Many wave energy devices are currently studied. In this thesis we focus on two specific devices: the Oscillating Water Column (OWC), and the buoys. In the first part of this thesis we examine the effects of coastline geometry on the performance of an OWC. Under the assumption of inviscid irrotationnal flow, we develop a linear theory for the velocity potential for the case of a coastline of arbitrary apex angle. Scattering and radiation problems are solved separately using eigenfunctions expansions, and are then combined to study the energy extraction rate. Numerical simulations for a convex and a concave corner are considered and comparison with an OWC at the tip of a thin breakwater and on a straight coast are discussed. Assuming that the multiple-turbine system can be controlled over a wide range of frequencies, we study the effects of fixed chamber size and air compressibility on the optimal power extraction. A simpler way of optimization is then develop and we show that this simpler scheme can achieve almost as high an efficiency as the idealized many-frequency optimization. In the second part of this thesis, we first model theoretically an array of cylinders and then apply the theory developped to an array of buoys. However, numerical difficulties encountered for the array of cylinders have led to the conclusion that the theory developed is numerically inefficient, although it is accurate.

In the wake of contemporary widespread fare simplification in many major airline markets, this thesis is concerned with the possibilities and the potential for airline revenue management in less-differentiated fare environments. Traditional revenue management has relied upon the assumption that independent demands exist for different fare class products, and can be forecast as such. However, in less-differentiated fare environments this assumption has been shown to lead to "spiral-down" in revenues. Hence, in this thesis, seat inventory control methods are simulated in less-differentiated fare environments and their relative performances are compared. The methods tested are: EMSRb-based Fare Class Yield Management (FCYM); Heuristic Bid Price (HBP); Displacement Adjusted Virtual Nesting (DAVN); and Probabilistic Bid Price (ProBP). Each of the methods is tested in conjunction with two different demand forecasting philosophies: the traditional pickup (or moving average) forecaster which is based on the assumption of independent demands; and a hybrid forecasting method based on the notion that there is one demand for flexible products and another demand for the cheapest product. The methods are simulated in two different competitive airline network environments: a symmetric network with simplified fares; and a more complex non-symmetric network with mixed fare structures. Simulation shows that the performance of all four revenue management methods suffers in less-differentiated fare environments if they continue to use traditional forecasting. Methods that forecast demand at the path level see inflated forecasts for more expensive products, leading them to reject too much lower-class demand; methods that forecast demand at the leg level see diminished forecasts for the more expensive products, leading them to accept too much lower-class demand. The efficacy of FCYM improves in less-differentiated fare environments, providing a gain of about 19% over "First Come First Served" revenues (as compared to the 6% gains seen previously), nevertheless, fare product simplification still results in overall network revenue losses of around 16%. Incremental gains from O-D control when using traditional forecasting range from 0.44% to 1.93%.o over FCYM. In contrast, when the new hybrid forecaster is used, revenue management performance improves significantly, and all methods provide larger revenue gains in all competitive network environments. Revenues under FCYM are now 1.7-2.6% higher than when traditional forecasting is used. When using hybrid forecasting, the incremental gains from O-D control now range from 2.6% to 4% over FCYM.

Singapore's Active, Beautiful, and Clean Waters Programme (ABC) aims to provide functional use of its water bodies to the public. The Kallang River Basin, being part of the ABC Programme, will be used for recreational purposes such as dragon boating and other water sports. In order to provide safe recreational use for the public, the water quality of the Kallang River Basin needed to be determined and modeled. The water quality indicator chosen to be analyzed was Escherichia coli (E. coli) bacteria. A heuristic study was performed in order to determine the water quality and as well determine if water quality modeling was feasible for the Kallang River Basin. The study employed the United States Environmental Protection Agency WASP (Water Quality Analysis Simulation Program) model. Through WASP model simulations, it was found that certain parts of the Kallang River Basin were not suitable for recreational purposes and others parts were deemed suitable. E. coli concentrations predicted by the model were within the range of actual field data but diurnal variations were not captured by the model for lack of data with which to specify diurnally varying inputs. The WASP model created by this study suggests that water quality modeling for the Kallang River Basin is feasible but there are modifications that need to be made to accurately capture diurnal variations experienced by the Kallang River Basin. Future investigation into the diurnal variations would contribute to creating a more complete and accurate model for the Kallang River Basin.

Dengue is the most prevalent human arboviral disease in the world with an estimate of 390 million cases per year. The disease is mainly transmitted by two mosquitoes: Aedes aegypti and Ae. albopictus. Despite the continuous efforts to curb the spread of the disease in Singapore, there is an upsurge in dengue epidemics. In this thesis, the role of Aedes mosquitoes in shaping the spatiotemporal patterns of dengue transmission in Singapore is investigated. Field surveys are carried out to study the effect of monsoons on the disease vectors; the impact of urban housing on spatial patterns of dengue transmission is explored; and mechanistic models are developed to simulate the seasonality of dengue occurrence in the city. The role of monsoons in shaping the seasonal pattern of dengue is investigated. Singapore has no pronounced dry season, while dengue cases decrease every year after a very wet monsoon. A preliminary survey documents that Aedes mosquitoes breed in drains close to houses. A hypothesis that the very wet monsoon results in a strong reduction of outdoor breeding of Aedes is tested using field data. A one-year entomological survey confirms the hypothesis and shows that a monsoonal sequence of flushing-drying conditions in the drains shapes the seasonal abundance of Aedes in Singapore. This finding can be used to optimize vector control efforts and to better understand dengue transmission in the context of climate change. The influence of urban housing on the distribution of dengue at neighborhood and country scales is studied. Dengue incidence, vector abundance, and drainage network density are found to be higher in a subarea of low-rise housing in Geylang. Further, a holistic analysis at the country-scale confirms the role of urban housing in shaping spatial patterns of dengue. Dengue incidence is found to be proportional to the fraction of the area (or population) of low-rise housing. This finding suggests that affording public housing in agglomerations of high-rise buildings would have a positive impact on dengue control if this urban housing develops at the expense of low-rise areas. A mechanistic model is developed to investigate the role of drainage networks in the outdoor breeding of Aedes and transmission of dengue virus. The HYDRology, Entomology and DEngue Transmission Simulator (HYDREDETS) consists of three coupled dynamic models, with an explicit representation of the spatial domain. The model is calibrated using field observations to study rainfall-effects on flushing/drying of aquatic stages and re-inoculation by dormant eggs. Dengue vertical transmission and the role of human movements are incorporated in the model. HYDREDETS is capable of simulating patterns of dengue transmission in Singapore, however with reduced seasonality. This finding supports the hypothesis that dengue seasonality in Singapore can be attributed to a significant degree, to flushing-drying sequence in outdoor breeding habitats. Based on the conclusions of this thesis, spatiotemporal patterns of dengue in Singapore are shaped by climate and urban ecology which influence the ecology of Ae. aegypti and Ae. albopictus. HYDREDETS is a new modeling tool tailored to the study of vector-borne diseases related to urban hydrology. Dengue vector control can be optimized using these new tools and the improved understanding of the disease ecology.

Malaria transmission in West Africa is closely tied to climate, as rain fed water pools provide breeding habitat for the anopheles mosquito vector, and temperature affects the mosquito's ability to spread disease. This thesis presents a framework of highly detailed, spatially explicit mechanistic modelling to explore the relationships between the environment and malaria in the current and future climate of West Africa. A mechanistic model of human immunity was incorporated into an existing agent-based model of malaria transmission, allowing us to move beyond entomological measures such as mosquito density and vectorial capacity to analyzing the prevalence of the malaria parasite within human populations. The result is a novel modelling tool that mechanistically simulates all of the key processes linking environment to malaria transmission. Simulations were conducted across climate zones in West Africa, linking temperature and rainfall to entomological and epidemiological variables with a focus on nonlinearities due to threshold effects and interannual variability. Comparisons to observations from the region confirmed that the model provides a reasonable representation of the entomological and epidemiological conditions in this region. While current generation climate models agree that mean temperatures in West Africa will likely increase by 2 to 4° C in the future by the end of the 21st century, they disagree on the magnitude and the direction of the change in rainfall. We analyzed the performance of CMIP5 climate models in simulating West African rainfall and temperature before selecting the most credible predictions of future climate. We used these predictions to simulate the expected change in malaria transmission in sensitive regions of West Africa. We found that the western subregion of West Africa is likely to become drier in the coming decades. The warmer temperatures will shorten mosquito life spans, and the drying will limit mosquito reproduction. As a result, we expect malaria transmission in this region to decrease. However, the eastern half of the region is expected to become wetter. In some areas, the positive effects of increased rainfall on mosquito reproduction may surpass the negative effects of high temperatures on mosquito longevity, leading to a small net increase in environmental suitability for malaria transmission.

Повний текст джерелаTiriamoji problema. Šiandieniniame gyvenime, mechanizavus pramonės ir žemės ūkio gamybą, didėjant transporto srautams miestuose ir gyvenvietėse, modernėjant buitinei technikai, sparčiai plečiasi padidinto triukšmo zonos. Medikai teigia, kad triukšmas mažina organizmo imuninį atsparumą ir įspėja, kad triukšmas, kaip lėtinis streso šaltinis, veikia centrinę nervų sistemą ir kelia įvairių sveikatos sutrikimų. Net palyginus nestiprus 60 – 70 dB triukšmas kelia galvos skausmus, nemigą, pablogėja atmintis, dėmesys, darbingumas. Stacionarių šaltinių skleidžiamas triukšmas sumažinamas keičiant detales keičiant, padengiant įrenginių paviršių guma, plastmase ir kt. Jeigu neįmanoma sumažinti triukšmo ten, kur jis kyla, įrengiami gaubtai, izoliuojamos patalpos, bei taikomos garsą slopinančios sistemos (triukšmą mažinantys barjerai, tūriniai garso sugėrikliai, sienos dengiamos garsą izoliuojančia medžiaga). Transporto keliamo triukšmą sklaidą mažina triukšmo slopinimo sienelės, želdiniai, pastatai. Taip pat veiksmingi būdai yra transporto greičio apribojimas, kelių dangos paviršiaus keitimas, eismo ribojimas ir reguliavimas. Inžineriniai sprendimai būna pigesni, jei įvertinami architektūrinio planavimo stadijoje. Nagrinėjant triukšmo mažinimo priemonių bei metodų įgyvendinimo galimybę, ypač svarbus skaitinis triukšmo sklaidos modeliavimas. Darbo aktualumas. Įvairūs technologiniai procesai kelia triukšmą.
