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

   Author : Anders Hansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE
