Abstract Background In acute respiratory distress syndrome (ARDS), non-ventilated perfused regions coexist with non-perfused ventilated within lungs. The number of unmatched might reflect ARDS severity and affect the risk ventilation-induced lung injury. Despite pathophysiological relevance, ventilation perfusion are not routinely assessed at bedside. aims this study were to quantify bedside by electrical impedance tomography (EIT) investigating their association mortality in patients...
This tutorial uses design patterns to present techniques for implementing effective and efficient resource management in a system. The is based on the third volume of POSA (pattern-oriented software architecture) series. presents thorough introduction along with two case studies which are applied domains ad hoc networking mobile radio networks. presented independent any implementation technique, such as .NET, Java or C++, even though examples given C++. grouped by different areas address...
Electrical impedance tomography is clinically used to trace ventilation related changes in electrical conductivity of lung tissue. Estimating regional pulmonary perfusion using still a matter research. To support clinical decision making, reliable bedside information needed. We introduce method robustly detect based on indicator-enhanced and validate it by dynamic multidetector computed two experimental models acute respiratory distress syndrome. The injury was induced sublobar segment the...
Code is modularized, for many reasons, including making it easier to understand, change, and verify. Aspect-oriented programming approaches extend the kind of code that can be enabling modularization crosscutting code. We conducted an inquisitive study better understand kinds software developers encounter how manage this tracked eight participants: four from industry academia. Each participant was currently evolving a non-trivial system. interviewed these participants three times about...
Although existing CORBA specifications, such as Real-time and Messaging, address many end-to-end quality of service (QoS) properties, they do not define strategies for configuring these properties into applications flexibly, transparently, adaptively. Therefore, application developers must make configuration decisions manually explicitly which is tedious, error-prone, often suboptimal. the recently adopted Component Model (CCM) does a standard framework packaging deploying software...
This paper explains the challenges we experienced when introducing a software product family approach in Siemens business groups. Our vision is complete and easily accessible cookbook with advice on how to start such an approach. In first attempt, identified collection of more or less successful best practices. On suggestions open questions are going present this paper, search validation by practitioners field
This paper summarizes our experience with introducing feature modeling into a product line for imaging and therapy systems in the Siemens Healthcare Sector. Determining negotiating scope that spans several business units their own economic goals is challenging. Feature offers good way to do variability/commonality analysis complex lines. A precondition identification of all features supporting line. To identify these features, we developed method systematically deriving model top down based...
Existing middleware specifications, such as Real-Time CORBA and Messaging, address many quality-of-service (QoS) properties by defining policies that control connection multiplexing, request priority, queuing order, routing, dependability. They do not, however, define strategies for configuring these QoS into applications flexibly, transparently, adaptively. Application developers must therefore make configuration decisions manually. This process is tedious error-prone, suboptimal complex...
Asynchronous invocations are needed in the context of distributed object frameworks to prevent clients from blocking during remote invocations. Popular Web service offer only synchronous (over HTTP). An alternative is messaging protocols but these implement a different communication paradigm. When client asynchrony not supported, developers have build asynchronous on top invocation facility. But this tedious, error-prone, and might result styles used within same application. We present...
This paper documents the experiences of Siemens Healthcare in mastering challenges when transitioning a large-scale dispersed platform development organization to Agile. Product Line Engineering aims at increasing productivity through reuse, but since strategic reuse requires up-front decisions, is also seen as heavy weight and process driven. Agile on other hand perceived lightweight, change friendly, same time neglecting long term planning. With this we want report our experience combining...
Small-signal gain at line center for a group of lines has been utilized to deduce the time dependence rotational tempreature in pulsed high-pressure CO2 laser systems. Attempts extract additional information on excited-state population densities is compromised by uncertainties vibration-rotation interaction. Anomalies small-signal P20, P28, and R14 10.4-μ band are observed.
Patterns and pattern languages offer a practical means for distributed system developers to both gain deeper understanding of the middleware they use convey their knowledge about it The proposed Remoting language offers systematic way reuse software models, designs, implementations extend, integrate, customize, or build object solutions. This has rich dependencies with other patterns from related domains, including networking, concurrency, resource management.
Abstract Heart Rate Variability studies are a known measure for the autonomous control of heart rate. In special situations, its interpretation can be ambiguous, since respiration has major influence on rate variability. For this reason it often been proposed to Variability, while subjects breathing at constant That way spectral is known. work we propose remove respiratory from and parameters gain free controlled signal. The component in signal detected characterized. Subsequently effect...

Patterns have become part of the software development mainstream. They're available for all phases process, including analysis, documentation, design, testing, and configuration management, to name a few. In addition documenting current status patterns, this special issue will reflect critically on discuss achievements pattern community. This article is patterns.
