Massachusetts Immigrants by the Numbers: Demographic Characteristics and Economic Footprint

Massachusetts Immigrants by the Numbers: Demographic Characteristics and Economic Footprint is the first ILC-commissioned study that looks across the contributions that immigrants make in all their roles as members of the Massachusetts community. It is a groundbreaking study that provides basic and new data about Massachusetts immigrants including pioneering compilations of data about immigrants as tax payers and consumers. This one report provides a comprehensive picture of immigrants' characteristics and their contributions as well as challenges to their effective integration into the economic and social life of the state. The ILC hopes that this study will reinforce its continuing mission to raise the visibility of immigrants as assets to America

Lensless Imaging by Compressive Sensing

In this paper, we propose a lensless compressive imaging architecture. The architecture consists of two components, an aperture assembly and a sensor. No lens is used. The aperture assembly consists of a two dimensional array of aperture elements. The transmittance of each aperture element is independently controllable. The sensor is a single detection element. A compressive sensing matrix is implemented by adjusting the transmittance of the individual aperture elements according to the values of the sensing matrix. The proposed architecture is simple and reliable because no lens is used. The architecture can be used for capturing images of visible and other spectra such as infrared, or millimeter waves, in surveillance applications for detecting anomalies or extracting features such as speed of moving objects. Multiple sensors may be used with a single aperture assembly to capture multi-view images simultaneously. A prototype was built by using a LCD panel and a photoelectric sensor for capturing images of visible spectrum.Comment: Accepted ICIP 2013. 5 Pages, 7 Figures. arXiv admin note: substantial text overlap with arXiv:1302.178
