    Design, manufacturability, and sustainability analysis of an HCCI combustion engine utilizing gasoline and renewable fuels
    (Industry, Engineering & Conference Management Systems Conference, 2022-03) Davani, Sina; Asmatulu, Ramazan
    The global quest for new forms of energy is constantly growing. Extensive research is conducted to test and analyze new blends of fuels to meet these requirements. Due to the concern about the continued availability of fossil fuels, such as crude oil and natural gas, it has become a worldwide quest to face these challenges with renewable forms of fuels and new approaches to internal combustion (IC) engine designs. The IC engine has established a robust utility in various sectors, such as transportation, agriculture, aerospace, defense, and other small power plants, to name a few. However, not all conventional IC engines have the capability to operate on multiple types of fuels. Blended fuels have proven to have slight lower power outputs with increased CO and CO2 emissions; however, yielding a lower fuel consumption is also a factor. In order to eliminate some of the major fuel issues, we have designed, developed and manufactured homologous charge compression ignition (HCCI) engine system. The benefit of this successful HCCI engine is that it can operate without a spark plug or direct injection while operating on regular gasoline. To prove this, various experiments have been conducted with different engine designs and fuels. This paper will explore the superiority of the HCCI engines over the traditional spark ignition, direct ingestion, and compression engines. These HCCI engines have successfully passed testing on different fuels such as gasoline, rubbing alcohol, and blended E10 gasoline. Because of the high engine performance and efficient burning, low particulate emissions (micro and nanoparticles) are expected from these studies.

    Assessing the usability of a desktop simulator for training Instrument Flight Rules (IFR) procedures
    (Industry, Engineering & Conference Management Systems Conference, 2022-03) Blackford, Molly; Ramp, Katelynn; Jackobsen, Steffen; Carstens, Deborah S.
    The aviation industry has used simulator training devices as an inexpensive and safe alternative to flight training for decades. Many different simulation types have been developed, with varying quality levels in fidelity and realism. The study aim is to evaluate the usability of the RedBird JAY desktop simulator for training Instrument Flight Rules (IFR) procedures. Spradley's (2016) domain analysis is used to identify common themes in the participant's responses. Twelve pilots, holding an FAA private pilot certificate and instrument rating as a minimum and with mixed prior simulator experience, operated a Redbird JAY flight simulator configured with the Cessna 172 using standard analog instruments with a separate horizontal situation indicator (HIS) and Garmin G1000 integrated flight instrument system. Each participant was given three scenarios, consisting of approximately five minutes of flying in identical conditions for all participants. The results and future research areas are discussed in this paper.

    Improving the outcome of Six-Sigma projects with cost engineering approaches
    (Industry, Engineering & Conference Management Systems Conference, 2022-03) Tribby, Dennis J.; Elshennawy, Ahmad
    The objective of this literature review is to expand upon the research associated with relationship between the use of cost engineering approaches and six-sigma project success when designing or redesigning products in the manufacturing industry. The objectives of this literature review are two-fold. First, is to analyze contextual peer-reviewed literature pertaining to the impact of using cost engineering methods and practitioners in six-sigma projects focused on new or redesigned products. Second, to identify the causes and factors for six-sigma and related methodologies failures focused on product design and redesign. As a result of this literature review this research aims to provide a cursory look at discovering research gaps that could be addressed further.

    Construction estimating challenges after COVID 19 - the effect of price escalation and material shortages on construction cost and contract management
    (Industry, Engineering & Conference Management Systems Conference, 2022-03) Haddad, Bashar
    The cost of building materials is imperative for determining the profitability and success of construction projects. This paper focuses on the effect of the COVID 19 pandemic on material prices and the availability of material. The input cost of materials and services utilized in construction rose by 27.4% from April 2020 to August 2021. Typically, the material and equipment costs could reach up to 50-60 percent of the construction project cost. Therefore, the increase in material prices and the availability of material pose a significant risk to contractors' ability to bid and execute projects. Prudent contractors must develop a plan to manage and mitigate the risk of material price escalation at the bidding phase, during contract negotiation, and during the built phase of the project. The researcher provides contractors with risk mitigation strategies at each phase of the project to manage and control price volatility.

    Solar Decathlon design challenge: A collaborative student-community engagement project
    (Industry, Engineering & Conference Management Systems Conference, 2022-03) Mani, Nirajan; Chenot, D. Keith
    To prepare our students for their chosen careers, it is important to provide opportunities that integrate their past studies and apply these through civic engagement. The Solar Decathlon competition sponsored by the U.S. Department of Energy (DOE) can be such a platform that challenges student teams to become involved with their community and apply their knowledge and design highly efficient and innovative buildings. According to the DOE, the Solar Decathlon competition provides participating students with unique training that prepares them for the clean energy workforce; educates students and the public about the latest technologies and materials in energy-efficient design, smart building solutions, and demonstrates to the public the comfort and savings of buildings that combine energy-efficient construction and innovative designs including onsite renewable energy production. Considering the dual benefits of this program, the Engineering Technology final year students at Fitchburg State University have participated in the Solar Decathlon Design Challenge. Under the supervision of faculty, students in coordination with local authorities selected a downtown urban property for redevelopment following the guidelines of the Solar Decathlon project competition. This paper presents the importance and challenges of this type of collaborative community engaged project to enhance the learning opportunities for undergraduate students. Moreover, it highlights the benefits of this type of real-world project in capstone course curricula.
