  • This chapter discusses the problematic nature of interfacial sciences when constrained to the mesoscale. Interfacial sciences are trapped between the atomistic and the three- dimensional bulk regimes - the mesoscale. We experience a breakdown of phenomenological descriptions used to characterize macrosystems. Furthermore, submicrometer systems with their fractal-like dimension cannot be adequately described with quantum or molecular interaction theories. The challenge of describing the mesoscale for the...

  • Today the term big data draws a lot of attention, but behind the hype there's a simple story. For decades, companies have been making business decisions based on transactional data stored in relational databases. Beyond that critical data, however, is a potential treasure trove of non-traditional, less structured data: weblogs, social media, email, sensors, and photographs that can be mined for useful information. Decreases in the cost of both storage and compute power have made it feasible to collect this data - which would have been thrown away only a few years ago.

  • Over the past decade, many countries have been upgrading their water monitoring systems and their data collection efforts, supported with new information technologies and web‑based communication. A review of the information demands arising from OECD work, shows that important gaps still remain. The quality of water data currently available at national and international level is insufficient to effectively support integrated water management and water policies.

  • In order to develop an in-depth understanding of the subject while at the same time reducing the complexity of our research endeavor, we decided to distinguish three related research questions that will be explained in more detail below. First, we were interested in the direct influences of regulatory actors on strategy formation – more specifically, on corporate re- source allocations. While this helped us to identify if there was an influence of regulatory actors, the second step involved examining how strategy formation was impacted.

  • Hence, all else equal, one could expect global retail banks to have a preference for subsidiarization, while global universal banks for branching. 11 The subsidiary structure may work well for retail banks, as it may benefit from a local management team that is fully accountable for the performance of an affiliate focused on local retail operations. There is a benefit to a management team that has a deep understanding of the local market and a greater ability to obtain local funding.

  • In the range of high strain rates, the mechanical behaviour of materials is characterized by an increased strain rate sensitivity, by increasing effects of mass inertia forces and by the adiabatic character of the deformation process. For the relation between stress, strain and strain rate, empirical formulae are now mostly replaced by material laws based on structural mechanical models, whose parameters are to be determined by adequate systematic methods. Also special effects such as the influence of strain rate on...

  • Multibody simulation consists of analyzing the dynamic behavior of a system of interconnected bodies comprised of flexible and/or rigid components. The bodies may be constrained with respect to each other via a kinematically admissible set of constraints modeled as joints. These systems can represent an automobile, a space structure with antenna deployment capabilities, an aircraft as an assemblage of rigid and flexible parts, a robot with manipulator arms, and so on. In all such cases, the components may undergo large rotation, large displacement, and finite strain effects....
