Ultrasound-modulated optical tomography is modeled by a linear integral equation and an inverse problem involving a diffusion equation in n spatial dimensions, n=2, 3. Based on measured data, the optical absorption coefficient μ is reconstructed inside of a given domain. We make a two-step mathematical model. First, we solve a linear integral equation. Assuming the energy fluence rate has been recovered from the previous equation, the absorption coefficient μ is then reconstructed by solving an inverse problem. Numerical experiments are presented for the case n=2. Two methods are used for the numerical experiments, gradient descent and levelset. At the end, advantages and disadvantages of those two methods are mentioned.

There are significant gaps in research on gambling and problem gambling among people of African descent in Canada. In this qualitative research the author sought to explore the experiences and perceptions of African Nova Scotians who self-identify as “problem gamblers”, individuals who have been impacted by family members with gambling problems and African Nova Scotian community members. The author also examined the structural and cultural factors that influence help-seeking for African Nova Scotians with gambling problems. The results of the research revealed that problem gambling impacts individuals, family members and the African Nova Scotian community as a whole. African Nova Scotians’ perceptions of gambling, problem gambling and available treatment services prevented service accessibility for gambling related problems. Cultural and structural factors also prevented help-seeking among African Nova Scotians with gambling related problems, hence the underrepresentation of African Nova Scotians in treatment services. / This thesis focuses on the impact of problem gambling on African Nova Scotians and the factors that influence treatment accessibility for gambling related problems.

The main objective of the present work is to investigate the nature of the cognitive processes responsible for the problem-solving operations of novices, intermediates, and experts in a semantically rich and complex domain, i.e. electronics trouble shooting, in relation to their knowledge of the task. The performance for each group of subjects shows a varying degree of knowledge integration (theoretical and procedural). The results show (1) that novices lack theoretical knowledge and make theoretical errors, (2) that intermediates do not lack theoretical knowledge but they have some difficulty in applying it, and (3) that experts have well-integrated knowledge and troubleshooting procedures for circuits and that they are able to apply procedures and correctly interpret the results to identify the reasons for failure in the circuits. Expertise in troubleshooting circuits is an ability to adaptively apply debugging procedures and interpret the results in terms of a mental model of the circuit's behavior and structure.
