The failure-detection and fault-correction are critical processes in attaining good performance of software quality. In this paper, we propose several improvements on the conventional software reliability growth models (SRGMs) to describe actual software development process by eliminating some unrealistic assumptions. Most of these models have focused on the failure detection process and not given equal priority to modeling the fault correction process. But, most latent software errors may remain uncorrected for a long time even after they are detected, which increases their impact. The remaining software faults are often one of the most unreliable reasons for software quality. Therefore, we develop a general framework of the modeling of the failure detection and fault correction processes. Furthermore, we also analyze the effect of applying the delay-time non-homogeneous Poisson process (NHPP) models. Finally, numerical examples are shown to illustrate the results of the integration of the detection and correction process.

Position awareness is a desirable feature for many applications of Wireless Sensor Networks. The Received Signal Strength Indication of a radio channel provides a feasible way of estimating distance between nodes because its use doesnpsilat require any additional hardware but a radio transceiver. The main drawback of using RSSI is its instability and interference susceptibleness noticed in real environments. This work shows an evaluation of a location algorithm for wireless sensor networks and presents a new calibration approach that substantially improves the trustworthiness in its results. The results show that adequately adjusted RSSI measurements can be successfully used for localization in wireless sensor networks.

A novel philosophy of secure mobile agent model which is based on trust model, risk evaluation and cryptography is proposed in this paper. Compared to current related research, our dynamic model can update in real time and is comprehensive for combining subjective and objective estimation. In addition, this model is broadly adaptive due to its flexibility. Trust and trust relationship are defined on secure problem as while as character of trust itself which are faced when analyzing mobile agent, and trust update function and recommender evaluate function which are already existent are improved. Finally, secure problems which might be brought by trust are discussed.

The objective of this study is to examine the most well known fuzzy regression approaches with respect to energy consumption estimation. Furthermore there is no clear cut as to which approach is superior for energy consumption estimation. This is quite important in developing countries such China and Iran severe fluctuation for energy consumption. Where classic regression approaches do not provide a suitable prediction. In the present study, monthly data for electricity consumption in Iran are studied from 1992 to 2004. For suitable anticipation of electricity demand fluctuations, sixteen fuzzy regression models are considered in this research. Each fuzzy regression model has different approach and advantages. Auto correlation function was applied for defining input data of each of these models. By using this technique a few combinations are considered for selecting the input of each model. After calculating each model, their outputs will be an estimated function of the rate of electricity consumption in Iran. For determining the rate of error of fuzzy regression models estimations, the rate of output of each model is compared with the actual rate of monthly electricity consumption in test data. Five types of errors are considered for each model. Also an analysis of variance and Duncanpsilas multiple range tests are performed to formally select the best fuzzy regression model. The results show that Peterpsilas model is out performs the other by considerable margin.

This paper presents a multicycles protocol for hospital automation (MP-HA) that works over multicast addressing and use a master-slave architecture. The protocol creates a segmented logical network based on multicast addressing associated to hospital beds. The objective of MP-HA is to ensure the determinism on network through medium access control mechanism increasing the transmission throughput. Thus, it creates a periodical environment making use of the parallel cycles which is called multicycles.

This study compares two case studies in the same industry which are recently adopting the virtual organization approach in order to improve the performance of their supply chains. One enterprise tries to integrate the market side by merging a brand owner whereas another one seeks for the integration solution to stop suffering from its insufficient control over the sub-manufacturing sites that each of them is registered as an independent firm during the corporate expanding period. By participating in the two projects, our research indicates different barriers of integrating toward the upstream and downstream supply chains and provides a mutual solution by building up the e-Fashion global supply chains. Similarities and dissimilarities of both cases towards the virtual organization approach are also addressed in this paper.
