Aufgrund der zunehmenden Individualisierung von Produkten mit hoher Variantenvielfalt stellt die aktive Integration von intelligenten Produkten in die Prozesssteuerung eine hilfreiche Möglichkeit zur Nutzung von Flexibilisierungs- und Rationalisierungspotenzialen in der Fertigung dar. In diesem Beitrag wird eine Methode zur Analyse und Bewertung der Einsatzpotenziale von Produktklassen mit unterschiedlichen Fähigkeiten vorgestellt und anhand eines praktischen Anwendungsfall evaluiert.
Seit einiger Zeit ergänzt eSports das Portfolio vieler Sponsoren im Sport. Durch Teilhaberschaften sowie Partnerschaften mit wichtigen Organisationen fassen die Marken in der eSports-Landschaft Fuß. Während die Kommunikationsarbeit mit Medien und Fans im Rahmen der konventionellen Sportarten über Jahre erprobt ist, ist die PR in eSports für Unternehmen neu.
Der vorliegende Beitrag untersucht die Anforderungen an die PR in eSports. Diese werden anhand der Auswertung einer quantitativen Umfrage unter eSports-Fans identifiziert. Die Ergebnisse belegen die Existenz von bedeutenden Unterschieden in den Anforderungen an eine erfolgreiche PR in eSports.
A device including a first and second monitoring unit, the first monitoring unit detecting a first voltage potential and the second monitoring unit detecting a second voltage potential, the monitoring units comparing the first voltage potential and the second voltage potential to the value of the supply voltage and activate a control unit as a function of the comparisons, the control unit determining a switching point in time of a second power transistor, and an arrangement being present which generates current when the second power transistor is being switched on, the current changing the first voltage potential, and the control unit activates a first power transistor when the first voltage potential has the same value as the supply voltage, so that the first power transistor is de-energized.
Increasing concerns regarding the world´s natural resources and sustainability continue to be a major issue for global development. As a result several political initiatives and strategies for green or resource-efficient growth both on national and international levels have been proposed. A core element of these initiatives is the promotion of an increase of resource or material productivity. This dissertation examines material productivity developments in the OECD and BRICS countries between 1980 and 2008. By applying the concept of convergence stemming from economic growth theory to material productivity the analysis provides insights into both aspects: material productivity developments in general as well potentials for accelerated improvements in material productivity which consequently may allow a reduction of material use globally. The results of the convergence analysis underline the importance of policy-making with regard to technology and innovation policy enabling the production of resource-efficient products and services as well as technology transfer and diffusion.
Long-term stability of membranes in membrane distillation operation is a problem nowadays which prevents the industrial breakthrough of this separation process. Fouling or slow pore wetting are the basic reasons for this.
Membrane distillation membranes were made by NIPS process rendering the membrane asymmetrically to achieve low permeation resistance and pores which can be over coated with polyelectrolyte polymers thus leading to thermopervaporation membranes. Those membranes prohibit pore wetting and may strongly reduce resorption of organic substances on for membrane distillation typically used hydrophobic surfaces thus leading to longterm operation stability in dewatering including stable membrane cleaning.
Asymmetric PVDF membranes have been coated with cation exchange polyelectrolyte leading to a very thin, defect-free layer which has a high permeation rate for water due to the domain structure of phase-separated hydrophilic and hydrophobic three-dimensional structures.
Health monitoring in a home environment can have broader use since it may provide continuous control of health parameters with relatively minor intrusiveness into regular life. This work aims to verify if it is possible to replace the typical in some sleep medicine areas subjective questioning by an objective measurement using electronic devices. For this purpose, a study was conducted with ten subjects, in which objective and subjective measurement of relevant sleep parameters took place. The results of both measurement methods were evaluated and analyzed. The results showed that while for some measures, such as Total Time in Bed, there is a high agreement between objective and subjective measurements, for others, such as sleep quality, there are significant differences. For this reason, currently, a combination of both measurement methods may be beneficial and provide the most detailed results, while a partial replacement can already reduce the number of questions at the subjective measurement by measurement through electronic devices.
There is no denying that organizations, whether domestic or global, whether educational, governmental, or business, are undergoing rapid transformation. However, what is causing it? Prompted by the need to remain relevant and competitive, organizations constantly try to reinvent themselves. Those that do not, according to the laws of economics, will simply serve no purpose and will eventually cease to exist. Regardless of sector or industry, an organization's success pivots around its human talent. Hence, it is crucial to manage it and cultivate certain traits, knowledge, and skills. In today's global economy, organizations are more interconnected than ever before and thus the challenges they face require that employees possess not only expert knowledge, problem-solving, cross-cultural, and cross-functional teaming skills, but also good communications skills and agile thinking.
Fußball-Weltmeisterschaften sind immer auch Materialschlachten der Ausrüster. Manchmal ist sogar die Rede vom "Krieg der Triktos und Schuhe". Der vorliegende Beitrag zeigt, welcher Sportartikelhersteller bei der WM 2014 in Brasilien und im globalen Kampf um die Vorherrschaft auf die richtigen Mannschaften und Verkaufsstrategien setzt.
