Abstract

The job-shop scheduling problem is well known for its complexity as an NP-hard problem. We have considered JSSPs with an objective of minimizing makespan. In this paper, we develope a hybrid approach for solving JSSPs called GASA-JOSH. In GASA-JOSH, the population is divided in non-cooperative groups. Each group must refer to a method pool and choose genetic algorithm or simulated annealing to solve the problem. The best result of each group is maintained in a solution set, and then the best solution to the whole population is chosen among the elements of the solution set and reported as outcome. The proposed approach have been compared with other algorithms for job-shop scheduling and evaluated with satisfactory results on a large set of JSSPs derived from classical job-shop scheduling benchmarks. We have solved 23 benchmark problems and compared results obtained with a number of algorithms established in the literature.

Abstract

The present paper explores the mathematical molding of the wind turbine and its influence on the subsequent stages. Specifically, the paper investigate the modeling of gear train of the wind turbine and distinguishes the difference in the approaches usually used to establish the mathematical model which is later has a significant impact on the design, characteristic and performance of the modeled system. Mainly two commonly used approached for the gear train systems are analyzed and discussed. The main well know mechanisms are investigated in term of the most proposed assumptions to deal with the damping, shaft stiffness and inertia effect of the gear. This paper elucidates these concerns.

Abstract

A Voltage Controlled Oscillator (VCO) based on the new multiplication-mode current conveyor (MMCC) building block is presented. The oscillator is realized using a double integrator loop (DIL) where a linear frequency (fo) versus the control voltage (Vc) tuning characteristics with quadrature sinusoid signal generation in a range of 40  kHz ≤ fo≤ 700   kHz had been experimentally verified. The fo─ sensitivity is low while the frequency stability factor (Sf >>1) is high at satisfactory values of total harmonic distortion (THD ≈ 1.11%).

Abstract

Power transformers are interface between different voltage levels of essential importance. Because of the long manufacturing processes, transformers are one of the most critical and expensive equipment and so this is one of the reasons why condition monitoring becomes more popular. Monitoring systems as basis for diagnostics open the possibility for expanding the operating time, reducing the risk of expensive failures and allows several maintenance strategies. With different monitoring techniques, detailed informations about the transformer condition can be received and helps to minimize the probability of an unexpected outage. In this paper a methodology has been developed to use information derived from condition monitoring and diagnostics for rehabilitation purposes of transformers. The interpretation and understanding of the test data are obtained from the International Standards.

Abstract

Matlab/Simulink is known in a large number of fields as a powerful and modern simulation tool. In the field of building and HVAC simulation its use is also increasing. However, it is still believed to be a tool for small applications due to its graphical structure and not to fit well for the simulation of multi-zone buildings. This paper presents the development of a new multi-zone building model for Matlab/Simulink platform.

Abstract

A study of a parking lot lighting of a large manufacturing company in Iowa was implemented to evaluate monthly energy consumption. Mercury light bulbs with 227W ratings on the light poles were replaced with low power energy efficient LEDs to increase the overall efficiency. Additionally, a small scale wind turbine was installed to supply power to experimental light poles. Migration from the current gas bulbs to the LED light results yielded about 60% energy savings, while capital gains due to the generation of wind energy returned about 80% savings per month which recovered initial investments on the assets. The environmental impact of this study cannot be neglected and it also provided opportunity for STEM education in colleges and wind energy awareness in the society in Iowa by showing benefits from current experiments. Details of the methods and analyses should be particularly useful to urban planners because they show how standard references on investment in automobile parking should be modified to include efficient energy management. The authors proposed new way to limit the cost of energy consumptions and environmental pollution on wildlife and human health. Research implications are discussed in terms of the impact of natural features in urban areas for reduction of green house gas emissions and promoting alternative energy sources.

Abstract

This paper presents the implementation of indirect vector control of three phase Induction Motor using Hysteresis Band PWM current control and Synchronous Current Control in PSIM environment. In any machine drive system, current control directly influences both flux and torque developed directly. In Hysteresis current control method, actual current tracks the command current within a hysteresis band. There is no difficulty in current control tracking when CEMF is low, but at higher speeds, current controller gets saturated due to higher CEMF and hense becomes difficult to track due to which there will be a phase lag with respect to command current. All such problems are solved using Synchronous Current Control.

Abstract

This paper presents comparative performance of Buck Converter in both open as well as closed loop. With the help state equations Mathematical Model of Buck Converter is designed in MATLAB/SIMULINK. The obtained output response of open loop Buck Converter is sluggish, not optimum and consists of peak overshoots. PI Controller is used in closed loop model of Buck Converter. Output Voltage is compared with a reference signal, which then is processed through a controller (PI/Fuzzy). The obtained signal is superimposed with a carrier signal and given to switching device used. To further optimize the performance of Buck Converter and eliminate the peak overshoot present in output response, Fuzzy controller is used. Here Suguno type Fuzzy is used.
