Enhancement of height system for Malaysia using space technology: the study of the datum bias inconsistencies in Peninsular Malaysia by Mohd. Omar, Kamaludin, Ses, Shahrum, Mohamed, Azhari

“…It is therefore necessary to take into account the effect of inconsistent datum bias particularly for baseline height transfer. The level of accuracy achieved by the bias corrected relative orthometric height differences of the EGM96, OSU91A and the gravimetric geoid models combined with GPS/leveling data for baseline lengths up to 36 km, is sufficient to replace the conventional tedious, time consuming ordinary leveling technique for rapid height transfer for land surveying and engineering applications.…”

Longer prehospital time was not associated with mortality in major trauma. A retrospective cohort study. by Brown, E., Tohira, Hideo, Bailey, P., Fatovich, D., Pereira, G., Finn, J.

“…Inverse probability of treatment weighting (IPTW) using the propensity score was performed to limit selection bias and confounding. The primary outcome was 30-day mortality and the secondary outcome was the length of hospital stay (LOS) for 30-day survivors. …”

Impact of timely dialysis on mortality in patients needing emergency hemodialysis / Norfariza Abd Rahim by Norfariza, Abd Rahim

“…In addition, we need to adjust the potential confounders in this study such as to determine medical diagnosis of patients upon admission and to evaluate time of admission to time of HD among these patients to prevent bias that can distort the result in this study. …”

Bridging Real-Time Precise Point Positioning in Natural Hazard Warning Systems during Outages of MADOCA Corrections by El-Mowafy, Ahmed, Deo, Manoj

“…The best regression period to estimate the required model parameters is discussed based on autocorrelation analysis of the corrections. The time lengths of the sinusoidal terms are estimated from analysis of the data in the frequency-domain. …”

Detection of linear trends in multi-sensor time series in the presence of autocorrelated noise: Application to the chlorophyll-a SeaWiFS and MERIS datasets and extrapolation to the... by Saulquin, B., Fablet, R., Mangin, A., Mercier, G., Antoine, David, Fanton d'Andon, O.

“…Although the noise autocorrelation observed in geophysical time series does not bias the trend estimate, it affects the estimation of its uncertainty and consequently the ability to detect, or not, a significant trend. …”

The Reliability of Spatiotemporal Gait Data for Young and Older Women During Continuous Overground Walking by Paterson, K., Hill, Keith, Lythgo, N., Maschette, W.

“…Results: The relative and absolute measures of reliability showed most spatiotemporal variables recorded during the single and continuous walking protocols were reliable. Step length, foot angle, and step and stance times were found to be the most reliable parameters, with ICCs ranging from 0.84 to 0.95, CVs from 2.06% to 4.02%, and SE of measurements of 1.59 to 2.04cm for step length, 1.32° to 1.71° for foot angle, and 0.011 to 0.025 seconds for step and stance times. …”

Improving ambiguity resolution and cycle slip detection from combined triple-frequency GNSS observations by Zhao, Dongsheng

“…In order to detect and correct cycle slips under the observation condition of high ionospheric activities, this thesis modifies the detection process of the previous method and reselects the combined triple-frequency signals by minimizing the measurement noise without considering the ionospheric bias. The first-order time-differenced ambiguity is applied with a proposed outliers elimination method, the ionospheric trend in it can be obtained by applying the robust locally weighted scatter plot smoothing technique. …”

Investigating the effect of independent blinded digital image assessment on the STOP GAP trial by Patsko, Emily, Godolphin, Peter J., Thomas, Kim S., Hepburn, Trish, Mitchell, Eleanor, Craig, Fiona E., Bath, Philip M.W., Montgomery, Alan A.

“…Background Blinding is the process of keeping treatment assignment hidden and is used to minimise the possibility of bias. Trials at high risk of bias have been shown to report larger treatment effects than low risk studies. …”
