Purpose: The goals of this study were to evaluate the use of electronic portal imaging device (EPID) paper images as off-line veri®cation tools and to assess the feasibility of replacing portal ®lms by EPID printed images. Materials and methods: Electronic portal images were acquired using a video-based imaging system. After contrast enhancement, these images were printed and compared to portal...

The automatic recognition of text on scanned images has several applications such as automatic postal mail sorting and searching in large volume of documents. Although Arabic handwritten text recognition has been addressed by many researchers, it remains a challenging task due to several factors. This paper presents an overview of off-line handwritten Arabic character recognition and summarizes...

Introduction: Nowadays applying computer in image processing is being improved revolutionary for solving medical images deficiencies. Image features that are analysis in image processing show image information. The aim of the present study was to find correlation between CT- scan and MRI images' features. Materials and Methods: After data acquisition, applying...

Rodent monitoring in biomedical laboratories is a time consuming and tedious task. Several automatic solutions that rely on different types of sensors have been proposed. Computer vision provides a significantly more universal and less intrusive solution. In this article we propose a new method to detect and classify three behaviors in rodents: Exploring, Rearing, and Static. The method uses Mo...

biotic as well as abiotic factors may influence the biocontrol activity and population density of pseudomonas fluorescens. however, limited studies have been carried out on the effects of extracellular metabolites of other competitor bacteria, especially on the biocontrol efficiency of p. fluorescens. a greenhouse experiment was conducted to evaluate the potential of the two p. fluorescens isol...

Introduction: With the advent of short-TE acquisitions, such as UTE and SWIFT, center-out radial acquisition schemes to fill k-space are gaining interest [1, 2]. Although these acquisitions minimize signal dephasing, they still suffer from field inhomogeneities through geometric distortion. Unlike for Cartesian encoding, geometric distortion for center-out radial acquisitions is directed radial...

König (1989) argues that there is a relation of duality between concessive and causal constructions. Therefore, he maintains, any account of the meaning of causal connectives like because, via duality, also provides an account of the meaning of concessive connectives such as although. This paper lists a number of problems with König's account. Appealing to notions central to relevance theory, i...

Previous experimental studies on concessive connectives have only looked at their local facilitating or predictive effect on discourse relation comprehension and have often viewed them as a class of discourse markers with similar effects. We look into the effect of two connectives, but and although, for inferring contrastive vs. concessive discourse relations to complement previous experimental...
