Total Maximum Daily Load (TMDL) implementation generates benefits and costs from water quality improvements, which are rarely quantified. This analysis examines a TMDL written to address bacteria and aquatic-life-use impairments on Abrams and Opequon Creeks in Virginia. Benefits were estimated using a contingent valuation survey of local residents. Costs were based on the number and type of bes...

The aim of this research is to find out whether the firefighter manpower is adequate to the requirements in the field under the most severe conditions. It also attempts to test whether firefighters' working ability corresponds to their age. To that purpose 220 Croatian firefighters from the Littoral Mountainous county, 99 professional firefighters from the city of Rijeka, 45 professional firefi...

In this paper, a general formula for nding the Maximum Allowable Dynamic Load (MADL) of geometrically nonlinear exible link manipulators is presented. The dynamic model for links in most mechanisms is often based on the small de ection theory but for applications like lightweight links, high-precision elements or high speed it is necessary to capture the de ection caused by nonlinear terms. Fir...

The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one gyratory crusher which feeds one SAG mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a tromm...

Online algorithms are usually analyzed using the notion of competitive ratio which compares the solution obtained by the algorithm to that obtained by an online adversary for the worst possible input sequence. Often this measure turns out to be too pessimistic, and one popular approach especially for scheduling problems has been that of “resource augmentation” which was first proposed by Kalyan...

Cylindrical Frictional Damper (CFD) is a new revolutionary frictional based mechanical damper. Unlike the other types of frictional dampers, CFDs do not utilize bolts to produce friction between contact surfaces. These dampers consist of two main parts, the inner shaft and the external cylinder. These two parts are assembled such that one is shrink-fitted inside the other. In this investigation...

Demand-side load management (DSM) requires greater role-play by end-users. To lower the investment for this concept, non-intrusive (NILM) was introduced as solution. However, most of mathematical techniques used in NILM are complex. This may hinder users from actively take part energy effort. paper explores possibilities applying change point detection with help differentiation and application ...
