Comparative testing of radar signal representations when sensing through materials
Nuwan Attygalle, Matjaž Kljun, Una Vuletić, Klen Čopič Pucihar, 2026, independent scientific component part or a chapter in a monograph

Abstract: The ability to sense mid-air gestures with miniaturised radars embedded in everyday objects opens up new opportunities for interaction. Applications include integration into wearable devices, automotive dashboards, smart furniture, and other components within smart environments. Despite this potential, the lack of studies on how various occluding materials affect gesture recognition performance hinders progress in this area. Previous studies have primarily focused on evaluating only one type of radar signal representation, despite the fact that several other representations exist and were proved effective. To address this, the chapter presents a comparative evaluation of four radar signal representations: In-phase and Quadrature (IQ) representations in the frequency domain and magnitude and range-angle (including both elevation and azimuth components) and range-Doppler. The goal is to assess their robustness against signal distortions introduced by occluding materials. Preliminary results indicate that recognition performance tends to improve with a higher transmission coefficient. Moreover, range-Doppler and range-angle representations exhibit significantly greater robustness to distortion compared to IQ representations

Collective memory and social identity : a social psychological exploration of the memories of the disintegration of former Yugoslavia
Marja Kuzmanić, 2008, original scientific article

Abstract: Through narration of memories of events related to the disintegration of Yugoslavia, this study takes a social psychological approach and explores the generational and ethnic group differences in collective memories, social representations and social identities of peoples living in Slovenia. It represents an initial step at mapping out the differing collective memories, representations and identities of Slovenians and other former Yugoslav peoples now resident in Slovenia in relation to some of the major recent historical and political events (Tito's death, the wars in Slovenia, Bosnia and Croatia, the beginning of the war(s), and the attainment of independence of Slovenia). Eighteen semi-structured interviews with members of three ethnic communities (Bosniac and Serb minority and Slovenian majority) were conducted and are qualitatively analysed. The findings are discussed in two sections. The first illustrates the contested interpretations of the break up of the federation, whereas the second section discusses the complex changes inidentification that occurred during the transition in the Slovenian context. Above all, the material reveals that contested narratives of the breakup of Yugoslavia (the narratives of 'transition', 'disintegration' and 'war') are present.
