Journal ArticleDOI
The Interplay of Adolescents’ Aggression and Victimization with Friendship and Antipathy Networks within an Educational Prosocial Intervention
Diego Palacios,Christian Berger,Bernadette Paula Luengo Kanacri,René Veenstra,Jan Kornelis Dijkstra +4 more
TL;DR: The findings suggest that the impact of an educational intervention may go beyond changing individual behavior and extend to the way peer relations develop in classrooms.
Journal ArticleDOI
What is popular? Distinguishing bullying and aggression as status correlates within specific peer normative contexts
Diego Palacios,Christian Berger +1 more
TL;DR: In this article, the authors tested social status correlates of aggression and bullying and how these are influenced by peer groups' normative beliefs about aggression and prosocial behavior among 1165 fourth, fifth and sixth graders in Chile.
Journal ArticleDOI
Monitoring Selective Logging in a Pine-Dominated Forest in Central Germany with Repeated Drone Flights Utilizing A Low Cost RTK Quadcopter
Christian Thiel,Marlin Müller,Christian Berger,Felix Cremer,Clémence Dubois,S. Hese,Jussi Baade,Friederike Klan,Carsten Pathe +8 more
TL;DR: This study focuses on selective logging at the level of individual trees using repeated drone flights using the new generation of UAS, which allows for sub-decimeter-level positioning accuracies, and a change detection approach based on bi-temporal UAS acquisitions was implemented.
Proceedings ArticleDOI
Sea-trial results for cyclic-prefix OFDM with long symbol duration
TL;DR: In this article, the authors report results from the Calibration and Communications Sea Trial 2010 and explain the used cyclic-prefix orthogonal frequency division multiplexing (OFDM) signal design and adopted receiver processing, based on sparse channel estimation and intercarrier interference equalization.
Proceedings ArticleDOI
Real-time software implementation of an IEEE 802.11a baseband receiver on Intel multicore
TL;DR: A software-only implementation of an IEEE 802.11a (WiFi) receiver optimized for Intel multicore platforms is presented, about 50 times faster than a straightforward C implementation, i.e., an implementation that has the same functionality, but leaves optimization completely to the compiler.
