Rapid prototyping is an important technique for manufacturing. This work refers to the manufacture of hollow patterns made of polymeric materials by rapid prototyping technologies for its use in the preparation of ceramic molds in the investment casting process. This work is focused on the development of a process for manufacturing patterns diff erent from those that currently exist due to its ...

Optimizing international oil exploration projects is one of the main challenges for oil companies in obtaining investment benefits. This paper establishes an integrated evaluation model to maximize investment benefits within the constraints of technical and economic factors, including geological factors, resource quality, geographic conditions, the investment environment, and oil contracts. The...

This paper argues that increased uncertainty, in certain situations, may actually encourage investment. Since earlier studies mostly base their arguments on the assumption of geometric Brownian motion, the study extends the assumption to alternative stochastic processes, such as mixed diffusion-jump, mean-reverting process, and jump amplitude process. A general approach of Monte Carlo simulatio...

Current work on image understanding at the University of Utah is focused principally on using computer vision and related sensing techniques to aid in problems associated with manufacturing. Three projects are now underway: feature-based reverse engineering, benchmarking of IU for man-made objects, and improved integration of inspection with design and manufacturing. In all three projects, the ...

Abstract—This work proposes a fuzzy methodology to support the investment decisions. While choosing among competitive investment projects, the methodology makes ranking of projects using the new aggregation OWA operator – AsPOWA, presented in the environment of possibility uncertainty. For numerical evaluation of the weighting vector associated with the AsPOWA operator the mathematical programm...

This paper re-examines the impact of a firm’s outward foreign direct investemnt on its R&D spending in the home country with propensity score matching method. Employing firm-level panel data on Taiwan’s manufacturing firms covering 1987-2003, this paper first demonstrates that firms with firm-specific and ownership advantages are more likely to undertake overseas inverstment. Controlling for ou...

This paper, considering revenue and cost exposure channels, investigates the effects of exchange rate behaviour on fixed capital investment in Mexican manufacturing sector over 1994-2002. We find that i) currency depreciation has a positive (negative) effect on fixed investment through the export (import) channel; ii) exchange rate volatility impacts mostly export oriented sectors; iii) the sen...
