Increasing concerns about global warming have led to the exploration of options to abate CO2 emissions. Recent studies have identified the energy sector as the largest emitting source worldwide. Therefore, the transition towards low-carbon power systems has incorporated larger volumes of renewable generation. This situation is prompting the necessity of improving current strategies to operate power systems, as more variability is introduced in the decision making process. This thesis contributes in two aspects to manage the generation mix of future power systems. Firstly, it addresses the question of how many scenarios are enough to represent the variability of wind power. Results obtained indicate that a balance should be pursued between quality of solution and computational burden, as more scenarios does not significantly change the operational cost. Secondly, an original method to narrow down the number of scenarios is proposed. The so-called severe scenarios outperform typical reductions in the sense that fewer adjustments are required to the generation scheduling programme. Despite the growing renewable generation capacity, the operation of the electric system is likely to continue its reliance on thermal plants. Hence, the need to curb CO2 emissions in the existing thermal plants has led to the development of technologies such as carbon capture. The technical maturity of this technology is still in its early stages, since its application to thermal plants is under development. This thesis bridges the gap of current knowledge on carbon capture in three aspects. Firstly, it presents an innovative methodology to quantify the value of flexibility provided by carbon capture in the context of the British system. Secondly, the role of retrofitted generators as reserve providers is addressed. Finally, the synergy between carbon capture and wind power is assessed. The evaluation considers CO2 pricing, two strategies to manage CO2 capture rate, variability and different levels of wind integration.

This thesis examines on a conceptual level whether, in Canada, government induced centralization of the bargaining structure is apt to contribute to a stabilization of industrial relations measured in terms of a reduction in strike/lockout frequency. A micro-model of strike causation, viewing the outbreak of industrial action as the result of a deliberate gamble of the bargaining parties, forms the core of the conceptual framework developed in this paper. According to this model centralization lowers strike/lockout frequency if it (1) raises the relative costs of industrial action (2) induces the bargaining parties to integrate macro-goals into their goal portfolio (3) modifies collectivity internal interest aggregation in favor of its moderate segments and (4) successfully internalizes intra-group conflict. On the basis of theoretical considerations and existing evidence, the paper then seeks to establish whether centralization can be expected to fulfill these conditions. The study suggests that the impact of centralization upon vertical interest aggregation takes the desired direction. Because of the design of the analysis a general prediction of the effect of centralization upon horizontal interest aggregation can not be made. The relative costs of industrial action in the 'average bargaining unit' are diagnosed to remain unaffected by centralization. While centralization of the bargaining structure appears to be a necessary condition for unions and employers to integrate macro-goals into their goal portfolio, the analysis can not show that it is a sufficient condition. Finally, contingent on the readiness of the government to actively back the rule of the majority, centralization is expected to internalize intra-group conflict successfully. / Arts, Faculty of / Political Science, Department of / Graduate

El presente trabajo de investigación es una contribución intelectual para la implementación de buenas prácticas globales en gestión pública que permitan planificar, seguir y evaluar los resultados de las políticas públicas prioritarias de un país. Sobre el particular, la tendencia en el ámbito internacional, desde hace más de veinte años, ha consistido en instalar en el más nivel gubernamental delivery unit o unidades de cumplimiento que sirvan de mecanismo para el logro de objetivos prioritarios de un gobierno. En ese sentido, el documento tiene como objetivo general brindar un marco conceptual y metodológico para la implementación de un delivery unit (DU) en el gobierno peruano. Esto se podrá alcanzar mediante el cumplimiento de tres objetivos específicos que son conocer el marco conceptual de los DU, realizar un análisis situacional del marco general de las políticas públicas que resultan prioritarias para el Estado peruano, y proponer un marco metodológico para la implementación de un DU en el gobierno peruano.

The aim of this thesis is to design a clamping unit with mechanical multiplier. Unit will serve as a technological clamping element in the technical equipment. My task was to select the method of construction and design driving main unit for grip jaw. I chose a solution with a mechanical multiplier. The frame unit is made up of fixed and sliding clamping jaw and is self. Unit is designed as a built module. The entire structure must be designed to meet the initial parameters specified in the award of thesis. The main parameters include clamping strength of 80kN, the extent of working stroke 15 mm and the size of a scroll, which is 250 mm. They are also listed in the award size constraints: the length, width, height dimensions and the coupling unit.

There exist numerous commercial six-degree-ofreedom inertial measurement units capable of measuring low-range accelerations and rotation rates. A commercially available multi-range IMU capable of measuring low and high-range motions does not exist. An IMU with this capability was developed for measuring trajectory data of projectiles such as high-powered rockets. This data can be used to provide performance feedback to projectile designers and users. A small footprint printed circuit board was designed to minimize the overall size of the unit, compared to “perf-board” prototypes. Several PCB design guidelines were closely followed to reduce electrical interference in digital/analog components and traces. Embedded C code was developed to control the IMU. The unit features a wireless user interface, providing several control options, including an option to download data sampled at 1KHz per sweep of all twelve sensor channels. Preliminary testing reveals good consistency among the high and low-range sensors and acceptably low noise levels.
