THE LIVEWEIGHT GAIN OF CATTLE AT PASTURE IN SOUTH SULAWESI SUPPLEMENTED WITH LOCALLY AVAILABLE BY-PODUCTS

Till, A.R.,Hunt, M.R.,Panggabean, T.,Bulo, D.,Blair, G.J. Asian Australasian Association of Animal Productio 1991 Animal Bioscience Vol.4 No.1

Weaner heifers were set stocked at 4/ha on a grass-legume pasture in South Sulawesi, Indonesia, and either unsupplemented (Control) or for 338 days given daily supplements of one of, rice bran (RB) supplied at 1 kg/animal/d, molasses/urea (MU) or 0.5 RB + 0.5 MU (MURB) the amounts of which were adjusted to give similar energy intakes. There were 20 animals in each treatment. A drought resulted in low pasture availability for about half the supplementation period. The LWG per animal in the MURB treatment was 85 kg above that of the control and this was significantly greater (p < 0.01) than those for MU (62.0 kg) or RB (56.2 kg) although the economics favoured the gains from RB which returned over three times the cost of the supplement. Costs could be reduced by supplementing only at times of maximum undernutrition, but such a strategy is of doubtful value in this situation as there was no compensatory LWG and a similar rate of economic return was maintained throughout the period. The results suggest that additional benefits from the supplementation may be improved reproductive performance and more efficient use of pasture.

이 논문에서는 우선 제2차 세계대전 이후 20세기 후반 유럽에서 수사학이 재발견되는 역사를 개관하고 2장 이후 본론에서는 수사학에 대해 긍 정적인 입장을 표명한 철학자들 가운데 지금까지 덜 알려진 철학자 그라씨(1902-1991)의 저작, 특히 『이미지의 힘. 합리적 언어의 무력함』(1970)을 중심으로 그의 수사학 구상을 비판적으로 고찰한다. 20세기 후반 유럽대륙에서 수사학의 재발견은 논리학과 법철학 분야에서 페렐만과 툴민에 의해, 문학학자 쿠르티우스와 기호학자 롤랑 바르트 에 의해, 비유와 표현무늬 분야에서 뒤브아와 플레트에 의해, 그리고 튀빙엔 대학의 발터 옌스가 창건한 일반수사학과에 의해 이루어진다. 수사 학에 대해 여전히 대체로 거리를 두고 있던 철학 분야에서는 로티를 중심으로 한 언어학적 전환, 데리다와 폴 드 만의 포스트모던과 해체주의의 흐름와 함께 달라진다. 수사학에 대해 긍정적인 입장을 표명한 철학자로는 가다머와 블루멘베르크를 들 수 있는데 니체『( 수사학 강의』)와 하이데거『( 존재와 시간』)는 그들에게 적지 않은 영향을 준 선배 철학자들이다. 가다머와 함께 하이데거의 제자인 그라씨는 가다마처럼 데카르트 이후 근대 철학에 비판적인입장으로 『이미지의 힘. 합리적 언어의 무력함』에서 철학의 수사학에 대한 비방의 역사를 재구성하고 이미지, 수사학, 비유를 복권시키면서 수사학을 철학의 중심에 세워놓으려 한다. 그라씨의 저작들은 20세기 후반 철학자의 수사학에 대한 새로운 관심을 보여주는 중요한 증거자료임에는 틀림없다. 그는 독일에서는 덜 알려져 있지만 미 국에서는 특히 1980년대에 그의 저작들이 번역되고 ‘철학과 수사학’ 학술지에 일련의 논문들도 게재되면서 수용되었고 영국에서도 수사학 개설서에 소개되어 있다. 그라씨** 가 독일에서 거의 잊혀진 이유는 그라씨 텍스트의 취약성에도 한 원인이 있다. 수사적인 것과 비유적인 것, 이미 지적인 것을 동일시하는그의 수사학 개념은 프랑스의 문학이론가 쥬네트가 말한 줄어든 형태의 수사학과 다르지 않다. 그라씨는 발견/착상과 관 련해서도 말터 체계에서 나오는 논거의 발견이 아니라 타고난 재능, 창의성, 예술가적인 발견의 측면을 강조한다. 생활세계와 공통 말터에 근거한 말터 개념이 그에게는 결여되어 있다.

Assessment of statistical sampling methods and approximation models applied to aeroacoustic and vibroacoustic problems

Biedermann, Till M.,Reich, Marius,Kameier, Frank,Adam, Mario,Paschereit, C.O. Techno-Press 2019 Advances in aircraft and spacecraft science Vol.6 No.6

The effect of multiple process parameters on a set of continuous response variables is, especially in experimental designs, difficult and intricate to determine. Due to the complexity in aeroacoustic and vibroacoustic studies, the often-performed simple one-factor-at-a-time method turns out to be the least effective approach. In contrast, the statistical Design of Experiments is a technique used with the objective to maximize the obtained information while keeping the experimental effort at a minimum. The presented work aims at giving insights on Design of Experiments applied to aeroacoustic and vibroacoustic problems while comparing different experimental designs and approximation models. For this purpose, an experimental rig of a ducted low-pressure fan is developed that allows gathering data of both, aerodynamic and aeroacoustic nature while analysing three independent process parameters. The experimental designs used to sample the design space are a Central Composite design and a Box-Behnken design, both used to model a response surface regression, and Latin Hypercube sampling to model an Artificial Neural network. The results indicate that Latin Hypercube sampling extracts information that is more diverse and, in combination with an Artificial Neural network, outperforms the quadratic response surface regressions. It is shown that the Latin Hypercube sampling, initially developed for computer-aided experiments, can also be used as an experimental design. To further increase the benefit of the presented approach, spectral information of every experimental test point is extracted and Artificial Neural networks are chosen for modelling the spectral information since they show to be the most universal approximators.

Crash Simulation of Roll Formed Parts by Damage Modelling Taking Into Account Preforming Effects

Edwin T. Till,Benjamin Hackl,Hermann Schauer 한국소성가공학회 2011 기타자료 Vol.2011 No.8

Complex phase steels of strength levels up to 1200 ㎫ are suitable to roll forming. These may be applied in automotive structures for enhancing the crashworthiness, e. g. as stiffeners in doors. Even though the strain hardening of the material is low there is considerable bending formability. However ductility decreases with the strength level. Higher strength requires more focus to the structural integrity of the part during the process planning stage and with respect to the crash behavior. Nowadays numerical simulation is used as a process design tool for roll-forming in a production environment. The assessment of the stability of a roll forming process is quite challenging for AHSS grades. There are two objectives of the present work. First to provide a reliable assessment tool to the roll forming analyst for failure prediction. Second to establish simulation procedures in order to predict the part’s behavior in crash applications taking into account damage and failure. Today adequate ductile fracture models are available which can be used in forming and crash applications. These continuum models are based on failure strain curves or surfaces which depend on the stress triaxiality (e. g. Crach or GISSMO) and may additionally include the Lode angle (extended Mohr Coulomb or extended GISSMO model). A challenging task is to obtain the respective failure strain curves. In the paper the procedure is described in detail how these failure strain curves are obtained using small scale tests within voestalpine Stahl, notch tensile?, bulge and shear tests. It is shown that capturing the surface strains is not sufficient for obtaining reliable material failure parameters. The simulation tool for roll-forming at the site of voestalpine Krems is Copra® FEA RF, which is a 3D continuum finite element solver based on MSC.Marc. The simulation environment for crash applications is LS-DYNA. Shell elements are used for this type of analyses. A major task is to provide results of the roll forming simulation as initial conditions for the crash model, taking over the shell thickness, the variation of the plastic strain and the damage parameter over the profile. This is realized by a python [13] interface program. Profiles are manufactured by the roll forming facility in Krems with a complexphase steel grade of 980 ㎫ strength. The final samples are manufactured using the profiled parts with cover plates fixed to them by spotwelds. Axial crash experiments are carried out using the inhouse horizontal crash test facility. It is observed that the component shows good folding behavior with some minor failure sites at edges where there is extensive forming during roll-forming. Simulation runs are made with LS-DYNA using the GISSMO damage model. The results match reasonably well with the experimental results. The simulation tool seems to be useful in order to assess not only the integrity of the roll-forming process but also to adequately predict the crash behavior of roll-formed components. Some suggestions are made in order to improve the simulation of the evolution of damage after initiation in the future.
