2. 1. Resistance breathing with PEP and CPAP : effects on respiratory parameters

   Author : Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

   Abstract : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. READ MORE

4. 2. Vertical InAs Nanowire Devices and RF Circuits

   Author : Martin Berg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOSFET; Metal-oxide-semiconductor field-effect transistor; Transistor; Vertical; InAs; III-V semiconductor; Nanowire; Fabrication; DC; Resistor; TLM; RF; Mixer; Circuit.;

   Abstract : Recent decades have seen an exponential increase in the functionality of electronic circuits, allowing for continuous innovation, which benefits society. This increase in functionality has been facilitated by scaling down the dimensions of the most important electronic component in modern electronics: the Si-based MOSFET. READ MORE

5. 3. Modeling and constructing unstructured overlay networks: Algorithms, techniques and the Smart Grid case

   Author : Georgios Georgiadis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; matching; smart grid; online computation; scheduling; unstructured overlays; random walks; natural computing; resistor networks; clustering;

   Abstract : Throughout its lifetime, the Internet was always associated with overlay networks; from the WorldWideWeb and peer-to-peer networks to blogs and social networking solutions, overlays built on the Internet infrastructure gave it additional value and made it more engaging to everyday users. Today, rising overlay networks such as the Smart Grid as well as a multitude of sensor, mobile andwireless networks herald a new era of unprecedented connectivity and networking. READ MORE

6. 4. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications

   Author : Disala Uduwawala; KTH; []
   Keywords : Ground penetrating radar; Buried object detection; Simulation; Radar antennas; Radar signal processing; FDTD methods; Optimal design; Lossy media; Dispersive media; Clutter; Polarization;

   Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE
