The main objective of this paper is to develop PI and Fuzzy controllers to analyse the performance of instantaneous real active and reactive current (id-iq) control strategy for extracting reference currents of shunt active filters under balanced, unbalanced and balanced non-sinusoidal conditions. When the supply volt…
Gas diffusion in nanoporous carbon includes distinct diffusion modes: surface diffusion on the pore walls and non-surface diffusion away from pore walls. We have performed molecular dynamics (MD) simulations of Ar diffusion in disordered nanoporous carbon. The main objective of this work is to separate the surface dif…

Nanosized SiO2 microspheres with an average diameter of 226 nm were synthesized by sol-gel methods. After being modified by silane coupling agent KH-570 and using sodium dodecylsulphate(SDS) as emulsifier, nanosized SiO2 microspheres were fabricated on melamine formaldehyde with ultrasonication, which aimed at weakeni…

Chemical degradation of a refractory lining is most commonly considered as a dissolution process whereby the refractory components dissolve into the liquid slag. Hence, the lining thickness is steadily reduced. The dissolution process is not merely limited to the slag-refractory contact surface, but due to capillary f…

A solution polyaddition procedure was applied to prepare furanic polyacylsemicarbazides based on 2,2′-isopropylidene-bis(5-(2-furoyl) hydrazide) and aliphatic or aromatic diisocyanates. Model compo...
The generalized k-connectivity κk(G) of a graph G was introduced by Chartrand et al. in 1984. In this paper, we introduce the concept of generalized k-edge-connectivity λk(G). For general k, the generalized k-edge-connectivity of a complete graph is obtained, and Nordhaus-Gaddum-type results for the generalized k-conn…
The Ti1.4V0.6Ni and V5Ti9Zr26.2Ni38Cr3.5Co1.5Mn15.6Al0.4Sn0.8 alloys were prepared via an arc-melting method followed by the melt-spinning technique. We systematically investigated the structures and electrochemical hydrogen storage performances of Ti1.4V0.6Ni+20%(mass fraction) ball-milled VTZN composite materials. I…
REHAU has been developing new areas of application for polymer to provide a more hygienic and non-corrosive solution to traditional piping materials.
Abstract : Thermal energy storage (TES) materials absorb transient pulses of heat, allowing for rapid storage of low-quality thermal energy for later use, and effective temperature regulation as part of a thermal management system. This paper describes recent development of salt hydrate-based TES composites at the Air…
본 연구에서는 탄소나노튜브를 물상에서 균일하게 분산시키기 위하여 물에 녹으면서 분자 내에서 자체 도핑이 가능한 새로운 종류의 그래프트 공중합체(PSSA-g-PANI, poly(styrenesulfonic acid-graft-aniline))를 합성하였고, 그 분산 능력을 실험해 보았다. PANI 고분자는 벤조이드와 퀴노이드 구조가 반복되어 존재하는 판상구조로 탄소나노튜브와 같은 탄소나노 소재의 벽에 강하게 결합할 수 있고, 따라서 짧은 시간의 sonication 처리 만으로 나노튜브를 분산시킬 수 있었고 그 분산 용액의 장시간 안정성은 다른 상용화된 분산제보다 뛰어…
Analysis and Applications. interfaces. Experimentally determined values for the dielectric functions of gold and silver are taken from the work of Johnson and Christy.47 When considering only the real part of the propagation constant, the ...
Eisenmenger syndrome differs significantly from other types of pulmonary arterial hypertension in terms of pathophysiology and natural history The type and size of the congenital heart defect in Eisenmenger syndrome is important, as it has physiological and prognostic implications Eisenmenger syndrome is associated wi…
A dynamic reactor model has been developed for pulse-type reactor applications. The model predicts reactor power, axial and radial fuel expansion, prompt and delayed neutron population, and prompt and delayed gamma population. All model predictions are made as a function of time. The model includes the reactivity effe…
A microkinetic chemical reaction mechanism capable of describing both the storage and regeneration processes in a fully formulated lean NOx trap (LNT) is presented. The mechanism includes steps occurring on the precious metal, barium oxide (NOx storage), and cerium oxide (oxygen storage) sites of the catalyst. The com…
