An Automated Garage Door and Security Management System (A dual control system with VPN IoT & Biometric Database)

Abstract: Internet of Things (IoT) have revolutionized the entire way in which the industry operates. The authenticity and entry access to certain places of the industry plays a crucial role in maintaining the secrecy of the operations. Therefore providing limited access to such confidential places proves to be seemingly vital. The proposed work provides a dual security mechanism against unauthorized entry and hence enhances the integrity of the system. This system thus eradicates the common security threats such as Spoofing, Repudiation and trafficking from evaders especially in the current scenario of industry 4.0. This system uses two techniques for the controlled access. One via a fingerprint access that utilizes the raspberry pi3 and a biometric database system for control. This method is a thorough hardware based solution and could be utilized when there is a physical presence of a person. In case if the authenticator is not available in the arena, the alternate mechanism would be followed to provide a secured access authenticity through Virtual Point Network (VPN) & IoT. The utility of VPN facilitates the personnel to prove his / her credentials from any remote location. Thus this dual mode system provides a highly credential entry / exit system in an industrial arena.

Accuracy Reconfigurable Adder for Low Power Of Sobel Edge Detection Algorithm

Abstract: A edge or contour on the edge of an image undergoes a significant shift in intensity levels. For these strong shifts in the images, edge detection is the technique adopted. The purpose of developing low power sobel edge detection in FPGA. The simple edge detection circuit was initially modified to cut the overall power consumption performed in software simulation with low power adders. The pixel values of the image are passed on to the Xilinx architecture. A limited selection of pixels is collected in order to acquire edges and non-edges, and absolute values relative to the predefined threshold value are calculated. If the gradient exceeds the threshold value it is known as a rim, otherwise it is discarded. The high computational complexity of multimedia applications is provided by rapid and energy processing power cores on mobile devices. The reliability of the arithmetic unit affects the machine’s overall output in these cores considerably. This paper therefore introduces a CLA-based carried look ahead and a new approach to approximate sum generation for the powerful precision reconfigurable adder (AR) architecture, namely ARCLA. The proposed architectures of AR-CLA can be reconfigured to provide high energy performance at the cost of a reasonable loss of consistency. In contrast to the current adder design figures the performance measures of the proposed adder designs as a standalone device show a significant improvement.

IoT-Based Water Quality and Quantity Monitoring System for Domestic Usage

Abstract: This chapter proposes an IoT-based system that monitors the level of water tank, flow rate of water, and water quality factors like pH, turbidity, and temperature. Quality of water is mainly affected by various pollutants and discharges from industries. The local water distribution is also to be monitored to avoid the problems that arise during water distribution like leakage of water and breakage of pipelines that lead to the wastage of water. This proposed online water monitoring system involves monitoring of physical and chemical properties of water and level of the distribution tank. In the process of monitoring, the data from sensors are collected and given to Arduino. The data obtained from sensors are compared with the standard values, and the necessary remedial actions are taken with the available data. Existing monitoring system involves complex testing methods and also consumes more time. So, this proposed system with Internet of Things jointly with the sensors for governing the quality and quantity of water improves the quality of water supplied and also avoids its wastage.

Analysis and Modeling of various Tapered Coplanar Waveguide

Abstract: This paper proposes the analysis of investigations on various tapered Coplanar Waveguide (CPW) structures to achieve increase in phase shift per unit length and the reduction in line length. The analysis of the tapered CPW is important in order to obtain the characteristic impedance and phase velocity of the transmission line. The step tapered CPW structures proposed have the center conductor, the gap/ground or both the widths varying having constant characteristic impedances for a fixed line length. The conformal mapping method is applied to the proposed tapered CPW structures to obtain the electrical parameters of the transmission line. The obtained impedance can be utilized in the design of RF circuits such as phase shifter using MEMS bridges.
