Vergleichende Untersuchung an Schwebfliegen (Diptera, Syrphidae) extensiv genutzter Wiesen

Die Schwebfliegengemeinschaften extensiv genutzter Wiesen wurden anhand drei verschiedener Methoden untersucht. Dabei wurden einige überregional interessante Nachweise erbracht. Während der Phase qroßer Blütenentwicklungen wurden mit den Fallen im Verhältnis zur tatsächlichen Aktivitätsdichte viel zu wenige Schwebfliegen erfaßt. Der Lebensraum Wiese hat eine große Bedeutung für Schwebfliegen, dies gilt insbesondere für extensiv genutzte Feuchtwiesen.The syrphid associations in extensively used meadows were scrutinized applying three different methods. The analysis has led to some interesting results of more than regional importance. During the phase of maximum flowering, the number of syrphids caught by the traps was far too small compared to the actual activity density. Meadows represent a biosphere of considerable importance to syrphids, this being particularly true for extensively used humid meadows

Service composition based on SIP peer-to-peer networks

Today the telecommunication market is faced with the situation that customers are requesting for new telecommunication services, especially value added services. The concept of Next Generation Networks (NGN) seems to be a solution for this, so this concept finds its way into the telecommunication area. These customer expectations have emerged in the context of NGN and the associated migration of the telecommunication networks from traditional circuit-switched towards packet-switched networks. One fundamental aspect of the NGN concept is to outsource the intelligence of services from the switching plane onto separated Service Delivery Platforms using SIP (Session Initiation Protocol) to provide the required signalling functionality. Caused by this migration process towards NGN SIP has appeared as the major signalling protocol for IP (Internet Protocol) based NGN. This will lead in contrast to ISDN (Integrated Services Digital Network) and IN (Intelligent Network) to significantly lower dependences among the network and services and enables to implement new services much easier and faster. In addition, further concepts from the IT (Information Technology) namely SOA (Service-Oriented Architecture) have largely influenced the telecommunication sector forced by amalgamation of IT and telecommunications. The benefit of applying SOA in telecommunication services is the acceleration of service creation and delivery. Main features of the SOA are that services are reusable, discoverable combinable and independently accessible from any location. Integration of those features offers a broader flexibility and efficiency for varying demands on services. This thesis proposes a novel framework for service provisioning and composition in SIP-based peer-to-peer networks applying the principles of SOA. One key contribution of the framework is the approach to enable the provisioning and composition of services which is performed by applying SIP. Based on this, the framework provides a flexible and fast way to request the creation for composite services. Furthermore the framework enables to request and combine multimodal value-added services, which means that they are no longer limited regarding media types such as audio, video and text. The proposed framework has been validated by a prototype implementation
