  1. 1. Rapid Facial Reactions to Emotionally Relevant Stimuli

    Författare :Monika Thunberg; Ulf Dimberg; Mats Fredrikson; Georg Stenberg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Emotion; facial EMG; facial reactions; facial expressions; rapid responses; automatic responses; phobia; social fear; speech anxiety; Psychology; Psykologi;

    Sammanfattning : The present thesis investigated the relationship between rapid facial muscle reactions and emotionally relevant stimuli. In Study I, it was demonstrated that angry faces elicit increased Corrugator supercilii activity, whereas happy faces elicit increased Zygomaticus major activity, as early as within the first second after stimulus onset.

  3. 2. New Instrumentation for Forensic Applications : Automatic Fiber Detection and Breath Alcohol Measurements

    Författare :Nils Paulsson; Peter Wide; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Two forensic instruments have been developed and evaluated with respect to basic characteristics. One instrument is used for automatic fiber detection and the other for breath alcohol measurement. LÄS MER

  4. 3. Estimation and Control of Resonant Systems with Stochastic Disturbances

    Författare :Peter Nauclér; Torsten Söderström; Anders Robertsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; Automatic control; Reglerteknik;

    Sammanfattning : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. LÄS MER

  5. 4. Automatic speaker verification on site and by telephone: methods, applications and assessment

    Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; Information and language technology; Informations- och språkteknologi;

    Sammanfattning : Speaker verification is the biometric task of authenticating a claimed identity by means of analyzing a spoken sample of the claimant's voice. The present thesis deals with various topics related to automatic speaker verification (ASV) in the context of its commercial applications, characterized by co-operative users, user-friendly interfaces, and requirements for small amounts of enrollment and test data.

  7. 5. Between Ourselves : Automatic mimicry reactions as related to empathic ability and patterns of attachment

    Författare :Marianne Sonnby-Borgström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neurophysiology; neuropsychology; Neurology; emotion regulation; attachment pattern; empathy; EMG; Key words:Facial mimicry; emotional contagion; Differential and individual psychology; Neurologi; neuropsykologi; neurofysiologi; Differentiell och individuell psykologi;

    Sammanfattning : This thesis investigated emotional communication in experimentally created face-to-face interaction situations. The hypotheses were based on the conception of a process which leads to emotional empathy, assuming that automatic mimicking tendencies are involved in an automatic part of the process. LÄS MER
