This paper discusses the need and leveraging potential of formal modeling and web technology for progressing towards the goal of automating the establishment, maintenance and assessment of the completeness of traceability and the consistency of the requirements. The generic Augmented Lifecycle Space method, devised in an earlier paper, is applied a...
The assessment and improvement of the satisfaction of traceability requirements during the development of software in general and of safety-critical software in particular is demanding and costly. The special requirements are reflected in software process related general and industry specific standards and the popular agile approaches as well. It i...
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...
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 stri...
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 pe...
The paper gives a summary of 2014 year results in the topic of physiological modeling and control achieved by the Physiological Controls Group of the Obuda University. The presentation is integrated in the tradition established years ago at IEEE INES conferences and 2014's IEEE SACI conference summarizing the latest results obtained by the group. F...
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...
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...
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 (contro...
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, lon...
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 tim...
