Chapter 7: The Evaluation Of Ontologies, Leo Obrst, Benjamin Ashpole, Werner Ceusters, Inderjeet Mani, Steven Ray, Barry Smith
Chapter 7: The Evaluation Of Ontologies, Leo Obrst, Benjamin Ashpole, Werner Ceusters, Inderjeet Mani, Steven Ray, Barry Smith

Recent years have seen rapid progress in the development of ontologies as semantic models intended to capture and represent aspects of the real world. There is, however, great variation in the quality of ontologies. If ontologies are to become progressively better in the future, more rigorously developed, and more appropriately compared, then a systematic discipline of ontology evaluation must be created to ensure quality of content and methodology. Systematic methods for ontology evaluation will take into account representation of individual ontologies, performance and accuracy on tasks for which the ontology is designed and used, degree of alignment with other ontologies …

Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater

The production of corn-based ethanol in the U.S. is dramatically increasing, and consequently so is the amount of coproduct materials generated from this processing sector. These streams are primarily utilized as livestock feed, which is a route that provides ethanol processors with a substantial revenue source and significantly increases the profitability of the production process. With the construction and operation of many new plants in recent years, these residuals do, however, have much potential for value-added processing and utilization in other sectors as well. Extensive research has been conducted into determining the nutritional properties of distillers dried grains with solubles …

Fractionation Techniques To Concentrate Nutrient Streams In Distillers Grains, Kurt A. Rosentrater, Deepa Subramanian, Padmanaban G. Krishnan

Corn, the most widely produced feed grain in the United States, accounts for more than 90% of the total value and production of feed grains. It is also used for food, industrial materials, and fuel ethanol production. Distillers grains, the major coproduct from ethanol manufacturing, are used as livestock feed. There are, however, other potential options, including value-added food, industrial, chemical, and energy applications. Fractionating distillers grains into concentrated streams of protein, fiber, and fat may be key to facilitating these types of utilization. Previous studies on other products have shown that fractionation is a promising mechanism for extracting valuable …

A major challenge in the work of the National Center for Engineering and Technology Education has been the need to strengthen the research climate across the institutional settings. A number of activities have been directed at that effort: internal funding of small student and faculty research projects; presentations by researchers at Center meetings; providing a research focus for the required core courses in cognitive science, design, problem solving, and creativity; and the evolution of the research framework for the Center. The internal research program has been successful in providing relatively non-threatening experiences with proposal preparation, review, negotiation, and the conduct …
Inspection And Evaluation Of A Bridge Deck Reinforced With Carbon Fiber Reinforced Polymer (Cfrp) Bars, Choo Ching Chiaw, Issam E. Harik
Inspection And Evaluation Of A Bridge Deck Reinforced With Carbon Fiber Reinforced Polymer (Cfrp) Bars, Choo Ching Chiaw, Issam E. Harik
Kentucky Transportation Center Research Report
Cracking in reinforced concrete decks is inevitable. It leads to the corrosion and eventual deterioration of the deck system. The use of non-corrosive reinforcement is one alternative to steel in reinforced concrete construction. This report deals with the field evaluation and performance of a concrete bridge deck reinforced with carbon fiber reinforced polymer (CFRP) bars. The bridge is identified as the Elkin Station Road Bridge on route CR1210 over the Two Mile Creek in Clark County, KY. The CFRP bars were placed in the top and bottom mats of the bridge deck in both the transverse and longitudinal directions. The …
Evaluation Of Work Zone Safety Operations And Issues, Jerry G. Pigman, Kenneth R. Agent, Eric R. Green
Evaluation Of Work Zone Safety Operations And Issues, Jerry G. Pigman, Kenneth R. Agent, Eric R. Green
Kentucky Transportation Center Research Report
Work zone activities are one of the areas with a high potential for compromised safety for workers and road users. Various measures have been taken to increase the level of safety in work zones; including the use of double fines for speeding and the application of speed displays based on radar detection. There has been an effort to improve the effectiveness and safety of flaggers by requiring the use of a stop/slow paddle for most work zone conditions, using lights on the paddle, and increasing visibility by using more reflective clothing. It has been suggested that safety in work zones …

Some Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater

With the rapid growth in the fuel ethanol industry in recent years, considerable research is being devoted to determining distillers dried grains with solubles (DDGS) nutritional properties and to optimizing their inclusion in livestock diets; physical properties of these materials, however, have been largely ignored. Using standard laboratory methods, several physical properties for typical DDGS streams were determined, including moisture content, water activity, thermal properties (conductivity, resistivity, and diffusivity), bulk density, angle of repose, and color. The DDGS samples in this study were golden-brown in color and exhibited physical properties similar to other dry feed ingredients, such as hominy feed, …

Tuyere coke probings have been conducted at Port Kembla over the past decade. This period of operation spans significant change in coking coal preparation as well as the introduction of pulverised coal injection.
Experimental Evaluation Of Adaptive And Variable Structure Control Of Piezoelectric Actuation Systems For Micro/Nano Manipulation, Hwee Choo Liaw, Bijan Shirinzadeh, Denny Oetomo, Gursel Alici

This paper proposes and evaluates an adaptive technique and a variable structure control approach for piezoelectric actuation systems to track specified motion trajectories. The proposed control methodologies are formulated to accommodate unknown or uncertain system parameters, nonlinearities including the hysteresis effect, and external disturbances in the piezoelectric actuation systems without any form of feed-forward compensation. In this study, both control methodologies are demonstrated to possess a promising motion tracking ability experimentally. In comparison, the variable structure control approach is evaluated to be superior to the adaptive technique in the motion tracking control. With the ability to track motion trajectories under …
Evaluation Of Alternative Water Resources For Cape Coast And Its Environs In Ghana, Alex Kumah
Evaluation Of Alternative Water Resources For Cape Coast And Its Environs In Ghana, Alex Kumah
Electronic Theses and Dissertations
Cape Coast once a national capital of Ghana and its environs in recent years have constantly suffered perennial acute water shortage. The Brimsu dam which takes its supplies from the Kakum River with current production capacity of 1.4 × 104 m3/day cannot meet the water needs of the study area. The operating levels of the dam during crisis have reduced from 7.3 meters to 4.7 meters over the years with subsequent reduction in water production by 35%. Recently, the operating level has reduced further to about 3.5 meters with 60% reduction in water supply. This study evaluated alternative water resources …

With properly designed LIDAR control, assessment of 3D as-builts is attainable with an average over-all horizontal (planimetric) error of 0.324 ft (9.9 cm). Specifically, with an RMS error of 0.284 ft (8.7 cm) in Northing, and 0.255 ft (7.8 cm) in Easting. The average over-all vertical (height) error is 0.003 ft (0.1 cm) with a 0.108 ft (3.3 cm) RMS error. Lidar recognizable control (2m x 2m chevrons) was spaced at approximately 200m parallel to the direction of the axis of the project corridor, and at 60m sideway intervals. The project corridor was about 6 km long. Least Squares Image …
