In order to evaluate ATM for future DAQ systems and remote control systems as well as for a high speed picture archiving and communications system for medical images, Forschungszentrum Julich has build up a pilot system for the evaluation of ATM and standard low cost multimedia systems. It is a heterogeneous multivendor system containing a variety of switches and desktop solutions, employing different protocol options of ATM. The tests conducted in the pilot system revealed major difficulties regarding stability, interoperability and performance. The paper presents motivations, layout and results of the pilot system. Discussion of results concentrates on performance issues relevant for realistic applications, e.g., connection to a RAID system via NFS over ATM},

  abstract  = {Single-photon emission tomography (SPET) with the amino acid analogue l-3-[123I]iodo-α-methyl tyrosine (IMT) is helpful in the diagnosis and monitoring of cerebral gliomas. Radiolabelled amino acids seem to reflect tumour infiltration more specifically than conventional methods like magnetic resonance imaging and computed tomography. Automatic tumour delineation based on maximal tumour uptake may cause an overestimation of mean tumour uptake and an underestimation of tumour extension in tumours with circumscribed peaks. The aim of this study was to develop a program for tumour delineation and calculation of mean tumour uptake which takes into account the mean background activity and is thus optimised to the problem of tumour definition in IMT SPET. Using the frequency distribution of pixel intensities of the tomograms a program was developed which automatically detects a reference brain region and draws an isocontour region around the tumour taking into account mean brain radioactivity. Tumour area and tumour/brain ratios were calculated. A three-compartment phantom was simulated to test the program. The program was applied to IMT SPET studies of 20 patients with cerebral gliomas and was compared to the results of manual analysis by three different investigators. Activity ratios and chamber extension of the phantom were correctly calculated by the automatic analysis. A method based on image maxima alone failed to determine chamber extension correctly. Manual region of interest analysis in patient studies resulted in a mean inter-observer standard deviation of 8.7\%±6.1\% (range 2.7\%-25.0\%). The mean value of the results of the manual analysis showed a significant correlation to the results of the automatic analysis (r = 0.91, P<0.0001 for the uptake ratio; r = 0.87, P<0.0001 for the tumour area). We conclude that the algorithm proposed simplifies the calculation of uptake ratios and may be used for observer-independent evaluation of IMT SPET studies. Three-dimensional tumour recognition and transfer to co-registered morphological images based on this program may be useful for the planning of surgical and radiation treatment.},

  year      = {1998},
  abstract  = {An BaTiO3 Keramik als Modellsubstanz und mit Nd:YAG- und Excimer-Lasern wurde die Mikrostrukturierung von Gr{\"u}nk{\"o}rperpreßlingen, deren Schrumpfungsverhalten beim Sintern und die Mikrostrukturierung von gesinterten Keramiken untersucht. F{\"u}r die bessere Vergleichbarkeit wurden alle keramischen Folien, Preßlinge und Sinterwerkstoffe im Rahmen des Projektes hergestellt. Die Nd:YAG Laserbearbeitung erfolgte mit einem Rasterverfahren, bei dem der fokussierte Strahl mit Hilfe eines Scanners und eines Umlenkspiegels entlang der Bearbeitungskontur gef{\"u}hrt wurde. Bei der Excimer Laserbearbeitung wurden die Strukturen ohne Relativbewegung zwischen Strahlquelle und Bearbeitungsobjekt durch die Abbildung einer Maske erzeugt. Mit dem Nd:YAG Laser (Wellenl{\"a}nge 1,06 µ m) war eine abtragende Bearbeitung nur bei den Gr{\"u}nk{\"o}rpern, nicht aber bei den gesinterten Keramiken m{\"o}glich. Mit dem Excimer Laser (Wellenl{\"a}nge 248 nm) konnten dagegen sowohl Gr{\"u}nk{\"o}rper als auch gesinterte Keramiken strukturiert werden. Wenn die Genauigkeitsanforderungen nicht unter ± 10 µm liegen, die Bearbeitungskonturen m{\"o}glichst geradlinig sind und der Anteil der zu bearbeitenden Fl{\"a}che klein ist, kann mit Nd:YAG-Lasern eine effiziente Mikrostukturierung von keramischen Gr{\"u}nk{\"o}rpern durchgef{\"u}hrt werden. Strukturierte Gr{\"u}nk{\"o}rper k{\"o}nnen reproduzierbar und unverzerrt zu keramischen Bauteilen gesintert werden. Mit Excimer-Lasern wird eine h{\"o}here Genauigkeit und Qualit{\"a}t bei der Bearbeitung von Gr{\"u}nk{\"o}rpern und Keramiken erreicht. Die Bearbeitungseffizienz l{\"a}sst sich durch eine hohe Pulswiederholfrequenz und durch die simultane Bearbeitung großer Fl{\"a}chen steigern. Das f{\"u}r Excimer-Laserstrahlung zweckm{\"a}ßige Abbildungsverfahren hat besondere Vorteile, wenn ein fl{\"a}chiger Abtrag mit komplexen Strukturen verwirklicht werden soll, wobei Toleranzen und Reproduzierbarkeiten von besser als ± 5 µm realisiert werden konnten. Die Mikrostrukturierung mit Excimer-Lasern ist an Gr{\"u}nk{\"o}rpern und an gebrannten Keramiken gleichermaßen m{\"o}glich. Die Abtragsraten liegen bei Gr{\"u}nk{\"o}rpern mit 0,2 µm pro Puls zwar um ca. 50\% h{\"o}her als bei Keramiken, es ist jedoch zweifelhaft, ob dieser Vorteil den gr{\"o}ßeren prozeßtechnischen Aufwand bei der Bearbeitung von Gr{\"u}nk{\"o}rpern rechtfertigen kann.},

Nicht selten werden „Vorgehensmodelle"definiert, jedoch nicht konsequent oder nicht mit dem erw{\"u}nschten Erfolg eingesetzt. Die Modellierung der Entwicklungsabl{\"a}ufe garantiert nicht deren effektive und effiziente Umsetzung; dazu ist ein „Prozeßmanagement"erforderlich. Die verf{\"u}gbaren Prozeßmanagementans{\"a}tze eignen sich f{\"u}r unterschiedliche Anwendungsfelder und Organisationskulturen, sind dementsprechend auch auf die Softwareentwicklung {\"u}bertragbar, adressieren jedoch nur bedingt den zentralen Erfolgsfaktor betrieblicher Softwareentwicklung: die Zufriedenheit der Anwender als Kunden der Softwareentwicklung. Der Schl{\"u}ssel f{\"u}r erfolgreiche Softwareentwicklungsprozesse liegt nicht im Prozeßmanagement allein, sondern in dessen Ausgestaltung mit Blick auf den Kunden. Ansatzpunkte f{\"u}r ein kundenorientiertes Softwareprozeßmanagement sind die Etablierung einer Kunden/Lieferantenbeziehung, die Fokussierung und Differenzierung der Entwicklungsprozesse, die Benutzerinvolvierung, Simultaneous Engineering und die gezielte Identifikation, Integration und Kooperation der „Stimme des Kunden"und der „Stimme des Ingenieurs". Die Bewertung kundenorientierter Softwareprozesse wird diskutiert und Schlußfolgerungen f{\"u}r Forschung und Praxis skizziert.},

  abstract  = {This paper addresses the pixel based classification of three dimensional objects from arbitrary views. To perform this task a coding strategy, inspired by the biological model of human vision, for pixel data is described. The coding strategy ensures that the input data is invariant against shift, scale and rotation of the object in the input domain. The image data is used as input to a class of self organizing neural networks, the Kohonen-maps or self-organizing feature maps (SOFM). To verify this approach two test sets have been generated: the first set, consisting of artificially generated images, is used to examine the classification properties of the SOFMs; the second test set examines the clustering capabilities of the SOFM when real world image data is applied to the network after it has been preprocessed to be invariant against shift, scale and rotation. It is shown that the clustering capability of the SOFM is strongly dependant on the invariance coding of the images.},
