Splitting Arabic Texts into Elementary Discourse Units

International audienceIn this article, we propose the first work that investigates the feasibility of Arabic discourse segmentation into elementary discourse units within the segmented discourse representation theory framework. We first describe our annotation scheme that defines a set of principles to guide the segmentation process. Two corpora have been annotated according to this scheme: elementary school textbooks and newspaper documents extracted from the syntactically annotated Arabic Treebank. Then, we propose a multiclass supervised learning approach that predicts nested units. Our approach uses a combination of punctuation, morphological, lexical, and shallow syntactic features. We investigate how each feature contributes to the learning process. We show that an extensive morphological analysis is crucial to achieve good results in both corpora. In addition, we show that adding chunks does not boost the performance of our system

The use of batteries in hybrid vehicles

Symposium IEEE VTS Vehicle Power and Propulsion, PARIS, FRANCE, 06-/10/2004 - 08/10/2004This paper details the main functions of hybrid drivelines according to their architecture together with the corresponding characteristics and constraints of the batteries. Battery behavior for different types of hybrid drivelines are presented through experiments conducted on the first marketed hybrid vehicles. The problem of battery ageing is accessed through battery failure modes and testing procedures. The battery depth of discharge (DoD) is highlighted as an important factor in battery ageing, if not properly controlled. Consequently a DoD evaluation method is presented. Experiments and firsts results on a VRLA battery are described

Iatrogenic neonatal bladder perforation

Neonatal bladder rupture is rare as a complication of bladder obstruction due to abnormal anatomy or iatrogenic causes. The present study describes the case of a 3-day-old infant with ascites due to bladder perforation secondary probably to manual decompression of the bladder. The infant underwent successful surgical repair of the perforation
