Yayın On the extraction of the channel allocation information in spectrum pooling systems(IEEE, 2007-04) Öner, Mustafa Mengüç; Jondral, Friedrich K.The spectrum pooling strategy allows a license owner to share a part of his licensed spectrum with a secondary wireless system (the rental system, RS) during its idle times. The coexistence of two mobile systems on the same frequency band poses many new challenges, one of which is the reliable extraction of the channel allocation information (CAI), i.e. the channel occupation of the licensed system (LS). This paper presents a strategy for the extraction of the CAI based on exploiting the distinct cyclostationary characteristics of the LS and RS signals and demonstrates, via simulations, its application on a specific spectrum pooling scenario, where the LS is a GSM network and the RS is an OFDM based WLAN system.Yayın Microwave engineering expertise in Turkey(Institute of Electrical and Electronics Engineers Inc., 2018-05) Yarman, Bekir Sıddık Binboğa; Palamutçuoğulları, Osman; Kaya, İlker; Kızılbey, Oǧuzhan; Aksen, Ahmet; Akın, Tayfun; Özkan, Z.

It aims to re-conceptualise “child’s participation” through exploring its relationship with POE by observing child-built environment connection and by demonstrating how children engage with the problems of school design. This empirically grounded research presents eight workshops with three different schools in Albania. It explores the process, outcomes, challenges, and opportunities during the active involvement of a total of 502 children aged 10–14 years old. The research incorporates a multiplicity of techniques from both creative and evaluative methods: essays, wish poem, drawing, model making, poster design, visual/POE questionnaire and walk-through are some that ensure a comprehensive achievement of children in the process. The study confirms the utility of participation in school design as a tool to propose child-oriented spaces. Within the results, six design concepts of the desired school building of children are identified. These are flexibility, horizontality, campus-like environment, transparency, accessibility, and ecological concept. We propose a participation language based on the experience, perception, imagination, and active involvement of the children in the learning environments. It concludes that children participation builds upon a spatial experience which lies on the child-school relationship. Language is dynamic and allows researchers and designer to edit and annotate whenever needed, but by always referring to the school of children active and present in participation. It emphasises the POE-participation connection and to further open the discourse of participation to the Albanian public.
