The power industry experiences revolution known as "Power Industry Structure Renewal" mainly due to increasing progresses in science and technology which will result in a gradual change in methods of communication with energy tools. Part of the revolution is the application of small generation units in power generation; units with lower generation volume capacity, and cost compared to the enor…

We develop a continuous linear multistep method using interpolation and collocation of the approximate solution for the solution of first order ordinary differential equation with a constant step-size. The approximate solution is combination of power series and exponential function. The independent solution was then derived by adopting block integrator. The properties of the method was investig…

Rotating disk flows arise in many areas of the electrochemical, biophysics, renewable energy systems and materials processing industries. Motivated by industrial applications, we examine a complex multi-physical coupled nonlinear heat transfer regime in the vicinity of a rotating disk incorporating thermal radiation, magnetohydrodynamics, and wall slip and variable thermophysical properties. A…

The Cyclic Voltammetric behaviour of copper(II)tetramethylethylenediamine systems with [Cu(II)]:[tmen]=1:10, 1:100 molar ratios, 1×10-3M Cu(ClO4)2.6H2O in aqueous 0.2M NaClO4 supporting electrolyte have been studied at pH5.0,6.50 7.20,9.10, 10.30, 10.85 and 11.20. The electrode process show quasi reversible one electron charge transfer preceded and followed by chemical reaction at glassy carb…

In this research, the construction of L-stable block hybrid Simpson’s methods for parallel implementation is discussed. Methods of orders 4, 5 and 6 are constructed with numerical experiments. The newly constructed L-stable methods for k=2 have shown to handle stiff equations while methods for k=3 and 4 do not handle stiff equations.

Optical sensors have wide range of application such as in medicine, astronomy, industry, and others. Sensitivity of symmetric three layered optical waveguide sensor is investigated. The proposed sensor consists of dielectric slab surrounded by metamaterial (MTM) cladding and MTM substrate. MTMs are new artificial materials which have simultaneously negative permittivity ε and negative pe…

Power generating technology based on renewable energy resources will definitely become a new trend of future energy utilization. The solar chimney power plant is a natural draft device which provides an upward momentum to the in-flowing air by firstly converting solar energy into thermal energy in the solar collector. Secondly the generated thermal energy is converted into kinetic energy in the…

In this paper we have proposed a specific method of simplification of three dimensional (3D) graphical models (polygonal meshes). Many applications in computer graphics require highly detailed complex models. However, the level of detail actually necessary may vary considerably. To control processing time, it is often desirable to use approximations in place of excessively detailed models. We …

In this work, a mathematical model to study the effect of various parameters like condenser surface area of heat transfer, humidifier area, heating capacity, type of packing material and flow rate of water on the performance of humidificationdehumidification desalination unit is used. It was found that, the productivity of the unit increases with the enlargement in surface area of heat transfe…

In this paper, a comprehensive numerical study is presented for the fully developed two-dimensional flow of viscous incompressible fluid through a curved duct with square cross section.
