Ambulance response time to emergency calls is a key indicator of health system's efficiency although its impact on not precisely known. This causal relation identified by exploiting rainfall at the ambulance run as shock responsiveness. The elasticity likelihood severe cardiovascular condition with respect 0.9 and that death before reaching hospital 5. Finally, economic value quantified, it sho...

Given a set oft raining examples, determining the appropriate number of free parameters is a challenging problem. Constructive learning algorithms attempt to solve this problem automatically by adding hidden units, and therefore free parameters, during learning. We explore an alternative class of algorithms-called metamorphosis algorithms-in which the number of units is fixed, but the number of...

This paper provides a physically based model to animate water. A disturbance model is proposed to simulate various kinds of waves. We use a powerful solver called Finite Volume Method to solve the water uid equation and give various kinds of disturbance to the solutions according to di erent disturbance sources such as wind and rain droplets. In this way, we can nicely simulate the movement of ...

Iran is located in dry zone of mid-latitude in which the mean rainfall is 250 mm and it has dramatic tempo-spatial changes. Rainfalls with short persistency are of characteristics of dry regions and it is also tangible in Iran. However, Iran’s rainfalls persistency ranges from 1 to 45 days and have dramatic tempo-spatial changes, but the maximum amount and days of rainfalls are supplied by rain...

The importance of weather for tourism is now widely recognized. However, no research has so far addressed weather events from retrospective viewpoints, and, in particular, the role of “extreme” events in longer-term holiday memories. To better understand the character of ex post weather experiences and their importance in destination image perceptions and future travel planning behavior, this e...
