Developing control schemes such as generalized predictive control and selforganized fuzzy logic control schemes to single-input single-output muscle relaxation process, has been validated in a series of clinical trials. The applications of these schemes to the multivariable anaesthetic model require many design parameters to be selected. This is due to the complex features that characterize such models. Among these features, the large patient-to-patient variability in model’s parameters is perhaps the most challenging one. This paper proposes a new internal model control (IMC) scheme to overcome this challenge with ease. Unlike the conventional IMC scheme, the proposed IMC scheme needs not a neural network used as a controller. Instead, its controller’s parameters are estimated based on its developed parametric neural network’s model; AutoRegressive eXogenous Local Model (ARX-LM). In short, the proposed IMC scheme has a delay-deprived ARX-LM network, and a controller that estimates its parameters based on the information of the developed delay-deprived model. Simulation results demonstrated the superiority of the proposed IMC scheme over self-organized schemes developed for the multivariable anaesthesia.

Abstract: Finite-difference time-domain (FDTD) method is used to investigate the characteristics of Cylindrical Dielectric Resonator Antenna (CDRA) over a soft ground plane. The effect of the soft ground plane on the input impedance, the radiation pattern, the circular polarization and the mutual coupling between two CDRAs are investigated. Compared with the smooth perfect ground plane, it’s found that the soft ground plane introduces a reduction in the backward radiation, an increase in the circular polarization beamwidth and a reduction in the mutual coupling between the two elements

In heavily populated areas, cell splitting used to increase the capacity of the cellular system. Cell splitting produces a cellular system with mixed cell sizes. Many previous studies assumed strength-based power control, which maintains received power at a desired level regardless of changes in the number of active users and in the amount of total other cells interference. However, with signal-to-interference ratio (SIR)-based power control systems, that maintain the received SIR at a desired level, the power level is a function of the above two variables. This study calculates the reverse link capacity of SIR-based power control system with mixed cell sizes.

It is useful to understand the effect of the irradiance and temperature on the solar cell and module performance, in order to estimate their I-V curves under various climatic conditions. This paper studies the effect of the temperature on the silicon and GaAs photovoltaic cells. Also in this study, the irradiance effects on both Si and GaAs solar cells will be presented. The study shows that, the rise in Voc, Pmax,and maximum efficiency with temperature of GaAs solar cell degradation was approximately 1/4, 1/3, and 1/3 for Si photovoltaic cell respectively. Si solar cell degraded more than GaAs solar cell. Therefore, this study demonstrates that using GaAs photovoltaic cells instead of Si solar cell is preferred for space applications.

In this paper, the coupled non-linear differential equations of the non-linear dynamical two-degree-of-freedom vibrating system including quadratic and cubic non-linearities are studied. The system consists of the main system and the absorber. The absorber is used to control the main system vibrations when subjected to multi external excitation forces at simultaneous primary and internal resonance. The method of multiple scales perturbation technique (MSPT) is applied throughout to determine the solution up to third order approximations. The different resonance cases are reported and studied numerically. Stability is studied applying frequency response functions. The effect of different parameters of the system are studied numerically. A comparison is made with the available published work.
