  • Extractive gas analysis from a burning fixrd brd biofuel bed ---method and measurements

    • An experimental rig was built to investigate counter-current combustion under well defined conditions. Measurements were performed with extraxtive gas analysis from inside a burning fixed bed of biofuel. A number of species concentrations were measured, together with mass change and air flow. A gas suction probe was designed and a method was developed to achieve good accuracy and spatial resolution. The influence of primary air flow, fuel particle size and moisture content on ignition and combustion rate, the length of the devolatilisation and char combustion phases, the maximum tront temperature and concentrations leaving the bed was investigated.

  • Islet autoantibodies in the prediction of diabetes in school children
  • 2001
  • Ingår i: Diabetes Research and Clinical Practice. - 1872-8227 .- 0168-8227. ; 51:1, s. 51-57
  • Tidskriftsartikel (refereegranskat)abstract
    • In 1987 serum was collected from 1031 non-diabetic schoolchildren in the Southeast area of Sweden with the aim of evaluating islet autoantibody status (ICA, GADA and IA2-ab) in the prediction of diabetes in schoolchildren. The clinical development of Type 1 diabetes in the children was assessed in 1994 and 1997. The combination of ICA, GADA and IA2-ab were found in four subjects whereas six had two and 35 children one of these antibodies. After 10 years, six of the 1031 children had developed clinical diabetes and five of these six children were positive for islet antibodies. Two were positive for all three antibodies, two were positive for ICA and GADA, and one was positive for GADA. Among the individual autoantibodies, ICA showed the highest positive predictive value (29%) whereas the predictive value for the combination of two autoantibodies was highest for GADA and ICA (40%). Thus, GADA and ICA measurements may be a rational approach to detect schoolchildren at risk for developing diabetes.

  • Implementation of SM and RxTxIR on a DSP-Based Wireless MIMO Test-Bed
  • 2004
  • Ingår i: Proceedings of the European DSP Education and Research Symposium EDERS.
  • Konferensbidrag (refereegranskat)abstract
    • In this paper we describe the implementation of two smart-antenna strategies and associated signal processing algorithms on a common DSP-based wireless MIMO test-bed. The test-bed supports single cell and two-cell configurations. All nodes (MS andBS) have two antennas (either two transmit or tworeceive) and there are feedback links (via cable) from the receivers to all transmitters.These possibilities has been utilized differently in the two techniques: spatial multiplexing (SM) and joint receiver transmitter and interference rejection (RxTxIR).The SM technique targets a single-link low-mobility scenario and boosts throughput using two parallel spatially multiplexed modulation streams. The RxTxIR scheme utilizes the two-cell configuration of the testbed to demonstrate the possibility of suppressing intercell interference in transmitter as well as the receiver beamforming.
