Book excerpt: This research evaluated pavement marking performance and developed useful degradation models for thermoplastic and paint pavement markings which can help North Carolina meet the pending FHWA minimum retroreflectivity requirements. The impacts of several important factors (such as lateral location, directionality, region, and pavement roughness) on pavement marking retroreflectivity were evaluated. With two large datasets in hand, the authors determined whether these factors had significant impacts on marking retroreflectivity. Image processing techniques were used to analyze pavement marking surface glass bead density. The authors were able to explain why paint marking retroreflectivity values degraded over time by evaluating the impact of bead density on paint marking retroreflectivity. The research reviewed existing marking retroreflectivity degradation models and developed useful new models for both thermoplastic and paint pavement markings in North Carolina. The research presented a transportation asset management system framework for estimating the current and future condition of pavement markings. The research outcomes enable the North Carolina Department of Transportation to have a better understanding of thermoplastic and paint pavement marking performance, which can lead to cost saving by maximizing pavement marking service lifecycles.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology combines solid state physics, chemistry, electrical engineering, chemical engineering, biochemistry and biophysics, and materials science. It is a highly interdisciplinary area, meaning that it involves ideas integrated from many traditional discipline. Quantum nanoscience is the application of quantum theory to the design of new nanoscale materials and devices. Quantum Nanoscience explains functionality and structure in natural or engineered nanoscale systems through quantum mechanisms such as discretisation, superposition and entanglement. In the 19th century, decades of practice with heat engines led to the new science of thermodynamics. The understanding of the world captured by thermodynamics is now part of the fabric of engineering and effective design across a vast range of different technologies. Thermodynamics, quantum nanoscience is an enabling science for engineering and design of new nanotechnologies. Molecular nanotechnology (MNT) is a technology based on the ability to build structures to complex, atomic specifications by means of mechanosynthesis. This is distinct from nanoscale materials. Based on Richard Feynman's vision of miniature factories using nanomachines to build complex products (including additional nanomachines), this advanced form of nanotechnology (or molecular manufacturing) would make use of positionally-controlled mechanosynthesis guided by molecular machine systems. MNT would involve combining physical principles demonstrated by chemistry, other nanotechnologies, and the molecular machinery of life with the systems engineering principles found in modern macroscale factories. This book introduces the reader to the world of nanotechnology by giving them in-depth details of different aspects of the field.

Download or read book Remote Sensing of Precipitation written by Silas Michaelides and published by MDPI. This book was released on 2019-07-23 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precipitation is a well-recognized pillar in global water and energy balances. An accurate and timely understanding of its characteristics at the global, regional, and local scales is indispensable for a clearer understanding of the mechanisms underlying the Earth’s atmosphere–ocean complex system. Precipitation is one of the elements that is documented to be greatly affected by climate change. In its various forms, precipitation comprises a primary source of freshwater, which is vital for the sustainability of almost all human activities. Its socio-economic significance is fundamental in managing this natural resource effectively, in applications ranging from irrigation to industrial and household usage. Remote sensing of precipitation is pursued through a broad spectrum of continuously enriched and upgraded instrumentation, embracing sensors which can be ground-based (e.g., weather radars), satellite-borne (e.g., passive or active space-borne sensors), underwater (e.g., hydrophones), aerial, or ship-borne.

This book was released on 2014-09-26 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doppler radars provide unique 3D information about precipitating clouds in high spatial and temporal resolutions. However, the observed quantities (reflectivity, Doppler velocity and polarization properties) are not directly comparable to the variables of numerical prediction models. In order to enable radar data assimilation, a comprehensive modular radar forward operator has been developed.

Available in PDF, EPUB and Kindle. Book excerpt: Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this seventh edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy, the thirty-seven authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics, including: • experimental design • wildlife health and disease • capture techniques • population estimation • telemetry • vegetation analysis • conservation genetics • wildlife damage management • urban wildlife management • habitat conservation planning A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a two-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on management methodologies. The Wildlife Techniques Manual is a resource that professionals and students in wildlife biology, conservation, and management simply cannot do without.
