Effect of intradialytic change in blood pressure and ultrafiltration volume on the variation in access flow measured by ultrasound dilution
2013
Kidney Research and Clinical Practice
Preserved Fulltext
Methods: Access flow was measured 30 minutes, 120 minutes, and 240 minutes after the start of HD by ultrasound dilution in 30 patients during 89 HD sessions and evaluated for variation. ...
Conclusion: We conclude that the variation in access flow during HD is relatively small. Decreased blood pressure is a risk factor for variation in access flow measured by ultrasound dilution. ...
Based on our results, we would recommend that any significantly decreased measurement of access flow in a patient in whom MAP had decreased by Z5% should be rechecked at the next session. ...

To implement our approach, we propose to use a two classes CBQ/WRR-like scheduler [6]: one for the unicast flows and the other one for multicast flows. ...

Well established methods such as linear discriminant analysis (LDA), source-normalized LDA (SN-LDA) and within-class covariance normalisation (WCCN) exist for compensating the session variation but we ...
To compensate for utterance variations in short i-vector speaker verification systems using cosine similarity scoring (CSS), we have introduced a short utterance variance normalization (SUVN) technique ...
There are two key recommendations arising from our research for i-vector based speaker verification with short utterances: (i) when a CSS i-vector approach is used, we recommend the use of SUVN [LDA] ...

Based on the observations from our measurements, we develop a model that can estimate the expected performance of a particular stateful firewall when deployed in a customer's network. ...
estimates from our model We evaluate our model on four disparate profiles of normal traffic, which test different variations with respect to protocol type, packet size, and packet counts per flow. ...
We use the term flow (interchangeably with session) in its commonly used sense-a stream of packets with the same five tuple: source and destination IP address, source and destination port, and protocol ...
