A New Technique for Quality Assessment of Railway Ballast Materials
The influence of main quality tests on the overall quality of railway ballast materials is assessed in this study. The need to integrate all acceptance tests in a unified manner for precise evaluation of ballast quality is identified, and a technique of performing this is proposed. Using this approach, a new ballast quality index (BQI) is defined in which, the main acceptance tests including ab...

تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...
Calibration Of Railway Ballast DEM Model
The ballast of the railway track is constantly changing due to dynamic forces of train traffic that results in the crushing of the rocks. The feasibility to simulate each particle makes the discrete element method (DEM) suitable for the task. Different DEM particle models are introduced in our paper and the adequate one was chosen. This new method is based on crushable convex polyhedral element...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
