Study on Storable Down-hole Drilling String Vibration Testing System

Drilling engineering is a high input and risk underground project, which needs the real-time down-hole diagnosis and forecast technique. Drilling string vibration signals contain full and complex vibration waves, which contains the vibration of the drilling string by itself, the vibration stimulated by the interaction of bit and the formation, the vibration induced by colliding between drill st...

Drilling down on Smart Manufacturing -- Enabling Composable Apps

Manufacturing software services provisioned as unbundled "apps" could be significantly more flexible and less expensive to use than the current monolithic manufacturing applications. However, integrating such heterogeneous apps is not a trivial job. National Institute of Standards and Technology (NIST) has initiated a research and development program to advance science and engineering towards t...

Real Time Calibration of Strap-down Three-Axis-Magnetometer for Attitude Estimation

Three-axis-magnetometers (TAMs) are widely utilized as a key component of attitude determination subsystems and as such are considered the corner stone of navigation for low Earth orbiting (LEO) space systems. Precise geomagnetic-based navigation demands accurate calibration of the magnetometers. In this regard, a complete online calibration process of TAM is developed in the current research t...

SpinalTap: An Architecture For Real-Time Vertebrae Drilling Simulation

This report describes the implementation of the SpinalTap virtual spinal surgery simulation system. The goal of the system is to simulate drilling into vertebrae. Two methods for reconstructing a vertebrae from CT scan data are presented. Several models of an L3 vertebrae are reconstructed, with varying results. An architecture for real-time high speed decimation of point volumes is explained a...
