UWB localization for autonomous indoor position control of VTOL UAVs
(2018)As the popularity of quadrotor Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) grows, the need for reliable position estimation and control grows as well. Furthermore, with the size of these quadrotors ... -
Validation of discrete ordinate radiation model for application in UV air disinfection modeling
(2014)This study investigated one of the most important aspect of ultra-violet (UV) air disinfection modeling which is radiation modeling. Radiation modeling is a topic of interest in the domain of UV air disinfection research. ... -
Valorization of Kraft lignin via alkaline and acid- mediated aerobic oxidation processes
(2023)Lignin is a complex heterogeneous aromatic compound derived from renewable plant biomass. Due to its aromatic backbone, it has grown interested in producing biochemicals and other polymeric applications. Depending on the ... -
Vapnik-Chervonenkis dimension in neural networks
(2023)This thesis aims to explore the potential of statistical concepts, specifically the Vapnik-Chervonenkis Dimension (VCD)[33], in optimizing neural networks. With the increasing use of neural networks in replacing human ... -
Variability in women's perception of potential female rivals: effects of fertility, mating orientation, and revealing dress biases
(2017)Two studies were conducted to better understand individual difference factors that influence women’s mating-relevant perceptions of other women. In Study 1, biases about revealing dress were examined and the extent to which ... -
Variation in vessel diameter and leaf area of white birch (Betula papyrifera) along moisture gradients in Canada
(2010)One of the key hypotheses of this research is that white birch that has evolved in wet areas will have larger vessels than those trees that evolved in dry areas. Since the wet areas are less likely to experience drought ... -
Vibration control using switchable stiffness
(2015-01-13)Over the last decade, the switchable stiffness (SS) control strategy has seen renewed academic interest due to the need for effective vibration control techniques. The SS control strategy involves switching the system’s ... -
Vibration suppression and energy harvesting with a variant nonlinear energy sink
(2018)Vibration control is aimed to suppress or eliminate unwanted vibration to ensure proper operation of machines. On the other hand, energy harvesting intends to scavenge energy from ambient vibrations to power electronical ... -
Violence and masculinity in Hollywood war films during World War II
(2013-02-03)During World War II, the Hollywood studios produced an unprecedented number of war-themed films in order to help prepare American audiences for what was to come, as well as to profit from the popularity of anything pertaining ... -
Virtual work from home and mental health: a mixed methods systematic review
(2021)Poor mental health is a risk factor for a number of chronic physical conditions and may impact individuals’ ability to remain in the work force (World Health Organization, 2004b). Further, the workplace itself may pose ... -
Visible light positioning systems under imperfect synchronization and signal-dependant noise
(2022)Optical Wireless Communication (OWC) is an enabling technology for sixth-generation (6G) and beyond communication networks. Visible light communication (VLC) is a crucial branch of OWC technology expected to meet 6G ... -
Vision-based control and autonomous landing of a VTOL-UAV
(2015-10-21)In recent years the popularity of quadrotor unmanned aerial vehicles (UAVs) has increased. Today, UAVs are widely used by military and police forces for surveillance. They are used by industry for such tasks as traffic ... -
Visitors' attitudes towards wind farms : a study of the English Lake District National Park
(2011-07-19)The tourism industry is one of the largest in the world. Many nations derive considerable economic gain from tourism markets. At the same time, many nations are pushing for the development of newer greener sources of energy ... -
Visuo-perceptual task performance across the menstrual cycle in women with and without premenstrual symptoms: potential influences of estradiol and estradiol sensitivity on retinogeniculostriate, extrastriate, and elementary retinal-based smooth pursuit pathways
(2012-11-10)The present study examined whether women with premenstrual symptoms (PMS) exhibit a different pattern of performance on psychophysical tasks across the menstrual cycle in comparison to control women. Research has shown ... -
