Traditionally, Electronic Medical Records (EMR) have been designed to mimic paper records. Organizing and presenting medical information along the lines that evolved for non-digital records over the decades, reduced change management for medical users, but failed to make use of the potential of organizing digital data. We proposed a method to create clinical dashboards to increase the usability of information in the medical records. Official clinical guidelines were studied by a working group, including dashboard target users. Necessary clinical concepts contained in the medical records were identified according to the clinical context and finally, dedicated technical tools with standard terminologies were used to represent categories of information. We used this method to generate and implement a dashboard for sepsis. The dashboard was found to be appropriate and easy to use by the target users. [ABSTRACT FROM AUTHOR]

The interdependency of structure and mechanical features of a cohesive powder packing is on current scientific focus and far from being well understood. Although the Discrete Element Method provides a well applicable and widely used tool to model powder behavior, non-trivial contact mechanics of micron-sized particles demand a sophisticated contact model. Here, a direct comparison between experiment and simulation on a particle level offers a proper approach for model validation. However, the simulation of a full scale shear-tester experiment with micron-sized particles, and hence, validating this simulation remains a challenge. We address this task by down scaling the experimental setup: A fully functional micro shear-tester was developed and implemented into an X-ray tomography device in order to visualize the sample on a bulk and particle level within small bulk volumes of the order of a few micro liter under well-defined consolidation. Using spherical micron-sized particles (30 μm), shear tests with a particle number accessible for simulations can be performed. Moreover, particle level analysis allows for a direct comparison of experimental and numerical results, e.g., regarding structural evolution. In this talk, we focus on density inhomogeneity and shear induced heterogeneity during compaction and shear deformation. [ABSTRACT FROM AUTHOR]

The detailed understanding of particle flow is of special interest from the academic point of view and crucial for a safe and reliable process design. Due to poor flowability and heterogeneous bulk structures, the handling of fine and cohesive powders is particularly challenging. Recently, high resolution X-ray microtomography (XMT) has proved to be a reliable tool for analysing powder structures on bulk and particle level. This study now presents a complementary approach of micro-scale experiments and XMT analysis to improve the general understanding of particle flow. Centrepiece of the experimental investigation is a novel micro shear tester (μST) for very small powder samples (volumes from 0.005 to 0.1 mL), which has been integrated into a high resolution XMT system. By combining μST and XMT it is possible to extract detailed 3D images of precisely compacted and sheared powder samples. A SiO2 powder consisting of spherical, adhesive particles (x50,3 ≈ 11,2 μm) and a limestone powder consisting of irregular shaped particles (x50,3 ≈ 4,8 μm) are scanned before and after various shear and compaction tests. A detailed analysis of the sample microstructure reveals important information on the particle network and the bulk structure. The impact of the test procedure on mesoscopic heterogeneities and shear zones inside the sample is discussed. Moreover, the measurement of yield loci in the novel μST is presented.
