This paper focuses on estimating maximum resource loads in ResourceConstrained Project Scheduling Problem (RCPSP). We examine a variant of vector sum problem with fractions: considering preemptions allowed, determine what part of each of n jobs should be accomplished in order to minimize sum of squares of non-consumed amounts of resources, taking into account the resource constraints along with...

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...

This paper aims to define the best building orientation for parts manufactured with the laminated object manufacturing technique (LOM), to enhance their flexural performance. Previous research has shown that parts manufactured with LOM have the ability to withstand higher deflections than components created through other layer manufacturing techniques, but, so far, no relation between the build...

Causal attribution has been one of the most influential frameworks in the literature of achievement motivation, but previous studies considered achievement attribution as relatively deliberate and effortful processes. In the current study, we tested the hypothesis that people automatically attribute their achievement failure to their ability, but reduce the ability attribution in a controlled m...
