BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

Images taken in foggy weather condition often suffer from poor visibility and clarity. Images of the outdoor scene which are captured under bad weather conditions contain atmospheric degradation such as haze, fog, smoke caused by the particles present in the atmosphere resulting in the absorption and scattering of the light, which travels from the scene point of the observer. Due to the presenc...

We present a prototype that integrates WAP-based information access with spoken dialog interaction. WAP phone usability is encumbered by keypad entry for typing text, and also by the small screen-size that requires much scrolling during browsing or menu selection. The spoken dialog interface offers a desirable complement whereby commands may be spoken instead of typed, and the dialog design may...

Weather extremes are one important element of ongoing climate change, but their impacts are poorly understood because they are, by definition, rare events. If the frequency and severity of extreme weather events increase, there is an urgent need to understand and predict the ecological consequences of such events. In this study, we aimed to quantify the effects of snow storms on nest survival i...

A problem in climate studies has been on how to treat causal chains of explanations and both direct and indirect effects. Mammals in strongly seasonal environments of the boreal forest typically lose condition during winter and gain mass (and reproduce) during the summer season when biomass and plant quality peak. Mass decay of large herbivores during winter is due to direct effects of winter w...

This paper outlines our approach for describing multivariate environmental information such as weather as it might be characterized by humans using connotations and delicate nuances. The purpose of this research is to achieve smooth human-machine spoken dialogue. The key feature of our approach is the use of a vector-based method, a widely used technique in Information Retrieval research. To da...

Weather events have the ability to cause disruption to the road networks, both by making roads impassable, and by leading to a deterioration in safe driving conditions. Heavy snows in the winters of 2009 and 2010, as well as extreme flooding in 2011 and 2015, have demonstrated the ability of weather events to impact transport services and mobility. Within an Irish context there is very little r...

abstract in order to study the effects of irrigation regimes on physiological traits, yield and water use efficiency of potato (solanum tuberosum l.) in mashhad weather condition, an experiment was conducted in 2009 at research field of the college of agriculture, ferdowsi university of mashhad, using factorial experiment based on randomized complete blocks design with 3 replications. experimen...

Error in weather forecasting is due to inaccuracy both in the models used, and in the estimate of the current atmospheric state at which the model is initiated. Because weather models are thought to be chaotic, and therefore sensitive to initial condition, the technique of ensemble forecasting has been developed in part to address the latter effect. An ensemble of forecasts is made with perturb...

Adverse weather conditions have been shown to have a substantial impact on traffic flow operations following substantial adaptation effects in driving behavior. In quantifying these effects psycho-spacing models may be used. In this contribution it was examined to what extend adverse weather conditions influence the position of action points in the relative speed-spacing plane in these models, ...
