Abstract Urban building energy modelling has an essential role in the estimation of demand at urban or neighbourhood scales. However, current methods have limitations reproducing realistic gross usage. Although it is theoretically possible to simulate all components heating system detail, such extensive approach significantly increases computational effort, prohibiting a large scale probabilist...

Compression Ratio (CR) and Logical Operation Time (LOT) are two major measures of the efficiency of bitmap indexing. Previous works by [5, 9, 10, 11] compare the performance of bitmap compression schemes conducted separately on logical operation time and compression ratio. This paper will describe these works and recommend for consideration a new matrix – overall efficiency indicator. The overa...

In the current economic climate, business schools face crucial decisions. As resources become scarcer, schools must either streamline operations or limit them. An efficiency analysis of U.S. business schools is presented that computes, for each business school, an overall efficiency score and provides separate factor efficiency scores, indicating the extent to which the school can reduce each r...

Two-dimensional (2-D) wireless power transfer (WPT) systems can be controlled by either the directional method or rotational method. The refers to use of omnidirectional transmitter generating flux regardless load positions, while magnetic directly toward power-consuming directions. This article compares overall efficiency two methods for 2-D WPT systems. Theoretical analysis reveals that more ...

Background and Objectives: Emergency departments often encounter several risk and health issues which significantly impact on overall healthcare performance. Resilience engineering (RE) enables emergency departments to confront sudden changes and handling health risk issues. Patient trust (PT) is also one of the most effective factors which improve quality of care along with pa...

in this paper, by introducing two virtual decision-making units (dmus) called ideal dmu (idmu) and anti-ideal dmu (admu) with fuzzy inputs-outputs, the efficiency evaluation of dmus are done by fuzzy data envelopment analysis (fdea). therefore, we evaluate dmus from the perspective of the best and worst possible relative efficiency. for each dmu two efficiencies are calculated while inputs and ...

The measure proposed in this paper is a new nonparametric data envelopment analysis (DEA) scheme, the hybrid measure, for determining efficiency in the presence of radial and nonradial inputs or outputs. Further extension of the scheme occurred to address nonseparable desirable and undesirable outputs. Applying the model to measure the overall efficiency of U.S. electric utilities in the presen...

A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid. In real-life situations, all mixture blends comprise of at least a minimum proportion of each component. Here, we introduce simplex-centroid designs which contain complete blend...

  In this article, Non radial method of dynamic DEA with the parallel network structure is presented and is used for calculation of relative efficiency measures when inputs and outputs do not change equally. In this model, DMU divisions under evaluation have been put together in parallel. But its dynamic structure is assumed in series. Since in real applications there are undesirable inputs an...
