To improve high motion accuracy and efficiency in the high-speed operation of a 4-DOF (4 degrees of freedom) redundant parallel robot, this paper introduces a trajectory planning of the parallel robot in joint space based on the twelve-phase sine jerk motion profile.The 12-phase sine jerk motion profile utilizes the characteristics of a sine functi
ABSTRACTFruit bodies (sporocarps) of wild mushrooms growing in natural environments play a substantial role in the preservation of microbial communities, for example, clinical and food-poisoning bacteria.However, the role of wild mushrooms as natural reservoirs of plant pathogenic bacteria remains almost entirely unknown.Furthermore, bacterial tran
The issues of constructing high-rise, primarily residential, buildings have a great social significance.Not every plot of land, acquired in the Russian Federation is suitable for high-rise construction.Therefore, every construction company wood dpn that plans to erect a multi-apartment building, a high-rise office building, or a skyscraper must tak
In recent years, underwater shield tunnels are being developed according to large-scale sections.The problems of large buried depth and high water pressure have posed major challenges to the safety of Preorder segmented structures.The load-bearing capacity and damage of segmented structures under high water pressure features have always attracted a
