Highly Complex Green Parts in Excellent Quality

Nies Norbert,Peters Detlef 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1

SMS Meer GmbH, formerly Mannesmann and today part of the SMS Group, has been building powder presses since the early 1950s. The patents developed here in this field have long since documented the pioneering work carried out for the PM industry. The paper focuses on the challenge of reconciling the contradictory demands in the production of highly complex and crack-free PM parts. The process employed with the patented Controlled Punch Adapter (CPA) [1] counters possible cracking reliably and directly at the source. In this way is it possible to develop new and highly complex parts to series production maturity in a minimum of time even without simulation of the press cycle [2]. The quality data achieved in the production series, almost 100% crack and micro crack-free green parts with optimum density distribution over all press levels is unrivalled and thus gives the user a clear lead over the competition.

Modelling of marine radionuclide dispersion in IAEA MODARIA program: Lessons learnt from the Baltic Sea and Fukushima scenarios

Models were of different nature, from box to full three-dimensional models, and included water/sediment interactions. Agreement between models was very good in the Baltic. In the case of Fukushima, results from models could be considered to be in acceptable agreement only after a model harmonization process consisting of using exactly the same forcing (water circulation and parameters) in all models. It was found that the dynamics of the considered system (magnitude and variability of currents) was essential in obtaining a good agreement between models. The difficulties in developing operative models for decision-making support in these dynamic environments were highlighted. Three stages which should be considered after an emergency, each of them requiring specific modelling approaches, have been defined. They are the emergency, the post-emergency and the long-term phases.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Models applied to simulate <SUP>137</SUP>Cs marine dispersion after nuclear accidents. </LI> <LI> Not good agreement initially found in highly dynamic environments. </LI> <LI> Difficulties in developing models for decision making after emergencies highlighted. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

은희경의 「내가 살았던 집」에 나타나는 영화적 기법

김예니(Kim Ye-Nie) 돈암어문학회 2005 돈암어문학 Vol.- No.18

The strategy of the narrative in the novel of Eun Hi-Kyoung is verified. First, in her text whose character has “the cynical smile” and “the feigned wickedness”, which has the peculiarity that a “focalizer” and “voice” in the text is divided and overlaped. When a focalizer and voice is certainly divided, a focalizer secures the distance with the objectivity and just get a view of the world and the object as well as a character in the text with a view of “the cynical smile” and “the feigned wickedness”. But in the story about the past which is located in the interval of the present time, a focalizer and voice is unjustly divided, or overlaped almost. And throughout this story about the past, A event of the precent which looks meaningless acquires the meaning. At this time, we can realize that the writer is hiding away a restrained desire and thought behind the “the cynical smile”.<br/> Second, the Hard-cut of Montage which appears in the 「The House that I had been」 shows the transformed space made in the memory which looks the object. The arrangement that the past and the present, or difficult stories, or the object and the space stand in a line gives a reader the construable space. At the same time, the meaningless event that happens now has the meaning throughout the memory about the past and a reader can see and feel the space closer than others. Those peculiarities are the modern novel's and film-art's. Eun Hi-Kyoung makes the effect throughout the strategy of the narrative which evokes “the cynical smile” and "the feigned wickedness" that it is made in that a focalizer and voice is divided and overlaped, or situations and shots stand in a line.

Model-Based Design Methodology for Digital Up and Down Conversion of Software Defined Radio

Nie Yang,Ge Hua,Jing Li-li,Zhao Peng-yu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.4

This paper proposes an efficient implementation of digital up and down conversion for Software Defined Radio (SDR) using Model-Based Design (MBD). In particular, a novel flow for designing digital up and down conversion is detailed. Using MBD, a system model is at the center of the development process, from requirement development, through design, implementation, and testing. Using MBD, code can be automatically generated for system and create test benches for system verification, which is saving time and avoiding the introduction of manually coded errors. Design example shows that the proposed method can greatly reduce the complexity of digital up and down conversion while providing the efficient and reliability of design flow.

훈민정음 ‘후설위주’와 ‘청탁ㆍ합벽’, 사성 의미에 관한 고찰

NIE BAOMEI 한국언어문학회 2016 한국언어문학 Vol.97 No.-

In this study, we analyze the deep meaning of ‘喉舌爲主', '淸濁' and '闔闢' term, the four tones in Hunminjeongeum Haireibon from I-Ching and phonetical view. As we all known that throat(喉) and tone(舌) are the most important articulator, not only because they are applicable to water(水) and fire(火) of the five elements, but only because they are also important than tooth and lip as phonetics articulator. In Hunminjeongeum the meaning of Chinese character '喉' includes the epiglottis(會厭) deeply. '淸濁' and '闔闢' can be used as I-Ching and phonetical term. Considering the effectiveness and briefness of depiction in Hunminjeongeum, the '闔闢' of hangeul consonants was skipped by Haireibon compiler. To the four tones of Hangeul, phonetics nature and I-Ching nature are two sides of the same coin. The four tones was assigned at the four seasons. It referred to harmony principle of spirit(氣) in Taijitushuo(太極圖說). The examples of four tones, ‘弓, 石, 刀' symbolize the military service examination,(武 科) '筆’ symbolize Civil Service Examination(文科). Hunminjeongeum was made for subjects whoever want take the state examination.

Snap-through buckling of single-layer squarely-reticulated shallow spherical shells continuously supported on springs

Nie, G.H. Techno-Press 2000 Structural Engineering and Mechanics, An Int'l Jou Vol.10 No.2

An asymptotic solution for snap-through buckling of single-layer squarely-reticulated shallow spherical shells continuously supported on springs is developed in this paper. Based on the fundamental governing equations and boundary conditions, a nondimensional analytical expression associated with the external load, stiffness of spring and central transverse displacement (deflection) is derived with the aid of asymptotic iteration method. The effects of stiffness of spring and characteristic geometrical parameter on buckling of the structures are given by the analyses of numerical examples. In a special case, for reticulated circular plates, the influence of stiffness of spring on the characteristic relation between load and deflection is also demonstrated.

Model-Based Design Methodology for Sampling Rate Converter

Nie Yang,Ge Hua,Jing Li-li 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.5

The design of high-speed sampling rate converter in multi-rate system is a very complicated problem. The traditional development flow is not simply low efficiency, and but also is difficult to implementation. This paper presents a development flow by model-based design to simplify the design process, to improve work efficiency. Sampling rate converter is designed by a hybrid scheme using polyphase filter and Farrow filter structure. Through the development flow of model-based design, circuit modeling is very easy to do, and the RTL code and test code are automatically generated. The simulation results show that this method can greatly reduce the system consumption and promote the performance of the system.
