1. 1. Designing Self-Adaptive Software Systems with Reuse

   Författare :Nadeem Abbas; Jesper Andersson; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Variability; Uncertainty; Self-Adaptation; Software Reuse; Software Design; Methodology; Domain Engineering.; Computer Science; Datavetenskap; Data- och informationsvetenskap; Computer and Information Sciences Computer Science; Software Technology; Programvaruteknik;

   Sammanfattning : Modern software systems are increasingly more connected, pervasive, and dynamic, as such, they are subject to more runtime variations than legacy systems. Runtime variations affect system properties, such as performance and availability. The variations are difficult to anticipate and thus mitigate in the system design. LÄS MER

3. 2. New Constructions for Competitive and Minimal-Adaptive Group Testing

   Författare :Muhammad Azam Sheikh; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strict group testing; disjoint pools; randomization; competitive group testing; minimal-adaptive group testing; exact bounds; competitive ratio;

   Sammanfattning : Group testing (GT) was originally proposed during the World War II in an attempt to minimize the \emph{cost} and \emph{waiting time} in performing identical blood tests of the soldiers for a low-prevalence disease. Formally, the GT problem asks to find $d\ll n$ \emph{defective} elements out of $n$ elements by querying subsets (pools) for the presence of defectives. LÄS MER

4. 3. Engineering Competitive and Query-Optimal Minimal-Adaptive Randomized Group Testing Strategies

   Författare :Muhammad Azam Sheikh; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; learning by queries; combinatorial search; competitive ratio; randomization; pooling design; group testing; linear program;

   Sammanfattning : Suppose that given is a collection of $n$ elements where $d$ of them are \emph{defective}. We can query an arbitrarily chosen subset of elements which returns Yes if the subset contains at least one defective and No if the subset is free of defectives. The problem of group testing is to identify the defectives with a minimum number of such queries. LÄS MER

5. 4. Intelligence-Driven Software Performance Assurance

   Författare :Mahshid Helali Moghadam; Markus Bohlin; Mehrdad Saadatmand; Markus Borg; Björn Lisper; Antonia Bertolino; Mälardalens universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : Software performance assurance is of great importance for the success of software products, which are nowadays involved in many parts of our life. Performance evaluation approaches such as performance modeling, testing, as well as runtime performance control methods, all can contribute to the realization of software performance assurance.

7. 5. Towards a distributed programming environment based on incremental compilation

   Författare :Peter Fritzson; Warren Teitelman; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : A Programming Environment is a system that provides computer assistance during software development and maintenance. The primary objective of this work concerns practically usable methods and tools in the construction of incremental and integrated programming environments that provide good support for debugging and testing of programs in a distributed context, in our case a host-target configuration.
