Anchor Modeling
Did you know that some of the earliest prerequisites for data warehousing were set over 2500 years ago. It is called an anchor model since the anchors tie down a number of attributes (see picture above). All EER-diagrams have been made with Graphviz. All cats are drawn by the author, Lars Rönnbäck. 2 2 You can never step into the same river twice. 2 The great greek philosopher Heraclitus said "...
متن کاملIntegrins anchor the invasive machinery.
Cell invasion through the basement membrane, a process important for both development and disease pathogenesis, depends on an interplay of adhesive, force transducing, proteolytic, and chemotactic machineries. The mechanisms whereby these different processes are integrated on the cellular level have remained elusive. In this issue of Developmental Cell, Sherwood and coworkers now identify integ...
متن کاملAnchor 2005
Flow tracking is an integral aspect of many network-related applications, including intrusion detection, network administration, per-flow billing, and network engineering. While some applications do not require precise tracking of every packet or flow and successfully employ statistical sampling or approximations to achieve an acceptable level of accuracy, many others, especially in the securit...
متن کاملAn algorithm for the anchor points of the PPS of the CCR model
Anchor DMUs are a new class in the general classification of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). An anchor DMU in DEA is an extreme-efficient DMU that defines the transition from the efficient frontier to the free-disposability part of the boundary of the Production Possibility Set (PPS). In this paper, the anchor points of the PPS of the CCR model are investigated....
متن کاملA Selective 3-Anchor DV-Hop Algorithm Based On the Nearest Anchor for Wireless Sensor Network
Abstract—Information of nodes’ locations is an important criterion for lots of applications in Wireless Sensor Networks. In the hop-based range-free localization methods, anchors transmit the localization messages counting a hop count value to the whole network. Each node receives this message and calculates its own distance with anchor in hops and then approximates its own position. However th...
