Although white-light interferometers have become well-established tools for measuring smooth, rough, and micro-structured surfaces, there are some limitations in certain applications, e.g., if tilted surface areas or small radii of curvature are to be measured. Since the correction of chromatic aberrations is not perfect over the total field of view or the total pupil plane, dispersion differences occur for different ray paths of the microscopic imaging system. The influence of these effects is discussed on the basis of the most commonly used Mirau interferometer, and the resulting systematic measuring errors are explained. © 2010 Optical Society of America.

The significant growth in the academic literature on sustainable supply chain management (SSCM) can best be seen by the fact that three review papers have been published since 2007. In line with this, the question emerged - what distinguishes sustainable supply chain management from 'conventional' supply chain management? Here, the strategy of supply chain management for sustainable products proposed by Seuring and Müller (2008a) will be discussed. Against this background, this paper aims to develop a theory for sustainable supply chain management. While other contributions are taken into account, this will be primarily based on our own research spanning about 10 years and using multiple research methods. The empirical methods employed include: (1) case studies, (2) action research, (3) Delphi study, (4) survey research, and (5) literature reviews based on content analysis. The paper will provide insights into what was learned from the different research projects and how this has helped to gain a better and wider understanding of the field. This is discussed further by presenting hypotheses which should help to further advance the theory of supply chain management for sustainable products. © 2010 John Wiley & Sons, Ltd and ERP Environment.

More than 300 papers have been published in the last 15 years on the topic of green or sustainable (forward) supply chains. Looking at the research methodologies employed, only 36 papers apply quantitative models. This is in contrast to, for example, the neighboring field of reverse or closed-loop supply chains where several reviews on respective quantitative models have already been provided. The paper summarizes research on quantitative models for forward supply chains and thereby contributes to the further substantiation of the field. While different kinds of models are applied, it is evident that the social side of sustainability is not taken into account. On the environmental side, life-cycle assessment based approaches and impact criteria clearly dominate. On the modeling side there are three dominant approaches: equilibrium models, multi-criteria decision making and analytical hierarchy process. There has been only limited empirical research so far. The paper ends with suggestions for future research. © 2012 Elsevier B.V.

Time-periodic solutions to the linearized Navier-Stokes system in the n-dimensional whole-space are investigated. For time-periodic data in L q-spaces, maximal regularity and corresponding a priori estimates for the associated time-periodic solutions are established. More specifically, a Banach space of time-periodic vector fields is identified with the property that the linearized Navier-Stokes operator maps this space homeomorphically onto the Lq-space of time-periodic data. © 2014 Springer Basel.

A study was conducted to demonstrate coherent control of ultracold photoassociation. The case of resonantly enhanced two-photon dissociation was examined to introduce the theoretical framework for the investigations. The methodology developed for the two-photon dissociation problem was applied to resonantly enhanced photoassociation. The initial state in photoassociation involved the scattering state and the goal was to transfer the population to the final bound state. The pulse intensities used were sufficiently small to avoid unwanted photoionization, photodissociation, and other strong field parasitic processes. It was demonstrated that working with pulses required that the atoms be sufficiently close to one another during the laser pulse, allowing them to be recombined. The initial wave packet of continuum states considered in the study needed to be synchronized in time and in duration with the recombining pulses.
