In this thesis, we asymptotically construct steady-state localized spot solutions to the Brusselator reaction-diffusion system in the semi-strong interaction regime characterized by an asymptotically large diffusivity ratio. We consider two distinct settings: a periodic pattern of localized spots in R2 concentrating at lattice points of a Bravais lattice, and multi-spot solutions that concentra...

PURPOSE Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are similar genetic disorders whose patterns of mutation and disease phenotypes might be expected to show differences among different countries. We analyzed multiplex ligation-dependent probe amplification (MLPA) data in a large number of Korean patients with DMD/BMD. MATERIALS AND METHODS We obtained 130 positive M...

This work presents a method to control the perceived distance of an auditory object by changing the directivity pattern of a loudspeaker and consequently the direct-to-reverberant ratio at the listening spot. Control of the directivity pattern is achieved by beamforming using a compact multi-driver loudspeaker unit. A small-sized cubic array consisting of six drivers is assembled, and per drive...

Polymer and surfactant (S/P) binary flooding is a widely used chemical technology for enhanced oil recovery (EOR). However, it mostly in the five-spot well pattern, there little research on effect of patterns its flow law EOR efficiency reservoir. In this paper, intensity S/P an inverted seven-spot unit are investigated. Based theoretical derivation simulation, distribution at different positio...

Health monitoring of structural joints is a major concern of the engineering community. Among joining techniques, spotwelding play a major role. Spot welding is the traditional method of assembly for steel-based automotive structures, while spot-welding of aluminum is being considered for future vehicular structures. Though spot welding of steel is well researched and understood, the spot-weldi...

Abstract This paper presents an approach to optimize the recovery factor and sweep efficiency in a waterflooding process by automating optimum injection rate calculations for water injectors using streamline simulation. A simulator is appropriate tool modern waterflood management can be used determine dynamic interaction between injector producer pairs, which will vary over time based on operat...
