The relationship between the degree of overlap in direct modulation chirp spread spectrum systems with binary phase shift keying and intersymbol interference (ISI) is analyzed. It is observed that the ISI due to overlap fluctuates or monotonically increases as the number of overlaps changes and that, in some cases, the overlap does not incur ISI at all. key words: CSS, DM, BER, chirp, overlap
We propose a new metric and data source to assess journal impact in the field of Economics & Business. The metric – Hirsch’s h-index – improves on the traditionally used ISI Journal Impact Factor by providing a more robust and less time-sensitive measure of journal impact. The data source – Google Scholar – provides a more comprehensive coverage of citations than ISI, including citations in boo...
AIMS To assess the construct validity of the incontinence severity index (ISI) by testing its correlation with two health-related quality of life measures, the short forms of the Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7), in women with urodynamic stress incontinence. MATERIALS AND METHODS A cohort of 170 women with the urodynamic stress incontinen...
The purpose of this study was to investigate whether pre- to postoperative changes of increased signal intensity (ISI) of the spinal cord as seen on T2-weighted magnetic resonance imaging (MRI) reflect the surgical outcome in patients with cervical spinal cord injury without radiologic evidence of trauma (SCIWORET). In this study, 54 patients with SCIWORET who underwent expansive laminoplasty w...
