Approximate Bayesian computation (ABC) have become an essential tool for the analysis of complex stochastic models. Grelaud et al. (2009, Bayesian Ana 3:427–442) advocated the use of ABC for model choice in the specific case of Gibbs random fields, relying on a inter-model sufficiency property to show that the approximation was legitimate. We implemented ABC model choice in a wide range of phyl...

In a sustainable development context, the monitoring systems are essential to study the building energy performances. With the recent technology advances, these systems can be based on wireless sensor networks, where the energy efficiency is the main design challenge. To this end, most of the studies focus on low power Medium Access Control (MAC) protocols to reduce the overall energy consumpti...

We have constructed a system that supports unscripted social interaction between a player and virtual characters, where the participants pursue internal agendas and respond to one another in real-time. Our emphasis on unscripted interaction means that the characters must accept dynamically generated performance requests, while our concern with social interaction implies that the characters must...

This paper focuses on comparing performances of the selection combining (SC) diversity system in the presence of independent and correlated Ricean fading. For the case of correlated fading, we have presented closed form expressions for probability density function (PDF), and cumulative density function (CDF), at the output of dual branch SC. Also we have presented closed form expressions for sy...

We propose an improved class of estimators in estimating the nite population variance, using the auxiliary information. The expressions for the bias and mean squared error of the proposed class of estimators are derived up to the rst order of approximation. Some estimators are also derived from a proposed class by allocating the suitable values of known parameters and identi ed as particular me...

The aim of this article is to study the estimation of the parameter of ЭРланга distribution based on complete samples. The Bayes estimators of the parameter of ЭРланга distribution are obtained under three different loss functions, namely, weighted square error loss, squared log error loss and entropy loss functions by using conjugate prior inverse Gamma distribution. Then the minimax estimator...

Bluetooth can form many piconets and scatternets within close proximity. This network topology can cause self channel interferences. As the interference increases, the performance will be degraded. The effect of interference is critical when a lot of Bluetooth networks coexist. In this paper, the performances of Bluetooth networks under interference is analyzed and simulated using the concept o...

performance management is an ongoing process of recognizing, measuring, and individual and team performance development and aligning them with the organizational strategic goals (objectives). therefore the employee performance appraisal plays an important part in recognizing the strengths and weaknesses of the employees. on the other hand this task is done by individuals who are likely to make ...
