The historical records of White Glacier (WG), a polythermal valley glacier found in northern Nunavut, Canada, are used alongside modern structural models and orthomosaics produced from Structure from Motion photogrammetry to assess change in the terminus region. Recognizing the …
A fundamental task for any visual system is the accurate detection of objects from background information, for example, defining fruit from foliage or a predator in a forest. This is commonly referred to as figure-ground segregation, which occurs when the visual system locates d…
The wireless industry is growing very fast in the last decade with the main aim of high-speed, low-latency, and reliable communication. Localization, being a primary and essential component of wireless communication, needs to be efficient enough to match modern requirements. Wit…
Understanding the spatial and temporal dynamics of soil water and crop water stress within a field is critical for effective Variable Rate Irrigation (VRI) management. Proper VRI can result in improved protection of the crop from early onset of crop water stress while minimizing…
Predictive maintenance aims to minimize the downtime due to maintenance, while simultaneously minimizing the risk of unforeseen failures. Efforts in predictive maintenance have been focused on predicting the remaining useful life of a machine. There is need for a more comprehens…
Existem inúmeras minas desativadas que apresentam um elevado valor patrimonial e histórico. Contudo a maioria destas minas acaba por não ser documentadas com o devido cuidado, existindo o risco de deterioração do património com o passar do tempo, pelo que se torna necessária a e…
Bathymetric mapping is an important tool for reservoir management, typically completed before reservoir construction. Historically, bathymetric maps were produced by interpolating between points measured at a relatively large spacing throughout a reservoir, typically on the orde…
Cílem práce je porovnání a zhodnocení využití několika metod používaných pro určení složení historických materiálů, zejména těch využívajících odrazivostní spektrometrii a hyperspektrálním snímkování. Tyto metody jsou ve své podstatě neinvazivní, a proto velmi zajímavé pro dokum…
Sonochemical growth of zinc oxide (ZnO) nanowires and nanowalls is a relatively new synthetic technique that allows for room ambient growth and large scale production. This synthesis technique allows for services ranging from gas sensors and UV switches. In comparison to the wid…
Intelligent transportation systems use in-pavement inductive loop sensors to collect real time traffic data. This method is very expensive in terms of installation and maintenance. Our research is focused on developing advanced algorithms capable of generating high amounts of en…
Oil and gas (O&G) explorations are moving into deeper zones of earth, causing serious safety concerns. Hence, sensing of critical multiple parameters like high pressure, high temperature (HPHT), chemicals, etc., are required at longer distances. Traditional electrical sensors op…
This thesis is about the relationship between human bodies and instrumental technologies that can be use to measure them. It adopts the position that instruments are technological structures that evoke and manifest particular phenomena of embodied life. However, through their hi…
Cubic Polyhedral Oligomeric SilSesquioxanes (POSS) of general formula Si₈O₁₂R₈ (R = alkenyl, alkoxy, aryl, hydrogen...) have found applications in various fields ranging from biology to chemistry. Besides the advantage of presenting the characteristic dendritic globular shape at…
Sustained stimulation of sensory organs results in adaptation of the neuronal response along the sensory pathway. Whether or not cortical adaptation affects equally excitatory and inhibitory inputs is poorly understood. This question was examined using patch recordings of neuron…
Semiconductor field effect sensors have been shown to enable the possibility of realizing cost effective, highly dense label-free sensors for the detection of chemical and biological species. Such sensors can be readily integrated with existing platforms for micro total analysis…
The main objective of this dissertation is to comprehensively analyze vibration characteristics of microcantilever-based sensors with application to ultra small mass detection and low dimensional materials characterization. The first part of this work focuses on theoretical deve…
To facilitate rapid detection of potential bioterrorist agents, development of an inexpensive, adequately sensitive and specific, user-friendly, robust, and rapid field-based biosensor is advantageous for preventing the spreading of infections. In this study, fabrication and per…
Organizations concerned with human rights are increasingly using remote sensing as a tool to improve their detection of human rights and international humanitarian law violations. However, as these organizations have transitioned to human rights monitoring campaigns conducted ov…
