JAVADAPTOR : unrestricted dynamic updates of Java applications

In dieser Arbeit wird mit JAVADAPTOR ein Ansatz präsentiert, der die statisch getypte Programmiersprache Java um die Möglichkeit erweitert, Programme zur Laufzeit und ohne die genannten Einschränkungen zu aktualisieren. Das vorgestellte Konzept kombiniert das schemaverändernde Nachladen von Klassen mit Referenzaktualisierungen auf der Basis von Java HotSwap, Containern und Proxies. Zentrale Beiträge der Arbeit sind detaillierte Beschreibungen der Konzepte und deren Implementierung, sowie der Nachweis der Praxvistauglichkeit der Lösung anhand verschiedener Fallstudien. Weiterhin wird untersucht, ob die präsentierte Lösung Einschränkungen bezüglich Flexibilität, Performanz, Plattform, Programmarchitektur oder Änderungsgranularität unterliegt.

Assessment of Autonomic Function by Phase Rectification of RRInterval Histogram Analysis in Chagas Disease

Background:In chronic Chagas disease (ChD), impairment of cardiac autonomic function bears prognostic implications. Phase‑rectification of RR-interval series isolates the sympathetic, acceleration phase (AC) and parasympathetic, deceleration phase (DC) influences on cardiac autonomic modulation.Objective:This study investigated heart rate variability (HRV) as a function of RR-interval to assess autonomic function in healthy and ChD subjects.Methods:Control (n = 20) and ChD (n = 20) groups were studied. All underwent 60-min head-up tilt table test under ECG recording. Histogram of RR-interval series was calculated, with 100 ms class, ranging from 600–1100 ms. In each class, mean RR-intervals (MNN) and root-mean-squared difference (RMSNN) of consecutive normal RR-intervals that suited a particular class were calculated. Average of all RMSNN values in each class was analyzed as function of MNN, in the whole series (RMSNNT), and in AC (RMSNNAC) and DC (RMSNNDC) phases. Slopes of linear regression lines were compared between groups using Student t-test. Correlation coefficients were tested before comparisons. RMSNN was log-transformed. (α < 0.05).Results:Correlation coefficient was significant in all regressions (p < 0.05). In the control group, RMSNNT, RMSNNAC, and RMSNNDCsignificantly increased linearly with MNN (p < 0.05). In ChD, only RMSNNAC showed significant increase as a function of MNN, whereas RMSNNT and RMSNNDC did not.Conclusion:HRV increases in proportion with the RR-interval in healthy subjects. This behavior is lost in ChD, particularly in the DC phase, indicating cardiac vagal incompetence.
