1. 6. Distributed Control of Electric Drive Systems via Ethernet

   Författare :Lilantha Samaranayake; Chandur Sadarangani; Alexander Medvedev; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive sampling scheme; control delay; delay compensation; distributed control systems; Ethernet; Ethernet ready sensor actuator module; sampling period; Electrical engineering; Elektroteknik;

   Sammanfattning : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. LÄS MER

3. 7. Data-driven Train Delay Prediction

   Författare :Kah Yong Tiong; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Predictive models; Data-driven; Railways; Train Delays;

   Sammanfattning : In Sweden, extensive use and the inherent heterogeneity of train traffic have significantly increased the sensitivity of the train system so that the delay of one train can easily propagate to others. Repeated experiences with train delays can lead passengers to perceive that railway transportation is unreliable. LÄS MER

4. 8. Breast cancer in rural India : knowledge, attitudes, practices; delays to care and quality of life

   Författare :Nitin Gangane; Miguel San Sebastian; Nawi Ng; Anna-Karin Hurtig; Peter Vedsted; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; rural; India; knowledge; attitudes; practices; delay; quality; folkhälsa; Public health; Epidemiology; epidemiologi;

   Sammanfattning : Background: Cancer is a major public health problem globally. The incidence of cancer is increasing rapidly in many low- and middle-income countries like India due to the epidemiological transition. At present, breast cancer is the leading cancer in females in many countries including India. LÄS MER

5. 9. Penile carcinoma : from first symptom to sexual function and life satisfaction following organ-sparing laser treatment

   Författare :Elisabet [Elisabeth] Skeppner; Jan-Erik Johansson; Torgny Windahl; Kerstin Sjögren Fugl-Meyer; Hans Hedelin; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Penile carcinoma; sexuality; life satisfaction; treatment-seeking; sexual function; Sexual dysfunction; delay; organ-sparing; Surgery; Kirurgi;

   Sammanfattning : The overall aim of this thesis was to describe how patients with penile carcinoma experienced their symptoms, treatment seeking and the impact of the diagnosis and treatment on sexual function, sexual activity and life satisfaction. The thesis contains two studies of patients treated with organ-sparing laser therapy, a retrospective study (Papers II and III) of 46 patients treated between 1986-2000 and a prospective study (Papers I and IV) of 50 patients between 2005 and 2009 and additional 34 partners.

7. 10. Input-Output Stability Analysis of Networked Control Systems

   Författare :Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). LÄS MER
