Abstract In this paper we will present the Shell workflow for 4D seismic. This workflow contains several stages: feasibility study, acquisition design, data processing, data interpretation and final feedback loop of the results to the geological and dynamic reservoir models; which in turn are used for field development planning and well ...

Shape-morphing systems can be found in many areas, including smart textiles, autonomous robotics, biomedical devices, drug delivery and tissue engineering. The natural analogues of such systems are exemplified by nastic plant motions, where a variety of organs such as tendrils, bracts, leaves and flowers respond to environmental stimuli (such as ...

4D-DSA and 4D fluoroscopy: preliminary implementation
SPIE Proceedings, 2010We have described methods that allow highly accelerated MRI using under-sampled acquisitions and constrained reconstruction. One is a hybrid acquisition involving the constrained reconstruction of time dependent information obtained from a separate scan of longer duration.

Many cellular processes involve fast movements of weakly labeled cellular structures in all directions, which should be recorded in 3D time-lapse microscopy (4D microscopy). This chapter introduces fast 4D imaging, which is used for sampling the cell's volume by collecting focal planes in time-lapse mode as rapidly as possible, without perturbing the ...

AbstractWe are going to present a survey of techniques using temporal coherence in between frames to render animation sequences with ray tracing. A new method using temporal coherence in the ray space (lightpath of rays) is proposed. The goal of this technique is to factorize intersection and illumination calculations over the frames of the sequence ...

4D Relationships: The Missing Link in 4D Scheduling
Journal of Construction Engineering and Management, 2016AbstractFour-dimensional (4D) schedules have proven successful in planning with their visualization capabilities allowing for coordination and time-space conflict detection. However, when considered in depth, internal aspects of 4D scheduling techniques have not made significant advances from traditional two-dimensional (2D) scheduling. What is missing

Das DFG-Schwerpunktprogramm ‚Das digitale Bild‘ untersucht von einem multiperspektivischen Standpunkt aus die zentrale Rolle, die dem Bild im komplexen Prozess der Digitalisierung des Wissens zukommt. In einem deutschlandweiten Verbund soll dabei eine neue Theorie und Praxis computerbasierter Bildwelten erarbeitet werden.

Extended Abstracts of the 2019 CHI Conference on Human Factors in Computing Systems, 2019
In this video, we showcased "A-line", a 4D printing system for designing and fabricating morphing three-dimensional shapes out of simple linear elements. A-line integrates a method of bending angle control in up to eight directions for one printed line segment, using a single type of thermoplastic material.

ACM SIGGRAPH 2008 new tech demos, 2008
This work originated a unique idea of imaginary multidimensional fish by integrating CG and real sculpture. Making an CG animation which includes a tentacle-like fish, and a Lenticular of it, then transform it in a real sculpture with vivid color. There happen an intersection between each dimension as hyper, 4D sculpture.
