Abstract

This article compares the accuracy achieved by the various Resistance Temperature Detector (RTD) configurations using the MAX31865 device. This design offers an interface for PT100 RTD using MAX31865 RTD to digital converter. The RTD is connected to the anti-aliasing filter and the filter output is converted into a digital signal using the MAX31865 device. The final temperature readout is monitored on the computer for validation. The proposed temperature sensor interfacing can be utilized in multi-channel temperature measurement in the telemetry systems. RTD sensor configurations with 2, 3 and 4 wires are evaluated and accurate results are obtained in 4 wire configuration. Furthermore, in this sensor interfacing Serial Peripheral Interface (SPI) output requires only one micro-controller unit, which reduces the circuit complexity and power requirement to a great extent.

Abstract

Nowadays, the industrial automatization is the need of the hour for improving process in various industries. On survey, it is observed that, it may help to increase the quality, reduces cost and time to get the product in market. The physiochemical monitoring and controlling is the challenging task in the field of Industrial sectors. Considering such facts, it is proposed to develop Remote Terminal Unit (RTU) to monitor the physical parameter. The present research work is carried out to monitor the pH of water in water treatment plant. For this purpose, the RTU is wired with FRDM-KL25Z based ARM Cortex™ M0+ core microcontroller along with sensing and signal conditioning capabilities are used. Moreover, the sensed and processed signal is transmitted towards supervisory computer through RS232. On other hand, the pH of the water is recorded on the supervisory computer of Supervisory Control and Data Acquisition (SCADA) system. The RTU is calibrated to demonstrate the pH in standard unit. The developed system works successfully for monitoring the pH of water under experimental conditions.

Abstract

In recent trends, power optimization and improvement of speed are the key researches in the VLSI circuit design. This paper presents an advanced hybrid full adder. Most of the adder has a powerful impact on the overall performance of the system. The modern design is correlated with some actual designs to enhance performance parameters such as power utilization, delay, and PDP. In the proposed circuit, the power delay product is maximum of 96.8% with respect to Complementary Metal-Oxide Semiconductor (CMOS) at minor frequency. The power utilization is increased at a slow rate in contrast to other adders with increase in frequency. The simulations are drifting out on Cadence Virtuoso at 130 nm. By correlating with the previous Full Adder (FA) designs, the present operation was found to offer a powerful improvement in terms of speed and power.

Abstract

This paper is the combined overview of the progress made in the field of Multicore Fiber (MCF) as well as in Photonic Crystal Fiber (PCF). These days, it has been seen that the MCF is the best option to overcome the previous technology used for the optical communication system due to the fact that it has large transmission capacity. In MCF, Space Division Multiplexing (SDM) transmission is used to enhance its transmission capacity by varying the parameters like number of cores and modes within it, whereas in PCF, the air holes are arranged in various geometries and are replaced by different materials such that the obtained parameters like confinement loss and dispersion can be reduced. The main objective of this paper is to use and combine the advantages of both MCF and PCF. This overview is done to analyze the optical parameters of MCF by varying its structural parameters. The calculations for analyzing the same shall be done in COMSOL Multiphysics software and the graph shall be plotted in MATLAB.
