Potkamp, Storm (author)A Solar Electric Vehicle is a vehicle that receives a significant amount of its total energy consumption through sunlight gathered using solar arrays. The main objective of this thesis was to determine how the design of the rear low-speed crash structures should be different for a Solar Electric Vehicle, compared to conventional cars. This is...master thesis 2020

Soltani, M. (author), Panichella, A. (author), van Deursen, A. (author)Software systems fail. These failures are often reported to issue tracking systems, where they are prioritized and assigned to responsible developers to be investigated. When developers debug software, they need to reproduce the reported failure in order to verify whether their fix actually prevents the failure from happening again. Since...journal article 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Zaidman, A.E. (author), van Deursen, A. (author), Panichella, A. (author)Evolutionary-based crash reproduction techniques aid developers in their debugging practices by generating a test case that reproduces a crash given its stack trace. In these techniques, the search process is typically guided by a single search objective called Crash Distance. Previous studies have shown that current approaches could only...conference paper 2020

Soltani, M. (author), Derakhshanfar, P. (author), Devroey, Xavier (author), van Deursen, A. (author)Crash reproduction approaches help developers during debugging by generating a test case that reproduces a given crash. Several solutions have been proposed to automate this task. However, the proposed solutions have been evaluated on a limited number of projects, making comparison difficult. In this paper, we enhance this line of research by...journal article 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Perrouin, Gilles (author), Zaidman, A.E. (author), van Deursen, A. (author)Search-based crash reproduction approaches assist developers during debugging by generating a test case, which reproduces a crash given its stack trace. One of the fundamental steps of this approach is creating objects needed to trigger the crash. One way to overcome this limitation is seeding: using information about the application during the...journal article 2020

Borsos, Attila (author), Farah, H. (author), Laureshyn, Aliaksei (author), Hagenzieker, M.P. (author)In order to overcome the shortcomings of crash data a number of surrogate measures of safety have been developed and proposed by various researchers. One of the most widely used temporal indicators is time-to-collision (TTC) which requires the road users to be on a collision course. Road users that are strictly speaking not on a collision...journal article 2020

(author)Recent developments in the concept of UAS operations in urban areas have led to risk concerns of UAS collision with human. To better understand this risk, head and neck injuries due to UAS collisions have been investigated by different research teams using crash dummies. Because of the limitations in biofidelity of a crash dummy, head injury...journal article 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Zaidman, A.E. (author), van Deursen, A. (author), Panichella, A. (author)Writing a test case reproducing a reported software crash is a common practice to identify the root cause of an anomaly in the software under test. However, this task is usually labor-intensive and time-taking. Hence, evolutionary intelligence approaches have been successfully applied to assist developers during debugging by generating a test...conference paper 2020

These tests help developers during their debugging practices. One of the most promising techniques in this research field leverages search-based software testing techniques for generating crash reproducing test...conference paper 2020

Afghari, A.P. (author), Haque, Md Mazharul (author), Washington, Simon (author)Both crash count and severity are thought to quantify crash risk at defined transport network locations (e.g. intersections, a particulate section of highway, etc.). Crash count is a measure of the likelihood of occurring a potential harmful event, whereas crash severity is a measure of the societal impact and harm to the society. As the...journal article 2020

Kechagia, M. (author), Devroey, Xavier (author), Panichella, A. (author), Gousios, G. (author), van Deursen, A. (author)Application Programming Interfaces (APIs) typically come with (implicit) usage constraints. The violations of these constraints (API misuses) can lead to software crashes. Even though there are several tools that can detect API misuses, most of them suffer from a very high rate of false positives. We introduce Catcher, a novel API misuse...conference paper 2019

Ziakopoulos, Apostolos (author), Theofilatos, Athanasios (author), Papadimitriou, E. (author), Yannis, George (author)This study aims to estimate the overall impact of distraction due to operating in-vehicle information systems (IVIS) and similar devices while driving on road crashes. While similar research has been undertaken investigating the issue, varying results have been reported so far. Therefore a two-step approach was adopted: initially a review of...journal article 2019

van Lange, Dion (author)In this project we looked into financial markets. The goal of this project was to find out if a bubble is forming and when the most probable time of bursting would be. that is what we call the critical time. In order to do this we studied the work of Professor Didier Sornette, who is an expert in this field of mathematics. In this bachelor...bachelor thesis 2018

Pascarella, L. (author), Keshav Ram, A.R. (author), Nadeem, Azqa (author), Bisesser, Dinesh (author), Knyazev, Norman (author), Bacchelli, A. (author)Past research provided evidence that developers making code changes sometimes omit to update the related documentation, thus creating inconsistencies that may contribute to faults and crashes. In dynamically typed languages, such as Python, an inconsistency in the documentation may lead to a mismatch in type declarations only visible at runtime....conference paper 2018

Hoogendoorn, Tony (author)Cycling is one of the main transport modes in the Netherlands and the total number of bicycles and the total cycling distances are still rising. Although this seems a positive development, the number of seriously injured cyclists due to bicycle crashes without motor vehicles increased rapidly in recent years. Within these crashes the...master thesis 2017

Recent advances proposed the use of symbolic execution, mutation analysis, and directed model checking as underling techniques for post-failure analysis of crash stack traces. However, existing...conference paper 2017

Dekker, R. (author)Localized buckles can occur in crashes when compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to buckling will not be predicted. Methods to analytically assess the onset of such buckles are readily available. However, an off-the-shelf...master thesis 2016
