Visual effects play an important role in the film and game industry, In both, the observer immerses into a virtual world which comes already amazingly close to the real world. One approach is to collect parts of the real world and reassamble them at will. When following this approach for complicated surface materials, the material must be recorded for many different viewing and illumination con...

Transportation infrastructures have recently gained increasing attention in the context of homeland security. Being both a main target for attacks as well as a method for carrying out such attacks, much effort is being allocated these days towards increasing our understanding regarding transportation networks [14]. Specifically, measuring and predicting human mobility patterns along the links o...

The Analytical Hierarchy Process (AHP) was used to characterize the bridge material selection decisions of highway officials across the United States. Understanding product choices by utilizing the AHP allowed us to develop strategies for increasing the use of timber in bridge construction. State Department of Transportation engineers, private consulting engineers, and local highway officials w...

This paper considers the simultaneous scheduling of material handling transporters (such as Automatic Guided Vehicles or AGVs) and manufacturing equipment (such as machines and workcenters) in the production of complex assembled products. Given the shipping schedule for the end-items, the objective of the integrated problem is to minimize the cumulative lead time of the overall production sched...

OBJECTIVE This study has two aims: 1) to evaluate the apical transportation of the Wizard CD Plus and ProTaper Universal after preparation of simulated root canals; 2) to compare, with Adobe Photoshop, the ability of a new software (Regeemy) in superposing and subtracting images. MATERIAL AND METHODS Twenty five simulated root canals in acrylic-resin blocks (with 20º curvature) underwent cone...

The spatial distribution and deposition of lead and zinc emitted from the Trail smelter, British Columbia, Canada, was studied by strategically locating moss bags in the area surrounding the smelter and monitoring the deposition of elements every three months. A combined diffusion/distribution model was applied to estimate the relative contribution of stack-emitted material and material emitted...

The aim of this research is to examine the market potential for wood plastic composite (WPC) products in the highway construction sector in place of nonrenewable materials (e.g. virgin plastic and steel) and preservative-based products (treated wood). State-level transportation officials indicate that the majority of highway construction purchases are conducted by highway construction contracto...

We describe a model for deploying radiation detectors on a transportation network consisting of two adversaries: a nuclear-material smuggler and an interdictor. The interdictor first installs the detectors. These installations are transparent to the smuggler, and are made under an uncertain threat scenario, which specifies the smuggler’s origin and destination, the nature of the material being ...

Separation by implanted oxygen (SIMOX) material has proven to provide an extended temperature range (up to 500°C) of operation for partially depleted silicon-on-insulator (SOI) test structures and product circuits in both transportation and communication applications. Such high temperature use is possible due to the built-in dielectric isolation which eliminates the isolation junction and its a...

The Analytical Hierarchy Process was used to characterize the bridge material selection decisions of highway engineers and local highway officials across the United States. State Department of Transportation engineers, private consulting engineers, and local highway officials were personally interviewed in Mississippi, Virginia, Washington, and Wisconsin to identify how various factors determin...
