Fundamentally, the development of software applications involves dealing with two distinct domains: the real world and software domains; the two converge at the point where a software application is used to make an unsatisfactory real world situation into ...
NOVELTY - An event received by a node, from a neighboring node, in the network is evaluated, to determine whether the event satisfies predetermined security test. The entry associated with the neighboring node in the topology data is modified, if the event ...
Early requirements of information systems are often understood in terms of the elicitation of stakeholders high-level goals to be supported by the system under discussion. Stakeholders goals are considered as the ultimate explanation of requirements. It is ...
The controller synthesis paradigm provides a general framework for scheduling real-time applications. Schedulers can be considered as controllers of the applications; they restrict their behavior so that given scheduling requirements are met. We study a mo ...
This paper introduces four sociological concepts which we argue are important for the creation of autonomous social agents capable of behaving and interacting realistically with each other as virtual humans. A list of functional requirements based on these ...
Current goal-oriented requirements engineering methods focus on the definition of optimal requirements that an information system needs to support in order to help its stakeholders to achieve their goals. But, the lack of systemic reasoning and disregard f ...
This paper describes an on-site developed interface amplifier and timing generator unit for the control of operation of an X-ray spectrometer, aimed at obtaining off-line time-resolved pulse height analysis spectra, using at single channel of a digital tra ...
Standardization experts in object modelling are having difficulties with defining the concept of role; for example, they are not sure of whether role is a type or an instance concept. This issue is a source of confusion in the UML standard, and prevents IS ...
The polarimeter system for ITER features 10 viewing chords covering almost the full poloidal cross section of the plasma in a fan-like arrangement. The 10 laser beams all enter the plasma via 150 mm diam penetrations through the diagnostic plug at the low- ...
This report describes the design of a Replication Framework that facilitates the implementation and com-parison of database replication techniques. Furthermore, it discusses the implementation of a Database Replication Prototype and compares the performanc ...
