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 measured at(More)
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 among(More)
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 sensitive(More)
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, a major(More)

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 multitenancy 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 common way in(More)

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, time can be saved. Benefits can also be ergonomic improvements offering hands-free operations during daily tasks. Hands-free operations are of special interest in(More)
Since the late 90s the idea of mass customization in industry is present. The main goal is to handle the consumer demand for customized products. Recent developments in research, engineering and technology enable industries to move from profitable linear assembly lines to profitable non-linear, dynamic assembly lines to satisfy such a demand. Industry 4.0,(More)
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 can have(More)
