This paper discusses the addition of a new Department of Mechanical and Energy Engineering at the University of North Texas (UNT). Those involved see the curriculum for this new program as a new model of engineering education that parallels the innovations of UNTs current Learning to Learn (L2L) project-oriented concept course with the addition of innovative approaches for mechanical engineering and emphasis on energy engineering education.
This article discusses elbow tube fitting. Abstract: Safe operation of machinery depends strongly on the design of the system and the employement of proper components and materials. Unique to fluid powered systems are the proper selection of hydraulic lines, fittings, and control valves. This paper describes the cause of fracture in an elbow tube fittings due to deficiencies in the dimensional design and materials selection. The investigation included metallography, fractography, hardness testing and metrology. The results showed that the material was low carbon steel subjected to cold forming and normalized annealing processes during tube production. There were dimensional variations in the tube and the material strength was low.
This paper discusses the electrowetting solar cell. In comparison with traditional silicon-based PV solar cells, the electrowetting-based self-tracking technology will generate ~70% more green energy with a 50% cost reduction.
Poster for the 2011 University Scholars Day at the University of North Texas discussing a study of thermal properties of irradiation-induced stainless steels used in the development of nuclear reactors.
Poster for the 2015 University of North Texas (UNT) Graduate Exhibition. This poster discusses the evaluation of three major emission sources on the Dallas-Fort Worth ozone levels using photochemical modeling.
Presentation for the 2014 Fracturing Impacts and Technologies Conference. This presentation discusses an evaluation of the correlation between shale gas development and ozone pollution within the Barnett Shale region.
This article employs an advanced factor analysis technique with principal component analysis/absolute principal component scores and positive matrix factorization to apportion the sources influencing the PM₂̣ ₅ levels measured during 2003 through 2005 at a rural coastal site located within the Corpus Christi urban airshed in South Texas.
