We investigated the relationship between the duration of percutaneous central venous catheterization and the occurrence of catheter-related complications in critically ill children by survival analysis techniques. Data were collected prospectively and analyzed for infectious and noninfectious complications from 379 pediatric patients in whom central venous(More)
In a prospective, 45-month study, we compared the complication rates of percutaneously placed femoral and nonfemoral central venous catheters in critically ill pediatric patients. Forty-one percent of the 395 central venous catheters placed during this interval were femoral. Noninfectious complications were recognized for 2.5% of femoral catheters and 2.1%(More)
The proposed concept of a Cellular Transport System shows the possibilities to increase the flexibility and changeability of facility logistics systems and enhances the ease of use of complex decentralized control systems. This contribution shows how to enhance these issues compared to conventional facility logistics systems, e.g. static conveyors, by using(More)
In this paper, we present a novel concept for the detection of loading positions of parcels or bins on a pallet to enable automated order picking using knowledge about the packing pattern model. The approach comprises (1) a new combination of pattern model data and PMD-camera-generated point clouds and (2) a novel concept of RFID data management using a(More)
The fast growing of Distributed Generation (DG) in European electricity networks, lead to challenges of different nature. Due the fast growth of market split of Distributed Energy Resources (DER), today's electric power system of centrally located generation, transmission networks and distribution networks is expected to evolve into a new configuration. The(More)
Power quality monitoring has advanced to an important tool for system evaluation. The increased amount of recorded data requires more sophisticated analysis methods. The paper describes the development and operation of a system for automated classification of power quality events. Different to existing approaches the proposed system introduces a new(More)
