... the high-fidelity information required to accurately excite vehicle models. It is also desirable to minimize the effect of the choice of measurement system used to sample the terrain surface. Nondeformable, anisotropic (path-specific) terrain surfaces are defined as a sequence of vectors, where each vector...

...Heather M. Chemistruck; Robert Binns; John B. Ferris Modern terrain measurement systems use an inertial navigation system (INS) to measure and remove vehicle movement from laser measurements of the terrain surface. Instrumental and environmental biases inherent in the INS produce noise and drift...

... compressible flow measurement systems In industry, flow rate is one of the most important quantity whose measurement requires high accuracy and high dynamic response. The principles of flow rate measurement can be divided into direct and indirect measurements. A number of methods have been proposed 1...
