The paper deals with the prediction of the 3D surface topography obtained in 5-axis milling in function of the machining conditions. For this purpose, a simulation model for the prediction of machined surface patterns is developed based on the well-known N-buffer method. As in sculptured surface machining the feed rates locally vary, the proposed model can be coupled to a feed rate prediction m...

We present 3D optical topography images reconstructed from data obtained previously while infants observed videos of adults making natural movements of their eyes and hands. The optical topography probe was placed over the temporal cortex, which in adults is responsible for cognitive processing of similar stimuli. Increases in oxyhaemoglobin were measured and reconstructed using a multispectral...

Topography mapping is an important and general strategy for the nervous system to encode the locations of sensory stimuli. It has been difficult to analyze the relative spatial position between adjacent neurons in the same nervous system because of complex fine branches of axon terminals, especially at single-cell resolution. This paper describes an automatic image analysis tool QTIP (Quantifie...

The importance of 3-dimensional (3D) topography in influencing neural stem and progenitor cell (NPC) phenotype is widely acknowledged yet challenging to study. When dissociated from embryonic or post-natal brain, single NPCs will proliferate in suspension to form neurospheres. Daughter cells within these cultures spontaneously adopt distinct developmental lineages (neurons, oligodendrocytes, an...

The objective of this new project is to investigate the generation of complex seismic waves by explosions in media with realistic three-dimensional (3D) heterogeneity, including topography. To do this, we use information on subsurface heterogeneity from nuclear test sites to develop 3D models that have the characteristics of the emplacement media for actual nuclear tests. We then run calculatio...

In this paper, we present a 3D topography simulator, socalled 3D-SURFILER(SURface proFILER), to model a complicated 3D structure on the substrate for gigabit DRAMs. The 3D-SURFILER comprises a deposition and etching simulator employing a cell advancing scheme and a parallel computational numerical engine. An MIM (MetalInsulator-Metal) stacked capacitor [1] has been chosen to verify the validity...

This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D) model. Images of a double arch masonry dam upstream face are acquired from drone survey and used to build the 3D model of the dam for vulnerabil...

This paper presents an experimental research focusing on the view of first year students. The aim is to check the quality of implementing 3D models integrated in the curriculum. We search to determine students ́ preference between the various means facilitated in order to understand the given subject. Students have been respondents to prove the hypotheses about the 3D models used in class to exp...
