Academic literature on the topic 'Selective parameter'

The textbook describes the physical foundations, theory, principles of selection and calculation of the main parameters of spring suspension schemes, discusses the issues of fitting crews into curves, vertical dynamics of the traction drive, the use of coupling weight and vibrations of electric rolling stock.
 It is intended for the training of certified specialists in the direction of "Railway rolling stock".

The physical foundations, theory, principles of selection and calculation of the main parameters of spring suspension schemes are presented, the issues of fitting crews into curves, the dynamics of traction drive, the use of coupling weight and vibrations of electric rolling stock, and the design features of modern locomotives are considered.
 For students and teachers, as well as anyone interested in this topic.

The monograph presents a methodology for assessing the vulnerability of landscapes to external influences. A comparative analysis of the concepts of "stability", "sensitivity", "vulnerability" in relation to natural complexes. An overview of existing methods for assessing the vulnerability of natural complexes is presented. The author's method of assessing the vulnerability of landscapes to anthropogenic impacts is described. The methodology is based on: selection and justification of criteria for assessing the vulnerability of landscapes; preparation of a parametric matrix and gradation of assessment criteria in accordance with the developed vulnerability classes; calculation of weighting factors of vulnerability assessment parameters; selection of optimal territorial operational unit for landscape vulnerability assessment. The method is implemented in the GIS environment "Assessment of vulnerability of landscapes of the Kaliningrad region to anthropogenic impacts", created by the authors using modern geoinformation products. The specificity of spatial differentiation of different landscapes in terms of vulnerability to anthropogenic impacts at the regional and local levels is revealed. It is stated that the use of the methodology for assessing the vulnerability of landscapes to anthropogenic impacts and its integration into the system of nature management will ensure a balanced account of geoecological features and environmental priorities in territorial planning.
 It is of interest to specialists in the field of rational nature management, environmental protection, spatial planning.
