Abstract:
This study, with experiments and comparisons, aims to analyze the difference of stainless (SUS316L) microtubes in the flaring forming among dies with various semicone angles (35°, 40°, 45°, 50°, and 55°). The flow rule by Prandtl-Reuss combined with the finite element deformation theory and updated Lagrangian formulation (ULF) is applied to establish the finite element analysis equation for an incremental elastoplastic deformation to simulate the microtube flaring process. The broadrminalgorithm is utilized in the forming process for the elastoplastic state and die contact. The simulation data

Abstract:
The thermogravimetric method was applied to study the combustion characteristics of waste plastics and semicoke mixture at different heating rates with temperature ranging from room temperature to 1173 K. Also, the kinetic parameters of combustion process were also estimated by fitting the experimental data to the calculated data. The results showed that the mixed combustion process of waste plastics and semicoke could be divided into volatile combustion stage and fixed carbon combustion stage. The addition of waste plastics could increase the comprehensive combustion characteristic index (S)

Abstract:
The thermal behavior of coal tar refined soft pitch (CTRSP) was investigated by using polarizing microscope with heating stage and thermogravimetric analyzer. The phenomena of carbonization regime process of CTRSP were observed directly in the micro-picture taken online. The results showed that the carbonization thermal dynamic process of CTRSP is divided into several typical stages. At 30-250°C,there is small molecular evaporation; at 250-390 °C,there is thermal decomposition and small molecular evaporation; at 390-480°C,there is the condensation of small molecules and radicals into macromole

The decay of feudal relations and intensification of commodity production is analysed on the basis of compulsory inventories in the middle of the 19th century. The basis of agricultural economy in Llthuania was the farm estate, based on corvey work in the Vilnius and Dysna districts, complete corvey work prevailed. Peasants, who paid money for the ground, accounted for 9%, and semicorvey peasants was about 15% ofthe total number of serfdom farms. This state of things showed, that the state was not indined to abolish serfdom at this time.

Abstract:
Continuous sugar centrifugal is used to separate sugar and molasses from massecuite. The centrifugal basket is pierced with numerous holes to allow the molasses to escape and is lined with metal gauze, which serves to retain the sugar while allowing the molasses to pass through. The centrifugal basket is conical in shape (Fig. 1), runs at a constant speed in the range 1200 to 2200 rpm., and is fed by a continuous stream of material. The semicone angle α varies from 25 deg to 35 deg. What prompted this investigation is a fairly high level of working stress experienced in commerically available

Abstract:
We start by investigating the arising of a spin-orbit coupling and a Darwin-type term that stem from Lorentz symmetry breaking effects in the CPT-odd sector of the Standard Model Extension. Then, we establish a possible scenario of the violation of the Lorentz symmetry that gives rise to a linear confining potential and an effective electric field in which determines the spin-orbit coupling for a neutral particle analogous to the Rashba coupling [E. I. Rashba, Sov. Phys. Solid State 2, 1109 (1960)]. Finally, we confine the neutral particle to a quantum dot [W.-C. Tan and J. C. Inkson, Semicond

Metallurgical fuel, including various types of mineral fuels: coke, hard coal, brown coal, peat, combustible shales and products of their technological conversion – needs environmental control of their use safety. When burning metallurgical fuel, harmful substances fall into the environment such as chlorine, fluorine, sulfur, arsenic, which worsen the environmental situation. Technical regulations on the safety of coal products contain requirements to limit the content of harmful impurities and their maximum permissible concentrations.

Thermal management for white LEDs at the encapsulant level is an important task to ensure that the device can operate at a high optical and color performance. In this study, a steady-state thermal model was built wherein the finite element method was employed using MATLAB software to identify the temperature distribution. The spatial temperature distribution of the encapsulant and blue LED die region was easily simulated and predicted. The obtained results are not only helpful in detecting the temperature behavior inside the packaging volume but also meaningful for designing the package config

The main body of this thesis is devoted to the investigation of the quasiparticle spectra of neutral gold clusters by using the GW method. We focus on the study of small clusters AuN (N=1-8) (including the Au atom), as well as two larger quasi two-dimensional clusters, the tetrahedral Au20 cluster and the cagelike Au32 cluster. The Quantum Espresso density-functional package is employed to perform electronic structure calculations. In particular, the GWL module of Quantum Espresso is used for the GW parts of the calculations. Our implementation of the GW method has incorporated recently introd

Abstract:
In recent years, the physics community has experienced a revival of interest in spin effects in solid state systems. On one hand, solid state systems, particularly semicon- ductors and semiconductor nanosystems, allow one to perform benchtop studies of quantum and relativistic phenomena. On the other hand, interest is supported by the prospects of realizing spin-based electronics where the electron or nuclear spins can play a role of quantum or classical information carriers. This book aims at rather detailed presentation of multifaceted physics of interacting electron and nuclear spins in sem

Abstract:
Detonation propulsion, both rocket-type and air-breathing, is currently a topical direction of research worldwide. Attention is mainly paid to various modes of operation of such engines, their stability, and reliability. As for the issues related to the initiation of the detonation process in such engines, they are usually not considered in detail. However, the initial stage of development of the operation process can be accompanied by a signi¦cant increase in the pressure acting on engine structural elements [1].
