Biometric systems have for objective to perform identification, or verification of identity of individuals. Human electrocardiogram (ECG) has been recently proposed as an additional tool for biometric applications. Then, a set of ECG-based biometric studies has occurred in the literature but they are difficult to compare because they use various values of: the number of ECG leads, the length of...

In order to reduce the failure probability of rubber sealing rings in reciprocating dynamic seal, a new structure of sealing ring based on bionics was designed. The biomimetic ring has three concave ridges and convex bulges on each side which are very similar to earthworms. Bulges were circularly designed and sealing performances of the biomimetic ring in both static seal and dynamic seal were ...

Various inverse algorithms have been proposed to estimate brain electrical activities with magnetoencephalography MEG and electroencephalography EEG . To validate and compare the performances of inverse algorithms, many researchers have used artificially constructed EEG and MEG datasets. When the artificial sources are reconstructed on the cortical surface, accuracy of the source estimates has ...

We show that the set of realizations of a given dimension of a max-plus linear sequence is a finite union of polyhedral sets, which can be computed from any realization of the sequence. This yields an (expensive) algorithm to solve the max-plus minimal realization problem. These results are derived from general facts on rational expressions over idempotent commutative semirings: we show more ge...

Hangzhou has launched a new performance evaluation mechanism by selecting satisfying or dissatisfying units with the features of openness and elimination systems. It announces the idea of making the citizens understand, participate and support. It also increases the comparability and impartiality and expands the scope of participation. By classifying the sub-categories, applying coefficient, in...

Most studies of managed fund performance use measures that are susceptible to bias caused by common time variation in risks and risk premia. Ferson and Schadt (1996) propose a conditional performance measure that controls for the common variation. Their results suggest that incorporating lagged public information variables that have been shown to predict stock returns, such as interest rates an...

A quantitative analysis method for fudosteine in human serum by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI/MS/MS) was established, which shows high sensitivity and selectivity. The mobile phase composition was 75% 20 mM acetic acid and 25% acetonitril, which was pumped at a flow rate of 0.40 mL/min. The overall chromatographic run time was ...

A number of measures of canonical correlation coefficient are now used in multimedia related fields like object recognition, image segmentation facial expression recognition and pattern recognition in the different literature. Some robust forms of classical canonical correlation coefficient are introduced recently to address the robustness issue of the canonical coefficient in the presence of o...
