It is well known that the oxygen uptake kinetics during rest-to-work transition (V(O2) on-kinetics) in trained subjects is significantly faster than in untrained individuals. It was recently postulated that the main system variable that determines the transition time (t(1/2)) of the V(O2) on-kinetics in skeletal muscle, at a given moderate ATP usage/work intensity, and under the assumption that...

OBJECTIVE To compare the effect of a whole body vibration training (WBVT) programme with a conventional training (CT) programme on knee proprioception and postural stability after anterior cruciate ligament (ACL) reconstruction. METHODS Twenty athletes with unilateral ACL reconstruction were randomly assigned to the WBVT or CT group; all participants received 12 sessions of WBVT or convention...

Objective: To determine the effect of whole body vibration training program (WBVT) in comparison with conventional training (CT) program on knee proprioception and postural stability after anterior cruciate ligament (ACL) reconstruction. Methods: Twenty athletes with unilateral ACL reconstruction were randomly assigned in two groups; WBVT and CT, all participants received 12 sessions of WBVT or...

Cylindrical liquid jets are inherently unstable and eventually break into drops due to the Rayleigh-Plateau instability, characterized by the growth of disturbances that are either convective or absolute in nature. Convective instabilities grow in amplitude as they are swept along by the flow, while absolute instabilities are disturbances that grow at a fixed spatial location. Liquid jets are n...

Recently the author of this article proposed a new signal processing algorithm for an all fiber white light interferometer. In this article, an all fiber white light interferometric absolute temperature measurement system is presented using the previously proposed signal processing algorithm. Stability and absolute temperature measurement were demonstrated. These two tests demonstrated the feas...

1 Absolute frequency measurement of Mid Infrared secondary frequency standard at BNM-LPTF G. D. Rovera, , Member, IEEE and O. Acef Abstract|An absolute frequency measurement of a CO2=OsO4 secondary frequency standard, operating in the mid infrared, is reported. A brief description of the measurement chain linking this standard to a hydrogen maser evidences the critical points. The measured freq...

introduction: the purpose of this study was to compare the effect of a whole body vibration training (wbvt) protocol with a conventional physiotherapy (pt) program on knee joint position sense and balance after anterior cruciate ligament (acl) reconstruction. methods: the study was designed as a single blind rct, twenty athletes with unilateral acl reconstruction were randomly assigned to the w...

This paper deals with the absolute stability analysis for uncertain time delay Lur’e systems that have time-varying delays and sector and slope restricted nonlinearities. New delaydependent stability criteria are derived via linear matrix inequality (LMI) formulation that can be easily solved by various optimization techniques. Sector bounds and slope bounds are employed to the Lyapunov–Krasovs...

The stability of the standard model is determined by the true minimum of the effective Higgs potential. We show that the potential at its minimum when computed by the traditional method is strongly dependent on the gauge parameter. It moreover depends on the scale where the potential is calculated. We provide a consistent method for determining absolute stability independent of both gauge and c...

Spatiotemporal chaos in the complex Ginzburg–Landau equation is known to be associated with a rapid increase in the density of defects, which are isolated points at which the solution amplitude is zero and the phase is undefined. Recently there have been significant advances in understanding the details and interactions of defects and other coherent structures, and in the theory of convective a...
