With reference to the vehicular traffic scenario depicted in Figure 1, we define as i the vehicle whose behavior is currently under investigation. At a given time instant t, such vehicle is at a position xi(t), and travels with a speed vi(t), meaning that its instantaneous acceleration can be expressed as dvi(t) dt . Indexes i − 1 and i + 1 identify the back and front vehicles with respect to i...

The Integrated Enterprise The Integrated Enterprise The Integrated Enterprise The Integrated Enterprise The Integrated Enterprise Getzner Textil AG employs a workforce of 800 employees in the manufacture of high fashion shirting materials. Between 1989 and 1991 Getzner redesigned all its business processes. Using an integrated software package, the textile company was able to improve the speed ...

parent, generally their mother. Divorce rates rose dramatically in the 1960s and 1970s and have remained high. At the same time, more individuals are waiting to older ages to marry, or are not marrying at all, thus increasing the period during which women are at risk of a nonmarital birth. By the late 1990s, 26 percent of white children, 41 percent of Hispanic children, and 69 percent of black ...

We show that Szepietowski’s system of generators [8] for the mapping class group of the non-orientable surface is the minimal generating set by Dehn twists and Y -homemorphisms. Let Ng be a non-orientable surface which is a connected sum of g projective planes. We assume that g ≥ 4. Let M(Ng) be the group of isotopy class of homeomorphisms over Ng, i.e, the mapping class group of Ng. We introdu...

This paper proposes a novel algorithm for the automatic coarse classification of iris images using a box-counting method to estimate the fractal dimensions of the iris. First, the iris image is segmented into sixteen blocks, eight belonging to an upper group and eight to a lower group. We then calculate the fractal dimension value of these image blocks and take the mean value of the fractal dim...

Despite a lack of consensus on the nature of Computing Research Methods (CRM), a growing number of programs are exploring models and content for CRM courses. This report is one step in a participatory design process to develop a general framework for thinking about and teaching CRM. We introduce a novel sense-making structure for teaching CRM. That structure consists of a road map to the CRM li...

Introduction Having applications to Form recognition in mind, we want to be able to compare shapes of surfaces in R3 in a way that does not depend on parameterizations. To accomplish such so-called gauge invariance, we defined a metric on the space of parameterized surfaces that is degenerate in the direction of reparameterization. 1 What are the surfaces under consideration? The surfaces we wi...

The purpose of this paper is to establish some properties that appear in a square cut by two rays at 45 degrees passing through a vertex of the square. Elementary proofs and other interesting comments are provided. 1. A simple problem and a reformulation The starting point of this work is the following problem from [3], partially discussed in [4]. 1 Proposition 1. Two points M and N on the hypo...

Let us consider the problem of sequential prediction of categorical data. Let D = {0, 1, . . . , d−1} denote the set of possible outcomes with d ≥ 2. Let x1, x2, . . . be an infinite sequence with values in D. Let Y1, Y2, . . . denote the sequence of predictions. This is a random sequence with values in D. Yn+1 predicts xn+1 and may depend on the first n outcomes x1, x2, . . . , xn, Y1, Y2, . ....

Background : Modularity and hierarchy Minsu Kang September 18, 2000 1 Architectural Hierarchy Instead of describing the entire system in a at manner, it is more manageable to divide it into subsystems, design each of them and compile them into one big system, especially when the system is not of trivial size. Instantiation In the previous lecture, we designed a state machine for a process in \t...
