Users curate music playlists based on emotion to focus or relax, so streaming services often create playlists of songs to aid this process. Prior research focuses on generating playlists of a single mood or genre, although a few studies work to construct automatic playlists that transition between the genres of...
When decision makers work collaboratively, their combined performance can exceed the performance of even the best group member working alone. However, despite the potential for performance gains when working in a group, collaborating individuals often show poor coordination and losses of motivation, and are generally inefficient at combining their resources...
Research into the effect of automation on human multitasking performance is primarily focused on Decision Automation (a machine suggesting a certain course of action for a human operator to take) and Action Automation (a machine carrying out a certain course of action on behalf of the human operator) while Acquisition...
The art of software engineering inherently requires high-level problem solving and perseverance, as programmers and designers wrestle with complex design and implementation challenges in the process of turning loose concepts and ideas into working code. In the current developer ecosystem, engineers are commonly incentivized extrinsically by monetary rewards, approval or...
The classical store-and-forward routing has and will continue to be the most important routing architecture in many modern packet-switched communication networks. In a packet-switched network, data is sent in the form of discrete packets that traverse hop-by-hop from a source to a destination. At each intermediate hop, the router stores...
Recent advances in wireless technologies have helped the proliferation of wireless devices, ranging from hand-held devices such as cellular phones to more powerful mobile computing platforms as such laptops [1]. Along with that, the end users’
applications running on these devices, ranging from text message to multimedia applications such as...
The purpose of the study was to investigate practical guidelines based on empirical evidence for effective website design, including both home page and product pages. This research consists of two consecutive empirical studies. Study 1 was one factor (home page design: image- vs. text-oriented home page) between-subjects design with two...
As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and...
The purpose of the present study was to determine consumer perceptions of apparel products in Internet shopping. According to the existing literature, four categories of perceptions play primary roles for apparel shopping consumer decisions: apparel appearance, apparel comfort, fabric characteristics, and apparel fit. The present study aimed to observe how...
Smart weapons promise to provide leap ahead capability with regard to accuracy and engagement range for medium and large caliber projectiles. One of the most critical components of a smart weapon system is its sensor suite that provides position, orientation, and velocity information as the projectile flies down range so...
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...
This research work focuses on the mechanism of 1/f noise in GaAs
resistors on semi-insulating substrates and 1/f noise due to temperature
fluctuations in heat conduction in resistors, diodes, and bipolar transistors. The
goal of this research is to generate accurate models to explain physical origin of 1/f
noise in...
Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...
While there are many ways to evaluate a user interface design, the user's mental workload and situation awareness (SA) are particularly important considerations in the supervisory control of safety-critical systems. Typically, operators of these systems must monitor high-volume, time-sensitive status information. Interface design for this domain can be challenging and...
