Das Aufdecken von Kausalstrukturen mittels Triadenreduktion am Beispiel der Migration der Bevolkerung städtischer Gemeinden. (Revealing causal structures by means of triad reduction with the migration of the population of urban communities taken

According to a concrete example, the synthetical analysis of the results that have been obtained can be given as following: a rather good exponential ajustment would exist between the fractures number and their length whatever the azimuth taken
into account may be. The proportionality between discontinuities of different lengths would remain almost constant whatever the facies and the direction of the fractures taken into account may be. The global fracturation intensity would depend not only

En japonais Aerial photographs of Osaka, Kyoto and environs taken at the 1920's and early 1940's

Based on the principle of systematic analysis, the peculiarities in analysing geographical objects regarded as geosystems are described and the historical aspects are taken into consideration. These peculiarities consist of aspects of limitation

The results of the Biosphere-M experiment are summarized. The space photographs taken by Valeriy Kubasov and Bertalan Farkas, participants of the Soviet-Hungarian joint space flight are interpreted from geographic, oceanographic, geologic

to Bayesian hypothesis relative to the error-distribution of the data. All these questions are taken up in detail in a series of articles by P. Cazes published in the Cahiers.

A geographical evaluation is made of the features on colour slides taken from a RC model airplane from the height of 300 m. The image was digitalized by using a video camera and a frame of grabbing system. Contrast stretching, PC analysis

The author discusses the agenda, the procedure and the issues taken up at the International Symposium on geomorphological mapping which took place in Budapest, October 25-28, 1977. Methods of constructing conventional geomorphological

Measurements taken in the topsoil are used to investigate the spatial variability of soil moisture by applying methods of geostatistics. Due to the factors that act in different spatial and temporal dimensions, soil moisture of agricultural areas

Seventy-five maps are included inclued in this volume, each with an accompanying commentary written by an authority on the particular subject. Taken together, the maps show how the distribution of protest-riots connected with land, with food

, ameliorative properties of the sand) and availability of material and technological resources in the area should be taken into consideration. Two conditions must be met simultaneously : the cost of sand stabilization must be as low as possible and its nature
-protective effect as high as possible. The task can be solved by means of a model of linear programming where optimization of nature-protective and economic criterion is taken for the efficiency function. - (L'Ed.).

From 1883 exact hypsometric maps of Alp glaciers were drawn which allow a geometric comparison with present maps. In the seventies of our century the first orthophotomaps of Alp glaciers were taken. The author gives a short description of the maps

in the majority of cases. In the third part, specific coefficients are determined, using the ability to learn and recognize vegetation symbols. The extent to which the conceptions of a target group should be taken into account when compiling a legend

Geographical photography has been taken upon a geographer's own judgement. Material for this analysis came from geographical monographs and from Chirigaku Hyôron (Geographical Review of Japan). The development of geographical photography in Japan
