Abstract: Consulting engineering companies need an adequate cost control system to improve their profitability and productivity. Cost control enables the firm to make decisions if the measurements do not comply with the initial ...

Abstract: This article concerns the use of an active control applied to a reduced scale riser undergoing vortexinduced vibrations (VIV). The control system relies upon the fact that a flexible structure undergoing VIV oscillates at ...

Abstract: The use of the describing-function method has been generally limited to systems with nonlinearities which can be combined in a block diagram of a feedback control system which is represented ...

Abstract: A method is proposed to calculate the interaction between an oscillating body and the water surrounding it for low values of the Keulegan‐Carpenter number and in laminar flow conditions. Rather than dividing the viscous ...

Abstract: This paper explores the merits of shape memory wave springs as powering elements of solid-state actuators. Advantages and disadvantages of the wave construction in comparison to the traditional ...

Abstract: This technical note presents a method for calculating the flow from springs and may be useful in the management of aquifers where the spring flow is a critical factor. The note examines the conjunctive operation of a ...

Abstract: he quantitative estimation of rain rates using meteorological radar has been a major theme in radar meteorology and radar hydrology. The increase of interest in polarimetric radar is in part because polarization diversity ...

Abstract: n assessment of the performance of a self-consistent numerical method for dual-frequency radar based on the retrieval of microphysical precipitation parameter profiles is presented. From the surface reference technique ...

Abstract: Monitoring of precipitation using high-frequency radar systems, such as the X band, is becoming increasingly popular because of their lower cost compared to their S-band counterpart. However, at higher frequencies, such ...

Abstract: This paper presents a procedure for calculating the effective equivalent structural properties (stiffness and damping) of hysteretic systems from the time histories of their dynamic response. The method is based on the ...
