Due to the rapid development of motor vehicle Driver Assistance Systems (DAS), the safety problems associated with automatic driving have become a hot issue in Intelligent Transportation. The traffic sign is one of the most important tools used to reinforce traffic rules. However, traffic sign image degradation based on computer vision is unavoidable during the vehicle movement process. In orde...

This paper presents the design of optimized PV-Solar and Wind Hybrid Energy System for GSM/CDMA type mobile base station over conventional diesel generator for a particular site in south India (Chennai). For this hybrid system ,the meteorological data of Solar Insolation, hourly wind speed, are taken for Chennai (Longitude 80 ο .16’and Latitude 13 ο .5’ ) and the pattern of load consumption of ...

Observational evidence of the location of a dayside high-latitude ionospheric current (DPY current) with respect to the different regimes of the high-latitude magnetosphere is obtained by analyzing data from the magnetometer chain along the west coast of Greenland in conjunction with simultaneous measurements from the newly established incoherent-scatter radar facility at Sondre Stromfjord. The...

The high altitude meteorological parameters include longitude, latitude, atmospheric pressure, temperature, humidity, etc., which are influenced between each parameter, therefore, it is very important to deal with and analyze these parameters. In this paper, we employ MATLAB software, research the basic algorithm of BP neural network, compare resilient BP algorithm, the FletcherReeves algorithm...

In the information age and with explosively increasing volumes of remote sensing, model and other Earth Science data available, scientists are now facing challenges to find and to access interesting data sets effectively and efficiently through the Internet. In this paper, we first discuss the DIstributed MEtadata Server (DIMES) prototype system. Designed to be flexible yet simple, DIMES uses X...

Three main tidal gravity prediction programs are available through the ICET WEB site: PREDICT from ETERNA 3.4, MT80W, T-soft. The characteristics of these programs are discussed in Ducarme B., 2006 Comparison of some tidal prediction programs and accuracy assessment of tidal gravity predictions. Bull. Inf. Marées Terrestres, 141, 11175-11184 The input format of the three programs is really diff...

Deforestation is associated with increased atmospheric CO2 and alterations to the surface energy and mass balances that can lead to local and global climate changes. Previous modelling studies show that the global surface air temperature (SAT) response to deforestation depends on latitude, with most simulations showing that high latitude deforestation results in cooling, low latitude deforestat...

About 34 million years ago, Earth's climate shifted from a relatively ice-free world to one with glacial conditions on Antarctica characterized by substantial ice sheets. How Earth's temperature changed during this climate transition remains poorly understood, and evidence for Northern Hemisphere polar ice is controversial. Here, we report proxy records of sea surface temperatures from multiple...

This paper introduces a water quality data measurement and analysis system equipped in underwater robot. The system consists of sonar navigation module, inertial navigation module equipped in underwater robot, data processing module and sensor detection module. Sonar navigation module and inertial navigation module equipped in underwater robot are separately used to detect current speed, azimut...
