Modeling, Predicting and Reducing Energy Consumption in Resource Restricted Computers

Green computing has received significant attention in the past few years. Although some research has addressed cooling and energy usage reduction in large data-centers [1], they do not control how resources are used by applications. Scientific workflows are a useful representation for managing the execution of large-scale computations on high performance computing (HPC) and high throughput comp...

Background and Purpose: The emergency severity index (ESI) triage system has been recommended by the Ministry of Health to classify patients at emergency departments. This study aimed to assess the validity of ESI system (version 4) in the emergency department of a teaching hospital. Outcome measures were hospitalization, emergency department (ED) length of stay, resource consumption, in-hospit...

The triage system in the emergency department classifies patients according to priority levels of care. Neonates are a vulnerable population and require rapid assessment. OBJECTIVE To correlate the priority levels in newborns seen in the paediatric emergency department with admissions, resource consumption, and service times. PATIENTS AND METHOD Observational study, using the Andorran triag...

With phenomenal growth in wireless multimedia image communication, the issues need to handle are resource consumption and the quality of the image being transmitted in wireless channels. The resource consumptions indicated in most literatures are bandwidth and energy consumption. The strict constrains of wireless sensor networks (WSN) on individual sensor node’s resource brings great challenges...

The conditions that can lead to the exploitative depletion of a shared resource, i.e., the tragedy of the commons, can be reformulated as a game of prisoner's dilemma: while preserving the common resource is in the best interest of the group, over-consumption is in the interest of each particular individual at any given point in time. One way to try and prevent the tragedy of the commons is thr...

Metrics on resource productivity currently used by governments suggest that some developed countries have increased the use of natural resources at a slower rate than economic growth (relative decoupling) or have even managed to use fewer resources over time (absolute decoupling). Using the material footprint (MF), a consumption-based indicator of resource use, we find the contrary: Achievement...

We propose a new architecture for performing Elliptic Curve Scalar Multiplication (ECSM) on elliptic curves over GF (2). This architecture maximizes the parallelism that the projective version of the Montgomery ECSM algorithm can achieve. It completes one ECSM operation in about 2(m−1)(dm/De+4)+m cycles, and is at least three times the speed of the best known result currently available. When im...

Shortage of water resources and increasing demand to consumption of this scarce resource, leads to somenoticeable limitations. On the other hand, population growth and consequently, increasing demand for water in aridand semi arid regions , needs production in exchange of little amount of water consumption. To approach thisobjective, an experiment in the complete randomized blocks carried out i...
