Available in PDF, EPUB and Kindle. Book excerpt: Modification and refinements of equipment, techniques and method of analysis of wake survey data for determining the viscous drag of a ship model are described. At low Froude numbers results are in better agreement with a correlation line than previous values, but strong variation of viscous drag with Froude number is confirmed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The purposes of the present work were to evaluate the validity and accuracy of the various viscous drag formulas, to investigate the influence of turbulence in the wake, and to study the feasi bility of a practical, routine technique for making viscous-drag measurements. An exact formula for the viscous drag was derived in a recent paper, in which two new approximations and evaluation of their errors by means of a mathematical model were also presented. The momentum-control surface selected in this case is a rectangular box moving with the ship model at a constant speed U in the negative x-direction. This control surface consists of two vertical transverse sections, S sub O, far ahead of the model, and S, at a moderate distance behind it, over which the measurements are to be taken; the free surface, through which there is no momentum flux; and bottom and sides, which are situated at great distance from the model. It was assumed that the flow is irrotational outside the wake and that this external potential flow could be continued analytically into the wake by a suit able distribution of sources and sinks within the ship model and the wake.

Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a real-time method based on the law of the wake for estimating forebody skin-friction coefficients. The incompressible law-of-the-wake equations are numerically integrated across the boundary layer depth to develop an engineering model that relates longitudinally averaged skin-friction coefficients to local boundary layer thickness. Solutions applicable to smooth surfaces with pressure gradients and rough surfaces with negligible pressure gradients are presented. Model accuracy is evaluated by comparing model predictions with previously measured flight data. This integral law procedure is beneficial in that skin-friction coefficients can be indirectly evaluated in real-time using a single boundary layer height measurement. In this concept a reference pitot probe is inserted into the flow, well above the anticipated maximum thickness of the local boundary layer. Another probe is servomechanism-driven and floats within the boundary layer. A controller regulates the position of the floating probe. The measured servomechanism of this second probe provides an indirect measurement of both local and longitudinally averaged skin friction. Simulation results showing the performance of the control law for a noisy boundary layer are then presented.

Book excerpt: The biennial Congress of the Italian Society of Oral Pathology and Medicine (SIPMO) is an International meeting dedicated to the growing diagnostic challenges in the oral pathology and medicine field. The III International and XV National edition will be a chance to discuss clinical conditions which are unusual, rare, or difficult to define. Many consolidated national and international research groups will be involved in the debate and discussion through special guest lecturers, academic dissertations, single clinical case presentations, posters, and degree thesis discussions. The SIPMO Congress took place from the 17th to the 19th of October 2019 in Bari (Italy), and the enclosed copy of Proceedings is a non-exhaustive collection of abstracts from the SIPMO 2019 contributions.
