Abstract

Memory is one of the key elements in any of the electronic systems. But, Multiple Cell Upsets (MCU's) are becoming serious reliability problems to the memories when they are operated in radiation environment. So to protect memories, complex Error Correcting Codes (ECC) are proposed to overcome data corruption but the issue with them is that they need higher delay overheads., Decimal Matrix Code (DMC) has been proposed for the protection of memories which uses a decimal algorithm to enhance memory reliability. In DMC, the area of the circuit is minimized by using Encoder Reuse Technique (ERT) (i.e. encoder is reused in the decoder). But it requires a higher number of redundancy bits. So, to reduce redundancy bits and to improve error correcting capability, another technique called Parity Matrix Code (PMC) is used with the same algorithm as that of DMC with reduced redundancy bits and performance overheads. The drawback of existing DMC algorithm is that it requires more number of redundancy bits. This drawback was rectified in the modified PMC technique thus reducing the number of redundancy bits used for detecting and correcting the data. Thus modified PMC technique is more advantageous than an existing DMC technique because it has less number of redundancy bits with maximum error correction capability and Efficient Power, Performance and Area (PPA).

Abstract

Nowadays, Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) has found its usage in each and every field. Researchers are always trying to redesign the circuit by using Complementary Metal-oxide Semiconductor (CMOS) technology which gives the efficient circuit of MOSFET. To design sensor for aerospace application, that it uses sigma delta Analog to Digital Converter (ADC). To design difference amplifier, high gain operational amplifier plays a key role. The proposed work modifies the differential amplifier design using R-2R technique and also uses reduced operational amplifier. Thus it outcomes the consumption of energy and frequency reduced due to optimized op-amp design.

Abstract

Hand gesture recognition is critical to human-computer interaction. This paper proposes a revolutionary permanent method for hand gestures and presents a framework for detecting rapid gestures using information combination techniques and a direct indicator of hand development. The foundation subtraction approach in this system removes the arm area from the foundation. This structure is currently adopted by the procedures for implementing the Kinect V2 application. The required time is confirmed quickly compared to other ongoing minutes. The time analysis is compared and using the data pooling approach, the average time is 63ms. The average time is 45 milliseconds when using Rapid Data Integration. The time it takes to recognize hand movement has been reduced. MATLAB is used to analyze the results of experiments.

Abstract

Electricity is widely consumed in the everyday life of an individual, especially when used for light bulbs. Excessive consumption of electricity greatly affects the ecosystem. Nonetheless, Arduino Uno is used by the researchers as a microcontroller to control a light bulb with the use of a Passive Infrared (PIR) motion sensor in order to enable a user to program their specified schedule for when it will only turn on. The researchers use a Descriptive - Evaluative Design in order to measure the accuracy and efficiency of this device. The device acquired good results and functioned as of how the researchers programmed it to be. Based on the study conducted, the Arduino Uno device made by the researchers consumed fewer kilowatts per hour, calculated in a span of five days.

Abstract

The ability to control the electron flow of a Metal-Oxide-Semiconductor Field-Effect Transistor MOSFET decreases due to a quantum mechanical effect as the size decreases below 50 nm. To meet this challenge, a new area of device research is needed. One such area is devices based on tunneling phenomena, called single-electron devices. In this paper, the most fundamental single-electron device, the Single Electron Transistor (SET), is designed using visual Technical Computer Aided Design (TCAD) with a gate length of 2 nm and a gate width of 2 nm. The channel is ultra-thin with a length of 2 nm and a width of 0.005 nm, and the thickness of the channel is 0.3 nm. Then, a Si quantum dot with a size of 0.5 * 1.6 nm2 is used between the island and the gate. Both devices are successfully simulated using Genius Simulator. It has been established that a device with a silicon dot is more promising at room temperature. A device with a silicon dot has a lower capacity and higher charging energy than a device without a quantum dot.
