A Fast MAP Algorithm for High-Resolution Image Reconstruction with Multisensors

In many applications, it is required to reconstruct a high-resolution image from multiple, undersampled and shifted noisy images. Using the regularization techniques such as the classical Tikhonov regularization and maximum a posteriori (MAP) procedure, a high-resolution image reconstruction algorithm is developed. Because of the blurring process, the boundary values of the low-resolution image are not completely determined by the original image inside the scene. This paper addresses how to use (i) the Neumann boundary condition on the image, i.e., we assume that the scene immediately outside is a reflection of the original scene at the boundary, and (ii) the preconditioned conjugate gradient method with cosine transform preconditioners to solve linear systems arising from the high-resolution image reconstruction with multisensors. The usefulness of the algorithm is demonstrated through simulated examples.     

造纸厂资产管理欧洲视野:2007现状及趋势预测

设备维护费用是制造加工业运营成本中一项主要的费用支出,大约占生产成本的15%～40%.在不同的行业中维护费用有所不同,如食品加工业的平均维护费用约为生产成本的15%,而在制浆造纸业中,平均维护费用约为生产成本的40%.     

Cattaneo公司从胶印向柔印的转型

在过去的几年里.西欧国家标签市场一直呈现每年3%～6%的增长,而商业印刷市场的表现却是增长停滞,甚至有所下降.这种情形下,越来越多的原先采用单张纸胶印的商业印刷商开始把目光投向了持续增长的卷筒纸标签印刷业务,位于意大利米兰附近的Cattaneo公司就是其中的一家.这家成立于1920年的家族公司,主要业务是印制商业印刷品,包括书籍、海报等,从20世纪70年代开始,他们便使用轮转胶印表格机从事商业表格印刷.     

印刷企业积极进取的力量

Julie：在过去的几周里，美国和世界金融市场经历了非常困难的时期。世界上一些大型的银行机构和投资公司纷纷破产或由政府接管。在未来的几周里，世界各地可能会有更多的金融公司带来更多的坏消息。许多金融专家们对世界经济充满沮丧和悲观的情绪。

Oxidation with air of cyclohexanone to carboxylic diacids on carbon catalysts

Carbons derived from phenolic resins were used as catalysts for the aqueous phase oxidation of cyclohexanone at 140°C under air pressure. The reaction yielded mainly adipic, glutaric and succinic acids. The samples were modified by heat treatments in CO₂, air or N₂ at different temperatures and characterized to determine their surface area and porosity and to evaluate the functional groups on the surface. Treatments under CO₂ or air increased the oxidation activity. The selectivity to adipic acid was maximum (33%) after activation in air which greatly increased the surface concentration of oxygen-containing functional groups. However, it was not possible to attribute the selectivity to specific acidic, neutral or basic groups present at the surface of carbons. This revised version was published online in June 2006 with corrections to the Cover Date.

Parallel processing of the sex and familiarity of faces.

78 undergraduates were asked to rate photographs of faces as male or female and familiar or unfamiliar under a total of 4 conditions in 2 experiments. Results from Exp I indicate that faces whose sex was difficult to classify were no harder to judge as familiar than those whose sex was easy to classify. In Exp II this result was replicated and extended to a situation where the familiarity judgment was contingent on the sex judgment. Findings support the view that analyses of the face's sex and its identity proceed in parallel, rather than in hierarchical, order as claimed by H. Ellis (1986).
