This paper introduces a methodology for the synthesis of nonlinear finite-dimensional output feedback controllers for systems of quasi-linear parabolic partial Ž . differential equations PDEs , for which the eigenspectrum of the spatial differential operator can be partitioned into a finite-dimensional slow one and an infinitedimensional stable fast complement. Combination of Galerkin’s method ...

Digital materials such as the ones shown by Objet’s Connex family demonstrate that a new material with desired characteristics can be achieved by combining two different base materials with various concentrations and structures. We investigate the feasibility of using additive manufacturing processes based on digital mask projection in the fabrication of such digital materials. A multi-material...

In software testing, it is often desirable to find test inputs that exercise specific program features. To find these inputs by hand is extremely time-consuming, especially when the software is complex. Therefore, many attempts have been made to automate the process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired softwar...

In the product design area, the major concern is how to obtain the desired product requirements in a physically possible and economical process way. A reverse engineering based approach is proposed here for the generation of possible process alternatives applied to crystallization area, in order to obtain desired crystal features. The called umbrella-like approach integrates thermodynamics and ...

Let A be a. matrix of m rows and n columns and let the entries of A be the integers 0 and 1. We call such a matrix a (0, 1) -matrix of size m by n. The 2 (0, 1)-matrices of size m by n play a fundamental role in a wide variety of combinatorial investigations. One of the chief reasons for this is the following. Let X be a set of n elements Xi, X2, • • • , xn and let Xi, X2, • • • , Xm be m subse...

In the last two decades institutional economics of development has been enriched by historical and, more recently, quantitative analysis of the effects of the quality of institutions on the pace and pattern of economic development. Following the leadership of Douglass North, this literature has shown how important secure property rights are in encouraging investment and innovations, allowing fo...
