[1] Using a stereo pair of HiRISE images of a pole‐facing crater slope at 38°S, 218°E, we measure topographic profiles along nine gullies. Typical slopes of the interior channel region (above the depositional apron) are ∼20°. We test the hypothesis that sediment transport on gully slopes occurs via fluvial transport processes by developing a numerical sediment transport model based on steep flu...
Varied flows such as flooding resulting from dam break can happen due to earthquakes, seepage, bombing, overtopping, mistake in design and project performance as well as causing financial damages and human losses. Unsteady flow during flooding events has a high impact on flow field pattern, sediment motion, ecology and also, distribution of contamination in the river. In this study, the impact ...
مساله مکان?یابی ماکزیمم پوشش از جمله پرکاربردترین مسائل مکان?یابی محسوب می شود. در این مساله هدف تعیین مکان p مرکز سرویس و تخصیص نقاط تقاضا به آنها به گونه ای است که جمعیت سرویس داده شده ماکزیمم شود. یک از معیارهایی که موجب افزایش کیفیت خدمات رسانی توسط مراکز سرویس می شود، توجه به میانگین زمان انتظار در مراکز سرویس می باشد. در این رساله سه مساله مکان یابی ماکزیمم پوشش مورد بررسی قرار می گیرد....
We present preservation theorems for countable support iteration of nep forcing notions satisfying “old reals are not Lebesgue null” (section 6) and “old reals are not meager” (section 5). (Nep is a generalization of Suslin proper.) We also give some results for general Suslin ccc ideals (the results are summarized in a diagram on page 17). This paper is closely related to [She98, XVIII, §3] an...
In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...
A three-dimensional numerical model is used to compute the water flow field in a straight flume with a cobble bed. The geometry of the numerical model is a replication of a physical model experiment where the largest cobbles were approximately 10 cm long. Detailed information on the digital terrain model of the bed was available from a laser scan of the bed. In the experiments, flow velocity pr...
Failure of the bridges due to local scour around their piers can cause serious life losses and property damages and create significant environmental problems. In this experimental study, scour hole geometry around circular bridge piers were investigated. The experiments were carried out in a rectangular flume 80 cm wide, 18.6 m long and 75 cm high by using uniform sediment with a median diamete...

The effectiveness of submerged synthetic aquatic vegetation on removal colloids from flowing water was investigated to explore retention particulate nonpoint source pollutants in systems. In colloid transport experiments, the deposition rate coefficient dense is often taken as spatially constant. This assumption tested by experiments and modeling aimed at quantifying changes with travel distanc...
Since the initial announcement of evidence for oscillations of atmospheric neutrinos [1], Super{ Kamiokande has increased its atmospheric neutrino sample by 40% to 45.3 kiloton-years of fullycontained interactions and 42.2 kiloton-years of partially-contained interactions. The data exhibit signi cantly low values of R ( ( =e)DATA=( =e)MC) in both the sub-GeV sample (R = 0:67 0:02 0:05) and mult...
