Book Description
Resolving Spectral Mixtures: With Applications from Ultrafast Time-Resolved Spectroscopy to Superresolution Imaging offers a comprehensive look into the most important models and frameworks essential to resolving the spectral unmixing problem—from multivariate curve resolution and multi-way analysis to Bayesian positive source separation and nonlinear unmixing. Unravelling total spectral data into the contributions from individual unknown components with limited prior information is a complex problem that has attracted continuous interest for almost four decades. Spectral unmixing is a topic of interest in statistics, chemometrics, signal processing, and image analysis. For decades, researchers from these fields were often unaware of the work in other disciplines due to their different scientific and technical backgrounds and interest in different objects or samples. This led to the development of quite different approaches to solving the same problem. This multi-authored book will bridge the gap between disciplines with contributions from a number of well-known and strongly active chemometric and signal processing research groups. Among chemists, multivariate curve resolution methods are preferred to extract information about the nature, amount, and location in time (process) and space (imaging and microscopy) of chemical constituents in complex samples. In signal processing, assumptions are usually around statistical independence of the extracted components. However, the chapters include the complexity of the spectral data to be unmixed as well as dimensionality and size of the data sets. Advanced spectroscopy is the key thread linking the different chapters. Applications cover a large part of the electromagnetic spectrum. Time-resolution ranges from femtosecond to second in process spectroscopy and spatial resolution covers the submicronic to macroscopic scale in hyperspectral imaging. Demonstrates how and why data analysis, signal processing, and chemometrics are essential to the spectral unmixing problem Guides the reader through the fundamentals and details of the different methods Presents extensive plots, graphical representations, and illustrations to help readers understand the features of different techniques and to interpret results Bridges the gap between disciplines with contributions from a number of well-known and highly active chemometric and signal processing research groups

Book Description
This book explains in a didactic way the basic concepts of spectral mixing, digital numbers and orbital sensors, and then presents the linear modelling technique of spectral mixing and the generation of fractional images. In addition to presenting a theoretical basis for spectral mixing, the book provides examples of practical applications such as projects for estimating and monitoring deforested areas in the Amazon. In its seven chapters, the book offers remote sensing techniques to understand the main concepts, methods, and limitations of spectral mixing for digital image processing. Chapter 1 addresses the basic concepts of spectral mixing, while chapters 2 and 3 discuss digital numbers and orbital sensors such as MODIS and Landsat MSS. Chapter 4 details the linear spectral mixing model, and chapter 5 talks about how to use this technique to create fraction images. Chapter 6 offers remote sensing applications of fraction images in deforestation monitoring, burned-area mapping, selective logging detection, and land-use/land-cover mapping. Chapter 7 gives some concluding thoughts on spectral mixing, and considers future uses in environmental remote sensing. This book will be of interest to students, teachers, and researchers using remote sensing for Earth observation and environmental modelling.

Book Description
Chemometrics is the application of mathematics and statistics to chemical data in order to design or select optimal experimental procedures, to provide maximum relevant information, and to obtain knowledge about systems under study. This chemical discipline has constantly developed to become a mature field of Analytical Chemistry after its inception in the 1970s. The utility and versatility of chemometric techniques enable spectroscopists to perform multidimensional classification and/or calibration of spectral data that make identification and quantification of analytes in complex mixtures possible.Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. They are now being adapted for a vast number of signal processing due to their unprecedented success in terms of asymptotic optimality, spatial adaptivity and computational efficiency. In analytical chemistry, they have increasingly shown great applicability and have been preferred over existing signal processing algorithms in noise removal, resolution enhancement, data compression and chemometrics modeling in chemical studies.The aim of this Research Topic is to present state-of-the-art applications of chemometrics, in the field of spectroscopy, with special attention to the use of wavelet transform. Both reviews and original research articles on pharmaceutical and biomedical analysis are welcome in the specialty section Analytical Chemistry.

Book Description
Spices are obtained from natural sources, especially from plants, and are used in cooking food in whole or grounded forms mainly for imparting flavor, aroma, and piquancy. Besides their role in improving food quality, spices also have health benefits that are anticancer, antidiabetic, antimicrobial, antioxidant, hypolipidemic, analgesic, immunostimulant, and more. Spices are generally marketed in powder form, and their supply chain is very long and complicated, which is why they are particularly susceptible to adulteration at many points. The spice supply chain is considered to be moderately vulnerable and has an ineffective quality detection system in its final product, which is the main risk factor. There are many types of fraud nowadays related to spices such as adulteration, falsification, substitution, and inaccurate labeling. Analysis of Food Spices: Identification and Authentication provides an overview of spices of different categories, such as terpenes and terpenoids, oleoresins, alkaloids, and polyphenolics and flavonoids, as well as qualitative and quantitative guidelines for ensuring their quality and safety using modern analytical tools and techniques. The first section of the book discusses the overview, sources, and health benefits of important categories of spices such as terpenes and terpenoids (cardamom, cinnamon, clove, coriander, cumin, fennel), oleoresins (capsicum, ginger, nutmeg), alkaloids (black pepper, fenugreek), and polyphenolics and flavonoids (basil, turmeric, olive, saffron). In the second section, qualitative diagnostic features of spices are covered. In the third section, the roles of quantitative analytical techniques, such as HPLC, LC-MS, HPTLC, GC, and GC-MS, capillary electrophoresis (CE), and other recent techniques in the analysis of food spices, are also discussed. Each chapter concludes with a general reference section, which is a bibliographic guide to more advanced texts. Key Features Provides a detailed overview of different food spices of plant origin, and discusses their health benefits and uses of different analytical techniques in its quality control Explains how qualitative diagnostic features of food spices are utilized as quality control tools Describes applicability of analytical techniques like HPLC, LC-MS, GC-MS, HPTLC, and CE for quality control of food spices Emphasizes use of recent techniques such as proteomics, biosensors, and more in the analysis/quality control of food spices This book will provide important guidelines for controlling quality, safety, and efficacy issues related to food spices.

Book Description
This book provides knowledge of the basic theory, spectral analysis methods, chemometrics, instrumentation, and applications of near-infrared (NIR) spectroscopy—not as a handbook but rather as a sourcebook of NIR spectroscopy. Thus, some emphasis is placed on the description of basic knowledge that is important in learning and using NIR spectroscopy. The book also deals with applications for a variety of research fields that are very useful for a wide range of readers from graduate students to scientists and engineers in both academia and industry. For readers who are novices in NIR spectroscopy, this book provides a good introduction, and for those who already are familiar with the field it affords an excellent means of strengthening their knowledge about NIR spectroscopy and keeping abreast of recent developments.
