An Array Decomposition Method for Finite Arrays with Electrically Connected Elements for fast Toeplitz Solvers
Lucas Åkerstedt, Harald Hultin, B. L. G. Jonsson
A large part of the geometry of array antennas is often partially defined by finite translational symmetries. Applying the method of moments (MoM) with the RWG-like element on an a…
Experimental Evaluation of Moving Target Compensation in High Time-Bandwidth Noise Radar
Martin Ankel, Robert S. Jonsson, Mats Tholen +3
In this article, the effect a moving target has on the signal-to-interference-plus-noise-ratio (SINR) for high time-bandwidth noise radars is investigated. To compensate for cell m…
Optimizing Variational Quantum Algorithms with qBang: Efficiently Interweaving Metric and Momentum to Navigate Flat Energy Landscapes
David Fitzek, Robert S. Jonsson, Werner Dobrautz +1
Variational quantum algorithms (VQAs) represent a promising approach to utilizing current quantum computing infrastructures. VQAs are based on a parameterized quantum circuit optim…
Finding Minimum-Cost Explanations for Predictions made by Tree Ensembles
John Törnblom, Emil Karlsson, Simin Nadjm-Tehrani
The ability to explain why a machine learning model arrives at a particular prediction is crucial when used as decision support by human operators of critical systems. The provided…
Agility is responsiveness to change: An essential definition
Lucas Gren, Per Lenberg
There is some ambiguity of what agile means in both research and practice. Authors have suggested a diversity of different definitions, through which it is difficult to interpret w…
What software engineering can learn from research on affect in social psychology
Lucas Gren, Per Lenberg, Karolina Ljungberg
Social psychology researchers have, traditionally, focused on the construct of thinking rather than on feeling. Since the beginning of the 21st century, social science researchers…
