[1] The observed differences between complex craters and multi-ringed basins are described and a combined ‘‘transient cavity/displaced zone/melt cavity’’ model is explored to account for the observations. In this ‘‘nested melt-cavity model’’, the increasing influence of the percentage of the target undergoing impact melting at the sub-impact point with increasing size (the differential melt sca...

One of the main objectives of the forensic sciences is establishing a person's identity which can be a very complex process. The analysis of the teeth, fingerprints and DNA evaluation are probably the most used techniques allowing fast and secure identification processes. Palatal rugae or transverse palatine folds are asymmetrical and irregular elevations of the mucosa located in the anterior t...

Phragmites australis, a native helophyte in coastal areas of the Baltic Sea, has significantly spread on the Finnish coast in the last decades raising ecological questions and social interest and concern due to the important role it plays in the ecosystem dynamics of shallow coastal areas. Despite its important implications on the planning and management of the area, predictive modeling of Phra...

Abstract We propose a method for thermal expansion compensation of reference monolithic optical cavities laser frequency stabilization. Two schemes are considered: Fabry–Perot interferometer with crimp ring and whispering-gallery-mode cavity clamp. In each scheme, is achieved due to the strained connection an element made material high coefficient expansion. The temperature range cavities’ leng...

Different nose shape can cause a significant influence on the water entry trajectory and cavity. In order to study evolution characteristics of cavity asymmetric in process entry, based high-speed photography technology, low-speed comparative experiments were carried out for three different cut-angle types 35°, 40° 45° under angles. Through digital image processing contour motion attitude infor...

Influence of the cheeks expansion during bilabial plosive production This experimental study highlights the influence of expansion of the cheeks during the production of bilabial plosives. The closure of the lips, before the plosive, causes an increase in intra-oral pressure. The assumption suggested in this paper is that the increase of oral cavity volume, as a result of the intra-oral pressur...

Displacement finite element analysis is performed for a cone-penetration test in cohesionless soils. By modelling finite strain in the soil and large scale sliding at the penetrometer–soil interface, a more realistic penetration process is simulated in which the penetrometer is assumed to be rigid and the soil is assumed to be an elastic-perfect-plastic continuum obeying the Mohr–Coulomb criter...

The problem of oblique wave scattering of a Rayleigh wave by a cylindrical cavity in an elastic half-space is solved using the multipole expansion method. Whereas in the analogous water-wave problem a single scalar field is expressed as an infinite multipole expansion, and in the Rayleigh wave case with normal incidence two scalar fields suffice, here we require three coupled scalar multipole e...

A supersonic expansion containing acetylene seeded into Ar and produced from a circular nozzle is investigated using CW/cavity ring down spectroscopy, in the 1.5 lm range. The results, also involving experiments with pure acetylene and acetylene-He expansions, as well as slit nozzles, demonstrate that the denser central section in the expansion is slightly heated by the formation of acetylene a...

Experiments with the transverse Doppler effect have demonstrated that the wavelength of light increases with the speed of the source relative to the observer. The relativity principle implies that such a change cannot be detected by in situ measurements and this prediction has been verified by wavelength determinations carried out with a cavity resonator over an extended period of time during w...
