This thesis addresses the problem of how to share efficiently information within a robotic system comprised of several mobile robots, which are programmed to exhibit cooperative behavior in the context of building volumetric maps of unknown environments. More specifically, it addresses the following issues: representing a probabilistic map and improving it through efficient exploration, based o...

-This paper describes the development and testing of a new evolutionary robotics research test bed. The test bed consists of a colony of small computationally powerful mobile robots that use evolved neural network controllers and vision based sensors to generate team gameplaying behaviors. The vision based sensors function by converting video images into range and object color data. Large evolv...

BACKGROUND Patient follow-up is a routine component of clinical practice and valuable for evaluating the effectiveness of interventions, but because of the broad dispersion of health facilities and lack of standardised medical reporting in Malawi, collecting patient outcome data can be challenging. Increasing accessibility and affordability of mobile technology in resource-poor settings may fac...

Azzurra Robot Team (ART) is the result of a joint effort of six Italian research groups from Univ. of Genova, Politecnico Milano, Univ. of Padova, Univ. of Palermo, Univ. of Parma, Univ. Roma ”La Sapienza”, and Consorzio Padova Ricerche which has provided resources and a set up of the soccer field in its Center in Padova. We have developed the team within the framework of the RoboCup Italia Pro...

the production, distribution, and consumption of information are the most important development indices of any nation. plenty of opportunities were created by e-learning which have overall paved the grounds for and enriched the presentation of learning materials through advanced audiovisual educational facilities. such learning environments are by and large flexible and provide more appropriate...

this study aimed at examining the major mobile wireless technologies, that is,mobile phones and the possibilities associated with them, currently in use in theeducational domains, with an emphasis on language teaching and learning practices.accordingly, some of the most typical studies using different functions of mobilephones such as e-mail, multimedia capabilities, wireless application protoc...

FOREWORD The project required collaboration among a number of entities on three continents: the Financial Sector Team within the Policy Division of DFID UK financed and supported the main project (Justin Highstead); and two country financial sector programmes, FSD in Kenya (David Ferrand) and FinMark Trust in South Africa (Jeremy Leach), financed and facilitated the country-level information ga...

Learning based on e-learning, being ubiquitous, allows easy access anywhere [3,7]; in addition, the design of games or simulations, included in web platforms, enables the teaching to be more dynamic [8,9]. The nursing professionals are the most important [10], health workers that use a mobile phone for work. They use their personal mobile phones in order to acquire information and to be in cont...

Collaboration supported by mobile devices has brought advantages for users and also challenges for software developers and mobile computing devices manufacturers. Every kind of device used to support mobile collaboration has strengths and weaknesses depending on the work context where it is used. The idea is to use a specific device when advantages are most relevant and disadvantages do not aff...

This paper builds on the experiences gained from the extensive work carried out during the MOST project [MOST,95]. This project investigated the use of mobile technologies to support multimedia collaboration between highly mobile field engineers in the safety critical domain of the U.K. power distribution industry. The MOST team developed a prototype distributed groupware application which was ...
