Four cloud-seeding cases over southern Idaho during the 2010/11 winter season have been simulated by the WeatherResearch and Forecasting (WRF)model using the coupled silver iodide (AgI) cloud-seeding scheme that was described in Part I. The seeding effects of both ground-based and airborne seeding as well as the impacts of model physics, seeding rates, location, timing, and cloud properties on ...

We present a study of homogeneous crystal nucleation from metastable fluids via the seeding technique for four different systems: mW water, Tosi-Fumi NaCl, Lennard-Jones, and Hard Spheres. Combining simulations of spherical crystal seeds embedded in the metastable fluid with classical nucleation theory, we are able to successfully describe the nucleation rate for all systems in a wide range of ...

Edible-oil flax (Linum usitatissimum L.) can be an alternate oil-seed crop in Isfahan region. Seeding date is very important in obtaining higher grain yields and a successful flax production. The present study was conducted at the research farm, Isfahan University of Technology in the year 2000 to determine the effect of seeding date and genotype on yield, yield components and maturity of edibl...

We propose to generate steady-state microbunching in a storage ring with a reversible seeding scheme. High gain harmonic generation (HGHG) and echo-enabled harmonic generation (EEHG) are two promising methods for microbunching linac electron beams. Because both schemes increase the energy spread of the seeded beam, they cannot drive a coherent radiator turn-by-turn in a storage ring. However, r...

According to the agronomic requirements of cotton precision seeding, researchers designed a split seeding system achieve high-speed on membrane. The 3D models used in simulation process were created using Solidworks. They built-in Flow Simulation plug-in SolidWorks simulate flow field drum and grasp air velocity pressure changes. CFD-DEM (computational fluid dynamics discrete element method) co...

This paper provides nested sets and vector representations of knockout tournaments. The paper introduces classification of probability domain assumptions and a new set of axioms. Two new seeding methods are proposed: equal gap seeding and increasing competitive intensity seeding. Under different probability domain assumptions, several axiomatic justifications are obtained for equal gap seeding....

A novel rotor was constructed to allow for the seeding of porous scaffolds via centrifugal force. Using cell seeding times of 10 min, this method placed significantly (roughly 3-fold) more cells into poly(glycolic acid) scaffolds than 24 h of spinner flask seeding or static seeding. There were no significant differences in the mitochondrial activity per cell between the 3 seeding methods. Cell ...

گونه راش یکی از فراوانترین و از نظر اقتصادی مهمترین درختان جنگلهای شمال ایران است. تعیین ساختار هر توده و ترکیب آن با خصوصیات جنگل‌شناسی که شامل آمیختگی، سن، ساختار عمودی یا اشکوب‌بندی، ساختار افقی، وجود یا عدم وجود روزنه، تاج پوشش، انبوهی، وجود و یا عدم وجود زادآوری یا زیراشکوب درختی و درختچه‌ای است می‌تواند ما را در دستیابی به یک مدیریت مناسب و فراگیر، یاری نماید. در این پژوهش خصوصیات مورفول...
