The correlation between the intensities of partially or fully developed far-field speckle patterns of two different wavelengths is investigated, assuming Gaussian field amplitudes. The degree of spectral speckle correlation depends mainly on the standard deviation of the surface height distribution, the wavelength difference, the angle of incidence, and the number of independent scattering cells in the illuminated surface spot.
It provides a simple way of performing noncontact surface-roughness measurements with a variable measuring range. The theory, which has so far been restricted to fully developed speckle patterns with circular field statistics, is extended to partially developed speckles.
Assumptions about the circularity or noncircularity of the speckle patterns are not necessary. An experiment has been carried out to support the theoretical results.
Powder-Injection-Moulding PIM offers a high potential for the fabrication of micro-mechanical parts manu-factured in wear-resistant materials like metal or ceramics. To ensure an economic micro-PIM production in large lot sizes and high quality, automation of the process is a necessity.
Within the field of automation research it is of utmost importance to set up correlations between producible sizes, microstructure geome-tries, the demoulding capability and the separation of microstructures from sprues.
The paper presents an approach of a closed automated process chain with the focus on the demoulding, separation and handling of fragile micro parts.
With the development of the WEDG wire-electrodischarge-grinding it became possible to produce very small electrodes or products like e. A new field for the WEDG is the production of milling tools for micro-cutting. The ramp-up of a new production system has become a decisive factor influencing profif.
The reason is an incessantly growing product range with constantly decreasing life cycles. Characterisfic for ramp-up processes are insfable production processes, that Iead to a! The approach of Quality Simulation presented in this paper allows simulafing the insfable stafe of a production sysfem during ramp-up.
Thus, the produclion planner is supporled during both ramp-up planning and 1he actual ramp-up period. Using Quality Simulation the planner can idenlify deviations from the target ramp-up curve at an early stage. High-Perfimnance-Cutting jor the broaching process involves the combination of dry machining and high cutting velocities.
This can only be obtained through the progress in tool development. Therefore, the required toolmodifications have to be designed and tested so as to determine the in principle producibility, the tool wear, the applicable cutting forces and the workpiece quality that is achievable.

Today several suppliers optimise their own parts of the system in terms of cost, cycle time and reliability. In most cases, there is no transparency about the process chain, the capabilities and necessities of handfing and automation functions on all supplier levels.
Therefore, it is not possible to find the overall optimum and hereby to reduce the total investment volume.
Nowadays, production technology faces the challenge to manufacture small components within tight tolerances, yet,which still remain economical in large lots.For this purpose, two new and one adapted congestion control approach – all based on the Resource Pooling principle – will be introduced and examined in similar as well as dissimilar path setups, in order to show how to fairly deploy CMT transport in the Internet.
The second day trip will bring us to an ecological business that also initiates regional cultural and educational activities. People will get hands on experience in the garden and explore, collect and process local wild herbs as example of nutritious and healthy local food.
Implementing that plan will probably take more effort, but it is. Ilya V. Gerasimov «Russians into Peasants?» The Politics of Self-Organization and Paradoxes of the Public Modernization Campaign in the Countryside in Late Imperial Russia1 1.
The Doing Business database now covers seven sets of indicators covering countries for two years. Annual updates will follow. Topics include registering a business, hiring and firing labor, getting credit, enforcing a contract, transferring property, investor protection, and bankruptcy.
frictions resulting from economic restructuring and the decline in the appeal of some locations as a base for industry, there is however no question of the tools of planning being abandoned wholesale; what is needed is for them to be adapted to meet changed socio-economic circumstances and new political and/or administrative requirements.
