Safe Takeoffs-Soft Landings

Safe Takeoffs - Soft Landings

The richness of life’s possibilities creates a paradox. It poses fundamental limitations on the ability of an organism to reason and act intelligently, as information in its environment is often ambiguous and consistent with an infinite number of interpretations. At the same time, interpretation of this information is required for intelligent action. To further complicate the situation, many pr...

Influence of Externally Damping on Impact-induced Soft Tissue Vibrations and Muscle Responses in Landings

The aim of this study was to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different compression conditions (externally applied) in a drop-jump landing task. Twelve trained male participants were instructed to perform drop-jump landings from 3 heights in compression shorts (CS) and regular shorts without compression (CC). External...

Tibio-femoral Kinematics of Soft and Stiff Landings: A Biplane Fluoroscopy Study

INTRODUCTION: Though the exact mechanism of non contact anterior cruciate ligament (ACL) has not been fully clarified, several recent studies have suggested individuals who land with a stiff landing profile, defined as reduced knee flexion angles, may be at higher risk of ACL injury than individuals who land more soft [1,2]. The concepts and theories developed from these and other non-contact A...

Geographic Information Systems Based Quantity Takeoffs in Buildings Construction

Paper presents a Geographic Information System (GIS) based quantity takeoffs methodology, which is helpful in increasing the productivity of quantity estimator by reducing the manual work in quantity takeoffs. Proposed methodology also reduces the missing or duplication of various items of work by visualizing each components corresponding to the items in space. Several scripts developed within ...
