Recent advancements in signal processing and computerised methods are expected to underpin the future progress of biomedical research and technology, particularly in measuring and assessing signals and images from the human body. This book focuses on singular spectrum analysis (SSA), an effective approach for single channel signal analysis, and its bivariate, multivariate, tensor based, complex-valued, quaternion-valued and robust variants. SSA currently has numerous applications in detecting abnormalities in quasi-periodic biosignals, such as electrocardiograms, (ECGs or EKGs), oxygen levels, arterial pressure, and electroencephalograms (EEGs). Singular Spectrum Analysis of Biomedical Signals presents relatively newly applied concepts for biomedical applications of SSA, including: Signal source separation, extraction, decomposition, and factorization Physiological, biological, and biochemical signal processing A new SSA grouping algorithm for filtering and noise reduction of genetics data Prediction of various clinical events The book introduces a new mathematical and signal processing technique for the decomposition of widely available single channel biomedical data. It also provides illustrations of new signal processing results in the form of signals, graphs, images, and tables to reinforce understanding of the related concepts. Singular Spectrum Analysis of Biomedical Signals enhances current clinical knowledge and aids physicians in improving diagnosis, treatment and monitoring some clinical abnormalities. It also lays groundwork for progress in SSA by making suggestions for future research.

Flow Injection Analysis of Food Additives gives you the tools you need to analyze food and beverage additives using FIA. This sets it apart from other books that simply focus on the theoretical basis and principles of FIA or on the design of equipment, instrumentation, manifold, and setting mechanism. Truly unprecedented in its scope, this book represents the work of 80 authors from 14 countries who combine efforts to give you the first review on measurements of additives and other substances by FIA in relation to the use of additives in food. The book consists of ten sections. The first section provides an introduction to the topic and reviews the origin of FIA, including recent developments and future trends. The next six sections discuss the determination of additives. These sections are divided based on the official classification of additives according to function by the EU. In the final three sections, you will find a review of the determination of antioxidant capacity, antimicrobial effects, and acidity by FIA. All chapters are organized in the same way: The first part begins with a small introduction in relation to the importance of the additive or compound in foods and beverages and discusses the legislation affecting their use and control. The second part focuses on the determination of the compound or additive by FIA in different foods or beverages, with sample preparation and extraction from a food/beverage on the one hand and FIA methods used for the separation and detection on the other.

Capillary electrophoresis (CE) and microfluidic chip (MC) devices are relatively mature technologies, but this book demonstrates how they can be integrated into a single, revolutionary device that can provide on-site analysis of samples when laboratory services are unavailable. By introducing the combination of CE and MC technology, Microfluidic Chip-Capillary Electrophoresis Devices broadens the scope of chemical analysis, particularly in the biomedical, food, and environmental sciences. The book gives an overview of the development of MC and CE technology as well as technology that now allows for the fabrication of MC-CE devices. It describes the operating principles that make integration possible and illustrates some achievements already made by the application of MC-CE devices in hospitals, clinics, food safety, and environmental research. The authors envision further applications for private and public use once the proof-of-concept stage has been passed and obstacles to increased commercialization are addressed. A summary of the current methodology and application of MC-CE devices, including their merits, limitations, and potential, closes the book. It highlights the path to be taken for future development of MC-CE and anticipates new advances in technology that will increase their performance and use as powerful analytical tools. With enhanced power, their scope of applications will widen and yield new benefits to researchers and the general public.
