In Brazil, Energy Market players dedicate many efforts in valuation and optimal allocation of capital decision to implement projects, due the large candidate projects number in their investment portfolios. The strategic decisions of those players should choose the projects subset that will be implemented, because usually, they don ́t have the financial resources to implement all then. Many are t...

Projects in the mining industry are undertaken with the objective of maximizing economic value, which is near-universally measured by the Net Present Value (NPV), considering all capital expenditure and operating cash flow. This industry is usually considered high risk because of historically volatile commodity prices (directly impacting revenues) and the fact that very large capital expenditur...

PURPOSE We aimed to evaluate the utility of shear wave elastography (SWE) for assessing the placenta in preeclampsia disease. METHODS A total of 50 pregnant women in the second or third trimester (23 preeclampsia patients and 27 healthy control subjects) were enrolled in the study. Obstetrical grayscale and Doppler ultrasonography, SWE findings of placenta, and prenatal/postnatal clinical dat...

[Context] Lean and agile software development processes encourage delivering software in small increments so as to generate early business value, be able to adapt to changes, and reduce risks. Deciding what to build in each iteration is an important requirements engineering activity. The Incremental Funding Method (IFM) partly supports such decisions by identifying sequences of features deliver...

The notion of Net Present Value (NPV) is thought to formally translate the notion of economic profit, where the discount rate is the cost of capital. The latter is the expected rate of return of an equivalent-risk alternative that the investor might undertake and is often found by making recourse to the Capital Asset Pricing Model. This paper shows that the notions of disequilibrium NPV and eco...

Abstract Water Alternating Gas (WAG) is a cyclical process that involves alternating water and gas injections with the primary goal to improve sweep efficiency by maintaining initial high pressure, slowing breakthrough, lowering oil viscosity. The objective of this work apply optimize WAG strategy on carbonate field light oil, compare it initially planned water-flooding strategy, investigate ca...

This paper presents a multi-mode resource-constrained project scheduling problem (MRCPSP) with maximizing the net present value (NPV) form the project contractor’s point of view. Positive and negative cash flows are considered in this model. Furthermore, to make the model close to the real situations, four different models for positive cash flows are considered. Two meta-heuristics, called simu...

The Net Present Value maximizing model has a respectable ancestry and is considered by most scholars a theoretically sound decision model. In real-life applications, decision makers use the NPV rule, but apply a subjectively determined hurdle rate, as opposed to the “correct” opportunity cost of capital. According to a heuristics-and-biases-program approach, this implies that the hurdle-rate ru...

The purpose of this paper is to examine the convergent and nomological validity of a GPS-based measure of daily activity, operationalized as Number of Places Visited (NPV). Relations among the GPS-based measure and two self-report measures of NPV, as well as relations among NPV and two factors made up of self-reported individual differences were examined. The first factor was composed of variab...
