Projektmanagement im Mittelstand? Häufig Fehlanzeige, seufzen Beobachter. Mit modernen Methoden der Projektabwicklung, wie sie sich seit vielen Jahren etwa in Konzernen bewährt haben, wollen mittelständische Unternehmen wenig zu tun haben. Doch Vorsicht! Professor Uwe Braehmer warnt vor Pauschalurteilen. Einige Mittelständler beherrschen meisterhaft die Klaviatur des Projektmanagements. Andere erkennen derzeit neue Geschäftschancen durch Projektmanagement. Und wieder andere brauchen ein dem Mittelstand speziell angepasstes Projektmanagement. Professor Uwe Braehmer weiß: „Auf viele mittelständische Geschäftsführer wirkt Projektmanagement zu akademisch und zu groß dimensioniert.“ Bedarfsgerecht gestaltet könne es im Mittelstand eine wesentlich breitere Akzeptanz finden.
Routing Attacks are a serious threat to communication in tactical MANETs. TOGBAD is a centralised approach, using topology graphs to detect such attacks. In this paper, we present TOGBAD's newly added wormhole detection capability. It is an adaptation of a wormhole detection method developed by Hu et al. This method is based on nodes' positions. We adapted it to the specific properties of tactical environments. Furthermore, we present simulation results which show TOGBAD's performance regarding the detection of wormhole attacks.
Hochschulbibliotheken haben heutzutage neben der traditionellen Aufgabe der Literaturversorgung und Informationsversorgung auch die Aufgabe, über ihre Website im Internet präsent zu sein und sich dort als zentraler Informationsanbieter zu positionieren. Die Webauftritte haben dabei die Funktionen als Zugangspunkt und Vermittlungsstelle für Informationen sowie als Werbemittel bzw. Instrument der Öffentlichkeitsarbeit. Im Hinblick auf die immer stärkere Benutzerorientierung der Bibliotheken werden die Webangebote von fünf Universitätsbibliotheken und einer Fachhochschulbibliothek nach diversen Kriterien analysiert: es wird herausgearbeitet, welche Inhalte auf den Websites zu finden sind, die Struktur wird näher betrachtet, ebenso wie die Navigationsmöglichkeiten, die Sprache und Textgestaltung und das Design.
The usage of link quality based routing metrics significantly improves the quality of the chosen paths and by that the performance of the network. But, attackers may try to exploit link qualities for their purposes. Especially in tactical multi-hop networks, routing may fall prey to an attacker. Such routing attacks are a serious threat to communication. TOGBAD is a centralised approach, using topology graphs to detect routing attacks. In this paper, we enhance TOGBAD with the capability to detect fake link qualities. We use a Challenge/Response method to estimate the link qualities in the network. Based on this, we perform plausibility checks for the link qualities propagated by the nodes in the network. Furthermore, we study the impact of attackers propagating fake link qualities and present simulation results showing TOGBAD's detection rate.
Spectral surveys provide the only way to determine the full molecular inventory of an object and hence build a comprehensive view of the state of the molecular gas and its role in star formation and the structure and evolution of the ISM. Of course spectral surveys also provide the most efficient method of identifying new and unexpected species that have to be include in the chemical networks. The most extensive and complete survey of an extragalactic system has been the continuous spectral survey from 129 GHz to 175 GHz carried out by Martín et al. (2006) toward NGC253. This first spectral line surveys at 2 mm towards the prototypical starbursts galaxies NGC253 have shown an unexpected chemical richness.

The roadmap for quality and innovation through open educational practices has been conceived as a number of steps, a conceptual document, which can be used by organisations, leaners or professionals in order to improve their open educational practices. After the development of the core concept of the OPAL project, the guidelines for OEP, it became clear that these guidelines, would have to play an important part on the roadmap exercise, because they represent the very essence of how to foster and stimulate open educational practices. The roadmap therefore is meant to be an instrument, a tool which helps the different stakeholders to use the guidelines for their own context and purpose.
