• ### Báo cáo khoa học: "A Generalized-Zero-Preserving Method for Compact Encoding of Concept Lattices"

Constructing an encoding of a concept lattice using short bit vectors allows for efﬁcient computation of join operations on the lattice. Join is the central operation any uniﬁcation-based parser must support. We extend the traditional bit vector encoding, which represents join failure using the zero vector, to count any vector with less than a ﬁxed number of one bits as failure.

The characteristicsof a vector are the magnitude, the orientation, and the sense. The magnitudeof a vector is speci®ed by a positive number and a unit having appropriate dimensions. No unit is stated if the dimensions are those of a pure number. The orientationof a vector is speci®ed by the relationship between the vector and given reference lines and=or planes. Thesenseof a vector is speci®ed by the order of two points on a line parallel to the vector. Orientation and sense together determine the directionof a vector.

• ### Physical Modeling in MATLAB

Most books that use MATLAB are aimed at readers who know how to program. This book is for people who have never programmed before. As a result, the order of presentation is unusual. The book starts with scalar values and works up to vectors and matrices very gradually. This approach is good for beginning programmers, because it is hard to understand composite objects until you understand basic programming semantics.

• ### Eigensystems part 1

An N × N matrix A is said to have an eigenvector x and corresponding eigenvalue λ if A · x = λx (11.0.1) Obviously any multiple of an eigenvector x will also be an eigenvector, but we won’t consider such multiples as being distinct eigenvectors. (The zero vector is not considered to be an eigenvector at all.)

• ### Mechanical Engineer's Handbook

The purpose of this handbook is to present the reader with a teachable text that includes theory and examples. Useful analytical techniques provide the student and the practitioner with powerful tools for mechanical design. This book may also serve as a reference for the designer and as a source book for the researcher.

For n  2, let PG(n, 2) be the finite projective geometry of dimension n over F2, the field of order 2. The elements or points of PG(n, 2) are the one-dimensional vector subspaces of Fn+1 2 ; the lines of PG(n, 2) are the two-dimensional vector subspaces of Fn+1 2 . Each such one-dimensional subspace {0, x} is represented by the non-zero vector x contained in it. For ease of notation, if {e0, e1, . . . , en} is a basis of Fn+1 2 and x is an element of PG(n, 2), then we denote x by a1 . . .as, where x = ea1 +·...

• ### Chapter IX Conductors, Capacitors

1.1 The balance of charges on conductors: In conductors there are charged particles which can be freely move under any small force. Therefore the balance of charges on conductors can be observed under these circumstances:  The electric field equals zero everywhere inside the conductor E = 0 The electric potential is constant inside the conductor V = const  The electric field vector on the surface of conductors direct along the normal of the surface at each point E = En The surface of conductors is equipotential Inside conductors there is no charge.

• ### Electrical Power

If each voltage is connected to a circuit with the same power factor and the three currents return along the same conductor, then the vector sum of the three return currents is zero. Thus instead of three full sized return cables, only one of smaller size is needed. If none of the load is single phase, then the neutral is not needed at all. High voltage supplies are nearly always three phase without a neutral conductor. There is a great economy in distribution costs if the electricity can be supplied in three phases. ...

• ### EXPONENTIAL STABILITY OF DYNAMIC EQUATIONS ON TIME SCALES ALLAN C. PETERSON AND YOUSSEF N. RAFFOUL

EXPONENTIAL STABILITY OF DYNAMIC EQUATIONS ON TIME SCALES ALLAN C. PETERSON AND YOUSSEF N. RAFFOUL Received 6 July 2004 and in revised form 16 December 2004 We investigate the exponential stability of the zero solution to a system of dynamic equations on time scales. We do this by deﬁning appropriate Lyapunov-type functions and then formulate certain inequalities on these functions. Several examples are given. 1. Introduction This paper considers the exponential stability of the zero solution of the ﬁrst-order vector dynamic equation x∆ = f (t,x), t ≥ 0. (1.
