Traditional approaches to requirements elicitation stress systematic and rational analysis and representation of organizational context and system requirements. This paper argues that the introduction of any computer-based system to an organization transforms the organization and changes the work patterns of the system’s users in the organization. These changes interact with the users’ values a...

There are many problems associated with requirements engineering, including problems in defining the system scope, problems in fostering understanding among the different communities affected by the development of a given system, and problems in dealing with the volatile nature of requirements. These problems may lead to poor requirements and the cancellation of system development, or else the ...

This paper examines the use of Bayesian Networks to tackle one of the tougher problems in requirements engineering, translating user requirements into system requirements. The approach taken is to model domain knowledge as Bayesian Network fragments that are glued together to form a complete view of the domain specific system requirements. User requirements are introduced as evidence and the pr...

Age has an important impact on body composition. The decreases of lean body mass and total body water accompanied by an increase of body fat are the most relevant changes leading to a reduction of the basal metabolic rate. Due to this and the fact that elderly people are generally less physically active, energy needs are lower. However, the requirements for most micronutrients are not reduced. ...

α-Synuclein is an abundant presynaptic protein that binds to phospholipids and synaptic vesicles. Physiologically, α-synuclein functions as a SNARE-protein chaperone that promotes SNARE-complex assembly for neurotransmitter release. Pathologically, α-synuclein mutations and α-synuclein overexpression cause Parkinson's disease, and aggregates of α-synuclein are found as Lewy bodies in multiple n...

The guidelines for Requirements Management have been documented many times formally but the actual problems faced by the software industry are quite different. Through research it is found that most of the software projects fail before they are completed or if they do reach completion their quality is not up to the mark. The aim of this Research study is to identify the loopholes in the require...

Some systems failures are due to defects in manufacturing and design, however that there are a significant number of system failures which result from errors, omissions and inconsistencies in the system requirements. We thus need methods to support a ‘safe’ requirements engineering process whose objectives are to specify system requirements such that system states which compromise safety are av...

Requirements elicitation is widely regarded as the most challenging activity within the scope of requirements engineering. The activity concerns the understanding of problems that a system should address, which later leads to the identification of system requirements. As an abstract process, its effectiveness is greatly influenced by the credibility and suitability of the stakeholders involved....

An integrative physiological model of the human circulatory system coupled with numerous subsystems is presented. The development of a human simulator to allow real-time interpretation of sensor data from home health monitoring devices and other biomedical sensors can be achieved using an integrated two model environment. This approach combines a foreground continuous time circulatory system mo...
