Optimizing the collections process in consumer credit
No full textThis paper builds a dynamic programming model to optimize the collections process in consumer credit. It determines which collections actions should be undertaken and how long they should be performed. Theoretical results about the form of the optimal policy under certain conditions are obtained. Finally a case study is described based on data from the collection department of a European ban

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Tensor Coding For Cdma-mimo Wireless Communication Systems
No full textIn this paper, we propose a tridimensional tensor coding for multiple-inputmultiple-output (MIMO) communication systems. This coding allows spreading and multiplexing the transmitted symbols in both space and time domains, owing the use of two allocation matrices. Assuming flat Rayleigh fading channels, the signals received by K receive antennas during P time blocks, composed of N symbol periods each, with J chips per symbol, forma fourth-order tensor that satisfies a new constrained tensor model. A two-step alternating least squares (ALS) algorithm is proposed for blindly and jointly estimating the channel and the transmitted symbols. The performance of the proposed blind receiver is evaluated by means of computer simulations. © EURASIP, 2011.101105De Almeida, A.L.F., Favier, G., Mota, J.C.M., A constrained factor decomposition with application to mimo antenna systems (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2429-2442De Almeida, A.L.F., Favier, G., Mota, J.C.M., Constrained tensor modeling approach to blind multipleantenna cdma schemes (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2417-2428De Almeida, A.L.F., Favier, G., Mota, J.C.M., Multiuser mimo system using block space-time spreading and tensor modeling (2008) Signal Processing, 88 (10), pp. 2388-2402De Almeida, A.L.F., Favier, G., Mota, J.C.M., Space-time spreading-multiplexing for mimo wireless communication systems using the paratuck-2 tensor model (2009) Signal Processing, 89 (11), pp. 2103-2116De Baynast, A., De Lathauwer, L., Aazhang, B., Blind parafac receivers for multiple access-multiple antenna systems (2003) Proc.

Instituto de Investigaciones Biológicas y Tecnológicas; Argentina.Culex quinquefasciatus (Diptera: Culicidae) es el principal vector de la Encefalitis de San
Luis (ESL) en nuestro país, representando un serio problema en salud pública. En los últimos
años se han registrado casos de ESL en la Ciudad de Córdoba, destacándose el brote ocurrido
en el año 2005. Debido a esto, resulta importante poder realizar pronósticos referidos a las
fechas de ocurrencia de mínimos y máximos de abundancia de este mosquito, información útil
para controlarlo y prevenir la enfermedad. En este trabajo se propone la aplicación de un
modelo matricial a tiempo discreto para simular la fluctuación temporal de la abundancia de Cx.
