Our research addresses the question of how to design interfaces for spatial analysis such that they support cognitive processes. In this paper we specifically target the question of map symbol design for the analysis of multivariate data, which is a common problem in cartography and related fields. We focus on star plots and the largely unaddressed question of how to assign variables to rays in...

The problem of air traffic congestion isn’t unique to developing countries like Unites States, Russia and China. How to accommodate an ever increasing flights is a global problem and a potentially dangerous one. The projections of aircrafts in the air have tremendously increased and is expected to lead to major accidents by 2015. The aircrafts have limitations of geography and limited reach of ...

growth chart is the best measure for weight monitoring of children. most factors that affect child heath show their effect on child weight. this cross sectional and descriptive analytical study was achieved to estimate malnutrition prevalence and effective factors in children under 5 years old in rural area of khoramabad province. 555 girls and 570 boys were chosen from health houses by cluster...

Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...

The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...

A novel method based on the curvelet transform and active contour method to automatically detect the ice edge in Synthetic Aperture Radar (SAR) imagery is proposed. The method utilizes the location of high curvelet coefficients to determine regions in the image likely to contain the ice edge. Using an ice edge from passive microwave sea ice concentration for initialization, these regions are th...

One of the most important processes in today's industrial world, the Nexus Interaction, is known as Water, Soil and Wastewater (WSW). The purpose of this research is to provide a network model that can be used to determine the state of the hazards caused by Irrigation of land with untreated municipal wastewater. Methods of this study include the stages: knowledge of the study area, quantitative...
