The objectives of this study were to investigate the sound characteristics of combat uniform fabrics and to provide the condition for arousing positive sensibility by measuring psychological sensation for the frictional sound of the fabrics. The frictional sounds of six combat uniform fabrics were generated by the Sim…
We perform quantum Monte Carlo calculations to determine how the Renyi entropies, $S_n$, of the interacting Fermi liquid depend on Renyi order, $n$, and scale as a function of system size, $L$. Using the swap operator and an accurate Slater-Jastrow wave function, we compute Renyi entropies for spinless fermions intera…
Because bamboo charcoal is known to have high porosity, it is widely used in those products which has good qualities for keeping the room environment comfort for example the wall material, the formed panel, and so on. So far, however, there is no research that evaluated the effectiveness of this material to the comfor…
The critical behavior of a two-orbital model with degenerate $d_{xz}$ and $d_{yz}$ orbitals is investigated by multidimensional bosonization. We find that the corresponding bosonic theory has an overdamped collective mode with dynamical exponent $z=3$, which appears to be a general feature of a two-orbital model and b…
Organisers of the Great Yorkshire Show in Harrogate will offer to reimburse the trade stand holders for the two days they lost as a result of the ...

Magnetic ferrites are a group of technologically important magnetic materials. Synthesis of nanocrystalline spinel ferrite has been investigated intensively in recent years due to their potential applications in high-density magnetic recording, microwave devices, and magnetic fluids In this study, NiFe2O4 nano particl…
[ANGLES] In the present work we have grown ZnO nanowires over different substrates by the vapour-liquid-solid growth method, changing several growth parameters, such as the Au sputtered thin layer, temperature, pressure and gas flow. We have characterized their optical properties measuring the optical absorption and p…
Η παρούσα εργασία μελετά υπάρχουσες και εναλλακτικές τεχνικές ρύθμισης της τάσης και του συντελεστή ισχύος σε υποσταθμους υψηλής τάσης/μέσης τάσης και γίνεται σύγκριση τους ως προς το πως επηρεάζουν τη μέγιστη μεταφερόμενη ισχύ σε ένα ακτινικό δίκτυο. Μηχανισμοί που μελετώνται είναι μετασχηματιστές με ΣΑΤΥΦ, εγκάρσιοι…
Nuclear grade (high-purity) graphite for fuel element and moderator material in Advanced Gas Cooling Reactors (AGR) displays large scatter in strength and a non-linear stress-strain response from the damage accumulation. These responses can be characterized as quasi-brittle behaviour. Current assessments of fracture i…
My project explored the impact of temperature and annealing on the optical constants of La0.67Sr0.33MnO3 (LSMO) films grown on a lanthanum aluminate (LAO) substrate. This was done with infrared and optical spectroscopy, which allows us to measure the complex dielectric function of the material. Both the substrate and…
Copper(I) iodide and other copper(I) salts (CuX) react with amines and sulfides (L) in their gas phase to form luminescent rhomboid Cu2(μ2-X)2L4 and/or cubane Cu4(μ3-X)4L4 complexes. This work reports this spontaneous reaction occuring at the surface of CuI powder, pressed CuI pellets, CuI-impregnated polymer films, a…
Many qualitative observations on the glass transition in classical fluids are well described by the mode coupling theory (MCT) but the extent of the non-ergodicity domain is often over-estimated by this theory. Making it more quantitative while preserving its microscopic nature remains thus a current challenge. We pro…
Kebutuhan akan material yang memiliki sifat yang sesuai akan kebutuhan, telah mendorong perkembangan teknologi bahan dengan sangat pesat. Salah satunya adalah komposit. Seiring dengan perkembangan teknologi material komposit, berkembang pula teknologi pengujian kekuatan mekanik material. Dimana pada saat ini pengujian…
We present a study of the effects of fabrication tolerances on the performance of a planar array of double-sided split-ring resonators, printed on two sides of a dielectric substrate and fabricated using a printed circuit board (PCB) milling machine. The array is simulated and measured in an X-band waveguide, and the…

Daten- und Informationsverarbeitung via Quantencomputer ist ein viel versprechender Ansatz, um die klassische Art und Weise via Digitalrechner, welche sich fundamentalen physikalischen Grenzen annShern, zu ersetzen. Anstelle von klassischen Bits werden Quantenbits (Qubits) fŸr Rechenoperationen verwendet. Aufgrund qua…
This study was aimed to investigate if visual texture could be affected by color variables such as CIE values and hue/tone categories as well as mechanical properties of fabrics and to establish prediction models for fabric visual texture using both mechanical properties and color variables. Six different silk and cot…
