Enterprise portals have become the backbone for the integration of a large number of different applications, content, and services (Smith, 2004). Nowadays, electronic business can hardly be imagined without the use of these portals as central entry points. At the same time, companies become more and more aware that portal projects are complex, timeand cost-consuming, with a high risk of failing...

OBJECTIVE Integration of robotic surgical technology into skull base surgery is limited due to minimum angle requirements between robotic tools (narrow funnel effect), steep angle of approach, and instrumentation size. The objectives of this study were to systematically analyze surgical approach portals using a computer model, determine optimal approaches, and assess feasibility of the derived ...

The World Wide Web represents one of the most profound developments that has accompanied the evolution of the Internet. It is truly a global library. Information on the Web is increasing exponentially, and mechanisms to extract information from it have become an engaging field of research. While search engines have been doing an admirable job in finding information, the emergence of Web portals...

Patient portals provide patients with access to a provide-managed electronic health record (EHR). They may provide an interesting approach to increase patient empowerment. The objective of this paper is to provide a first overview of the state-of-the-art and the impact of patient portals. Based on a systematic literature search, we identified five evaluation studies on patient portals. These st...

We present a scalable and reliable framework for Semantic Portals which is an extension of our existing SEAL approach. We illustrate the instantiation of our framework by the real-world example of a heterogeneous and distributed infrastructure of Semantic Portals, viz. the portal of our institute AIFB, the OntoWeb.org portals and the KM-Vision.org portal. The approach relies on the application ...

The Portals 3.3 data movement interface was developed at Sandia National Laboratories in collaboration with the University of New Mexico over the last ten years. Portals is intended to provide the functionality necessary to scale a distributed memory parallel computing system to thousands of nodes. Previous versions of Portals ran on several large-scale machines, including a 1024-node nCUBE-2, ...

Proper portal placement is critical to performing good diagnostic and therapeutic arthroscopy. When the portals are positioned improperly, visualization can be impaired, making diagnosis and treatment more difficult. Three main anterior portals are available in arthroscopy of the ankle: anteromedial, anterolateral, and anterocentral. Posterior portals are also routinely used in ankle arthroscop...

Portal: Portale charakterisieren Verbindungen zwischen verschiedenen Elementen einer Site. Der AbstractPortalType (siehe Abbildung 4.7) legt die Eigenschaften für verschiedene konkrete Portale fest. Jedes AbstractPortal ist über ein belongsTo-Element genau einem AbstractBuildingInformation-Element zugeordnet. Über ein oder mehrere linksToElemente ist das AbstractPortal mit einem oder mehreren a...
