2. 1. Input-Output Stability Analysis of Networked Control Systems

   Author : Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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). READ MORE

4. 2. Young adults in urban Pakistan : barriers and challenges for improving health behaviors in the wake of the HIV/AIDS epidemic

   Author : Syed Farid-ul Hasnain; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Young adults; dropouts; knowledge and awareness; HIV AIDS; STDs; family planning; gender roles; life prospects; Karachi;

   Abstract : Background: HIV/AIDS is spreading globally more specifically among the younger generation. The impact of HIV/AIDS on the youth cannot be underestimated. According to the UNAIDS report 2008; an estimated number of 33 million people around the globe were living with HIV in 2007, and overall, 2. READ MORE

5. 3. Measuring eating disorder outcome : definitions, dropout and patients' perspectives

   Author : Tabita Björk; Claes Norring; David Clinton; Gerd Ahlström; Bruno Hägglöf; Örebro universitet; []
   Keywords : MEDICINE; MEDICIN; Medicine; Medicin;

   Abstract : Background: Despite a plethora of research, there are serious limitations in our knowledge of outcome in eating disorders. Almost all studies have been compromised by the problem of treatment dropout or non-participation in follow-ups. READ MORE

6. 4. Harvesting Based Communications for Wireless Control Systems : Event-Trigger and Reinforcement Learning Based Transmission Policies

   Author : Ruslan Seifullaev; Steffi Knorn; Anders Ahlén; Fredrik Gustafsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless control systems; energy harvesting; event-triggered control; Lyapunov stability analysis; fading channel; quantized data; Markov models; Bayesian estimation; reinforcement learning; dynamic programming; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Abstract : Wireless control systems have gained considerable attention in recent years due to their numerous advantages, including increased flexibility and scalability, reduced wiring complexity, and cost-efficiency. Despite these benefits, the use of communication networks in control loops poses various challenges, such as sampled data, latency, packet dropouts, etc. READ MORE

7. 5. Computer-based support for maternal and child care at primary health centres

   Author : Khalid Moidu; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Health infonnation systems are reported to be weak and inadequate in supporting public health programs, since at the primary health centre, which is the level of first contact, the information infrastructure is weak. This thesis reports a health systems research effort to strengthen the infonnation infrastructure, specifically to develop an application software to support the delivery of maternal and child care at the primary health centre.
