We address fine-grained entity classification and propose a novel attention-based recurrent neural network (RNN) encoderdecoder that generates paths in the type hierarchy and can be trained end-to-end. We show that our model performs better on fine-grained entity classification than prior work that relies on flat or local classifiers that do not directly model hierarchical structure.
از جمله ویژگیهای مهندسی که سبب توجه به سازههای توریسنگی شده و کاربری آنها را بشدت افزایش داده است میتوان به انعطافپذیری، هزینههای کم ساخت و اجرا، نفوذپذیری، دوام و ایمنی کافی و تاب مکانیکی بالا اشاره کرد. یک بند توریسنگی با هر هدفی که ساخته شود، سرانجام بعد از مدت زمانی مخزن آن انباشته از رسوب میگردد. مخزن رسوبگذاری شده، شرایط هیدرولیکی جدیدی نسبت به قبل از رسوبگذاری فراهم میکند. در ...
Kerman and its surrounding towns consist of a flat alluvial plain of fine silt and clay materials. In morphological aspects, these sediments have a very gentle slope with the main infrastructure of the city build on them. Generally, the structure of undisturbed soils is developed over time due to the influence of environmental factors. Geological factors in Kerman fine-grained alluviums have ca...
In Iran, a large extent of the soils and water are facing with salinity; so the geotechnical properties of arid and saline soils are important for engineering design. In this study, the effects of salinity on geotechnical properties of fine-grained and coarse-grained soils containing fibrous clay minerals have been studied. The results showed that salinity was mostly a flocculated agent in fine...
The Effect of Niobium on the Formation of Nanostructured Low Carbon Steel Using Martensite Treatment
The formation of nano/ultrafine grained ferrite in low carbon steels containing different amounts of niobium was investigated using thermomechanical treatment which consisted of annealing of 85% cold rolled martensite with different parameters. The specimens were characterized by optical and scanning electron microscopy and Vickers hardness test. A lamellar dislocation cell structure was formed...
