28 p, 230.5 KB Multinomial logistic estimation in dual frame surveys / Molina, David (Universidad de Granada. Departamento de Estadística) ; Rueda, Maria del Mar (Universidad de Granada. Departamento de Estadística) ; Arcos, Antonio (Universidad de Granada. Departamento de Estadística) ; Ranalli, Maria Giovanna (Università di Perugia. Department of Political Sciences)
We consider estimation techniques from dual frame surveys in the case of estimation of proportions when the variable of interest has multinomial outcomes. We propose to describe the joint distribution of the class indicators by a multinomial logistic model. [...]

3 p, 2.8 MB Noise modeling and depth calibration for Time-Of-Flight cameras [Extended Abstract of Ph.D Thesis] / Belhedi, Amira
3D cameras open new perspectives in different application fields such as 3D reconstruction, Augmented Reality and video-surveillance since they provide depth information at high frame-rates. However, they have limitations that affect the accuracy of their measures. [...]

2.0 MB Evaluation of the ACR SmartButton thermometer and a low-cost protective case for continuous stream temperature measurement / Molinero, Jon ; Larrañaga, Aitor ; Pérez, Javier ; Martínez, Aingeru ; Pozo, Jesús ; Universidad del País Vasco. Departamento de Biología Vegetal y Ecología
Water temperature is a common variable of interest in stream ecology studies. In this paper, the performance of the ACR SmartButton thermometer and a low-cost protective case were evaluated for stream temperature measurement. [...]
La temperatura del agua es una variable de interés en los estudios de ecología fluvial. En este trabajo,se evalúa el rendimiento de los termómetros ACR SmartButton y de una carcasa protectora de bajo coste para la medida de la temperatura en ríos. [...]

12 p, 122.2 KB Comparing and calibrating discrepancy measures for Bayesian model selection / Horra, Julián de la ; Rodríguez Bernal, María Teresa
Different approaches have been considered in the literature for the problem of Bayesian model selection. Recently, a new method was introduced and analysed in De la Horra (2008) by minimizing the posterior expected discrepancy between the set of data and the Bayesian model, where the chi-square discrepancy was used. [...]

44 p, 465.9 KB Testing for the existence of clusters (p. 115-158) / Casella, George ; Fuentes, Claudio ; University of Florida
Detecting and determining clusters present in a certain sample has been an important concern, among researchers from different fields, for a long time. In particular, assessing whether the clusters are statistically significant, is a question that has been asked by a number of experimenters. [...]

9 p, 901.1 KB Simple fish-eye calibration method with accuracy evaluation / Hughes, Ciaran (National University of Ireland) ; Glavin, Martin (National University of Ireland) ; Jones, Edward (National University of Ireland)
In this paper, a simple fish-eye radial distortion calibration procedure is described. This method avoids costly minimisation and optimisation algorithms, and is based on trivial concentricity of three extracted points. [...]

13 p, 739.9 KB External Anatomical Shapes Reconstruction from Turntable Image Sequences using a Single off-the-shelf Camera / Azevedo, Teresa C. S. (Universidade do Porto. Faculdade de Engenharia) ; Tavares, João Manuel R. S. (Universidade do Porto. Faculdade de Engenharia) ; Vaz, Mário A. P. (Universidade do Porto. Faculdade de Engenharia)
Three-dimensional (3D) human body reconstruction and modeling from two-dimensional (2D) images is a topic of great interest and research but still remains a difficult problem to solve. Volumetric based methods are commonly used to solve this type of problem. [...]

15 p, 1.4 MB Variability of unusual distributions of alkenones in the surface waters of the Nordic seas / Bendle, James (University of Durham. Environmental Research Centre) ; Rosell Melé, Antoni (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Samples of filtered particulate organic matter (POM) were obtained during the summers of 1999 and 2000 from the surface waters of the Nordic seas to monitor the spatial distribution of long-chain alkenones. [...]

13 p, 569.2 KB A PDE Method to Segment Image Linear Objects with Application to Lens Distortion Removal / El-Melegy, Moumen T. (Assiut University (Assiut, Egipte). Electrical Engineering Department) ; Al-Ashwal, Nagi H. (Assiut University (Assiut, Egipte). Electrical Engineering Department)
In this paper, we propose a partial differential equation based method to segment image objects, which have a given parametric shape based on energy functional. The energy functional is composed of a term that detects object boundaries and a term that constrains the contour to find a shape compatible with the parametric shape. [...]
