analysis does not test for causal relationships, only whether there is a relationship and, to some extent, the strength of this relationship. Linear regression analysis is used to predict or estimate the value of a normally distributed response variable from the known values of one or more explanatory variables which are not necessarily normally distributed. When the analysis uses a single expl...

fourteen different morphological traits in 169 and 131 cattle of oulmes-zaer and tidili, respectively were recorded and analyzed using a multivariate approach. the characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. breed signif...

in developing countries, the domination of peripheral and dependent capitalism relations and the lack of appropriate structures and channels of attracting, this system have caused some kind of spatial-anatomic unbalances that has resulted in the appearance of single cities with national and regional prevalence. this situation is the main reason for small, medium and intermediate cities to lose ...

Intestinal contractions are one of the main features for analyzing intestinal motility and detecting different gastrointestinal pathologies. In this paper we propose Eigenmotion-based Contraction Detection (ECD), a novel approach for automatic annotation of intestinal contractions of video capsule endoscopy. Our approach extracts the main motion information of a set of contraction sequences in ...

This paper addresses two issues. Firstly, because the coarse­scale model inevitably misses out sub­grid heterogeneity, physical dispersion is ignored in the simulation. Secondly, the small­scale heterogeneity is not explicitly known and can only be inferred by history­matching. To solve these problems, local features in the coarse­scale relative permeability curves were adjusted in history­matc...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...
