In many developing countries, public transit plays an important role in daily life. However, few existing methods have considered the influence of public transit in their models. In this work, we present a dual-perspective view of the epidemic spreading process of the individual that involves both contamination in places (such as work places and homes) and public transit (such as buses and trai...

This paper looks at whether bribes for electricity connections affect electricity reliability. Using detailed firmlevel data, we estimate various specifications based upon repeated cross-sections and means-based pseudopanels to show that bribes are closely related to poorer electricity reliability. We find that the propensity to bribe for an electricity connection is associated with an increase...

Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...

A typical strategy for dealing with commodity surpluses is to store them for future sale; though electricity cannot yet be stored on a large scale, this storage strategy will become a natural choice for dealing with electricity surpluses. However, because electricity prices can be negative, there exists another potential strategy: To buy electricity surpluses at negative prices and dispose of t...

Remarkably higher expected shares of variable renewable energy sources for electricity generation (RES-Electricity) than those available today will be a great challenge for the European power system. Bulk electricity storage technologies— that is, pumped hydro energy storage—are considered a key component while facing these future challenges. The conducted analysis is based on the modeling resu...

In this paper we deal with the European electricity market liberalization problem, formulated as a game with electricity producers as players, while the consumers’ electricity demand is exogenous. The producers maximize their profit by choosing how much electricity they will produce individually by means of electricity production available to them. The aim of the research presented in this pape...

Accurate modeling and forecasting monthly electricity consumption are the keys to optimizing energy management and planning. This paper examines the seasonal characteristics of electricity consumption in Hong Kong—a subtropical city with 7 million people. Using the data from January 1970 to December 2014, two novel nonlinear seasonal models for electricity consumption in the residential and com...

By international standards the economy of South Africa is extremely energy intensive with only a few countries having higher intensities. SA’s primary energy use per unit of GDP is amongst the highest in the world The high energy and electricity intensity of the economy partly reflects SA’s resource endowments (in particular the abundance of coal) but is also a function of the historical under-...

Pycnocycla spinosa Decne. ex Boiss. var. spinosa (Fam. Umbelliferae) is an essential oil-containing wild plant growing in central part of Iran. Hydroalcoholic extract of Pycnocycla spinosa has antispasmodic and antidiarrheal activity. The aim of this study was to further investigate antidiarrheal and small intestinal transit effect of P. spinosa extract for a comparison with loperamide and dicy...

• Produces optimized non-uniform set of speed levels • Enables dynamic, traffic-responsive grouping • Reduces transit times and attack rates compared to the existing group transit scheme with fixed schedules and uniform speed levels Randomized Transit Routing • Randomizes vessel transit routes to make them maximally unpredictable and reduces attack rates • Utilizes the transit game model (twopl...
