EXPRESSION AND ORGANIZATION OF GEOGRAPHIC SPATIAL RELATIONS BASED ON TOPIC MAPS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Spatial Relation is one of the important components of Geographical Information Science and Spatial Database. There have been lots of researches on Spatial Relation and many different spatial relations have been proposed.

Spatial attention and the apprehension of spatial relations. [PDF]
Journal of Experimental Psychology: Human Perception and Performance, 1994 Seven experiments examined the role of spatial attention in apprehending spatial relations above, below, left, and right. In Experiment 1, visual search was difficult when targets differed from distractors only in the spatial relation between their elements. Reaction time increased linearly with display size with a slope greater than 60 ms/item.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Homotopy on spatial graphs and the Sato-Levine invariant
, 2007 Edge-homotopy and vertex-homotopy are equivalence relations on spatial graphs which are generalizations of Milnor's link-homotopy. We introduce some edge (resp. vertex)-homotopy invariants of spatial graphs by applying the Sato-Levine invariant for the 2-

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

On Certain Spatial Patterns in Perm Region Microtoponymy
Научный диалог, 2019 The relevance of the work is determined by the analysis of microtoponymy of the Perm Region, which is poorly studied. The language models of spatial relations expression on the material of Perm toponymy are considered for the first time.

Deriving ambiguous spatial relations [PDF]
1993 4th Annual Conference on AI, Simulation and Planning in High Autonomy Systems, 2002 Qualitative and relational representations of space offer a new and powerful approach to reasoning. This type of approach introduces ambiguity where there would be none in quantitative methodologies. Mechanisms for coping with ambiguity and examples of using these mechanisms for reasoning about space are given here. >

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Mining topological relations from the web [PDF]
, 2008 Topological relations between geographic regions are of interest in many applications. When the exact boundaries of regions are not available, such relations can be established by analysing natural language information from web documents.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
