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
On Higgs-exchange DIS, physical evolution kernels and fourth-order splitting functions at large x
We present the coefficient functions for deep-inelastic scattering (DIS) via
the exchange of a scalar phi directly coupling only to gluons, such as the
Higgs boson in the limit of a very heavy top quark and n_f effectively massless
light flavours, to the third order in perturbative QCD. The two-loop results
are employed to construct the next-to-next-to-leading order physical evolution
kernels for the system (F_2 F_phi) of flavour-singlet structure functions. The
practical relevance of these kernels as an alternative to MSbar factorization
is bedevilled by artificial double logarithms at small values of the scaling
variable x, where the large top-mass limit ceases to be appropriate. However,
they show an only single-logarithmic enhancement at large x. Conjecturing that
this feature persists to the next order also in the present singlet case, the
three-loop coefficient functions facilitate exact predictions (backed up by
their particular colour structure) of the double-logarithmic contributions to
the fourth-order singlet splitting functions, i.e., of the terms (1-x)^a
ln^k(1-x) with k = 4, 5, 6 and k = 3, 4, 5, respectively, for the off-diagonal
and diagonal quantities to all powers a in 1-x.Comment: 75 pages, LaTeX, 13 figures (.eps). FORM and Fortran files of main
