  1. 1. Evaluating the performance of TEWA systems

    Author : Fredrik Johansson; Göran Falkman; Lars Karlsson; Lars Niklasson; Martin Holmberg; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; air defense; information fusion; performance evaluation; threat evaluation; TEWA; weapon allocation; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap; Teknik; Technology;

    Abstract : It is in military engagements the task of the air defense to protect valuable assets such as air bases from being destroyed by hostile aircrafts and missiles. In order to fulfill this mission, the defenders are equipped with sensors and firing units. To infer whether a target is hostile and threatening or not is far from a trivial task. READ MORE

  2. 2. Process chain simulation of forming, welding and heat treatment of Alloy 718

    Author : Joachim Steffenburg-Nordenström; Lars-Erik Svensson; Lars-Erik Lindgren; Fredrik Niklasson; Högskolan Väst; []

    Abstract : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. READ MORE

  3. 3. Optical Absorption and Electrical Conductivity in Lithium Intercalated Amorphous Tungsten Oxide Films

    Author : Lars Berggren; Gunnar A. Niklasson; Ola Hunderi; Uppsala universitet; []
    Keywords : Technology; Lithium intercalation; amorphous; tungsten-oxide; sputtered films; optical absorption; polaron radius.; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Optical and electrical properties of electrochemically lithium ion intercalated thin films of x-ray amorphous tungsten oxide made by magnetron sputtering on glass substrates coated with a thin layer of conductive tin doped indium oxide, have been studied. The composition and the density of the films were characterized by the ion beam analysis methods Rutherford Backscattering Spectroscopy and Elastic Recoil Detection Analysis. READ MORE

  4. 4. Anomaly detection in the surveillance domain

    Author : Christoffer Brax; Lars Niklasson; Göran Falkman; Dimiter Driankov; Henric Johnson; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Anomaly Detection; Information Fusion; Visual Surveillance; Maritime Domain Awareness; Computer and Systems Science; Data- och systemvetenskap; Teknik; Technology;

    Abstract : In the post September 11 era, the demand for security has increased in virtually all parts of the society. The need for increased security originates from the emergence of new threats which differ from the traditional ones in such a way that they cannot be easily defined and are sometimes unknown or hidden in the “noise” of daily life.
