A method and system for employee life cycle management collects occupational health data from a plurality of diverse occupational health data sources for a plurality of employees, stores the collected data in a central database, processes the data to generate employee life cycle data, stores the employee life cycle management data in the database, and centrally manages the employee life cycle management data to make the employee life cycle data available to at least one employer.
摘要:
An aluminum alloy sheet is manufactured by preparing a slab having a thickness of 5 to 15 mm with a continuous casting machine by a continuous casting process using molten alloy containing following components: 0.40% to 0.65% of Mg, 0.50% to 0.75% of Si, 0.05% to 0.20% of Cr, and 0.10% to 0.40% of Fe, remainder being Al, the components being essential elements, and optionally up to 0.15% Cu, 0.10% Ti; winding the slab into a coil; hot-rolling or directly coiling up the slab; cold-rolling the slab into a sheet; subjecting the sheet to solution heat treatment with a continuous annealing furnace; and then pre-aging the sheet. The aluminum alloy sheet has the same composition as the molten alloy, has a grain size of 10 to 25 μm, is superior in bake hardenability, bendability, and surface quality (orange peel), and can be manufactured with low cost.
摘要:
A method for training a pattern recognition algorithm including the steps of identifying the known location of the pattern that includes repeating elements within a fine resolution image, using the fine resolution image to train a model associated with the fine image, using the model to examine the fine image resolution image to generate a score space, examining the score space to identify a repeating pattern frequency, using a coarse image that is coarser than the finest image resolution image to train a model associated with the coarse image, using the model associated with the coarse image to examine the coarse image thereby generating a location error, comparing the location error to the repeating pattern frequency and determining if the coarse image resolution is suitable for locating the pattern within a fraction of one pitch of the repeating elements.

摘要:
A method for training a pattern recognition algorithm for a machine vision system that uses models of a pattern to be located, the method comprising the steps of training each of a plurality of models using a different training image wherein each of the training images is a version of a single image of the pattern at a unique coarse image resolution, using the models to identify at least one robust image resolution where the image resolution is suitable for locating the pattern within an accuracy limit of the actual location of the pattern in the image and storing the at least one robust image resolution for use in subsequent pattern recognition processes.
