for a long time, culture has been an influencing parameter in negotiations. growth of international trades and business competitions has increased the importance of negotiations among countries and different cultures. developing new technologies, particularly the use of artificial intelligence in electronic trading areas, has provided us with the application of intelligent agents to resolve cha...

Software reliability is an important characteristic for most systems. A number of reliability models have been developed to evaluate the reliability of a software system. The parameters in these software reliability models are usually directly obtained from the field failure data. Due to the dynamic properties of the system and the insufficiency of the failure data, the accurate values of the p...

-The paper presents an overview of two recently developed simulation support tools, namely the optimization tool and the sensitivity analysis tool, and demonstrates their use for tuning and analyzing the control system of a static compensator (STATCOM). The optimization tool is used for adjusting the gains and time constants of the control system in order to improve the transient behavior of th...

The system performance plays a great role in analyzing the characteristics of optical wireless communication link. This paper describes the effect of BIT ERROR RATIO and QUALITY FACTOR in communication system. The effect of diameter antennae with received power and distance is also analyzed in this paper. The value of antennae diameter varies from 20 cm to 40 cm and distance between satellites ...

We present a unified R software ivmodel for analyzing instrumental variables with one endogenous variable. The package implements a general class of estimators, k-class estimators, and two confidence intervals that are fully robust to weak instruments. The package also provides power formulas. Finally, the package contains methods for sensitivity analysis to examine the sensitivity to the the i...

The effect of the sensitive area of the two-port resonator configuration on the mass sensitivity of a Rayleigh surface acoustic wave (R-SAW) sensor was investigated theoretically, and verified in experiments. A theoretical model utilizing a 3-dimensional finite element method (FEM) approach was established to extract the coupling-of-modes (COM) parameters in the absence and presence of mass loa...

Global sensitivity analysis techniques are better suited for analyzing input-output relationships over the full range of parameter variations and model outcomes, as opposed to local sensitivity analysis carried out around a reference point. This article describes three such techniques: (1) stepwise rank regression analysis for building input-output models to identify key contributors to output ...
