Using neural networks to predict road roughness
When a vehicle travels on a road, different parts of vehicle vibrate because of road roughness. This paper proposes a method to predict road roughness based on vertical acceleration using neural networks. To this end, first, the suspension system and road roughness are expressed mathematically. Then, the suspension system model will identified using neural networks. The results of this step sho...
متن کاملRoad Safety Analysis Using Web-based Collaborative Gis
Road accidents have a definite impact in terms of lives, welfare and traffic congestion, especially with increase in mobility and number of overall vehicles. Prevention policies can greatly benefit from data analysis of positions and accident characteristics. This work presents a practical integration of open source software for the implementation of an instrument to insert, store, automaticall...

در این تحقیق شبکه عصبی مصنوعی برای پیش بینی مقادیر ضریب اطمینان و فاکتور ایمنی بحرانی سدهای خاکی ناهمگن ضمن در نظر گرفتن تاثیر نیروی اینرسی زلزله ارائه شده است. ورودی های مدل شامل ارتفاع سد و زاویه شیب بالا دست، ضریب زلزله، ارتفاع آب، پارامترهای مقاومتی هسته و پوسته و خروجی های آن شامل ضریب اطمینان می شود. مهمترین پارامتر مورد نظر در تحلیل پایداری شیب، بدست آوردن فاکتور ایمنی است. در این تحقیق ...
Evaluating Organizational Performance Based on Safety Management Using Data Envelopment Analysis; Case Study: Isfahan Car Industry
Occupational accidents severely deteriorate human capital, and hence negatively affect the productivity and competitiveness. But despite these negative points, there are still deficiencies in safety management performance and indicators. Therefore the safety issue needs an active management. For this reason, the writer has proposed an approach to evaluate organizations based on safety managemen...
