With new technologies surfacing day-by-day, we can use them to make new products and even can modify the existing ones. In a practical implementation, it is possible to use electric motors to open and close a refrigerator door. This can be done by reversing the direction of motion of motor when required. Reversing the polarity of the starter winding will solve the purpose. There are many ways to operate a motor and control of motor from human voice is one of them. In this application, a microcontroller-based voice input electronic circuit is designed, which can be used to rotate the motor in the required direction and hence to open and close the refrigerator door. The motor is connected to the axis of the refrigerator door. The relays are connected to the electric circuits for straight and reversed polarity. The motor operates in a direction as commanded. Microswitch are used to send signal to the microcontroller, which further stops the power supply to the relay and ultimately stops the motor rotation.

The demand for electricity has been rising at an exponential rate since Independence. Though the power generation has increased manifold over these years, but it has not been able to keep pace with the increasing demand. Keeping in mind the per capita income in the nation, the policymakers need to arrive at a sustainable energy model to integrate self-sufficiency with affordability. The Coal Linkage agreements between the power stations, the Indian Railways and the coal blocks which were established a long time back continue to exist till today. Even though the rail connectivity and the number of mines have improved over these years, no major changes have been made in the coal allocation model pan India. The study seeks to optimize coal transportation cost for 19 NTPC owned power plants using Linear Optimization techniques and seeks to evaluate the annual profitability of these power stations. The study does not suggest the adoption of this optimized model but aims to draw an insight of the dire need to reallocate the coal blocks to achieve higher levels of supply chain surplus which could be passed on to the customers as customer surplus.

The basic requirement of any Integrated Circuit is high speed and low power processing of the data signals to perform the desired execution. The minimization of feature size plays an important role in increasing the performance of integrated circuits. However, the minimization of ICs has affect on leakage current when compared to the total current requirement of the circuit. So in this work presents the design of single bit magnitude comparator & 3 input EXOR gate using conventional CMOS logic style as well as DCVSL style. Then, the comparison has been carried out for both the designs with some parameters. These parameters are power dissipation, delay and how much transistors have been used in the respective designs, and then concluded that which design yields best results accordingly. In CMOS circuits, as the technology scales down to nano scale, the sub-threshold leakage current increases with the decrease in the threshold voltage. So we need a technique to tackle the power dissipation problem in CMOS circuits do the analysis keeping parameters such as power consumption, delay, voltage & transistor count. First, there is the analysis between power consumption & delay, keeping the voltage constant at 5V. We here can see that circuit of the DCSVL structures produces better results in terms of power consumption by lowering its value. The circuit designed using DCVS Logic style is an attempt to further reduce the power dissipation with minimum delay.

As the population of cities around the world is increasing at a rapid pace, cities have started addressing this problem by the implementation of significant sensing and actuation infrastructure and building services on this infrastructure. Potential for conflicts across Smart City services increases with the increasing density of sensing and actuation and growing complexities of services. These conflicts can cause unsafe situations and disrupt the benefits that the services that were originally intended to provide. The proposed system detects and analyses the runtime conflict in smart city transportation services using real-time data feed. We will prepare an architecture, which will focus on conflict that arises on these services. 1. Train 2.Tube 3.Bus our architecture solution identifies the conflict and provides broad perspective to decision making aspect of services.

Let G = (V,E) be a (p, q)-graph. A graph G is said to admit a triangular sum labeling, if its vertices can be labeled by non-negative integers so that the values on the edges, obtained as the sum of the labels of their end vertices, are the first q triangular numbers. In this paper, we obtain a necessary condition for an eulerian graph to admit a triangular sum labeling and show that some classes of graphs admit a triangular sum labeling. Also we show that some classes of graphs can be embedded as an induced subgraph of a triangular sum graph.

Conventional wastewater treatment methods can be replaced by adopting MFC. The organized project conducted satisfactorily represents MFC as a convincing technology to treat dairy effluent along with generation of energy. The primary object of the existing paper “Treatment of Dairy Wastewater using MFC Employing Zinc Electrode” is to examine the efficiency of dual chambered MFC having continuous feed of substrate. The substrate employed is dairy effluent. The developed design parameters are established by checking out the responsibility of employing silver nanoparticles integrated salt bridges, Zinc electrodes and altering detention time. Zinc electrode having surface area of 123.4 sqcms is finding to be most stable performer. The detention time of six hours is found to be optimum for maximum output. For optimized experimental set up the maximum efficiencies obtained in removal of COD, BOD, EC, TDS and Oil and Grease were 77.58%, 75.02%, 65.95%, 57.96% and 67.32%. Maximum power and electrical energy generated were 21.483 μW and 0.0386694 Watt-sec respectively. From the results obtained the conclusion was MFC is efficient in replacing conventional method of treating dairy wastewater. It can treat efficiently along with energy generation.

The Bellandur Lake is the largest manmade lakes in Southeast Asia. Varities of pollutants have been reported to cause deterioration of water quality in Bellandur Lake. A study was carried out for An Approach to the Cause for the Foam Formation in Bellandur Lake Southwest Region, Bangalore. The water samples collected and measured at twelve locations during January-2018 to April-2018. The physic chemical parameters like pH, EC, Total Dissolved Solids, Turbidity, Sulphate, Oil and Grease, Phenols, Hexa-valent Chromium, Boron, BOD, COD, Phosphates and Nitrates, heavy metals like Fe, Cu, Zn, Ni, Pb, and microbial tests carried out during the study. The observed values of various parameters are compared with standards values recommended by BIS. The fall in water quality of Bellandur Lake is due to sewage and effluent discharge, washing cloths and utensils, religious ritual activities. Even though some parameters are within the range, parameters which help in foam production are found to be present. They have lower rate of settling. Hence, they react with chemicals present in lake water leading to formation of ignitable gases like H2S, nitrates etc. As they move on the surface of water, they mix with air and due to turbulence, foam is formed. Only 1 % of foam is formed due to foaming agent other than 99% of foam is due to air and water. Enrichment of foam due to organic and in organic components, heavy metals and chlorinated hydrocarbons. Foam catches fire due to high flammability compounds that are hydrocarbons and an organic polymer from industry. Continuous monitoring required in order protecting the lake from pollution.

Control valves are generally used as flow control equipment in many industries. The parameter for the performance of control valve analysis is flow coefficient. There is an experimental method to calculate the flow coefficient value of the valve, but the setup for the experimental validation is not readily available as these valves work at high pressure. Due to the progress of the flow simulation and numerical technique (CFD), it becomes possible to observe the flows inside a valve and to estimate the performance of a valve. This paper reviews the researches of the authors in modeling and simulation of the different control valves. The results of this paper provides people with the access of understanding the flow pattern of the valve with different flow rate and also determines the methods which could be adopted to improve the performance of the valve.

Dynamic Voltage Restorer is a Power Conditioning equipment that can compensate voltage sag and swell of the source voltage with the integration of Ultracapacitor. The innovative Scheme of this paper is the integration of UCAP with DVR, therefore this configuration of DVR can independently compensate the load voltage without utilization of grid voltage to compensate voltage sag and swell as in the existing system. The UCAP charge or discharge during supplying real power to the DVR. So, it is required to maintain the voltage profile of UCAP, this is achieved by incorporating the Buck-Boost converter between the base of the Inverter and Input stage of UCAP. This DC/DC Bidirectional converter provides the constant dc link voltage for the Voltage Source Inverter(DVR) for satisfying operation. The main complex thing in this work is design and control of DC/DC Buck-Boost Converter and Voltage Source Inverter. The whole model is designed and simulated in MATLAB/Simulink. The control strategies of Bidirectional Converter involve PI controller and DVR is controlled by PWM technique. The performance of DVR is validated with the results.

Water management plays a vital role in steel industry. The present work is carried out in cold rolling mill aiming to recovery maximum water. In CRM process the acid waste, alkaline waste and oil and grease wastewater generated. This wastewater is treated in effluent treatment plant and then it is desalinized to avoid the salt concentration in water circulation system by implementing ultra-filtration and RO system. It is found there is membrane fouling in RO3 system due to increase in hardness at the inlet it is reduced by adding lime and soda ash. Results shows that most salts are removed by UF and RO treatment and high quality of water is obtained. It is found that reusing the desalinated wastewater found more economical then discharging.
