Traktörler tarım sektöründe en yaygın kullanılan makinelerden biridir. Tarım kazaların büyük bir bölümü traktörlerin devrilmesi ile oluşmaktadır. Devrildikten sonra sürücünün hayatta kalabilmesi için bazı pasif güvenlik tedbirlerinin alınması gerekmektedir. Özellikle kabinsiz traktörlerde ROPS (Roll-Over Protective Structure) adı verilen bu mekanizma devrilme esnasında traktör altında kalması ö...

This white paper lays out some foundational information about different approaches to safety: how various industries differ in their approaches to safety engineering, and a comparison of three general approaches to safety (system safety, industrial safety engineering, and reliability engineering). An attempt is made to lay out the properties of industries and systems that make one approach more...

Safety case development is not a post-development activity, rather it should occur throughout the system development lifecycle. The key components in a safety case are safety arguments. Too often, safety arguments are constructed without proper reasoning. Inappropriate reasoning in safety arguments could undermine a system’s safety claims, which in turn contributes to safety-related failures of...

atropine has been used for more than a century by small groups of researchers to arrest myopia progression, and lately has gathered compelling evidence of its protective effect from well-designed clinical studies, mainly performed during the last two decades. however its exact mechanism of action is an unsettled issue. experimental finding has shown that it is not related to accommodation, as i...

For any software system upon which lives depend, the most important question one can ask about it is, ‘How do we know the system is safe?’ Despite the critical importance of this question, no widely accepted, generally applicable answer exists. Instead, debate continues to rage over the question, with theorists and practitioners quarrelling with each other and amongst themselves. This paper sug...

kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...
