 Abstract

The levels of heavy metals in the water can be deliberated as a serious matter of disquiet as it may be consumed and it signifies the degradation of water quality. The present study was carried out to investigate the seasonal variation of heavy metal contamination in fresh water bodies from Coimbatore region, during 2018-2019. Heavy metals in water samples were analyzed by Atomic Absorption Spectroscopy (AAS). There was an appreciable increase in metal concentration from the water samples collected from the selected study areas. The metal concentration in water samples during the present study was in the following order based on their abundance; Zn > Cu > Ni> Cd>Cr> Pb. In general, the sources of heavy metals in fresh water bodies could be attributed to the illegal activity of waste dumping and discharges from the nearby sewage treatment plant into that freshwater ecosystem which enhances the process of eutrophication, finally leads to degradation of water quality. This indicates the level of risk to human health. So there is a need for a constant monitoring of the heavy metals concentrations in the fresh water ecosystem.

 Abstract

In Our day-to-day life usage of vehicles are increasing rapidly. So the vehicle-related crimes, thefts, and violation of traffic rule increasing. So ANRP(Automatic Number Plate Recognition) is introduced which solves all the existing problems. As there are plenty of ANRP approaches as well as solutions, even there exist some unsolved problems like the characters on the number plate are unrecognizable, lighting also plays as a parameter and ANRP recognize only horizontal number plates but what about some angles number plates. In this paper, we approached some other techniques to overcome some existing problems, and the number recognized by the system will cross-compare with the database to retrieve the owner's information. This work presents the usage of CV and Keras to localize the plate and extraction of text from it.

 Abstract

The Fundamental Objective of this project is to save our earth from the waste of heat energy which is produce by the commercial vehicle. This heat energy mainly comes from there engine and exhaust. This heat energy pollutes the atmosphere due to which it increases the temperature of the atmosphere more than the actual temperature of the atmosphere. So, a small step toward to save the environment to decrease this kind of excessive energy loss and We are introducing a system by which we can recycle the waste heat energy and covert that energy in form of charge. This energy is totally made from the engine heat which is actual a power loss from a engine in the form of heat that will recycle the power loss in the form of Electric current and further we can store this electric current in the battery or we can use this electric current to charge the vehicle battery. As we all know today world is facing with a big crisis of power generation because the demand of power is high as compare to the generation of power that produces. So we are switching more towards to the renewable energy sources. In this project we use the Technic of Seebeck effect this effect create a voltage when there is temperature difference between the thermocouples device where if we put one side of device is heated and other is colder side this can generate the electric current.

 Abstract

A rain gauge is an artifact used in meteorological stations to help measure and collect precipitations that fall in a certain place. Precipitations are all hydrometeor tumbling to the earth from the climate, including precipitation, shower, hail, snow, and slush, mist, and so forth Downpour check networks give precipitation estimations a serious level of exactness at explicit areas at the same time, much of the time, the instruments are excessively inadequately conveyed to precisely catch the high spatial and worldly changeability of precipitation frameworks. Radar and satellite distant detecting of precipitation has become a suitable way to deal with address this issue adequately. Notwithstanding, among different wellsprings of vulnerabilities, the remote-sensing-based precipitation items are unavoidably influenced by testing blunders that should be assessed and described. While the rainfall is recorded by more than 3500 rain gauges set up by Indian Metrological Department and State Government. The precipitation value fluctuates from one spot to another and from one year to another. The annual average rainfall for the country is about 120cm and the country's Geographical area of km2 is equivalent to 3916 km3. The rainfall is measured by an instrument called a rain gauge. Rain gauge is also known as ombrometer or pluviometer. The rain gauge is classified as Recording and Non-Recording. The Standard non-recording rain gauge prescribed by the IMD is Symon's gauge. The details of the rain gauge can be obtained by Indian Standards IS 4986 2002. In our project, we have collected the data of rainfall from the year 2010-2020 in Mayiladuthurai District, Nagapattinam District, and Tanjore District. The details are to be studied then compared and analyzed in MS Excel and SPSS software. By using the collected rainfall data around 12 stations, we have prepared the chart. We have planned to set up the Standard Rain Gauge at AVC College of Engineering.

 Abstract

Wireless Body Area Networks (WBANs) are a small network of sensing element nodes that are deployed either within or outside the physical body. Due to the restricted transmission range and battery constraint in WBAN, the routing protocols can play a very important role in creating the communication between the nodes more practical and additionally prolonging the life of a WBAN. In a previous couple of years, development and analysis of the routing protocols in WBAN are very important and engaging research topic, particularly for applications in medical analysis.The energy scavenging studies have also become an important research area not only for the utilization of ambient energy sources but also for their high potential to replace the batteries especially for wireless body area networks (WBANs). Conventionally, batteries are used to provide energy to WBANs. The battery recharging or replacement is significantly impractical. Therefore, different energy scavenging interface circuits with different efficiencies have been proposed to overcome these limitations. This study focuses on energy harvesting and their potential utilization for low-power systems.
