The purpose of this gaper is to analyze and detect changes in body position (BPC) during electrocardiogram (ECG) recording. These changes are often manifested as shifts in the, electrical axis and may be misclassified as ischemic changes during. ambulatory monitoring. We investigate two ECG signal processing methods for detecting BPCs. Different schemes for feature extraction are used (spatial and
This thesis investigates if it is possible to measure the plunger position in a Ledex 282352-023 solenoid actuator without the use of external sensors. To do this, various different methods, all based on comparing the current response to the applied voltage were evaluated from different categories such as calculation time, reliability and distinct position levels. The method that performed best in
Spin crossover (SCO) complexes are highly promising candidates for a myriad of potential applications in room-temperature electronics; however, as it stands, establishing a clear connection between their spin-state switching and transport properties has been far from trivial. In this perspective, an effort to unravel the underlying charge transport mechanism in these SCO complexes, via a general t
The state of water in aqueous microemulsion droplets in the system AOT/D2O/isooctane has been investigated by 2H and 17O NMR. Longitudinal relaxation rates are reported as a function of droplet size, droplet volume fraction, temperature, and resonance frequency. We conclude that the surface-induced perturbation of water rotation is of short range (limited to the primary hydration of the AOT head g
In this talk an interface is presented between the multi-purpose next-to-leading-order Monte Carlo tool MADGRAPH5-AMC@NLO and the automated one-loop amplitude generator GOSAM. As a phenomenological application of this work, the interface is used to make predictions for the ttH and ttgg processes at the 13 TeV LHC. The differences between these two processes is studied, focussing in particular on o
Mn5Ge3(001) thin films grown on Ge(111) were studied by angle-and spin-resolved photoemission using synchrotron radiation in the 17-40 eV photon energy range. The photoelectron spectra were simulated starting from a first-principles band-structure calculation for the ground state, using the free-electron approximation for the final states, taking into account photohole lifetime effects and k(perpe
High-spin states in Cs-123 were populated in the Ni-64(Ni-64,p4n) reaction at a beam energy of 265 MeV. Gamma-ray coincidences were measured using the Gammasphere spectrometer. Two additional bands have been placed in the level scheme and the four previously known bands have been extended to higher spin. At the highest spins, two of the bands show irregular level sequences. These structures of non
We report on a low-temperature magnetoconductance study to characterize the electrical and spin transport properties of n-type InAs nanowires grown by chemical beam epitaxy. A gate-controlled crossover from weak localization to weak antilocalization is observed. The measured magnetoconductance data agrees well with theory for one-dimensional quasi-ballistic systems and yields a spin relaxation len
X-ray absorption and magnetic circular dichroism spectra of as-deposited and postannealed Fe50 Pt50 /C granular multilayers were measured at both the Fe and Pt L2,3 edges. We demonstrate that the partial L 10 ordering of the FePt nanoparticles induced by thermal annealing results in an increase of the effective spin magnetic moments by 200% at the Fe site and by 65% at the Pt site, while the orbit
Part of the Sound Studies Lecture Series NIKOLAOS GEORGIOS VARDAXIS Acoustics refers to the science of sound, its properties and propagation, while the same term is often used to refer to sound qualities of an environment, an indoor space or somewhere outdoors. This lecture offers an introduction to basic acoustic concepts such as sound pressure levels, which is the most essential quantity when de

Self-consistent dynamics of non-homogeneous fluctuations and homogeneous and isotropic condensate of Yang–Mills fields was investigated in zero, linear and quasilinear approximations over the wave modes in the framework of N = 4 supersymmetric model in Hamilton gauge in quasiclassical theory. The models with SU(2), SU(3) and SU(4) gauge groups were considered. Particle production effect and effect
Scaffold hybridization of several natural and synthetic anticancer leads led to the consideration of indenoindolones as potential novel anticancer agents. A series of these compounds were prepared by a diversity-feasible synthetic method. They were found to possess anticancer activities with higher potency compared to etoposide and 5-fluorouracil in kidney cancer cells (HEK 293) and low toxicity t
Non-destructive testing (NDT) is a vital part of aerospace manufacturing due to high demands for quality and safety. Advances in materials science have given rise to aerospace composites with highly improved properties compared to traditional materials. To ensure that materials can be used safely, NDT techniques are continuously improved to follow advances in materials. This has also spurred devel
