Automated systems have become increasingly important to human decision making and task performance in a wide variety of complex fields and situations. Decision aids, a specific form of automation, assist human operators in making complex decisions under conditions of uncertainty, such as air traffic control or combat identification. When humans...
Travel demand has increased due to population growth, increase of vehicle ownership, and development patterns resulting in greater levels of congestion, pollution, and crash frequency. One approach to demand management is to increase the share of trips made by bicycles. With the increase in bicycling rates, there is a critical...
An innovative silver nano-dimple arrays (Ag DAs)-integrated microfluidic device was developed to achieve highly sensitive fluorescence-based nucleic acid detection. The Ag DAs were utilized to produce surface plasmon resonance (SPR) for strong fluorescence enhancement. We systematically investigated the plasmon-enhanced fluorescence by controlling the nanostructure dimension of the Ag DA substrate....
Human error is responsible for the majority of accidents in complex environments including helicopter operations. To reduce the overall accident rate throughout the helicopter industry, we must first understand how helicopter missions differ from one another and what errors lead to accidents.
The research documented in this dissertation involved a...
Rural students have lagged behind non-rural students in matriculation into higher education, as well as in completion of four-year degrees. The current studies sought to investigate academic readiness, academic performance, and psychological differences between rural and non-rural students at Oregon State University. Rural and non-rural students were compared during spring...
Funk’s (1991) cockpit task management (CTM) theory is structurally consistent with cognitive multitasking models: it addresses managing multiple and concurrent tasks in three stages: situation awareness, response selection, and response execution. Based on CTM theory, Colvin, Funk and Braune (2005) hypothesized that the following six factors may affect task prioritization:...
Visual information presented in diagrams promotes information processing both in an individual and in collaborative work. Previous literature has identified the role of diagrams in
understanding information processing in a variety of disciplines. In software engineering, diagrams are a prevalent method involved in process development: diagrams are used for system...
Distractions and interruptions are common occurrences in an operating room (OR), but little is known about their effects on surgical task performance. Based on human factors research, it was hypothesized that realistic distractions and interruptions in an OR would adversely impact surgical task performance. Because of the concern of patient...
Although there has been a rapid growth in online apparel sales and online apparel shopping during the last several years, consumers still have concerns when they purchase apparel products online (ComScore, 2007; Dunne & Lusch, 2005; ITFacts E-commerce, 2007). From the online apparel shoppers’ perspective, online apparel shopping involves a...
AES (Advanced Encryption Standard), also known as Rijndael, is a symmetric key block cipher adopted as an encryption standard by the US government and used extensively in cryptographic applications worldwide. ARM is the most popular processor core used in embedded applications. This thesis surveys the available public implementations of AES...
