Abstract DarkSide-20k (DS-20k) is a dark matter detection experiment under construction at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It utilises ∼ 100 t of low radioactivity argon from an underground source (UAr) its inner detector, with half serving as target dual-phase time projection chamber (TPC). The UAr cryogenics system must maintain stable thermodynamic conditions throughout experiment's lifetime over 10 years. Continuous removal impurities and radon essential for...
For most wild animals, the peak activity occurs during night hours—their observation is possible only with use of specialized equipment. Advancements in technology and availability thermal sensing devices allow researchers to examine wildlife. This study compares different methods for animal detection camera images including classical (HOG/SVM) based on deep neural networks (Faster RCNN YOLO). A comparison was performed indicate beneficial mean Average Precision (mAP) levels Intersection...
We present HoloFace, an open-source framework for face alignment, head pose estimation and facial attribute retrieval Microsoft HoloLens. HoloFace implements two state-of-the-art alignment methods which can be used interchangeably: one running locally on a remote backend. Head is accomplished by fitting deformable 3D model to the landmarks localized using alignment. The provides both rotation of position in world space. parameters fitted provide estimates attributes such as mouth opening or...
Experiments aimed at direct searches for WIMP dark matter require highly effective reduction of backgrounds and control any residual radioactive contamination. In particular, neutrons interacting with atomic nuclei represent an important class due to the expected similarity a WIMP-nucleon interaction, so that such experiments often feature dedicated neutron detector surrounding active target volume. context development DarkSide-20k INFN Gran Sasso National Laboratory (LNGS), several R&D...
The dual-phase liquid argon time projection chamber is presently one of the leading technologies to search for dark matter particles with masses below 10 GeV/c$^2$. This was demonstrated by DarkSide-50 experiment approximately 50 kg low-radioactivity as target material. next generation DarkSide-20k, currently under construction, will use 1,000 times more and expected start operation in 2027. Based on experience, here we assess DarkSide-20k sensitivity models predicting light particles,...

Hyper-Kamiokande is the next generation underground water Cherenkov detector that builds on highly successful Super-Kamiokande experiment. The which has an 8.4~times larger effective volume than its predecessor will be located along T2K neutrino beamline and utilize upgraded J-PARC beam with 2.6~times power. Hyper-K's low energy threshold combined very large fiducial make unique, expected to acquire unprecedented exposure of 3.8~Mton$\cdot$year over a period 20~years operation. combines...
Novel motion trajectory representations are introduced for efficient storage, transmission and search. Bit size reducing is obtained by specialization of temporal models to each spatial coordinate contrary MPEG-7 approach where the same all dimensions. On trajectories experimentation model (XM) average bit gain about 17%. For matching in search applications, proposed similarity measure based on exact integral formula piecewise polynomial representation. This not only more accurate but at...
Detection of characteristic eye points under challenging light conditions is a non-trivial task. Difficulty this task increase even more when low resolution images are used. This article introduces an adaptive solution for detection in mentioned conditions. First, normalization algorithm performed. Then, face and followed by determination status (namely: open or closed) done. Finally, method pupil corners developed comparing some existing methods. Experimental results show the outperformance...
The framework for testing video streaming techniques is presented in this paper. Short review of error resilience and concealments tools available the H.264/AVCstandard given. protocols H.264 payload format are also described. experimental results obtained with paper too.
Abstract The paper presents experimental results for the detection of related video streams (views) multi camera system using MPEG-7 visual signature tools. This can be used identification stored in repositories which constitute same recording set. Two tools have been investigated: Image Signature descriptor and Video descriptor. motivation usage designed primarily replica is fact that material produced by typically consists a few are similar to each other and, thus, regarded as...
