In this paper, a new 3D-object-recognition method for robotic assembly workcells is presented. The proposed method is focused on two basic concepts , namely active vision and object pre-conditioning. The paper will briefly present the main aspects of the proposed system. 1. The Proposed Recognition Method [l] Herein, it is proposed to model an object using(More)
When k is an integer at least 3, a sequence S of positive integers is called k-GP-free if it contains no nontrivial k-term geometric progressions. Beiglböck, Bergelson, Hind-man and Strauss first studied the existence of a k-GP-free sequence with bounded gaps. In a previous paper the author gave a partial answer to this question by constructing a 6-GP-free(More)
BACKGROUND This study is to explore the key genes and signaling transduction pathways related to the survival time of glioblastoma multiforme (GBM) patients. RESULTS Our results not only showed that mutually explored GBM survival time related genes and signaling transduction pathways are closely related to the GBM, but also demonstrated that our innovated(More)
For a finite abelian group G and a positive integer k, let s k (G) denote the smallest integer ℓ ∈ N such that any sequence S of elements of G of length |S| ≥ ℓ has a zero-sum subsequence with length k. The celebrated Erd˝ os-Ginzburg-Ziv theorem determines s n (C n) = 2n − 1 for cyclic groups C n , while Reiher showed in 2007 that s n (C 2 n) = 4n − 3. In(More)
A novel active-vision system for 3-D object recognition was developed. The vision system combines object pre-marking and active sensing. Therein, an object is modeled by a few of its 2-D perspective (standard) views, each with a corresponding viewing axis defined by a marker placed on the object. The operation of the active-vision system is characterized by(More)
