Different postural stability may be a contributor to secondary injuries in individuals with flexible flatfeet (FF) compared to those with neutral feet (NF). However, the differences between static and dynamic stability of FF and NF have not been examined. This study compared the static and ...
Introduction to aircraft flight mechanics : performance, static stability, dynamic stability, classical feedback control, and state-space foundations Thomas R. Yechout with contributions by Steven L. Morris, David E. Bossert, Wayne F. Hallgren, James K. Hall (AIAA education series) American Institu...
Wind tunnel tests have evidenced that there exists reversed evolution between aerodynamic static stability and dynamic stability of testing model, i.e.,within the range of static stability increase, dynamic stability decreases, or vice verse.Studies have shown that major reason for this aerodynamic phe...
An automatic static compensator shunt connected at the synchronous generator terminals using an appropriate control strategy is shown to yield superior dynamic stability limits than that of a conventional or a dual excited machine. The control signal to actuate the static compensator is derived from a...
Finally, the stability properties as well as impulse responses of this type of bearing, which simulates variation in film gap caused by imperfect guideway geometry, are demonstrated in the current paper. Introduction Aerostatic bearings have been widely used for high precision mechanisms because of ...
Investigating the Immediate Effects of Static and Dynamic Stretching Exercises of Lower Extremities Muscles on Core Stability in Young Healthy Females Introduction: This study investigates the immediate effects of warm-up exercises, specifically static and dynamic stretches for the lower extremities, on s...
Animal performance fundamentally influences behaviour, ecology, and evolution. It typically varies monotonously with size. A notable exception is maximum running speed; the fastest animals are of intermediate size. Here we show that this peculiar allomet
6e, adjusting the stability of ASO/BS to approximately −8 to −10 kJ/mol from the ΔG310K value between ASO/mRNA can possibly promote the active involvement of TMSD. We also should care that an exaggerated affinity of ASO against target RNA has been demonstrated to be detrimental to ...
The thoracic cage plays an important role in maintaining the stability of the thoracolumbar spine. In this study, the influence of a rib cage on static and dynamic responses in normal and scoliotic spines was investigated. Four spinal finite element (FE) models (T1–S), representing a normal...
The temporal stability of different types of contexts may play an important role in supporting this memory-chunking process. Increasing evidence shows that items encountered in a shared, or stable, context (e.g., appearing in the same room) become linked together in memory5,6,7,8,9,10. By...
