The heightened utilization of ionizing radiation for diagnostic and beneficial purposes, the expeditious progress in nuclear reactors, as well as the risks of radioactive waste have raised significant safety and health concerns for the people working with radiation and the general public. While some exposure to radiation is acceptable, radiation monitoring should be done to keep the levels of radiation...
The development of remote automation of a cascade control system by using CC3200 microcontroller is presented here. The cascade control system has two variables , namely level and flow. The liquid level which is referred as primary variable and it is used to control the flow (secondary variable). The cascade process, i.e., level and flow is monitored and controlled by using CC3200, a System on Chip...
Control of climatic condition inside a closed area involves complex control strategies and schemes, in this work controlling of two highly interacting process variables temperature, relative humidity for establishing climatic conditions is discussed. An experimental setup of climatic chamber with heating, ventilating, air conditioning units is developed as a 4 × 2multi input multi output system to...
Securing Grid protection in Wireless Sensor Grids (wireless sensor networks) several attacks that have been recognized in wireless sensor network till now by the researchers and still it's increasingly becomes critical. Sybil attack is one of the harmful attacks against sensor Grid where a number of appropriate individualities and forged individualities are used to get an inappropriate entry into...
This paper introduces the Kannada Corpus tool, a suite of Perl (Program Extraction and Reporting Language) programs implementing an iterative procedure to build Kannada corpora from the web. The procedure requires is, first a set of "seed" words list is built and later a set of “seed” URLs (Uniform Resource Locator) containing documents in the Kannada language is collected by sending queries...
The paper presents the proportional, integral and derivative (PID) digital controller based cascade control system and its experimental validation through three different testing scenarios namely, control action through Supervisory Control and Data Acquisition (SCADA), control action using Programmable Logic Controller (PLC) and interfacing of PLC with NI-OPC server. In this study, Micrologix-1200...
The present study aims at bringing out the best features of model-based control, when applied to highly non-linear systems like pH-controlled fed-batch processes. For these processes, control of pH by conventional PID controller fails to provide satisfactory performance, because of the extreme non-linearity in the pH dynamics. In the present study, for a fed-batch neutralisation process, a non-linear...
Due to the extreme nonlinearity in the pH characteristics, control of pH in any chemical or biochemical process is a difficult task. Different approaches for pH control are proposed in various literatures. In the present study, control of pH neutralization process using neural and fuzzy controller is proposed. Initially a conventional linear controller is tried to control the pH at different linear...
