But despite their great importance, they are still carried out in a way that relies on human skills and decisions. During the last decade, there have been several publications on code reviews using eye tracking as a method, but only a few studies have focused on the performance differences between experts and novices. To get a deeper understanding of these differences, the following experiment was developed: This study surveys expertise-related differences in experts', advanced programmers', and novices' eye movements during the review of eight short C++ code examples, including correct and erroneous codes. A sample of 35 participants (21 novices, 14 advanced and expert programmers) were recruited. A Tobii Spectrum 600 was used for the data collection. Measures included participants' eye movements during the code review, demographic background data, and cued retrospective verbal comments on replays of their own eye movement recordings. Preliminary results give proof for experience-related differences between participants. Advanced and expert programmers performed significantly better in case of error detection and the eye tracking data implies a more efficient reviewing strategy.}, language = {en} } @inproceedings{HauserStarkMottoketal., author = {Hauser, Florian and Stark, Theresa and Mottok, J{\"u}rgen and Gruber, Hans and Reuter, Rebecca}, title = {Deliberate Practice in Programming: How is it carried out by programmers?}, series = {ECSEE '20: Proceedings of the 4th European Conference on Software Engineering Education, Seeon, Germany, June 2020}, booktitle = {ECSEE '20: Proceedings of the 4th European Conference on Software Engineering Education, Seeon, Germany, June 2020}, isbn = {ISBN 9781450377522}, doi = {10.1145/3396802.3396815}, pages = {42 -- 46}, abstract = {This work in progress study examines through which activities programmers perform deliberate practice to improve their own skills in coding and programming. For this reason, a qualitative questionnaire was developed and conducted with a sample of 22 participants. The results indicate that programmers perform formal and informal forms of training and learning. Typically, a classical programming training in the context of a university course or for work-related reasons is a first step in the acquisition of expertise. Building on these basic skills, non-formal and informal learning activities are carried out by the learners. Especially the social interaction and the collaborative work with other programmers is of great importance in this context. The activities mentioned by the test persons fulfil the characteristics of deliberate practice and will be examined more closely in a further study.}, language = {en} } @article{DeNiklasBrianetal., author = {De, Sangita and Niklas, Michael and Brian, Rooney and Mottok, J{\"u}rgen and Brada, Premek}, title = {Semantic Mapping of Component Framework Interface Ontologies for Interoperability of Vehicle Applications}, series = {Procedia Computer Science}, volume = {170}, journal = {Procedia Computer Science}, number = {2}, publisher = {Elsevier}, doi = {10.1016/j.procs.2020.03.151}, pages = {813 -- 818}, abstract = {Over the past few years, ontology merging, and ontology semantic alignment has gained significant interest as research topics in automotive application domain for finding solutions to semantic data heterogeneity. To accomplish the complex and novel vehicle service requirements such as autonomous driving, V2X (Vehicle-to-Vehicle communication), etc. the automotive applications involve collaborations of several platform-specific data from heterogeneous enterprises component frameworks and consequently there has been increase in data interoperability issues. At the application component level, data interoperability relies on the semantic alignment or mapping between the various component framework interfaces data models represented as XML schemas (XSD). With the XML schemas being the preferred standard for the interface description exchange between most of the automotive application domain components, however, the data interoperability between the semantically equivalent but structurally different data constructs of multiple heterogeneous XSDs stands as a challenge in the absence of an ontology-based approach. To confront this crucial requirement for data interoperability and to increase in effect the reuse of existing components through their interfaces, we propose an approach to semantically map the various component framework interface data models when expressed as ontology schemas, based on the exploration of semantic synergies. The transformation between XSD and RDF (Resource Description Framework) schema representations and the use of queries over the ontology schemas for semantic mapping are demonstrated including a real-world case study.}, language = {en} } @techreport{TaiberChowduryHammondetal., author = {Taiber, Joachim and Chowdury, M. and Hammond, G. and Hipp, V. and Huttner, B. and Lonien, J. and Mottok, J{\"u}rgen and Neukart, Florian and Stengel, T.}, title = {Unsettled Topics Concerning the Impact of Quantum Technologies on Automotive Cybersecurity}, address = {Warrendale, Pennsylvania, USA}, issn = {2640-3536}, doi = {10.4271/EPR2020026}, abstract = {Quantum computing is considered the "next big thing" when it comes to solving computational problems impossible to tackle using conventional computers. However, a major concern is that quantum computers could be used to crack current cryptographic schemes designed to withstand traditional cyberattacks. This threat also impacts future automated vehicles as they become embedded in a vehicle-to-everything (V2X) ecosystem. In this scenario, encrypted data is transmitted between a complex network of cloud-based data servers, vehicle-based data servers, and vehicle sensors and controllers. While the vehicle hardware ages, the software enabling V2X interactions will be updated multiple times. It is essential to make the V2X ecosystem quantum-safe through use of "post-quantum cryptography" as well other applicable quantum technologies. This SAE EDGE™ Research Report considers the following three areas to be unsettled questions in the V2X ecosystem: How soon will quantum computing pose a threat to connected and automated vehicle technologies? What steps and measures are needed to make a V2X ecosystem "quantum-safe?" What standardization is needed to ensure that quantum technologies do not pose an unacceptable risk from an automotive cybersecurity perspective?}, language = {en} }
