Continuous overturn control of compactors/rollers by rollover protective structures

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

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

Dynamic Response of a Rollover Protective Structure

Roll Over Protective Structures (ROPS) are safety devices fitted to heavy vehicles to provide protection to the operator during an accidental roll over. At present, ROPS design standards require full scale destructive testing which can be expensive, time consuming and unsuitable for small companies. More economical analytical methods are not permitted due to a lack of understanding on post yiel...

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

Cost effectiveness of a dealer's intervention in retrofitting rollover protective structures.

OBJECTIVE To evaluate the cost effectiveness of a 4.5 year education campaign that promoted farmers' adoption of rollover protective structures (ROPS) to prevent tractor overturn injuries. DESIGN Randomized controlled trial, decision analysis, and cost effectiveness analysis. SETTING One treatment county and one control county in the State of Kentucky. INTERVENTION A campaign by a local t...
