Detection of medical information such as osteophyte on spine xray images is an important task for spine x-ray image retrieval. Curve matching can be used to match partial shapes for image retrieval. Using a curve segment that contains osteophyte information as the query for matching provides more accurate retrieval information than whole shape matching. This paper presents curve matching method...

Geometric matching in general is a di cult unsolved problem in computer vision. Fortunately, in many practical applications, some a priori knowledge exists which considerably simpli es the problem. In visual navigation, for example, the motion between successive positions is usually either small or approximately known, but a more precise registration is required for environment modeling. The al...

This paper presents an analytical model to describe the transient fluid flow a horizontal fracture in frac-packed vertical wells. A physical is first established where located middle of cylindrical reservoir. The pressure distribution then derived concerning time and distance wellbore. assumes homogeneous isotropic reservoir Darcy's law applies single-phase flow, radial with radius much greater...

We introduce matchmakereft, a fully automated tool to compute the tree-level and one-loop matching of arbitrary models onto effective theories. Matchmakereft performs an off-shell matching, using diagrammatic methods background field method (BFM) when gauge theories are involved. The large redundancy inherent together with explicit invariance offers significant number non-trivial checks results...
