Spatial Coupling for High-Dimensional Estimation
… performance. This thesis investi- gates spatial coupling, a design technique that can enhance reconstruction performance with efficient algorithms for a variety of inference problems. For many high-dimensional regression models with unstructured designs, the Bayes-optimal estimator is …

Homogenization Methods for Problems with Multiphysics, Temporal and Spatial Coupling
… of the case of full nonlinear electromechanical coupling with large deformations, which allows simulating effectively behavior of electroactive materials such as composites made of electroactive polymers. Secondly, homogenization was extended on wave problems where dispersion is significant and …

Spatial and temporal coupling models for the discovery of binding events in ChIP-Seq data
… we will first propose the so-called Spatial Coupling method which exploits the relative positions of reads by assuming dependent assignment of events to close reads. Second, we will present the so-called Temporal Coupling method, whose goal is to align events across multiple …

Spatially Coupled Sparse Regression Codes for Single- and Multi-user Communications
… columns. Techniques such as power allocation and spatial coupling have been proposed to improve the performance of low-complexity iterative decoding algorithms such as approximate message passing (AMP). In this thesis we investigate spatially coupled SPARCs, where the design matrix has a block- …

An efficient method for the solution of the energy dependent integral Boltzmann transport equation in the resolved resonance energy region
… A very efficient multigroup solution of the two spatial region energy dependent integral transport equation is developed. This solution, denoted the "Broad Group Integral Method'' (BGIM), uses escape probabilities to obtain the spatial coupling between regions and uses an analytical flux shape …

Modeling of frame structures undergoing large deformations and large rotations
… is the formulation of a geometrically consistent coupling of beams and continuum elements, especially in the presence of large deformations and large rotations. In addition to spatial coupling of beam and continuum elements, a multi-time-step method is also formulated to allow the beam and …

Stochastic Geometry for Vehicular Networks
… communication networks. However, the canonical spatial models such as the 2D Poisson point process (PPP) does not capture the peculiar spatial layout of vehicular networks, where the locations of vehicular nodes are restricted to roadways. Motivated by this, we consider a doubly stochastic …

Advances in Stochastic Geometry for Cellular Networks
… the common practice is to assume complete spatial randomness} of the network topology. In other words, the locations of users and BSs are modeled as independent homogeneous Poisson point processes (PPPs). Despite its usefulness, the PPP-based network models fail to capture any spatial …
