Next-generation sequencing (NGS) technologies allow new methodologies for alternative splicing (AS) analysis. Current computational methods for AS from NGS data are mainly focused on predicting splice site junctions or de novo assembly of full-length trans...
B²IRS: A Technique to Reduce BAN-BAN Interferences in Wireless Sensor Networks
Found in: Wearable and Implantable Body Sensor Networks, International Workshop on
By Paolo Roberto Grassi,Vincenzo Rana,Ivan Beretta,Donatella Sciuto
Issue Date:May 2012
pp. 46-51
Wireless Sensor Networks (WSNs) are particular networks characterized by limited energy and computational resources and, if their transmission range is limited to a person's area, they are known as Body Area Networks (BANs). When two or more BANs are co-lo...
Model-based design for wireless body sensor network nodes
Found in: 2012 13th Latin American Test Workshop - LATW
By Ivan Beretta,Francisco Rincon,Nadia Khaled,Paolo Roberto Grassi,Vincenzo Rana,David Atienza,Donatella Sciuto
Issue Date:April 2012
pp. 1-6
Wireless body sensor networks (WBSNs) are a rising technology that allows constant and unobtrusive monitoring of the vital signals of a patient. The configuration of a WBSN node proves to be critical in order to maximize its lifetime, while meeting the pre...
Performance Evaluation of Algorithms for Newspaper Article Identification
Found in: Document Analysis and Recognition, International Conference on
By Roberto Beretta,Luigi Laura
Issue Date:September 2011
pp. 394-398
A typical modern newspaper recognition system operates in distinct phases: i) page segmentation (also called page decomposition or zoning), that is the process of decomposing a page into its structural and logical units (called regions or zones), ii) regio...
A Hybrid Mapping-Scheduling Technique for Dynamically Reconfigurable Hardware
Found in: International Conference on Field Programmable Logic and Applications
By Juan Antonio Clemente,Vincenzo Rana,Donatella Sciuto,Ivan Beretta,David Atienza
Issue Date:September 2011
pp. 177-180
Reconfigurable computing is a promising technology that offers an interesting trade-off between flexibility and performance, which many recent multi-core embedded system applications demand. In order to achieve these objectives, it is necessary to optimize...
Mining Context-Aware Preferences on Relational and Sensor Data
Found in: Database and Expert Systems Applications, International Workshop on
By Davide Beretta,Elisa Quintarelli,Emanuele Rabosio
Issue Date:September 2011
pp. 116-120
The increasing amount of available digital data motivates the development of techniques for the management of the information overload which risks to actually reduce people's knowledge instead of increasing it. Research is concentrating on topics related t...
A high-performance parallel implementation of the Chambolle algorithm
Found in: 2011 Design, Automation & Test in Europe
By A Akin,I Beretta,A A Nacci,V Rana,M D Santambrogio,D Atienza
Issue Date:March 2011
pp. 1-6
The determination of the optical flow is a central problem in image processing, as it allows to describe how an image changes over time by means of a numerical vector field. The estimation of the optical flow is however a very complex problem, which has be...
