闭合导线测量中边长系统误差分析工程测量闭合导线导线边系统误差在闭合导线测量中,导线边如果存在系统误差,其解算结果仍可能满足现行规范中的各项精度指标.通过一项边长接近的闭合导线测量实例,分析了产生误差的原因与对策,解算出符合要求的测量成果.党四效海军工程设计研究局海洋测绘...
A virtual circuit which traverses a downstream trunk that is momentarily fully utilized will have its bandwidth allocation at the access node decreased, thus avoiding delays and possible data loss at the downstream trunk. At the same time, another virtual circuit originating at the same node and ...
In this work, we present an efficient algorithm for mining δ-tolerance closed frequent subgraphs by incorporating a lot of pruning techniques to cut down the space of enu- merating subgraphs. Our algorithm is closely related with those for mining closed fre- quent subgraphs (by depth-first ...
One instance of this test process identifying the safe path is depicted inFigure 8with several flight trajectories and an elevation profile between points A and B. Ingenuity needed to traverse from A to B while crossing the dynamic terrain regions between the safe airfields marked by the yellow...
The WMR traverses on a flat and horizontal plane. The base and the wheels are rigid, the tires are non-deformable, their contact surface with the ground can be approximated with a point, and there is no mechanical constraint for the steering of the steerable wheels; hence, they are free-...
Thus, this paper proposes CrossFCI, an innovative algorithm that includes a cross-linked itemset storage structure instead of the traditional vertical one, which could traverse each item for more efficiently structure updating. Moreover, benefiting from three proposed pruning strategies, the proposed ...
