For an efficient design process of complex mechatronic systems a continuous and verification-orientated model-based methodology with Model-in-the-Loop (MiL), Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) simulation is suitable. Using such an approach the real-time capable nonlinear multi-body system model of the entire vehicle with the electric power train and the identification of the physical parameters are described. A continuous appliance of the introduced model is a contribution for the frontloading and guarantees a time and cost efficient mechatronic design approach.

Aus zahlreichen Normen kommt die Forderung nach einem Eignungsnachweis für Prüfprozesse. Der Fachartikel stellt Vorgehen und Methoden vor, um den Aufwand für den Nachweis einer Prüfprozesseignung zu verringern. Zum einen wird der Umgang mit einer Vielzahl an Prüfprozessen mittels eines risikobasierten Ansatzes vorgestellt und zum anderen ein strukturiertes Verfahren zur Modellbildung bei komplexeren Prüfprozessen skizziert. Beide Verfahren sind Bestandteil der VDI/VDE-Richtlinienreihe 2600.   Many standards and guidelines demand a proof of capability for inspection processes. In this article procedures and methods for reducing the costs for the proof of capability are presented. At first, the handling of many inspection processes using a risk-based approach is described. Second, a structured, model-based approach for the proof of capability of complex inspection processes is outlined. Both topics are part of the VDI/VDE 2600 guideline series.

The Cost

Recently, a branch of multilevel converters is emerged, in which their ‘reduced structure’ topologies use lower number of devices compared to the available topologies. To get a cost efficient converter, lower number of components as well as high quality waveforms, multilevel converters with a ‘reduced structure’ (MCRS) are suitable for high/medium power systems. Also, utilizing the fast microprocessors available today, applications of predictive control in power converters are of very powerful and attractive alternatives to classical controllers. This paper proposes a finite control set model-based predictive control (FCS-MPC) for load current regulation and capacitor voltage balancing for a typical MCRS. A case study considered, three-phase seven level packed U-cell (PUC), which is among reduced structure multilevel converters. A discrete model of the system is derived, and a predictive model-based control is developed according to this model in order to predict the future behavior of the system for all possible switching states; then, the switching state that optimized the cost function is selected. The feasibility of the proposed FCS-MPC strategy for a seven level PUC is evaluated based on simulations with MATLAB/ SIMULINK. Moreover, experimental validation of the proposed control system on a 5 kVA PUC is examined through DSP implementation<strong>.</strong>

Abstract Bayesian decision theory provides a simple formal elucidation of some of the ways that representation and representational abstraction are involved with, and exploit, both prediction and its rather distant cousin, predictive coding. Both model-free and model-based methods are involved.

The extracellular matrix (ECM) plays a critical role in directing cell behaviour and morphogenesis by regulating gene expression and nuclear organization. Using non-malignant (S1) human mammary epithelial cells (HMECs), it was previously shown that ECM-induced morphogenesis is accompanied by the redistribution of nuclear mitotic apparatus (NuMA) protein from a diffuse pattern in proliferating cells, to a multi-focal pattern as HMECs growth arrested and completed morphogenesis . A process taking 10 to 14 days.To further investigate the link between NuMA distribution and the growth stage of HMECs, we have investigated the distribution of NuMA in non-malignant S1 cells and their malignant, T4, counter-part using a novel model-based image analysis technique. This technique, based on a multi-scale Gaussian blur analysis (Figure 1), quantifies the size of punctate features in an image. Cells were cultured in the presence and absence of a reconstituted basement membrane (rBM) and imaged in 3D using confocal microscopy, for fluorescently labeled monoclonal antibodies to NuMA (fαNuMA) and fluorescently labeled total DNA.
