    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Applied and experimental psychology; multidimensional scaling techniques; multiple sorting task; survey construction; conceptual systems; employee perceptions; underground offices; Work environment; Japan; Japan; Tillämpad och experimentell psykologi;

    Sammanfattning : The present doctoral dissertation discusses Japanese office employees' psychological reactions to their underground work environment. Studies I and III were methodological in nature and aimed at developing and validating instruments to be used in the empirical studies. LÄS MER

  4. 3. Channel-Aware Multilevel Coded Modulation for Coherent Fiber-Optic Communications

    Författare :Lotfollah Beygi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel model; multidimensional set partitioning; low-complexity de- tector; coded modulation; signal statistics.; nonlinear phase noise; Fiber-optic communications;

    Sammanfattning : The past decades have shown an ever-increasing demand for high-rate Internet services, motivating a great effort to increase the spectral efficiency of optical networks. In general, fiber-optic links are non-Gaussian, and in contrast to additive white Gaussian noise (AWGN) channels, there is no standard framework for quantifying fundamental limits or designing capacity-approaching coding schemes for such channels.

  5. 4. Forensic comparison of voices, speech and speakers : tools and methods in forensic phonetics

    Författare :Jonas Lindh; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; forensic phonetics; automatic voice recognition; disputed utterance; speech; language technology; phonetics;

    Sammanfattning : This thesis has three main objectives. The first objective (A) includes Study I, which investigates the parameter fundamental frequency (F0) and its robustness in different acoustic contexts by using different measures. LÄS MER
