Variations in the origin of arteries in the abdomen are very common but with the invention of new operative techniques within the abdominal cavity, the anatomy of abdominal vessels has assumed much more clinical importance. During routine dissection of the abdominal cavity, we came across multiple arterial anomalies involving testicular and suprarenal arteries. On the right side, there was doub...
Based on the improved three-dimensional finite element model, this paper studies load transfer mechanism of pile-supported reinforced embankments. The model uses an elastic medium to replace soft soil subgrade, which reduces calculation depth subgrade and improves efficiency model. validity is proven by field test results theoretical results. By changing cohesion, internal friction angle, modul...
We present in this paper the behavior of an artificial agent who is a member of a crowd. The behavior is based on the social comparison theory, as well as the trajectory mapping towards an agent’s goal considering the agent’s field of vision. The crowd of artificial agents were able to exhibit arching, clogging, and bursty exit rates. We were also able to observe a new phenomenon we called doub...
Application of Mineral Compounds for a High-Voltage Portable Grounding System: An Experimental Study
Electrical grounding is an indispensable part of the power system network. The mainly affected by resistance and nature soil. High ground produces phenomenon soil ionization, surface arching, back flashover. A conventional requires deep digging electrodes, thus creating maintenance difficulties. This research work focuses on safe operation electric from external internal impulses arising due to...
Experimental and numerical tests of the trap-door problem have been carried out, involving several granular materials. Three phases have been observed in the load transfer mechanism, as the trap-door is moved downward. The classical pattern for the description of this type of problem (a vertical plane of failure at each edge of the trap-door) corresponds to the third phase observed. The previou...
درک الگوی توزیع مکانی ماکروفون خاک بدلیل اثرات آن روی فرآیندهای اکوسیستم بسیار مهم است. لیکن اطلاعات کمی در این خصوص وجود دارد. درمورد تنوع زیستی ارگانیسم ها وجانداران خاکزی که ازاجزای مهم وکلیدی درهرسیستم اکولوژیکی هستند و در بهبود حاصلخیزی خاک و تولیدات زمین وپایداری اکوسیستم ها(ازطریق فرآیندهای بیولوژیک)نقش عمده دارند تحقیقات کمی انجام شده است. این تحقیق جهت بررسی الگوی مکانی پارامترهای تنوع...
Piled foundations are commonly employed to reduce settlements of artificial earth embankments on soft soil strata and geosynthetic reinforcements installed at the embankment base increase pile spacing construction costs. Despite well-documented effectiveness this technique, mechanical processes, developing during in different elements constituting ‘geo-structure’, not fully understood design ap...
