In Opportunistic Networks, information forwarding is involved when nodes are in range. Absence of network topology knowledge of Opportunistic Network makes information forwarding the most compelling challenge. Endto-end communication in Opportunistic Networks is supported naturally through nodes’ mobility. Disconnected peers are opportunistically connected to each other dynamically as informati...

data on the incidence density (ie, incidence per person-year [PY]) of serious infection, opportunistic infection, and tuberculosis associated with each of the nine biologic therapies currently indicated in rheumatoid arthritis patients are not available. To summarize these data, a systematic review was conducted with searches on PubMed and Embase of literature ranging from January 1998 to Novem...

The opportunistic networks are the variants of Delay Tolerant Networks (DTNs). These networks can be useful for routing in places where there are few base stations and connected routes for long distances. In an opportunistic network, when nodes move away or turn off their power to conserve energy, links may be disrupted or shut down periodically. These events result in intermittent connectivity...

To aware the topology of wireless sensor networks (WSN) with time-variety, and load-balance the resource of communication and energy, an opportunistic routing protocol for WSN based on Opportunistic Routing Entropy and ant colony optimization, called ACO-TDOP, is proposed. At first, based on the second law of thermo-dynamics, we introduce the concept of Opportunistic Routing Entropy which is a ...

The outpatient clinic of special study group on AIDS (POKDISUS) FKUI/RSCM provides health service for most of patients with HIV infection/AIDS in Jakarta. According to information center currently there are approximately 1800 cases and most of them (67%) are intravenous drug users. The study to obtain the profile of opportunistic infection in hospital had been initiated by Aida et al (1999). Th...

Autonomic characteristics can dramatically improve the efficiency of opportunistic communications. The main contribution of autonomic communications to opportunistic architectures is to simplify, automate, protect and enhance the knowledge. This allows empowering and making more effective the information handling and exchanges in the face of a complex, dynamic, uncertain, and unsecured environm...

We present an overview of our group communication system, ChickWeed, for opportunistic networking environments. Opportunistic networking is characterized by sporadic and intermittent connections between wireless devices, such as may arise when embedded devices are carried by humans. ChickWeed is a distributed persistent object store that exploits these connection opportunities through an opport...

With the remarkable prolongation of life achieved among HIV-infected individuals, owing to the use of potent antiretroviral therapy, has come dramatic progress in reducing the incidence of HIV-related opportunistic infections (OIs). There has been considerable focus on antiretroviral therapy and HIV prevention, and most HIV practitioners are highly proficient at managing antiretroviral therapy....

1. INTRODUCTION The fact that reflection and externalization of one's understanding are effective ways of learning has been widely accepted in the field of education. Thus, much effort has been devoted to the various research subjects related to the reflection and externalization [1]. Kashihara and his colleagues, for example, have developed an intelligent self-explanation support system, calle...

Adaptation has long been considered as the Achilles’ heel of case-based reasoning since it requires some domain-specific knowledge that is difficult to acquire. In this paper, two strategies are combined in order to reduce the knowledge engineering cost induced by the adaptation knowledge (AK) acquisition task: AK is learned from the case base by the means of knowledge discovery techniques, and...
