this research investigates the vegetation of 4600 ha of polour semi-steppe rangelands in relation to edaphic and physiographical parameters in mazandaran province. for this purpose, 23 land units were selected from overlaying slope, aspect and elevation maps using geographic information system (gis). within each unit, 3 parallel transects with 100 m length, each containing 10 quadrates (accordi...

studying risk and frequency analysis of flood is done in order to design structures located in floody lands. in hydrological and water resources engineering projects, first of all, we should determine frequency of this phenomenon- their return period. in this research, the method of planning, the cumulative freguency curve is explained and probability and return period and errors concerning sma...

This study investigates the dynamics of three discrete independent events occurring randomly and repeatedly within interval [0,T]. Each event spans a predetermined fraction γ total length T before concluding. Three continuous random variables represent starting times these events, uniformly distributed over time By employing geometric probability approach, we derive rigorous closed-form express...

Probability-matching is a phenomenon where people, given a repeated choice between alternatives with different payoff rates, select each alternative proportional to its payoff rate. We attempt to isolate the strategy responsible for this generally irrational behavior using Bayesian data analysis to score three models over three conditions. While two strategies were broadly utilized, one causing...
