Predicting impulse responses in mountainous areas

5th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Wireless Networks - Catching the Mobile Future., 2002
A software prediction tool for mobile radio channel impulse response estimation is presented. The simulation model is based on the well known radar equation for reflection from hillsides which can be treated as rough surfaces and therefore scattering the power incoherently.

The problem of energy poverty in mountainous areas

IISA 2014, The 5th International Conference on Information, Intelligence, Systems and Applications, 2014
Energy poverty is a major socio-economic issue, developing fast in recent years, along with the global energy and economic crisis. The austerity oriented policies imposed, combine low incomes with increased fuel/energy prices, a fact that inevitably leads to the households' inability to adequately meet their energy needs.

Estimating ALV position in mountainous area

Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002
A method of position estimation for an ALV (autonomous land vehicle) using features of the skyline is presented. The skyline from the vision system is assumed given and is compared with a computer map, called the CAD-MAP. The algorithm consists of identifying the peak points in the camera skyline, computing the ALV position for the identified peak ...

Quantifying Energy Demand in Mountainous Areas

2015
Despite their rich energy renewable potential, mountainous areas suffer from energy poverty. A viable solution seems to be the radical turn towards renewable resources. Any tailor-cut energy planning for mountainous areas presupposes the adequate estimation of the energy demand of buildings, which in this case is hindered by the lack of long-term ...

PHYSIOGRAPHICAL CHALLENGES OF MOUNTAINOUS AREAS

The mountainous regions of the Earth have significant elevation differences even on small areas of the earth's surface, which is the main reason for the characteristic combination of natural conditions in these regions. This includes height as a leading factor, resulting in relief and a corresponding complex of natural components.

Sustainable Tourism in Mountain Areas

2000
Many countries pursue tourism development policies. In most cases, the sole aim of these policies is to promote tourism as it is believed that it has a positive effect upon value added, income and employment. The many negative effects upon nature and the environment resulting from recreation and tourism are, unfortunately, very often ignored by ...
