extended abstract 1. introduction security is the most important factor for improving of a city and it’s the initial needs of human. security and developing are mutual relationship that derived from planning and city management. insecurity feeling in the urban area, the activities of human have been eclipsed and economic, cultural, social acts couldn’t be done easily .however security is necess...

The objective of the present review is to analyze and evaluate most used well-performing environmental forest fire danger rating systems indices globally, aiming creation an integrated system for Greece. analysis emphasizes core input parameters that have been associated with (i.e., weather, vegetation, topography, hydrology) computational procedure each index as well categorization output valu...

A new path planning strategy is presented. It is called the local next step method and consists of an iterative process of calculating local targets, moving to them and then recalculating until the goal is reached. It is based on two concepts: the desirability of a direction of motion and the danger associated with that motion. A construct called the local tangent graph which is a tangent graph...

This paper presents an equilibrium model for the demand and supply of liquidity and its impact on asset prices and welfare. We show that when constant market presence is costly, purely idiosyncratic shocks lead to endogenous demand of liquidity and large price deviations from fundamentals. Moreover, market forces fail to lead to efficient supply of liquidity, which calls for potential policy in...

Large-scale fire danger assessment has become increasingly relevant in the past few years, and is usually based on weather information. Still, fuel characteristics also play an important role in fire behavior. This study presents a fire behavior simulation based on a global fuelbed dataset and climatic and topographic information. The simulation was executed using the Fuel Characteristic Classi...
