117 results about "Case analysis" patented technology

Case analysis is one of the most general and applicable methods of analytical thinking, depending only on the division of a problem, decision or situation into a sufficient number of separate cases. Analysing each such case individually may be enough to resolve the initial question. The principle of case analysis is invoked in the celebrated remark of Sherlock Holmes, to the effect that when one has eliminated the impossible, what remains must be true, however unlikely it seems. The logical roots of the Holmes remark speak to the principle of excluded middle. That indicates the importance to case analysis of logical disjunction: stringing together propositions with the logical connective "or". Medical diagnosis can indeed follow the Holmes pattern, with a patient's symptom possibly caused by a number of conditions: the patient suffers from A or B or ... or illness I; see differential diagnosis. Deductive logic is applied to reducing the number of cases; see case-based reasoning. A canonical statement of case analysis in the sentential calculus is this: "If a statement P implies a statement Q, and a statement R also implies Q, and either P or R is true, then Q must be true."

Automatic steel plate surface defect recognition method based on case-based reasoning

The invention provides an automatic steel plate surface defect recognition method based on case-based reasoning in order to solve the problems that a mechanism model used for recognizing steel plate surface defects is difficult to establish, which does not facilitate detection and control of product quality. The automatic steel plate surface defect recognition method automatically recognizes seven defects of cracks, scaling, scarring, humping and others. A case-based reasoning recognition model is established through the steps of case library establishing, weight allocation, target case obtaining, numerical value normalization, case retrieval, case reusing, case storing and others. A recognition algorithm is implemented, so that recognition accuracy is improved. The problem that due to subjectivity and uncertainty of allocating case-based reasoning characteristic variable weights, the recognition accuracy rate is low is solved. The experiment result shows that the method can accurately recognize the defects on the surface of a steel plate and is good in sensitivity and distinctness, the processing efficiency of the defects on the surface of a steel plate is improved, the rejection rate is decreased, and the method is of great significance to case analysis on the defects on the surface in the production process of the steel plate, production operation method improving and product quality improving.

Systems and methods for circuit lifetime evaluation

Systems and methods for estimating the lifetime of an electrical system in accordance with embodiments of the invention are disclosed. One embodiment of the invention includes iteratively performing Worst Case Analysis (WCA) on a system design with respect to different system lifetimes using a computer to determine the lifetime at which the worst case performance of the system indicates the system will pass with zero margin or fail within a predetermined margin for error given the environment experienced by the system during its lifetime. In addition, performing WCA on a system with respect to a specific system lifetime includes identifying subcircuits within the system, performing Extreme Value Analysis (EVA) with respect to each subcircuit to determine whether the subcircuit fails EVA for the specific system lifetime, when the subcircuit passes EVA, determining that the subcircuit does not fail WCA for the specified system lifetime, when a subcircuit fails EVA performing at least one additional WCA process that provides a tighter bound on the WCA than EVA to determine whether the subcircuit fails WCA for the specified system lifetime, determining that the system passes WCA with respect to the specific system lifetime when all subcircuits pass WCA, and determining that the system fails WCA when at least one subcircuit fails WCA.
