2. 21. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

   Author : Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

   Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

4. 22. Circuit-level analyses of cortico-basal ganglia-thalamic networks. Effects of dopamine dysregulation and experience dependent plasticity

   Author : Nedjeljka Ivica; Integrativ neurofysiologi; []
   Keywords : systems neurophysiology; multi-channel recording; motor control; Parkinson s disease; oscillations; dyskinesia; plasticity;

   Abstract : The cortico-basal ganglia-thalamic (CBT) circuit is thought to be involved in control of voluntary and goal-directed movements and action selection. Dopamine is known to play a crucial role in this circuit and regulating its activity. READ MORE

5. 23. Relay Feedback and Multivariable Control

   Author : Karl Henrik Johansson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

6. 24. Correlations of Higher Order in Networks of Spiking Neurons

   Author : Stojan Jovanovic; Stefan Rotter; John Hertz; Jeanette Hällgren Kotaleski; Jean-Philippe Bouchard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuronal network; oscillations; correlations; Computer Science; Datalogi;

   Abstract : The topic of this dissertation is the study of the emergence of higher-order correlations in recurrentlyconnected populations of brain cells.Neurons have been experimentally shown to form vast networks in the brain. READ MORE

7. 25. Regulation of spontaneous tone in guinea pig trachea

   Author : Staffan Skogvall; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tetrodotoxin; lidocaine; substance P; tachykinin; prostaglandin; indomethacin; capsaicin; neuroepithelial endocrine cells; epithelium; oxygen; oscillations; spontaneous tone; Asthma; airway smooth muscle; electrical field stimulation.; Physiology; Fysiologi;

   Abstract : Asthma is a common disease, characterized by periods of bronchoconstriction of unclear origin. This thesis examines a specific behavior of airway smooth muscle, the so-called spontaneous airway tone. It was suspected that a defect regulation of this tone may be a cause of asthmatic bronchoconstriction. READ MORE
