Non-GPS localization has gained much interest from researchers and industries recently because GPS might fail to meet the accuracy requirements in shadowing environments. The two most common range-based non-GPS localization methods, namely Received Signal Strength Indicator (RSSI) and Angle-of-Arrival (AOA), have been intensively mentioned in the literature over the last decade. However, an in-depth analysis of the weighted combination methods of AOA and RSSI in shadowing environments is still missing in the state-of-the-art. This paper proposes several weighted combinations of the two RSSI and AOA components in the form of pAOA + qRSSI, devises the mathematical model for analyzing shadowing …

Analog Least Mean Square (ALMS) loop is a promising method to cancel self-interference (SI) in in-band fullduplex (IBFD) systems. In this paper, the steady state analyses of the residual SI powers in both analog and digital domains are firstly derived. Eigenvalue decomposition is then utilized to investigate the frequency domain characteristics of the ALMS loop. Our frequency domain analyses prove that the ALMS loop has an effect of amplifying the frequency components of the residual SI at the edges of the signal spectrum in the analog domain. However, the matched filter in the receiver chain will reduce this effect, resulting …
Julia De Burgos, Embodied Excess, And (Un)Silenced Memory: A Decolonial Feminist Analysis Of Performances Of Resistance, Sara Johanna Baugh
Julia De Burgos, Embodied Excess, And (Un)Silenced Memory: A Decolonial Feminist Analysis Of Performances Of Resistance, Sara Johanna Baugh
Electronic Theses and Dissertations
My dissertation makes an argument for a decolonial move in rhetorical memory studies to more ethically account for the ways in which colonized women in the Global South, like Puerto Rican poet and revolutionary Julia de Burgos, have resisted the trauma colonization has systemically wrought against gendered, raced, and classed bodies. Building from a decolonization methodology, and theoretically situating my argument in Chicana, Latina, and decolonial feminisms, I argue Burgos's poetry both bears faithful witness to the violence of US imperial rule and articulates the dangers of a Puerto Rican nationalist movement built on a Spanish colonial foundation. Approaching Burgos …
"Femme Fatales Of Faith": Queer And "Deviant" Performances Of Femme Within Western Protestant Culture, Kelsey Waninger Minnick
"Femme Fatales Of Faith": Queer And "Deviant" Performances Of Femme Within Western Protestant Culture, Kelsey Waninger Minnick
Electronic Theses and Dissertations
Women and queer folk are changing the religious landscape of Christianity in America, and the scope of visibility for these figures and their apostolic endeavors is widening as more and more Christians are seeking out communities rooted in doctrines of love and connection rather than exclusion and hegemonic piety. Thinking on this phenomenon, this dissertation focuses on the intersectional dilemmas of faith practice and rhetorical discourse with Western Christianity, particularly as it revolves around those female pastors and clergy - considered "dangerous" by many within the church - who are advocating for a more inclusionary church space. By conducting a …
Performance Simulation And Evaluation Of Net Zero Energy Buildings In An Australian Coastal Climate, Joel Anderson, Duane A. Robinson, Zhenjun Ma
Performance Simulation And Evaluation Of Net Zero Energy Buildings In An Australian Coastal Climate, Joel Anderson, Duane A. Robinson, Zhenjun Ma
Faculty of Engineering and Information Sciences - Papers: Part B
Net zero energy buildings (NZEB) are becoming more common, and as new energy saving designs and technologies become available, the ability to estimate overall energy use and understand the impact on operation of building appliances will become important. This paper outlines simulation results of performance improvements achieved by modifying various components (glazing, lighting, thermal comfort settings) of two tertiary education NZEBs and a typical modern commercial building. The DesignBuilder models' thermal performance and energy consumption were validated using real data from case study buildings. The work shows validating models of smaller, less conven-tional, buildings is more difficult than for larger …
Space On Par: A Short Performance For One Performer, Peta Tait
Space On Par: A Short Performance For One Performer, Peta Tait
Animal Studies Journal
Space on Par is a short performance text that uses gentle humour to communicate an alternative perspective on how open space is used by humans and nonhuman animals, in this instance a golf course. If playing golf for enjoyment is puzzling behaviour for a nonhuman observer, it can emphasise human refusal to recognise the physical and spatial rights of other species and their needs for survival. The effort to educate about the treatment of animals can include theatrical characters who blur the species identities to make a point, and Space on Par inverts the invisibility of the gaze of the …
Dual Effects Of Tisio4composite Nanoparticles On Dispersionstability And Lubrication Performance Of Vegetable Oil‐In‐Water Emulsions, Reza Taheri, Buyung Kosasih, Hongtao Zhu, Anh Kiet Tieu
Dual Effects Of Tisio4composite Nanoparticles On Dispersionstability And Lubrication Performance Of Vegetable Oil‐In‐Water Emulsions, Reza Taheri, Buyung Kosasih, Hongtao Zhu, Anh Kiet Tieu
Faculty of Engineering and Information Sciences - Papers: Part B
Vegetable oil-in-water emulsions are potential metal-working lubricants. These emulsions are susceptible to oil-water phase separation due to the oil droplets' coalescence. In this study, we enhance the dispersion stability and lubricity of such emulsions with TiSiO4 nanoparticles (NPs). With 1 vol% soybean oil, stable emulsions are obtained with 0.25 to 0.75 wt% NPs, attributed to formation of shielding layers of NPs around the droplets. Lowest friction and wear are obtained without and with 0.25 wt% NPs, respectively. With increasing the NPs' mass fraction, NP-shielded droplets become less attracted to metal surfaces. Association of NPs within boundary film is also found …

Transition from onefold to synergistic lubrication for solving fretting wear and fatigue problems is of great practical significance, because fluids can regulate fretting regime for minimizing wear, solid films can restrain nucleation and formation of crack. Here synergistic lubrication coatings were prepared using diamond-like carbon (DLC) and molybdenum disulfide (MoS2) films as anti-wear/fatigue layer, and high-performance lubricants (including silicone oil, ionic liquids, multialkylated cyclopentanes and perfluoropolyethers (PFPE)) as flowable lubrication layer. Their fretting performance was evaluated in detail and fretting mechanism was revealed by surface/interface analysis techniques. Results determine the synergistic lubrication coatings with good anti-wear and anti-fatigue abilities, deriving …

Study On Performance Evaluation Of Co2 Heat Pump System Integrated With Thermal Energy Storage For Space Heating, Zhihua Wang, Yuxin Zheng, Fenghao Wang, Mengjie Song, Zhenjun Ma
Faculty of Engineering and Information Sciences - Papers: Part B
CO2 heat pumps have drawn a great deal of attention owing to their advantages of high efficiency and environmental friendly for heating water under low ambient temperature. However, the system performance is not desirable and shows a lower COP for space heating, especially for a radiator as heating terminal, due to the higher inlet water temperature at the gas cooler, which causes a large throttle loss when the refrigerant flow through the throttling device. To tackle this issue, a transcritical CO2 heat pump system integrated with thermal energy storage (TES) systems was developed in this paper. The heating performance of …

Biodegradable prefabricated vertical drains (BPVD) made from naturally occurring materials such as jute and coconut (coir) fibre not only have favourable engineering characteristics but also not detri-mental to the natural environment thanks to their biodegradability. Although the use of these natural fibre drains has been proposed for several decades, their application is still very limited. One of major reasons for this is because they are usually composed of individual fibres with large openings which can trap fine soils while discharging pore pressure, consequently reducing the hydraulic conductivity of the drain. This study therefore aims to clarify how soil can clog …

Faculty of Engineering and Information Sciences - Papers: Part B
Track transitionssuch as bridge approaches, road crossings and shifts from slab track to ballasted track are common locations wheretrack degradation accelerates due to dynamic and high impact forces; as a consequence there is higher differential settlement. Thesetypes of discontinuities cause an abrupt change in the structural responseof the track due mainly tovariations in stiffness and track damping. Track transitionzones are prone to an accelerated deterioration of track material and geometrythat leads to increased maintenance costs.Track deteriorationalso leads to vehicle degradation due to enhanced acceleration, low frequency oscillation, and high frequency vibrations. While ballastdeterioration is amajor factor affecting thestability and longevity …
Examining The Utility Of The Hexaco-Pi-R For Predicting Positive And Negative Indicators Of Police Officer Performance, Angela Marie Ripley
Examining The Utility Of The Hexaco-Pi-R For Predicting Positive And Negative Indicators Of Police Officer Performance, Angela Marie Ripley
Walden Dissertations and Doctoral Studies
Identifying behaviors that are either counterproductive work behaviors (CWBs) or organizational citizenship behaviors (OCBs) may assist law enforcement agencies in selecting and aligning police officers for the various roles asked of them. The 6 dimensions of personality are not currently being used in law enforcement agencies to predict overall job performance of police officers. The purpose of this quantitative study was to examine the extent to which the 6 personality dimensions as measured by the HEXACO Personality Inventory Revised (HEXACO-PI-R) predicted overall indicators (OCB and CWB) of police officer job performance. A sample of 51 police officers from a variety …

Speech Interfaces And Pilot Performance: A Meta-Analysis, Kenneth A. Ward
International Journal of Aviation, Aeronautics, and Aerospace
As the aviation industry modernizes, new technology and interfaces must support growing aircraft complexity without increasing pilot workload. Natural language processing presents just such a simple and intuitive interface, yet the performance implications for use by pilots remain unknown. A meta-analysis was conducted to understand performance effects of using speech and voice interfaces in a series of pilot task analogs. The inclusion criteria selected studies that involved participants performing a demanding primary task, such as driving, while interacting with a vehicle system to enter numbers, dial radios, or enter a navigation destination. Compared to manual system interfaces, voice interfaces reduced …
The Mediation Of Affect On Imagery Use And Self-Efficacy In Collegiate Athletes, Michelle Wirbiezcas
The Mediation Of Affect On Imagery Use And Self-Efficacy In Collegiate Athletes, Michelle Wirbiezcas
Electronic Theses and Dissertations
In the sports domain, research has become an essential part of how we understand the psychological factors that play a key role in maximizing performance. Previous research has suggested that an individual’s performance can be highly influenced by the psychological variable of self-efficacy (e.g., Bandura, 1997; Calmels & Fournier, 2001). Self-efficacy has been used to describe individuals’ perceived capability of achieving a certain level of performance in the domain of sport (Feltz, 1998). Previous research has also demonstrated that the tendency of athletes to interpret their imagery as either facilitative or debilitative affects specific constructs known to enhance or impede …
Being Mindful Of Perfectionism And Performance Among Athletes In A Judged Sport, Erika D. Van Dyke
Being Mindful Of Perfectionism And Performance Among Athletes In A Judged Sport, Erika D. Van Dyke
Graduate Theses, Dissertations, and Problem Reports
Literature pertaining to mindfulness and perfectionism in sport has expanded greatly in recent years. However, little research has integrated mindfulness and perfectionism, particularly within sports where athletes are judged on performance to a standard of perfection. The current study had two primary aims: (1) to explore profiles of mindfulness and perfectionism among intercollegiate gymnasts through a person-centered approach, and (2) to analyze differences in objective performance measures across the resulting profiles. The analytic sample consisted of 244 NCAA gymnasts representing NCAA Division I, II, and III institutions. Gymnasts completed self-report measures of mindfulness and perfectionism. Competitive performance records (i.e., national …
