Rich geo-textual data is available online and the data keeps increasing at a high speed. We propose two user behavior models to learn several types of user preferences from geo-textual data, and a prototype system on top of the user preference models for mining and search geo-textual data (called PreMiner) to support personalized maps. Different from existing recommender systems and data analys...
The Group on Earth Observations Biodiversity Observation Network (GEO BON) has been in formal existence for three years, following several years of design and discussion. It is the realisation of the biodiversity societal benefit area envisaged in the GEO System of Systems (GEOSS). GEO BON links together existing networks, each covering particular aspects of biodiversity or parts of the world, ...
Cooperative interval games are a generalized model of cooperative games in which the worth of every coalition corresponds to a closed interval representing the possible outcomes of its cooperation. Selections are all possible outcomes of the interval game with no additional uncertainty. We introduce new selection-based classes of interval games and prove their characterization theorems and rela...
The integration of high dimensional geo-visualization, geo-data management, geo-process modeling and computation, geospatial analysis, and geo-collaboration is a trend in GIScience. The technical platform that matches the trend forms a new framework unlike that of GIS and is conceptualized in this paper as a collaborative virtual geographic environment (CVGE). This paper focuses on two key issu...
Geo-tags provide an essential support for organizing and retrieving the rapidly growing online video contents captured by users and shared online. Videos present an unique opportunity for automatic geo-tagging as they combine multiple information sources, i.e., textual metadata, visual and audio cues. This report highlights various approaches (data-driven, semantic technology-based, and graphic...

 تخزين الطاقة هو احتجاز في وقت واحد للاستفادة منها آخر. الهدف من هذا العمل تحسين التخزين خزان الماء الساخن لأطول فترة ممكنة عن طريق ملء الخزان بوسائط مسامية مناسبة وأفضل مستوى تعبئة لمادة الطبقة المعبأة. تتناول هذه الورقة طرق الحرارية وتطبيقاتها مجال أنظمة تسخين المياه بالطاقة الشمسية ونظام الهواء الشمسي والمواد المستخدمة للحفاظ على تلك بشكل احترافي. أجريت التجارب للاستخدام المنزلي ...
Mobile location-based services usually access large geo databases via a wireless network. Sometimes it is useful to store a certain amount of geo objects on the mobile device. In this paper we present an approach to store geo data in an embedded SQL database on smart phones. Besides the storage of geometries in SQL tables we have to provide an efficient geometric indexing mechanism. We used the...
