不动产物权变动登记外的公示方式

按现有立法,不动产物权变动的公示方式均是登记。但立法上却有不登记的例外,实践中也有这种需要。如果法律上能够明确,在一定条件下,不动产的物权变动可以以登记外的公示方式存在,它对于保障交易安全、提高交易效率具有较强的现实意义。为了减少负面效应——实施这种公示方式可能出现的问题,如二重买卖、重复抵押等,可采取相应的措施予以解决。

县(市)教育技术装备站档案资料管理初探

档案资料管理,是县(市)教育技术装备站的一项最根本、最经常性的工作,是实施外部管理的基础。注重资料的长期积累与保存,既是县(市)教育技术装备站建好内部管理档案的重要环节,也是指导基层实验教学及管理工作的重要依据。几年来,我们在档案资料管理中,试行“抓‘四性’,促‘三个服务’”的工作模式,有效地促进了站内资料的规范化管理,强化了资料管理的服务功能。

A New Feature-Based Image Registration Algorithm

IR （Image Registration） is one of the important operation of image processing system which is the process of aligning two or more images into one coordinate system that are taken at different times, from different sensors, or from different viewpoints. It has a lot of applications especially medical imaging and remote sensing. The main purpose of this paper is to provide a comprehensive review of existing literatures available on image registration system and proposed a new feature-based IR technique using edge of images. We used edges as a feature of images for registration. It will be a useful document for researchers who will work on feature-based image registration regardless for specific applications.
