Accurate prediction of the final shape using numerical modeling has been a top priority in the field of sheet and bulk forming. Better shape prediction is the result of a better estimation of the physical stress and strain state. For experimental and numerical investigations of such estimations, simple benchmark processes are used. In this paper a benchmark process involving forging (flattening...

In der Vergangenheit wurden medizintechnische Projekte typischerweise klassisch gemäß V-Modell durchgeführt. Wir untersuchen, wie die klassische Vorgehensweise mit agilen Elementen kombiniert werden kann, so dass man die Flexibilität des agilen Ansatzes nutzen kann und gleichzeitig die strengen Anforderungen an die Abnahme von Medizinprodukten erfüllt werden können. Das vorgestellte Konzept zum...

NeP1 binds to the F1 silencer element of the chicken lysozyme gene and, in the presence of TR, v-ERBA or RAR, synergistically represses transcriptional activity. This repression involves a silencing mechanism acting independently of the relative promoter position. Here we show that NeP1 alone can induce a significant directed bend on DNA. The chicken homologue of human NeP1, CTCF, shows identic...

Piezotronics is a new field integrating piezoelectric effect into nanoelectronics, which has attracted much attention for the fundamental research and potential applications. In this paper, the piezotronic effect of zinc oxide (ZnO) nanowires, including the response of the electrical transport and photoconducting behaviors on the nanowire bending, has been investigated by in situ transmission e...

Working on the design of products obtained by V-bending, engineer uses nominal thickness material. In this case, problem is to evaluate accuracy linear dimensions resulting due deviations in material and manufacturing technology steel sheets. Article presents analysis dimension for V-bending metal cold-rolled hot-rolled sheets with 1.0…8.0 mm width from 1000…1500mm. Proposed method based calcul...

Die behandeling en versorging van pasiënte wat aan akute miokardinfarksie ly , het die afgelope dekade opvallend verbeter. Daar het nuwe opvattings i.v .m . die behandeling van kardiogeniese skok ontstaan. Die onafgebroke waarneming van harthemodinamika deur koronêre sorgverpleegsters het die grootskaalse vooruitgang t.o .v . geneeshere se huidige “ koronêre sorg” moontlik gem aak. Die gebruik ...

Die Verbesserung von Softwareund Systementwicklungsprozessen ist eine wichtige Aufgabe zum Erhalt und Ausbau der Wettbewerbsfähigkeit von Unternehmen. Allerdings ist die praktische Umsetzung entsprechender Verbesserungsmaßnahmen in der Praxis mit großen Schwierigkeiten und Risiken verbunden. Ein hoher Prozentsatz entsprechender Programme scheitert. Entscheidende Erfolgsfaktoren für Prozessverbe...

Vibrational energy relaxation of HOD in deuterated water is investigated performing classical nonequilibrium molecular dynamics simulations. A flexible SPC/E model is employed to describe the intermolecular interactions and the intramolecular potential of the D(2)O solvent. A more accurate intramolecular potential is used for HOD. Our results for the OH stretch, OD stretch, and HOD bend vibrati...

Kormylo and Mendel proposed a maximum-likelihood deconvolution (MLD) algorithm for estimating a desired sparse spike sequence p.(k), modelled as a Bernoulli-Gaussian (B-G) signal, which was distorted by a linear time-invariant system v(k). Then Chi, Mendel and Hampson proposed another MLD algorithm which is a computationally fast MLD algorithm and has been successfully used to process real seis...
