There was made the analysis of wound ballistics modern expansive bullets in comparison with shell on 25 blocks ballistic plasticine (ROMA PLASTILINA No. 1, Ballistic Testing Backing Material), USA, which one shot from an AKS-74 automatic firearm and carbine ZBROYAR Z-10 optical sight fired. The bullet speed highest 5.45x39 caliber cartridge a V-max bullet. – 1185 m/s, low .308 Win SP, 664 m/s. ...

The prominent “1/3” effect observed in the Hall effect plateaus of twodimensional electron gas (2DEG) systems has been postulated to indicating 1/3 fractional charge quasiparticle excitations arising from electron–electron interactions. Tunneling shot-noise experiments on 2DEF exhibiting fractional quantum Hall effect (FQHE) shows evidence for tunnelling of particles with e and e/3 charges for ...

In this work, we present the CoESCA station for electron-electron coincidence spectroscopy from surfaces, built in a close collaboration between Uppsala University and Helmholtz-Zentrum Berlin at BESSY II synchrotron facility Berlin, Germany. We start with detailed overview of previous work field coincidences, before describe setup its design parameters. The system is capable recording shot-to-...

In this paper we propose an innovative combination strategy for a system using video and audio stream of a news video to automatically segment it into stories. In our approach, the segmentation is performed in two steps: first, shots are classified by combining three different anchor shot detection algorithms using video information only. Then, the shot classification is improved by using a nov...

We investigate the injection of degenerate Fermi-Dirac electrons into a multimode ballistic conductor under the space-charge-limited regime. The nonequilibrium current fluctuations were found to be suppressed by both Coulomb and Fermi correlations. We show that the Fermi shot-noise-suppression factor is limited below by the value 2kBT/«F , where T is the temperature and «F the Fermi energy of t...

This paper presents our experiments on TRECVID workshop 2008. This year we participated in two challenging tasks, rushes video summarisation and video copy detection tasks. We studied a spatio-temporal video model to represent inter-frame correlation between two streams of video. The rushes summarisation task is aiming at creation of summaries with length not more than 2% of the original video....

Following the discovery of polyphagous shot hole borer Euwallacea fornicatus (Eichhoff) in Western Australia September 2021, we estimated likely economic damage that will result coming decades and return on investment eradication. A bioeconomic model was used to simulate insect's spread impact based additional urban commercial tree management costs. Two scenarios were examined, one which an era...
