We describe a graph-based global registration method for creating 2D mosaic images. When multi-frames overlap in space, global registration is necessary to minimize the accumulated registration errors. We use a graph to represent the temporal and spatial connectivity and show that global registration can be obtained through the search for an optimal path in the constructed graph. The definition...

The paper discusses discrete frames as an attractive semantics for modal logic. We study questions of completeness, persistence, duality and definability. Notions of completeness, strong global completeness and complexity of dual varieties coincide for discrete frames; moreover, they are equivalent to conservativity of minimal hybrid extensions. The paper also provides some criteria of di-persi...

In this paper, a two-stage method for damage detection and estimation in tall shear frames is presented. This method is based on the first mode shape of a shear frame. We demonstrate that the first mode shape slope is very sensitive to the story stiffness. Thus, at the first stage, by using the grey system theory on the first mode shape slope, damage locations are identified in shear frames. Da...

A number of individuals and organizations have considerable influence over the selection of global health priorities and strategies. For some that influence derives from control over financial resources. For others it comes from expertise and claims to moral authority—what can be termed, respectively, epistemic and normative power. In contrast to financial power, we commonly take for granted th...

the commentator suggests that it is necessary to extend the classical connotation of  global city which focuses much on the functions of controlling global capital and production. global city should also include the dimensions of the leading role and capacity on health improvements and well-being promotion. the commentator agrees with authors’ assessments about shanghai’s substantial progress o...

since the mid-19 th century, human activities have increased greenhouse gases such as carbon dioxide, methane, and nitrous oxide in the earth's atmosphere that resulted in increased average temperature. the effects of rising temperature include soil degradation, loss of productivity of agricultural land, desertification, loss of biodiversity, degradation of ecosystems, reduced fresh-water resou...

background vertically oriented global health initiatives (ghis) addressing the hiv/aids epidemic, including the president’s emergency plan for aids relief (pepfar), have successfully contributed to reducing hiv/aids related morbidity and mortality. however, there is still debate about whether these disease-specific programs have improved or harmed health systems overall, especially with respect...

Distributed Video Coding (DVC) is a recently proposed paradigm in video communication, which fits well emerging applications such as wireless video surveillance, multimedia sensor networks, wireless PC cameras, and mobile cameras phones. These applications require a low complexity encoding, while possibly affording a high complexity decoding. DVC presents several advantages: First, the complexi...
