1. 36. Clinical studies of biomarkers in suicide prediction

   Författare :Jussi Jokinen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Suicide; suicide attempt; HPA axis; dexamethasone suppression test DST ; serum cortisol; Receiver Operating Characteristic ROC ; serotonin; CSF 5-HIAA; depression; prediction; suicide intent; hopelessness;

   Sammanfattning : Suicide is a major clinical problem in psychiatry and suicidal behaviours can be seen as a nosological entity per se. Predicting suicide is difficult due to its low base-rate and the limited specificity of clinical predictors. LÄS MER

3. 37. The meaning of gender in management : Investigating factors influencing women's and men's entry into management from social-psychological perspective

   Författare :Sophia Marongiu Ivarsson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Women managers; person-manager fit; gender; managerial advancement; Psykologi; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : This thesis presents four studies examining some common explanations to the gender gap in managerial positions. Study I compared managerial aspirants with non-managerial aspirants and showed that regardless of sex, the major predictor of managerial aspirations was an internal factor consisting of instrumental ("masculine")qualities.

4. 38. Trypsinogen and Its Activation in Acute Pancreatitis

   Författare :Ulf Petersson; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TAP; ERCP; carboxypeptidase B activation peptide; trypsinogen activation peptide; trypsinogen activation; Acute pancreatitis; trypsinogen; CAPAP; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Pancreatic enzymes, neutrophils, free radicals and cytokines are involved in the pathophysiology of AP. Clarification of their interaction and time-course will improve our understanding of AP and provide a better basis for treatment. LÄS MER

5. 39. Gradient Methods for Large-Scale and Distributed Linear Quadratic Control

   Författare :Karl Mårtensson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large-Scale Control; Distributed Control; Linear Quadratic Gaussian Control; Gradient method; Controller Synthesis;

   Sammanfattning : This thesis considers methods for synthesis of linear quadratic controllers for large-scale, interconnected systems. Conventional methods that solve the linear quadratic control problem are only applicable to systems with moderate size, due to the rapid increase in both computational time and memory requirements as the system size increases.

7. 40. Radio Channel Prediction Based on Parametric Modeling

   Författare :Ming Chen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; channel prediction; GLRT; CRLB; NLLS; polynomial phase signal; Kalman filter; NILS.; sinusoidal modeling; channel modeling; MIMO;

   Sammanfattning : Long range channel prediction is a crucial technology for future wireless communications. The prediction of Rayleigh fading channels is studied in the frame of parametric modeling in this thesis.Suggested by the Jakes model for Rayleigh fading channels,deterministic sinusoidal models were adopted for long rangechannel prediction in early works.
