Statistical Inference for Partially Observed Stochastic Epidemics

Andrea Kraus

This work is concerned with the estimation of the spreading potential of the disease in the initial stages of an epidemic. A speedy and accurate estimation is important for determining whether or not interventions are necessary to prevent a major outbreak. ...

Rating the performance of a Brillouin distributed fiber sensor

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The effect of the characteristics of a generic distributed fiber sensor based on stimulated Brillouin scattering on the amplitude of the response is analyzed and a relation between the measurement noise on the time traces and the error on the determination ...

Accurate Internal-External Rotation Measurement in Total Knee Prostheses: a magnetic solution

Kamiar Aminian, Jenifer Cléa Miehlbradt, Arash Arami

In this work we tackled the problem of accurate measurement of internal–external (IE) rotations in the prosthetic knee. We presented a magnetic measurement system to be implanted in the knee prostheses in order to measure IE without soft tissue artifacts. ...

On identification methods for direct data-driven controller tuning

Alireza Karimi, Klaske van Heusden

In non-iterative data-driven controller tuning, a set of measured input/output data of the plant is used directly to identify the optimal controller that minimizes some control criterion. This approach allows the design of fixed-order controllers, but lead ...

Using measured instead of perceived noise in hedonic models

Philippe Thalmann, Andrea Baranzini, Caroline Schaerer

This paper compares the use of perceived and measured noise in a hedonic housing model. Although in theory the use of subjective variables is recommended, most empirical applications use measured noise variables. Merging different databases, we obtain a sa ...

Undecimated Haar Thresholding For Poisson Intensity Estimation

Michaël Unser, Thierry Blu, Florian Luisier

We propose a novel algorithm for denoising Poisson-corrupted images, that performs a signal-adaptive thresholding of the undecimated Haar wavelet coefficients. A Poisson's unbiased MSE estimate is devised and adapted to arbitrary transform-domain pointwise ...

The SURE-LET approach to image denoising

Florian Luisier

Denoising is an essential step prior to any higher-level image-processing tasks such as segmentation or object tracking, because the undesirable corruption by noise is inherent to any physical acquisition device. When the measurements are performed by phot ...

Dynamic noise modeling at roundabouts

Modeling spatial and temporal noise variations at roundabouts is a tedious task. Indeed, noise levels are strongly influenced by the complex vehicle interactions taking place at the entries. An accurate modeling of the merging process and its impact on veh ...

Performance analysis of the cepstral technique for frequency-domain optical-coherence tomography

Michaël Unser

Recently, we proposed a noniterative cepstral technique for exact signal recovery in frequency-domain optical-coherence tomography. In this paper, we address the influence of measurement noise on the performance of the method. We derive analytical expressi ...
