Zusammenfassung In dieser Arbeit stellen wir unsere Überlegungen und Erfahrungen bei der Werkzeugunterstützung für iterative Modernisierungsprozesse von formularbasierten Informationssystemen vor. Nachdem wir die Anforderungen für ein Werkzeug skizzieren, stellen wir deren beispielhafte Implementierung im Werkzeug SOPTIM CQM vor. Der zweite Teil beschäftigt sich mit unseren Erfahrungen bei der ...

begin{abstract} In this paper, we introduce an iterative method for amenable semigroup of non expansive mappings and infinite family of non expansive mappings in the frame work of Hilbert spaces. We prove the strong convergence of the proposed iterative algorithm to the unique solution of a variational inequality, which is the optimality condition for a minimization problem. The results present...

It is of interest in various contexts to nd approximate feasible points to problems that have equality, inequality and bound constraints. For example, in exhaustive search algorithms for global optimization , it is of interest to construct bounds around approximate feasible points, within which a true feasible point is proven to exist. In such exhaustive search algorithms, the approximate feasi...

This paper is a summary of a talk given during the ”Joint Advanced Students School 2005“ in St. Petersburg. Iterative Equalization or Turbo-Equalization is an iterative technique which concatenates the processes of equalization and decoding according to the Turbo-Principle[1]. In conventional receivers, these two processes are separated and only pass hard decisions instead of soft decisions. It...

In this study, N-methyl-N'propyltrimethoxysilylimidazoliummodified LUS-1 and MCM-48 nonoporous materials were prepared and employed as adsorbent for removing Reactive Blue-19 from aqueous solutions.LUS-1 and MCM-48 were made based on the previous procedure and modified with N-methyl-N'propyltrimethoxysilylimidazolium chloride. XRD analyses did not show any lattice alteration between modified an...

Intensity modulation and direct detection (IM/DD) is a cost-effective optical communication strategy which finds wide applications in fiber communication, free-space optical communication, and indoor visible light communication. In IM/DD, orthogonal frequency division multiplexing (OFDM), originally employed in radio frequency communication, is considered as a strong candidate solution to comba...

Agile Entwicklungsmethoden versprechen durch die iterative Entwicklung von Anforderungen, Bedürfnisse von Kunden genauer treffen zu können als Ansätze des „klassischen“ Software-Engineering. Ausgehend von drei verschiedenen Pro jekten bei einem deutschen Versicherer berichten wir über unsere Erfahrungen mit der Ermittlung und Entwicklung von Anforderungen. Wir beschreiben das Fördern von Verbin...

This paper is concerned with a technique for solving Volterra integral equations in the reproducing kernel Hilbert space. In contrast with the conventional reproducing kernel method, the Gram-Schmidt process is omitted here and satisfactory results are obtained.The analytical solution is represented in the form of series.An iterative method is given to obtain the approximate solution.The conver...
