مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
In this paper, a new distribution of the three-parameter lifetime model called the Marshall-Olkin Gompertz is proposed on the basis of the Gompertz distribution. It is a generalization of the Gompertz distribution having decreasing failure rate and can also be increasing and bathtub-shaped depending on its parameters. The probability density function, cumulative distribution function,...
in this paper, we propose and study exp-kumaraswamy distribution. some of its properties are derived, including the density function, hazard rate function, quantile function, moments, skewness and kurtosis. adata set isused to illustrate an application of the proposed distribution. also, we obtain a new distribution by transformation onexp-kumaraswamy distribution. new distribution is an...
Landslide is one of the natural disasters which cause a lot of annual damage directly or indirectly in the world. Land use changes and high rainfall are leading causes of creation this phenomenon in Beheshtabad basin. Therefore the effective factors were analyzed in this process. The main aim of this study is comparison of two methods AHP and FAHP that are used in landslide hazard zonation by c...
Abstract Hazard maps are essential tools to aid decision makers in land-use planning, sustainable infrastructure development, and emergency preparedness. Despite the availability of historical data, there has been no attempt produce hazard for Kuwait. In cooperation with World Bank, this study investigated natural anthropogenic hazards that affect The objective was assess face Kuwait map most c...
Synonymy is a pivot relation in NLP but remains problematic. Putting forward, we introduce the notion of relative synonymy, to circumvent some diÆculties among which possible polysemy and contextual interpretation. In the framework of conceptual vectors, it is then possible to formalize test functions for synonymy and to experiment their use in thematic analysis that will help text classi cation.
Flood as a natural disaster follows certain erratic patterns which was made confounding factor. Flood risk is variable and complex that depends on very phenomena such as rainfall, runoff concentration and high exposure of the flooding downstream areas. This are changes over time and from regions due to natural conditions, human activities, and damage culture...
introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...
