The abandonment of land, the high energy load generated and accumulated by vegetation covers, climate change and interface scenarios in Mediterranean forest ecosystems are demanding serious attention to forest fire conditions. This is particularly true when dealing with the budget requirements for undertaking protection programs related to the state of current and future forest landscapes. Base...

In this short paper, we briefly describe some recent progress on statistical decision making for budget allocation in crowdsourcing. We address the budget allocation problem for two important labeling tasks in crowdsourcing: the categorization labeling task and pairwise ranking aggregation. We also show the connections between our work and the “proactive learning” framework proposed by Jaime Ca...

This paper investigates energy efficient power allocation scheme for OFDM-based cognitive opportunistic relaying links (CORL), where secondary users (SUs) may incorrectly sense the unlicensed spectrum and hence transmit data in collision. We aim to maximize the energy efficiency (EE) by optimal and low complexity power allocation design. At first, an energy efficient power allocation optimizati...

Recently the concept of facility efficiency, which defined by data envelopment analysis (DEA), introduced as a location modeling objective, that provides facilities location’s effect on their performance in serving demands. By combining the DEA models with the location problem, two types of “efficiencies” are optimized: spatial efficiency which measured by finding the least cost location and al...

In the search for greater efficiency and cost-containment, many health systems have introduced the practice of medical care providers operating under a fixed budget, often referred to as the capitation or fundholding contract. Although the capitation contract seems equitable at first glance, the sequential decision-making practice of providers-shaped by their rate of present-preference and thei...

background: nowadays, restriction on access and optimum use of resources is the main challenge of development in all organizations. therefore, the aim of this study was to determine the technical efficiency and its factors, influencing hospitals of tehran. methods: this research was a descriptive-analytical and retrospective study conducted in 2014-2015. fifty two hospitals with public, private...

This article describes the results of applying a rigorous computational model to the problem of the optimal defensive resource allocation among potential terrorist targets. In particular, our study explores how the optimal budget allocation depends on the cost effectiveness of security investments, the defender's valuations of the various targets, and the extent of the defender's uncertainty ab...

This paper presents an investigation on the performance of the Non-Orthogonal Multiple Access (NOMA) in the power domain scheme. A Power Allocation (PA) method is proposed from NOMA throughput expression analysis. This method aims to provide fair opportunities for users to improve their performance. Thus, NOMA users can achieve rates higher than, or equal to, the rates obtained with the convent...

In a classical facility location problem we consider a graph G with fixed weights on the edges of G. The goal is then to find an optimal positioning for a set of facilities on the graph with respect to some objective function. We introduce a new framework for facility location problems, where the weights on the graph edges are not fixed, but rather should be assigned. The goal is to find the va...
