Simulation of waviness in neutron guides

As the trend of neutron guide designs points towards longer and more complex guides, imperfections such as waviness becomes increasingly important. Simulations of guide waviness has so far been limited by a lack of reasonable waviness models. We here present a stochastic description of waviness and its implementation in the McStas simulation package. The effect of this new implementation is compared to the guide simulations without waviness and the simple, yet unphysical, waviness model implemented in McStas 1.12c and 2.0

FabIO:easy access to two-dimensional X-ray detector images in Python

FabIO is a Python module written for easy and transparent reading of raw two-dimensional data from various X-ray detectors. The module provides a function for reading any image and returning a fabioimage object which contains both metadata (header information) and the raw data. All fabioimage objects offer additional methods to extract information about the image and to open other detector images from the same data series.</jats:p

When global process fails: A grounded theory study of a case from agile engagement to compulsive outsourcing

Abstract. In a Scandinavian company developing a healthcare information system (IS) at three Scandinavian sites they succeeded in taking agile processes into use across the three sites. After a fourth development site in India was added the use of agile development processes gradually came to an end and plan-driven processes took over. In this paper we report from a month-long study where our analysis of the case shows that the cause for giving up agile was three-fold: (1) The cultural distance between India and Scandinavia was too great. (2) There were telling differences in competence and (3) the presence of knowledge asymmetry. From this analysis we develop a grounded theory explaining the necessary preconditions for succeeding with a global process for agile IS development
