Roofing Practices And Fall Prevention In The Construction Industry, Hadi A. Shishtar Jan 2018

Roofing Practices And Fall Prevention In The Construction Industry, Hadi A. Shishtar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Roofing is an important profession in the construction industry yet there is a lack of understanding of its safeness. It is generally believed that roofing is an occupation that can be easily practiced by anyone. However, there are many key factors that are associated with roofing, which may impact the lives of roofers who often face major risks at work. According to the Occupational Safety and Health Administration (OSHA), roofing is one of the leading causes of falling deaths among construction workers. The Bureau of labor statistics has reported that roofers are highly exposed to non-fatal injuries. They have also …

Designing And Testing 3-D Printed Wafer-Box With Embedded Pzt Sensors To Identify The Shape Effect On Energy Harvesting, Ahmad Jami Safayet Jan 2018

Designing And Testing 3-D Printed Wafer-Box With Embedded Pzt Sensors To Identify The Shape Effect On Energy Harvesting, Ahmad Jami Safayet

College of Graduate Studies: Theses & Dissertations

Piezoelectric energy has been recently paid attention in the field of alternative energy. Day by day the traditional energy sources including Coal tar and oils are becoming scarce. People are heading to an alternative energy source to meet the future energy demand. Piezoelectric energy is one of the competitive energy sources compared to the conventional renewable energy sources including solar, wind, and geothermal power and so on. This energy production method bears enormous research potential because it can be used as the roadway for a new method of power generation. This research project aimed to identify which shaped wafer-box produced …

Building Information Modeling (Bim) Impact On Construction Performance, David D. John Jan 2018

Building Information Modeling (Bim) Impact On Construction Performance, David D. John

College of Graduate Studies: Theses & Dissertations

This study is designed to address the need for having a measure for Construction Performance on BIM-assisted construction projects. Through this study a new Construction Key Performance Indicator (CKPI) matrix is identified and created by the author. The CKPI could be used to assess BIM-assisted projects. Utilizing a sequential mixed methodology approach, academic and practitioner perspectives are assessed. A qualitative content analysis and quantitative descriptive analysis based on demographics are conducted to establish a better understanding of BIM and Construction Performance. The academic perspective is used to assess the relevance of BIMM and CKPI indicators, and the practitioner perspective is …

Manufacturing Applications Of The One-Dimensional Cutting Stock Problem As A Team Project, Hüseyin Sarper, Nebojsa I. Jaksic Jan 2018

Manufacturing Applications Of The One-Dimensional Cutting Stock Problem As A Team Project, Hüseyin Sarper, Nebojsa I. Jaksic

Electrical & Computer Engineering Faculty Publications

This paper explains the beneficial and practical impact of operations research in two real manufacturing settings. Two manufacturing examples used in student projects were (1) cutting rails (80‘ or 40‘) to manufacture railroad frogs of many sizes and (2) cutting round metal rolls (12‘ to 20‘) to meet customer demands for various lengths of cuts. Student teams in Engineering of Manufacturing Processes and Operations Research courses wrote computer programs. The program first identified all possible patterns that can be cut out of a given stock length. Next, the program created a mathematical model (a text file) as an output. This …

Quantity Surveying Professional Apprenticeships: A Paragon For The Supply Of Talent In The Irish Construction Industry, Eoghan Ó Murchadha, Roisin Murphy Jan 2018

Quantity Surveying Professional Apprenticeships: A Paragon For The Supply Of Talent In The Irish Construction Industry, Eoghan Ó Murchadha, Roisin Murphy

Conference papers

The construction industry in Ireland has undergone considerable change in the last decade, the effect of which has resulted in a legacy malfunction in the construction labour market. The recent construction downturn led to high levels of construction unemployment, resulting in the mass emigration of construction professionals. Additionally, perceptions of job uncertainty in construction deterred new entrants into construction-related training and education programmes such as Quantity Surveying. If a skills gap is allowed to prevail, then there is a tangible threat to the industry’s cost competitiveness. As such, value for money becomes merely theoretical, and the cost to the economy …

The Acquisition Of Knowledge And Expertise In Construction: Understanding Construction Professionals, Lloyd Scott, Sittimont Kanjanabootra Jan 2018

The Acquisition Of Knowledge And Expertise In Construction: Understanding Construction Professionals, Lloyd Scott, Sittimont Kanjanabootra

Conference papers

Education programs these days especially in Construction Management have been designed and updated to response to market and stakeholder needs. However, there still exists a need for educators to understand how construction practitioners develop their expertise. Understanding the development of expertise is essential for providers of university education and training to enable them to develop programs to establish on which new professionals can better develop their appropriate expertise. This paper builds on earlier research and further explores how expertise develops in construction professionals. It also explores the similarities and differences in development of that expertise in construction practitioners from the …

The Impact Of Brexit On Cross-Border Trade By The Construction Sector In Ireland: An Exploratory Study, Tara Brooks, Duga Ewuga, Lloyd Scott, John Spillane Jan 2018

The Impact Of Brexit On Cross-Border Trade By The Construction Sector In Ireland: An Exploratory Study, Tara Brooks, Duga Ewuga, Lloyd Scott, John Spillane

Conference papers

Cross-border co-operation can foster learning and contribute positively to business performance and social cohesion. This paper considers construction firms' economic motivation for co-operation around the Ireland - Northern Ireland border. This area, while impacted by the Brexit uncertainty, shares many of the economic and developmental characteristics of border areas throughout Europe. The purpose of the study is to investigate the impact of Brexit on cross border trade by the construction sector in Ireland and investigate the current tensions and barriers to that sector. A qualitative methodology adopted a literature review and semi-structured interview strategy. Data was collected from purposively selected …

Noise Induced Hearing Loss Accountability On Jobsites Within The Construction Industry, Joseph O. Lamphere Jan 2018

Noise Induced Hearing Loss Accountability On Jobsites Within The Construction Industry, Joseph O. Lamphere

Construction Management

Noise induced hearing loss is a major issue on jobsites within the construction industry. Every day workers are exposed to hazardous levels of noise, but they are not being properly managed to mitigate this issue. Workers have misconceptions about the topic, but more surprisingly are sometimes indifferent to the effects; believing hearing loss is inevitable, or it can be cured with a hearing aide. Construction has inherent dangers that workers have to deal with every day. Hearing loss might not be on the top of their lists, but the effects are permanent, and they cannot be cured with a hearing …

Extraction Of Phase-Resolved Wave Data From X-Band Radar Imagery, Alexandra Simpson Jan 2018

Extraction Of Phase-Resolved Wave Data From X-Band Radar Imagery, Alexandra Simpson

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

Typically, phase-resolved measurements of the sea surface are limited to single-point time series from in situ sensors, or arrays of multiple in situ sensors. The deployment of such devices is costly and time intensive, and the wave data they provide is limited in its spatial coverage and directional accuracy. Several remote sensing options, including optical video and X-Band marine radars, offer the possibility of full 2D reconstruction of the phase-resolved directional sea on spatial scales of kilometers. Ocean waves are visible in radar imagery as the ubiquitous backscatter from short wind ripples is modulated by the longer gravity waves. However, …
