the rectangular broad crested weirs are widely used to measure the water dischargewhich is one of the most popular tools in the irrigation canals particularly, in developingcountries.the present article is trying to demonstrate the results of an experimental work carriedout on rectangular broad crested weir with sloped upstream face to investigate the effect ofupstream slope on discharge effici...
Even though there exist lots of documents on Finite Element Strength Reduction Method, cohesion and internal friction angle in these materials are reduced through the same reduction factor, which fails to reflect either of their safe reserving quality or the quality to precisely match slope failure process and mechanism. As is known, the exterior angle circumcircle yield criterion DP1 of the ge...
Intelligent Forecasting Method for Slope Stability Estimation by Using Probabilistic Neural Networks
The purpose of this article is to demonstrate the application of probabilistic neural networks (PNNs) as a classification tool in the slope stability estimation. PNNs are applied to estimate slope stability according to the slope geometric shapes and soil mechanical parameters. Unlike other neural network training paradigms, PNNs are characterized by high training speed and their ability to pro...
Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking. Methods: This is a quasi-experimental study...
BACKGROUND This study analyzed the effect of preoperative T1 slope on cervical alignment and range of motion (ROM) after cervical disc arthroplasty (CDA) in patients with cervical degenerative disease. MATERIAL AND METHODS This retrospective study included 32 patients with single-level symptomatic cervical disc disease who underwent CDA with the Mobi-C cervical disc prosthesis and had a mean fo...
background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...
Diurnal mountain wind systems are local thermally driven wind systems that form over mountainous terrain and are produced by the buoyancy effects associated with the diurnal cycle of heating and cooling of the lower atmospheric layers. This chapter reviews the present scientific understanding of diurnal mountain wind systems, focusing on research findings published since 1988. Slope flows are e...
Modelling the presence and effect of a thin weak layer soil or rock in slope stability analysis performed through finite element method (FEM) presents several problems purely numerical nature. This paper deals with parametric three different 2D case studies (both ideal real) unstable potentially slopes containing soft band (or layer). The FEM software used is RS2 (Rocscience®). aim investigatin...
چکیده مطالعه ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین پریسا حسینی برای حفظ اراضی و افزایش امکان بهره برداری از خاک، آگاهی از ویژگیهای مختلف خاک ها ضروری است. در این تحقیق ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین در شهرستان قزوین مطالعه و ...
OBJECTIVE We performed a retrospective analysis of medical records and radiographic images of patients who never underwent spinal treatment including diagnosis. The objective of this study is to explain the biomechanical and physiologic characteristics of cervical alignment related to thoracic inlet angle including T1 slope changes in each individual. METHODS We reviewed the cervical CT radio...
