    Nyckelord :Technology; aluminum nitride; FBAR; shear mode resonator; lamb wave devices; liquid sensor; biosensor; temperature compensation; reactive sputtering; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The explosive development of the telecom industry and in particular wireless and mobile communications in recent years has lead to a rapid development of new component and fabrication technologies to continually satisfy the mutually exclusive requirements for better performance and miniaturization on the one hand and low cost on the other. A fundamental element in radio communications is time and frequency control, which in turn is achieved by high performance electro-acoustic components made on piezoelectric single crystalline substrates.

    Sammanfattning : The thesis analyses the continuously changing discourse of cultural diversity. The focus of this study is the ways in which this discourse is shaped within contemporary Swedish cultural politics in general, and how it unfolds and further changes through the specific activities performed by a cultural institution in Stockholm – Södra teatern.
