The Eco-Smart Can V2.0, Darack B. Nanto

Appalachian Student Research Forum

I noticed that the workers had the same itinerary when emptying trashcans, meanwhile trashcans needed urgently to be emptied. Traditionally, ETSU maintenance operate on daily routes to pick trash on designated time, regardless the level of the containers. This leads to overflown trashcan in busy areas or during rush hours in certain areas. This overflown trashcan result in an unclean environment for the community and an unpleasant look of our beautiful campus. The time, resources and labor invested in collecting the trash could be saved. Therefore, I decided to use the Internet of Things (IoT) to create a device that …

Respirable Dust Monitoring In Construction Sites And Visualization In Building Information Modeling Using Real-Time Sensor Data, Nour Smaoui, Kyungki Kim, Omprakash Gnawali, Young-Joo Lee, Wonho Suh

Durham School of Architectural Engineering and Construction: Faculty Publications

Construction activities, involving cutting, drilling, and grinding of materials, often produce toxic respirable dust that can cause fatal diseases and illnesses. To protect workers from breathing excessive amounts of respirable dust at job sites, superintendents should continuously monitor the level of respirable dust in workspaces and make timely interventions for overexposed workers. However, current practices of respirable dust monitoring have critical drawbacks, and superintendents cannot accurately estimate workers’ exposures to respirable dust or make prompt decisions to protect the workers. Therefore, there is a need for real-time air dust monitoring that can be deployed ubiquitously at a construction site and …

Influence Of Atmospheric Clearness On Pdlc Switchable Glazing Transmission, Aritra Ghosh, Brian Norton, Tapas K. Mallick

Articles

Electrically activated switchable polymer dispersed liquid crystal (PDLC) is suitable for adaptive windows. A particular type requires 20V to become 71% transparent while in the absence of power it is 27% transparent. Glazing transmission changes with light incident angle. As the clearness of a sky changes the fraction changes alter of direct insolation (that has an azimuthally changing incident) and diffuse insolation (that has a largely constant incident). Thus, the effective overall incident angle determining the glazing transmittance also changes. In this work for the first time, the variation of PDLC glazing transmission with clearness index has been investigated.

A Constructivist Approach To The Use Of Case Studies In Teaching Engineering Ethics, Diana Adela Martin, Eddie Conlon, Brian Bowe

Articles

Our paper aims to explore the effectiveness of a constructivist approach to the teaching of engineering ethics through case studies, by putting forward a contextualization of the much discussed case study “Cutting Road Side Trees” (Pritchard, 1992) in light of the constructivist frame suggested by Jonassen (1999). First, we briefly analyse how the use of case studies for the teaching of engineering ethics eludes the complexity of the engineering professional environment before arguing that constructivism is a learning theory that can help to address this complexity. The final section proposes a constructivist reworking of the case method in a manner …

Nádúr Daonna (Natureza Humana): An Intervention To Work With Nature In The Intellectual Development Of First Year Engineering Students, Domhnall Sheridan, Michael Carr

Conference papers

For most of the 20th Century there has been a debate among psychologists, educationalists and others as to whether nature or nurture determined the personality and capabilities of the adult person. Only in the last decade has an answer been found for that perennial question: the adult is the product of both nature and nurture. The genotype, the genetic inheritance from parents provides a template, but the expression of the genotype, the phenotype, depends on the interaction between the individual and their environment. Nothing is written in stone: the young child beginning education has almost infinite possibilities. In order for …

Mens Sana: An Investigation Into The Relationship Between Psychological Traits And Academic Success Of First Year Engineering Students, Domhnall Sheridan, Michael Carr

Conference papers

In 1904, the French government asked the psychologist Alfred Binet to devise a general test of intelligence that could be used to identify pupils who were behind their age cohort, in order to give them extra help to bring their level up to that of their peers. For most of the 20th century, intelligence testing has played a major role in education, unfortunately to categorize pupils at an early stage in the life, rather than to help them. In the last two decades, much work has been done in broadening the testing of students, especially in examining the relationship between …
