Models to predict the force to operate front foldable rollover protective structures for narrow-track tractors

Farm tractor rollover protection: why simply getting rollover protective structures installed on all tractors is not sufficient.

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

A Study to Predict the Development of Wear for the Wheel/interface of a Railway Track

The train transport is often confronted with greatly repeated changes in scope, vehicle travel well-being and transport safety because of the adjustments of wheel and rail profiles. These problems are frustrating and threatening. Thus, there is a requirement for an approach to predicting the wear of wheel/rail to tackle these problems. A new theoretical ground is broken through the build-up a m...

The Behaviour of Rollover Protective Structures subjected to Static and Dynamic Loading Conditions

Hybrid Models Performance Assessment to Predict Flow of Gamasyab River

Awareness of the level of river flow and its fluctuations at different times is one of the significant factor to achieve sustainable development for water resource issues. Therefore, the present study two hybrid models, Wavelet- Adaptive Neural Fuzzy Interference System (WANFIS) and Wavelet- Artificial Neural Network (WANN) are used for flow prediction of Gamasyab River (Nahavand, Hamedan, Iran...
