One of the major problems for search at Web scale is that the search results on the large scale data might be huge and the users have to browse to find the most relevant ones. Plus, due to the reason for the context, user requirement may diverse although the input query may be the same. In this paper, we try to achieve scalability for Web search through social relation diversity of different us...

Few nicotine dependence measures have been developed for smokeless tobacco (ST) users. Existing measures are limited by the requirement to rate the nicotine content of ST brands for which data is scarce or non-existent. We modified the Fagerström Test for Nicotine Dependence (FTND) for ST users, referred to this scale as the FTND-ST, and evaluated its characteristics in a population of 42 ST us...

The basic goal of any context aware system is to provide some proactive services adopting users' context. However, often in real life proactive behaviors create complex problems. The end users of the system have an implicit understanding of the system. If the context aware behavior of the system conflicts with their understandings and reacts differently from users’ expectation applications succ...

In this paper, we investigate the spectrum sharing requirements of secondary access to 960-1215 MHz band which is primarily allocated to aeronautical usage. Primary system of interest is distance measuring equipments (DME) aiding navigation of airplanes. We consider a scenario where indoor femtocells share the spectrum as secondary users. For the protection of the primary system, each secondary...

As the information flowing around in social network systems is mainly related or can be attributed to their users, controlling access to such information by individual users becomes a crucial requirement. The intricate semantic relations among data objects, different users, and between data objects and users further add to the complexity of access control needs. In this paper, we propose an acc...

In this paper we present CoWSAMI, a middleware infrastructure that enables context awareness in open ambient intelligence environments, consisting of mobile users and context sources that become dynamically available as the users move from one location to another. A central requirement in such dynamic scenarios is to be able to integrate new context sources and users at run time. CoWSAMI exploi...

Fuelled by the quantity of available online spatial data that continues to grow, the requirement for filtering spatial content to match mobile users’ context becomes increasingly important. This paper introduces a flexible algorithm to derive users’ preferences in a mobile and distributed system. Such preferences are implicitly computed from users’ virtual and physical interactions with spatial...

One of the major problems for semantic search at Web scale is that the search results on the semantic data might be huge and the users have to browse to find the most relevant ones. Plus, due to the reason for the context, user requirement may diverse even the input query may be the same. In this paper, we try to achieve scalability in semantic search through social relation diversity of differ...

To meet the increasing capacity demand on wireless networks, there have been intense efforts in the past decade on developing multiuser receiver structures which mitigate the interference between users in spread-spectrum and antenna array systems. While much of the research is performed at the physical layer, the capacity of networks with multiuser receivers and the associated resource allocati...
