"Inverse limits with set-valued functions are quickly becoming a popular topic of research due to their potential applications in dynamical systems and economics. This brief provides a concise introduction dedicated specifically to such inverse limits. The theory is presented along with detailed examples which form the distinguishing feature of this work. The major differences between the theory of inverse limits with mappings and the theory with set-valued functions are featured prominently in this book in a positive light. "

"This book is primarily devoted to topics related to matrix versions of classical interpolation and moment problems. The major themes include Schur analysis of nonnegative Hermitian block Hankel matrices and the construction of Schur-type algorithms. This book also covers a number of recent developments in orthogonal rational matrix functions, matrix-valued Carathéodory functions and maximal weight solutions for particular matricial moment problems on the unit circle.​"

"While the prediction of observations is a forward problem, the use of actual observations to infer the properties of a model is an inverse problem. Inverse problems are difficult because they may not have a unique solution. The description of uncertainties plays a central role in the theory, which is based on probability theory. This book proposes a general approach that is valid for linear as well as for nonlinear problems. The philosophy is essentially probabilistic and allows the reader to understand the basic difficulties appearing in the resolution of inverse problems. The book attempts to explain how a method of acquisition of information can be applied to actual real-world problems, and many of the arguments are heuristic."

"Inverse limits provide a powerful tool for constructing complicated spaces from simple ones. They also turn the study of a dynamical system consisting of a space and a self-map into a study of a (likely more complicated) space and a self-homeomorphism. In four chapters along with an appendix containing background material the authors develop the theory of inverse limits. The book begins with an introduction through inverse limits on [0,1] before moving to a general treatment of the subject. Special topics in continuum theory complete the book. Although it is not a book on dynamics, the influence of dynamics can be seen throughout; for instance, it includes studies of inverse limits with maps from families of maps that are of interest to dynamicists such as the logistic and the tent families.

"Frontiers in Applied Mathematics
Inverse problems arise in a number of important practical applications, ranging from biomedical imaging to seismic prospecting. This book provides the reader with a basic understanding of both the underlying mathematics and the computational methods used to solve inverse problems. It also addresses specialized topics like image reconstruction, parameter identification, total variation methods, nonnegativity constraints, and regularization parameter selection methods.
Because inverse problems typically involve the estimation of certain quantities based on indirect measurements, the estimation process is often ill-posed. Regularization methods, which have been developed to deal with this ill-posedness, are carefully explained in the early chapters of Computational Methods for Inverse Problems. The book also integrates mathematical and statistical theory with applications and practical computational methods, including topics like maximum likelihood estimation and Bayesian estimation.
Several web-based resources are available to make this monograph interactive, including a collection of MATLAB m-files used to generate many of the examples and figures. These resources enable readers to conduct their own computational experiments in order to gain insight. They also provide templates for the implementation of regularization methods and numerical solution techniques for other inverse problems. Moreover, they include some realistic test problems to be used to further develop and test various numerical methods."

"Here is a clearly written introduction to three central areas of inverse problems: inverse problems in electromagnetic scattering theory, inverse spectral theory, and inverse problems in quantum scattering theory. Inverse problems, one of the most attractive parts of applied mathematics, attempt to obtain information about structures by nondestructive measurements. Based on a series of lectures presented by three of the authors, all experts in the field, the book provides a quick and easy way for readers to become familiar with the area through a survey of recent developments in inverse spectral and inverse scattering problems."

"Approximate global convergence and adaptivity for coefficient inverse problems is the first book in which two new concepts of numerical solutions of multidimensional Coefficient Inverse Problems (CIPs) for a hyperbolic Partial Differential Equation (PDE) are presented. Two central questions for CIPs are addressed, how to obtain a good approximations for the exact solution without any knowledge of a small neighborhood of this solution, and how to refine it given the approximation.
The book also combines analytical convergence results with recipes for various numerical implementations of developed algorithms. The developed technique is applied to two types of blind experimental data, which are collected both in a laboratory and in the field. The result for the blind backscattering experimental data collected in the field addresses a real world problem of imaging of shallow explosives."

"Bauksit, sebagai bijih utama aluminium, mempunyai kualitas yang baik jika mengandung kadar alumina (Al2O2) yang tinggi dan reaktif silika (RSiO2) rendah. Penelitian ini dilakukan untuk memetakan distribusi spasial kadar Al2O3 dan RSiO2 menggunakan metode interpolasi ordinary kriging (OK) dan inverse distance weighting (IDW). Fitting variogram dilakukan dengan model spherical, exponential, dan gaussian, dan pemilihan variogram dilakukan dengan parameter residual sum of square (RSS). Dalam proses interpolasi IDW menggunakan power 1, 2, 3 dan 4. Evaluasi metode interpolasi terbaik dilakukan dengan parameter root mean square error (RMSE) dan mean error (ME). Hasil penelitian menunjukkan bawa metode interpolasi OK lebih baik dibandingkan dengan metode IDW. Peta hasil interpolasi OK menggambarkan bahwa distribusi bauksit dengan konsentrasi kadar Al2O3 ≥ 48% dan RSiO2 ≤ 5% menempati kurang lebih 50% dari luas daerah penelitian. Distribusi bauksit dengan kadar tersebut masih terbuka dan menerus ke arah utara, barat dan tenggara."

"Metode numerik eksplisit tahap tunggal pada umumnya hanya menyelesaikan persamaan diferensial biasa order pertama. Pada tugas akhir ini penulis mencoba menggabungkan beberapa cara substitusi, approksimasi dan diskritisasi, yang mana dengan penambahan fasilitas tersebut, metode Runge-Kutta dan metode Euler mampu menyelesaikan sistim persamaan diferensial dan persamaan diferensial parsil dengan batasan-batasan tertentu. Gabungan metode diskritisasi dan numerik ini disebut metode garis lurus Euler dan metode garis lurus Runge-Kutta."
