Finger-vein recognition as a non-contact biometric technique has its inherent superiority on accuracy, speed, sanitation, maintenance and security. However, we found that due to posture changes when acquiring finger images, the discrepancy between different images from the same finger greatly lowers the performance of the entire system. In this paper, we(More)
In this thesis, we develop tools and methods to assist in veriication of large software systems. In particular, we will apply the complete coverage principle to generate test cases automatically from tabular expressions used in software documentation. Multi-dimensional expressions called tables are used in software documentation so that formal documentation(More)
Double-lumen endotracheal tube (DLET) anaesthesia is the commonly used method in minimally invasive oesophagectomy (MIE). However, DLET intubation does have its disadvantages. Firstly, the placement of the DLET needs a skilled anaesthetist with familiarity of the technique and subsequent ability to perform a fibre-optic bronchoscopy for confirmation.(More)
Biometric menagerie is an important phenomenon in biometric systems, which focuses on distinguishing the minority of people who perform poorly and cause the majority of the errors (FAR and FRR). It can help to evaluate biometric systems and improve their performance by analyzing the animal like users. The fundamental step of this theory is the detection of(More)
Aiming at the situation of lacking automation and informatization for the tunnel construction ventilation, this article proposed a monitoring system based on the fieldbus technology. The monitoring system consisted of three parts including the monitor cabinet, the local control cabinet and the fieldbus sensors. A monitoring program, which was written by the(More)
Finger vein verification has developed a lot since its first proposal, but there is still not a perfect algorithm. It is proved that algorithms with the same overall accuracy may have different misclassified patterns. We could make use of this complementation to fuse individual algorithms together for more precise result. According to our observation,(More)
