“…IMF no. 4,5,6 in the vertical displacement as can be seen in Figure 7. The presence of large mean bandwidth (MBW) values in Table 1 also confirms the existence of large amount of energy in different frequencies other than the main frequency.…”

“…Even so, the bridge started to response when the wind speed increased. This is because not only the small fluctuations in the oncoming flow, but also the signature turbulences generated by the bluff model itself serve as sources of excitation [6]. Laser displacement sensors were used to record the displacement time histories of vertical rotational and lateral motions.…”

“…the degree of the freedom of the rigid model, is fixed to 3 or 6 in the case of a state space representation. Information other than these 3 DOFs are screened out by the fixed order [6], which is the usual practice in identifying the flutter derivatives. The measurement of vertical and rotational displacement might carry some information that has been overlooked.…”

Abstract:It is useful to study directly the general motion of the bridge deck due to ambient wind excitations, especially for the purpose of monitoring the "aeroelastic status" of the structure. In the general motion, a sustained or exponentially modified sinusoidal oscillation is not available and the linear time invariant system assumption as is required by the flutter derivative model (e.g. [1]) is jeopardized. Besides, the existence of uncontrollable factors under operational conditions may also bring about the time varying features. As will be show in this paper, the non-stationarity in the general motion is usually stronger than expected, which may cast a doubt on current practices of applying stationary techniques on ambient vibration analysis. Therefore, it is suitable to have reliable signal processing techniques to pre-examine the measured ambient responses before processing them. In this paper, a joint time-frequency study is carried out, via wind tunnel experiments, on the aeroelastic vibration of a rigid sectional model. Hilbert transform combined with empirical mode decomposition method is used. Instantaneous frequency domain properties of aeroelastic vibrations are obtained. Time dependant features of the interactive system are revealed.The result of this study indicates that, as far as the experiment in this paper is concerned, the nonstationarity is stronger in the vertical and rotational motion than in the lateral motion.

“…S-amlodipine is the only vasoactive enantiomer of amlodipine [66], 2.5 mg of which is found to be equivalent in its efficacy and tolerability when compared with 5 mg amlodipine in the treatment of mild-to-moderate hypertension [67]. Hydrophilic salts of S-amlodipine and their hydrates for the treatment of hypertension or angina are claimed in WO03043989 [145]. They are stated to be more easily soluble in water than S-amlodipine and to show better bioavailability and potency.…”

Hypertension is common in renal transplant recipients (RTR) and may contribute to the high incidence of morbidity and mortality from cardiovascular disease. Its treatment is an important factor necessary to ensure long-term patient and allograft survival. Although all antihypertensive drugs are useful in RTRs, the most commonly used drugs are calcium-channel blockers and renin-angiotensin system inhibitors. This article briefly reviews traditional drugs together with new antihypertensive drugs under development, focusing on their possible advantages in RTRs. In addition, many patents reporting chemical processes and pharmaceutical formulations of these drugs are also summarised.
