IIJ03-03-02:ROOM COMFORT ANALYSIS FOR CEILING FAN AND EXHAUST FAN COMBINATION WITH COMPUTATIONAL TECHNIQUES
AUTHORS:Rakesh Kumar Kushwaha, Mr. Pankaj Mishra
Abstract—Weather has its own charm because it changes through season to season and week to months. And every shade of its, has joy as well some issues to the level of human comfort. Especially in hot and humid climates thermal comfort can become a problem for the occupants of many residential or commercial as well in academic buildings especially when they are not equipped with air conditioning system. This paper presents outcomes of an ongoing research work to investigate thermal comfort level in a space of NIRT room for ventilation condition along with ceiling fan using “computational fluid dynamics” (CFD) met. Actual measurements of the temperature distribution, relative humidity and air flow pattern were conducted. CFD simulations on the model of the house allow us to visualize the temperature distribution and air flow pattern and velocity in the house. During analysis it was observed that the thermal comfort in the house was found to be well outside the limits. CFD simulation was used to investigate the effects of using a ceiling fan, exhaust fan individually as well in combined condition, the ceiling fan installed in the middle of the room section and rotating at 140-280 RPM, where as an exhaust fan in front of the opposite wall to the main door, kept operational condition same for the both to develop a valid relation among. It was found that the fan produced swirling flow pattern in the room section resulting in a more uniform temperature distribution inside the room. However, there is a little improvement in the thermal comfort level in the house were observed with ceiling fan, and after, it was also observed that results of CFD simulations that the use of exhaust fans installed, has no significant effects on the thermal comfort level in the house. Hence the ventilation controlled with mechanical devices did not help improve the thermal comfort in the house being studied, the CFD simulation results can be used by building designers and engineers to further improved the level of thermal comfort in residential houses in hot and humid climates that are naturally ventilated.

AUTHORS: Vinod kumar dubey, Mr. Pankaj Mishra
ABSTRACT:-Weather has mobile property means it never remains stabilized through months over months and years after years. And every shade of its, has joy as well some issues to the level of human comfort. In winter peoples find some hot place to maintain their efficiency, and in summer they wish for some cool place to maintain their efficiency. But when it comes to hot and humid climates, thermal comfort can become a problem for the occupants of many residential or commercial as well in academic buildings especially when they are not equipped with air conditioning system. This paper presents outcomes of an ongoing research work to investigate thermal comfort level in a space of NIRT room using two different type of fan, using experimental data with “computational fluid dynamics” (CFD) met. Actual measurements of the temperature distribution, relative humidity and air flow pattern were conducted. CFD simulations on the model of the house allow us to visualize the temperature distribution and air flow pattern and velocity in the house. During analysis it was observed that the thermal comfort in the house was found to be well outside the limits. CFD simulation was used to investigate the effects of using a ceiling fan, wall fan individually as well in combined condition, the ceiling fan installed in the middle of the room section and rotating at 110-180 RPM, where as the wall fan to the walls. Keeping operational condition same for the both to develop a valid relation among thermal condition was assumed at 303 K. It was found that the ceiling fan produced swirling flow pattern in the room section resulting in a more uniform temperature distribution inside the room. However, there is a little improvement in the thermal comfort level in the house were observed with ceiling fan, and after, it was also observed that results of CFD simulations that the use of Wall fans installed, has lesser effects on the thermal comfort level in the house in comparison to ceiling fan. Hence the cooling controlled with mechanical devices helped to improve the thermal comfort in the house being studied, but not below ambient temperature. The CFD simulation results can be used by building designers and engineers to further improved the level of thermal comfort in residential houses in hot and humid climates that are naturally ventilated.

AUTHORS: Bhagwandas gadre, Mr. Pankaj Mishra
ABSTRACT:-Energy of natural resources such as sun, wind water, and biomass is in use by mankind since the very beginning of human life on earth. However, the mode of utilization has changed with time, commensurate with the change in our lifestyle. Rapid urbanization and industrialization, together with mankind’s quest for a luxurious life, have increased consumption that has touched 600 kwh in India, it is still low compared to per capita electricity consumption in developed countries. With the advent of computers, phenomenal growth in automobile sales and many other gadgets in our daily life, it is imperative to have a sustainable supply of energy. This necessitates the exploitation of all available energy resources and, among these; renewable resources are at the forefront. It is now an established fact that renewable energy can be an integral part of sustainable development because of its inexhaustible natural and environment – friendly features. Today several renewable energy systems and devices are in place to meet the day to day energy requirements for cooking, heating lighting, and electricity in rural and urban areas.

IIJ03-03-05:Fuel Cell energy System based DC to DC converter based on voltage control techniques
AUTHORS: Rambha Kumari, Pramod kumar Rathore , Mr. A,K. Jhala
ABSTRACT:-Multiphase interleaved boost DC-DC converters are typically used as a fuel cell power conditioner due to their low input ripple current. This paper presents analysis and design of a 2-phase interleaved boost DC-DC converter controlled by a PI Controller to enhance reliability and flexibility. The PI regulator for the output voltage control was tuned by the extended symmetrical optimum method to optimally operate in the fuel cell ohmic region with a guaranteed phase margin of 45° for the entire fuel cell voltage range. This paper presents a single switch based Integrated Boost series parallel fly-back converter has been presented. In the proposed converter the conversion efficiency of power is improved and the switching stress of the MOSFET switch is also reduced. In this converter there are two sub-stages. One is boost-fly-back semi stage which improves power transfer from input to load. The second one is dc-dc fly-back semi stage that provides good output voltage regulation. The bulk capacitors are connected in series with primary windings of 2:1 fly-back transformer which reduces switch stress and improves voltage regulation; the parallel connection improves the efficiency. Simulation results of the 1-kW, 120-V prototype converter connected with a PEM fuel cell stack closely agreed with simulation results in MATLAB/Simulink. The PI-based fuel cell converter has the potential for further development as a compact fuel cell generator or fuel cell electric vehicle with embedded online diagnosis and fault-tolerant operation.

IIJ03-03-06:Performance and analysis of Artificial Neural controller Based Wind Energy System
AUTHORS: Amrit Shaket ,Pramod kumar Rathore , Mr. A.K. Jhala
ABSTRACT:-In India, as a developing region, the introduction of sustainable energy presents an opportunity to provide a large number of people with a better source of energy resulting in a better quality of life while reducing the impact of global warming. Electricity is not available to many communities in India because the large capital investment required for the traditional electrical infrastructure has resulted in that a good reliable supply is only available in regions with strong economic and industrial activity and an existing grid infrastructure. The fact that renewable energy sources are also distributed sources offers an opportunity to save on the capital investment for the transportation and distribution of electricity. Though there are different renewable energy sources available such as photovoltaic and wind energy. Torque ripples and maximum power tracking form the most important problems facing Wind Energy Conversion System (WECS). This work presents modified toque ripple minimization algorithm for wind turbine using Artificial Neural Network (ANN) control. ANN which is designed to emulate the PI controller for closed loop operation under different wind speeds. Moreover inverter is used for connecting wind turbine generator to the grid in order to reduce Total Harmonic Distortion (THD).The MATLAB Simulink dynamic model developed wind turbine generator with ANN controller.

IIJ03-03-07:Design of 16 Instruction Area and Power Optimized ALU for Reconfigurable Logic
AUTHORS: Shikha Gupta, Prashant Chaturvedi and Monika Kapoor
ABSTRACT:-In this work, the design and synthesis of 16 instruction ALU is presented. The instruction set includes arithmetic instructions like addition, subtraction etc, logical instruction like logical AND, Logical OR, Shift and rotate instructions and BCD instructions. The hardware resources of proposed design are reduced by employing hardware sharing method, in which the same resources are used to perform distinct operations, viz increment operation can be performed with the same adder circuit used for addition operation with a very small additional circuit. Power consumption is a very important parameter for hand held devices, so in this work clock gating technique is employed to reduce dynamic power consumption. The proposed design is synthesizable and the target device used for its implementation is Kintex FPGA. The synthesis report depicts that the resource usage reduces by 2.2% and 12.2% reduction is power consumption is observed as compared to conventional designs where clock gating and hardware sharing techniques are not adopted.

AUTHORS: Omkar Chaurasiya, Prof. Kapil Soni
ABSTRACT:-A metro system is an electric passenger railway transport system in an urban area with a high capacity, frequency and the grade separation from other traffic. An elevated metro system is the most preferred form of metro structure due to ease of construction and less cost compared to other types of metro structures. An elevated metro system has two major components pier and box girder. In this project, study has been carried out on these two major elements. In the first part of this study, the performance assessment on designed pier by Force Based Design and Direct Displacement Based Design is carried out. The design of the pier is done by both force based design method and direct displacement based design method. In the second part, parametric study on behaviour of box girder bridges is carried out by using finite element method. The numerical analysis of finite element model is validated with model of Gupta et al. (2010). The parameter considered to present the behaviour of Single Cell Box Girder, Double Cell Box Girder and Triple Cell Box Girder bridges are radius of curvature, span length and span length to the radius of curvature ratio. These parameters are used to evaluate the response parameter of box girder bridges namely longitudinal stresses at the top and bottom, shear, torsion, moment, deflection and fundamental frequency of three types of box girder bridges.
IIJ03-03-11: PERFORMANCE ANALYSIS OF DTC WAVELET TRANSFORM BASED IRIS RECOGNITION
AUTHORS: RICHA SINGH , VIJAY TRIVEDI , DR. SADHNA K. MISHRA
Abstract: The Dual Tree Complex Wavelet Transform (DT CWT), a subset of discrete wavelet transform which generates complex coefficients to get their true and unreal parts by using a dual tree of ripple filters. This presents restricted repetitiveness (2m : 1 for m-multidimensional signals) and permits the change to provide close shift stability and directionally exclusive filters (properties lacking within the ancient wavelet transform) while preserving the typical properties of good modification and procedure eﬃciency with well-balanced frequency responses.The novel modify could be personalized to be shift invariant, and describe however to approximate the precision of this assessment and make necessary filters to achieve this. Specially DT CWT is desirable for pictures and other multi-dimensional indicators and summaries some applications of the change that take advantage of its specific properties, including denoising, sparse coding, and registration. To increase the precision of this projected method is implemented Iris recognition which is more accurate than the other existing methods of Iris recognition, however there are two methods used for feature remoting i.e. DT-CWT and low pass and high pass filters and the matching scores i.e. FRR and FAR of these two approaches are united in the given algorithm. In this results defines that the iris identification rate will be more accurate than the other iris recognition system.

IIJ03-03-12: To Simulate and Study of Voltage Sag Compensation in a doubly fed Transmission Line using a dynamic voltage Restorer by MATLAB
AUTHORS: Mr. MANOJ KUMAR GUPTA, PROF. HITESH LADE
ABSTRACT: Changing electric load and higher power transfer in a wide interconnected network lead stoserious, security lack in power system operations also if a sudden fault occurs there is a change in voltage profile which can lead to a sudden damage on load end. These voltage sags are compensated at generator side by various methods but at the load end there is a contingency. to avoid such sag at load side a mat lab model is proposed in which a transmission line is fed with two sources out of which one is a wind source and then is subjected to a 3 phase fault. the voltage sag which occurs is compensated in the other model at same instant when DVR Dynamic voltage restorer is programmed and is connected at the midpoint of grid. The results obtained shows that the voltage is compensated and profile is balanced, DVR uses the energy source in well timed manner and injects nessacary AC voltage to grid.
