performance optimization of a single-effect lithium bromide water absorption refrigerationsystem is the subject of this paper. first, the thermodynamic model of the system wasderived based on thefirst and second law analysis of an absorption refrigeration cycle with libr-water as the working fluid pair.then, the effects of different design parameters such as the generator inlet hot water temper...

To examine differences in control of gait between adults with Down syndrome (n = 12) and adults without disabilities (n = 12) two investigations were undertaken evaluating spatial and temporal gait parameters under varying and more complex task conditions. In the first experiment we compared gait parameters during a preferred walking speed and a fast walking speed. In the second experiment, we ...

In this paper, two configurations of previous work are extensively studied, namely pattern diversity and hybrid (pattern and polarization) diversity configuration. The first configuration provides the pattern diversity whereas second configuration provides both the pattern as well as the polarization diversity which helps to mitigate the multipath propagation effect. Both the configurations are...

This paper describes the design of an X-Band Magnetron to Linear Accelerator (LINAC) High Power Transfer System consisting in an 8 resonant cavities Magnetron connected to a dedicated vacuum Dielectric Window (DW). A main analytical design of devices is shown with compact formulas and is followed by numerical optimization. Electromagnetic and Thermomechanical coupling between these devices is d...

Lightweight materials and related concepts have been progressively focused on as an important design topic in automotive industries. Lightweighting is also considered as one of the key solutions to assist the overcoming of barriers to electrification. Global trends toward reduction of greenhouse gas emissions and fuel economy have also significantly increased the importance of this topic over t...

This paper uses ideas for stochastic search implementations of adaptive Bayesian models, such as those outlined in Denison, Malick and Smith (1998 a,b) and Chipman, George and McCulloch (1998a) and effectively applies these ideas to logspline density estimation and triogram regression. Interesting comparisons are made to assess the effect of greedy search, stochastic search and model averaging....

This paper discusses a novel technique to extract small signal equivalent circuit model parameters of GaAs MESFET device based on particle swarm optimization (PSO) technique. Three different variants of PSO namely basic PSO, Delta well quantum PSO (DQPSO) and Harmonic well quantum PSO (HQPSO) are implemented and compared. We find that these techniques extract the 16-element small signal model p...

stability and performance are two main issues in motion of bipeds. to ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. however, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. step length and step perio...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...
