However, in some applications such as gas, oil, and solar water heaters and heating, ventilation, and air conditioning (HVAC) systems, corrosion properties need to be further improved through new surface coatings for enhanced protection against corrosion, degradation, and abrasion. In many cases, a duplex coating system is used to provide extra protection against corrosion and degradation. In this study, steel sheet samples with varying levels of protective zinc coating thicknesses were individually tested as well as in conjunction with polymeric-based paint coatings through equal exposure times in a salt spray chamber for several days. Corrosion and mechanical testing of varying zinc coatings, especially in duplex systems are hardly available in the literature reviews, and this study reports new findings in the HVAC field. The prepared samples were kept in a salt spray chamber for different time frames (250 -- 1000 hours), and the effects of corrosion damages over time were investigated. Before and after the evaluations, all the sheet samples were subjected to tensile testing to study the changes in mechanical properties. It was discovered that duplex coating systems that involve a zinc coating with an organic polymer-based powder coat or pre-painted finishes on metal sheets (G30, G60, and G90) showed little or no sign of corrosion degradation over time, and therefore experience substantially fewer property changes. However, the surfaces of the uncoated or one-layer coated samples were severely damaged in the salt spray chamber, reducing the lifetime of the HVAC system. It is concluded that the duplex system provided better corrosion and chemical resistance against environmental degradations.Item Challenges to the implementation of lean practices in higher education: Is the culture in higher education conducive to adoption of lean principles and philosophy?(Association for Industry, Engineering and Management Systems (AIEMS), 2022-12) Kluse, Christopher; Shannon, Chris J.Lean in higher education, often abbreviated as LHE, has grown in interest over the past 20 years. The application of lean principles has been observed in higher education institutions throughout the world. Many researchers have investigated both the success and the failure of lean in higher education. Although lean originated in the automotive industry, and both the automotive industry and higher education report success and failure, there is no comparison of the factors between these groups. Culture is cited quite frequently in the literature as a barrier to success. Thus, there is a need for investigation into the cultural differences between higher education and the automotive industry as they relate to lean. This paper uses Schein's three elements of culture to evaluate the differences in culture between higher education and the automotive industry. It concludes with recommendations on how to best deploy the practices of lean in higher education given the cultural differences and challenges between the two sectors.Item Business analytics at Florida commuter colleges: The impact and effectiveness of implementing a business analytics program(Association for Industry, Engineering and Management Systems (AIEMS), 2022-12) Gooden, Joachim P.; Ford, Rakeem R.; Black, Jason T.Only forty of Florida's one-hundred seventy-eight colleges and universities are public, meaning the vast majority are privately run. Many of these schools provide associate degrees or certificates (Community College Review, 2021). Commuter colleges hold the distinction of providing off-campus student living, with the majority offering two-year degrees. Despite the growing need in industry for individuals who can manage large amounts of data, commuter colleges rarely offer business analytics courses, causing many students to miss out on such employment opportunities. Most businesses struggle with analytical planning and are looking for experts who can turn data into insight (Albright & Winston, 2016). The absence of data analytics capabilities causes organizations to waste data resources at a rate of approximately sixty to seventy percent (Forrester, 2017). Intrinsically, universities of all sizes, including commuter colleges, need to train and produce more data analysts. Many major universities now offer business analytics degrees, yet business analytics degrees are available at less than twenty percent of commuter colleges. The goal of this research is to investigate whether commuter colleges would indeed benefit from business analytics programs and to determine the appropriate analytics degree curricula most optimal for these types of institutions. The paper will present an exhaustive comparison of the state of Florida's colleges and universities, including commuter colleges, examining both business intelligence and business analytics degree programs. The objective is to analyze the impact and effectiveness of these programs at larger universities and present a model for developing such programs at commuter colleges.Item Effects of functional nanomaterials for reduction of carbon monoxide levels in the workplace and homes(Association for Industry, Engineering and Management Systems (AIEMS), 2022-12) Asmatulu, Eylem; Pham, AnhCarbon monoxide (CO) at high concentrations is extremely poisonous to humans and other invertebrates. It is one of the leading causes of unintentional deaths in the United States. Furthermore, people with heart diseases are more vulnerable to high CO levels since they already have a reduced ability to get oxygenated blood to their hearts. Functional nanomaterials (metallic nanoparticles [NPs], carbon nanotubes [CNTs], and nanofibers [NFs]) offer a high surface area, low weight-to-volume ratio, flexibility, and high porosity, which are perfect properties for gas absorption. Many nanomaterials are currently playing an essential role in CO-capturing technologies. This paper focuses on the usage of those functional nanomaterials for CO absorption and their absorption mechanisms. Due to high surface area and porosity, these materials have been widely used to absorb pollutants, including toxic gas like CO. Fabrications, CO-absorbing mechanisms, and absorbing properties of some nanomaterials will be discussed here.
