说明：Fingerprint matching systems generally use four types of representation schemes: grayscale image, phase image, skeleton image, and minutiae, among which minutiae-based representation is the most widely adopted one. The compactness of minutiae representation has created an impression that the minutiae template does not contain sufficient information to allow the reconstruction of the original grayscale fingerprint image. This belief has now been shown to be false; several algorithms have been proposed that can reconstruct fingerprint images from minutiae templates. These techniques try to either reconstruct the skeleton image, which is then converted into the grayscale image, or reconstru

说明：suggests the use of contourlet transform for efficient feature extraction of fingerprints for identification purposes. Back propagated neural network is then used as a classifier. Two fingerprints databases are used to test the system. These include fingerprints images with different positions, rotations and scales to test the robustness of the system.

说明：This article is a contribution to the study of hybrid photovoltaic systems for electrical energy producing associated with a storage system for isolated site. In this context, we have proposed mathematical models that govern the physical functioning of each part of the system studied depending on meteorological conditions or estimated data.

说明：In this work, we study vector control and sliding mode control of series-connected five-phase two asynchronous machines supplied with a three levels inverter.

说明：The aim of this work is to investigate the optical transmission properties of the multilayers containing negative refractive index metamaterials. In the design procedure, the transfer matrix method is used to determine the transmission and reflection coefficient of structure for TE (transverse electric) and TM (transverse magnetic) modes.

说明：ZKLibrary is PHP Library for ZK Time & Attendance Devices. This library is design to reading and writing data to attendance device (fingerprint, face recognition or RFID) using UDP protocol. This library is useful to comunicate between web server and attendance device directly without any addition program. This library is implemented in the form of class. So that you can create an object and use it functions. Web server must be connected to the attendance device via Local Area Network (LAN). The UDP port that is used in this communication is 4370. You can not change this port without changing firmware of the attendance device. So, you just use it. The format of the data are: binary, string, and number. The length of the parameter and return value must be vary.
