We propose a geographical visualization to support operators of coastal surveillance systems and decision making analysts to get insights in vessel movements. For a possibly unknown area, they want to know where significant maritime areas, like highways and anchoring zones, are located. We show these features as an overlay on a map. As source data we use AIS data: Many vessels are currently equ...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
This article present results for building accurate 3-D maps of urban environments with amobile SegwayRMP. The goal of this project is to use robotic systems to rapidly acquire 3-D maps, which seamlessly integrate indoor and outdoor structures. Our approach is based on an information-solution of the SLAM problem, which enables us to seamlessly integrate GPS, IMU, and scan data. 3-D models acquir...
Since the improvement of special technology, the application of GPS becomes a low-cost and popular way. The construction of digital map is the base in many GPS applications. Because of these, the construction of the map is the most important thing in the application of GPS. GPS position tracing and satellite image analyzing were the most used methods in the construction of digital map. In gener...
Map-matching algorithms aim at establishing a vehicle location on a road segment based on positioning data from a variety of sensors: GPS receivers, WiFi or cellular radios. They are integral part of various Intelligent Transportation Systems (ITS) including fleet management, vehicle tracking, navigation services, traffic monitoring and congestion detection. Our work was motivated by an idea of...
