Book Description
The seismoelectric method consists of measuring electromagnetic signals associated with the propagation of seismic waves or seismic sources in porous media. This method is useful in an increasing number of applications, for example to characterize aquifers, contaminant plumes or the vadose zone. This book provides the first full overview of the fundamental concepts of this method. It begins with a historical perspective, provides a full explanation of the fundamental mechanisms, laboratory investigations, and the formulation of the forward and inverse problems. It provides a recent extension of the theory to two-phase flow conditions, and a new approach called seismoelectric beamforming. It concludes with a chapter presenting a perspective on the method. This book is a key reference for academic researchers in geophysics, environmental geosciences, geohydrology, environmental engineering and geotechnical engineering. It will also be valuable reading for graduate courses dealing with seismic wave propagation and related electromagnetic effects.

Book Description
Control over Communication Networks Advanced and systematic examination of the design and analysis of networked control systems and multi-agent systems Control Over Communication Networks provides a systematic and nearly self-contained description of the analysis and design of networked control systems (NCSs) and multi-agent systems (MASs) over imperfect communication networks, with a primary focus on fading channels and delayed channels. The text characterizes the effect of communication channels on the stability and performance of NCSs, and further studies the joint impact of communication channels and network topology on the consensus of MASs. By integrating communication and control theory, the four highly-qualified authors present fundamental results concerning the stabilization of NCSs over power-constrained fading channels and Gaussian finite-state Markov channels, linear-quadratic optimal control of NCSs with random input gains, optimal state estimation with intermittent observations, consensus of MASs with communication delay and packet dropouts, and synchronization of delayed Vicsek models. Simulation results are given in each chapter to demonstrate the developed analysis and synthesis approaches. The references are comprehensive and up-to-date, enabling further study for readers. Topics covered in Control Over Communication Networks include: Basic foundational knowledge, including control theory, communication theory, and graph theory, to enable readers to understand more complex topics The stabilization, optimal control, and remote state estimation problems of linear systems over channels with fading, signal-to-noise constraints, or intermittent measurements Consensus problems of MASs over fading/delayed channels, with directed and undirected communication graphs Control Over Communication Networks provides a valuable unified platform for understanding the analysis and design of NCSs and MASs for researchers, control engineers working on control systems over communication networks, and mechanical engineers working on unmanned systems. Preliminary knowledge of linear system theory and matrix analysis is required.

Book Description
This thesis investigates the channels with an altruistic helper, a party that observes the channel noise - or more generally, the channel state - and produces rate-limited quantization to assist the data transmission. Factors to be considered include various notions of capacity, different assistance revelation, and the effect of message cognizance and feedback. The thesis is structured in two primary parts. In the first part, four different notions of capacity are considered on the additive noise channels with a helper: The first notion, referred to as the erasures-only capacity, requires that the decoder must avoid unconscious errors but may declare decoding failures with a small probability. We prove that on the memoryless modulo-additive noise channels (MMANCs), the erasures-only capacity matches the Shannon capacity. This result is generalized to continuous additive noise channels. The second and third notions considered are the listsize capacity and the cutoff rate. The listsize capacity requires that the decoder generate a list containing all the possible messages, and the p-th moment of the cardinality of that list converge to one for given p > 0. The cutoff rate is similar but restricts the list to messages at least as likely as the transmitted one. It is demonstrated that on the MMANCs, the listsize capacity equals the cutoff rate, and the same result is established on the Gaussian channel with decoder assistance. The fourth notion examined is the zero-error capacity, which requires that the message be decoded exactly with zero probability of error. On the MMANCs, both the scenarios with and without feedback are studied. In its presence, a complete solution of said capacity is provided. In its absence, a solution is provided when the alphabet size is prime. For all other cases, upper and lower bounds on the capacity are derived, leading to a necessary and sufficient condition for its positivity. Thanks to the help, the zero-error capacity may increase by more than the help ́s rate,and it can be positive yet smaller than one bit. The second part of the thesis focuses on the effects of message cognizance and feedback: In particular, the capacity of a state-dependent discrete memoryless channel (SD-DMC) is derived for the setting where a message-cognizant rate-limited helper observes the state sequence noncausally and provides its description to both encoder and decoder. ...

Book Description
Single-channel recording has become a widely used tool for the study of ion permeation mechanisms in biological membranes. Whereas the technique might have been considered an "art" after its introduction in 1976, it developed into a relatively simple method after it became possible to obtain high-resistance (several gigaohm) membrane-pipette seals. In the summer of 1982, a course on the technique was held at the Ettore Majorana Center for Scientific Culture in Erice, Sicily. It brought together people from most of the laboratories involved in patch clamping at that time. During the course, it became apparent that the technique had reached a state of maturity. Repeatedly, the opinion was expressed that a detailed description of all the aspects of the technique including representative examples of results should be available. We therefore asked the course instructors, as well as several other colleagues, to provide chapters on selected topics in order to produce this volume. The different variants of patch clamping were described quite extensively in an article by Hamill, Marty, Neher, Sakmann, and Sigworth (Pflugers Archiv 391:85) in 1981. Rather than repeating this survey in an introductory chapter, we chose to reprint that article in the Appendix of this volume (by permission of Springer-Verlag). The methods section will, therefore, go straight into detailed aspects of the technol ogy.

Book Description
A modified Linear Estimation Approach was performed to reconstruct current sources within the heart. Based on MRI data sets the Boundary Element Method was used to create tailored multicompartment models of the human thorax which were used to solve the forward problem of magnetocardiography. The ability of the proposed method was demonstrated for the localization of a single current dipole as an example of a focal source. By means of introducing small shiftings to all reconstruction dipoles during linear estimation solution as well as performing a successive focussing strategy ignoring places without significant electrical activity the method could easily be extended to the reconstruction of real 3D sources. Based on a special minimum-norm solution the source volume can be estimated applying a finite element approximation using cube elements. The size of an extended current source can be estimated by superimposing the reconstructed dipoles to an equivalent dipole and comparing the corresponding volume with the sphere which would be related to the equivalent dipole. The deviation of these volumes can be taken as a criterion for non-dipolarity of sources.
