Authors- ANCHAL KATIYAR, PRAGATI SACHAN, ANITA DIDAL, PALLAVI GAUTAM

Abstract- Vending machines are used to dispense small different products, when a coin is inserted. These machines can be implemented in different ways by using microcontroller and FPGA board. Here in this paper, we proposed an efficient algorithm for implementation of vending machine on FPGA board. Because FPGA based vending machine give fast response and uses less power than the microcontroller based vending machine. The FPGA based vending machine supports four products and three coins. The vending machine accepts coins as inputs in any sequence and delivers products when required amount is deposited and gives back the change if entered amount is greater than the price of product. It also supports cancel feature means a user can withdraw the request any time and entered money will be returned back without any product. The proposed algorithm is implemented in Verilog HDL and simulated using Xilinx ISE simulator tool.

9. TRAFFIC LIGHT CONTROLLER

Authors- ANITA DIDAL, ANCHAL KATIYAR, PRAGATI SACHAN, PALLAVI GAUTAM

Abstract- Traffic congestion is a severe problem in many modern cities around the world. To solve the problem, we have proposed a framework for a dynamic and automatic traffic light control expert system combined with a VHDL code. This adopts inter arrival time and inters departure time to simulate the arrival and leaving number of cars on roads. Each sub model represents a road that has three intersections. The paper aims to design a Traffic Light Controller using VHDL and implement the Traffic Light Controller in FPGA. The traffic in road crossings/junctions are controlled by switching ON/OFF Red, Green & Amber lights in a particular sequence. The Traffic Light Controller is designed to generate a sequence of digital data called switching sequences that can be used to control the traffic lights of a junction in a fixed sequence. The simulation results physically prove the efficiency of the traffic system in an urban area, because the average waiting time of cars at every intersection is sharply dropped when the red light duration is 65 s and the green light time duration is 125 s. Meanwhile, further analysis also shows if we keep the inter arrival time of roads A, B, and C, and change that of roads D, E, and F from 1.7 to 3.4 s and the inter departure times at the three intersections on roads A, B, and C are equal to 0.6 s, the total performance of this is the best. Finally, according to the data collected from RFID readers and the best, second and third best traffic light durations generated from the simulation model, the automatic and dynamic traffic light control expert system can control how long traffic signals should be for traffic improvement.

10. KINETIC MODEL OF BATCH BIO‐METHANATION ON PREDIGESTED AGRICULTURAL WASTES USING HUMAN URINE

Authors- SUBODH KUMAR SAU, TAPAS KUMAR MANNA, APURBA GIRI*, PRASANTA KUMAR NANDI

Abstract- The effect of human urine on the biogas production from the predigested substrates were observed. The rice water, boiled rice, pumpkin waste, neem cake, tea waste, mustard seed cake, ground nut cake, cabbage and potato waste were used for the analysis in the predigested condition. Predigestion reduced the normal gas production time drastically. Per day gas production started at high rate and then gradually decreased as the reaction proceeded. The first order kinetic law for the production of the total gas was tried to fit the experimental date. The reaction rate constant was observed to be a function of the human urine. It was found that 150 ml urine addition gave more reaction rate. A first order generalized kinetic model was developed for the gas production and was seen that the proposed equation gave fairly good fit considering the diverse nature of the substrate.

Authors- VEER BHADRA, HARI KUMAR SINGH, GAURAV KAHNDELWAL, AMAN KUMAR

Abstract- There are wide varieties of system being used to control air pollution and scrubber system is one of those which are being used to control the emissions out of the exhaust of the diesel vehicles. Fuel burns in combustion chamber to give hazardous particulate emission out of the exhaust manifold. The objective of this experiment is to control the emission out of the exhaust by means of scrubber system used with water with different components in order to minimize the emission to maximum level. The basic principle behind this technique is absorption or particle wetting in which the solid particle is brought in contact of the liquid and the solid particle get absorbed in the colloidal form and get dissolved in the water or get settled down in the of colloidal form. The experiment was done on the Indian emission standards of hartridge smoke unit (65 HSU) used by “Pollution Under Control” Test van (PUC) used for diesel vehicles. The experiment was performed with a model which was connected at the rear of the exhaust of Chevrolet Tavera NEO 3 LS and 4-stroke diesel engine and then the readings were taken from the wet scrubber and the results were positive and again it was done by mixing calcium carbonate (lime stone) and the emission was minimized to too much extent. This technique is quite helpful in control of pollution from diesel vehicles or any 4-stroke C.I engine as these emit a lot of pollution out of the exhaust in the environment.

Authors- JAYASHREE A. GOTMARE, Dr. S. V. PRAYAGI

Abstract- The photovoltaic cells will exhibit long‐term degradation if the temperature exceeds a certain limit thereby decreasing the PV power in general and the efficiency of the said system in particular. This decrease is resulted first of all in dropping the open circuit cell voltage. The cell manufacturer generally specifies a temperature degradation coefficient & a maximum operating temperature for the cell. The cost of photovoltaic installation is mostly dependent on the PV array area. Therefore, in order to improve the cost effectiveness of the PV array power system, electric power generated by the PV array should be efficiently utilized. The purpose of this study is to improve the performance of a photovoltaic Panel by attaching a cooling system on the backside of the PV panel. The results are compared with Conventional systems. Experimental measurements for both with & without cooling system indicate that the Current developed by the photovoltaic panel with cooling system is higher as compared to the conventional panel. Also the power & the electrical efficiency of the combined system are higher than the traditional one.

16. AN EXPERIMENTAL INVESTIGATION ON SURFACE MORPHOLOGY OF MACHINED NANO‐COPPER OXIDE REINFORCED EPOXY COMPOSITE

Authors- HASAN ALAMERI, M. N. M. ANSARI

Abstract- This paper deals with machinability of nano‐copper oxide (nCuO) reinforced epoxy composite in terms of surface morphology with different composition using the computer numerical control (CNC) milling process. Composite’s surface roughness and dispersion of nCuO particles are the aspects of morphological research conducted. For the purpose of predicting the performance of machining parameters and the quality of products, surface roughness is the criterion analyzed. For the tests in this research, the evaluation of cutting parameters are spindle speed (SS), feed rate (FR), and depth of cut (DC). In order to study the main changes in texture of the machined surface and to make decisions on the optimal mixed‐level array of cutting parameters, Scanning Electron Microscope (SEM) and surface roughness measurement were conducted. Based on the analysis of variance (ANOVA) and signal to noise ratio (S/N) methods, it was determined that the SS and FR parameters have significant effects on the surface roughness. Hence, a better surface quality can be achieved by varying the level of cutting parameters. Moreover, the better surface roughness will be achieved by utilizing nCuO particles in the polymer matrix.

Authors- BRAHMAN SINGH BHALAVI, ARVIND KUMAR SINGH

Abstract- Non‐coherent detection provides simple receiver architecture then coherent detectors because it does not require carrier phase tracking. Also since non‐coherent detectors works differently than coherent it facilitates the application of multilevel noncoherent block coding which provides an effective error correcting capacity at higher coding efficiency. The further insight on Non‐coherent system shows that the coding efficiency can be further improved by increasing the minimum non‐coherent distance between the modulations symbols. This results the development of new modulation technique derived from MPSK and named as TAPSK (Twisted Amplitude Phase Shift Keying). The TAPSK may provide higher coding efficiency then traditional techniques for similar error correcting capacity when configured properly for specific block size and multilevel block codes. This paper presents the simulation and analysis of TAPSK with multilevel non‐coherent blockcodes (NBC) for development of efficient digital communication technique. Finally the simulation result shows that properly designed TAPSK configured with multilevel non‐coherent blockcodes (NBC) can achieve much better coding efficiency.

Authors- SHAHBAZ ALAM, NEHA SHARMA, BHUPENDRA SINGH BHATI

Abstract- Conventional boost converters that are used are not much sufficient to give soft switching as result switching losses is generated at turn on and off of switches. Due these losses the overall efficiency suffers. To overcome from the problem a new interleveled boost converter by utilizing zero voltage switching (ZVS) and zero current switching (ZCS) is introduced in this work module. It not only reduces input current and output voltage ripple but also it reduces the size and cost of the converter circuit by implementing a common soft switching method. The main achievement of this converter circuit is that a single switch can be used for both ZVS and ZCS characteristic to reduce switching loss and hence efficiency is improved. This converter topology also provides a large variation in load. Operation of this circuit is divided into two areas depending upon the duty cycle of the converter circuit. One operating area has been introduced in this module with its design parameter, theoretically analysis, experimental data and result after simulation is provided in this work module to get the feasible output. Simulation result on varying load is conducted during experiment and the result is provided. Comparison between various types of load on this circuit is also provided for better understanding.

Authors- A. JYOTEESH REDDY, A. ROHITH REDDY, P. VASUDEVANAIDU, M. BINDU PRIYA

Abstract- This paper deals with A New design of the D‐STATCOM for voltage harmonic suppression in distribution system. The DSTATCOM (Distribution Static Compensator) isused for Mitigation of Power Quality Problems like current harmonics under unbalance caused by various loads in distribution system. The D‐STATCOM consists of a three‐level Voltage Source Converter VSC), a dc energy storage device, a coupling transformer connected in shunt to the distribution network through a coupling transformer. The VSC converts the dc voltage across the storage device into a set of three‐phase ac output voltages. These voltages are in phase and coupled with the ac system through the reactance of the coupling transformer. Suitable adjustment of the phase and magnitude of the DSTATCOM output voltages allows effective control of active and reactive power exchanges between the DSTATCOM and the ac system. Such configuration allows the device to absorb or generate controllable active and reactive power. Hence to suppress the voltage harmonics with in IEEE standard limits. A new pwm‐ based control scheme has been proposed that only requires current measurements the operation of the proposed control method is presented for DSTATCOM. Simulations and analysis are carried out in MATLAB/SIMULINK with this control method for proposed systems.

Authors- NEHA RASTE, AMRUTA KULKARNI, GARGI BHANDARI

Abstract- Analysis of the current sericulture practices shows a clear need of automation. Strict control of optimum values of abiotic factors, like temperature, humidity and so on will contribute towards a significant change in the yield of silk. In view of this hypothesis, an Intelligent Sericulture plant automation system, using zone‐based cascade control of physical parameters is proposed in this paper. With ideal parameter values and a data repository of past implementations, the system intelligently implements the desirable changes using Artificial Intelligence techniques. The system comprises of a Data Acquisition Unit, a Computation Unit and an Actuation Unit. The DAU gathers data from respective zones in the rearing unit and channels it to the CU. The CU uses training data to determine the optimum yield curve using gradient descent algorithm. A shortest path from the observed parameter values to the optimum curve is calculated, which is the necessary change. The AU is responsible for triggering suitable actuators to implement this corrective action. This system has an edge over current sericulture practices as it ensures saving of time, optimal resource usage by the virtue of zones, lesser exposure to harmful conditions in the sericulture rearing unit and tighter control without expensive setup.

32. ADVANCED TOOLKIT FOR ON DEMAND ADHOC ROUTING

Authors- DHANASHREE TORADMALLE, JATIN BHOWAD, SIDDHESH JADHAV, KASHISH JAIN, SANJANA KESARKAR

Abstract- Advanced Toolkit For On Demand ADHOC Routing is a toolkit which can used to enhance existing toolkits available for on demand routing protocols. The existing toolkits aid us with a virtual look and feel of working of the routing protocol. However the existing toolkits do not provide a platform for a better in depth understanding of existing protocol. We thereby intend to provide a more visionary approach to user for better understanding and development of wireless ADHOC routing protocol. This can be done by generating a TCL script. The generated TCL script will help user to understand the code in a better way by executing the same in NS2 simulator.

33. ELECTRONIC PROPERTIES OF RARE EARTH COMPOUNDS

Authors- SURENDER, Dr. YASHWANT SINGH YADAV

Abstract- In the present work we have presented electronic properties such as homopolar gaps (Eh), average energy gaps (Eg), crystal conicity (fi) and conici energy of rare‐earth oxides (RE2O3, RE = rare‐earth materials) and sulfides (RE2S3). We have presented the expression relating the conici energy for these compounds with atomic number of constituent atoms. The conici energy of these compounds exhibit an inversely relationship with the average atomic number of constituent atoms (Zav). We have applied proposed relation on rare‐earth oxides and sulfides, which relation are entirely different from previous researchers and evaluate values are in better agreement with the experimental data reported so far.

34. SIGNIFICANCE OF COVARIANT DERIVATIVE IN FORMULATING GAUGE TRANSFORMATIONS
Authors-  Dr DEV RAJ MISHRA
Abstract-The invariance of the laws of physics under local symmetries predict the existence of a covariant derivative. The
various forms of interactions present in the nature appear as a natural consequence of this invariance.
