Design for Low-Cost Country Sourcing: Motivation, Basic Principles and Design Guidelines
Organised by: Cranfield UniversityNot every product can be successfully sourced in low-cost countries. Disadvantageous cost structures or
extremely complex workpiece designs are the most frequent reasons for failures. A design that has been
tailored to low-cost country sourcing offers the possibility of increasing potentials while reducing risks and
costs at the same time. The wbk Institute of Production Science at the Universität Karlsruhe (TH) developed
a new approach which ensures that the product design meets the requirements of the supplier. This paper
identifies the factors influencing the design, deduces basic principles and illustrates guidelines for an
adapted product design.Mori Seiki – The Machine Tool Compan

Dust-Gas Interaction in SNR 1987A
Multiwavelength observations of SNR 1987A show that its morphology is rapidly
changing at X-ray, radio, and optical wavelengths as the blast wave from the
explosion expands into the circumstellar equatorial ring. Infrared emission
arises from the interaction of dust grains with the hot X-ray emitting gas. We
show that the IR emission provides important complementary information on the
interaction of the SN blast wave with the circumstellar equatorial ring that
cannot be obtained at any other wavelength.Comment: 8 pages, 4 figures; review talk to appear in the AIP Proceedings of

Sequential Flavour Symmetry Breaking
The gauge sector of the Standard Model (SM) exhibits a flavour symmetry which
allows for independent unitary transformations of the fermion multiplets. In
the SM the flavour symmetry is broken by the Yukawa couplings to the Higgs
boson, and the resulting fermion masses and mixing angles show a pronounced
hierarchy. In this work we connect the observed hierarchy to a sequence of
intermediate effective theories, where the flavour symmetries are broken in a
step-wise fashion by vacuum expectation values of suitably constructed spurion
fields. We identify the possible scenarios in the quark sector and discuss some
implications of this approach.Comment: 22 pages latex, no figure
Pulsar "Drifting"-Subpulse Polarization: No Evidence for Systematic Polarization-Angle Rotations
Polarization-angle density displays are given for pulsars B0809+74 and
B2303+30, which exhibit no evidence of the systematic polarization-angle
rotation within individual subpulses previously reported for these two stars.
The ``drifting'' subpulses of both pulsars exhibit strikingly linear and
circular polarization which appears to reflect the characteristics of two
nearly orthogonally polarized emission ``modes''--along which the severe
average-profile depolarization that is characteristic of their admixture at
comparable overall intensities.Comment: Accepted for publication in Astronomy & Astrophysic
