  2. 1. High Strain Fatigue Crack Growth and Crack Closure

    Author : Michael Andersson; Materialteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; crack closure; high strain fatigue; crack grotwh;

    Abstract : Understanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. READ MORE

  4. 2. Characterisation and Modelling of Graphene FETs for Terahertz Mixers and Detectors

    Author : MICHAEL ANDERSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; graphene; millimetre and submillimetre waves; power detectors; nonlinear device modelling; microwave amplifiers; nanofabrication; integrated circuits; noise modelling; Field-effect transistors FETs ; terahertz detectors; Volterra; subharmonic resistive mixers;

    Abstract : Graphene is a two-dimensional sheet of carbon atoms with numerous envisaged applications owing to its exciting properties. In particular, ultrahigh-speed graphene field effect transistors (GFETs) are possible due to the unprecedented carrier velocities in ideal graphene. READ MORE

  5. 3. On testing and forecasting in fractionally integrated time series models

    Author : Michael K. Andersson; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This volume contains five essays in the field of time series econometrics. All five discuss properties of fractionally integrated processes and models. The first essay, entitled Do Long-Memory Models have Long Memory?, demonstrates that fractional integration can enhance the memory of ARMA processes enormously. READ MORE

  6. 4. Microwave characterisation of electrodes and field effect transistors based on graphene

    Author : MICHAEL ANDERSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; graphene electrodes; microwave amplifiers; noise measurements; microwave FETs; CVD graphene; noise modelling; FBARs.; nanofabrication; subharmonic resistive mixers; small-signal FET modelling;

    Abstract : The isolation of the two-dimensional material graphene, a single hexagonal sheet of carbon atoms, is believed to trigger a revolution in electronics. Theory predicts unprecedented carrier velocities in ideal graphene, from which ultrahigh speed graphene field effect transistors (GFETs) are envisioned. READ MORE

  7. 5. Muscarinic Receptors in the Urinary Bladder - The role of the urothelium regarding cholinergic and nitrergic effects in inflammation

    Author : Michael Andersson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; urinary bladder; inflammation; cyclophosphamide-induced cystitis; muscarinic receptor; urothelium; nitric oxide; M5 receptor; rat; proliferation; micturition;

    Abstract : Inflammation alters the functional properties of the urinary bladder. Interstitial cystitis (IC) is a chronic inflammatory syndrome in man that is characterized by urgency, frequency and visceral pain. READ MORE
