    摘要: A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.

    摘要: The description relates to surgical computer systems, including computer program products, and methods for cumulative buffering for surface imaging. A display image is buffered that has been saved from a previous update. A model representing a tool is subtracted from the buffered display image. The subtracted display image is displayed using a CSG technique at a fixed angle. The subtracted display image is saved. This process is repeated so that the displayed image is cumulatively changed with each change in location of the model representing the tool.

    摘要: A method and system for designing bottom hole assembly configuration. The system and method include modeling the bottom hole assembly by dividing complicated BHA configurations into independent modules and segments. Modules are bounded by two stabilizers where segments are bounded by bottom hole assembly components. A recursive process is used to derive solutions for each of the segments and modules. Only two unknowns (and two non-linear equations) are left when the recursive process reaches to the bit. The two unknowns are then solved by iteration.

    摘要: A method of concealing data in images imperceptibly alters curves therein, such as through adding a value representing the data to be hidden to each of a number of B-spline control points representing the original curve. The altered control points characterize the imperceptibly altered curve, which replaces the original curve in the image. The altered control points may be later extracted from the image and compared with the original control points to determine the hidden value. Prudent selection of the values altering the control points as well as an iterative alignment-minimization algorithm in the detection process provides protection against numerous techniques for preventing the hidden values from being recovered.
