01 Smart Water Conservation and Management System Using IOT
(Water Utility Monitoring and Control Using IOT Based Approach)

Anirudh Das.B, K.S.Srivatsava, Pradeep Doss

Abstract
The water needs have increased unpredictably throughout the world during the past few decades. This increasing demand of water supply has become a major challenge. We present an IoT based design for water monitoring and control approach which supports internet based data collection on real time basis to overcome this challenge. The device comprises of: a computer system (Central Hub), the IOT Module, the switching unit and the Zigbee module. The Internet of Things is a robust network of devices, all embedded with electronics, software, and sensors that enable them to exchange and analyze data. Firstly, the centralized hub is used for distributing water individually based on the needs of each household. The centralized hub works with the help of IoT that assists in integration of communications, control, and information processing across the systems used. This allows us to sense the water quantity and quality at each structure in one particular sector and provide control of water supply through a remote access. According to the deficit or the excess water level in a rank, the centralized hub monitors and shares the water among the localized tanks or resupplies water from its reservoir. It is used to create personal area networks in this scenario where there is a need for wireless connection across the system. We also improve the quality of water distributed to every household by deploying UV treatment. Fluoride content level along with hardness checking is also done using respective test meters.

02 Design and Analysis of Quasi-Yagi Metamaterials Patch Antenna
Yashwant Mohan, Abhay Kumar

Abstract
This Paper Present the idea of recent developments and advancements in the field of wireless technology to realize high speed communication which is performed in wideband technology. In this paper the wideband Quasi-Yagi patch antenna is designed and fabricated using metamaterial unit cell. A patch antenna is notch-band, wide beam antenna which is fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a Roger-5880, at which a continuous metal layer bonded to the opposite side of substrate and it produce a ground plane. The proposed antenna resonates at 6.5 GHz with total field directivity 8.6 dBi, which improve result than other patch design. The design has been made on low cost material aluminium lossy. This paper also compares an output of a rectangular patch antenna with metamaterial antenna designed here. The simulation is done using CST Microwave Studio simulating software.

03 Stability Analysis of 2-D PSV System Represented by Givone–Roesser Model
Prashant K. Shah

Abstract
Multidimensional systems have been very interesting area from several past decades due to its increasing demands in various areas like digital signal processing, Image processing, Gas absorption, temperature measurements etc. As systems aremulti-dimensional in nature stability of those systems decreases due to more than one dimension. These systems are difficult to represent, such systems can be represented by discrete state space models. There are several state space models are available among them FM1, FM2, GR, and R are very famous models even though they developed before four-five decade. In this paper our focus is to derive stability conditions for two-dimensional (2-D) Periodically Shift Varying (PSV) filters using GR models. As PSV filters has applicable in various places like Image Scrambling, video scrambling, design multiplier less filters etc. To check whether PSV system is stable or not, we have derived twosufficient stability conditions for PSV filter which helps to tell about stability. After that using Matlab LMI tool box we have done various analysis also An algorithm using linear matrix inequality is proposed to determine the stability of a given 2-D PSV system. As well as examples and comparative analysis also discussed in terms of stability for GR model.
