Automatic dietary monitoring using on-body sensors: Detection of eating and drinking behaviour in healthy individuals By Oliver Amft
Paperback: $16.69
Prints in 3-5 business days
In this work a novel concept is introduced, called automatic dietary monitoring (ADM). ADM attempts to replace the error-prone manual reporting of eating behaviour that is currently used in diet... More > coaching programs. ADM-based diet coaching solutions are supported by the constant trend in electronic miniaturisation, allowing to embed sensors and computers in everyday objects, including clothing, accessories, and buildings. Systems that leverage this potential of pervasive computing can support their user with personalised health status and diet coaching services. The essential functions of ADM-based solutions are sensing and recognition of the user's eating behaviour. This work evaluates on-body sensing and pattern recognition solutions for ADM.< Less
AN INVESTIGATION OF THE EFFECT OF UNSHARP MASKING AND FILTERING ON SHARPNESS AND SNR IN ASTRONOMICAL IMAGES By Gnana Prakasam Dhanushkodi
Paperback: $12.50

The book investigates the effects of unsharp masking and filtering on sharpness and signal-to-noise ratio of astronomical images. The investigation helped to arrive at a conclusion that there is... More > always a trade off between sharpness and signal-to-noise when sharpening or filtering an image. And the investigation helped to visualize the trade off, to identify the feasible outputs that can be obtained with different parameters of unsharp masking and filtering and to select the parameters in unsharp masking and filtering required to obtain a desirable output.< Less
DSP - An Interactive Approach Second Edition By Andreas Spanias
Paperback: $59.00
Prints in 3-5 business days
(1 Ratings)
This book provides a description of digital signal processing (DSP) algorithms along with a coverage of compelling modern applications including cellular telephones and MP3 players. Topics covered... More > include filter design, FFT, random signals, adaptive filters, and speech/audio processing. The mathematical underpinnings of DSP are accompanied by qualitative descriptions, solved problems, interactive computer simulations, and Java graphics. The presentation of signal processing concepts is enhanced with object-oriented programming examples supported by the universally accessible Java-DSP (J-DSP) and its mobile versions. The second edition has several new topics including 2-d image filtering, recent speech and audio processing algorithms, and new applications. This new edition has a support web site with code and video clips for J-DSP, iOS, Android and MATLAB. More than 100 new exercises added.

Because of the more and more importance given to electrical energy as a primary source of energy for the economic and social development, electrical drives are nowadays the heart of most... More > industrial processes and strongly contribute to the evolution of the industrial civilization. These drives are indeed able to provide the needed energy both for low power applications, such as household appliances, and high power systems in transportations or manufacturing machines. Due to their rising importance an efficient and reliable control system for electrical machines has become of extreme importance both to improve the performance and to reduce the energy consumption. In the last years more advanced technical solutions able to obtain the same performance of traditional systems, without using any sensor (sensorless), have been introduced into the market. Only the methods exploiting the injection of additional signals into the motor supply can be used with low and zero speed operations,< Less
Convex Optimization Euclidean Distance Geometry 2e By Dattorro
Paperback: $41.49
Prints in 3-5 business days
Convex Analysis is an emerging calculus of inequalities while Convex Optimization is its application. Analysis is the domain of the mathematician while Optimization belongs to the engineer. In... More > layman’s terms, the mathematical science of Optimization is a study of how to make a good choice when faced with conflicting requirements. The qualifier Convex means: when an optimal solution is found, then it is guaranteed to be a best solution; there is no better choice. As any convex optimization problem has geometric interpretation, this book is about convex geometry (with particular attention to distance geometry) and nonconvex, combinatorial, and geometrical problems that can be relaxed or transformed into convexity. A virtual flood of new applications follows by epiphany that many problems, presumed nonconvex, can be so transformed. This is a BLACK & WHITE paperback. A hardcover with full color interior, as originally conceived, is available at lulu.com/spotlight/dattorro< Less

More > and pain reduction for patients who explore sensory-grounded signals and follow nature using sentient awareness. This approach, which suggests a new healthcare paradigm, can also benefit health care professionals, caregivers, and family members who yearn for ways to access the sacred, but are not given enough time with their patients and loved ones, nor training, to even have a conversation about someone’s life, let alone dive into the dreaming of a person’s symptoms. This book will be inspiring for people interested in body healing, including anyone yearning for more of themselves and the ones they are working with, to be recognized and interacted with. It is a teaching tool as well as an inspiring story for all who read it." Ann Jacob, Sacred Art of Living Center< Less

Inherent Self-Control is an introductory textbook for persons interested in knowing more about the fundamental operating concepts of process controls. The text introduces the components and... More > collective operating principles of negative feedback control loops. Topical coverage includes sensors and transmitters, standard signal ranges, control loop calibration, error signal generation, continuous control operations of proportional, integral and derivative operating modes, transducers, final control elements and typical industrial processes. Mathematics through Calculus is beneficial but not required as this text was written to support a more qualitative course in contemporary controls. Calculus forms the focus of the second half of the text but again, from a more descriptive than analytical perspective. Controller tuning and fault diagnosis (trouble-shooting) is also discussed.< Less
