A source-extraction based coupling method for computational aeroacoustics
… generated sound using a source-extraction based coupling approach. In the present coupling method, the unsteady aerodynamic calculation and the calculation of sound propagation are separated artificially. A set of acoustic perturbation equations is derived by decomposing all flow variables into …

Multi-Time-Step Domain Decomposition and Coupling Methods for Non-Linear Structural Dynamics
The present multi-time-step coupling method is based on a dual Schur domain decomposition method that uses Lagrange multipliers to enforce the continuity of the solution across the interfaces between the subdomains. The subdomains can be integrated with different time steps and/or time stepping …

Spatial and temporal coupling models for the discovery of binding events in ChIP-Seq data
In this thesis, we will present two methods for identifying binding events in ChIP-Seq data. The motivation of this venture is to propose a complete read generating process under a probabilistic graphical model framework which will determine more accurately binding event locations and enforce …

Stabilized Finite Elements and a Domain Decomposition Method for First-Order Transient Problems
In the third part, a novel domain decomposition method for first-order transient nonlinear problems is presented. To the author's knowledge the proposed method is the only known robust domain decomposition method for transient problems that enables arbitrary numeric schemes to be coupled with …

Expansion of the iterative cross-coupling synthesis strategy through Csp3 halide cross-coupling, Mida boronate synthesis, and chan-lam couplings
The iterative cross-coupling strategy for small molecule synthesis has been shown to be a powerful and effective method for the synthesis of small molecules. However, this strategy was limited by current methodological limitations. Therefore, we have extended the power and application of the …

The development of iterative and cascade methods for the rapid synthesis of ladder polyether natural products
I. The Development of Methods for the Iterative Synthesis of Polytetrahydropyrans An iterative method comprising chain homologation, epoxidation, 6-endo cyclization, and protiodesilylation was developed. Notable achievements include the development of a novel propargyl organocopper coupling method, …

Evaluation of optical solder for fiber-to-waveguide coupling in silicon photonics
… The latest issue was addressed in this work. Coupling light efficiently from fiber to waveguide is challenging because of the size (6[mu]m core diameter for fiber, 500nm for waveguide), shape, and refractive index (~1.5 for fiber, 3.5 for waveguide) differences. Optical solder was proposed as …
