• This work presents a slim-floor configuration which increases its fire protection. new beam is called “Internally Fire Protected Slim-Floor Beam”. The IFP-SFB based on strategy that does not need maintenance. results in up to 30–60 min of additional resistance. composite concrete-steel fully integrated into the floor depth was developed at beginning 1990s. very good behaviour during event bec...

We consider a stochastic differential equation in a Hilbert space with time-dependent coefficients for which no general existence result ∗Supported in part by the RFBR project 07-01-00536, the Russian–Japanese Grant 0801-91205-JF, the Russian–Chinese Grant 06-01-39003, ARC Discovery Grant DP0663153, the DFG Grant 436 RUS 113/343/0(R), SFB 701 at the University of Bielefeld †Supported in part by...

This paper reports a new method for making high aspect ratio Single Crystalline Silicon (SCS) microstructures om multi layer substrates using Chemical Mechanical Polishing (CMP), Silicon Fusion Bonding (SFB) and Reactive Ion Etching (NE) techniques. First Si-Si02-PolySi-Si02-Si sandwich wafers were fabricated using CMP and SFB. Then microstructures were fabricated on these sandwich wafers using...

Queue management schemes at the routers and congestion avoidance schemes at the end points cooperate to provide good congestion solutions in computer networks. While queue management schemes are still being developed, research on congestion avoidance has come a long way to serve the bandwidth requirement of the networks. Because of considerable lack on the evaluation research work, there is no ...

Im Rahmen des seit Januar 2003 von der Deutschen Forschungsgemeinschaft geförderten Sonderforschungsbereichs 627 Umgebungsmodelle für mobile kontextbezogene Systeme 1 werden an der Universität Stuttgart grundlegende Forschungsarbeiten zur Erstellung, Nutzung, Aktualisierung und Ausgestaltung digitaler Weltmodelle und zu deren Nutzung in kontextbezogenen Informationssystemen durchgeführt. Forsch...

We propose a model-independent multivariate sequential procedure to monitor changes in the vector of componentwise unconditional variances in a sequence of p-variate random vectors. The asymptotic behavior of the detector is derived and consistency of the procedure stated. A detailed simulation study illustrates the performance of the procedure confronted with different types of data generating...

BACKGROUND Artemia (Crustacea, Anostraca), also known as brine shrimp, are typical inhabitants of extreme environments. These hypersaline environments vary considerably in their physicochemical composition, and even their climatic conditions and elevation. Several thalassohaline (marine) environments along the Colombian Caribbean coast were surveyed in order to contribute to the knowledge of br...

Comprehensive reuse and systematic evolution of reuse artifacts as proposed by the Quality Improvement Paradigm (QIP) require an integrated management of (potentially reusable) experience data as well as project-related data. This demonstration presents an approach exploiting object-relational database technology to implement a QIP-driven reuse repository. Our SFB-501-Reuse-Repository is design...
