Inference for Generalized Linear Models via Alternating Directions and Bethe Free Energy Minimization

Ulugbek Kamilov

Generalized Linear Models (GLMs), where a random vector x is observed through a noisy, possibly nonlinear, function of a linear transform z = A x arise in a range of applications in nonlinear filtering and regression. Approximate Message Passing (AMP) meth ...

The visible perimeter of an arrangement of disks

János Pach, Gabriel Nivasch

Given a collection of n opaque unit disks in the plane, we want to find a stacking order for them that maximizes their visible perimeter, the total length of all pieces of their boundaries visible from above. We prove that if the centers of the disks form ...

A Wearable System for Multi-Segment Foot Kinetics Measurement

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

This study aims to design a wearable system for kinetics measurement of multi-segment foot joints in long-distance walking and to investigate its suitability for clinical evaluations. The wearable system consisted of inertial sensors (3D gyroscopes and 3D ...

Analytical approximation for the recession of a sloping aquifer

David Andrew Barry, Marc Parlange

An approximation is obtained for the recession of a sloping aquifer. The analytical approximation can provide a useful tool to analyze data and obtain physical properties of the aquifer. In contrast to the case of a horizontal aquifer, when plotting the ti ...

Iso-level tool path planning for free-form surfaces

Bailin Deng

The aim of tool path planning is to maximize the efficiency against some given precision criteria. In practice, scallop height should be kept constant to avoid unnecessary cutting, while the tool path should be smooth enough to maintain a high feed rate. H ...

Theoretical and experimental study of the bending influence on the capacitance of interdigitated micro-electrodes patterned on flexible substrates

Nico de Rooij, Danick Briand, Francisco Molina Lopez

Interdigitated electrodes are common structures in the fields of microelectronics and MEMS. Recent developments in flexible electronics compel an understanding of such structures under bending constraints. In this work, the behavior of interdigitated micro ...

Randomized Extended Kaczmarz For Solving Least Squares

Nikolaos Freris

We present a randomized iterative algorithm that exponentially converges in the mean square to the minimum l(2)-norm least squares solution of a given linear system of equations. The expected number of arithmetic operations required to obtain an estimate o ...

Application of Artificial Vision to the Quality Inspection of Surfaces of Luxury Products

Giuseppe Zamuner

This thesis defines a general approach for the automated visual inspection of surfaces of luxury products, the aesthetic quality of which represents a corollary to the technical mastery necessary to manufacture valuable products. Within a manufacturing ent ...
