Collecting airborne and spaceborne intelligence, surveillance, reconnaissance (ISR) information is mandatory for addressing the defense challenges posed in 21st century. A key tool increasing content of ISR using advanced electrooptical devices, including hyperspectral imaging (HSI). This optical sensing technology offers high spectral resolution covering visible to long-wave infrared (LWIR) wavelengths. The increase degrees freedom create a unique opportunity detect difficult targets at...
Abstract The tokamak à configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system address critical issues in preparation for ITER a fusion power plant. For the 2019–20 campaign configurational flexibility has been enhanced with installation of removable divertor gas baffles, diagnostic capabilities an extensive set upgrades new dual frequency gyrotrons. baffles reduce coupling between main chamber allow detailed...
Abstract Partitioned fluid–structure interaction simulations of the arterial system are difficult due to incompressibility fluid and shape domain. The interface artificial compressibility (IAC) method mitigates constraint by adding a source term continuity equation in domain adjacent interface. This imitates effect structure's displacement as result pressure disappears when coupling iterations have converged. IAC requires small modification flow solver but not black‐box structural it...
Abstract Fluid–structure interaction simulations can be performed in a partitioned way, by coupling flow solver with structural solver. However, Gauss–Seidel iterations between these solvers without additional stabilization efforts will converge slowly or not at all under common conditions such as an incompressible fluid and high added mass. Quasi-Newton methods then stabilize accelerate the iterations, while still using black boxes only accessing data fluid–structure interface. In this...
We present a new quasi-Newton method that can solve systems of equations which no information is known explicitly and requires special structure the system matrix, like positive definiteness or sparseness. The builds an approximate Jacobian based on input-output combinations black box system, uses rank-one update this after each iteration, satisfies secant equation. While it has originally been developed for nonlinear we analyze its properties performance when applied to linear systems....
Gas Chromatography coupled with Ion Mobility Spectrometry (GC-IMS) is a dual-separation analytical technique widely used for identifying components in gaseous samples by separating and analysing the arrival times of their constituent species. Data generated GC-IMS typically represented as two-dimensional spectra, providing rich information but posing challenges data-driven analysis due to limited labelled datasets. This study introduces novel method generating synthetic 2D spectra using deep...
This study aims to measure and compare spatiotemporal gait parameters in nineteen subjects using a full wearable inertial mocap system Xsens (MVN Awinda, Netherlands) photoelectronic one-meter OptoGaitTM (Microgait, Italy) on treadmill imposing walking speed of 5 km/h. A total eleven steps were considered for each subject constituting dataset 209 samples from which (SPT) calculated. The step length measurement was determined two methods. first one considers the calculation based inverted...
We show how one of the best-known Krylov subspace methods, generalized minimal residual method (GMRes), can be interpreted as a quasi-Newton and inverse least squares (QN-ILS) relates to methods in general GMRes particular when applied linear systems. also that we modify QN-ILS order make it analytically equivalent GMRes, without need for extra matrix-vector products.
The increasing risks of border intrusions or attacks on sensitive facilities and the growing availability surveillance cameras lead to extensive research efforts for robust detection pedestrians using images. However, borders poses many challenges including need set up cover whole area interest, high bandwidth requirements data streaming high‐processing requirements. Driven by day night capabilities thermal sensors distinguished signature humans, authors propose a novel method is composed...
Firefighting is a crucial part of the Navy's training program, as it must ensure safety on board. This dangerous, expensive and environmentally unfriendly. Therefore, Navy looking for safer form that can enhance current one. Extended Reality technology offers new ways training, with promise to alleviate issues related danger, costs environmental pollution. In this work, we develop evaluate Virtual simulator proof concept Mixed simulator, together firehose controller adapted needs...
