Abstract:

The purpose of this paper is to present the efficiency of the application of the system dynamics simulation modelling in investigating the behaviour dynamics of the diesel engine complex system. The marine diesel engine is defined by a set of non-linear differential equations, i.e. by a continuous simulation model of a higher order and the so-called equations of state. At the same time, the simulation model is discrete as it strictly satisfies the chosen value of the fundamental integration time step DT. The paper presents a mathematical model of the system consisting of a marine diesel engine model, which forms the basis for designing a system dynamic qualitative model (mental-verbal, structural and schematic model) and a quantitative model (system dynamic mathematical and information simulation model). A scenario of mixed propulsion states has been presented. Parameters obtained with the aid of the hardware simulator Kongsberg ERS-L11 MAN B&W-5L90MC–VLCC Version MC90-IV have been used in conducting the simulation.

Abstract:

The use of Close Circuit Television has grown very popular over the last few decades as more countries contend with rising insecurity as well as the need for great accountability or transparency. Despite the fact that the growth of CCTV has been slowing down over the last few years, it is estimated that there are at least one billion CCTV surveillance cameras in use around the globe. Asia alone accounts for at least 65% of CCTV installations. CCTV deployment has aided the growth of state surveillance, crime prevention measures, as well as advancements of social monitoring and control (Kumar & Svensson, 2015). There has been increased criticism from members of the public and policy makers who feel that some aspects of CCTV usage infringe on the right to privacy which is considered very.

The BIW consist mainly two part i.e. top hat and flat plate which are joint together by using resistance spot weld. Spot welds made by resistance spot welding are used extensively in automotive engineering. However, owing to increasing demands in the use of advanced and lightweight materials, resistance spot welding has become a popular alternative for producing spot welds. Because of the complexity and uncertainties of resistance spot welds and thus formed structures, the finite-element (FE) modeling of the welds for Dyanamics analysis is a research issue.

Abstract:

PV based traction systems employ DC-DC convert- ers for boosting the PV output voltage to adequate levels. Modern traction applications requires high voltage levels (500V to 750V) and hence, conventional boost converters are inadequate. In order to establish an efficient traction system, a high step-up gain interleaved DC-DC converter is presented. A high step-up gain interleaved DC-DC converter is designed by combining the switched capacitor and regenerative boost (SCRB) configuration. Since the switched capacitor and regenerative boost operations take place simultaneously, the voltage gain and efficiency is improved. In addition, interleaving reduces ripple content, which helps to elongate the lifetime of traction motors. Moreover, it offers low switching stress across the semiconductor....

Abstract:

Semi solid metals forming is a technique for metals processing that involves semi-solid fabrication and forming between the liquefaction and solidus states. For successful forming, the semi-solid metal micro structure has to consist a globular grains of solid in the liquid matrix. This behavior is called thixotropically where when the metal is sheared, it moves and when it is at rest, it solidify again. There are two main categories; rheo-routes and thixo-routes. The rheo-route is one process step where the semi-solid metal slurry is prepared with globular grains microstructure by stirring and cooling, which is pressed into die for shaping without solidification stage. The thixo-route is the process where the melted material is passed through solidification stage which tend the material in the form of a billet....

Abstract:

A high voltage gain non-isolated boost converter with switched inductor is proposed in the paper. The converter is constructed by adding an additional switched inductor to a conventional three-level-boost (TLB) converter. Conventional TLB converter is widely used in power electronics systems because of its simple structure. When compared with the conventional boost and TLB converters, the non-isolated boost converter can achieve higher voltage conversion ratio with reduced voltage and current stresses in the switches. A special feature of the converter is to automatically balance the output voltages for an unbalanced load without the need of any additional control strategy or auxiliary circuit. The converter is more suitable than the traditional TLB converter for high step-up applications. The performance study of converter is carried out with MATLAB/SIMULINK R2017a. From the analysis it is observed that the performance of the converter is improved. The converter has a maximum efficiency of 96%.

Abstract:

The abstract should summarize the content of the paper. In the present situation, biomedical waste is a big problem. When the number of hospitals and health-care facilities grows, so does the amount of biomedical waste generated. With the increase of medical care, the amount of biomedical waste produced every day is growing. And different types of waste are managed differently (reused, recycled, and reduced), Not just that, but poorly disposed waste can be detrimental to the atmosphere as well as poisonous to those who come into contact with it when disposing or handling medical waste. Thus we are developing the automatically open color coded dustbin and when the dustbin is full at that time buzzer will get the sound moreover using the GSM module to transmit a message to the hospital management system updating the dustbin status.

Practical experiments are a vital part of science curriculum. Theoretical knowledge is important but practical acquaintance helps in acquiring deeper insight into the details of the subject and boosts the overall learning mechanism by acting as a catalyst in the process of conceptual understanding. For Gen Z learners, there is a need of complete overhauling in terms of pedagogy. With the advent of technology, the use of simulation tools has proved to be an important methodological approach for a better understanding of the practical papers taught to science students at undergraduate level. In this paper we demonstrate the use of a mathematical program to complement the concepts acquired in laboratory work through an example. We have used an open source software scilab along with Wolfram Mathematica cloud that enables the students to learn the concept without any financial burden.

Abstract:

A 200W/1 MHz high voltage-gain two-phase bidirectional DC-DC converter can be operated in the charging mode from the DC bus to the battery and in the discharging mode from the battery back to DC bus. An interleaved topology is being used in the two phase circuit, along with a clamping capacitor that helps to reduce the voltage stress of switches. Even at very high voltage gain, voltage stress of switches can be controlled by setting the number of phases needed. Irrespective of the number of phases, the voltage stress across switches can be reduced by adding a combination of a LC2 and a switch. The simulation and analysis of the high gain bidirectional DC-DC converter with reduced voltage stress for the forward mode (Buck mode) and the reverse mode (Boost mode) are carried out under the condition of D ≤ 0.5. The input bus voltage is considered to be 400 V to get the output battery voltage as 35 V. In the modified reduced stress converter, voltage gain is improved. The peak efficiency is increased to 97%. The performance study of the converter is carried out in MATLAB/SIMULINK R2017a environment. Switching pulses were generated using TMS320f28335 microcontroller..

Abstract:

In far-off areas like towns, islands, and sloping regions, there is a chance of continuous force disappointments, voltage drops, or force variances because of lattice side deficiencies. Framework-associated sustainable power frameworks or miniature matrix frameworks are ideal for such far-off areas to meet the neighborhood basic burden prerequisites during lattice side disappointments. In sustainable power frameworks, sun-based photovoltaic (PV) power frameworks are available and crossover PV-battery frameworks or energy stockpiling frameworks (ESS) are more equipped for giving the uninterruptible capacity to the neighborhood basic burdens during lattice side shortcomings. This energy stockpiling framework likewise improves the framework elements during power variances.

Abstract:

The powers between two DC sources are transferred in either direction by using bidirectional DC-DC converters (BDCs). Such converters are commonly used in applications, such as fuel-cell hybrid power systems, hybrid electric vehicle energy systems, battery chargers, photovoltaic hybrid power systems, and uninterrupted power supplies. Here, a new bidirectional DC-DC converter with high voltage gain in both buck and boost operating modes is proposed. This new BDC is obtained by replacing all the diodes in the Single Switch Transformer less DC-DC converter that uses L2C3D2 network, with switches and controlling their pulses in buck and boost modes. It has the advantages of a lower voltage stress across the power switches, a wide voltage-gain range, and an absolute common ground. The operating principle, the voltage and current stresses on the power switches, the comparisons with the other converters and the controller design are also mentioned. The simulation is carried out using MATLAB/SIMULINK R2017a. Using FPGA controller, the pulses for the switches are generated and they are driven using TLP250.

Abstract:

The current paper includes numerical analysis for flow and heat transfer co-efficient parameters of elliptical and circle pin fin on a wedge duct. Reynolds-averaged Naiver–Stokes equations are coupled with k-e turbulent model coupled and hence analysed. The disparity of flow field variables on pressure drop and amount of heat transfer was obtained for Reynolds number of 10,000 – 50,000 in steps of 10. Two different shapes of pin fins are analyzed with two different boundary conditions for Five Reynolds number namely, circular and elliptical pin fins. The results of two different inline pin fins were justified with the empirical data with change in end wall and pin–fins area-averaged Nusselt number with the variation in the Reynolds number. The numerical results of circular pin fin agree well.
