There are a wide range of physical defects which occur during metal forming processes. These defects, which may occur on the surface or be internal, are undesirable not only because of the surface appearance, but because they may adversely affect the strength, formability and other manufacturing characteristics of the material. Some physical defects in metal forming processes such as rolling an...

Das Tierseuchennachrichtensystem (TSN) ist das einheitliche Computergestützte nationale Berichtssystem für Tierseuchen und Tierkrankheiten, welches seit 1995 in allen Veterinärbehörden Deutschlands genutzt wird. Seit der Einführung der ersten WindowsVersion von TSN im Dezember 2000 wurde das System zu einem Krisenmanagementsystem weiterentwickelt. Neben der Integration von Internet-Technologien...

The shape of a probability distribution is often summarized by the distribution’s skewness and kurtosis. Starting from a symmetric “parent” density f on the real line, we can modify its shape (i.e. introduce skewness and in-/decrease kurtosis) if f is appropriately weighted. In particular, every density w on the interval (0, 1) is a specific weighting function. Within this work, we follow up a ...

A comparison was made between Dartnall’s standard shape for visual pigmentsand the spectral sensitivities of the short-, middle-, and long-wavelength sensitive cone receptormechanisms of man. Data from blue monocone monochromats, protanopes, and deuteranopeswere chosen as reliable estimates of each of the three classes of cone sensitivities. The short-wavelength sensitive mechan...

The probability of a high roll is larger for the biased dice than for the fair dice. Suppose that you draw a die at random from the box and roll it twice, observing a four on the first roll and a six on the second roll. What is the probability that the die is biased? A Bayesian analysis combines ones prior beliefs about the probability of a hypothesis with the likelihood. The likelihood is the ...

Recent evolutions on forging process induce more complex shape on forging die. These evolutions, combined with High Speed Machining (HSM) process of forging die lead to important increase in time for machining preparation. In this context, an original approach for generating machining process based on machining knowledge is proposed in this paper. The core of this approach is to decompose a CAD...

We propose a new method for carrying out field-theoretic simulations of polymer systems under conditions of prescribed external stress, allowing for shape changes in the simulation box. A compact expression for the deviatoric stress tensor is derived in terms of the chain propagator, and it is used to monitor changes in the box shape according to a simple relaxation scheme. The method allows fu...

The feasibility of fabricating polypropylene (PP) nanofibers has been explored by using different additives, such as sodium oleate (SO), poly(ethylene glycol) (PEG) and poly(dimethyl siloxane) (PDMS), during melt electrospinning. PP of high melt flow index (1000) was used with PEG and PDMS for the reduction of the melt viscosity; and it was used with SO for improving the electrical conductivity...
