This document summarises the main changes to ATLAS experiment’s Inner Detector Track reconstruction software chain in preparation of LHC Run 3 (2022-2024). The work was carried out ensure that expected high-activity collisions with on average 50 simultaneous proton-proton interactions per bunch crossing (pile-up) can be reconstructed promptly using available computing resources. Performance fig...

Inspired by the discovery of dimeric motor proteins capable of undergoing transportation in living cells, significant efforts have been expended recently to the fabrication of track-walking nanomotors possessing two foot-like components that each can bind or detach from an array of anchorage groups on the track in response to local events of reagent consumption. The central problem in fabricati...

Rates of revision surgery due to deep infection following total hip arthroplasty (THA) increased at a Norwegian hospital following implementation of fast-track procedures. The purpose of this study was to determine whether selected demographic (age and sex) and clinical (body mass index, American Society of Anesthesiologists (ASA) classification, surgery duration, length of hospital stay, cemen...

This paper proposes a novel merging algorithm in Gaussian mixture probability hypothesis density filter to track close proximity targets. The proposed algorithm is added after GM-PHD recursion, in a condition that more than one target has the same state. The weights of Gaussian components decide whether the components can be utilized to extract states, and the means and covariances of Gaussian ...

Shoulder stability depends on the position of the arm as well as activities of the muscles around the shoulder. The capsulo-ligamentous structures are the main stabilisers with the arm at the end-range of movement, whereas negative intra-articular pressure and concavity-compression effect are the main stabilisers with the arm in the mid-range of movement.There are two types of glenoid bone loss...

The problem of real-time object tracking in live video sequences is of increasing importance today mainly due to higher security requirements for surveillance applications. In this study we present a novel particle swarm optimization (PSO) algorithm with additional new features. The basic idea of PSO is to use one swarm or one hierarchical swarm of particles to find the best estimate or the glo...

This report describes the performance prediction models for the passive narrowband (PNB) and passive broadband (PBB) automated detection (AD) modes of ARCI and APB 1. Ideal lower bounds on detection performance are formally derived for known target bearings and frequencies. These results are used later in the report to bound the range of detection degradation for estimated target tracks. The mo...

In this paper, we propose the specific recursion formula for generalized labeled multi-Bernoulli filter based on track-before-detect strategy (GLMB-TBD) using a belief propagation algorithm. The proposed method aims to track multiple weak targets with superior performance. Compared Murty algorithm-based and Gibbs sampling-based implementation of GLMB-TBD filter, algorithm improves tracking accu...

The detection and identification of Resident Space Objects (RSOs) from survey tracks requires robust efficient orbit determination methods for the association observations same RSO. Both Initial Orbit Determination (IOD) (OD) perform orbital estimation in which relies. choice proper IOD OD is essential whole data association, since they are charge providing required to evaluate figure merit ass...
