resection

1. (medicine) To excise part or all of a tissue or organ.Examples: "Most articles published after this date, however, mention the resectioning of fat around the eyes as an essential constituent of corrective lid surgery."; "...these problems and the overwhelming numbers of wounded men flooding into hospitals after battles meant that amputations and resectioning of joints (the removal of bones) became standard protocol."; "Anyway, they did the operation, removed a huge lump, resectioned my colon, and gave me the news that they thought that the tumour hadn't spread."

2. (surveying) To determine positions using compass bearings based on three or more known positions.Examples: "The Senior class was drilled in the use of the plane table; in resectioning on unknown points, the "three point problem," etc."; "After construction of earthwork is completed the work should be resectioned and the estimates for final payment made according to the information thus obtained."; "For an independent check of the work, and a better indication of its accuracy, the point should be resectioned, as described in the next section."

3. (digital image processing) To estimate a camera projection matrix from known position data and image entities.Examples: "The camera matrices and 3D structure are then computed for the frames 1-2-3-4, for example by first resectioning and then bundle adjustment."; "Based on the convex cone, they give a further improved method for homography and camera resectioning'."; "The cost can be immediately reduced by only using key frames for the initial reconstruction, and then resectioning the other frames."

4. (education) To transfer students into new class groupings or grade levels.Examples: "In connection with a scheme of resectioning, a number of questions naturally present themselves. When the students complete their first term or first year of the subject in the most efficient, intermediate, and least efficient sections, what process of equalization is going to occur at the beginning of the second term or year?"; "This is easily understandable when, with resectioning, a cadet is offered the opportunity to underperform with the only punishment being an easier class!"; "Tully's class was initially assigned to sections alphabetically and then resectioned later in the year according to academic merit."

5. (civil engineering) To deepen or widen a river or other natural watercourse for flood control, land drainage, or navigation.Examples: "In England and Wales, this has resulted in significant regional variations (Table 3.4) with the Anglian region returning the highest proportions of embanked and resectioned river channels."; "The second case study illustrates the opportunities for linking data from different monitoring schemes by examining the relationship between two potential stressors: organic pollution and resectioning of the river channel."; "Resectioned rivers are commonly trapezoidal and wider and deeper than natural rivers."

6. (civil engineering, chiefly India) To remove material from the surface of a road in order to achieve a uniform thickness.Examples: "The road from Periwegon to Ananbaw was resectioned and raised in places."; "...a very large quantity of metal obtained by resectioning and cutting down roads to the regulation camber was used in repairs."; "The quantity of asphalt used will vary with the nature of the work. Where no resectioning of the road is necessary, i.e., where the new 2" layer is uniform in thickness on the picked up old surface 0-9cwt, or 100lbs. per 100 sq. ft. will be sufficient, as the binding material in the old surface works up through the new metal."India
