We report results from the first mid-infrared spectroscopic study of a comprehensive sample of 33 LINERs, observed with the Spitzer Space Telescope. We compare the properties of two different LINER populations: infrared-faint LINERs, with LINER emission arising mostly in compact nuclear regions, and infrared-luminous LINERs, which often show spatially extended (non-AGN) LINER emission. We show ...

We explore the three-dimensional interaction of higher acoustic modes with bias-flow perforated liners in cylindrical and annular ducts. Pressure fluctuations in the vicinity of the liners excite the production and shedding of vorticity from the rims of apertures in the liners. An effective liner compliance is used which accounts for this transfer of acoustical into vortical energy. The investi...

A ball mill is a heavy mechanical device and its safe operation affects the entire grinding process. Mill load key index in optimum of process, but it cannot be measured directly. In industrial practice, operational experts normally estimate value based on their experiences signals produced by mill. this paper, we proposed heterogeneous selective ensemble method using multiscale frequency spect...

The thesis is based on these four original papers 1.

BMJ Open 2013; 3: e003417. (Study I) 2. Rohde U, Hedbäck N, Gluud LL, Vilsbøll T, Knop FK. Effect of the EndoBarrier Gastrointestinal Liner on...

Mill load (ML) estimation plays a major role in improving the grinding production rate (GPR) and the product quality of the grinding process. The ML parameters, such as mineral to ball volume ratio (MBVR), pulp density (PD) and charge volume ratio (CVR), reflect the load inside the ball mill accurately. The relative amplitudes of the high-dimensional frequency spectrum of shell vibration signal...

The role of Supernova Remnants (SNRs) for the production of the Galactic Cosmic Rays is reviewed from the point of view of theory and very high energy gamma-ray experiments. The point is made that theory can describe young SNRs very well, if the evidence from the synchrotron emission is used to empirically determine several parameters of the theory, and thus theory can predict the relative cont...

The oxidation performance of silicon carbide (SiC) coating on nuclear fuel particle and the subsequent effect mechanical integrity was investigated. effects steam content phase composition microstructure SiC layer at different temperatures were discussed. Reaction rates with found to obey liner-parabolic law. fracture strength shell evaluated, which dominated by thickness variation SiC. Further...

PURPOSE Dissociation of the polyethylene liner is a known failure mechanism of the Harris Galante I and II uncemented acetabular components. The outcomes of revision surgery for this indication and the influence of time to diagnosis are not well described. METHODS We report a series of 29 cases revised due to this failure mechanism. The median time from primary to revision surgery was 13 year...
