We have developed a new method for transforming images with per-pixel displacements into textures that have correct parallax when texture-mapped, in the usual way, onto polygons. Our new method results from factoring the 3-D image-warping equations of McMillan and Bishop into a prewarp followed by standard texture mapping. The pre-warp handles only the parallax effects resulting from the direct...

Supply Chain Management (SCM) is seldom more difficult than during disaster relief efforts. As these supply chains quickly form, the lack of information flow presents a major hindrance to coordinating the flow of resources necessary for disaster relief efforts. This paper identifies impediments to the flow of information through supply chains following large scale and catastrophic disasters. Gi...

Purpose The stakeholders are now demanding more visibility and role clarity in the emergency supply chain to improve collaborative efforts. Using a contingent resource-based view (C-RBV), author studies crisis leadership as complementary organizational resource for successful adoption of digital technologies (DTs) chain. further examined relationships between DTs on information collaboration un...

Relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. Placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. Relief wells are often used in combina...

BACKGROUND Pain is common in older people, particularly those in residential aged care facilities (RACF) and those with dementia. However, despite 20 years of discourse on pain and dementia, pain is still undetected or misinterpreted in people with dementia in residential aged care facilities, particularly those with communication difficulties. METHODS A topical survey typology with semistruc...

shown with this specimen demonstrating asymmetry of the vertebral arteries. The circle-of-Willis in this specimen has diffuse patches of atheroma in its walls. The final section of this tape is on the external ear, the tympanic membrane and auditory ossicles. Summary These five tapes are a magnificent learning aid for both the student and clinician. This reviewer has prepared a small specimen f...
