Software Engineers' Information Seeking Behavior in Change Impact Analysis - An Interview Study
Software engineers working in large projects must navigate complex
information landscapes. Change Impact Analysis (CIA) is a task that relies on
engineers' successful information seeking in databases storing, e.g., source
code, requirements, design descriptions, and test case specifications. Several
previous approaches to support information seeking are task-specific, thus
understanding engineers' seeking behavior in specific tasks is fundamental. We
present an industrial case study on how engineers seek information in CIA, with
a particular focus on traceability and development artifacts that are not
source code. We show that engineers have different information seeking
behavior, and that some do not consider traceability particularly useful when
conducting CIA. Furthermore, we observe a tendency for engineers to prefer less
rigid types of support rather than formal approaches, i.e., engineers value
support that allows flexibility in how to practically conduct CIA. Finally, due
to diverse information seeking behavior, we argue that future CIA support
should embrace individual preferences to identify change impact by empowering
several seeking alternatives, including searching, browsing, and tracing.Comment: Accepted for publication in the proceedings of the 25th International

Considerations about Continuous Experimentation for Resource-Constrained Platforms in Self-Driving Vehicles
Autonomous vehicles are slowly becoming reality thanks to the efforts of many
academic and industrial organizations. Due to the complexity of the software
powering these systems and the dynamicity of the development processes, an
architectural solution capable of supporting long-term evolution and
maintenance is required.
Continuous Experimentation (CE) is an already increasingly adopted practice
in software-intensive web-based software systems to steadily improve them over
time. CE allows organizations to steer the development efforts by basing
decisions on data collected about the system in its field of application.
Despite the advantages of Continuous Experimentation, this practice is only
rarely adopted in cyber-physical systems and in the automotive domain. Reasons
for this include the strict safety constraints and the computational
capabilities needed from the target systems.
In this work, a concept for using Continuous Experimentation for
resource-constrained platforms like a self-driving vehicle is outlined.Comment: Copyright 2017 Springer. Paper submitted and accepted at the 11th

Digital elevation modelling by radargrammetry in real-beam ground mapping mode
In this thesis the problem of estimating terrain elevation using two-dimensional radar data from the multirole ghter aircraft JAS 39 Gripen is considered. Radar data contains information about range from the aircraft to the reflecting terrain, as well as horizontal angle. In general, radar data has high resolution in range and low resolution in angle, giving rise to interesting problems. A new radar with higher resolution is in development for the next-generation Gripen. This thesis aims at answering whether estimation of terrain height can be done using available radar data, in order to evaluate the plausibility of doing this with data from the new radar. The approach is to find matching terrain features in subsequent images of the ground, and use this information to calculate terrain elevation. Two approaches are implemented and studied, both on simulated radar data and on real datasets. One approach uses Harris corner detection and the other uses Speeded-Up Robust Features (SURF). Conclusions drawn are that the algorithms do not work for the available radar data, but that they possibly could work when higher resolution data from the new radar is available
