To establish a new technique for in-situ measurements of high-level tritium, applicability of the new measuring technique that is based on utilization of X-rays induced by β-rays from tritium was examined for three physical states of tritium such as gaseous tritium, aqueous tritium, and solid tritium retained on the surface and/or in bulk of the tritium-exposed materials in fusion reactors. It ...

When developing a safety-critical system it is essential to obtain an assessment of different design alternatives. In particular, an early safety assessment of the architectural design of a system is desirable. In spite of the plethora of available formal quantitative analysis methods it is still difficult for software and system architects to integrate these techniques into their every day wor...

The Personalization of information has taken recommender systems at a very high level. With personalization these systems can generate user specific recommendations accurately and efficiently. User profiling helps personalization, where information retrieval is done to personalize a scenario which maintains a separate user profile for individual user. The main objective of this paper is to expl...

Many websites allow their users to personalize their profiles. As users subscribe to many personalization websites, such as social networks or search systems, each user owns different profiles, which are seldom compatible. Yet, there is a strong need for comparing the profiles of different users to discover shared interests, e.g., by integrating all user profiles into a global one. In this pape...

Data Warehouse-(DW) logical design often start with a conceptual schema and then generates relational structures. Applying this approach implies to cope with two main aspects: (i) -mapping the conceptual model structures to the logical model ones, and (ii) -taking into account implementation issues, which are not considered in the conceptual schema. This paper addresses this second aspect and p...

While existing studies on YouTube’s massive user-generated video content have mostly focused on the analysis of videos, their characteristics, and network properties, little attention has been paid to the analysis of users’ long-term behavior as it relates to the roles they self-define and (explicitly or not) play in the site. In this chapter, we present a statistical analysis of aggregated use...

Current UML Profiles for Business Process Modelling realise a narrow focus of the process, and capture the process flow on a low level of detail. They do not provide a comprehensive coverage of theoretical aspects. In this work, we have designed a UML 2 Profile for Business Process Modelling that provides two complementary perspectives, focussing on the business process context (e.g. goals, mea...

Semantic treatment of multimedia content, as well as of user preferences and interests, forms one of the most important topics in modern audiovisual content providing systems and opens a great variety of discussions among the research community. In this framework, extracting and combining profiling information about users and content is a challenging problem. This paper is part of our ongoing w...

eODL is the ITU component description language. Its current status is that it is defined textually and there are several transformation into other languages. There are also ideas about a graphical representation for eODL. In this article we present a graphical representation for some of the eODL language elements and discuss how such a graphical representation can be implemented using a high-le...
