Introduction: Cranes are of the major causes of accidents in the construction industries. As human error mostly causes crane accidents, this study aims to investigate the human errors of tower crane operators in the construction projects using SHERPA and CREAM techniques. Material and Method: In this research, first, all of the tasks of the tower crane operator were identified and analyzed. Th...
The paper discusses the security of compression function and hash function with Merkle-Damg̊ard construction and provides the complexity bound of finding a collision and primage of hash function based on the condition probability of compression function y = F (x, k). we make a conclusion that in Merkle-Dammåard construction, the requirement of free start collision resistant and free start collis...
We revisit the computation of probability collision in context automotive avoidance (the estimation a potential is also referred to as conflict detection other contexts). After reviewing existing approaches definition and we argue that question “What within next three seconds¿‘ can be answered on basis rate. Using results level crossings for vector stochastic processes derive general expression...
In this paper, the behavior of a typical jack-up platform under accidental loading of ship collision was investigated. The studied platform was modeled using ANSYS software and analyzed dynamically under ship impact. The platform was also analyzed dynamically under secondary ship impact. The initial collision results showed that the main energy absorption mechanism in impact to jack-up platform...
Superquadric modeling technology applied to the description of various shapes of robot links is discussed in the paper. Through a series of homogeneous transformations between the robots’ links, which have been modeled as a specified superquadric form, ellipse, the complexity of the collision detection problem can be reduced when evaluating the relative location between a transformed ellipse an...
