Susceptibility Zoning of Dust Source Areas by Data Mining Methods over Khorasan Razavi Province

Extended abstract Introduction Dust storms are natural hazards that effect on weather conditions, human health and ecosystem. Atmospheric processes are directly affected by the absorption and diffusion of radiation by dust, and dust in the cloud acts as a nucleus of congestion. The main dust areas in the world are flat topographically dry areas with erosion-sensitive soil and poor vege...

Modeling Time Resolved Light Propagation Inside a Realistic Human Head Model

Background: Near infrared spectroscopy imaging is one of the new techniques used for investigating structural and functionality of different body tissues. This is done by injecting light into the medium and measuring the photon intensity at the surface of the tissue.Method: In this paper the different medical applications, various imaging and simulation techniques of NIRS imaging is described. ...

A Case Study of the Development of an Agent-based Simulation in the Traffic Signal Control Domain using an MDD Approach

Model-driven development (MDD) is an approach for supporting the development of software systems, in which high-level modeling artifacts drive the production of low-level, time and effort-consuming artifacts, such as source code. Previous work on its use showed that it significantly increases development productivity, given that the effort is focused on the business domain instead of technical ...

A Novel Method for Modeling and Simulation of Asymmetrical Impedance-source Converters

Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesn’t use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been...

Evaluating the results of Hormuz strait wave simulations using WAVEWATCH-III and MIKE21-SW

In this study, the capabilities of WAWEWATCH-III and MIKE21-SW for predicting the characteristics ofwind-generated waves in Hormuz Strait are evaluated. The numerical models have been set up using Input data including GFS wind with 5° spatial resolution and 6 hours time intervals, along with the ETOPO1 bathymetry data with 2 arc-minute spatial resolutions. The results of the two model simulatio...
