Entering and Leaving j-Facets
Let S be a set of n points in d-space, no i + 1 points on a common (i − 1)-flat for 1 ≤ i ≤ d. An oriented (d − 1)-simplex spanned by d points in S is called jfacet of S, if there are exactly j points from S on the positive side of its affine hull. We show: (*) For j ≤ n/2 − 2, the total number of (≤ j)-facets (i.e. the number of i-facets with 0 ≤ i ≤ j) in 3-space is maximized in convex positi...
متن کاملPeople Recognition for Entering and Leaving a Video Surveillance Area
The authors proposed a people recognition method for moving people of entering and leaving a video surveillance area employing the spatial-based feature of single-pedestrian image in conjunction with color vector. The spatial-based features are employed for its different location from variant parts of the human body. A histogram-based framework is used to describe the color vector of variant pa...
متن کاملReaction of dialkyl carbonates with alcohols: Defining a scale of the best leaving and entering groups*
A series of dialkyl and methyl alkyl carbonates has been synthesized and their reactivity investigated. The behavior of preferential leaving and entering groups for the newly synthesized carbonates has been accurately investigated. Both experimental and computational studies agreed that the scale of leaving groups follows the trend: PhCH2O –, MeO– ≥ EtO–, CH3(CH2)2O –, CH3(CH2)7O – > (CH3)2CHO ...
متن کاملIn between k -Sets, j -Facets, and i -Faces: (i , j) - Partitions
Let S be a finite set of points in general position in Rd. We call a pair (A,B) of subsets of S an (i, j)-partition of S, if |A| = i, |B| = j and there is an oriented hyperplane h with S∩h = A and with B the set of points from S on the positive side of h. (i, j)-Partitions generalize the notions of k-sets (these are (0, k)-partitions) and j-facets ((d, j)-partitions) of point sets as well as th...
متن کاملEffect of Solvent, Leaving and Entering Ligand on Substitution Rates of Square Planar Complexes of Palladium(II)
Nucleophilic substitution in different non-aqueous solvents at square planar complexes of palladium(II) with l-(2-hydroxyphenyl)-3,5-diphenylformazan ( H 2 F 0 ) according to FoPdX + Y -» FoPdY + X , with X = ammonia and pyridine and Y = triphenylphosphine, thiourea and the thiocyanate ion, obeys the rate law: rate = ki[FoPdX] + k2[FoPdX][Y]. Values of ki and k2 were obtained at 25.0 °C. From m...
