This paper proposes an architecture to achieve cooperative behaviour among a set of robotic devices. The architecture, with a pure reactive nature privileges the use of local decision mechanisms instead of centralized ones. The performance assessment for the execution of a class of tasks common in the operation of mobile manipulators is made via a particular mission composed by a number of tasks.

OBJECTIVE The aim of this study is to investigate the effects of cooperative training on the pretreatment assessment of the feasibility to perform Ultrasonography (US) guided percutaneous radiofrequency ablation for patients afflicted with hepatocellular carcinoma. MATERIALS AND METHODS In our prospective study, 146 patients with 200 hepatocellular carcinomas were referred for radiofrequency ...

ABSRACT: The cost incurred on installation for broadband data for consumer has made the power line communication the technology to be considered for the provision. As appropriate as this medium is, the challenges inherent in it makes high-speed transmission unreliable, as signal propagated through it suffers attenuation, experiences multipath and bewitchment of noise. This causes depreciation o...

In the development of past infrastructures, cooperative and amateur action has been a vehicle for diffusion, experimentation, innovation, popularization, and the provision of new features or services. 802.11 (“Wi-Fi”) cooperatives are now proliferating. This user study considers three cases of cooperative action in the discovery, development, and provision of 802.11 (Wi-Fi) networks: (1) mappin...

Legislation grows in number and complexity, and so does the need to get informed about them, and to be able to infer the consequences of rules and requirements for particular situations. Access to legal sources has thus far been handled in the same way as information retrieval in general by using database technology. This misses out what is the crucial issue in legal information serving (LIS): ...

We translate a theory into the practice of intelligence assessments. Following Karl Weick’s (1993) retrospective approach, translation relies on previously published evaluations assessment practices. Intelligence assessments are used in organizations to inform leaders threats and opportunities. The we apply describes how an analyst learns through dialogue during conducting assessment, it consis...

The performance of women agribusiness cooperatives in Oyo State, Nigeria was assessed in this study. The study employed a multi-stage sampling technique to select 6 women cooperative groups (aggregating to 175 individuals); 36 individual women; and 4 institutions across 6 LGAs in two agricultural zones of the State. Findings show that majority (55.6%) of the respondents belong to processing org...

OBJECTIVE To systematically review the main methods for nutritional risk assessment used in critically ill cancer patients and present the methods that better assess risks and predict relevant clinical outcomes in this group of patients, as well as to discuss the pros and cons of these methods according to the current literature. METHODS The study consisted of a systematic review based on ana...

Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...

Cooperative and gradual covering are two new methods for developing covering location models. In this paper, a cooperative maximal covering location–allocation model is developed (CMCLAP). In addition, both cooperative and gradual covering concepts are applied to the maximal covering location simultaneously (CGMCLP). Then, we develop an integrated form of a cooperative gradual maximal covering ...
