As an important operator in polygon cluster generalization, the displacement has two applications. One is to resolve the proximity conflicts to guarantee the legibility constraint. Another is to act as the operator prior to other generalization operators, such as aggregation. This paper presents a field based method to deal with the displacement of polygon cluster in both aspects above. On the ...

An online citrate and Ca(2+) sensing system based on sequential injection analysis (SIA) is developed as a safety module for hemodialysis. Host 1 displays high affinity towards citrate, and was selected for this study owing to its unique structural features. The o-aminomethylphenylboronic moiety can effectively interact with the α-hydroxycarboxylate moiety of citrate and the remaining two guani...

ing away from much of the technical machinery employed by Bresnan here and in what follows, let me clarify the key notions involved here. A transformation T is an ordered pair , where C is a structural condition consisting of a number of terms, and M is a transformational mapping affecting these terms. The wh-movement transformation, e.g., can be encoded as the pair in (54) (I tacitl...

Understanding of the dynamics of the heart is required for the prevention and treatment of cardiac related diseases as well as for the design of pacemakers and artiicial hearts. We present a new method for the analysis of myocardium motion and deformation based on the study of velocity encoded NMR images. By applying a few mathematical operators on the semi{automatically segmented image of the ...

Studies show that there is electric potential difference between the internal part of tree and the soil, but the mechanism is not clear, possibly associated with tree species, environmental factors and DBH (diameter at breast height) of tree. In order to research the mechanism and change rules, it is necessary to measure bioelectricity, environmental factors and DBH of tree, among which the DBH...

Robotic grasping of deformable objects is inherently different from that of rigid objects, and is an under-researched area. Difficulties arise not only from expensive deformable modeling, but also from the changing object geometry under grasping force. This dissertation studies strategies of grasping deformable objects using two robotic fingers. Discovering the inapplicability of the traditiona...

We propose a new representation for multiresolution models which uses volume elements enclosed between the different resolution levels to encode the detail information. Keeping these displacement volumes locally constant during a deformation of the base surface leads to a natural behaviour of the detail features. The corresponding reconstruction operator can be implemented efficiently by a hier...
