A study of simulated annealing and a revised cascade algorithm for image reconstruction

We describe an image reconstruction problem and the computational difficulties arising in determining the maximum a posteriori (MAP) estimate. Two algorithms for tackling the problem, iterated conditional modes (ICM) and simulated annealing, are usually applied pixel by pixel. The performance of this strategy can be poor, particularly for heavily degraded images, and as a potential improvement Jubb and Jennison (1991) suggest the cascade algorithm in which ICM is initially applied to coarser images formed by blocking squares of pixels. In this paper we attempt to resolve certain criticisms of cascade and present a version of the algorithm extended in definition and implementation. As an illustration we apply our new method to a synthetic aperture radar (SAR) image. We also carry out a study of simulated annealing, with and without cascade, applied to a more tractable minimization problem from which we gain insight into the properties of cascade algorithms.

协同运输管理运行机制研究

协同运输管理是在CPFR基础上发展起来的一种供应链管理方法。它通过降低供应链中的运输成本、缩短商品交付时间和提高准时交货率,实现供应链价值的最大化。协同运输管理的有效实施,需要建立完善的运行机制,包括动力机制、约束机制、实际行为和惩罚机制,并配备相应的软硬件条件。     

Doing Gender unto the Other: Fiction as a Mode of Studying Gender Discrimination in Organizations

Although ‘doing gender’ has been recently defined as an accomplishment, an element of social practice, this understanding of the concept needs to be extended to coercive action such as subtle workplace discrimination. Even though great effort has been invested in revealing the dynamic of such social practices, the researcher's task is not easy for a variety of reasons. This type of study is difficult to conduct by following traditional research design and many alternative approaches have been tried. This article presents the possibility of using fiction as one possible and relatively unexploited venue of research.
