Abstract:

Multi-objective ant colony optimization (MOACO) algorithms have shown promising results for various multi-objective problems, but they also offer a large number of possible design choices. Often, exploring all possible configurations is practically infeasible. Recently, the automatic configuration of a MOACO framework was explored and was shown to result in new state-of-the-art MOACO algorithms for the bi-objective traveling salesman problem. In this paper, we apply this approach to the bi-objective bidimensional knapsack problem (bBKP) to prove its generality and power. As a first step, we tune and improve the performance of four MOACO algorithms that have been earlier proposed for the bBKP. In a second step, we configure the full MOACO framework and show that the automatically configured MOACO framework outperforms all previous MOACO algorithms for the bBKP as well as their improved variants.

Abstract: The talk deals with two questions related to software testing. The first is: Why more testing should be taught? Complex systems and demands for higher software quality require software quality assurance, and generally, more efforts on software testing. The amount of software testing continues to grow. The related literature estimates that software testing effort is 50-60% of the total development effort. We summarize experience of teaching software testing by application of the ISTQB (International Software Testing Qualifications Board) syllabi in the master study programme of software engineering. The second question is: Which theory of software testing do we have to teach? We focus on the approach of Goodenough and Gerhart. We are seeking further theories (Gödel) for their possible inclusion into the syllabi of software testing courses.

Der Rückblick zum TEWI-Kolloquium von Dr. Giorgio Brajnik, Università di Udine am 25.01.2013 beinhaltet die Folien:

Abstract: The talk will provide an outline of major model-driven engineering approaches to user interface design: we will cover data-driven approaches as well as task-driven ones, highlighting what are the key requirements

illustrated, and the equation Controller + Model = View will be discussed.
The overall claim will be that UML-IDEA supports a clear meaning for the term “interaction design” whose operationalization should bring a number of advantages: rapid and flexible mix-fidelity prototyping, retargeting of the user interface, usability metrics and development of functional test cases.

CV: Giorgio Brajnik is assistant professor in Computer Science at the University of Udine, Italy. His current interests are design, development and quality assessments of user interfaces, with an emphasis on accessibility, usability and user experience. In the past he worked on tools for testing accessibility, as well as information retrieval user interfaces and qualitative modeling of dynamical systems. He currently teaches “Usage centered design of web applications” and “User experience”. He has been invited several times as visiting professor or panelist, and is member of many conference program committees as well as being a reviewer for different journals. In the past he served as scientific advisor for companies; in July 2012 he cofounded and is President of Interaction Design Solutions, a spin-off of the University of Udine that develops software for rapid prototyping and multiplatform deployment of user interfaces based on innovative model-based development practices. The company also provides consultancy services regarding usability and usage-centered design.

Abstract: Cloud computing and the increasing variety of services offered over the internet have created interesting new challenges for security, ranging far beyond classical goals like confidentiality, integrity, authenticity or availability. Protection of data nowadays extends data confidentiality to the protection of identities (ownership and user behavior) as well. This duty of anonymization is mostly up to security infrastructures and new cryptographic primitives. The respective infrastructure design processes cannot be reduced to a humble assembly of cryptographic building blocks, but must cover for aspects of risk management and the interplay of security components. Handling these matters calls for a deep understanding of how cryptography supports and determines system security. Besides, security cannot be achieved by cryptography alone, and techniques from

cryptographic primitives.

CV: Stefan Rass works in the System Security Research Group at the Alpen-Adria-Universität Klagenfurt. He received a PhD in mathematics for his research in information-theoretic security and risk management, with applications in Quantum Cryptography. His main research interests cover classical cryptography, as well as the design of security infrastructures and security risk management.
