In order to perform parametric study on advanced combustion process in diesel engines, zero-dimensional diesel spray model is needed to predict the diesel spray propagation including the spray evolution after end-of-injection (EOI) with varying injection rate. In this study, a previous phenomenological spray model inc…
The physiochemical characteristics of soot particles such as oxidative reactivity and volatile organic fraction (VOF) are of importance with regard to performance of diesel after-treatment systems and the health hazards. Such characteristics depend on the engine operating conditions, as mixture formation and temperatu…
融液成長中の Si 単結晶において固液界面近傍に発生する異方性熱応力は，育成する結晶直径の増加に伴い，Grown-in 欠陥の制御性に大きな影響を及ぼす．直径 300 mm の Si 結晶育成時における真性点欠陥の挙動に対する，この異方性熱応力の効果を，計算と実験の両面より調査した．また，この育成結晶に負荷される熱応力の大きさを，ヤング率と絡めて議論する．
The present study describes effects of the surface finishing condition by cutting on tribological properties of aluminum cast alloy. The testing surface was finished with various cutting speed with large lake face angled mono crystalline diamond tool tip using a CNC machining center. It was found that the exposed Si p…
Poli(p-fenileno de tereftalamida) (PPTA), usualmente chamado de aramida, é uma fibra polimérica de baixa densidade que possui alta rigidez e resistência à tração, assim como excelente estabilidade térmica e química. Essa fibra é utilizada como reforço em materiais compósitos utilizados nas indústrias aeroespacial e au…
In this paper, the water wave metamaterial is studied to realize the negative refractive index. Shallow water waves propagating to the water channel are analogized to electric waves flowing through the distributed constant circuit, and thus the circuit theory based approach is extended to water waves. We propose the d…
The present work nondestructively observed the dual-phase microstructure of Ti-6Al-4V using synchrotron radiation micro-CT imaging at Spring-8 to establish a nondestructive inspection method which clarifies microstructural effect on the internal fatigue fracture. An imaging system with a small pixel size of 0.23 μm/pi…
In general, Nuclear Power Plants (NPPs) are designed for a postulated earthquake event. Two conceptual stress limits which are Primary stress limit and Primary plus Secondary stress limit are required to meet in the design codes for seismic loads on essential structures such as a piping induced by the seismic event. T…
Elektrochemische Doppelschichtkondensatoren, deren Vertreter in dieser Arbeit behandelt werden, nehmen in Sachen Leistungsfähigkeit, Energiespeicherungsvermögen und Lebensdauer eine Zwischenstellung zwischen den klassischen dielektrischen Kondensatoren und den Batterien ein. Dementsprechend schaffen sie eine vielversp…
Objective: This study was designed to evaluate the effect of various types of Hydroxyapatite, Nano- hydroxyapatite, Micro-hydroxyapatite and mixed hydroxyapatite particles as a bone substitute in the treatment of experimental induced surgical defects around dental implants. Materials and methods: Eight healthy adult m…
Pipe wall thinning is an important issue for aging management of nuclear and fossil power plants. The Japan Society of Mechanical Engineers (JSME) published a guideline on pipe wall thinning management in 2005 and management codes in 2006, which is based on inspection using UT. In JSME, research committee for the impr…
A design study of an advanced sodium-cooled fast reactor (Advanced-SFR) has been conducted in Japan Atomic Energy Agency (JAEA). Hot sodium from the fuel subassembly can mix with the cold sodium from the control rod (CR) channel and the blanket assemblies at the bottom of Upper Internal Structure (UIS). Temperature fl…
Current estimations show hydrogen production to be in excess of 55 million tonnes annually. With consumption growing globally by six percent annually, new feedstocks such as ammonia need to be explored to meet demand. Ammonia has many attractive characteristics as a source for hydrogen, such as its product stream when…
This thesis is about synthesizing polyurethane (PU) solution. The purpose of conducting this research are to prepare a polymer nanofibers using electrospinning technique. Electrospinning is the technique of nanofabrication of polymer nanofibers. The synthesization of the solution is dissolved in N,N-dimethylformamide…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
Acknowledging that the optical properties of noble metal nanocrystals (NMNCs) are largely determined by their size, composition, and shape, the demand for NMNCs with controlled shapes is expected to increase. To expand the property discovery and application development of polyhedral NMNCs, it is pivotal to understand…
Materials for Chang (2018, "Perceptual attention as the locus of transfer to nonnative speech perception", Journal of Phonetics), which are shareable publicly according to the study's IRB protocol. Each of the five listener groups completed a similar language background questionnaire as part of their participation in…
Theoretical and experimental studies show that graphene nanoribbons (GNRs) can possess intriguing physical properties, such as a tunable electronic bandgap and a peculiar magnetic ordering for certain types of nanoribbon edges. However, in order to realize these properties, GNRs should be synthesized with atomic preci…
An increase in the cholesterol content in phospholipid bilayer membranes is known to engender high order structures of lipids, which involve straightened (extended) lipid acyl chains. Lipid rafts are rich in such extended chains and considered to help clustering/multimerization of transmembrane helical peptides. Our r…
