A general parametric nonlinear mathematical programming problem with an operator equality constraint and a finite number of functional inequality constraints is considered in a Hilbert space. Elements of a minimizing sequence for this problem are formally constructed from elements of minimizing sequences for its augme…
Sulfonated cyclohexanone-formaldehyde resin (SCF) was synthesized using cyclohexanone and formaldehyde as raw materials, sodium sulfite as sulfonating agent. The composition of the SCF resin was characterized by FTIR and 13C NMR, and the possible mechanism for formation of the resin was suggested. The effects of react…
Comparing to oil transformer, the dry-type transformer minimizes explosion and fire hazard, as well as long product life. Meanwhile winding insulation plays an important role in the reliability, yet winding temperature rise may cause deterioration to the insulation. So it is critical to have temperature rise analysis…
BiOCl nanosheets were annealed at different temperatures. The effect of annealing on structures and properties was characterized by X-ray diffraction (XRD), N2 adsorption-desorption, UV-visible diffuse reflectance spectroscopy (DRS) and photoluminescence spectroscopy (PL). The photocatalytic performance was evaluated…
Fatigue properties of canopy PMMA with typical damage, which are two different depth scratches of 0.3mm and 0.4mm, are studied by experimental method. In order to gain the fatigue strength about the depth scratches of 0.3mm in the designated life, experiments based on up and down method had been conducted. The S-N cur…
In this work, metamaterial patterns are applied to a GTEM - Gigahertz Transverse Electromagnetic Chamber to improve and give flexibility to its frequency response. The main goal is to achieve a better frequency resonance regardless the dimensions of the original chamber. Therefore, a comparison between the CLL - Capac…
Abstract. This work focuses on the basic suitability assessment of polymeric materials and the corresponding technological methods for the production of infrared (micro-) bolometer arrays. The sensitive layer of the microbolometer arrays in question is composed of an electrically conductive polymer composite. Semi-con…
In the present work, electrospray ionization mass spectrometry (ESI-MS) was used to investigate the titanium clusters present during nucleation and growth of sol-gel derived TiO2 nanoparticles. Depending on the alkoxide precursor used, Ti clusters of different sizes were identified [titanium isopropoxide (TTIP)-11-12…
이 논문은 콜로이드 입자가 기름-물 사이의 계면으로 흡착될 때 필수적으로 존재하는 정전기적 반발력에 대한 실험적, 이론적 연구이다. 광집게(optical laser tweezers)와 피에조(piezo controller)를 사용하여, 개별 입자를 트랩(trap)한 후, 계면으로 강제 전이시킨다. 이때 수용액이 전해질을 포함한 경우에만, 입자가 계면으로 전이되며, 포함하지 않을 경우에는 흡착이 일어나지 않는다. 이러한 현상을 근본적으로 이해하기 위해, 광학 트랩핑 힘(optical trapping force)과 입자와 계면 사이에 존재하는 정전기적 분리압력(elec…
The polycrystalline sample of Li2Pb2Nd2W2Ti4Nb4O30 was prepared by a solid-state reaction technique. Room temperature X-ray structural analysis confirms the formation of a single-phase compound. The morphology of the sintered sample recorded by scanning electron microscope exhibits a uniform grain distribution. Detail…
Oil palm empty fruit bunches (EFB) is one of lignocellulosic natural resource, which is highly potential as adhesive and particleboard raw materials. The purpose of the study was determine wood liquid qualities, and to evaluate the effect of adhesive contents, wood liquid extension levels on melamine formaldehyde (MF)…
Summary The grafting of HDPE and LLDPE with itaconic acid (AIt) was made by reactive extrusion using the peroxide 2,5‐dimethyl‐2,5‐di(tert‐butyli) peroxy hexane (trigonox 101) as initiator. The graft efficiency was evaluated using FTIR to identify bands of carbonyl groups in the polymer. It is influence on the additio…
Epitaxial heterostructures constructed from the thermoelectric cobalt Bi 2 Sr 2 Co 2 O y thin films and SrTiO 3 as well as SrTi 0.993 Nb 0.007 O 3 substrates were fabricated by pulsed-laser deposition. The scanning transmission electron microscopy results confirm that the heterostructures are epitaxial, with sharp and…
The progressive Cu - 5 vol. % Al2O3 nanocomposites were produced from powder prepared by original mechanical-chemical method. Powder consolidation was realized by pressing at two different temperatures (at ambient temperature and 400℃), sintering, forging and extruding. The goal of the work was to compare the influenc…
Five years have passed since the Broader Approach (BA) activities launched in 2007 under the framework of collaboration between Japan and EURATOM. In the International Fusion Materials Irradiation Facility (IFMIF) Engineering Validation and Engineering Design Activities (EVEDA) project, commissioning of the prototype…
The continuous increase of the number of heavy trucks with excessive axle load requires the implementation of new technologies, prolonging the longevity of road pavement. Therefore, Reinforcement grids have recently come into use in pavements in order to retard the distresses in the asphalt surface layers. The main ob…

Influence of isochronal annealing in the range of 350–1100 oC on the structural properties and the intrinsic absorption edge in thin silicon films doped with tin (a-SiSn) has been studied. It is found that as-deposited a-SiSn films with a tin content of about 4 at.%, unlike undoped a-Si ones, contain silicon nanocryst…
