Ambient diagnostics by Yang Cai

By Yang Cai

"In daily life, we regularly realize styles from ad-hoc sensors and make intuitive judgements. This procedure is called ambient diagnostics. This textbook is written for rising classes in biomedical engineering, electric engineering, and computing device technology that discover clever software program diagnostics from reasonable units, akin to sensors on cell phones, microphones, cameras, and gyroscopes.

BioMEMS and Biomedical Nanotechnology: Biomolecular Sensing, Processing and Analysis

Quantity four of the multi-volume reference, BioMEMS and Biomedical Nanotechnology В is a balanced overview of key elements of BioMEMS sensors, together with (i) BioMEMS sensors and fabrics, (ii) technique of manipulating organic entities on the microscale, and (iii) micro-fluidics and characterization. those 3 sections offer a succinct overview of vital issues inside a unmarried quantity.

Advanced Probability Theory for Biomedical Engineers

This is often the 3rd in a chain of brief books on likelihood conception and random tactics for biomedical engineers. This booklet specializes in general likelihood distributions ordinarily encountered in biomedical engineering. The exponential, Poisson and Gaussian distributions are brought, in addition to vital approximations to the Bernoulli PMF and Gaussian CDF.

Negative Spaces According to the pioneer of AI, Herbert A. Simon, “An ant, viewed as a behaving system, is quite simple. The apparent complexity of its behavior over time is largely a reflection of the environment in which it finds itself. A man, viewed as a behaving system, is quite simple. ”12 Here, an ant and a human are figures represented in a positive space; their environment is called a negative space or background. In multimedia, for every figure there is a subtractive function to obtain the negative space or background.

Chapter 6 introduces a revolutionary active sensor, Kinect, which emits infrared dots from a video camera to reconstruct the 3D surface in front of it. Digital Human Lab For centuries, people have obtained diagnostic knowledge through reasoning and experiments. Today, computational simulation is the third scientific method. 11 Chapter 13 presents a case study about how to design a remote diagnostic system with the digital human and digital device models. This method allows us to study electromagnetic strength distributions and surface properties in the microwave field, ­making it possible to test new devices on digital humans before the devices are even built.

This book covers multimedia intelligence extensively, including innovative concepts for ambient diagnoses such as point and search, the pill camera, active sensing with Kinect, digital human labs, negative and relative feature spaces, and semantic gaps. The book also introduces crowdsourcing methods for collective intelligence from online video games and social media. Here, we also discuss design strategies for ambient diagnoses, including soft ­sensors for reconfigurable abundant sensory systems, simplicity, and personalization.
