today, stock investment has become an important mean of national finance. apparently, it is significant for investors to estimate the stock price and select the trading chance accurately in advance, which will bring high return to stockholders. in the past, long-term trading processes and many technical analysis methods for stock market were put forward. however, stock market is a nonlinear sys...

Collaborative applications like video/audio conferencing, IP telephony, file sharing, collaborative work spaces, and multi-user games, having varied security requirements, require a secure and reliable group communication system to provide co-ordination among the processes. Peer to peer computing allows users to interact with each other and find and share resources without requiring a centraliz...

a r t i c l e i n f o a b s t r a c t In this paper, we propose a trust enhanced distributed authorisation architecture (TEDA) that provides a holistic framework for authorisation taking into account the state of a user platform. The model encompasses the notions of 'hard' and 'soft' trust to determine whether a platform can be trusted for authorisation. We first explain the rationale for the o...

social capital has received considerable attention in all branches of social sciences, and has recently been the focus in the field to explain about procreator elements. trust is one of the social capital elements and plays an important role in specifying consequences incidental to social capital. nearly two decades ago, robert putnam proposed an explanation of trust relying on associational li...

Recent advances in computer technology have motivated the automation of various functions of the inspection task, an important process in quality control. However, since purely automated inspection has limitations, hybrid systems, ones taking advantage of the superiority of humans in pattern recognition, rational decision-making, and adaptability to new circumstances, are preferable. To achieve...

Major standardization bodies developed and designed systems that should be used in vehicular ad-hoc networks. The Institute of Electrical and Electronics Engineers (IEEE) in America designed the wireless access in vehicular environments (WAVE) system. The European Telecommunications Standards Institute (ETSI) did come up with the “ITS-G5” system. Those Vehicular Ad-hoc Networks (VANETs) are the...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...
