Perhaps the most important goal of any engineering program that seeks to gather employer and alumni feedback is to get a clear picture of the work performance strengths and weaknesses of an institution's graduates. A basic problem in such assessment concerns the variety of data sources and types of feedback used. Different data sources have different bias characteristics, so that depending on o...

In the framework of the study of extragalactic radio sources, we will focus on the importance of the spatial resolution at different wavelengths, and of the combination of observations at different frequency bands. In particular, a substantial step forward in this field is now provided by the new generation X-ray telescopes which are able to image radio sources in between 0.1–10 keV with a spat...

A new generalised approach for multiple correlated sources over a wiretap network is investigated. A basic model consisting of two correlated sources where each produce a component of the common information is initially investigated. There are several cases that consider wiretapped syndromes on the transmission links and based on these cases a new quantity, the information leakage at the source...

We consider the problem of bounding the loss rate of the aggregation of independent on-off sources in a bufferless model by the loss rate resulting from the aggregation of i.i.d. on-off sources. This is done through a unified framework based on the interplay of well-known results from the theory of variability orderings with the concept of majorization ordering. In particular, we use a basic co...

The basic polarization phenomenon for i.i.d. sources is extended to a framework allowing dependencies within and between multiple sources. In particular, it is shown that taking the polar transform of a random matrix with i.i.d. columns of arbitrary (correlated) distribution allows to extract the randomness and dependencies. This result is then used to develop polar coding schemes (having low c...

For México, the sixties became a decade of social movements, modernization attempts, and a golden age for the middle class. Yet, historians often overlook the sixties because it is seen merely as a period of economic growth. However, many sources that are seldom analyzed portray a different history of México. This project utilizes corridos, or narrative ballads, as primary sources to depict a h...

In this paper we present a number of techniques that can be at the basis of a practical integration tool for multidimensional databases. We start by addressing the basic issue of matching heterogeneous dimensions and provide a number of general properties that a dimension matching should fulfill. We then propose two different approaches to the problem of integration that try to enforce matching...

We present results from in-flight calibration of the High Energy Transmission Grating Spectrometer (HETGS) on the Chandra X-ray Observatory. Basic grating assembly parameters such as orientation and average grating period were measured using emission line sources. These sources were also used to determine the locations of individual CCDs within the flight detector. The line response function (L...
