used to charge the battery and by using inverter it is converted into AC. The field humidity is prime parameter considered for plantation of different plants. It is controlled by sensors, for minimum and maximum humidity. The field is irrigated by a separate valve. The valves are controlled by the PLC. Through feedback control mechanism, humidity of the fields is maintained at the certain level. In PLC based drip irrigation system we control the percentage of moisture in the soil. The developed irrigation system removes the need for workmanship for flooding irrigation. So we use PLC programming if there is immense need of water to the crop in order to get maximum profit with minimum cost.

Degradation of formaldehyde using ZnO powder as photocatalyst

In the present study, commercially available Metal Oxide powder was used for the degradation of Formaldehyde in an aqueous phase. The Photocatalysis oxidation was favored at neutral pH. The effect of catalyst concentration, operating temperature, and the stirring effect was studied. The reflector was used in order to increase the impact of UV light for Photocatalysis process. For 500 mg/L concentration of Formaldehyde in an aqueous phase, degradation was observed and the catalyst was recycled using physical separation method and reused. Similar results were observed in the recycled catalyst.

Design of high-speed multiplier by using carry select adder

An adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors in the arithmetic logic units, adders are used. In other parts of the processor, they are also utilized. Where they are used to calculate addresses, table indices, increment and decrement operators, and similar operations. Although adders can be constructed for many number representations, such as BINARY-DECODED DECIMAL or EXCESS-3, the most common adders operate on binary numbers. We designed an adder which is of high speed and applied this to a new multiplier for better performance multiplier by using CARRY SELECT ADDER in this project. In arithmetic operations, addition and multiplication are having a major role. When the number of bit increases, the complexity of the adder circuits increases and the speed performance decreases. The delay will be very much reduced proposed carry select adder based multiplier on comparing with carrying look ahead adder based multiplier, and the carry save adder based multiplier. The code is written in VHDL and Verilog and synthesized the design in Xilinx ISE 14.1.

Implementation of integer order PID controller and fractional order PID controller using genetic algorithm for maglev system

Maglev is the latest technology which has been implemented in most of the foreign countries. It is a method by which an object is suspended in air by means of magnetic force. As it does not have moving parts, the wear and tear of the parts are minimal. But the problem with the magnetic levitation system is its stability. So in order to stabilize the system, several controllers must be used. This paper chooses integer order PID (IOPID) and fractional order PID (FOPID) controllers to stabilize the system. As PID controllers alone cannot meet the required specifications, an optimization technique is used to found out the controller parameters. Due to its high potential for global optimization, genetic algorithm(GA) has been used to tune the controller parameters. On an overall, this paper presents a study on the comparison between IOPID and FOPID controllers with and without genetic algorithm(GA) in magnetic levitation system.
