Available in PDF, EPUB and Kindle. Book excerpt: This work evaluates the pavement surface condition and detects the pavement subsurface delamination through vehicle noise collected by microphones mounted underneath a moving vehicle. Such measurements will include tire-generated sound, which carries much information about the road condition, as well as noise generated by the environment and vehicle. A careful frequency analysis of the vehicle noise is carried out to localize the frequency range for surface characteristics and subsurface delamination respectively. The Principal Component Analysis (PCA) method is applied to differentiate important information about the road condition from noisy data contributions collected while the vehicle is moving. The analysis begins with acoustic pressure measurements made over constant and known road conditions. Fourier transforms are taken over various time windows and a PCA is performed over the resulting vectors, yielding a set of principal component vectors for the road condition. The condition of each road section is characterized by a set of principal component vectors. Pavement macrotexture Mean Texture Depth (MTD) is predicted from the principal component vector and then projected to the overall pavement condition index (PCI) as well as the pavement friction and uniformity evaluation. Pavement subsurface delamination is also detected from the principal component vector. The significant accomplishments of this study are as follows: (1) localize the frequency ranges of vehicle noise related to pavement surface and subsurface features respectively; (2) demonstrate the potential for PCA to reduce noise and illustrate the procedure to apply PCA in frequency domain for noise filtering; (3) find the relationship between MTD, sound pressure and driving speed; (4) optimize the microphone placement for data collection for the MTD prediction; (5) develop a calibration-free method for the MTD prediction with an error of 16%; (6) use the predicted Equivalent MTD found by the PCA Energy Method to explore pavement friction prediction, construction non-segregation evaluation, and the contribution to PCI prediction from the acoustic aspect; (7) differentiate the stiffness of the top layer pavement within 10 cm of surface from tire/road noise, and (8) detect the subsurface delamination from the shift of frequency in peak sound pressure level.

Book excerpt: This proceedings volume chronicles the papers presented at the 35th CIB W78 2018 Conference: IT in Design, Construction, and Management, held in Chicago, IL, USA, in October 2018. The theme of the conference focused on fostering, encouraging, and promoting research and development in the application of integrated information technology (IT) throughout the life-cycle of the design, construction, and occupancy of buildings and related facilities. The CIB – International Council for Research and Innovation in Building Construction – was established in 1953 as an association whose objectives were to stimulate and facilitate international cooperation and information exchange between governmental research institutes in the building and construction sector, with an emphasis on those institutes engaged in technical fields of research. The conference brought together more than 200 scholars from 40 countries, who presented the innovative concepts and methods featured in this collection of papers.

Book excerpt: Vehicle/Tire/Road Dynamics: Handling, Ride, and NVH presents the connection between NVH and conventional vehicle dynamics where both tire and road play a key role. In this book, there is a chapter for handling dynamics that provides an introduction to ride dynamics and a chapter for ride dynamics that provides an introduction to NVH, presenting better coherence and synergy between these major areas of vehicle/tire dynamics. Accompanying the fundamental theories, case studies are given to facilitate comprehension. In addition to the experimental implementations, the state-of-the-art approaches to simulating vehicle/tire dynamics are presented from the viewpoint of both industry and academia. This new book bridges the gap for experts in tire or pavement NVH (also tire-pavement interaction noise) and those who are experts in vehicle dynamics. Conventional vehicle dynamics (e.g., handling/braking/cornering) is focused on low-frequency performance while NVH (noise/vibration/harshness) is focused on high-frequency performance. There is also another area called "ride" (comfort/stability) which focuses on mid-frequency. Presents a closed loop system for vehicle dynamics, covering handling, riden and NVH. Provides insights into how intelligent tires will enhance autonomous vehicle control and optimize multiple performances, especially for electric vehicles. Demonstrates how pavement characteristics could greatly influence vehicle handling/ride/NVH and improve/balance these performances.

The process also allows for the collection of data for use in developing or calibrating performance-prediction models. The report includes example forms and checklists for use during the conduct of an investigation. These forms can be modified to suit the particular requirements and procedures for the agency. The example forms are included with the print version of the report in CD-ROM format." --Publisher description.

Book excerpt: Visual sensors are able to capture a large quantity of information from the environment around them. A wide variety of visual systems can be found, from the classical monocular systems to omnidirectional, RGB-D, and more sophisticated 3D systems. Every configuration presents some specific characteristics that make them useful for solving different problems. Their range of applications is wide and varied, including robotics, industry, agriculture, quality control, visual inspection, surveillance, autonomous driving, and navigation aid systems. In this book, several problems that employ visual sensors are presented. Among them, we highlight visual SLAM, image retrieval, manipulation, calibration, object recognition, navigation, etc.
