Reducing the radar cross-section of microstrip arrays using AMC structures for the vehicle integration of automotive radars
(Universität Ulm, 2018)
Automotive radar sensors for driver assistance systems are usually installed behind the bumper of the car. Multiple reflections between radar and bumper can occur and may lead to a wrong estimation of the direction of ...
High range and doppler resolution by application of compressed sensing using low baseband bandwidth OFDM radar
(Universität Ulm, 2018-06-05)
Multi-carrier waveforms such as orthogonal frequency-division multiplexing (OFDM) found their way into radar applications in the last few years. However, currently, typically only a fraction of the large baseband bandwidth ...
Dielectric properties of graphene/MoS2 heterostructures from ab initio calculations and electron energy-loss experiments
(Universität Ulm, 2018-06-07)
High-energy electronic excitations of graphene and MoS2 heterostructures are investigated by momentum-resolved electron energy-loss spectroscopy in the range of 1 to 35 eV. The interplay of excitations on different sheets ...
Mindfully green and healthy: An indirect path from mindfulness to ecological behavior
(Universität Ulm, 2018-01-18)
This paper examines the nature of the link between mindfulness and ecological behavior. Based on the notion that mindfulness incorporates heightened awareness of bodily sensations, we suggest an indirect path from mindfulness ...
Why don’t you go to bed on time? A daily diary study on the relationships between chronotype, self-control resources and the phenomenon of bedtime procrastination
(Universität Ulm, 2018-02-02)
Background: This daily diary study investigates the phenomenon of bedtime procrastination. Bedtime procrastination is defined as going to bed later than intended, without having external reasons for doing so. We highlight ...
Knowledge is power for medical assistants: crystallized and fluid intelligence as predictors of vocational knowledge
(Universität Ulm, 2018-02-01)
Medical education research has focused almost entirely on the education of future physicians. In comparison, findings on other health-related occupations, such as medical assistants, are scarce. With the current study, we ...
Radar taking off: New capabilities for UAVs
(Universität Ulm, 2018-10-12)
Modern consumer and industrial unmanned aerial vehicles (UAVs) are easy-to-use flying sensor platforms. They offer stable flight, good maneuverability, hovering, and even waypoint flights in autopilot mode. For stabilization ...
Facial responsiveness of psychopaths to the emotional expressions of others
(Universität Ulm, 2018-01-11)
Psychopathic individuals show selfish, manipulative, and antisocial behavior in addition to emotional detachment and reduced empathy. Their empathic deficits are thought to be associated with a reduced responsiveness to ...
Survey of protocol reverse engineering algorithms: Decomposition of tools for static traffic analysis
(Universität Ulm, 2018)
Knowledge about a network protocol to understand the communication between entities is necessary for vulnerability research, penetration testing, malware analysis, network reconnaissance, and network modeling. Traffic ...
A generalized model for two-element biomimetic antenna arrays
(Universität Ulm, 2018-12-19)
Biomimetic Antenna Arrays (BMAAs) are antenna systems enabling an improved angle estimation for small apertures by mimicking the hearing system of the fly Ormia ochracea. This is achieved by a special kind of coupling ...
