Fabric weight is an important product criterion of woven fabrics. An adequate sensor in order to monitor fabric weight during weav ing is proposed in this paper. In addition, a closed control loop is designed in order to regulate fabric weight during weav ing. After plant identification it is observable that the syste…
Acylation of hydroxyphenylporphyrins by carboxylic acids in the presence of carbodiimides was studied and the optimal reaction conditions were determined. Some new esters of various hydroxyphenylporphyrins were synthesized.
It was demonstrated that various threaded structures could be constructed by employing different esters as end groups based on the benzo-21-crown-7/secondary ammonium salt recognition motif. The chemical structures of all synthesized compounds were confirmed by (1)H and (13)C NMR spectroscopy as well as mass spectrome…
We report on atomic structure imaging of epitaxial L10 CoPt nanoparticles using chemically sensitive high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM). Highly ordered nanoparticles formed by annealing at 973 K show single‐variant structure with perpendicular c‐axis orientation, while…
Three types of carbosilane hyperbranched polymers were studied in dilute solution in toluene. The samples had different lengths of chains between branch points and the structure of terminal groups (butyl, undecenyl, or fluorine containing). The temperature dependences of intrinsic viscosity and second virial coefficie…
In this study, 4-sided rectangular full-size cabinets from 2 types of medium-density fiberboard (MDF; melamine-coated MDF with edge band and uncoated MDF without edge band) were manufactured and tested. Screws with nominal size of 4 × 40 mm were used for joint fabrication. Cabinets were kept in a conditioned climate c…
The microbeam system at Tohoku University was upgraded to a triplet lens system aiming at applying to the analysis of sub-micron features. The triplet lens system has a higher demagnification than the existing doublet system. However, the introduction of the triplet system also resulted in larger chromatic and spheric…
Multilevel Approach in Biodiversity Analysis of Freshwater Algae The relationships between algal biodiversity and environmental conditions are determined by adaptation level of the species and the community as a whole. Bioindication is based on the principal of congruence between community composition and complexity o…
Aluminum oxide based thin films are applied on cutting tool inserts as a top layer to protect the underlying nitride or carbide functional layer from the harsh working environment in terms of abrasive and chemical wear under thermal and pressure load. This Thesis explores the synthesis and characterization of the next…
Many industrial technology equipment produces residual (waste) heat. This heat in the form of combustion allows the use of enthalpy drop for heat recovery and can be used to power other devices, which may partially or completely replace the fuel or energy. Significant limiting factor in the construction of systems for…
Feeding safe and reliable power to mining can be a challenge, with loads depending on secure, high quality power supply. A traditional way to deal with shortcomings in power transmission and distribution is reinforcing the grid by building new lines, or upgrading voltages to higher levels. Such measures, however, are…
Abstract—A novel implementation of aggressive space mapping (ASM) for the automatic layout synthesis of planar metamaterial structures is outlined in this article. Specifically, we employ a model-trust region optimisation approach to significantly reduce the computational burden associated with the direct optimisation…
A large nu mber of currently used synthetic biodegradable polymers in bio med ical engineering applications are polyesters based materials and thus research on the synthesis, properties, manufacturing and processing of aliphatic polyesters continues to be of great importance. Poly -ω-pentadecalactone (PPDL) a lactone…
Although platinum (Pt) is a rare and very expensive material, Pt counter electrodes are still very commonly used for reaching high efficiencies in dye-sensitized solar cells (DSCs). The use of alternative cheaper catalyst materials did not yet yield equivalent efficiencies. In this work, we tried to understand how to…
A nickel-loaded activated carbon (Ni/AC) composite particle electrode was prepared by electroless deposition with palladium-free pretreatment to improve the electrocatalytic performance of a composite particle electrode in a three-dimensional electrode cell. The preparation conditions of the Ni/AC particle electrode w…
Electron beam irradiation, without any addition of cross-linking agents, was investigated at varying doses of EB-Irradiation to develop an environmentally friendly hybridized kenaf (bast)/ pineapple leaf fibre (PALF) bio-composites. Improvement in tensile property of the hybrid was achieved with the result showing a d…
The ternary semiconductor, copper tin sulphide (Cu4SnS4) is considered to be a promising absorber layer in the development of thin film heterojunction solar cells due to its optimu m physical properties. Further, it contained more abundant and cheaper elements that are environ mentally safe to handle. In the present s…
Utilities, cable makers and industry experts generally agree that the results of medium voltage cable qualification testing are a good indication of ultimate cable performance and expected lifetime. Here we focus on the development of a new enhanced cable insulation material for distribution cables. While qualificatio…

The spreading dynamics of a water droplet on a soluble polymer substrate is controlled by the rate of water transfers into the substrate. We provide a comprehensive description of the parameters controlling the wetting dynamics based on the analysis of the transfers between the spreading liquid and the solid substrate…
