В настоящей работе приводятся рекомендации по применению сейсмоакустических методов при инженерно-геологических изысканиях в условиях Байкало-Амурской магистрали. Она выполнена на основе исследований ЦНИИСа, проведенных на некоторых характерных участках трассы БАМа, и опыта работы ряда организаций в районах распространения вечной мерзлоты. Исследования проводила лаборатория инженерной геологии и геофизики в содружестве с Ленгипротрансом.

Настоящие Указания предназначены в качестве методического пособия при проведении геофизических исследований на изысканиях дорог в районах распространения карота. Указания разработаны с учетом современного состояния геофизики и опыта применения ее на объектах транспортного строительства

Работа выполнена в лаборатории инвенерной геологии и геофизики ЦНИИСа кзнд.техн.наук В.А.Ряпоиовой при участии канд. геолого-минералогических наук П.И.Яковенко (Урадгипротранс).

Geophysics is a principal tool for geoscientists that helps decipher not only deeper geology but also formational processes and chronological changes in the physical property contrasts between the causative bodies and the surroundings at the different strata of the subsurface.

The science of rock physics addresses the relationships between geophysical observations and the underlying physical properties of rocks, such as composition, porosity, and pore fluid content. The Rock Physics Handbook distills a vast quantity of background theory and laboratory results into a series of concise, self-contained chapters, which can be quickly accessed by those seeking practical solutions to problems in geophysical data interpretation.

This tutorial is concerned with applications of information theory concepts in statistics, in the finite alphabet setting. The information measure known as information divergence or Kullback-Leibler distance or relative entropy plays a key role, often with a geometric flavor as an analogue of squared Euclidean distance, as in the concepts of I-projection, I-radius and I-centroid. The topics covered include large deviations, hypothesis testing, maximum likelihood estimation in exponential families, analysis of contingency tables, and iterative algorithms with an “information geometry” background. Also, an introduction is provided to the theory of universal coding, and to statistical inference via the minimum description length principle motivated by that theory. <...>

Geomagnetism is the study of the earth's magnetic field: its measurement, variation in time and space, origins, and its use in helping us to understand more about our Earth. Paleomagnetism is the study of the record left in the rocks; it has contributed much to our understanding of the geomagnetic field's past behavior and many other aspects of geology and earth history.

Data on the geomagnetic field in the Balkan region and state borders were regarded as confidential information for a long time. Unfortunately this meant that geomagnetic field information was confidential information. The Republic of Macedonia was in a complicated situation because geomagnetic investigations were carried out by experts from Belgrade, Serbia and Montenegro. When Macedonia became an independent country, a team of experts from the Faculty of Mining and Geology, Department for Geology and Geophysics in Stip and Faculty of Natural Sciences and Mathematics, Institute of Physics in Skopje, started activities to establish a Geomagnetic Observatory in Macedonia. In the last four years, with the help of Dr. Jean Rasson from Institut Royal Météorologique, Centre du Physique du Globe in Dourbes, Belgium, a network of 15 repeat stations for measurement of the geomagnetic field in the Republic of Macedonia was created. For the first time since independence, all elements of geomagnetic field were determined <...>

This book is devoted to the theory of geoelectromagnetic oscillations and waves, i.e. waves of natural origin arising in the Earth’s crust, in the ocean, in the atmosphere, in the ionosphere, in the magnetosphere and in the interplanetary medium in front of the magnetosphere.
We have sought to give a simple and clear presentation of the physical picture of the waves. When selecting the material special attention was paid to the theoretical inferences that can be easily compared with the observational data. Complicated and unwieldy calculations were omitted where possible. At the same time, where formulae have been presented without derivation, we have tried to explain their physical meaning.
