Residual signal auto-correlation to evaluate speech in Parkinson's disease patients.
OBJECTIVE To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients. METHOD The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender. RESULTS Statistical difference was seen between groups for PA, 0.39 for controls and 0.25 for PD. Normal valu...
متن کاملAuto-antibodies in Patients with Inflammatory Bowel Disease Unclassified
Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...
متن کاملAutomatic, unsupervised classification of dyskinesia in patients with Parkinsons Disease
One of the characteristic symptoms of patients with Parkinson Disease (PD) is a rigidity of movement. These symptoms disappear after administration of Levodopa. However, the long-term use of levodopa causes involuntary movements (dyskinesia). A proper diagnosis requires an automatic, unsupervised method for the detection and classification of levodopa induced dyskinesia. The main problem, howev...
متن کاملAdaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum
A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
متن کاملUsing a multi-criteria decision making approach (ANP-TOPSIS) to evaluate suppliers in Iran’s auto industry
Supplier selection is a multi-criteria problem which includes both tangible and intangible factors in these problems if suppliers have capacity or other different constraints two problems will exist: which suppliers are the best and how much should be purchased from each selected supplier? The objective of this paper is to present an integrated model and a supporting approach for effective ...
