Abstract—A skyline query finds objects that are not dominated by another object from a given set of objects. Skyline queries can filter unnecessary information efficiently and provide us important clues for various decision making tasks. Now a days, GPS devices and location based services are very popular and they can easily connect users and make groups. Conventional skyline queries are not su...

BACKGROUND Carers who wished to share their experiences with a national working group (the Consumer Group) prepared narratives as a way of identifying areas for discussion. METHODS The narratives were submitted to one author and subjected to thematic qualitative analysis. The themes were fed back to the Group for discussion. RESULTS Five main themes were identified: difficulties in obtainin...

Consider a group of users who would like to meet to a place in order to participate in an activity together (e.g., meet at a restaurant to dine). Such meeting point queries have been studied in the context of spatial databases, where typically the suggested points are the ones that minimize an aggregate traveling distance. Recently, meeting point queries have been enriched to take as input, bes...

Introduction:This study aims to investigate the attentional bias toward drug-related stimuli along with subjective craving after encountering such stimuli in methamphetamine users. Studies of cue reactivity have confirmed bias in attention and gaze to drug-related stimuli for most substances, but methamphetamine drugs are less studied by a direct measure such as eye tracking. Methods:Thirty ma...

Professor Donald Knuth’s TEX is a typesetting system with a wide user community, and a range of supporting packages and enhancements available for many types of publishing work. However, it dates back to the 1980s and is tightly wedded to 8-bit character data and custom-encoded fonts, making it difficult to configure TEX for many complex-script languages. "is paper will introduce X E TEX, a sys...

—In this paper, we propos a community-based harmonious media space for multiple users realizing ubiquitous virtual reality (U-VR). Although lots of work have been tried to develop smart spaces, they lack efficient management of media spaces for multi users. In order to overcome the problem, the proposed space enables the users to initiate community based on context and decide the level of perso...

Standard Functional Uniication Grammars (FUGs) provide a structurally guided top-down control regime for sentence generation. When using FUGs to perform content realization as a whole, including lexical choice, this regime is no longer appropriate for two reasons: (1) the uniication of non-lexicalized semantic input with an integrated lexico-grammar requires mapping \\oating" semantic elements ...
