Reactive routing protocols for mobile ad-hoc networks usually discover routes by disseminating control packets across the entire network; this technique is known as brute-force flooding. This paper presents NARD, which stands for neighbor-assisted route discovery protocol for mobile ad-hoc networks. In NARD, a source node floods a limited portion of the network searching not only for the destin...

The non-revisiting path conjecture for polytopes, which is equivalent to the Hirsch conjecture, is open. However, for polyhedral maps on surfaces, we have recently proved the conjecture false for all orientable surfaces of genus g/> 2 and all nonorientable surfaces of nonorientable genus h/>4. In this paper, a unified, elementary proof of the non-revisiting path conjecture is given for the sphe...

Motivations are critical factors in understanding tourists’ behaviors relation to destination choice; they relate needs, goals, and preferences. Extensive research on this topic has been documented the literature. However, there few empirical studies ecotourist cities mountainous regions that facing an increasing number of challenges due cost infrastructure development. Attention motivational i...

The present study aims to widen the existing literature by discovering potential determining factors at selected ecotourism destinations, primarily involving Bako, Niah, Kubah, Gunung Gading and Mulu National Parks. A closed questionnaire was answered 188 respondents. Preliminary analyses were performed partial least square structural equation modeling employed as analytical measure, thus signi...

BACKGROUND To validate the use of the Charlson Comorbidity Index (CCI) for predicting admission of patients revisiting the Emergency Department (ED) within 72 hours. METHODS Non-trauma patients aged above 17 years old who revisited an urban ED within 72 hours during January of 2004 were included in this retrospective observational study. Demographic data, diagnosis, CCI, in-hospital mortality...

Current theory in tourism marketing lacks understanding of how businesses signal trust to consumers make destination-based choices. The present research investigates the role E-WOM, destination image, familiarity, and (as mediator) choice from signaling perspective. suggests that there is asymmetric information between receiver sender which can be resolved by communicating various positive sign...

OBJECTIVE To carry out a spatial analysis of the occurrence of acts of violence (specifically robberies) in public transportation, identifying the regions of greater incidence, using geostatistics, and possible causes with the aid of a multicriteria analysis in the Geographic Information System. METHODS The unit of analysis is the traffic analysis zone of the survey named Origem-Destino, carr...
