BACKGROUND Pulse wave velocity (PWV) is correlated with cardiovascular risk. This study presents a new method for measuring the arterial PWV by simultaneously recording the digital volume pulse through the finger and the toe by way of dual-channel photoplethysmography (PPG). METHODS In this study, 100 asymptomatic subjects (54 men and 46 women, 19 to 64 years of age) were enrolled. The PWV wa...

In this paper we present a new approach towards assistance and awareness systems that exploits the duality of automated homes; the status of devices and appliances in the real world on the one hand, and their digital representation on the other hand. If the digital representation is embedded in a virtual world, i.e., a 3-D model that reflects the actual physical environment, we call this a Dual...

We prove that the dual of the digital Voronoi diagram constructed by flooding the plane from the data points gives a geometrically and topologically correct dual triangulation. This provides the proof of correctness for recently developed GPU algorithms that outperform traditional CPU algorithms for constructing two-dimensional Delaunay triangulations.

The ADC16DV160 is a monolithic dual channel high performance CMOS analog-to-digital converter capable of converting analog input signals into 16-bit digital words at rates up to 160 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and external component co...

Developing an efficient high-power transmitter is essential to extend service coverage of terrestrial broadcasting service. Furthermore, it is important to develop a dual-mode transmitter platform that satisfies both ATSC and DVB-T2 in order to reduce development costs. In this paper, we present a design method of dual-mode high-power transmitter with 2.5KW transmit power for terrestrial digita...

A digital edge is a digitization of a straight segment joining two points of integer coordinates. Such a digital set may be analytically defined by the rational slope of the straight segment. We show in this paper that the convex hull, the Euclidean farthest-point Voronoi diagram as well as the dual farthest-point Delaunay triangulation of a digital edge can be fully described by the continued ...
