This thesis investigates the use of micro-injection moulding (μIM), as a high-volume process, for producing three-dimensional, integrated microfluidic devices. It started with literature reviews that covered three topics: μIM of thermoplastic microfluidics, designing for three-dimensional (3-D) microfluidics and functional integration in μIM. Research gaps were identified: Designing 3-D microfluidics within the limitations of μIM, process optimisation and the integration of functional elements. A process chain was presented to fabricate a three-dimensional microfluidic device for medical appli

It is not uncommon to read about hacker attacks in the newspaper today. The hackers are targeting governments and enterprises, and motives vary. It may be political or economic reasons, or just to gain reputation. News about smaller systems is, unsurprisingly, not as common. Does this mean that security is less relevant of smaller systems? This report investigates the threat model of smaller web applications, to answer that very question.Different attacks are described in the detail needed for explaining their threat but the intention is not to teach the reader to write secure code.

Large quantities of oil usually remain in oil reservoirs after conventional water floods. A significant part of this remaining oil can still be economically recovered by Water- Alternating-Gas (WAG) injection. WAG injection involves drainage and imbibition processes taking place sequentially, hence the numerical simulation of the WAG process requires reliable knowledge of three-phase relative permeability (kr) accounting for cyclic hysteresis effects. In this study, the results of a series of unsteady-state two-phase displacements and WAG coreflood experiments were employed to investigate the

An analysis was performed of a Texas gulf coast hazardous waste injection well disposal system. The system was complicated by the presence of a fault which transected the injection interval. The existence of the fault presented the potential for enhanced vertical migration of the injected solutes via a tortuous path of interconnected, highly permeable sand units. Evaluation of this potential necessitated a fully three dimensional model which incorporated the arrangement of the alternating shales and sands and their associated discontinuities.

An estimated 30% of the faults in Induction Machine (IM) are related to its stator. These faults are mostly in the form of an Inter-Turn Short Circuit (ITSC) fault i.e., when two winding inside the stator of IM are shorted due to insulation failure. However, ITSC fault can be avoided by detecting them in advance and then scheduling the maintenance of the IM. This thesis studies two methods for detecting this incipient ITSC fault in a three-phase IM and then estimating the stator resistance unbalance due to the ITSC fault. The first method is based on the asymmetry caused in the IM by the ITSC

Flow structures in turbulent flows span many orders of magnitude of length and time scales. They range from the length scale at which very small eddies lose their coherence as their translational kinetic energy is dissipated into heat, up to eddies the size of which is related to that of the macroscopic system. The behaviour of the range of flow structures can be captured by assuming that the fluid is a continuum, and they can be described by solving the Navier-Stokes equations. However, analytical solutions of the Navier-Stokes equations exist only for simple cases. A complete description of

碩士<br>國立成功大學<br>電機工程學系<br>102<br>This thesis presents design and implementation of the single-switch three-phase wind power converter with harmonic injection mechanism. In order to obtain optimal output power of the wind turbine generator (WTG) at different wind speeds, a maximum-power-point-tracking (MPPT) mechanism is required. Furthermore, to improve the input power-factor of the wind energy conversion system (WECS), the conventional single-switch three-phase boost rectifier is employed. However, the input current of the conventional single-switch boost rectifier exhibits a relatively large

Degassing and in situ formation of a mobile gas phase takes place when an aqueous phase equilibrated with a gas at a pressure higher than the subsurface pressure is injected in water-saturated porous media. This process, which has been termed supersaturated water injection (SWI), is a novel and hitherto unexplored means of introducing a gas phase into the subsurface. Herein is a first macroscopic account of the SWI process on the basis of continuum scale simulations and column experiments with CO2 as the dissolved gas. A published empirical mass transfer correlation (Nambi and Powers, Water

碩士<br>中原大學<br>機械工程研究所<br>91<br>Gas-assisted injection molding is an innovative molding process. Although GAIM can greatly improve product quality, it is difficult to control gas penetration in a desired way. Therefore, mold designers must try and error repeatedly in order to obtain optimal processing conditions. Commercial CAE software can offer solutions to design products better and economically. But gas penetration characteristics are not appeared in 2.5D simulation, so 3D real elements are necessary to be used in simulation of gas-assisted injection molding. In this research, we study gas

The control method can realize rectification and low current total harmonic distortion (THD), which can make converter operate with power factor correction (PFC)mode, PF leading mode, PF lagging mode and achieve two loads output power balance or unbalance. This control method can enhance converter ability and make it more flexible to application. Furthermore, the reactive power and capacitor voltage balance controls operatio

Chemical treatments using solvents and surfactants can be used to increase the productivity of gas-condensate wells with condensate banks. CMG’s compositional simulator GEM was used to simulate such treatments to gain a better understanding of design questions such as how much treatment solution to inject and to predict the benefits of such treatments. GEM was used to simulate treatments in vertical wells with and without hydraulic fractures and also horizontal wells. However, like other commercial compositional simulators, the flash calculations used to predict the phase behavior is limited t

Despite increased involvement in the criminal justice system among populations of migrants, people who inject drugs, and drug-involved men in community corrections, few studies investigate associations between involvement in the criminal justice system and sexual and injection drug risks among these key-affected populations and their intimate partners.
