《物权法》的实施对我国船舶登记制度的影响

物权是指权利人依法对特定的物享有直接支配和排他的权利,包括所有权、用益物权和担保物权。随着《物权法》的实施,船舶所有权、抵押权、留置权等有关的物权制度得以清晰和明确。文中从船舶所有权、抵押权等方面分析了《物权法》的实施对我国现行船舶登记制度的影响。

Developing a Spatially Enabled Inventory of Recreational Boats Using Vessel Registration Data

Effective waterway management requires information on the characteristics and locations of boats. A field-based boat census—a traditional method to obtain spatially accurate information—is relatively expensive, time-consuming, and restrictive in scope. Vessel registration data, maintained by all U.S. states, is potentially a more robust information source. This research evaluated the accuracy and reliability of vessel registration data to supply location and attribute information for boats. The study premise was to use vessel registration data, which includes the mailing address of registered boat owners, to develop a spatially enabled inventory of boats. The study area comprised 12,064 salt-water accessible property parcels in two Florida counties. An on-water census (OWC) provided location and characteristics for 5,023 vessels, which were compared to 8,681 vessel registration records linked to the study area. Discrepancies between the OWC and vessel registration data were explained by a stratified, random sample of 485 telephone survey respondents. Study results show that vessel registration data accurately located and characterized roughly 81% of the boat population; in contrast, the OWC accurately located less than 56%. A conclusion is that state vessel registration data is a better alternative than an OWC for locating and characterizing boats kept along waterways.     

融资租赁船舶所有权登记

从国际船舶融资的角度看,缺少船舶融资租赁权登记规定的船舶登记制度,是不利于跨国船舶融资租赁的。我国《船舶登记条例》中有关光船租赁权登记制度的基本精神和具体做法可为船舶融资租赁权登记制度提供有益借鉴。但仍存在一些不足,笔者试着从这方面提出若干建议。     

论船舶登记的公信力

公信力理论起源于德国,是登记的理论基础。文中从物权的公示和公信力理论出发,剖析公信力理论的内涵、现实意义、在国外的适用情况,并联系我国船舶登记的实际情况,阐述公信力理论在我国建立的必要性和可行性,提出可通过引入船舶登记前置的公证程序和变更异议登记制度等途径进一步提高和完善船舶登记的公信力。

Hierarchical Non-linear Image Registration Integrating Deformable Segmentation

IntroductionSegmentation and registration are two impor-tant problems in the field of medical image analy-sis. Traditionally, solutions have been developedfor each of these two problems in relative isolationfrom the other, but with increasing dependence onthe existence of a solution for the other. For exam-ple, model-based segmentation methods[1,2]need toregister individual data sets to a common frame ofreference, so that statistics about the models canbe gathered to guide the evolution of the…

基于共轭梯度的大尺度医学图像非刚性配准算法

人体胸腹腔中大量非刚性软组织器官由于呼吸、脏器蠕动和体位变动等会产生大尺度非线性形变,粘性流体配准将图像的形变模拟为流体的流动过程而适宜于大的形变.针对粘性流体配准算法应用超松驰迭代求解离散化偏微分方程组耗时量大,且其最优松驰参数难以获得的问题,使用基于不需要预先估计参数的共轭梯度迭代求解形变参数,实现粘性流体配准.该方法所需存储量小,且具有步收敛性、稳定性高的优点,实验证明该方法在不损失配准精度的前提下提高了配准速度.     

基于尺度不变特征的水下图像双向定位配准(英文)

For the purpose of identifying the stern of the SWATH(Small Waterplane Area Twin Hull) availably and perfecting the detection technique of the SWATH ship's performance, this paper presents a novel bidirectional image registration strategy and mosaicing technique based on the scale invariant feature transform(SIFT) algorithm. The proposed method can help us observe the stern with a great visual angle for analyzing the performance of the control fins of the SWATH. SIFT is one of the most effective local features of the scale, rotation and illumination invariant. However, there are a few false match rates in this algorithm. In terms of underwater machine vision, only by acquiring an accurate match rate can we find an underwater robot rapidly and identify the location of the object. Therefore, firstly, the selection of the match ratio principle is put forward in this paper; secondly, some advantages of the bidirectional registration algorithm are concluded by analyzing the characteristics of the unidirectional matching method. Finally, an automatic underwater image splicing method is proposed on the basis of fixed dimension, and then the edge of the image's overlapping section is merged by the principal components analysis algorithm. The experimental results achieve a better registration and smooth mosaicing effect, demonstrating that the proposed method is effective.
