34 p, 631.7 KB Do labor market institutions matter for business cycles? / Gnocchi, Stefano (Bank of Canada) ; Lagerborg, Andresa (European University Institute (Itàlia)) ; Pappa, Evi (Universitat Autònoma de Barcelona)
Using panel data of 19 OECD countries observed over 40 years and data on specific labor market reform episodes we conclude that labor market institutions matter for business cycle fluctuations. Spearman partial rank correlations reveal that more flexible institutions are associated with lower business cycle volatility. [...]

28 p, 700.0 KB Using robust FPCA to identify outliers in functional time series, with applications to the electricity market / Vilar, Juan M. (Universidade da Coruña. Departamento de Matemáticas) ; Raña, Paula (Universidade da Coruña. Departamento de Matemáticas) ; Aneiros, Germán (Universidade da Coruña. Departamento de Matemáticas)
This study proposes two methods for detecting outliers in functional time series. Both methods take dependence in the data into account and are based on robust functional principal component analysis. [...]

12 p, 1.3 MB A Colour Iris Recognition System Employing Multiple Classifier Techniques / Radu, Petru (University of Kent. School of Engineering and Digital Arts) ; Sirlantzis, Konstantinos (University of Kent. School of Engineering and Digital Arts) ; Howells, Gareth (University of Kent. School of Engineering and Digital Arts) ; Hoque, Sanaul (University of Kent. School of Engineering and Digital Arts) ; Deravi, Farzin (University of Kent. School of Engineering and Digital Arts)
The randomness of iris texture has allowed researchers to develop biometric systems with almost flawless accuracies. However, a common drawback of the majority of existing iris recognition systems is the constrained environment in which the user is enroled and recognized. [...]

10 p, 548.4 KB Implementation of Max Principle with PCA in Image Fusion for Surveillance and Navigation Application / Sadhasivam, Senthil Kumar (St. Joseph's College of Engineering. Department of Electronics and Communication Engineering) ; Keerthivasan, Mahesh Bharath (University of Arizona. Department of Electrical and Computer Engineering) ; Muttan, S. (Anna University (Chennai, India). Department of Electronics and Communication Engineering)
Image fusion is the combination of two or more different images by using suitable algorithms to form an output image. It provides a useful tool to integrate multiple images into a composite image. In this paper, we present an approach that uses the principle component analysis (PCA) along with the selection of maximum pixel intensity to perform fusion. [...]

16 p, 381.9 KB Spatial and temporal heterogeneity in the Alqueva reservoir, Guadiana river, Portugal / Serafim, António ; Morais, Manuela ; Guilherme, Pedro ; Sarmento, Paula ; Ruivo, Manuela ; Magriço, Ana
This study aims to assess the physico-chemical variability of the Alqueva reservoir during its initial filling period. The dataset consists of analytical results from an 11 month survey (Mar 2003-Jan 2004) conducted in the water body, at three levels of depth in the several tributaries and in the discharge section. [...]
Este estudio apunta a determinar la variabilidad fisco-química del embalse de Alqueva en su período de llenado inicial. El conjunto de datos consiste en resultados analíticos a partir de los primeros once meses de muestreo (marzo de 2003-enero de 2004) conducida en el cuerpo del agua, en tres niveles de profundidad; en los varios tributarios y en la sección de la descarga.

13 p, 404.8 KB An Experimental Investigation about the Integration of Facial Dynamics in Video-Based Face Recognition / Hadid, Abdenour (University of Oulu (Finlàndia). Department of Electrical and Information Engineering) ; Pietikäinen, Matti (University of Oulu (Finlàndia). Department of Electrical and Information Engineering)
Recent psychological and neural studies indicate that when people talk their changing facial expressions and head movements provide a dynamic cue for recognition. Therefore, both fixed facial features and dynamic personal characteristics are used in the human visual system (HVS) to recognize faces. [...]
