The increased scope and complexity of tasks that people perform as part of their routine work has led to growing interest in the development of intelligent personal assistive agents that can aid a human in managing and performing tasks. One desired capability for such agents is that they be able to act proactively to anticipate user needs, opportunities and problems, and then act on their own i...

The Contextual Suggestion Problem focuses on search techniques for complex information needs that are highly dependent on context and user interest. In this paper, we present our approach to providing user and context dependent suggestions. The official evaluation scores for our submitted run are reported and compared to the overall median scores (across all 34 runs).

Once an effective HIV vaccine is discovered, a major challenge will be to ensure its world wide access. A preventive vaccine with low or moderate efficacy (30-50%) could be a valuable prevention tool, especially if targeted to populations at higher risk of HIV infection. High efficacy vaccines (80-90%) could be used in larger segments of the population. Estimated "needs" for future HIV vaccines...

BACKGROUND Especially for single older adults with chronic diseases, physical inactivity and a poor social network are regarded as serious threats to their health and independence. The Active Plus intervention is an automated computer-tailored eHealth intervention that has been proven effective to promote physical activity (PA) in the general population of adults older than 50 years. OBJECTIV...

qfd is a mechanism for translating the voice of customer into product through various stages of product planning, engineering and manufacturing that widely implemented in modern enterprises throughout the world. in parallel with welcoming to qfd, a lot of academic efforts have gone into improving and completing this method. now traditional methods for determining relative importance of factors ...

nowadays, the world is faced with diverse challenging issues which lead to the development of communities to discuss about the matter and provide solutions for them. academic research centers are then established to puzzle out the raised questions with reliance on expert opinions and studies in response to the current prevailing needs. islamic republic of iran blessed with knowledgeable academi...

In (key-policy) attribute based encryption (ABE), messages are encrypted respective to attributes x, and keys are generated respective to policy functions f . The ciphertext is decryptable by a key only if f(x) = 0. Adding homomorphic capabilities to ABE is a long standing open problem, with current techniques only allowing compact homomorphic evaluation on ciphertext respective to the same x. ...

CAMShift is a semi-automatic tracking algorithm, which needs tracking target to be calibrated manually, and can only track one single target at a time. Aiming at these problems, this paper proposes a vehicle tracking approach based on double difference method and CAMShift algorithm. This approach can automatically calibrate moving vehicles in traffic video and achieve multi-target tracking by u...

This paper introduces algorithms for target tracking in wireless sensor networks (WSNs) that enable reduction of data communication cost. The objective of the considered problem is to control movement of a mobile sink which has to reach a moving target in the shortest possible time. Consumption of the WSN energy resources is reduced by transferring only necessary data readings (target positions...
