Cloud computing now a day's become most popular and reliable computing technique for organizations and individuals. In the cloud environments, data availability and backup replication are critical and complex issues in the an efficient fault tolerance policy is the major. Fault tolerance policy is the strategy in action when a fault occurs in the system. Taking backups is the one of the most us...

The relationship between psychiatry and pharmaceutical companies has come under scrutiny during the past decade. Concerns are growing that financial ties of psychiatrists to the pharmaceutical industry may unduly influence professional judgments involving the primary interests of patients. Such conflicts of interest threaten the public trust in psychiatry. The goal of conflict of interest polic...

BACKGROUND Addressing opioid use disorder has become a priority in Ontario, Canada, because of its high economic, social and health burden. There continues to be stigma and criticism relating to opioid use disorder and treatment options. The result has been unsystematic, partial, reactive policies and programs developed based on divergent points of view. The aim of this manuscript is to describ...

Home wireless networks are difficult to manage and comprehend because of evolving locality, co-locality, connectivity and interaction. We define formal models of home wireless network infrastructure and policies and investigate how they can be used in a network management system designed to provide user-oriented support. We model spatial and temporal behaviour of network interactions and user-i...

Finland has struggled with formulating and implementing policies regarding the national grey wolf (Canis lupus) population. It seems that after major institutional adjustments undertaken to improve wolf protection, the wolf population has, in fact, decreased. This calls for an explanation. My approach to the question of institutional fit builds upon classical institutional economics and pragmat...

Qualitative Decentralized Partially Observable Markov Decision Problems (QDec-POMDPs) constitute a very general class of decision problems. They involve multiple agents, decentralized execution, sequential decision, partial observability, and uncertainty. Typically, joint policies, which prescribe to each agent an action to take depending on its full history of (local) actions and observations,...

The increasingly diverse and dynamic contexts in which current applications are run imposes them to adapt and to become more autonomous. The goal of this thesis is to ease the development of such selfadaptive applications, by considering adaptation as an aspect which should be defined separately from the rest of the application, so as to be integrated and modified dynamically. To this end we pr...

This paper presents a framework for ambient sensing and managing a University building aimed at energy savings and user comfort. The system builds upon previous work, using a Semantic Web Service middleware for unifying the various heterogeneous sensor and actuator networks. Two applications are introduced in the framework, the Manager App and the Rule App. The latter incorporates a hybrid inte...

sepsis is a significant health problem with an estimated 750,000 new cases in the usa annually. it is also the third leading cause of death in developed countries, equaling the number of fatalities from acute myocardial infarction. the high sepsis-related mortalities mean there is an urgent need to improve the diagnosis and management of sepsis patients. the aim of this study was the evaluation...

The monitoring of the quality of service in a multi-domain network supervises the multi-domain service performance. A multi-domain service is a service that crosses several domains which can be managed by different providers. Since each domain can be managed with its own policies and may require confidentialit of its topology and its monitoring processes, we propose that the monitoring architec...
