The point cloud is the basis for 3D object surface reconstruction. An incomplete significantly reduces accuracy of downstream work such as reconstruction and recognition. Therefore, point-cloud repair indispensable work. However, original shape difficult to restore due uncertainty position new filling point. Considering advantages convex set in dealing with problems, we propose a method via tha...

The main goal of the bilingual and monolingual participation of the MIRACLE team in CLEF 2004 was to test the effect of combination approaches on information retrieval. The starting point was a set of basic components: stemming, transformation, filtering, generation of n-grams, weighting and relevance feedback. Some of these basic components were used in different combinations and order of appl...

This paper’s aim is to present a tuning approach for full Two-Degree-of-Freedom (2-DoF) PI and PID controllers for First-Order-Plus-Dead-Time (FOPDT) and Second-OrderPlus-Dead-Time (SOPDT) controlled processes. The tuning relations provide the value of the typical parameters for a PID controller plus the set-point weighting factor, being these relations driven by just one single design paramete...

We introduce Coherent Point Drift (CPD), a novel probabilistic method for nonrigid registration of point sets. The registration is treated as a Maximum Likelihood (ML) estimation problem with motion coherence constraint over the velocity field such that one point set moves coherently to align with the second set. We formulate the motion coherence constraint and derive a solution of regularized ...

The high school grade point average (GPA) is often adjusted to account for nominal indicators of course rigor, such as “honors” or “Advanced Placement.” Adjusted GPAs—also known as weighted GPAs—are used widely for computing students’ rank in class and in the college admission process. Despite the high stakes attached to GPA, weighting policies vary considerably across states and schools, with ...

This study introduces a new multi-criteria group decision-making model in organ transplant transportation networks under uncertain situations. A combined weighting approach is presented to obtain expert weights with various kinds of opinions by integrating similarity measure and subjective judgments experts. Also, the CRITIC given criteria weights. Finally, novel integrated ranking proposed cal...

The convergent validity of ®ve multiattribute weighting methods is studied in an Internet experiment. This is the ®rst experiment where the subjects created the alternatives and attributes themselves. Each subject used ®ve methods to assess attribute weights ± one version of the analytic hierarchy process (AHP), direct point allocation, simple multiattribute rating technique (SMART), swing weig...
