In software development application lifecycle management (ALM) systems are used to support the development process. As these products are tailored for best fitting the applied programs and their actual usage is diverse. Often, this means that products of different vendors are applied, which reduce the reachability between different artefacts and the overall consistency of the system. In this paper...
Modern software development is unimaginable without the help of Application lifecycle management systems (ALMs) due to the heavy documentation and communication needs, especially in safety-critical developments. In this paper the idea of Augmented Lifecycle Space is presented together with its use and benefits. The main target of application is to enhance traceability and consistency throughout the...
The effective use of (human) resources and a mature product assumes the application of a software development life cycle (SDLC) management system which actively supports the process of development. A well-adjusted SDLC system is a prerequisite in safety-critical developments, such as the development of medical devices. Otherwise, the intensive documentation needed proving the correct and safe operation...
The software development lifecycle management is a crucial aspect of software development, as it defines significantly the effectiveness of development and the maturity of the final product. A suitable management system is especially important in safety critical development, such as the development of medical devices, as these developments have to be well documented to prove the safe operation of...
With blood purification the life of a person suffering by kidney malfunction can be saved or the quality of her/his life can be increased. This is the purpose of hemodialysis machines, where the blood of the patient is filtered (cleared) in an extracorporeal tube system. Here peristaltic pumps are responsible for the fluid transport, where the strict control is a serious need, in order to maintain...
Hemodialysis machines have an important role in the support and maintenance of life functions, wherein the strict control of peristaltic pumps is a serious need. The current paper targets to present soft computing methods, which can be applied for the peristaltic pumpcontrol problem, demonstrating their applicability on real systems as well. The performances of these controllers are compared with...
In hemodialysis systems the control of peristaltic pumps can be vital as these machines support and maintain life functions. In this paper different soft computing approaches are compared for the strict control of peristaltic pumps. An adaptive fuzzy logic and an adaptive neuro-fuzzy inference system are examined then compared with a classical PID controller. A fast controller is sought, which is...
In hemodialysis machines peristaltic pumps are responsible for the transfer of fluids. These pumps can only deliver the solutions with significant error, due to the deviation of the pump head and due to production errors. Previous work focused on system identification and fluid flow control by a PID controller. In this paper the goal is to replace the PID controller with an adaptive fuzzy controller...
Following the tradition established at previous IEEE INES conferences, this paper presents the results achieved by the Physiological Controls Group of Óbuda University in the field of physiological control last year (2013). The application target was focused on diabetes (artificial pancreas), tumor (antiangiogenic therapy), and hemodialysis (control of peristaltic pumps).
Peristaltic pumps are positive replacement pumps, commonly used in fluid transports. These pump does not contaminate the transported fluid, they are undemanding and ideal for shear-sensitive and aggressive fluids. Through their wide spectrum of use, there are many variants of these pumps based on their special needs, such as high pressure need, long tubing lifetime or low pressure deviation. The object...
In hemodialysis machines peristaltic pumps are responsible for the transfer of fluids. The main characteristic of these pumps is that they can transport the solutions with significant error. That depends on the tube segment deviation caused through the production. Due to the fact that the medical fluid represents sometimes drugs and in the same time it is required to control the fluid balance of the...
