A New Method For Three Dimensional Cubic Bezier Surface Reconstruction Based On Matching The Surface Framework [PDF]
Engineering and Technology Journal, 2010 Numerous efforts have been directed to convert the physical model ( in-handmodel) to a computer model. This work is dedicated for the cubic Bezier surfacereconstruction based on finding the positions of the sixteen control points that form thesurface of ...

Hepatology Communications, EarlyView., 2022 Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.

Exponentially Increasing Incidences of Cutaneous Malignant Melanoma in Europe Correlate with Low Personal Annual UV Doses and Suggests 2 Major Risk Factors [PDF]
, 2015 For several decades the incidence of cutaneous malignant melanoma (CMM) steadily increased in fair-skinned, indoor-working people around the world. Scientists think poor tanning ability resulting in sunburns initiate CMM, but they do not understand why ...

IET Networks, EarlyView., 2022 Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Estimation of minimum volume of bounding box for geometrical metrology
International Journal of Metrology and Quality Engineering, 2020 This paper presents algorithms for estimating the minimum volume bounding box based on a three-dimensional point set measured by a coordinate measuring machine. A new algorithm, which calculates the minimum volume with high accuracy and reduced number of
