The Impact of Test Case Clustering on Comprehending Automatically Generated Test Suites

Software testing, a critical phase in the software development lifecycle, is often hindered by the time-intensive and costly manual creation of test cases. While automating test case generation could mitigate these challenges, its adoption in the industry has been limited due to difficulties in comprehending the generated test cases. To address...

Empirical Study on Test Generation Using GitHub Copilot

Writing unit tests is a crucial task in the software development lifecycle, ensuring the correctness of the software developed. Due to its time-consuming and laborious nature, it is, however, often neglected by software engineers. Numerous automatic test generation tools have been devised to ease unit testing efforts, but these test generation...

Design and integration of an off-shore off-grid system and an on-land system for comparison on photovoltaic performance

The purpose of this thesis research was to perform a photovoltaic (PV) performance assessment and comparison between a small-scale land-based PV system and an off-shore off-grid floating PV system. Also from this research design guidelines for off-grid off-shore floating PV systems were developed. The research experiment was carried out in The...

Identifying moral antecedents of decision-making in discrete choice models

Discrete Choice Models are valuable tools for quantitative decision-making analysis: they allow analysts to draw behavioural conclusions from data, better understand and predict choices, and evaluate policies. However, up until recently, they had a blind spot for morality. Moral values often play an essential role in decision-making; fairness or...

SAD: State machine-based Anomaly Detection in User Behavior

Over the past centuries, cybercrime has constantly grown. Among the most popular attacks against companies are phishing emails that especially gained popularity for threat actors to use as a tool during the COVID-19 pandemic. By changing the working environment, most communication channels between employees shifted from personal conversations...

Empirical Essays in Artificial Intelligence Ethics

As Artificial Intelligence (AI) becomes increasingly important in modern society, there is a pressing need to address the ethical issues associated with these technologies. AI Ethics is a necessary endeavor to capitalize on the benefits of AI while minimizing its risks. However, it faces important challenges related to normative urgency, multi...

Empirical study of GANITE’s robustness to hidden confounders

An empirical study is performed exploring the sensitivity to hidden confounders of GANITE, a method for Individualized Treatment Effect (ITE) estimation. Most real world datasets do not measure all confounders and thus it is important to know how crucial this is in order to obtain comparable predictions. This is explored through the removal of...

From Trunk-Based to Merge Requests: A Field Study at Adyen

Many development models exist, but finding which one is the right for a specific project or software company is difficult. Every project has its requirements and might need its own development model. The most popular development models are trunk-based development and merge requests.<br/>There are no clear science-based guidelines on when to...

The participation of greenhouses in the redispatch market for congestion management on the electricity grid: Judging the redispatch market based on greenhouse grower specific characteristics

The growing share of renewable electricity generation poses a balancing challenge on the electricity grid and thus increases probability of for congestion on the electricity grid. On the supply side, flexibility can be built into the system. One option for a market to avoid congestion is the redispatch market, which is the way of solving...

Towards Understanding How Developers Comprehend Tests

Developers spend the majority of their time and effort on reading and comprehending source code. In order to improve this process of program comprehension for developers, a numerous amount of existing studies have looked into understanding how developers approach it and factors of influence. However, less is known in the field about how...

Improving Code Quality in Agile Software Development

Agile software development is a popular approach for developing software. Another important topic of research in software engineering is code quality. Unfortunately, a minimal amount of extensive research has been done on how these two influence each other. The goal of this study is therefore to explore the connection between these two using a...

Proposition and testing of a conceptual model describing the movement of individual pedestrians within a crowd

Our understanding of crowd movements has rapidly improved over the course of the last decades. This study shows that the empirical research has not kept up with the pace of the simulation studies. Based on an extensive literature review, this study proposes a conceptual model describing the movements of individuals within a crowd. The model...

The competition that changed your life: About and beyond winning

Are there recognizable patterns in the way competitions serve the development of architecture practices? How can competitions be effectively used by architects? The paper is based on a survey developed by the Wonderland platform for European architecture in collaboration with the Vienna based practice SHARE architects. 116 stories about ‘the...

Financing flood protection measures in developing countries: Are private investments feasible? Experience from Pevensey Bay Coastal Defence Project in UK

Are we on the same page? Comparing professional practices between industrial designers and mechanical engineers in perceptions and procedures during product development

The objective of this research is to find differences between industrial designers and mechanical engineers in perception and procedures during product development. This research has focused on cooperation between multidisciplinary teams’ participants - both industrial designers and mechanical engineers, because current innovation processes...
