More than 2 months later, the same examinees were subjected to bedtime BP monitoring using the CLB (Study 2). To avoid any bias resulting from device order, the second study was performed after a long interval. There were no significant differences in the mean SBP or DBP recorded by using...
The results of this study show that small lower period waves, which carry lower power levels than larger long period waves, are much more common both spatially and temporally. When one considers the benefits of operating a wave energy converter near maximum capacity for a large fraction of the...
