The process of convening arbitrary real numbers bito a floating poini format is formalized as a mapping of the reals into a specified subset of real numbers. The structure of this subset, the set of n significant digit base ß floating point numbers, is analyzed and properties of conversion mapp.ngs are determined. For a restricted conversion mapping of the n significant digit base ^numbers to t...

A new approach for measuring the INL and DNL of an A/D Converter that uses histogram information is introduced. Unlike most existing algorithms, this method does not require the generation of accurate input signals so offers potential for use in a Built-in Self-Test (BIST) environment. Multiple inputs are presented to the device under test and the histograms obtained at the output are analyzed ...

For a computable field F , the splitting set SF of F is the set of polynomials with coefficients in F which factor over F , and the root set RF of F is the set of polynomials with coefficients in F which have a root in F . Results of Frohlich and Shepherdson in [3] imply that for a computable field F , the splitting set SF and the root set RF are Turing-equivalent. Much more recently, in [6], M...

The measurement of static test parameters for an analog-todigital converter (ADC) requires a large volume of test data, especially for a high-resolution ADC. This paper proposes a reduced-code test method for pipelined ADCs that does not compromise test accuracy. The proposed method calculates fault information at each stage by using sub-histograms. The simulation results based on 12-bit pipeli...

In this paper, we analyze the distribution of the eigenvalues of glued tridiagonal matrices. Such matrices provide a useful class of test matrix because, despite being unreduced, a glued matrix can have some eigenvalues agreeing to hundreds of decimal places. A glued matrix can be obtained from a direct sum of p copies of an unreduced symmetric tridiagonal matrix T by modifying the junctions, i...

2 The memory entitled " Theoretical study of the fluorinating power of SF 6 to vanadocene " corresponds to the work carried out by Luis Martínez Suárez to obtain the Official Master Title on Computational and Theoretical Chemistry, done in the Departament de Química Física of the Universitat de Barcelona and supervised by Dr. Juan J. Novoa Vide, whom certifies and gives his consent to its prese...

Based on the unique traits of biological motion perception, the existence of a “life detector”, a special sensitivity to perceiving motion patterns typical for animals, seems to be plausible (Johnson, 2006). Showing motion displays upsidedown or with changes in global structure is known to disturb processing in different ways, but not much is known yet about how inversion affects attention and ...

For a computable field F , the splitting set SF of F is the set of polynomials in F [X] which factor over F , and the root set RF of F is the set of polynomials in F [X] which have a root in F . Results of Fröhlich and Shepherdson in [3] imply that for a computable field F , the splitting set SF and the root set RF are Turing-equivalent. Much more recently, in [5], Miller showed that for algebr...
