This paper suggests applying tools of analysis that had been used previously in the …eld of occupational segregation and horizontal inequity measurement to the study of intergenerational social immobility. The paper introduces the concept of “social immobility curve”and two indices of social immobility are proposed that are extensions of the Theil and Gini indices of inequality. The paper stres...

We survey two recent signature constructions that support signature aggregation: Given n signatures on n distinct messages from n distinct users, it is possible to aggregate all these signatures into a single signature. Aggregate signatures are useful for reducing the size of certificate chains (by aggregating all signatures in the chain) and for reducing message size in secure routing protocol...

This paper considers the relaxed Peaceman-Rachford (PR) splitting method for finding an approximate solution of a monotone inclusion whose underlying operator consists of the sum of two maximal strongly monotone operators. Using general results obtained in the setting of a non-Euclidean hybrid proximal extragradient framework, convergence of the iterates, as well as pointwise and ergodic conver...

In this paper we describe a Parallel Performance Estimator suitable for the comparative evaluation of parallel algorithms. The Esti-mator is designed for SPMD programs written in either C or FORTRAN. Simulation is used to produce estimates of execution times for varying numbers of processors and to analyse the communication overheads. Results from the estimator are compared with actual results ...

A major problem in using iterative number generators of the form xi = f(xi−1) is that they can enter unexpectedly short cycles. This is hard to analyze when the generator is designed, hard to detect in real time when the generator is used, and can have devastating cryptanalytic implications. In this paper we define a measure of security, called sequence diversity, which generalizes the notion o...

The alternating direction method of Peaceman and Rachford is considered for elliptic difference schemes of second order and with two independent variables. An earlier result of the author's on the rapid convergence of multi-parameter noncommutative problems is described and a connection is established between that result and theorems on optimal scaling of band matrices. Simple algorithms to dec...

We present a multilevel high order ADI method for separable generalized Helmholtz equations. The discretization method we use is a onedimensional fourth order compact finite difference applied to each directional component of the Laplace operator, resulting in a discrete system efficiently solvable by ADI methods. We apply this high order difference scheme to all levels of grids, and then start...

A repetition free Longest Common Subsequence (LCS) of two sequences x and y is an LCS of x and y where each symbol may appear at most once. Let R denote the length of a repetition free LCS of two sequences of n symbols each one chosen randomly, uniformly, and independently over a k-ary alphabet. We study the asymptotic, in n and k, behavior of R and establish that there are three distinct regim...

ReApp is a mobile, multiplayer game aimed at training people in emotional regulation, specifically in cognitive reappraisal (CR). The game was produced as part of an interdisciplinary research between a group of researchers from the Baruch Ivcher School of Psychology at IDC Prof. Eran Halperin, Lihi Harel, and researchers from the Game Design Program at Shenkar College for Engineering and Desig...
