The mean CO bias between each device and the pooled group CO values, noting individual device variance from the group mean, was -0.2 (LiDCO), 0.4 (FloTrac), -0.2 (PiCCO) and 0.0 L/min (PAC), with limits of agreement (1.96 SD, 95% CI) of ± 1.2 ± 2.4 ± 1.6 and ± 1.4, respectively.
It was shown that a good deal of the devices variance can be captured using only two PCA axes.
There are many factors causing this difficulty, such as the differences between individual animals, the noise of EEG/EMG recording device and variance in surgical techniques used in electrode implantation that can make the definition of rigid boundaries problematic.
Since the devices are not precision cut or cast, there will be variance from device to device.
We show that Monte Carlo simulations of neutral particle transport in planar-geometry anisotropically scattering media, using the exponential transform with angular biasing as a variance reduction device, are governed by a new "Boltzmann Monte Carlo" (BMC) equation, which includes particle weight as an extra independent variable.
Moreover, h i is the target channel gain between the primary transmitter and the i th M2M device receiver with the variance E h i 2 = σ h, i 2,0,i and1,i denote the hypotheses corresponding to the absence and presence of the PU, respectively.
The results presented in this paper show that this device produces consistent low variance injuries of spinal cord, when care is taken to adequately stabilise the vertebral column with clamps onto adjacent vertebrae (see Fig. 1B).
Mean and variances of device characteristics such as drive current (Ion), leakage current (Ioff), subthreshold slope (SS) and threshold voltage (Vt) have been determined from the MC data from both the process simulation and the model equations.
The CoV across the three epochs was calculated from the individual change in values between epochs and used to compare the overall variance between devices.
The three major commercially available monitoring devices, however, do not share the same shoe size - the variance amongst these devices to estimate changing CO is significant [ 9].
