The concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase...

This paper presents a common gestural interface to mobile and pervasive computing devices. We report our development of a novel technique for recognizing input strokes on a range of mobile and pervasive devices, ranging from small devices with low processing capabilities and limited input area to computers with wall-sized displays and an input area as large as can be accommodated by motion-sens...

Stromal disease (ectasia, opacities, scars, or melting) that occurs after penetrating keratoplasty (PK) can variously affect visual outcome.1,2 To date, even in the presence of healthy endothelium, this typeof complicationhasbeen treatedwith subsequentPK.3 Instead, the selective replacement of the diseased stroma by means of deep anterior lamellar keratoplasty (DALK) using pneumatic dissection ...

OBJECTIVE The authors report their experience with a new prosthetic technique for the repair of incisional hernia defects smaller than 3 cm. METHODS From January 1995 to September 2002, 16 operations for small incisional hernias have been performed. Local anaesthesia was used in 12 out of 16 patients (75%). The repair was achieved by insertion of a polypropylene plug sutured to the margins of...

The aim of the present study was to perform an immunohistological assessment of the synovial tissue from involved small joints in rheumatoid arthritis (RA) and to explore the reliability of a mini-invasive ultrasound (US)-guided technique of small joint synovial biopsy for the histopathological assessment. Synovial tissue collected during arthrotomic surgery of small joints in nine patients ser...
