Wakamatsu Tilting Modules , U - Dominant Dimension and k - Gorenstein Modules ∗ †
Let Λ and Γ be left and right noetherian rings and ΛU a Wakamatsu tilting module with Γ = End(ΛT ). We introduce a new definition of U -dominant dimensions and show that the U -dominant dimensions of ΛU and UΓ are identical. We characterize k-Gorenstein modules in terms of homological dimensions and the property of double homological functors preserving monomorphisms. We also study a generaliza...

The aim of this study was the comparison of plantar pressure distribution, vertical ground reaction force and contact area between dominant and none-dominant limb in top-flight females taekwondo.10 healthy young top-flight females taekwondo were selected. plantar pressure ,vertical ground reaction force and contact area were evaluated by emed system .The obtained data were analyzed by paired -t...
متن کاملDynamics Study of Ankle Joint during Quiet Standing Balance Control with Emphasis on Dominant and Non-dominant Lower Limb
Purpose: The present study aimed to evaluate the effect of dominant lower limb on the correlation between some of the dynamic variables of ankle joint and center of mass during quiet standing balance control. Methods: Twelve healthy females with no known neurological or musculoskeletal disorders, with the mean age of 26±3.5 years, participated in this study. Motion analysis system, force ...
متن کاملComparing Dominant and Non-Dominant Hand Performance with Force Changes In a Two-Hand Equilibrium Task: A Challenge to Dominant Hand Theories
Objective: Although most studies believe that the dominant hand performs better than the non-dominant hand in performing various tasks, there is still the challenge among researchers as to why the non-dominant hand performs better than the dominant hand in certain situations and tasks. The aim of this study was to compare dominant and non-dominant hand performance with force changes in a two-ha...
متن کاملk-dominant and Extended k-dominant Skyline
Skyline queries have recently attracted a lot of attention for its intuitive query formulation. It can act as a filter to discard sub-optimal objects. However, a major drawback of skyline is that, in datasets with many dimensions, the number of skyline objects becomes large and no longer offer any interesting insights. To solve the problem, k-dominant skyline queries have been introduced, which...
