In order to efficiently detect defect for a fabric image with complex texture and variety of defects,this paper proposed a novel defect detection algorithm based on local statistical features and global saliency analysis.In the proposed algorithm,the target image is firstly divided into blocks with the same size,then…
In order to study and predict the formation process of the serrated chip in high-speed cutting( HSC),a finite element model of the high-speed cutting of superalloy was constructed by using the finite element analysis software ABAQUS. By the adoption of the Johnson-Cook thermal visco-plastic constitutive model,the sepa…
An X-ray spectrum measured with CdTe detector has to be corrected with response function, because the spectrum is composed of full energy peaks (FEP) and escape peaks (EP). Recently, various simulation codes were developed, and using them the response functions can be calculated easily. The aim of this study is to pro…
Recently, high-strength steels with over 1500 MPa in tensile strength have been manufactured by hot stamping.To decrease their coefficient of friction, the effects of die surface coating on such a parameter were investigated.The Five kinds of die coated with TiN, TiCN, CrN, TiAlN, and DLC-Si were used.The experimental…
, CuTPP were prepared by conventional thermal evaporation technique on p-Si substrates to form CuTPP/p-Si organic-inorganic hybrid hetrojunction. The temperature-dependence of the electrical characteristics of the CuTPP/p-Si heterojunction in the temperature range of 298-353 K was studied. The barrier height and ideal…
高耐食性Ti添加フェライトステンレス鋼において，Ti炭窒化物が孔食の起点となり得ると報告されてきた．しかし，Ti炭窒化物に関する孔食発生前後の観点での観察例はほとんどない．そのため，Ti炭窒化物周辺の孔食発生挙動の理解は未だ不十分である．そこで本研究は，定電位型溶液中AFM観察を行うことによりTi炭窒化物周辺の孔食発生挙動を明らかにすることを目的とした．その結果，圧延や研磨によりTi炭窒化物 / 素地境界に形成された深さ数十nm，幅数百nmのすき間を起点に孔食が発生することを明らかにした．そして時間の経過と共に，孔食は素地側の深さ方向に進展した．
In our present stage, metal matrix composite is more acceptable because they are suitable for applications requiring combined strength and thermal conductivity, damping properties, lower density. The properties of MMCs enhance their usage in automotive and many applications. In the field of automobile, MMCs are used f…
ノリの色落ち原因珪藻 Asteroplanus karianus の出現動態と環境要因との関係を調べるため，2007 年 12 月から 2012 年 3 月に有明海佐賀県海域で，植物プランクトン組成および各種環境要因を調査した。また，高水温および低水温条件下における本種の増殖および発芽特性を室内試験で調べた。その結果，本種は冬季にのみ赤潮を形成することが確認された。また，本種の増殖速度は低水温よりも高水温条件下で高いことが確認されたが，底泥中の休眠期細胞が発芽に要する時間は低水温条件下で短いことが示唆された。
In this paper, the molecular array behavior of anionic surfactant sodium dodecyl sulfate SDS and zwitterionic surfactant Betaine at the air/water and oil/water interfaces were investigated by molecular simulation approaches, which helped to understand the effects of temperature, salts and the proportion of components…
In this study a novel type of EDTA-Surface functionalized Si-coated magnetite nano particles were synthesized. Being hexadentate ligand EDTA (ethylene-di-ammine tetra acetic acid) has a higher rate of chelation or complication with toxic metals thus enhancing the removal efficiency of nanosorbents. Magnetite nanoparti…
The work is dedicated to EMF attraction processes which can deform both ferromagnetic and non-ferromagnetic sheet metal materials (low carbon steels, stainless steels and aluminum alloys) using low frequency discharges. The analytical models of both tooling configurations are based upon the solution of Maxwell equatio…
Presents all-new laboratory-tested theory for calculating more accurate ionized electric fields to aid in designing high-voltage devices and its components Understanding and accurately calculating corona originated electric fields are important issues for scientists who are involved in electromagnetic and electrostati…
The movement of Cu in a HfO 2 -based resistive random access memory (RRAM) device is investigated in depth by first-principle calculations. Thermodynamics analysis shows that the dominant motion of Cu tends to be along the [001] orientation with a faster speed. The migration barriers along different routes are compare…
Decellularization provides low immunogenicity and is only slightly subject to calcification in tissue engineering. However, the mechanical properties of the tissues are weakened after decellularization. We adopted cross-linking agent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) to treat decellularized porcine…
The current paper focuses on development of a method for studying micro-scale strains on the microstructure of ferritic cast iron. For this purpose, in-situ tensile tests were done under the optical microscope combined with digital image correlation (DIC). Critical in this development was to be able to achieve a relia…
Using Co-Mo/MgO catalyst, single walled carbon nanotubes with a diameter of 2 nm and a length of 10 µm were produced by chemical vapor deposition process and characterized by XRD, FTIR and SEM. Synthesized single-walled carbon nanotubes were dissolved in water to make a 1 w% solution and stabilized by adding sodium do…
