Magnetic Levitation System is one of practical examples which faces some nonlinearities behavior. Such systems require special types of controller parameters consideration for accurate results. In this paper, the process of tuning is to determine the system poles and getting them away from the instability region using state feedback (SF) controller methodology. The resulted controllable system parameters are estimated using LQR controller. Since the desired goal is to minimize vital parameters in the system behavior like the steady state error, settling time, raising time of the system and

Committing robotics with artificial intelligence becomes mandatory collaboration with distinct environments. Omnidirectional Wheeled (Omni-WD) mobile robots are one of the robots that interact with humans in various circumstances, where it is important to function effectively and accurately. In this paper, the distinction of a 3WD-Omni model and control using machine vision is demonstrated. The use of fractional order (FO) calculus has been stated to increase the degrees of freedom of the controller over the integer ones. Hybridization of FO control and metaheuristics optimization is reported

The use of modeling and simulation as a decision aid tool has been widely recognized in the field of production engineering. In this work, modeling and simulation is used to examine, analyze, and recommend improvements for the performance of an existing assembly line within a manufacturing facility. Several key performance indicators (KPIs) are determined to evaluate the performance of the assembly line under study. With the aid of Maynard Operation Sequence Technique (MOST) and Line Balancing methods, two improved systems are recommended to enhance the performance of the line under study

This work assesses the economic sustainability of industrial factories in Egypt based on the Analytical Hierarchical Process (AHP). The authors designed an economic sustainability index calculator (ESIC) using Unified Modelling Language (UML) and implemented the software using Visual basic of Applications (VBA) tool to the code the program. UML was used for the system analysis and design only, giving an insight to the system architecture. The manual method of calculating the economic sustainability index is included in this research and verified by using the designed ESIC. The categories of

A blend of poly 3-hexylthiophene (P3HT) and [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM) is used as a photoactive layer for simulating a bulk heterojunction organic solar using general-purpose photovoltaic device model (GPVDM) software. The optical and electrical performance of the cell had been analyzed by changing the thickness of each layer and substrate material over a range of operating temperatures from -10 °C to - 40 °C. The flexible device exhibits higher PCE compared to a rigid device. The performance of the device was studied using transient simulation at different operating

In this paper, we introduce active material for an organic solar cell with a modified composition. A combination of P3HT: PCBM with parallel vertical LiF cylinders formulate the active material structure. The collection efficiency in the active material reaches 92.2%. The operating wavelength where the maximum collection efficiency occurs is adjusted and matched with the wavelength where the maximum irradiance of the solar spectrum occurs. The absorption per unit volume of the new structure is 80.4 μm-3 while the blank structure is 75.07 μm-3. The net absorption magnitude for the required

This study aims to utilize bagasse waste produced from the sugar cane industry to manufacture single-use tableware such as plates and cups as a potential alternative to Styrofoam and plastic cups and containers. This will reduce the environmental hazardous results from packaging products. Unlike traditional plastics and Styrofoam which can take hundreds of years and require high temperature to degrade, these eco-friendly containers from bagasse take approximately 60 days to degrade and break down. In this research, potato peel starch and glycerol were added to bagasse pulp to improve both

This paper aims to conduct a feasibility study of producing fuel from plastic waste. It is a suggested approach to deal with the huge production of synthetic plastic around the world, so as to avoid its accumulation in landfills and the depletion of resources. Several types of research have addressed the conversion of plastic waste into energy, and in this study the authors focused on using pyrolysis to convert plastic to liquid oil. Accordingly, the volume of the waste was reduced significantly, and the produced liquid oil had a high calorific value in comparison to fossil fuel. The authors

Meta heuristic algorithms are very important methods, they used mainly in solving combinatorial optimization problems. They are stochastic in manner and simulate the behavior of any population of particles. Meta heuristics algorithms try to find optimal or near to optimal solution when solving complex optimization problem. In this paper two modified emperor penguins colony optimization algorithms MEPC1 and MEPC2 were developed. Original Emperor Penguins Colony (EPC) algorithm simulates the behavior of emperor of penguins, two modifications are done to the original EPC, Archimedes and

The globalization and rapid industrialization of any country is a function of availability of electricity in desired quality and quantity. Nigeria and Egypt are the most populated countries in West and North Africa respectively with incredible energy resources both renewable and non-renewable. Yet, the former is highly energy deficient when compared to the later. In recent time, the appropriate authorities have tried earnestly to reform the sector with the intent to improve the unpalatable situation through the liberalization of the vertically integrated structure of the power industries.
