This paper presents the general architecture of the ZeeRO mobile robot, with an emphasis on its main modules: navigation, sensors and data processing. The interface with the Player server that allows simulations in 2D (Stage) or 3D (Gazebo) is also presented. The last part of the paper presents some applications for this mobile robot, some of the performed tests and also some of the future plan...

This paper gives an outline of the targets, achievements and future plans of the recently started MoMuSys extension work called "New Tasks for MPEG-4". It consists of three different parts: (1) development of new algorithms for MPEG-4 Version 2; (2) development of a semi-automatic video object generation tool for content creation purposes; (3) development of an MPEG-4 based mobile virtual confe...

Standard procedures of logic programming do not take into account program updates. If the given program is updated during or after the evaluation of a query, the answer to the query is not correct any longer. This paper shows how to use Dynamic SLDNF (DSLDNF), a new extension of SLDNF, which works under changing logic programs in order to construct plans for robot navigation in dynamic environm...

This paper presents a method of solving planning problems that involve actions whose effects change according to the situations in which they are performed. The approach is an extension of the conventional planning methodology in which plans are constructed iteratively by scanning for goals that are not yet satisfied, inserting actions to achieve them, and introducing additional subgoals to be ...

We introduceAk, an extension of the action description languageA (Gelfond & Lifschitz, 1993) to handle actions which affect knowledge. We use sensing actions to increase an agent’s knowledge of the world and non-deterministic actions to remove knowledge. We include complex plans involving conditionals and loops in our query language for hypothetical reasoning. We also present a translation of A...

agricultural production is influenced by different political, economic and environmental factors. various factors influence production, affecting the income of farmers and even in some cases increasing their vulnerability. continuation and expansion of economic activity in this sector requires appropriate risk management policies to be promptly and appropriately applied. one of the oldest strat...

In DataCell, we design streaming functionalities in a modern relational database kernel which targets big data analytics. This includes exploitation of both its storage/execution engine and its optimizer infrastructure. We investigate the opportunities and challenges that arise with such a direction and we show that it carries significant advantages for modern applications in need for online an...

: With the fast development of the E-commerce, it becomes critical to set up an E-commerce Evaluation criteria system. Fuzzy Analytic Hierarchy Process is a new multi-criteria evaluation method evolved from Saaty’s AHP. This paper aimed to find out the key factors that affect success in E-commerce using fuzzy AHP, and give an evaluation method for E-commerce in order to help researches and mana...

challenges to physicians – those with specific business interests as well as those whose sole focus is patient care. Understanding the law and knowing which, if any, of the many Stark exceptions apply to your arrangement is essential. Part I of this series explained the purpose of the Stark statute, how it differs from the anti-kickback statute and how you can determine whether it applies to ...
