Most applications for location based services rely on a precise determination of the location of the mobile terminal. Especially in urban and indoor environments multipath propagation leads to very complicated scenarios without line-of-sight between the mobile terminals and the base stations. In these scenarios a localization technique based on simple delay evaluations and/or GPS is not accurat...

BACKGROUND Tumor thickness has been shown in oral tongue squamous cell carcinoma (OTSCC) to be a predictor of cervical metastasis. The postoperative histological measurement is certainly the most accurate, but it would be of clinical interest to gain this information prior to treatment planning. This retrospective study aimed to compare the tumor thickness measurement between preoperative, CT s...

Human behavior is sometimes determined by habit and other times by goal-directed planning. Modern reinforcement-learning theories formalize this distinction as a competition between a computationally cheap but inaccurate model-free system that gives rise to habits and a computationally expensive but accurate model-based system that implements planning. It is unclear, however, how people choose ...

Several important applications are placing demands on satisfactory characterization of the bi-directional interplay between kinetic and non-kinetic aspects in the mobility of people and commodities. Example applications include emergency planning, energy planning, and policy making, all of which require new holistic approaches for capturing the interplay. Accurate characterization of the interp...

Medical image segmentation is a key step and a preliminary stage in computer aided. The success of medical image analysis depends heavily on accurate image segmentation algorithms, so an accurate segmentation of medical images is primary in radiotherapy planning, clinical diagnosis and treatment planning. Therefore, it is a challenge and an unsolved problem. For this reason, medical image segme...

Objective: To study the protective effect of polyprenols on acute liver injury induced by CCl4 and D-Gal. Method: The acute liver injury model induced by 0.5% CCl4 in olive oil (10ml/kg) and D-Gal (800mg/kg, i.p.) in mice and rats respectively. 10, 40 and 160 mg/kg polyprenols was administered i.g., to study the protective effect for different doses of polyprenols, the therapeutic effect of eac...

Modern mine planning software plays a crucial role in the operation of many of the world’s mining operations and projects. Mine planning software provides the mining industry with a fast, accurate, cost effective and efficient tool in order to manage their business interests worldwide. Every aspect of the mining industry is today using some form of mine planning software. From exploration to re...

We begin by looking a t the central role of reasoning about change in planning and control. We then review some of the basic insights of control theory regarding the connection between observability and controllability, and consider how these insights should inform research in planning. We propose a decision-theoretic approach to planning that subscribes to a basic cycle of prediction, observat...

This paper studies the strategic planning process of an electronic business project. In today’s fast growing demand of electronic transactions, with more people accessing the internet worldwide, online shopping becomes an increasingly profitable but risky business. Selling online becomes a very competitive business and time is a critical factor in launching a web site for business. This paper i...
