The growing popularity of virtual currencies such as Bitcoin, an Internet innovation with a function similar to "fiat" money or government money, due to the high velocity and efficiency in transactions (especially overseas payments) as well as the elimination of the additional operating costs incurred by intermediaries attract the policymakers and global decision-making centers attention. The p...

Socioeconomic drought broadly refers to conditions whereby the water supply cannot satisfy the demand. Most previous studies describe droughts based on large-scale meteorological/hydrologic conditions, ignoring the demand and local resilience to cope with climate variability. Reservoirs provide resilience against climatic extremes and play a key role in water supply and demand management. Here ...
Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
We consider a repeated newsvendor problem where the decision-maker (DM) does not have access to the underlying distribution of discrete demand. We analyze three informational settings: i.) the DM observes realized demand in each period; ii.) the DM only observes realized sales ; and iii.) the DM observes realized sales but also a lost sales indicator that records whether demand was censored or ...
This article develops indicators to monitor energy efficiency developments in the food and tobacco industry based on physical production data at the firm level provided by the statistics office of the Netherlands in a confidential basis. We measure energy efficiency by using an energy efficiency indicator which is the aggregate specific energy consumption. Our results show that the food and tob...
Considering water resource scarcity and uncertainty in climate and demand futures, decision-makers require techniques for sustainability analysis in resource management. Through unclear definitions of “sustainability”, however, traditional indices for resource evaluation propose options of limited flexibility by adopting static climate and demand scenarios, limiting analysis variables to a part...
OBJECTIVE To analyze the requesting patterns for a range of laboratory tests ordered in 2009 from eight laboratories providing services to eight health areas, using appropriate indicators. DESIGN Indicators measured every test request per 1,000 inhabitants, and indicators that measured the number of tests per related test requested by general practitioners were calculated. The savings generat...
