Web Services technology provides software developers with a wide range of tools and models to produce innovative distributed appli- cations. After the initial diusion of the standard technology the atten- tion of the developers has focused on the ways to secure the information flows between clients and service providers. For this purpose several st...
Many language resources are being shared as web services to process data on the Internet. As dataset size keeps growing, language services are experiencing more big data problems, such as the storage and processing overheads caused by the huge amounts of multilingual texts. Parallel execution and cloud technologies are the keys to making service in...

This paper presents a comprehensive solution to build a distributed system of medical devices in high acuity environments. It is based on the concept of a Service Oriented Medical Device Architecture. It uses the Devices Profile for Web Services as a transport layer protocol and enhances it to the Medical Devices Profile forWeb Service (MDPWS) to meet medical requirements. By applying the ISO/IEEE 11073 Domain Information Model, device data can be semantically described and exchanged by means of a generic service interface. Data model and service interface are subsumed under the Basic Integrated Clinical Environment Specification (BICEPS). MDPWS and BICEPS are implemented as part of the publically available openSDC stack. Performance measurements and a real world setup prove that openSDC is feasible to be deployed in distributed systems of medical devices. © David Gregorczyk, Stefan Fischer, Timm Busshaus, Stefan Schlichting, and Stephan Pöhlsen.

Hierzu gehört u.a. eine Spezifikation, die es erlaubt, sicherheitskritische Kontextinformationen wie etwa den Wert eines zweiten Kanals zu übermitteln[5].Die entwickelte Referenzimplementierung von BICEPS wurde für die Java SE 6 implementiert und umfasst sowohl eine Bibliothek für Dienstnutzer als auch für Dienstanbieter. Das verwendete MDPWS-Framework verwendet als DPWS-Implementierung das JMEDS-Framework[6]. ...
The number of devices in an operation room (OR) and the complexity of the components and the overall system increases continuously. Today's vendor-dependent integrated ORs are expensive and not able to handle this complexity because they can only form isolated solutions. Thus a device communication for medical devices among each other and to medical information systems has to be based on open and vendor-independent standards. In this paper we will present new standards for networked Point-of-Care medical devices that will be part of the IEEE 11073 family of standards. A service-oriented device communication is defined by means of an architecture definition, a transport specification called Medical Devices Profile for Web Services (MDPWS), and a Domain Information & Service Model. The new system will make the complexity of a comprehensive OR integration manageable and thereby improve patient's safety. The focus of this paper is on MDPWS that enables a device communication for medical requirements and safety issues, like safe data transmission that will typically be used for safe remote control (dual channel and safety context), data streaming, and compact transmission. The suitability of the concept has been shown by a demonstrator with over 20 real world OR devices from more than 10 vendors.
