Additive manufacturing (AM) has gained high research interests in the past but comes with some drawbacks, such as difficulty to do in-situ quality monitoring. In this paper, deep learning is used on electron-optical images taken during Electron Beam Melting (EBM) process classify of AM layers achieve automatized assessment. A comparative study several mainstream Convolutional Neural Networks be...

Acoustic tomography is presented as a technique for remote monitoring of meteorological quantities. This method and a special algorithm of analysis can directly produce area-averaged values of meteorological parameters. As a result consistent data will be obtained for validation of numerical atmospheric micro-scale models. Such a measuring system can complement conventional point measurements o...

Remote turbulence sensing in the first 100m above ground using lunar scintillation has revealed that the seeing measured by regular site monitors can be over-estimated. This explains the well-known discrepancy between the VLT image quality and the seeing measured by the DIMM at Paranal. The concept of ”site seeing” needs to be critically reviewed, considering strong dependence of this parameter...

Depletion of the liquid density near a solid surface with a weak longrange fluid-surface interaction was studied by computer simulations of the liquidvapor coexistence of a LJ fluid confined in slitlike pores. In a wide temperature range the liquid density decreases towards the surface without the formation of a vapor layer between the liquid and the solid surface. This evidences the absence of...

Interest in thick-photoresist applications is steadily growing. In addition to bump fabrication and wire interconnect technology (WIT), the process of patterning thick-layer photoresists by UV lithography is specially qualified for applications in microelectromechanical systems (MEMS). Specialized equipment and new photoresists have been developed or are under development to cope with the new c...

A single-layer, bandpass, active FSS is presented. It shows good angle of incidence stability for TE incidence, at the operating frequency of 2.45 GHz. It is based on circular loop aperture with each unit cell having four PIN diodes. A novel method for dc biasing is used. About 12 dB average variation in transmission loss, between ON and OFF states, has been experimentally achieved at 2.45 GHz.
