has developed a rigorous, technology-based learning environment that assists and assesses (hence, " assistments ") middle school students in Earth, Life, and Physical Science so that teachers can assess their students' skills rigorously, frequently, and in the context in which they are developing, namely, during instruction (Mislevy et al, 2002). Our program of work represents a significant adv...

This work presents a simulation-based tool for dependability-oriented design of Video on Demand (VoD) applications. The tool is organized in a layered architecture, so that simulation models can be built and detailed according to a hierarchical and modular approach. The higher layer, namely the Application Level, provides a variety of objects to rapidly model fundamental components typically fo...

The Web Services (WS) technology is currently gaining a wider and wider consensus. The features that characterise WSs, namely heterogeneity, distribution, openness, highly dynamic interactions, are some among the key characteristics of another emerging technology, that of intelligent agents and Multi-Agent Systems (MASs). In this paper we discuss the relationships between WSs and intelligent ag...

Tele-democracy is becoming increasingly important for local authorities in Europe. The EURO-CITI project aims to specify, develop and evaluate an integrated platform for two tele-democracy services, namely televoting for opinion poll petitions and tele-consulting. The technical developments are divided into those for operators at local authorities and those for citizens. The platform empowers o...

Cryptography techniques play an important role in modern world. The purpose of such techniques is to ensure the contents being unreadable to anyone except for parties who agreed to use some specific scheme. Moreover, current cryptography techniques provide more sophisticated services, such as message integrity, authentication, time stamping, and many others. There are two main approaches for cr...

introduction: telemedicine is defined as the ability to provide interactive health care by modern technologies and telecommunications which require related infrastructure and technologies. the aim of this study was to assess infrastructures of telemedicine at health centers, hospitals and clinics affiliated to shiraz university of medical sciences. method: this is a cross-sectional study conduc...

Background: Whether dysfunctional breathing (DB) subtype classification is useful remains undetermined. The hyperventilation provocation test (HVPT) used to diagnose DB. This begins with a 3-min phase of during which fractional end-tidal CO 2 (FETCO ) decreases that could be an assessment plant gain, relies on stores. Our aim was assess 1) whether the children suffering from different subtypes ...

The focus of this paper is on developing an early detection and warning system for near-field tsunami to mitigate its impact on communities at risk. This a challenging task, given the stringent reliability and timeliness requirements, the development of such an infrastructure entails. To address this challenge, we propose a hybrid infrastructure, which combines cheap but unreliable undersea sen...

developing of mobile technologies in the field of health create a new branch of e-health called mobile-health. the goal of this study is evaluation of communications infrastructure for mobile-health. for this purpose, fuzzy analytic hierarchy process is used for modeling and ranking the criterions and applications. three main criteria in mobile communication network namely, data transmission, a...
