Abstract: A system and method upgrade software applications offline using a virtual machine. Software applications used by actual customer machines may rely upon customer specific data and protocols. An upgraded version of a software application may become available. The upgrade may be loaded onto a virtual machine. Customer specific data or protocols associated with a previous version of the application may be copied to the virtual machine. The upgraded version may be modified on the virtual machine using the data associated with the previous version. The upgrade process using the virtual machine may detect and eliminate problems with the upgrade associated with the customer machine and/or settings. Once modified, the upgraded version may be transferred from the virtual machine to the customer machine. The upgrade process may be performed primarily on the virtual machine. Therefore, the downtime of the customer machine required to complete the upgrade process may be substantially reduced.

Abstract: The present embodiments specify a method and an associated X-ray facility for estimating a radiation dose of an X-ray that is generated by an X-ray source and penetrates an object under examination. First dose values of the X-ray are determined by measurement in an automatic exposure control chamber. A second dose value is determined by estimating the radiation dose that is emitted by an X-ray source in a dead time of the automatic exposure control chamber. The estimated radiation dose is determined by the first dose value and the second dose value last determined being added. The second dose value represents a correction value for a non-measurable dose during the dead time of the automatic exposure control chamber that is taken into account when determining the estimated radiation dose.

Abstract: A tractable abduction procedure for a lightweight description logic EL is introduced extending recent research on automata-based axiom pinpointing by assuming information from a predefined abducible part of the domain model. The approach is motivated by the need for efficient diagnostic reasoning for large-scale industrial systems where observations are partially incomplete and often sparse. A weighted automaton can be constructed that commonly encodes a definite and abducible part of the domain model. Advantageously, the approach provides a compact representation of all possible hypotheses explaining an observation, and is in fact computable in PTIME. The procedure can be used for controlling, adjusting or diagnosing all kinds of technical systems, in particular in the area of industry and automation.

Abstract: In a method to generate magnetic resonance (MR) images of an examination subject, MR signals are detected simultaneously with multiple coils, each coil having its own coil characteristic. In the detection of the MR signals, raw data space is incompletely filled with MR signals; with raw data space being undersampled in a central raw data region with a coherent acquisition pattern that is composed of a spatially repeating set of raw data points; and raw data space outside of the central raw data region is sampled with an incoherent acquisition pattern. The MR image is reconstructed from the detected MR signals, step-by-step in an iterative reconstruction procedure using a reconstruction matrix A, starting from an initial estimate; wherein the reconstruction matrix has continuing information about the coil characteristics with which the MR signals were detected.
