There is an increasing realization across the globe that the resources available in society for the provision of medical care are fi nite. As such, in addition to establishing the effi cacy and effectiveness of spinal procedures, it is becoming increasingly important to also describe their economic impact. In general, the most compelling analyses are those which compare the costs and effi cacy ...

Interpretation of the massive amount of data (i.e,. microstructure images comprising millions of voxels) produced by emerging three-dimensional (3-D) characterization methods of polycrystalline materials, require very effi cient models. Such models should be able to use direct input from those images to predict mechanical response. In this work we present a formulation based on fast Fourier tra...

Rebound eff ects measure the behaviorally induced off set in the reduction of energy consumption following effi ciency improvements. Using panel estimation methods and household travel diary data collected in Germany between 1997 and 2009, this study identifi es the rebound eff ect in private transport by allowing for the possibility that fuel price elasticities – from which rebound eff ects ca...

Suppose that a group of agents have demands for some good. Each one of them owns a technology allowing to produce the good, with these technologies varying in their effectiveness. We consider technologies exhibiting either increasing return to scale (IRS) or decreasing returns to scale (DRS). In each case, we solve the issue of the effi cient allocation of the production between the agents. In ...

The feasibility of total petroleum hydrocarbon-contaminated (TPH) soil remediation was studied using persulfate oxidation. Factors tested included type of activator, persulfate concentration, number of persulfate applications, and reaction time. Probe chemicals were used to study effi ciency of the persulfate oxidation mechanism. The best activation method used Fe2+, which achieved 40.8% TPH de...

Stochastic dominance (SD) has been identified as an important method for effi cient diversification. However, the SD rule is too rigid in that it remains silent on some obvious preferences between two distributions for most investors as pointed out by Leshno and Levy (2002). Thus the purpose of this paper is to derive an effi cient frontier according to generalized almost stochastic dominance (...

Properly functioning markets effi ciently allocate resources. Such markets must refl ect certain principles, including consumer options, cost-based pricing, and economic neutrality. Transportation markets oft en violate these principles. This report examines these distortions and their implications for transport planning. Transportation market distortions include various types of underpricing o...
