There has been lately a number of catastrophic events of landslides and mudslides in the mountainous region of Rio de Janeiro, Brazil. Those were caused by intense rain in localities where there was unplanned occupation of slopes of hills and mountains. Thus, it became imperative creating an inventory of landslide risk areas in densely populated cities. This work presents a way of demarcating r...

Taoi and Kotu are two ethnic minorities in Vietnam, residing in the western mountainous region of provinces: Quang Tri, Thua Thien Hue and Quang Nam. Taoi groups have a population of about 34 960 people, of which Taoi people living in Aluoi of Hue province have 29 558 people (accounting for 67.35% of Taoi in Vietnam). Kotu people in Hue have 14,629 people (23.8% of Kotu people in Vietnam). Both...

Painters and cartographers have developed artistic landscape rendering techniques for centuries. Such renderings can visualize complex three-dimensional landscapes in a pleasing and understandable way. In this work we examine a particular type of artistic depiction, panorama maps, in terms of function and style, and we develop methods to automatically generate panorama map reminiscent rendering...

Multi sensor image fusions, by which complementary information contents of the acquired images are combined, make image analysis easier for variety of applications. However, any subsequent application carried out on the fused images highly relies on the image fusion accuracy. In this regard, the image registration stage plays a crucial impact on the final accuracy. Inaccurate image registration...

The minaret and archaeological remains at Jam, in central Afghanistan, were nominated as Afghanistan's first World Heritage site in 2002. The nomination was successful despite the International Council on Monuments and Sites (ICOMOS)'s reservations about the quality and completeness of the nomination document: in particular, ICOMOS was concerned about the rudimentary mapping and imprecise defin...

In this paper, we consider long range air-to-ground (AG) communication systems which support aeronautical platforms including unmanned aerial vehicles (UAVs) in the ultra high frequency (UHF) band. For such a system, present measurement based path loss analysis and multipath characteristic results at distance of hundreds kilometers. To end, experimental AG channel system is implemented aircraft...

The complex problem of quantitative precipitation estimation in the Alpine region is tackled from four different points of view: (1) the modern MeteoSwiss network of automatic telemetered rain gauges (GAUGE); (2) the recently upgraded MeteoSwiss dual-polarization Doppler, ground-based weather radar network (RADAR); (3) a real-time merging of GAUGE and RADAR, implemented at MeteoSwiss, in which ...

A triply-nested, movable mesh model ..~as used to study the effects of mountainous terrain on the landfall of tropical cyclones onto the islands of Japan. The integration domain spanned 43" latitude and 47" longitude with finest resolution of 1/6". Numerical experiments were separately performed for three cas4~s. In each experiment a storm was embedded onto a stationary Haurwitz type wave at th...

constructed upon a height (by footing) or breaking in to the ground, in a building, making a close relation between earth and soil is of great importance. in addition, earth as a prior factor in creation of a shade and residence, plays a crucial role in architecture history. throughout the different area, earth is paid attention differently: as a source of cool (in china), a source of heat (cap...
