This framework was connected to an analytical application which observes changes in systolic, diastolic and mean pressure to determine anomalies in the continuous data stream. Detection was based on an increased mean blood pressure caused by the closing of the withdrawal three-way tap and an absence of systolic and diastolic measurements during this manipulation. For evaluation of the proposed algorithm, measured data from animal studies in healthy pigs were used.RESULTS Using this novel approach for processing real-time measurement data of arterial pressure monitoring, the exact time of blood withdrawal could be successfully detected retrospectively and in real-time. The algorithm was able to detect 422 of 434(97%) blood withdrawals for blood gas analysis in the retrospective analysis of 7 study trials. Additionally, 64 sampling events for other procedures like laboratory and activated clotting time analyses were detected. The proposed algorithm achieved a sensitivity of 0.97, a precision of 0.96 and an F1 score of 0.97.CONCLUSION Arterial blood pressure monitoring data can be used toperform an accurate identification of individual blood samplings in order to reduce sample mix-ups and thereby increase patient safety.展开更多

Sweet sorghum is widely grown by subsistence farmers and matures in 3 to 6 months in February, March and April, before sugarcane harvesting begins. Sweet sorghum has low sucrose content that is difficult to extract during processing. The hypothesis of the study was that sweet sorghum was a potential feedstock to sugarcane mills for the production of sugar and ethanol. The objective of this study was to investigate the trends in starch and sucrose content of four sweet sorghum genotypes namely M337, M81-E, Theis and Topper, and evaluate the potential of sweet sorghum as a feed stock for sugar and ethanol production. The sorghum juice was collected on August 10, August 24, September 8, September 18 and October 2, 2006 and starch and sucrose content were determined. There were significant （P 〈 0.001） genotypes by sampling date interaction effects. Both starch and sucrose content increased with crop sampling date. Genotypes M337 and Theis were late maturing for sucrose content compared to M81-E and Topper. All genotypes except M337 produced no significant increase in starch after 101DAP. Trends in sucrose and starch content were similar, indicating the reason sucrose was difficult to extract from sweet sorghum. The impact of this study would be boosting the incomes of small scale growers who would be subcontracted by the sugar mills to produce sweet sorghum as a feedstock to the mills before sugarcane matures.展开更多
