data envelopment analysis (dea) is a branch of management, concerned with evaluating the performances of homogeneous decision making units (dmus). the performances of dmus are affected by the amount of sources that dmus used. usually increases in inputs cause increases in outputs. however, there are situations where increase in one or more inputs generate a reduction in one or more outputs. in ...

The presence of people in urban spaces and related components is one of the most important issues in the field of behavioral sciences in urban studies. The mechanism of static presence in urban spaces is influenced by factors that generally determine the quality of social life in these spaces. The present study examines the way people are present in urban spaces in relation to each other, and i...

Drivers in urban neighborhoods who cruise streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The solution to this problem is to reduce the total traffic volume including cruising traffic by implementing a congestion pricing scheme: the imposition of a usage fee on a limited-capacity resource during times of high demand. We review the his...

Locational Marginal Pricing (LMP) is a method for energy pricing in deregulated power systems. Loss and congestion cause different prices for energy at load or generation buses. In this pricing method there is a different between payments of customers and revenue of generators which is called Merchandizing Surplus (MS). Independent System Operator (ISO) receives MS and generally renders it to T...

In the recent years, heterogeneous network (HetNet) is used to improve the spectral efficiency and network capacity of Long Term Evolution-Advanced (LTE-A). Although, it has huge traffic congestion due to numerous numbers of mobile users and data terminals, leads to problems of cooperation between Macro-cell and Pico-cells. One of the major interference sources in LTE-A is Common Reference Sign...

Quantization effects are inevitable in networked control systems (NCSs). These quantization effects can be reduced by increasing the number of quantization levels. However, increasing the number of quantization levels may lead to network congestion, (i.e., the network needs to transfer more information than its capacity). In this paper, we investigate the problem of designing a robust H∞output ...
