A method and system for performing fault tolerant static timing analysis for an electronic network. A composite timing graph is generated by making K+1 copies of the zero-defect timing graph of the network, where K is a predetermined maximum number of defects present on a path of the network, and static timing analysis is performed on the composite timing graph.

The invention relates to a method for detecting atypical electronic components for the quality control of n electronic components at the end of the manufacturing process, said components being subjected to a number p of unit tests providing digital data, said set of n components including electronic components having a response to each of the p unit tests that lies within predetermined limits particular to each of the p tests, wherein the method comprises using the multi-dimensional information of the p dimension responses of said n electronic components. The method uses a generalised principal component analysis for detecting atypical parts in the semiconductor field, or in the fields including modules assembled using electronic components (e.g. an ABS module, a smart card, etc.). The aim of the method is to get close to "zero defect", wherein no part is detected to be substandard by the client.

The invention relates to a rapid drying method for a cottonwood thick plate, and the method comprises the following steps of: at a preprocessing stage of a cottonwood, sawing the cottonwood to be plates with certain length and thickness according to operating requirements, stacking the plates and placing the plates into preprocessing equipment, then carrying out superheated steam preprocessing, and drying the preprocessed plates according to strengthening benchmark. In the rapid drying method, at the preprocessing stage of the cottonwood, constant-pressure superheated steam with temperatures of 110 DEG C-160 DEG C is used as a processing medium, therefore, not only can smooth and zero-defect of plate surfaces of the processed cottonwood be achieved, but also growth stress of the cottonwood can be released, a water passage inside a wood is opened, initial water ratio of the plates can be substantially reduced. A green wood is preprocessed, water ratio descending ratio is 40%-80%, descending mean value of the water ratio is above 60%,so that a drying stage time in a later period of the cottonwood can be greatly shortened. Compare with the conventional drying method, drying cycle is shortened above one half, energy sources are saved, drying cost is reduced, drying quality is favorable, and the rapid drying method is particularly applicable to cottonwood plates with thickness more than 5.0cm.

The invention discloses a lossless real-time detecting method and system for a magnetic conductive material. The lossless real-time detecting method comprises the following steps of: collecting a signal of the magnetic conductive material after being magnetized by a giant magneto resistive sensor, and comparing the collected signal with a normal value of the magnetic conductive material under a zero defect state in the prior art and a typical value of reluctance change under the existence of interior defect so as to judge the flow of the inner magnetic field in the present position of the magnetic conductive material and the magnetic field diffusing state in the position of defect. A system adopted by the method comprises N sets of GMR (Giant Magneto Resistive) sensor chipsets, a lower computer control module, a magnetizing device, an alarm device, a data collecting and processing module and an upper computer, wherein the magnetizing device is used for realizing the magnetization and demagnetization of the magnetic conductive material; the sensor chipsets are used for sensing the change of reluctance change of the magnetic conductive material; and the data collecting and processing module is used for processing an analog signal collected by the sensor chipsets and then comparing with the typical value and an ideal value. The lossless real-time detecting method is low in detection cost, is used for effectively detecting a strange part and does not threaten a human body.
