Video on Demand (VoD) services are characterized by quality of service requirements which depend on: the quality of video and sound transmitted to the client, the respect of time constraints associated to video and audio data and the reliability and accessibility of the service. Much work has been done in order to provide system support aimed at meeting reliability requirements in distributed V...

Resource Acquisition service is a network-based service that acquires sufficient resources to satisfy the application requirement. Set-top-boxes (STB) are good sources of resource providers delivering this type of service collaboratively. Unfortunately, the accessibility of STBs is controlled by end-node users. It leads to uncertainty of the amount of resource available to the service operators...

The article deals with the classification of alternative water resources in terms of potential risks which is the prerequisite for incorporating these water resources to the emergency plans. The classification is based on the quantification of risks resulting from possible damage, disruption or total destruction of water resource caused by natural and anthropogenic hazards, assessment of water ...

VoD services (Video on Demand) are characterized by QoS (quality of service) requirements which depend on: the quality of video and sound transmitted to the client; the respect of time constraints associated to video and audio data; the reliability and the accessibility of the service. Much work has been done in order to provide system support aimed at meeting reliability requirements in distri...

Introduction. This study aims to investigate the selection of information sources and to identify factors associated with the resource selection of undergraduate students for academic search tasks. Also, user perceptions of some factors, such as credibility, usefulness, accessibility and familiarity, were examined to classify resources by their characteristics. Method.A self-generated diary met...

Chromatin accessibility, a crucial component of genome regulation, has primarily been studied in homogeneous and simple systems, such as isolated cell populations or early-development models. Whether chromatin accessibility can be assessed in complex, dynamic systems in vivo with high sensitivity remains largely unexplored. In this study, we use ATAC-seq to identify chromatin accessibility chan...

Abstract International efforts are underway to explore the Moon’s south polar region with robotic and human missions. These missions will address key scientific exploration objectives in a rich possibilities, designed develop sustained lunar presence. To assist trade study among six potential landing sites identified for Artemis astronauts, we examined two of those sites: 007 011. We find that ...
