Real-Time Internal Temperature Estimation And Health Monitoring For Igbt Modules, Ze Wang

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Field experiences have demonstrated that power semiconductor devices, such as insulated-gate bipolar transistors (IGBTs), are among the most fragile components of power electronic converters. Thermomechanical stresses produced by temperature variations during operational and environmental loads are the major causes of IGBT degradation. As the devices are often operated under complex working conditions, temperature variations and the associated damage are difficult to predict during the converter design stage. A promising approach—online health monitoring and prognosis for power semiconductor devices—that can avoid device failure and effectively schedule maintenance has attracted much interest.

This dissertation research focused on real-time accurate internal temperature estimation …

The Discrete Spring Transform: An Innovative Steganographic Attack, Aaron T. Sharp

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Digital Steganography continues to evolve today, where steganographers are constantly discovering new methodologies to hide information effectively. Despite this, steganographic attacks, which seek to defeat these techniques, have continually lagged behind. The reason for this is simple: it is exceptionally difficult to defeat the unknown. Most attacks require prior knowledge or study of existing techniques in order to defeat them, and are often highly specific to certain cover media. These constraints are impractical and unrealistic to defeat steganography in modern communication networks. It follows, an effective steganographic attack must not require prior knowledge or study of techniques, and must be …

Cal Poly Humboldt theses and projects

Microgrids are being investigated across the U.S. as a solution to support greater reliability, resiliency, and security of electricity supply. This thesis evaluates the potential of developing technically feasible and economically viable microgrids for selected customer categories in California.

Customer categories selected for this study are deemed suitable for microgrid applications by previous studies. For a customer to be technically suitable for microgrid adoption, this study defined a minimum energy requirement threshold. In order to determine the economically viable potential, a benefit-cost analysis was done to assess microgrid benefits compared to the base case of exclusive reliance on grid electricity. …

Habitat Use And Movement Patterns Of Two Redwood Forest Salamanders, Aneides Vagrans And Ensatina Eschscholtzii, With An Examination Of The Efficacy Of Pit Tags For Marking Small Plethodontids, Christian Brown

Cal Poly Humboldt theses and projects

The habitat use and movements of small, secretive salamanders are generally poorly understood, in part due to the difficulty associated with marking and recapturing such animals. This study was designed to test the efficacy, both in the laboratory and in the field, of using passive integrated transponder (PIT) tags to mark and track two small-bodied plethodontid salamander species native to coastal northwestern California, Aneides vagrans, the Wandering Salamander, and Ensatina eschscholtzii, the Ensatina Salamander.

Aneides vagrans inhabits tree crowns. Using cover objects and visual encounter surveys, I searched for A. vagrans in the angiosperm understory canopy at least twice …

The Effects Of Bicycling Exercise On The Metabolic Cost Of Walking In Older Adults, Daniel Hugo Aslan

Cal Poly Humboldt theses and projects

Impaired walking performance is a key determinant of morbidity among older adults. A distinctive characteristic of impaired walking performance among older adults is a greater metabolic cost compared to young adults. Specifically, healthy older adults have been shown to have a 15-20% greater metabolic cost of walking compared to young adults. However, a recent study suggests that older adults who routinely run for exercise have a lower metabolic cost of walking compared to older adults who walk for exercise. Yet, it remains unclear if other aerobic exercises such as bicycling elicits similar improvements on walking metabolic cost among older adults. …

An Investigation Of The Hydraulics In A Prototype Pool-And-Chute, Vortex Weir Fishway For Anadromous Fish Passage., Brendan Foster

Cal Poly Humboldt theses and projects

This thesis presents the hydraulic characteristics and simulated passage efficiency of a hybrid pool-and-chute, vortex weir fishway designed by Michael Love & Associates. A physical 1:15 scale model was constructed and evaluated at an 8% slope over three prototype flow rates representing high and medium fish passage flows. The highest velocities and turbulent kinetic energy (TKE) values were concentrated along the fishway centerline at the high and medium flow rate and the pool sides showed lower velocities and TKE. Large eddies spin laterally and longitudinally throughout each pool. The velocity vector directions at the lowest flow rate measured differed from …

Ideas About Nature In American Art And Visual Culture, Mark Graham

Faculty Publications

The stories we tell ourselves about nature deeply influence how we attempt to preserve, use, or restore nature as well as practices of art and art education that are concerned with ecological issues (Cronon 1996). Landscapes are culture before they are nature (Schama 1996). Yet, our ideas about wilderness, nature, landscape, and sustainability are fraught with paradox and debate. For example, Darwin’s fundamental assertions about the human relationship to nature continue to spark theological, political and educational controversies. Some environmentalists caution that our consumerist economy will destroy the planet and that we need to return to a less sophisticated technology …

Neural Networks In Strategic Marketing: Exploring The Possibilities, Kristen Bell Detienne, David H. Detienne

Faculty Publications

A review of the literature indicates that few studies have used artificial neural networks (ANNs) for data analysis in business and marketing research, even though there are many benefits to the use of ANNs. Therefore, this article discusses neural networks (NNs) that can be used in addition to or as an alternative to linear regression for data analysis in strategic marketing. The function and layout of NNs make them ideal for research dealing with nonlinear, incomplete, unspecified, or ‘fuzzy’ data and offer several advantages over linear regression. Unfortunately, in many marketing studies, the information being modeled is far from flawless …

Measuring Actual Behaviors In Hci Research – A Call To Action And An Example, Parker A. Williams, Jeffrey L. Jenkins, Joseph S. Valacich, Michael D. Byrd

Faculty Publications

There have been repeated calls for studies in behavioral science and human-computer interaction (HCI) research to measure participants’ actual behaviors. HCI research studies often use multiple constructs as perceived measures of behavior, which are captured using participants’ self-reports on surveys. Response biases, however, are a widespread threat to the validity of self-report measures. To mitigate this threat to validity, we propose that studies in HCI measure actual behaviors in appropriate contexts rather than solely perceptions. We report an example of using movements that reflect both actual behavior and behavioral changes measured within a health care IS usage context, specifically the …

Political Barriers To Distributed Generation Solar In The Sunshine State, Debra Taylor

Harriet L Wilkes Honors College Theses 2010 - 2019

Scientists agree that human activity, particularly the burning of fossil fuels to produce energy, is a major contributor to climate change. Recent global efforts to curb climate change involve the investment in carbon-cutting renewable energy sources, such as wind and solar. Despite being known as “the Sunshine State,” only 0.26% of Florida’s energy production came from solar sources in 2016. Florida ranks third in the U.S. for rooftop solar potential but only twelfth in the cumulative amount of solar capacity installed. Distributed generation (DG) solar refers to electricity generated near the point-of-use via photovoltaic (PV) solar panels, which includes rooftop …

Toward A Mathematics For Life: Whitehead On Education, William Parker

Harriet L Wilkes Honors College Theses 2010 - 2019

The twentieth century mathematician and philosopher, Alfred North Whitehead, conceived the ideal education to be an adventure of the human spirit whereby the manifold aspects of the individual’s capacities are explored and developed. It’s not clear how much mathematics, viewed as a dry mechanical activity consisting of mere technical calculation, could contribute to education so conceived. Yet Whitehead considered mathematical training crucial for developing mental capacity in its abstract, general, and particular operations. Mathematical activity by its very nature promotes the modes of engagement that constitute the ideal education. Understanding is best facilitated by an education where the particular and …

Policing And Privacy: The Use Of Body Worn Cameras By Law Enforcement Officers, Ian Kaye

Harriet L Wilkes Honors College Theses 2010 - 2019

There is an apparent dilemma concerning the interactions between law enforcement personnel and civilians. In certain instances, law enforcement officers have acted brutally and unlawfully against suspects, or civilians have reported false claims of excessive force. A possible solution to reduce these problems is a policy requiring officers to wear Body Worn Cameras (BWC) while on duty. BWC’s have the potential to diminish excessive force in altercations between law enforcers and the general population. A claim of excessive force or unacceptable behavior and brutality can be disputed or confirmed with video evidence, although video cameras are not completely reliable due …

Incentivized Reviews: An Investigation Of Online Consumer Review Bias, Jesse Darrow

Harriet L Wilkes Honors College Theses 2010 - 2019

Online reviews play an important role in contemporary society, having been used to predict market trends and influence industry changes. In addition, many consumers depend on online reviews when deciding which products to buy. Recently, a large group of online venders have started incentivizing shoppers by providing product discounts in exchange for reviews. Some researchers believe that reviewers who are compensated for writing reviews will publish higher-than-average reviews, which may diminish the overall usefulness of online reviews as genuine predictors of product quality and purchaser satisfaction. First, this paper establishes a method for differentiating and isolating incentivized reviews. Then, this …

Trading Safety For Innovation And Access: An Empirical Evaluation Of The Fda’S Premarket Approval Process, George Horvath

Faculty Scholarship

Congress created the premarket approval process (PMA) to provide a rigorous safety evaluation of high-risk medical devices before they may be sold on the U.S. market. Evaluating a PMA application requires the Food and Drug Administration (FDA) to conduct a lengthy, complex, and costly assessment of the extensive data a manufacturer must submit. But other policy concerns, notably a fear of hampering innovation and a desire to assure timely access to new technologies, have led Congress to relax some of the rigorous data requirements the PMA process imposes on manufacturers. Congress mandates that the FDA employ the “least burdensome” approach …
