The early theoretical studies that presented conceptual definitions for the mapping of Quality of Experience (QoE) through Quality of Service (QoS), in an approach focused on Distributed Databases (DDBs), showed the directions to be threshed in a way to accomplish a hybrid DDBs' QoE-QoS set of evaluation criteria. That evaluation set being classified explicitly as partial, since QoE is a known multidimensional...
This research analyzes the performance of a distributed cloud broker in a live traffic scenario, utilizing a government owned private federated cloud. The paper explores the use case when a cloud broker assists the provisioning of services to geographically distributed data centers which have volunteered to federate and expose their utilization metrics to each other through the cloud broker. The experimental...
This study presents reliability analysis of virtual machine instances in public cloud environments in the face of dynamic pricing. Different from traditional fixed pricing, dynamic pricing allows price to dynamically fluctuate over arbitrary period of time according to external factors such as supply and demand, excess capacity, etc. This pricing option introduces a new type of fault: virtual machine...
Web applications and server environments hosting them rely on configuration settings that influence their security, usability, and performance. Misconfiguration results in severe security vulnerabilities. Recent trends show that misconfiguration is among the top critical risks in web applications. While effective at uncovering numerous classes of vulnerabilities, generic web application vulnerability...
The Service Level Agreement(SLA) of current cloud computing often focuses on performance while seldom emphasizes security; additionally, customers have to select the most suitable one among several Cloud Service Providers (CSPs). Therefore, a cloud-oriented meta-synthesis selection method is proposed as well as a cloud computing security SLA indicators system by using Delphi and Goal-Question-Metric...
Evaluation of ambient assisted living (AAL) systems is particularly challenging due to the complexity of such systems and the variety of solutions adopted and services offered. Yet analyzing and comparing AAL solutions is paramount for assessing research results in this area. Evaluating AAL Systems through Competitive Benchmarking (EvAAL) is a recently established international competition that aims...
Daylighting has an important role in sustainable architecture as it affects the energy consumption in a building. Especially for an office building, daylight helps not only to reduce the load on artificial lighting but also to promote work efficiency through promoting good human health, wellbeing and user comfort. The objective of this research is to invent an innovative façade design strategy that...
