With the I-type plastic extrusion die for example, the advantages and disadvantages between the traditional design method and optimization design method were compared. The design was studied via finite element numeric analysis combined with optimization, whose objective was the equal average flow velocity of each sub-…
This study aims to find out the best anode location for buried pipelines. Numerical simulation program known as CATPRO(Elsyca, Belgium) were used for confirming the best location of anodes and the effects of impressed current cathodic protection system. Applied conditions for numerical simulation were similar to on-si…

The aim of this study was to measure the functional properties of a nanofiber web laminate, microporous film laminate, and nonporous coating fabric and then compare their performances as a breathable waterproof fabric. We focused on the performance of the nanofiber web laminate as a breathable waterproof fabric. A PU…
The paper proposed an innovative shape memory alloy (SMA)-friction damper. The damper consisted of the superelastic SMA wire and the friction element in series. According to the working mechanism of the damper, the paper set up the mechanical model of the damper. Seismic elastic-plastic time history response analysis…
By using computational fluid dynamics and chemical reaction dynamics method, the mathematical model of SCR (selective catalytic reduction) system was established. On the basis of the verified feasibility, by CFD numerical analytical method, the reducing agent inside the catalysts concentration distribution was compare…
본 연구의 목적은 도로에서 발생하는 파손과 이로 인한 피해를 예방하기 위해, 도로의 수명증진시킬 수 있는 자기치유형 아스팔트(Self-Healing Asphalt) 혼합물의 개발하고 그 특성을 파악하는 것이다. SHA아스팔트 혼합물의 특성을 파악하기 위해 일반 가열 아스팔트(Hot Mixed Asphalt)혼합물과 비교하여 동하중시험과 간접인장강도시험을 수행하였다. 자기치유형 아스팔트 혼합물은 SBS(Strene Butadiene-Styrene triblock copolymer)고무와 벤조페논으로 구성된 마이크로캡슐을 이용하여 제작되었다. 간접인장강도시험을 수행하는…

NdFeB bonded magnets are produced by compression molding and curing. Typical raw materials are mixtures of epoxy resin and Nd2Fe14B flakes, produced mostly by melt spinning. The curing temperature should be adjusted for obtaining the best in terms of mechanical properties without overheating the pressed component. Hig…
First results of a possible alternative route for plasma assisted processing of 410 LHC steel powder compacts are shown in present work. Carburizing treatment was performed simultaneously with the sintering of samples. The main motivation of this study was verifying the possibility to eliminate the manufacturing step…
The glass used for mobile display windows is required to have high strength. Chemical strengthening by means of ion exchange is widely used glass. The depth of the layer and the compressed stress are affected by tempering temperature and time. The purpose of this study is to investigate the range of DOL and CS, which…
—The necessity of using a 3D model is one of the main problems for modeling Roebel bar transposition in turbo-generators by the finite-element method. This article proposes a 2D dual model for computing strand current distribution in the Roebel bar of turbo-generators. Considering the leakage and mutual inductances fo…
The main aim of this work is to show porosity evolution during application of various processing conditions to a high-purity (99.7 wt.%) iron powder, including compacting, sintering and equal channel angular pressing (ECAP). Iron powder bars with dimensions of 8x8x30 mm and 8x8x10 mm were axially pressed with pressure…
Functionally graded materials (FGM) based on stainless steel and ceramic materials have inspired researchers to combine properties and features which are not present in conventional composites, and are considered to be an alternative in the production of motors parts, cutting tools and coatings for reactors. The addit…
The milling process of elemental Ti-2Ta-22Si-11B and Ti-6Ta-22Si-11B (at-%) powder mixtures were performed in a planetary Fritsch P-5 ball mill using stainless steel vials (225 mL) and hardened steel balls (19 mm diameter). Ball-to-powder weight ratio of 10:1 and a rotary speed of 300 rpm were adopted, varying the mil…
The purpose of this research is to prepare basic data necessary to develop uniform design by examining the uniforms of Korean and Chinese airline crew. Advanced research, various literature materials related to uniform, as well as a survey on the images portrayed by the different uniforms of the airlines were used as…
AbstractPERFORMANCE OF TWO TYPES OF CEMENT IN PRODUCTION OF CEMENT BONDED WOOD PANELS COMBINED WITH RICE HULLThe objective of this study was to evaluate the performance of two types of cement in the manufacturing of cement bonded wood panels with addition of rice hull. Sealers used were cement V-ARI (CP V) and cement…
The dysprosium-diffused Nd2Fe14B magnets are a feasible way to increase coercivity and saving dysprosium at the same time. In the practice, a dysprosium source layer is placed over a NdFeB magnet substrate, and Dy diffusion takes place from the surface to the center of the substrate. This practical situation is modele…
The system for producing magnetic field constitutes an important component of magnetic refrigerator. Many researchers have directed significant effort to increase the magnetic field intensity, because the magnetocaloric effect at the Curie temperature increases with the power of 2/3 of the magnetic field. In this stud…
