A Framework for Virtual Patient Navigation Applications

Chandhoke, Gursimran Singh January 2017 (has links)
According to the Canadian Cancer Society, half of Ontario’s population will be diagnosed with cancer in their lifetime. Many patients being assessed for cancer however become overwhelmed when having to manage information overload, many appointments with different instructions and locations, and recommendations on how to improve their lifestyle. This causes much anxiety and uncertainty among patients. Some cancer assessment clinics offer some guidance in the form of paper-based patient navigators, which provide much reliable information to patients but are limited in terms of dynamic updates to appointments, opportunities for sharing knowledge between healthcare providers and patients, and of patients supporting each other. This thesis proposes a new web-based, mobile, and user-friendly virtual patient navigator application framework named Care Ami, which incorporates the information found in an existing paper-based navigator along with the new features such as remote updates to personal care paths and calendars, personalized navigation guidance, sharing of symptoms/medications information, and peer group support. Unlike existing solutions, Care Ami is configurable to support multiple types of diseases (e.g., lung cancer and breast cancer). This application is evaluated through testing and the usage of heuristic evaluation guidelines related to usability, and a comparison with related work highlights its many benefits.

Implementace ALM - JIRA a Testlink ve společnosti LMC, s.r.o. / Implementation ALM – JIRA a Testlink in LMC, s.r.o.

Sellnerová, Eva January 2009 (has links)
The goal of this thesis is to describe the Application lifecycle management (ALM), with a focus on two aspects of this system. The aspects are: the application for the administration of requirements JIRA and the application for the administration of the testing system Testlink. The basis for this endeavor was my practical experience with the implementation of the process ALM in the company LMC. Application lifecycle management is an essential part of companies focused on management processes for software development and it can thus improve their features, from the defining stage to the installation in the production sphere. In my thesis I focus on the application JIRA, as a replacement tool for the administration of requirements and the application Testlink, which is software for the administration and test management. The result aims to conclude whether these applications fulfilled the initial representations of the company and the requirements in the ALM framework. An evaluation of the positive and negative aspects during implementation is being carried, with a look at the effective implementation into practice. I shall try to define the general areas where eventual failures can be detected during the implementation process and that should be carried in mind during the process.

Measurement of surface displacements and strains by the double aperture speckle shearing camer

Brdicko, Jan January 1977 (has links)
In the testing of materials, structures and structural components it is often desired to determine the surface displacement and strain fields due to some external loading. Numerous optical techniques have been developed for this purpose and successfully used in particular applications. Unfortunately, when the surface deformation is quite large, as is usually the case in practical testing, most of these methods fail and only a few suitable optical interferometric techniques will work. Two of the recently developed techniques that seem to work are based on laser speckle interferometry. The first technique was described in 1972 by Duffy [l] who showed that a Double Aperture Speckle Camera (DASC) is suitable for measurement of a reasonably large in-plane displacement having its direction parallel to the line connecting the two apertures of the camera. A second technique was described in 1973 by Hung [3] . He showed that a Double Aperture Speckle Shearing Camera (DASSC) may be used to measure both the in and out-of-plane strains of planar surfaces. Duffy has not considered the fringe formation by DASC due to the displacement normal to the surface and the displacement normal to the line connecting the two apertures of DASC. Hung, in turn, has not considered the effect on fringe formation of either the in and out-of-plane displacements, or the in-plane strain, which is the partial derivative w,v (see Fig. 3.11 for the definition of w,y). Because of the great potential of DASC and DASSC stemming from their ability to measure displacements and strains over many orders of magnitude, a considerable effort was made to determine the fringe formation of the two cameras due to all displacements and strains occuring in a general deformation of a specimen surface. The theoretical analysis of models of DASC and DASSC was performed and resulted in two "new" equations describing the fringe formation by these cameras. The equations take into account the effect of all displacements , and strains on the fringe formation; in addition, the equations are "symmetric" and the equation governing DASSC reduces to the one governing DASC for the lateral shear set equal to zero. The accuracy of these equations was then verified by a number of simple experiments. Various ways of using the two cameras were proposed so that the unknown displacements and strains in the specimen surface may be calculated from the least number of fringe patterns. Computer programs based on these proposed methods were written and used in several experiments. In all instances the actual and the calculated displacements and strains agreed quite well. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

SECURING SYSTEM AND EMBEDDED SOFTWARE VIA FUZZING

Kyungtae Kim (14212763) 05 December 2022 (has links)
<p>    </p> <p>System software is a lucrative target for cyber attacks due to its high privilege and large attack surfaces. While fuzzing has been proven effective for decades, recent fuzzers still suffer from limited coverage when dealing with real-world system programs, such as OS kernels, firmware due to their unique interfaces, and large input space, etc. </p> <p>In this thesis, we aim to secure various system and embedded software, such as OS kernels, device drivers and firmware, using proposed fuzzing techniques tailored for each system software. First, we present HFL, hybrid fuzzing for the Linux kernel. HFL achieves hybrid kernel fuzzing scheme with a faithful combination of traditional fuzzing and concolic execution. Furthermore, HFL addresses essential challenges in the Linux kernel via three distinct features: 1) converting indirect control transfers to direct transfers, 2) inferring system call dependencies, and 3) identifying nested arguments structures. HFL found 24 previously unknown bugs in different Linux kernels, and achieved higher code coverage than baseline kernel fuzzers. </p> <p>While the security of USB host stacks has gotten lots of attention, USB gadget stacks are left behind, leaving their vulnerabilities unfixed. To secure USB gadget stacks, we propose the first USB gadget stack fuzzing, FuzzUSB. As a stateful fuzzer, FuzzUSB extracts USB gadget state machines from USB gadget drivers, and uses them to achieve state-guided fuzzing through multi-channel inputs. FuzzUSB has found total 34 previously-unknown bugs within the Linux and Android kernels, and demonstrated improved bug-finding efficiency with high code coverage. </p> <p>As USB Power Delievery (USBPD) is becoming prevalent, but vulnerable to cyber attacks, there is an increasing need for its security. To achieve secure USBPD communications, we propose FuzzPD, the first black-box USBPD fuzzing technique. FuzzPD leverages a dual-role state machine extracted from USBPD specifications. Guided by the dual-role state machine, FuzzPD performs multi-level mutations, not only achieving state-coverage guided mutation for inter-state exploration, but also leveraging input seeding especially for in-state mutation. FuzzPD discovered 45 USBPD bugs in total, ranging from over-charging bugs to memory access violation. </p>

Medical Cannabis for Chronic Pain: A Retrospective Review of Observational Data

Giangregorio, Aidan January 2021 (has links)
Chronic pain is a debilitating condition that affects 1 in 5 adults globally. An increasing number of people living with chronic pain are using medical cannabis for symptom relief, however, the therapeutic potential of medical cannabis for treating chronic pain is debated. We conducted a retrospective cohort study examining cannabis use for the management of chronic pain using anonymous archival data obtained from the medicinal cannabis tracking app, Strainprint®. Multilevel models were used to analyze data from 741 users in which inhaled, and orally consumed cannabis was used to treat symptoms of chronic pain. In our adjusted model, greater pain relief was associated with male sex vs. female (-0.69 cm on a 10 cm visual analogue scale [VAS]; 95%CI -0.46 to -0.91 cm), joint pain vs. muscle-related pain (-0.05 cm; 95%CI -0.01 to -0.08 cm), and high THC vs. high cannabidiol [CBD]) products (-0.08 cm; 95%CI -0.01 to -0.14 cm); but no significant association with age (-0.008 cm; 95%CI 0.09 to -0.10 cm), nerve pain vs. muscle pain (-0.03 cm; 95%CI 0.02 to -0.08 cm), or the route of administration (inhaled vs. oral, -0.05 cm; 95%CI 0.002 to -0.1 cm). There was a significant interaction with duration of use and product type; specifically, greater pain relief was associated with prolonged use of balanced products (THC & CBD) vs. high CBD products (-0.009 cm; 95%CI -0.003 to -0.01 cm). Overall, medical cannabis provided large improvements in chronic pain symptoms. / Thesis / Master of Science (MSc)

Development of Electrohydrodynamic (EHD) Liquid Micropumps for Electronics Cooling Applications

Kazemi, Pouya January 2007 (has links)
This thesis is missing page i, all other copies are missing this page as well. - Digitization Centre / Emergence of efficient cooling techniques has been a crucial factor in development of faster and more powerful electronic equipment and ICs. One of the key obstacles towards further miniaturization is efficient heat removal from regions of high temperature to maintain continued operation of these devices below their maximum operating range. Recently, a significant amount of research has been directed to develop liquid based cooling techniques. For example, microchannel heatsinks have been designed to remove up to 1 kW/cm2. Developing microscale actuators that provide sufficient pressure head is essential for integrating these microscale cooling schemes with the electronic devices. Different techniques can be used to pump fluid in the microscale such as electroosmotic, magnetohydrodynamic, and electrohydrodynamic (EHD) pumping. Among these technologies, EHD pumps are particularly promising for microfluidic devices because they use no moving parts, and uses very small power and has low cost and maintenance requirements. This work presents the development and test of EHD micropumps with different electrode configurations. Four different electrode configurations: (1) planar symmetric electrodes, (2) planar asymmetric electrodes, (3) 3-D symmetric electrodes, and (4) 3-D asymmetric electrodes were investigated. In addition, the effect of different design specifications, such as the inter-electrode spacing and spanwise spacing of the micropillars were investigated. The electrodes were fabricated using a two mask process. First, a thin layer of chromium was deposited on glass as a seed layer for gold electrodes. Positive photoresist (AZ P4620) was patterned to form the mould for the micropillar electrodes. Nickel was electroplated to fill the mold. Subsequently, a Cr/Au layer was patterned to devise the electrode base connector and pads. The microfluidic channels were fabricated by casting polydimethylsiloxane (PDMS) on top of an SU-8 100 (MicroChem Corp.) mould which was patterned to delineate the microchannel structure. The PDMS microchannel was integrated on the electrode base by plasma oxidizing the PDMS and glass wafer, and sealing the connection with liquid PDMS. The pump performance was experimentally determined with Methoxynonafluorobutane (HFE-7100) as the working fluid. All of the micropumps were tested under a no net flow condition to find the maximum pressure generation. The micropumps with planar and asymmetric planar electrode configurations were also tested for maximum flow rate under no imposed back pressure. The results show that the micropumps with the 3D asymmetric electrode design generated a higher pressure head compared to the other micropumps with identical inter electrode spacing under no flow conditions. The micropumps with planar asymmetric design had a higher performance compared to the micropumps with planar asymmetric electric under both no flow condition and no back pressure condition. A maximum pressure head of 2240 Pa was generated at an applied voltage of 900 V by the micropump with 3D asymmetric electrode design. A maximum flow rate of 0.127 mL/min was achieved by the micropump with planar asymmetric electrode configurations. This is five times higher than the maximum flow rate generated by the micropump with the planar symmetric electrode design. / Thesis / Master of Science (MS)

Public Space for the Privatised individual

Kaulaskar, Ameya Lokesh 01 July 2022 (has links)
The spaces of the of the future are ones that take the fourth plane of space making(digital) into account. This is built with a symbiotic relationship with the other three. Throughout history, the public spaces have been a medium to open utilities and tools that were meant only for the affluent. The newspaper democratized the access to information and thus giving rise to the spatial typology of café. The fountains of Europe were a great platform for public to gather and for young artist. These were spaces of public discourse. With the wide spread of internet, the online space became a platform for public discourse. People could share their thoughts and ideas across boundaries and build a global public sphere. This change was accelerated by pandemic, by people showing support and solidarity everyone. The whole world came together on the digital spaces as a single public space as a place. They gathered to show support and to also arrange to social events. The pandemic extended limits of the public space. The project looks at incorporating this evolution of public space and expanding the discourse of public space into the physical world. The project looks at developing a public sphere for the city of Washington DC. The strategy is to leverage the attributes of physical and digital spaces to build a better public sphere. The physical spaces bring people together in spaces to confront and exchange value with civility and the digital spaces reach out to the public beyond physical and social boundaries. They physical strategy is set of Urban furniture that forms a network of spaces throughout the city. This urban furniture can be designed and made locally or can be sourced. The furniture offers a set of various experiences as chosen by the host. The host will be an individual person or a community entity. The digital strategy is an application that works as a platform for social events. But these events can be conducted by anyone, and they can control that who can get notified about it. The notification is based on your distance from the event. This will cater to hyper local and city-wide events. The platform can also be used by citizens to exhibit their talents and open it up to the public. The public and private institutions can volunteer their space for these purposes. The application and the public space do not concentrate the use and access the use of information and physical events to a singe person or entity. It distributes the power and responsibility in between all stakeholders of the public sphere. Thus, creating a robust public sphere for the fully functioning Democracy. The Research aims at expanding the discourse on public sphere and public space design. It also introduces the data for public design. The application helps citizens to review their experience of the physical experience of the public space. This data becomes the bedrock for urban designers to design and develop public space for the city. / Master of Science / The project looks at developing a public sphere for the city of Washington DC.
