In spite of themodularizationbene!ts supportedby theAspect-Orientedprogrammingparadigm, di"erent usability issues have hindered its adoption.#e decoupling between aspect de!nitions and base code, and the compile-time weaving mechanism adopted by di"erent AOP languages, require developers to manage the consistency between base code and aspect code themselves.#ese mechanisms create opportunities ...

Periodic refactoring of a large source code often becomes a necessity especially for long-lived projects. In order to increase maintainability and extensibility of such projects, design pattern based refactoring can be seen as an emerging alternative. Manual inspection of source code to find candidate spots where patterns can be introduced is time consuming. Therefore automated tools can help i...

With the expected growth in mobile robotics the demand for expertise to develop robot control code will also increase. As end-users cannot be expected to develop this control code themselves, a more elegant solution would be to allow the end-users to teach the robot by demonstrating the task. In this paper we show how route learning tasks may be “translated” directly into robot control code sim...

This paper describes a method for profiling large systems software on a Linux platform. Based on runtime profiling results, the bottleneck source code gets analyzed statically, thus identifying the poor algorithms that caused the low performance. Employing of various tools used to profile the case study application leads to the conclusion of increasing importance for integrating code analysis w...

We present MONITORMETHOD, a tool which helps Java programmers gain insight in the behavior of their applications. MONITORMETHOD instruments the Java application and relates hardware performance monitors (HPMs) to the methods in the Java application’s source code. We present a detailed case study showing that linking microprocessor-level performance characteristics to the source code is helpful ...

Assuming the Java version of a program provides good performance, many programmers are interested in using Java as a replacement for many traditional programming languages because of the portability of Java and the extensive runtime libraries. However, in many cases the performance of the Java code requires improvement before it is acceptable. Profiling provides an effective means of identifyin...

Antiviral software systems (AVSs) have problems in identifying polymorphic variants of viruses without explicit signatures for such variants. Alignment-based techniques from bioinformatics may provide a novel way to generate signatures from consensuses found in polymorphic variant code. We demonstrate how multiple sequence alignment supplemented with gap penalties leads to viral code signatures...

Consider a connected undirected graph G = (V,E) and a subset of vertices C. If for all vertices v ∈ V , the sets Br(v) ∩ C are all nonempty and pairwise distinct, where Br(v) denotes the set of all points within distance r from v, then we call C an r-identifying code. We give general lower and upper bounds on the best possible density of r-identifying codes in three infinite regular graphs.
