Abstract:

With the aim of investigating a laser-welded dissimilar joint of TWIP and TRIP steel sheets, the microstructure was characterized by means of OM, SEM, and EBSD to differentiate the fusion zone, heat-affected zone, and the base material. OIM was used to differentiate between ferritic, bainitic, and martensitic structures. Compositions were measured by means of optical emission spectrometry and EDX to evaluate the effect of manganese segregation. Microhardness measurements and tensile tests were performed to evaluate the mechanical properties of the joint. Residual stresses and XRD phase quantification were used to characterize the weld. Grain coarsening and martensitic areas were found in the fusion zone, and they had significant effects on the mechanical properties of the weld. The heat-affected zone of the TRIP steel and the corresponding base material showed considerable differences in the microstructure andProperties..

Abstract:

An activated carbon adsorber was designed using the scale-up approach for packed column design. The design parameters were used in the fabrication of the activated carbon adsorber. Three tests were carried out with the fabricated activated carbon adsorber on a given borehole water and system filtered water containing some impurities that has resulted to bad taste, odour, turbidity and colour to test run the efficiency of the adsorber. The results showed that the carbon adsorber performed relatively well in removing the bad taste, odour, turbidity, color and iron..

Abstract:

This paper discusses the Sinusoidal Power Factor model, which is used in the electrical networks to get high efficiency and a low cost. There are several reasons that are very beneficial for improving the power factor. Some of these are economical and others are technical. For the technical reasons, power factor correction can help to reduce the voltage drop that is produced in underground cables or overhead lines at the transmission or distribution level. Also, it can reduce the load on electrical equipment which provides more capacity for equipment and can result in less copper loss. The economical side for power factor correction is represented by the reduction of the consumed power by compensating the reactive power and the decline of electric bills that are paid by customers. The excessive reactive power can be used in suppling inductive loads such air-condition and huge motors in factories.....

Abstract:

The surge in the global demand for energy has mandated numerous research to be carried out and still being carried out to find more efficient means of energy generation, management, and control of energy-consuming devices. This paper presents the design and construction of a microcontroller-based power outlet for energy monitoring and control with a mobile interface. This system is used in managing and controlling the consumption of energy in residential and non-residential houses. The characteristics components include a local embedded system, and a mobile application from which the user can set energy budget, and time when the system is required to switch off control to an outlet. The value of the energy budget is used by the system to ensure that supply is turned off immediately the budget is exhausted. Energy consumption data are also logged for the user in case of future references and analysis. The system was tested and results gotten were recorded. The system, if efficiently optimized could be used as a power scheduling system to manage major appliances for automatic and intelligent control..

Abstract:

Decimal floating point (DFP) arithmetic is important in various applications such as currency conversion, billing, insurance, banking etc., as it is able to produce precise decimal fractions and minimize manual calculations that perform decimal rounding. But binary floating-point arithmetic fails to provide correct decimal rounding and exact decimal fractions such as 0.10,0.0418. A multiplier is one of the main components in most digital and high-performance systems such as digital signal processors, microprocessors and Finite Impulse Response (FIR) filters etc. As technology advances, many scientists have tried and are trying to design multipliers which provide either of the following- high speed, low power consumption and hence less area or even combination of them in multiplier.....

Abstract:

The optimal tracking problem of descriptor time-varying continuous-time systems is studied. First, under the assumption of impulse controllability, it is shown that the original system can be converted to a reduced-order normal linear time-varying system and an algebraic constraint by the pre-feedback technique and the restricted system equivalent (r.s.e) approach. Second, the state augmentation technique is applied to construct an augmented system, in which the state vector consists of tracking error, auxiliary input (appearing in pre-feedback), the state, and its derivative of the normal system. This procedure transforms the tracking control problem into an optimal regulation problem of the augmented system. Third, by utilizing the related results of preview control theory, a controller for the augmented system is presented through letting preview length tend to zero. Meanwhile, a controller to solve the original problem is also derived from the controller for the augmented system. Finally, two sorts of numerical simulation methods are proposed for the time-varying descriptor continuous-time systems, which have been demonstrated to be effective by various examples..
