progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

honeypot is a security device the value of which lies mainly in discovering and inspecting, being attacked and being at risk. most of the present honeypots are configured and installed on the network statically. in some cases considerations have been made on dynamic configuration of honeypots at the time of installation but still no study have been carried out on how to instantaneously change t...

abstract background: various types of foot orthoses are prescribed for people with flatfoot. it has been reported that orthoses not only improve the biomechanics of the lower limb, but also have good effects on some balance parameters in these subjects. it is hypothesized that the latter effect is dependent on the rigidity of the orthoses. the aim of this study was to evaluate and compare the e...

The visualization of SAR images involves the mapping of high dynamic range amplitude values to gray levels for lower dynamic range display devices. This dynamic range reduction process determines the visibility of details in the displayed result. It is therefore an important part of SAR visualization systems. The problem of dynamic range reduction for SAR images is related to the tone mapping p...

Tone mapping of high dynamic range (HDR) images for realistic display is a commonly studied. However, scientific visualization of HDR image for analysis of scene luminance has much less attention. In this paper, we have presented and implemented a simple approach for the reproduction and visualization of the color information in HDR images. We attempt several simple color visualizing functions,...

This paper offers an overview of the challenges and opportunities presented by high dynamic range (HDR) imaging. We examine the length of the imaging pipeline, from creation and storage through image editing and viewing, and discuss how each stage is affected by a move to HDR.
