Coding and Decoding: Seismic Data


Book Description

Currently, the acquisition of seismic surveys is performed as a sequential operation in which shots are computed separately, one after the other. This approach is similar to that of multiple-access technology, which is widely used in cellular communications to allow several subscribers to share the same telephone line. The cost of performing various shots simultaneously is almost identical to that of one shot; thus, the savings in time and money expected from using the multishooting approach for computing seismic surveys compared to the current approach are enormous. By using this approach, the long-standing problem of simulating a three-dimensional seismic survey can be reduced to a matter of weeks and not years, as is currently the case. - Investigates how to collect, stimulate, and process multishooting data - Addresses the improvements in seismic characterization and resolution one can expect from multishooting data - Aims to educate the oil and gas exploration and production business of the benefits of multishooting data, and to influence their day-to-day surveying techniques

Fundamentals of Electrocardiografia (ECG) With Arduino Uno


Book Description

The concept of this book is ECG signals- Electrocardiography is connected with Arduino UNO- microcontroller. This book demonstrates how our heart waves can be connected to a microcontroller. What kind of obstruction or change occurs in the wave according to the different changes of the atmosphere can be known from this book. The ECG Signal plays an important role in the diagnosis of heart diseases and disorders. An ECG is a significant physiological signal for diagnosis of cardiac disease. Modern usage of monitoring devices with electrocardiogram is increasing. Huge storage space and large quantities of data are that, and ECG compression is required for efficient storage and it has been extracted from a medical database. Aninteresting research line focuses on transforming the original one-dimensional waveforms of the ECG into two-dimensional information, followed by a processing stage using image processing tools. Many cardiac abnormalities can be observed with the aid of an ECG interpretation including inadequate blood flow, heart muscle death due to coronary thrombosis and heart muscle enlargement. Arduino can be used to for the development of interactive objects, taking inputs to control outputs. It is connected to the Arduino hardware to communicate and upload sketches. Arduino can read information from input devices such as Trimmer(potentiometer), Antenna, Sensors, e.t.c, and can also send data to the output devices such as Speakers, LED, DC motor, LCD Screen, e.t.c. User communities are groups of people using a given product, the Arduino in this case. So, the design has been enhanced, and it helps drive the Arduino board for direction to future.




Handbook of Geomathematics


Book Description

During the last three decades geosciences and geo-engineering were influenced by two essential scenarios: First, the technological progress has changed completely the observational and measurement techniques. Modern high speed computers and satellite based techniques are entering more and more all geodisciplines. Second, there is a growing public concern about the future of our planet, its climate, its environment, and about an expected shortage of natural resources. Obviously, both aspects, viz. efficient strategies of protection against threats of a changing Earth and the exceptional situation of getting terrestrial, airborne as well as spaceborne data of better and better quality explain the strong need of new mathematical structures, tools, and methods. Mathematics concerned with geoscientific problems, i.e., Geomathematics, is becoming increasingly important. The ‘Handbook Geomathematics’ as a central reference work in this area comprises the following scientific fields: (I) observational and measurement key technologies (II) modelling of the system Earth (geosphere, cryosphere, hydrosphere, atmosphere, biosphere) (III) analytic, algebraic, and operator-theoretic methods (IV) statistical and stochastic methods (V) computational and numerical analysis methods (VI) historical background and future perspectives.
