Abstract

The reduction of the channel length due to scaling increases the leakage current resulting in a major contribution to the static power dissipation. For stability of the SRAM cell good noise margin is required so noise margin is the most important parameter for memory design. The higher noise margin of the cell confirms the high-speed of SRAM cell. In this work, a novel SRAM cell with eight transistors is being proposed to reduce the static power dissipation. When compared to the conventional 6T SRAM the proposed SRAM shows a significant reduction in static power dissipation while produce higher stability. The technique employed for the proposed RAM cell, the operating voltage is reduced in idle mode. This technique leads a reduction of 97.81% on static power dissipation. Cadence Virtuoso tools are used for simulation with 45-nm CMOS process technology.

Abstract

The region behind the car which are invisible to the naked eyes and to the side mirrors are known as Blind Spot. The vehicles present in the blind zone causes greater hindrance to the drivers and may result in accident. The existing blind spot techniques use RADAR technology which is much costlier. In this paper we proposed a technique which uses Ultrasonic waves to detect the vehicles present in the blind zone. This technique is much cheaper and it can produce greater accuracy than the existing methods. The detected vehicles are also displayed near the rear view mirror with the help of a camera and a LCD display device.

Keywords

Blind Spot, Ultrasonic, Radar, LCD Detection.

Abstract

Fluid handling equipment such as propellers, impellers, pumps posses the inherent risk of flow-dependent erosion-corrosion problems. Though there are many coating materials available to combat erosion-corrosion damage in the above components, iron based amorphous coatings exhibits high erosion-corrosion resistance. High velocity oxy-fuel (HVOF) spray process is extensively used to deposit erosion-corrosion resistance amorphous coatings. In this investigation, iron based amorphous metallic coating was deposited on 316 stainless steel using HVOF spray process by varying the parameters such as oxygen flow rate, fuel flow rate, powder feed rate, carrier gas flow rate, and spray distance. Empirical relationships were established to predict the porosity and micro hardness of iron based amorphous coating. Microstructure observations of the coating were done by optical microscope. From the results, it is found that, fuel flow rate and spray distance appeared to be the most significant parameters affecting the mechanical properties of the iron based amorphous coating.

Keywords

Abstract

This project is developed for an automation purpose which is suitable for juice making industries. For this, we will be using image processing for detecting the colour. By using image sensor, we will be monitoring the fruits which are moving in a conveyor belt. The monitored information will be sent to image processing section. By using LABVIEW we will be processing the images and as the result we will get an extracted colour of the input product. If the fruits are yellowish green, then it will be processed to the next section and if the fruits are not in expected colour, then we will get an alert saying that the corresponding fruit is not suitable for the next process. By using RTC, we will be monitoring the shift timings and based on the shift timings, production output will be calculated.

Abstract

Nowadays, in the area of casting, the focus is on cost and resource efficient production of increasing complex shapes, miniature precision component along with the considering environmental issues, put an all stringent requirements on the advances in casting technology. Casting is the primary manufacturing process is being developed at each and every stages over centuries of years to satisfy the needs of the customer. This paper reviews most of the advanced casting techniques and their advantages, limitations and applications in the field of engineering. The paper is divided into four sections, the first section details about the casting process within expandable mold with expandable patterns such as investment casting, full mold process and replicast process. The second section describes about the semisolid process such as thixocasting, rheocasting and thixomolding. The third sections explains non-bonded sand molding process such as vacuum molding and magnetic molding and the fourth sections associates with the centrifugal casting process such as De Lavand process and Moore casting process.
