We demonstrate image processing algorithms that achieve the distortion-corrected projection on surfaces with horizontal discontinuity, with casually placed camera and projector. We focus on three cases of perspective-corrected projection: single projection on flat surface, single projection on wall corner, multiple projections on flat surface. Image pre-warping is used to achieve screen geometr...

The aim of this research was to investigate how the decentralization of counseling and rapid testing for HIV (Human Immunodeficiency Virus), syphilis, and hepatitis B and C have been implemented in the city of Porto Alegre, Brazil, using matrix support with Primary Health Care teams. It is a qualitative study, in which eight matrix supporters were interviewed. Positive aspects include training ...

Instead of ‘researching’ for perfected (yet rejected) solutions, IMAG-DLO stresses the need for a farmer participatory approach towards: local development of less perfect, yet accepted practical and low-cost technologies; based on simple and durable equipment designs suitable for local manufacture.

hydraulic fracturing (hf), as a stimulation technique in petroleum engineering, has made possible the oil production from reservoirs with very low permeability. the combination of horizontal drilling and multiple hf with various perforation angles has been widely used to stimulate oil reservoirs for economical productions. despite the wide use of hf, there are still ambiguous aspects that requi...

Twelve cases of endocardial cushion defect were studied before and after operation with ultrasono-cardiotomography (tomography) cross-sectional echocardiography, two-dimensional echocardiography, B-scan echocardiography) and M-mode scan along a horizontal section of the heart. For comparison, 20 healthy subjects, 18 cases of mitral valvular disease, 4 cases of congestive cardiomyopathy, 1 case ...

Are democratic crises also human crises? While the determinants of erosion democracy have been extensively scrutinised in literature, their public policy consequences remain relatively unexplored. In a novel attempt to navigate this uncharted terrain, we analyse effect autocratization on health outcomes. We conceptualise as relative decline ‘vertical’ and ‘horizontal’ accountability. ‘Vertical ...

We present high resolution UVES+VLT spectroscopic observations of 61 stars in the extended blue horizontal branches of the Galactic globular clusters NGC 1904 (M79), NGC 2808, NGC 6093 (M80), and NGC 7078 M15). Our data reveal for the first time the presence in NGC 1904 of a sizable population of fast (vsini ≥ 20 km/s) horizontal branch (HB) rotators, confined to the cool end of the EHB, simila...
