Identifying an Honest ${\rm EXP}^{\rm NP}$ Oracle Among Many

We provide a general framework to remove short advice by formulating the following computational task for a function f : given two oracles at least one of which is honest (i.e. correctly computes f on all inputs) as well as an input, the task is to compute f on the input with the help of the oracles by a probabilistic polynomial-time machine, which we shall call a selector. We characterize the ...

Secuencias de alarmas para detección y diagnóstico de fallos

1  Resumen-En este artículo se habla de las secuencias de las alarmas de una planta industrial y cómo pueden ser utilizadas para detectar y diagnosticar fallos. Este trabajo parte del Gerenciamiento de Alarmas, un tema que busca reducir el número de alarmas desplegadas a los operadores, contribuyendo a la apropiada detección y diagnóstico de fallos. Se muestran algunas técnicas de búsqueda cuy...

Bank ownership, rm value and rm capital structure in Europe*

We investigate the role of banks in the ownership structure of non-…nancial …rms. Distinguishing between banks and other institutional investors as shareholders, we examine the relationship between …nancial institution ownership and the performance of the …rms in which they hold equity. We control explicitly for the capital structure decision of the …rms and the ownership decision of …nancial i...

A RM-Polar Codes

Introduction: Polar codes are a major breakthrough in coding theory [1]. They can achieve Shannon capacity with a simple encoder and a simple successive cancellation (SC) decoder, both with low complexity of the order of ( ) N N log O , where N is the code block size. But for short and moderate lengths, the error rate performance of polar codes with the SC decoding is not as good as LDPC or tur...
