Humans are an essential part of the manufacturing domain. In factory environments the support to humans can offer benefits. Such benefits can for example be monetary as processes are accelerated and time can be saved. Benefits can also be ergonomic improvements offering hands-free operations during daily tasks. Hands-free operations are of special...

Harsh and hazardous working conditions can push humans to their limits when completing their tasks. Smart Textiles, wearables and 3D printing technology enable us to form Human-Centric Cyber-Physical Systems (HC-CPSs) that put the human in the center of the system design. HCCPSs aim to increase operational safety by monitoring for example health pa...

One goal of the Industry 4.0 initiative is to improve knowledge sharing among and within production sites. A fast and easy knowledge exchange can help to reduce costly down-times in factory environments. In the domain of automotive manufacturing, production line down-times cost in average about $1.3 million per hour. Saving seconds or minutes have...

One goal of the Industry 4.0 initiative is to improve horizontal and vertical knowledge sharing among industries. Horizontal sharing allows companies to exchange knowledge across different sites whereas vertical sharing allows the exchange of knowledge across hierarchical structures within a site. Sharing knowledge especially about incidents result...

Software-as-a-Service is a delivery model whose basic idea is to provide applications to the customer on demand over the Internet. SaaS thereby promotes multi-tenancy as a tool to exploit economies of scale. This means that a single application instance serves multiple customers. However, a major drawback of SaaS is the customers' hesitation of sha...

Advances in development and deployment of mobile business applications (MBAs) based on the hybrid Web approach (hybrid MBAs) create new possibilities for enterprises to mobilize their business processes (BPs). Despite the fact that variability has a natural appearance in complex environments among different enterprises, current development tools fo...

Software-as-a-Service (SaaS) is a delivery model whose basic idea is to provide applications to the customer on demand over the Internet. Thereby, SaaS promotes multi-tenancy as a tool to exploit economies of scale. A major drawback of SaaS is the customers' hesitation of sharing infrastructure, application code, or data with other tenants. The com...

Software-as-a-Service (SaaS) is a delivery model whose basic idea is to provide applications to the customer on demand over the Internet. In contrast to similar but older approaches, SaaS promotes multi-tenancy as a tool to exploit economies of scale. This means that a single application instance serves multiple customers. However, a major throwbac...

Immer mehr Unternehmen öffnen ihren Innovationsprozess und binden aktiv externe Mitarbeiter, Partner, Lieferanten, Kunden und Forschungseinrichtungen in diesen Entwicklungsprozess mit ein. Somit können sowohl externe als auch interne Wege genutzt werden, um neue Produkte und Lösungen zu generieren. Diese Öffnung des Innovationsprozesses bezeichnet...

In many ways cloud computing is an extension of the service-oriented computing (SOC) approach to create resilient and elastic hosting environments and applications. Service-oriented Architectures (SOA), thus, share many architectural properties with cloud environments and cloud applications, such as the distribution of application functionality amo...

With recent advances in development and deployment of mobile business applications (MBAs) based on the hybrid Web approach (hybrid MBAs) enterprises around the world well recognize new potentials to mobilize their business processes (BPs). Variability has a natural appearance in complex environments of different enterprises, where even similar BPs...

Context-aware computing has been an intensively researched topic for years already. Consequently, there exists a plethora of usage scenarios for context-aware applications as well as several approaches for the modeling and management of a user’s context information, many of which focus on the efficient and scalable distribution of the latter. With...

Vor zehn Jahren hieß Mobilität, jedem Mitarbeiter ein Diensthandy zur Verfügung zu stellen. Diese einfache und effektive Lösung genügt jedoch angesichts der aktuellen Technologieentwicklung nicht mehr. Ein Mobiltelefon hat heute mehr Rechenleistung und Funktionalitäten als ein damaliges Notebook und die dazugehörige Breitbandabdeckung erlaubt prakt...

Mobile Apps sind Programme, die auf modernen Handys, sogenannten Smartphones, ausgeführt werden. Wurden nach einer Studie des Analystenhauses Gartner [1] im Jahr 2010 schon 8 Milliarden Apps auf die Smartphones aus dem Netz geladen, so steht der eigentliche Boom noch bevor: Bis Ende 2014 sollen 185 Milliarden App-Downloads erfolgen. Allerdings adre...

Software-as-a-Service (SaaS) is a delivery model whose basic idea is to provide applications to the customer on demand over the Internet. In contrast to similar but older approaches, SaaS promotes multi-tenancy as a tool to exploit economies of scale. This means that a single application instance serves multiple customers. On the one hand, however,...

The integration of mobile devices into business processes is a challenging but promising task. We designed a system that shows the possibility of constructing software systems that accomplish the difficult achievement of a system that simplifies tasks for businesses as well as for their customers. We designed a very simple and straight-forward work...

X-ray diffraction patterns have been recorded from a single layer of purple membrane ( approximately 50 A thickness) at the air/water interface in a Langmuir trough. Grazing-incidence X-ray diffraction is demonstrated to be a promising method for obtaining structural information on membrane proteins under physiological conditions. The method is so...

Quasielastic incoherent neutron scattering as a tool to study picosecond equilibrium fluctuations was used to investigate the dynamical properties of two retinal proteins, rhodopsin and bacteriorhodopsin. Upon absorption of a photon by the retinal chromophore both proteins undergo a sequence of different intermediate states. As known from numerous...

By neutron scattering experiments and time-resolved absorption spectroscopy we have investigated picosecond equilibrium fluctuations and the kinetics of the photocycle of bacteriorhodopsin (BR) in the purple membrane (PM). Natural PM samples composed of 75% BR (w/w) and 25% lipid (w/w) as well as delipidated PM having only 5% lipid (w/w) were measu...

Neutron diffraction and time-resolved laser-spectroscopic experiments on the light-driven proton-pump bacteriorhodopsin revealed the location of water molecules and their functional importance. About seven water molecules in the proton pathway across this membrane protein were determined at 15% rel. humidity in the ground state.
