2. 21. Achieving reliable networking for the generic autonomous platform for sensor systems : (GAP4S)

   Author : Paolo Monti; Andrea Fumagalli; Marco Tacca; The University Of Texas At Dallas; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Networks of wireless integrated sensors are often used to monitorparameters distributed in the environment. These parameters arerelated to a variety of applications such as security, patientmonitoring, chemical and biological hazard detection. Some solutionsrely on replaceable batteries with a limited life-time to providelong-term sensor operation. READ MORE

4. 22. A Neural Network Technique for Retrieving Atmospheric Species from Microwave Limb Sounders

   Author : Carlos Jimenez Sanchez; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Atmospheric radiometry requires solving an inversion problem due to the indirect nature of the measurements. Traditional iterative methods for non-linear inversions are computationally intensive and faster algorithms are desirable. READ MORE

5. 23. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

   Author : Rohit Chandra; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

   Abstract : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. READ MORE

6. 24. Superconducting kinetic inductance devices for nanoscale force sensing

   Author : August K. Roos; David B. Haviland; Hélène le Sueur; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optomechanics; force sensing; atomic force microscopy; kinetic inductance; superconductivity; strain; meandering nanowires; optomekanik; kraftavkänning; atomkraftsmikroskopi; kinetisk induktans; supraledning; töjning; slingrande nanotrådar; Material and Nano Physics; Material- och nanofysik;

   Abstract : In this thesis, we present a force sensor for atomic force microscopy based on cavity optomechanical principles. We explain the function, design, fabrication and characterisation of the force sensor. The mechanical part of the force sensor consists of a cantilever with a very fine tip. READ MORE

7. 25. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice

   Author : Mats I. Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAR; clutter suppression; space time adaptive processing; backprojection; remote sensing; moving target detection; radar scattering; Antenna array; wide band; sea ice;

   Abstract : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. READ MORE
