OBJECTIVES To examine the effect on estimated levels of health conditions produced from large-scale surveys, when either list-wise respondent deletion or standard demographic item-level imputation is employed. To assess the degree to which further bias reduction results from the inclusion of correlated ancillary variables in the item imputation process. DESIGN Large cross-sectional (US level)...

in order to understand the impact of layer-wise scanning direction in the selective laser sintering process, test coupons were manufactured for mechanical testing from duraform™ polyamide powder. the effects of laser energy density, varying between 0.003 and 0.024 j/mm 2 were examined in test specimens rotated 90º through the z axis. sls machines do not always facilitate ‘cross-hatching’ of lay...

AbstractCrowd counting research has made significant advancements in real-world applications, but it remains a formidable challenge cross-modal settings. Most existing methods rely solely on the optical features of RGB images, ignoring feasibility other modalities such as thermal and depth images. The inherently differences between different diversity design choices for model architectures make...
