This train is equipped with a controller and an IR Object sensor that enables the automatic stopping of the train from one station to another station. This paper presents the development process of a prototype for a driverless train implemented using a RASPBERRY PI controller. Simulation for the systems circuits is done with LabVIEW software. The hardware circuit is interfaced with actuators and sensors for automation purposes using LabVIEW. A hardware comprised of IR sensor, RASPBERRI PI areassembled in a prototype train. A LabVIEW CODE is used for programming the controller. A Smoke sensor is also interfaced to detect any smoke or gas present in the train. Manoj Kumar M | Hemavathi.R | H.

Mahendra K. Mishra (MKM) talks to professor Debi Prasanna Pattanayak (DPP)
Get PDFDebi Prasanna Pattanayak, Founder Director (retired) of the Central Institute of Indian Languages (CIIL), Mysore, helped to place India on the international map of language studies. He is a highly respected sociolinguist and social scientist and has consistently fought for the cause of mother- tongue education. In his 1985 article he said Like air and water, language is indispensable for human society. When natural water is so parcelled out that a section of the people is deprived of even drinking water, or natural air is so polluted..., then this is the sign of an unequal society. Similarly when a society is denied full expression through the language which is used naturally and its needs are instead sought to be met through a regulated or imposed language, then inequality sets in
Large-scale processes in the upper layers of the Indian Ocean inferred from temperature climatology
Get PDFDetermination of amplitudes and phases for the annual and semi-annual cycle of the temperature in the Indian Ocean north of 20S from Levitus temperature climatology (1982) gives maximum amplitudes of the seasonal cycle at 100 m with the dominance of semi-annual cycle in the equatorial region and annual cycle elsewhere in the domain. The Bay of Bengal shows characteristics of the westward-propagating Rossby waves of annual period, while the Arabian Sea shows the dominance of Ekman pumping in the central region and westward-propagating features in the eastern region. Qualitative evidences obtained from the distribution of depth of 20°C isotherm and computed Ekman pumping velocities are consistent with the above inferences. From the time-longitude plot of the depth of the 20°C isotherm, the phase speed of westward propagating features from the west coast of India along 10.5N and 15.5N are found to be 7.8 cm s−1 and 5.2 cm s−1 respectively. This is consistent with the corresponding values computed and verified with theory for the Bay of Bengal (Prasanna Kumar and Unnikrishnan, 1995)
A Comparative Study on Anaerobic Co Digestion of Agricultural and Horticultural Waste
No full textAgriculture, apart from crops and livestock, is a source of large amounts of troublesome by products like different kinds of manure. Nevertheless, they could be successfully processed through anaerobic digestion technology, which allows for simultaneous waste utilization and energy generation. Production of biogas from manure only is low efficient due to the low dry matter content about 8 . The additional substrates, such as plants with high dry mass content, are used to improve the process efficiency. In this work biogas production technologies from different agricultural as well as horticultural feedstock was used along with the pretreatment with efficient cellulose degrading bacteria, a comparative experimental analysis between different types of biomass residues used for biogas production as estimation of biological oxygen demand BOD , chemical oxygen demand COD , cellulose, pH, Nitrogen, Phosphorus and Potassium during the anaerobic fermentation process. The comparison is achieved using as parameter the biogas quality and quantity which are produced, using different available agricultural and horticultural waste material. All the measurements were made on a lab scale pilot installation. B. Prasanna Kumar | Dr. S. Triveni | Dr. A.

Studies On Application Of Control Systems For Urban Water Networks
No full textManagement and supply of water in an urban water distribution system is a complex process, which include various complexities like pressure variations across the network depending on topography, demand variations depending on customers’ requirement and unaccounted water etc. Applying automatic control methods to water distribution systems is a way to improve the management of water distribution. There have been some attempts in recent years to develop optimal control algorithms to assist in the operation of complex water distribution systems. The difficulties involved by these hydraulic systems such as non-linearity, and diurnal demand patterns make the choice of a suitable automatic control method a challenge. For this purpose, this study intends to investigate the applicability of different controllers which would be able to meet the targets as quickly as possible and without creating undue transients.
As a first step towards application of different controllers, PD and PID linear controllers have been designed for pump control and valve control in water distribution systems. Then a Dynamic Inversion based nonlinear controller has been designed by considering the non-linearities in the system. Here, different cases considering the effects of initial conditions used, linearization methods used, time step used for integration and selection of gains etc., have been studied before arriving at best controller. These controllers have been designed for both the flow control problems and level control problems. It is found that Dynamic Inversion-based nonlinear controller outperforms other controllers.
It is well known that the performance of controllers is much dependent on the tuning of the gains (parameters). Thus in this study various alternative techniques such as Ziegler--Nichols rules (ZNPID), Genetic algorithms (GAPID) and fuzzy algorithms (FZPID) have been studied and a comparative study has been made Although with all the three gain tuning methods, required states have reached their target values, but the responses vary much in reaching to final targets. The self-tuned FZPID controller outperforms other two controllers, especially with regard to overshoots and the time taken to tune the gains for each problem.
Further, an optimal DI controller is developed for the over determined case with more controls and less targets. Energy loss is considered as an objective function and normal DI controller equations are considered as constraints. Hence, an attempt is made to reduce the energy minimization in water distribution system by formulating an optimal control problem using optimal Dynamic Inversion concept.
Finally, leakage reduction model is developed based on excessive pressure minimization problem by locating valves optimally as well as by setting valves optimally. For this purpose, optimization problem is solved using Pattern search algorithms and hydraulic analysis is carried out using EPANET program
