Measuring the quality of metadata is only possible by assessing the quality of the underlying schema and the metadata instance. We propose some factors that are measurable automatically for metadata according to the CMD framework, taking into account the variability of schemas that can be defined in this framework. The factors include among others the number of elements, the (re-)use of reusabl...

In order to search for economically and environmentally optimized fusion reactors, physics properties, engineering designs and the cost of electricity (COE) are evaluated by the PEC (Physics-Engineering-Cost) system code for several magnetic confinement fusion reactors including tokamak (TR), helical (HR) and spherical tokamak (ST) reactors. The life-cycle CO2 emission amounts are also evaluate...

This paper argues that many new production techniques have been developed by a process called 'collective invention'. When firms collectively invent, they make available to their competitors the results of new plant designs so that their competitors can incorporate extensions of tliose designs into new facilities they build. The paper analyses the implications of this behavior for the rate and ...

A novel method is presented for the design of heat exchanger networks. The method is the first to combine sufficient simplicity to be used by hand with near certainty to identify “best” designs, even for large problems. “Best” designs feature the highest degree of energy recovery possible with a given number of capital items. Moreover, they feature network patterns required for good controllabi...

High-confidence embedded real-time designs stretch the demands placed on design and development tools. We will demonstrate the design and testing of an embedded control system built using the ESMoL modeling language and supporting tools. ESMoL adds distributed deployment concepts to Simulink designs, and integrates scheduling analysis as well as platformspecific simulation. The testing system i...

Yard-scale landscape designs can influence environmental quality through effects on habitat, stormwater runoff, and water uality. Native plant gardens may have ecological benefits, and previous research has shown that yards using these plants an be designed in ways that people find attractive. This study examines whether people are willing to pay more for more cologically benign designs than fo...

Plants can have positive effects on each other in numerous ways, including protection from harsh environmental conditions. This phenomenon, known as facilitation, occurs in water-stressed environments when shade from larger shrubs protects smaller annuals from harsh sun, enabling them to exist on scarce water. The topic of this paper is a model of this phenomenon that allows search algorithms t...

This presentation provides an overview of the impact of food components and dietary factors on oral health. The protective properties of various foods, plant extracts and plant-based polyphenolic compounds on dental caries and periodontal disease are discussed. Laboratory, human, and epidemiological studies demonstrating the multiple mechanistic actions in supporting their contribution to oral ...
