On the derivation of closed-form expressions for displacements, strains and stresses inside a poroelastic inclusion

This note provides the derivation of closed-form expressions for elastic displacements, strains, and stresses inside an inclusion. Jansen et al. (2019) and Wu et al. (2021) obtained correct expressions for the stresses inside an inclusion, but their derivation of these expressions contained mistakes. In this note, the correct derivation of...

Adinda: A knowledgeable, browser-based IDE

In practice, many people have to work together to develop and maintain a software system. However, the programmer’s key tool, the Integrated Development Environment (IDE), is a solo-tool, serving to help individual programmers understand and modify the system. Such an IDE does not leverage the knowledge other team members may have of the design...

A controlled experiment for program comprehension through trace visualization

Accepted version for publication in IEEE Transactions on Software Engineering. Software maintenance activities require a sufficient level of understanding of the software at hand that unfortunately is not always readily available. Execution trace visualization is a common approach in gaining this understanding, and among our own efforts in this...

Execution Trace Analysis through Massive Sequence and Circular Bundle Views

Preprint of article published in: Journal of Systems and Software (Elsevier), 81 (12), 2008; doi:10.1016/j.jss.2008.02.068 An important part of many software maintenance tasks is to gain a sufficient level of understanding of the system at hand. The use of dynamic information to aid in this software understanding process is a common practice...

An Assessment Methodology for Trace Reduction Techniques

Preprint of paper published in: ICSM 2008 - IEEE International Conference on Software Maintenance, 28 September-4 October 2008; doi:10.1109/ICSM.2008.4658059 Program comprehension is an important concern in software maintenance because these tasks generally require a degree of knowledge of the system at hand. While the use of dynamic analysis in...

A Systematic Survey of Program Comprehension through Dynamic Analysis

Preprint of paper published in: IEEE Transactions on Software Engineering, 35 (5), 2009; doi:10.1109/TSE.2009.28 Program comprehension is an important activity in software maintenance, as software must be sufficiently understood before it can be properly modified. The study of a program's execution, known as dynamic analysis, has become a common...

On Large Execution Traces and Trace Abstraction Techniques

Preprint of paper published in: Journal of Software Maintenance and Evolution (Wiley), 2008 Program comprehension is an important concern in the context of software maintenance tasks because these activities generally require a certain degree of knowledge of the system at hand. Although the use of dynamic analysis for information gathering has...

Trace Visualization Using Hierarchical Edge Bundles and Massive Sequence Views

One way of gaining understanding of a software system is the analysis of dynamic information, i.e., program execution traces. A problem regarding the analysis of such traces is the fact that these are often extremely large: hundreds of thousands and even millions of calls within a single trace are no exception. To aid a user in navigating and...

Dynamic Analysis Techniques for the Reconstruction of Architectural Views

Gaining an understanding of software systems is an important discipline in many software engineering contexts. It is essential that software engineers are assisted as much as possible during this task, e.g., by using tools and techniques that provide architectural views on the software at hand. This Ph.D. research addresses this issue by...

Understanding Execution Traces Using Massive Sequence and Circular Bundle Views

The use of dynamic information to aid in software understanding is a common practice nowadays. One of the many approaches concerns the comprehension of execution traces. A major issue in this context is scalability: due to the vast amounts of information, it is a very difficult task to successfully find your way through such traces without...

Visualizing Testsuites to Aid in Software Understanding

Agile software development methods such as eXtreme Programming have brought renewed attention to testing during the software development process, both as a quality assurance method and as a form of live documentation. It is for this reason that a software system’s testsuite is an ideal starting point for gaining knowledge about its inner...

Flexwater: Inventarisatie van bronnen, berging, zuivering en infrastructuur

De Nederlandse drinkwaterproductie is georganiseerd volgens een succesvolle formule, waarin schaalvergroting en clustering van productielocaties een belangrijke rol spelen. Diverse ontwikkelingen maken het noodzakelijk om de huidige inrichting van de watervoorziening tegen het licht te houden: klimaatverandering, onzekere watervraag, terrorisme,...

Constant-amplitude tests on plain concrete in uniaxial tension and tension-compression

This research report is the continuation of Stevin Laboratory Report No. 5-81-7 "Fatigue of plain concrete in uniaxial tension and in alternating tension-compression" [1], in which test set-up, loading equipment and preliminary results have been described. The present report deals with the total set of constant-amplitude tests on concrete loaded...

Fatigue of plain concrete in uniaxial tension and in alternating tension-compression experiment and results

This research program deals with fatigue of plain concrete subjected tocyclic uniaxial tensile loadings or alternating uniaxial compression-tension.In the main program more than 250 constant amplitude tests at a frequency of 6Hz have been performed. One concrete composition was investigated (averagecompressive strength: 50 N/mm² and average...
