Heat Transfer Correlations For Low Approach Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Articles

The experimental performance of an open industrial scale cooling tower, utilising small approach temperature differences (1–3 K), for rejection of heat at the low water temperatures (11–20 °C) typical of chilled ceilings and other sensible air–water heat dissipation systems in buildings, is examined. The study was carried out under temperate maritime climatic conditions (3–18 °C wet-bulb temperature range). Initially a theoretical analysis of the process at typical conditions for this climate was conducted, which indicated that a water to air (L/G) mass flow rate ratio of less than 1.0 was required for effective operation. Consequently for these low L/G ratios, …

Farming Systems Education: Case Study Of Swedish Test Pilots, Lennart Salomonsson, Anna Nilsson, Sofia Palmer, Adam Roigart, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

We describe and analyze a pedagogical experiment that introduced a broad and holistic perspective on complete farming systems, systemic learning tools, and a participatory learning strategy at an early stage in agronomy education. The paper describes the adventure of three students, who came from a conventional agronomy program at the Swedish University of Agricultural Sciences (SLU), who were frustrated with the lack of integrated approaches to the study of agricultural systems and a strong focus on molecular-level processes in their first year of education. They encountered a narrow focus in most courses and the overall curricula of agricultural education that …

Analysis Of Learning Styles Of First Year Engineering Students On Two Level 7 Programmes, Aidan O'Dwyer

Conference papers

This paper investigates the learning styles of first year, Level 7, mechanical and electrical engineering students at DIT, over two academic years, using the index of learning styles survey as developed by Felder and Soloman (1991). Student learning styles on these programmes are compared with the results from other such surveys. The correlation between student performance and their individual learning styles is examined. Knowledge of the strongly visual learning style of these cohorts of students may be used to improve the learning environment.

Energy From The Skies: Empowering Future Generations, Petros J. Katsioloudis, Stella Bondi, Walter F. Deal

STEMPS Faculty Publications

The article discusses the development of photovoltaic technology. The first account of the use of solar power during war in western civilization was in the second century B.C. during the battle of Syracuse with Archimedes' famed Death Ray. In the late 1800s and early 1900s many advances occurred including the invention of solar-powered engines, the discovery of the photoconductivity of selenium and its ability to produce electricity when exposed to light, and the construction of the first solar cells from selenium wafers. Photovoltaic technology was born in the U.S. in 1954 when Daryl Chapin, Calvin Fuller, and Gerald Pearson developed …

A Comparison Of Instructional Delivery Methods Based On Student Evaluation Data, John Hackworth, Carol Considine, Vernon Lewis

Engineering Technology Faculty Publications

Distance Education is an increasingly common educational delivery method. At Old Dominion University, all junior and senior level engineering technology courses are offered via distance education at least once every two years. A majority of courses in the distance education system at this university have three simultaneous delivery methods: on-campus, televised (receiving the course at an off-campus site via satellite video/audio), and internet-based video-streamed.

This paper explores the results of student course evaluation surveys for trends, in particular those trends which can be a result of the mode of delivery. Results of these surveys for 23 courses over a 4-year …

Biomedical Technology: Supporting Movement, Petros Katsioloudis

STEMPS Faculty Publications

According to the National Institute on Disability and Rehabilitation Research, an estimated 8.5 million children 21 years and younger have a disability (Jans & Stoddard, 1999). After about a decade, with the development of new and sophisticated materials (aluminum alloys, titanium alloys, and carbon fibers) and the integration of electronics, it was then possible to significantly improve the performance of prostheses, built with the so-called endo skeletal (or skeletal-modular) method (Mora, Beratni & Pedrotti, 2006).

Persona Comme Outil De Design De Services Interactifs: Principes Et Exemple En E-Maintenance, Ahmed Seffah, Christophe Kolski, Djilali Idoughi

Professor Djilali IDOUGHI

Dans ce papier, nous discutons du rôle du persona comme outil de modélisation et d’analyse de l’expérience utilisateur. Ce concept est issu des travaux de recherche de marketing sur le comportement du consommateur. Sa finalité est une meilleure compréhension et une prise en compte de l’expérience de l’utilisateur final. L’Expérience Utilisateur ou client (UX) est un terme générique désignant une collection d’information couvrant le comportement de l’utilisateur, incluant les connaissances, l’expertise, et les attributs décrivant la personnalité de l’usager. Un cas d’exemple en logiciel comme service pour la e-maintenance illustre l’approche persona. Le Software as a Service (SaaS, logiciel comme …
