Petrescu, Stefan (author)Modern systems generate a tremendous amount of data, making manual investigations infeasible, hence requiring automating the process of analysis. However, running automated log analysis pipelines is far from straightforward, due to the changing nature of software ecosystems caused by the constant need to adapt to user requirements. In practice,...master thesis 2022

Schoenmaker, Melle (author)This paper presents the use of a heuristic solution method to improve the process of creating a conjunctive normal form (CNF) encoding of and finding optimal solutions to instances of the resource-constrained project scheduling problem with logical constraints (RCPSP-Log).<br/><br/>The RCPSP is an optimisation problem consisting of a set of...bachelor thesis 2022

Zhao, Yi (author), Liang, K. (author), Zhao, Yanqi (author), Yang, Bo (author), Ming, Yang (author), Panaousis, Emmanouil (author)An algorithm substitution attack (ASA) can undermine the security of cryptographic primitives by subverting the original implementation. An ASA succeeds when it extracts secrets without being detected. To launch an ASA on signature schemes, existing studies often needed to collect signatures with successive indices to extract the signing key....journal article 2022

Schouten, David (author)One of the preferred features of plastic is its high durability. This merit is its main disadvantage in the natural environment. When poorly disposed of, plastic waste can enter rivers from surface waters and subsequently end up in the ocean. Here, plastic spreads out over the entire ocean and ultimately ends in ocean gyres....master thesis 2021

Paduli, Francisco (author)The Automated Parameter Determination project aims to provide advanced geotechnical models parameters from in-situ tests in a transparent and flexible process. The framework was initially developed for coarse-grained soils, and it was needed to be expanded to all types of common soils. This report presents the expansion of the APD database to...master thesis 2021

Symeonidis, Pandelis (author)System behavior models are highly useful for the developers of the system as they aid in system comprehension, documentation, and testing. Even though methods to obtain such models exist, e.g. profiling, tracing, source code inference and existing log-based inference methods, they can not successfully be applied to the case of large, real-time...bachelor thesis 2021

Werthenbach, Thomas (author)An essential step of software development is obtaining an understanding of the behaviour of a system. Accurate state models of system behaviour might help software developers build such an understanding. There exist several techniques for automatically inferring models on system behaviour using log analysis, but these do not scale well for...bachelor thesis 2021

Mikalauskas, Liudas (author)Logging is a common practice in software development that assists developers with the maintenance of software. Logging a system optimally is a challenging task, thus Li et al. have proposed a state-of-the-art log recommendation model. However, no further attempts exist to improve the model or reproduce their results using different training data...bachelor thesis 2021

Brandirali, Tommaso (author)Large software systems today require increasingly complex models of their execution to aid the analysis of their behavior. Such execution models are impractical to compile by hand, and current approaches to their automated generation are either not generalizable or not scalable enough. This paper addresses this problem with a new approach based...bachelor thesis 2021

Lyrakis, Kostas (author)Logging is a common practice of vital importance that enables developers to collect runtime information from a system. This information is then used to monitor a system's performance as it runs in production and to detect the cause of system failures. Besides its importance, logging is still a manual and difficult process. Developers rely on...bachelor thesis 2021

van Berkel, Sam (author)Performing user interface studies and logging user interactions is commonplace in the Interactive Information Retrieval field (IIR). As a result, the LogUI framework was developed to make logging such interactions an easier task. However, this framework does not come with any visualization tool, requiring the researcher to analyze their data...bachelor thesis 2021

Kochar, Rahul (author)Cross Browser Inconsistencies (XBI) were created when different browser vendors implemented their products without deciding upon common protocols for interoperability. It is hard to pinpoint these inconsistencies with precision because of a lack of a good tool. Here we show how to use a web-based event logger (LogUI) to find XBI at a granular...bachelor thesis 2021

van Dijk, Hugo (author)Logging user interactions allows researchers to study user behavior in web applications. The LogUI framework can be used to log user interactions on virtually any web application. This framework misses two vital features, a screen capture feature and a dashboard for statistical data analysis and visualization for use in web-based experiments...bachelor thesis 2021

van Wijk, Paul (author)Web-based interaction logging is an important concept for understanding user behavior on web-pages. LogUI is a powerful modern framework for logging a user's interactions. Integrating such a framework in web-pages requires the construction of configuration objects to define selectors that indicate which elements on a web-page should be under...bachelor thesis 2021

Sijsenaar, Jochem (author)We inspect the behavior of the probability that a weighted sum of random variables with log-normal tails is greater than its expected value. Under the right conditions for the weights and the variance being set to 1; we were able to bound a suitable transformation of this probability with the upper bound being a fixed factor of the square root...bachelor thesis 2021

Maxwell, D.M. (author), Hauff, C. (author)Studies involving user interfaces typically involve the capturing and recording (logging) of key user interactions between the user and the system being examined. However, anecdotal evidence suggests that researchers often implement their own logging infrastructure-sometimes in a piecemeal fashion-which can lead to numerous implementation...journal article 2021

Barros Cândido, J. (author), Haesen, Jan (author), Aniche, Maurício (author), van Deursen, A. (author)Logging is a development practice that plays an important role in the operations and monitoring of complex systems. Developers place log statements in the source code and use log data to understand how the system behaves in production. Unfortunately, anticipating where to log during development is challenging. Previous studies show the...conference paper 2021

Barros Cândido, J. (author), Aniche, Maurício (author), van Deursen, A. (author)Modern software development and operations rely on monitoring to understand how systems behave in production. The data provided by application logs and runtime environment are essential to detect and diagnose undesired behavior and improve system reliability. However, despite the rich ecosystem around industry- ready log solutions, monitoring...journal article 2021

Maxwell, D.M. (author), Hauff, C. (author)Logging user interactions is fundamental to capturing and subsequently analysing user behaviours in the context of web-based Interactive Information Retrieval (IIR). However, logging is often implemented within experimental apparatus in a piecemeal fashion, leading to incomplete or noisy data. To address these issues, we present the LogUI...conference paper 2021
