Mathematical and cartographic methods of atmospheric processes’ analysis

Formulation of the problem. The urgency of the problem posed is the need to take into account the degree of intensity and quantitative study of dangerous atmospheric processes that cover large areas and cause significant economic damage to agriculture. When solving these questions it is necessary to have an objective estimation of different factors impact including weather and climate on the level of agricultural production. This will allow to assess various indicators of agro-meteorological conditions more reasonably in the estimation of the cereal harvest. Analysis of recent research and publications. The study of atmospheric processes and their effect on agricultural crops are devoted to in the works of V.V. Dokuchaev, P.I. Brоunоv, P.І. Kоlоskоv, G.Т. Sеlyaninov А.M. Аlpаtev S.А.

The article considers the questions of scientific research application and cartographical and mathematical methods. The following tasks are defined: to study the initial preconditions and methodological support in the study of this problem; to analyze the data of hydrometeorological service; to determine the empirical relationships of the spatial-temporal structure in the development of arid phenomena on the territory of Kharkiv region. Presentation of the main research material. In this paper, an attempt is made to use quantitative characteristics of environmentally hazardous atmospheric phenomena development for the analysis of their formation and influence on human economic activity. To do this, we used a cartographic and mathematical method of research. It consists in the fact that natural phenomena and, in particular, environmentally dangerous ones are placed on a map in the system of conditional signs and then are analyzed by methods of mathematical statistics, quantitative characteristics of the investigated phenomenon. The apparatus of mathematical statistics helps to solve probabilistic tasks of cartographic representation of natural phenomena, as well as to study various connections between natural phenomena reflected on maps, to measure and assess them. Involvement of the mathematical apparatus in the study of the cartographic image stems from the need for in-depth knowledge of the phenomena essence depicted in the maps. The study of natural phenomena without application of the map-mathematical method is considered to be one-sided since this does not take into account one of the important aspects of any study - quantitative relations and regularities. The result of the research is an analysis of statistical indicators of agricultural crops harvest and hydrometeorological conditions in Kharkiv region. Having analyzed these indicators, we determined that quantitative dependence of the crop on the number of dry days has a complex nonlinear multi-parameter appearance. At the same time, close connection between the harvest of corn and sugar beets with weather conditions was very significant, as indicated by the large correlation coefficient between them, equal to 0.87-0.90. We worked out a hypothesis about the form of functional dependence between these components. Using the mathematical modeling method to analyze the spatio-temporal structure of natural-anthropogenic phenomenon development allows us to unify the hydrometeorological characteristics. It can be used in different fields of science, in particular, in recreational geography. The apparatus of mathematical statistics helps to reliably solve the cartographic representation tasks of natural phenomena, as well as to study the versatile links between natural and anthropogenic objects, which are reflected on the maps, measure and estimate them. Conclusions. Cartographic and mathematical research method is an important component in the study of natural phenomena and processes and helps to solve probabilistic tasks of cartographic representation of natural phenomena, as well as to study the versatile relationships between natural phenomena reflected on maps, measure and quantitatively assess them.

Foreword to the Special Issue on Modeling and Simulation of Remote Sensing Data

The papers in this special issue focus on the deployment modeling and simulation in remote sensing applications which play important roles in the development and application of remote sensing technology. While modeling occurs in many aspects of remote sensing including in the representation of natural phenomena and in the development and use of data analysis algorithms, a particular role of models is in the creation of the signatures and signals that lead to the remotely sensed measurements from which we can extract information about the scene.

Ecocriticism and Persian and Greek Myths about the Origin of Fire

In his article "Ecocriticism and Persian and Greek Myths about the Origin of Fire" Massih Zekavat argues that some contemporary ecological biases are rooted in ancient thought. Further, Zekavat argues that the study of mythology is relevant to the understanding of culture and ecology thus assisting ecocriticism. The investigation of man/woman, culture/nature, and human/nature binary oppositions conveys that Greek and Persian myths are mostly anthropocentric and androcentric. Zekavat postulates that one way to revise contemporary ecological conceptions is to study myths to shed light on the mind and context of their creators and believers, their representation of natural phenomena, and their continuous impact on future generations through their adaptive and appropriative resonances in cultural production.

The influence of the final cause doctrine on anatomists of the sixteenth and seventeenth centuries concerning selected anatomical structures of the head and neck

The Doctrine of Final Cause, taken from Aristotle's "causes" and modified by Claudius (Aelius) Galen (of Pergamon) stated that for an anatomical part to exist it must have a "cause," not an end point, but a purpose or goal, natural or divine. This affected the renaissance anatomist's thinking. We explore this doctrine's relationship with human head and neck anatomy from antiquity's Aristotle and Galen, and the leading renaissance anatomists from the 16th and 17th centuries. Their relevant writings were influenced by religious and political beliefs and varied from humanistic to reactionary. Tracing anatomical controversies through these works reveal the humanism of Vesalius and others as paralleling the humanists of art and literature. These controversies illustrate how the body was used to demonstrate function, uses, and causes from higher sources. Humanists advanced the social, philosophical, intellectual, literary, and medical/anatomical thoughts of this period. They stood between the Christian church of the Middle Ages and modern science. Like religion, medicine and anatomy had its own revealed sources of knowledge and had sacred texts like Galen's. Vesalius' the Fabrica and the woodcuts established suddenly the beginning of modern observational science and art as the direct and faithful representation of natural phenomena. They displayed anatomy such that others could understand, including errors of Galen, bringing Vesalius into ecclesiastical conflict. Evolutionary scientists today see mutations as favorable or unfavorable depending on the environment. Mutations are random or directed by divine plan, according to perspectives of this ancient debate.

<b>Boltzmann et la Mécanique Classique</b><br>DOI:10.5007/1808-1711.2011v15n2p361

The purpose of the article is to present the ideas that the Austrian physicist Ludwig Boltzmann (1844-1906) developed on the role of classical mechanics in physics. He had elaborated them at a time when classical mechanics began to be considered as not being any more the ground for all other physical theories. Boltzmann never accepted this conclusion. He rejected it, developing at the same time some ideas on the epistemological nature of scientific theories. According to him, scientific theories are representations of natural phenomena.

Computer graphics for water modeling and rendering

A key topic in computer graphics is the realistic representation of natural phenomena. Among the natural objects, one of the most interesting (and most difficult to deal with) is water. Its inheren...

Clea: Aims and Activities

The Liaison Committee between School-Teachers and Astronomers (in French, “Comité de Liaison Enseignants Astronomes” or CLEA) was officially created about ten years ago under its present form, but its story began in 1970. In that time, there was no astronomy at all in French school programs, neither in elementary nor in secondary schools.A discussion was beginning about introducing physics earlier in the curriculum, with a specific purpose, the main ideas being (i) to avoid too much formalism (and formalism is a strong general characteristic of French science teaching) and (ii) to concentrate on experimentation and on the various representations of natural phenomena.

Represented Reality and Literary Models: European Autumn on Israeli Soil

This paper presents one aspect of an ongoing study of the development of literary representations of reality. More specifically, the study, and the paper, deal with transitions, from the formation of literary models in a particular cultural setting to their acculturation in different cultural contexts. The complete study encompasses various literary representations of natural phenomena, such as a specific plant or animal, a season, or a particular identifiable geographical place. The common feature of such phenomena is the fact that their reality-base can be easily traced even in texts which are not written in a conventionally realistic manner. For reasons which will be explained later, the paper focuses on representations of autumn.

Modeling of Plant Growth

The notion of modeling in science has many connotations. There are physical models, such as the atomic models of chemistry which consist of wooden or plastic balls proportional in size to atoms, together with connectors to represent chemical bonds, or realistic sculptures representing the overaIl form or the histology of an organ such as a leaf, etc. In enzyme kinetics, reaction diagrams are frequently used, in which symbols for reactants are connected by arrows to indicate theorized reac­ tions. Similar diagrams are also used in less weIl understood areas of plant physi­ ology such as the photoperiodic induction of flowering. In many cases a model is in the form of a differential equation, or a system of differential equations, or equations which result from the solution of differential equations, in which the variables and parameters are intended to correspond to measurable attributes and relationships in a system which is being investigated. Recently, logical systems have been proposed to model the development of organisms, the L-systems of Linden­ mayer (50, 51), which can be studied by the methods which are used in automaton theory, related to computer applications. There are many other sorts of models, that is to say, more or less abstract representations of natural phenomena. This review will deal primarily with morphogenetic aspects of growth, that is, with dimensions and with the ceIlular aspects of form. Much of the mathematics will therefore be related to geometry. I will be concerned mainly with the use of differential equations
