Few views image reconstruction using alternating direction method via ‐norm minimization

In the medical computer tomography field, total variation (TV), which is the ‐norm of the gradient‐magnitude images, is widely used as the regularization based on the compressive sensing theory. To overcome the TV model's disadvantageous tendency of uniformly penalize the image gradient and over smooth the low‐contrast structures, an iterative algorithm based on the ‐norm optimization of the finite difference is proposed. To rise to the challenges introduced by the ‐norm minimization, the algorithm uses the alternating direction method to solve the unconstrained augmented Lagrangian function, which involves a hard thresholding method, a linearization and proximal points technique for each subproblem. The simulation demonstrates the conclusions and indicates that the algorithm proposed in this article can obviously improve the reconstruction quality. © 2014 Wiley Periodicals, Inc.

Personal Reflections on 60 Years of Psychology: Many Roads to Truth.

The author selects from her 60 years of personal experiences examples of conflicting views within the profession of psychology on the means of discovering and creating knowledge and truth. She presents vignettes of differences that occur within professional education, research, the regulation of the profession, and beliefs about diversity. Aspirational ethics, as in the Canadian Code of Ethics for Psychologists, is inspiring and unifying in using moral principles to bring together apparently divergent people and divergent views to serve our common humanity. Diversity can enrich. CPA's motto of "Advancing Psychology for All" is a commitment to place the welfare of society individually and collectively above self-interest.

An enhanced neutral object-oriented data model

A neutral object-oriented data model is necessary to provide separation of application data views from physical data storage in industrial software systems. This short note suggests that a semantically enhanced object data model beyond that of current language-oriented models will be necessary to provide robust capabilities.     

Specification of internal accounting controls in a database environment

This paper examines the problem of specifying database security controls in a manner such that the resulting segmentation of data and the patterns of access rights are consistent with traditional accounting concepts that govern segregation of duties. The mechanism we use for implementation of these controls in a relational accounting system is that of a “view” implemented on the Query-by-Example database management system. A number of examples are presented in detail and some further aspects of security and integrity constraints are discussed.     

Logical data base design: A management-oriented approach

A logical data base consists of data definitions and data relationships. It is typically very large and complex even for a small organization, but it is generally designed in an ad hoc manner. However, several approaches have recently been proposed that allow for a systematic logical data base design.To make a data base more useful to the managers, it is imperative to encourage and obtain their involvement in the initial phase of the logical data base design. “Surface semantic models” are used in the logical data base design process to increase this involvement. A special type of this, called a “hierarchical external view model”, is proposed. It has been successfully used to develop a logical data base for the Department of Aging in Pennsylvania.     

短牛腿抗剪强度的敏感性因素分析

利用正交试验设计法对影响钢筋混凝土短牛腿抗剪承载力的各因素进行分析,考虑的因素包括混凝土抗压强度、剪跨比和钢筋屈服强度。通过分析可知剪跨比对短牛腿抗剪强度最为敏感,混凝土抗压强度和钢筋屈服强度次之。希望本文内容可作为进一步研究钢筋混凝土短牛腿受力性能的依据。
