The movement of the males in some species of birds during the courtship determines the probability to be chosen by the female for mating. In order to analyze the behaviors of the birds, biologists nowadays perform a manual annotation of videos displaying the courtship phase. This a tedious and time consuming task. Thus, there is a strong interest in the development of algorithms able to automat...

introduction: genital system is important herd in animal's creation. it is necessary for animal reproduction. mammal has two sex in genital system such as male and female in separated animals. animal reproduction destroyed by disorder of genital system. in this case, animals cannot produce an animal similar to them. finally it cause overthrow a species of animals. methods: histomorphologic...

This paper studies the notion of ability and its relation with the notion of action in a multi-agent context. It introduces the distinction between two notions respectively called “theoretical ability” and “ability”. The main contribution of this paper is a model of these notions in the Situation Calculus.

introduction: the present study aimed to assess the efficacy of use of combined cognitive interventions to prepare the child and parent, and distraction of child’s attention on reported intensity of pain, distress caused by lumbar puncture, and situation-related quality of life of children with cancer. method : this was a clinical trial using pretest-posttest method and a control group. study...

optimization of the exploitation operation is one of the most important issues facing the mining engineers. since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. the aim of this optimization is to maximize the net present value (npv). since the objective function of this problem is non-linear, three methods can b...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

Context: While project management success factors have long been established via the golden triangle, little is known about how project iteration objectives and critical decisions relate to these success factors. It seems logical that teams’ iteration objectives would reflect project management success factors, but this may not always be the case. If not, how are teams’ objectives for iteration...

Genes and their expression levels in individual species can structure whole communities and affect ecosystem processes. Although much has been written about community and ecosystem phenotypes with a few model systems, such as poplar and goldenrod, here we explore the potential application of a community genetics approach with systems involving invasive species, climate change and pollution. We ...
