Typical pricing models for IaaS cloud providers are slotted, using hour and month as time units for metering and charging resource usage. Such models lead to financial loss as applications may release resources much earlier than the end of the last allocated time slot, leaving the cost paid for the rest of the time unit wasted. This problem can be minimized for multi-tenant environments by mana...

Based on the GSM radio architecture, general packet radio service (GPRS) provides users data connections with variable data rates and high bandwidth efficiency. In GPRS service, allocation of physical channels is flexible, i.e., multiple channels can be allocated to a user. In this paper, we propose four algorithms for the GPRS radio resource allocation: fixed resource allocation (FRA), dynamic...

Resource management has been recognised as an important topic for the execution of business processes since long time ago. Yet, most exiting works on resource allocation have not paid enough attentions to process characteristics, such as structural and task dependencies. Furthermore, no effort has been made on optimising resource allocation by improving business processes. To address this issue...

The objective of the proposed project work is Downlink resource allocation for OFDMA-based next generation wireless networks subject to inter-cell interference (ICI). The main aim of the project is balanced performance improvement between cell edge and cell centre users. The resource allocation scheme consists of radio resource and power allocation, which are implemented separately. To achieve ...

a r t i c l e i n f o JEL classification: C1 C6 G1 Keywords: Energy stocks C-vines D-vines Dependence structure Risk measures Portfolio optimization This article models the dependence risk and resource allocation characteristics of two 20-stock coal–uranium and oil–gas sector portfolios from the Australian market in the context of the global financial crisis of 2008–2009. The modeling framework...

Many biological, geophysical, and technological systems involve the transport of a resource over a network. In this paper, we present an efficient method for calculating the exact quantity of the resource in each part of an arbitrary network, where the resource is lost or delivered out of the network at a given rate, while being subject to advection and diffusion. The key conceptual step is to ...

Health is increasingly seen as relevant to foreign policy; nevertheless, it remains subordinate to other interests. In particular, the interests of security and economics are often presented as more critical than health. This is due to a failure to sufficiently recognize the legal obligations that states have undertaken to ensure the human right to health. This article argues that health should...

Modern-day health systems have suffered from a mismatch between the seemingly limitless demand for health services and the finite physical and financial resources available to supply such services almost since their inception. 1 However, the affordability of such systems has undoubtedly risen up the policy agenda recently to become a significant contemporary problem worldwide, as the impact of ...

Emergency resource is important for people evacuation and property rescue when accident occurs. The relief efforts could be promoted by a reasonable emergency resource allocation schedule in advance. As the marine environment is complicated and changeful, the place, type, severity of maritime accident is uncertain and stochastic, bringing about dynamic demand of emergency resource. Considering ...

The study described here tested a model of how characteristics of the feedback environment influence the allocation of resources (time and effort) among competing tasks. Results demonstrated that performers invest more resources on tasks for which higher quality (more timely and more specific) feedback is available; this effect was partially mediated by task salience and task expectancies. Feed...
