User Requirements

This paper describes key concepts of composable FORCEnet, which is the US Navy's operational construct architectural framework for naval warfare in the information age. It describes the concepts and architecture, in several categories: 1) systems and general software engineering; 2) networks ; 3) intelligent software; and 4) network security. The engineering approach to implement FORCEnet is an example of rapid prototyping in which the requirements of the users reviewed periodically and frequently with considerable user input. This method, which captures and implement changes in user requirements, strongly supports the development of relevant and useful systems with up-to-date technology that will be responsive to the users' rapidly changing needs.

All proposals for quantum key distribution re- quire that the parties have access to an authenticated chan- nel. Therefore, a key pre-distribution system is needed to provide authentication for the users. In this paper we pro- pose an ecient scheme for key pre-distribution and identi- cation for users with quantum channel. Our proposal uses quantum one-time-pad for implementing a quantum

Car navigation systems are discussed in this study in terms of knowledge discovery, data mining and data quality. Since data, information and knowledge are inseparable levels of human cognition, integration of these methods aids to understand the real-world patterns for car navigation systems and add value. The car navigation system is multi-purpose, multi-scale, multi-temporal and varying users requires different levels of abstraction and visualization of spatial data and information. Hence, the data discovered, mined and the quality should be visualized on timely manner, without leading any confusing and for varying users and purposes. In this concept whole process was evaluated with in the context of research questions asked by Gahagen et.al (2001), where visualization problems and proposal for them were emphasized.

AbstractMore than half a million people in Europe live on chronic renal re-placement therapy by hemodialysis (HD). Though arteriovenous fistulas are the preferred vascular access (VA) method of connecting a patient’s circulation to the artificial kidney, VA dysfunction is the major cause of morbidity and hospitalization in HD patients. The ARCHproject has been initiated to tackle this problem by delivering

Modern C3I systems are best described as semi-automated data management and decision systems over which human operators exercise supervisory control. The effectiveness of such systems is heavily dependent on the design for human-computer interaction (HCI), an important aspect of which is the visual display interface. Current Department of Defense policy mandates consideration of such human factors issues at an early

In this paper we present a complete reference framework for the operation of a Trusted Third Party (TTP) as an organisation within a medical environment. The objective is to form an intermediate reference model, to which the TTPs will conform, towards the full compliance to the ISO-9000 quality standard. There are two dimensions of quality in respect of a TTP,

In this paper we present a complete reference framework for the operation of Certification Service Provider as an organisation. The objective is to form an intermediate reference model, to which the CSPs will conform, towards the full compliance to the ISO-9000 quality standards. There are two dimensions of quality in respect of a CSP: The first quality dimension regards the

Nowadays, more and more surgical interventions are carried out in Minimally Invasive Surgery, to make the post-operative constraints less painful for the patient. Actually, new surgical tools or medical products are designed after informal discussions between surgeons and designers. The user requirements documents are the main document used by the mechanical designers to design and improve the product. Medical terms,

Abstract: Daily operation and maintenance tasks are needed to guarantee the correct performance of constructed wetlands. The definition of these activities is a complex task since these actions vary according to the characteristics of each facility. To support the definition of these ...

Summary Nowadays QoS (Quality of Service) architectures have been required to support most of distributed applications, particularly in wide environments like the Internet. In this context, it aims to be more interesting to offer services according to user requirements and expectations. We will be able to talk about Quality Driven Delivery (QDD) when we consider the users expectations in terms of non-functional requirements like cost. In this paper, we propose a framework to support QDD in distributed multimedia systems that enable QoS specification, QoS mapping and more generally QoS decisions in order to provide resources allocation and adaptation. We focus on the quality information management to support QDD while proposing an UML diagram for QoS information model.

Ubiquitous computing environments are intelligent environments that have a wide array of embedded sensors and other artefacts that provide information regarding the current state of the physical environment. Utilisation of such information, known as context information has the potential to alter the natural surroundings of users in order to adapt the environment to suit the user's needs and assist in

Today although a contemporary house or apartment is built with new materials according to technology and regulations to provide a satisfactory microclimate within the building, it is difficult to say they are successful comparing with a house that is constructed with traditional methods and materials even built by a non-architect. In this paper microclimatic elements of traditional Diyarbakýr houses are

Debugging data races in parallel applications is a difficult task. Error-causing data races may appear to vanish due to changes in an application's optimization level, thread scheduling, whether or not a debugger is used, and other effects. Further, many race ...

In multimedia cellular CDMA networks, different receive power levels are set based not only on different user requirements such as data rate and bit error rate but also on interference from other cells - this phenomenon is referred to as receive power control (RPC). We investigate how dynamic base station assignment (DBSA) can be used to adjust RPC (i.e., DRPC). It is shown that DBSA coupled with DRPC can improve the system performance in terms of minimizing total mobile transmit power. In effect, the above approach attempts to operate the wireless network approximately with equal total received power. Numerical results are presented to show the advantage of using DRPC.

The most important part of alarm systems is the rules set that allows triggering alerts. We propose a generic rule design framework which can support the design and the implementation of alerts for drug prescriptions or their pharmaceutical validation. Our approach takes into account two important criteria, which represent two real challenges for the system designers. First, the developer needs to identify and model both users’ requirements and business processes in which the alarm system works. Second, the developer needs to model the knowledge associated with the decision rules with an appropriate language. We show how the Unified Process helps to model the business process for pharmaceutical validation. Knowledge representation benefited from use of SBVR, a language dedicated to rule representation within an object oriented framework. After a successful implementation of a prototype we plan to integrate such system within the hospital information system of the Georges Pompidou hospital.
