Diese Arbeit behandelt die Klassifizierung des Himmels in Bergbildern. Zu Beginn wird ein Verfahren zur Abschätzung des Himmels in einem Bild vorgestellt. Im Anschluss folgt die Vorstellung eines auf FloodFill-basierenden Klassifikators. Abschließend werden die Ergebnisse verschiedener Klassifikatoren vorgestellt. Eine Klassifizierung des Himmels dient der Vorbereitung für eine spätere Segmenti...

On 12 May 2008, the 8.0-magnitude Wenchuan earthquake occurred in Sichuan Province, China, triggering thousands of landslides, debris flows, and barrier lakes, leading to a substantial loss of life and damage to the local environment and infrastructure. This study aimed to monitor the status of geologic hazards and vegetation recovery in a post-earthquake disaster area using high-resolution aer...

background in the past 10 years, 13 fatal earthquakes have occurred in iran and led to death of 30,000 people whom most of them were killed in the earlier hours of the disaster. disaster medical assistance teams are groups of trained medical and non-medical personnel with various combinations that on the optimal conditions are deployed just within 8 hours of notification and are able to work se...

The Yumu Shan is located at the northern margin of Tibetan Plateau in northwest China. It characterized by development several northeastward-protruding arcuate geomorphic bulge belts on its north slope. These are distributed along Wutongquan spring, ancient Camel City, and Xiaogengzi area, south to Gaotai City Hexi Corridor. In this study, our detailed field mapping structural analysis reveal n...

flood risk zonation is necessary to control and predict the amplitude of flood damage.the purpose of this research is to evaluate the rate of flood risk vulnerability and the flood damage assessment in tabriz. specific variables of this study are land use , population density , river beds , slope classes residential density , cn coefficient , runoff coefficient , open spaces and old buildings.m...

16. Abstract This study evaluated the resilience of highway bridges under the multihazard scenario of earthquake in the presence of flood-induced scour. To mitigate losses incurred from bridge damage during extreme events, bridge retrofit strategies are selected such that the retrofit not only enhances bridge performance, but also improves resilience of the system consisting of these bridges. T...

1. introduction iran is one of the most disaster-prone countries in the world. as the statistics show, 31 cases out of 40 types of natural disasters occurring in the world happens in iran. such natural disasters in the country have placed iran on the list of top ten countries of the world in terms of natural disasters in which the incidence and frequency of natural disasters such as earthquake,...

flood is considered as a major threat among natural disasters in the world. this case becomes more important and has a higher risk in urban areas due to the existence of important uses. therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. considering the development in iran has been carried out in high risk...
