Die strikte visuelle Fuhrung eines Werkers lasst diesen seine taglichen Pick-Aufgaben in einem Logistiklager schneller und fehlerfreier absolvieren, als ihm dies ohne die Unterstutzung einer Datenbrille moglich ware. Picavi konnte mit diesem Ansatz fur viele Kunden die intralogistischen Prozesse effizienter gestalten. So tritt die Pick-by-Vision-Losung ihren Siegeszug bei der Kommissionierung an und das 2013 gegrundete Unternehmen zahlt zu den Vorreitern dieser Entwicklung. Dieser Beitrag legt dar, warum der sogenannte Hands-Free-Ansatz und das Aufnehmen der Informationen uber das Auge, die Arbeitsablaufe in den Logistikzentren zu optimieren weis. Nicht zuletzt werden hier auch die Verbindungsmoglichkeiten zwischen den noch immer unschlagbaren kognitiven Fahigkeiten des Menschen und den technischen Assistenzsystemen, die seine Tatigkeit erleichtern, am Beispiel der Datenbrille skizziert.

Condition-based maintenance (CBM) has emerged as a proactive strategy for determining the best time for maintenance activities. In this paper, a case of a milling process with imperfect maintenance at a German automotive manufacturer is considered. Its major challenge is that only data with missing labels are available, which does not provide a sufficient basis for classical prognostic maintenance models. To overcome this shortcoming, a data science study is carried out that combines several analytical methods, especially from the field of machine learning (ML). These include time-domain and time–frequency domain techniques for feature extraction, agglomerative hierarchical clustering and time series clustering for unsupervised pattern detection, as well as a recurrent neural network for prognostic model training. With the approach developed, it is possible to replace decisions that were made based on subjective criteria with data-driven decisions to increase the tool life of the milling machines. The solution can be employed beyond the presented case to similar maintenance scenarios as the basis for decision support and prognostic model development. Moreover, it helps to further close the gap between ML research and the practical implementation of CBM.

To date, there is still no IFDH approved dental hygienist (DH) education model in Germany. Nevertheless, opportunities to complete vocational DH education courses have substantially increased within the last two decades. However, the content and quality of these courses vary greatly and are difficult to survey. The purpose of this article therefore was to present an overview of the education programmes offered in Germany as of March 2017. A formal request was sent to all education establishments for details of such courses, and a systematic internet search was performed covering the DH education topic in Germany. Ten vocational education programmes were found, most of them organized by local dental chambers. One private provider offers a Bachelor Degree in Dental Hygiene on completion of a course which runs over 2 or 3ys. Details of contents, objectives and concise ratings or comparisons of the various courses are scarce, although in principle all should meet the same quality standards. For dental hygiene students, patients and dentists, it is hard and unsatisfactory to get a clear overview of the types and the quality of DH education which can be achieved in Germany. A solution for this dilemma would appear to be essential. However, due to the peculiarities of German legislation as well as the complex sphere of vested interests, it is impossible to predict if or when the situation will change for the better.

PRAP-CVD has been developed to deposit intrinsically conducting polymer films in order to control the interface of electrodes in devices. As case study PEDOT film has been investigated.

Conventional central power generation shows a high electrical efficiency, hut the transmission of the energy to the consumer is hindered by distribution losses. Decentralized combined heat and power (CHP) generation in proximity to the customer is an alternative to reduce transmission losses. Based on a natural gas-fired micro-CHP system, a liquid fuel burner system is developed. The modification of the natural gas system for operation with light fuel oil (no. 2) is the focus of this project. An innovative vaporization technique, i.e., cool flame vaporization, is used to create a homogenous fuel-air mixture. The combustion of the fuel-air mixture is surface stabilized, using the surface burner of the natural gas system. Different atomization techniques and nitrogen oxide reduction concepts, such as air staging and exhaust gas recirculation, were evaluated. By fulfilling stringent emission targets and safe operation in the complete power range, the concept of micro-CHP aims to achieve an efficient use of limited resources.

In den letzten Jahren hat sich der Wettbewerb in allen Branchen und auf allen Märkten drastisch verschärft. Die Gründe dafür liegen in der Globalisierung der Märkte, in dem damit verbundenen Preisdruck, und im sogenannten Single Sourcing begründet. Der Begriff des Single Sourcing beschreibt die Tendenz in Unternehmen, die Zahl ihrer Lieferanten deutlich zu reduzieren. Ziel des Single Sourcing ist es, die Beschaffung einfacher und übersichtlicher zu gestalten und über die höheren Umsatzanteile der verbleibenden Lieferanten stärkeren Druck auf die Preise auszuüben.
