Ontology Driven Analysis of Spatio-temporal Phenomena, Aimed At Spatial Planning And Environmental Forecasting

Uncertainty Analysis of Magnitude, Temporal and Spatial Distribution of Precipitation in Flood Forecasting

  عدم قطعیت در بارش پیش بینی شده، یک منبع اصلی عدم قطعیت در پیش بینی بهنگام سیل می باشد. عدم قطعیت بارش از عدم قطعیت در مقدار بارش، توزیع زمانی و توزیع مکانی بارش تشکیل می شود. در این تحقیق به منظور پخش عدم قطعیت بارش در مدل پیش بینی سیل HEC-1 ، روش گسسته سازی زمانی در چهارچوب اصل بسط تئوری فازی و در ترکیب با الگوریتم ژنتیک نرمال بکار برده می شود. عدم قطعیت به علت توزیع زمانی ناشناخته بارش با ت...

Spatio-Temporal Visual Ontology

In order to semantically describe and structure the visual content of images and video scenes captured by cameras with arbitrary resolution and unknown calibration properties, we propose a spatio-temporal visual ontology (STVO). In Artificial Intelligence (AI), an ontology is an explicit specification of a conceptualization [4] and thus consists of a set of semantic concepts as well as the rela...

Planning for Protected Areas Using Spatial and Temporal Metrics

SMT Spatio-Temporal Planning

Solving real planning problems requires to consider spatial and temporal information. Indeed, to be solved more efficiently many real world problems need to take the action duration, the instants of effects occurrences, the instants of requiring preconditions. . . and the space in which the mission is accomplished by defining the different actions zones and know the path between these zones int...

Visual Analysis of Spatio-Temporal Data: Applications in Weather Forecasting

Weather conditions affect multiple aspects of human life such as economy, safety, security, and social activities. For this reason, weather forecast plays a major role in society. Currently weather forecasts are based on Numerical Weather Prediction (NWP) models that generate a representation of the atmospheric flow. Interactive visualization of geo-spatial data has been widely used in order to...
