A resource discovery protocol allows networked embedded processors and handheld devices to discover each other’s capabilities. Service Location Protocol (SLP) has been proposed by the IETF for that purpose. The usage of bandwidth, or the amount of traffic, that such a protocol makes is a characteristic that is particularly relevant when devices are mobile and wireless. Protocols that are less c...

This research investigates the usage distribution of instructional resources shared among educators in an online learning community. The usage of a resource is defined by the number of unique educators who use (click on) it. We explored what the usage distribution of these resources looks like and we investigated what underlying mechanisms may have generated the observed distribution. Our resul...

Resource usage models are important asset to analyze and ensure the adequate usage of the system platform resources such as processors and memory elements. In this paper, we present how to construct resource usage models using actual execution information of a large software-intensive system. We have constructed this type of models for an MRI system (a representative large software-intensive sy...

Traditional scheduling algorithms typically aim to minimize the total time cost for processing all tasks. However, in cloud computing environments, computing capability differs for different resources, and so does the cost of resource usage. Therefore, it is vital to take into consideration the usage cost of resources. Along this line, in this paper, we proposed a modified algorithm based on PS...

Cloud computing is a new technological paradigm offering computing infrastructure, software and platforms as a pay-as-you-go subscription based service. Many potential customer’s of cloud services require essential cost assessments to be undertaken before transitioning to the cloud. Current assessment techniques are imprecise and rely on simplified resource requirements that fail to account for...

Future high-quality consumer electronics will contain a number of applications running in a highly dynamic environment, and their execution will need to be efficiently arbitrated by the underlying platform software. The multimedia applications that currently execute in such similar contexts face frequent run-time variations in their resource demands, originated by the greedy nature of the multi...

For some applications, standard resource analyses do not provide the information required. Such analyses estimate the total resource usage of a program (without executing it) as functions on input data sizes. However, some applications require knowing how such total resource usage is distributed over selected parts of a program. We propose a novel, general, and flexible framework for setting up...

A core goal of librarians is to maximize usage of the content to which their libraries subscribe. Webscale or resource discovery systems offer a single search box for library users to access subscribed content. This article examines usage data at the University of Huddersfield to show how resource discovery has helped to increase the usage of publisher content, which has been made available to ...

With careful theoretical development and empirical data examination, this paper investigates several key factors that influence the IT usage in Shanghai firms: technology resource, human resource and environment resource. On the basis of the resource-based view and the process model, the study imports government regulation policies, as well as e-government actions, as environmental resource to ...

The evolutionary mechanisms of energy efficiency have been addressed. One important question is to understand how the optimized usage of energy can be selected in an evolutionary process, especially when the immediate advantage of gathering efficient individuals in an energetic context is not clear. We propose a model of two competing metabolic strategies differing in their resource usage, an e...
