  5. 4. Generalized APP Detection for Communication over Unknown Time-Dispersive Waveform Channels

    Författare :Anders Hansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The principle of transmitting time-equidistant pulses to carry discrete information is fundamental. When the pulses overlap, intersymbol interference occurs. Maximum-likelihood sequence detection of such signals observed in additive white Gaussian noise (AWGN) was known in the early 1970s. LÄS MER

  7. 5. CSF biomarkers in idiopathic normal pressure hydrocephalus- Diagnostics and pathophysiology

    Författare :Anna Jeppsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; idiopathic normal pressure hydrocephalus; cerebrospinal fluid; biomarkers;

    Sammanfattning : Idiopathic normal pressure hydrocephalus (iNPH) is a disease of the elderly with enlarged ventricles despite a normal CSF pressure. Clinically, iNPH presents with gait- and balance disturbances, cognitive decline and incontinence. As the symptoms are reversed by shunt surgery, precise diagnostics is of essence. LÄS MER
