Fuzzysets and series analysis for visual decision support in spatial data exploration
The research underlying this Ph.D. thesis concerns the development of procedures for evaluating predefined classification techniques for spatial data. The definition of fuzzysets and the analysis of fuzzy series are proposed as tools

A fuzzy classification of remote sensing data is carried out appying a modified version of FCM algorithm with supervised cluster centers. There are five steps, each one with dicithomic recognition method of land use classes.
An introduction to the theory of fuzzysets in the context of the construction of representational, spatial economic theory in Towards the dynamic analysis of spatial systems.
Soil horizons are the results of pedological processes and classes of soil horizon descriptions are seen as fundamental to soil classification. A fuzzy-sets approach to horizon classes is suggested to deal with the intergrading and multivariate

The aim of this paper is to present a new technique that allows more robust estimation of DEM quality and its influence on sediment budgets derived from DEM differencing. The novel contributions set out here are : 1) a new technique for estimating
A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN), generalized linear model (GLM), and multiple linear regression (MLR) models are appropriate
for prediction of soil wet aggregate stability (as quantified by the mean weight diameter, MWD) in a highly mountainous watershed (Bazoft watershed, southwestern Iran). Three different sets of available data including soil properties alone, topographic attributes

The majority of documented climatic data set biases can be divided into two categories : physical biases and calendar biases. Previous homogenization efforts for prominent temperature and precipitation data sets are detailed in this review. Numerous
physical biases are accounted for in these homogenization efforts and a debate exists in the literature regarding the effectiveness of these bias adjustment methods, leading some investigators to question the suitability of these adjusted data sets
for the identification of large-scale climate change signals. Calendar biases are not addressed in previous homogenization efforts. After a brief analysis, a calendar bias known to exist in homogenized data sets (the leap year bias) is identified in the CRUTEM3v
, an important global monthly near-surface air temperature data set.
Varhu nalicieto na snop ot kosi razlomi v Sipcenska Stara planina On the presence of a set of oblique faults, in the Sipcenski Balkan
C. r. par Ju. Karagjuleva, Abstr. Bulg. scient. Lit., 1976-2, n 159: The Sipka anticline is fragmented by a set of oblique faults of a normal-fault-slip-fault character, striking 30 to 40. The Buzludza fault set is best expressed at the boundary
between the core and the mantle of the anticline. It is of comparatively old age. To the west of it, the calcareous Middle and Upper Triastic is of wider occurence. Tithonian and Valanginian occur only to the west of this set, and Turonian only to the east
of it. The fault set is over 2km wide, and the total amplitude of the side slips along it is about 1km.
