investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The Interval Geometric Machine.∗
The Geometric Machine model (GM) is introduced in [4, 3] to allow the construction and the representation of concurrent and nondeterministic computations, performed in a synchronized way by multiple processes operating on array structures. That means, a mathematical model to represent the real-time behavior of processes. We take use of the advantages of coherence spaces [2] to obtain the domain...
متن کاملChecking Geometric Programs or Verification of Geometric Structures1
A program checker verifies that a particular program execution is correct. We give simple and efficient program checkers for some basic geometric tasks. We report about our experiences with program checking in the context of the LEDA system. We discuss program checking for data structures that have to rely on user-provided functions.
متن کاملEvaluation of the truebeam machine performance check (MPC) geometric checks for daily IGRT geometric accuracy quality assurance
Machine Performance Check (MPC) is an automated and integrated image-based tool for verification of beam and geometric performance of the TrueBeam linac. The aims of the study were to evaluate the performance of the MPC geometric tests relevant to OBI/CBCT IGRT geometric accuracy. This included evaluation of the MPC isocenter and couch tests. Evaluation was performed by comparing MPC to QA test...
متن کاملIkonos Geometric Accuracy Validation
Since its launch in September of 1999, the IKONOS satellite has been consistently providing high quality 1-meter panchromatic and 4-meter multispectral images. Accurate interior and exterior orientation enable IKONOS to achieve high geometric accuracy with or without ground control. Exterior orientation is determined by on-board GPS receivers, star trackers, gyros, and interlock angles. Post-pr...
