A number of specifications formalisms have been developed (or applied) to support the abstract design of the behavioural component of the virtual environment interface. These formalisms subscribe to the philosophy that virtual environments should be viewed as hybrid systems which combine discrete and continuous behaviour. A significant deficiency in designing behaviour in this way is that the d...

Risk-driven approaches are dominant in secure systems design; these aim to elicit and treat vulnerabilities and the threats exploiting them. Such approaches, however, are so focused on driving risks out of system design, they fail to recognise the usefulness of failure as a vehicle for security innovation. To explore the role of failure as a design tool, we present the security premortem: a par...

Portable embedded systems are being driven by consumer demands to be thermally efficient, perform faster, and have longer battery life. To design such a system, various hardware units (e.g., level one (L1) and level two (L2) caches, functional units, registers) are selected based on a set of specifications for a particular application. Currently, chip architects are using software tools to manu...

Pain is a major concern in all intensive care units (ICUs). The proper assessment and management of pain is one of the main goals of patient care in ICUs. Improper evaluation of pain and its over or under treatment can cause significant problems in the process of patient management in ICU. Since most ICU patients are unable to communicate correctly with the ICU team and explain their level of p...

during the past decade, polymer nanocomposites have emerged relatively as a new and rapidly developing class of composite materials and attracted considerable investment in research and development worldwide.direct machining of polymers can be an option for personalized products and for manufacturing product samples. to obtain high quality products and reduce machining costs, it is very importa...

at this study, after designing and manufacturing a rotary tool, its machining parameters and their effects on surface roughness of aluminum alloy of al99 which  is one of the most consumable alloys in aerospace industry, is  studied and optimized. first, the rotary tool is designed and manufactred. then according to taguchi method, the experiments have been designed to record surface roughness,...

objectives: falling is a common problem among the elderly. falling indoors and outdoors is highly prevalent among the iranian elderly. therefore, identification of the contributing factors at home and their modification can reduce falls and subsequent injuries inthe elderly. the goal of this study was to identify the elderly at risk of fall, using the ‘home falls and accident screening tool’ (h...

Background: Although there are different tools in a coping context, lots of them are general and not applicable in every stressful situation such as transplant. Aim: The aim of this study is to develop and psychometrically evaluate a coping tool with kidney transplant in the Iranian context and culture. Method: In this sequential exploratory study, based on theoretical and practical definitions...

In most cases today information systems development involves the use of multiple development tools. The developer has the choice of many competing vendor tools to choose from, and the choices to be made are complex. Will the various tools work together, and which tool should be chosen for which task? This paper describes the development of a business simulation game, and the role various develo...

Model-based software prototyping enables effective construction of design tools for new system design approaches effectively in a very short time. In this paper, we show that explicit interface modeling is well suited to integrate such prototyped tools into design environments. In addition, we point out how our model-based generative approach supports evolution of prototypes very well. We prese...
