Unmanned aerial vehicles (UAVs) are new platforms that have been increasingly used in the last few years for forestry applications that benefit from the added value of flexibility, low cost, reliability, autonomy, and capability of timely provision of high-resolution data. The main adopted image-based technologies are RGB, multispectral, and thermal infrared. LiDAR sensors are becoming commonly used to improve the estimation of relevant plant traits. In comparison with other permanent ecosystems, forests are particularly affected by climatic changes due to the longevity of the trees, and the primary objective is the conservation and protection of forests. Nevertheless, forestry and agriculture involve the cultivation of renewable raw materials, with the difference that forestry is less tied to economic aspects and this is reflected by the delay in using new monitoring technologies. The main forestry applications are aimed toward inventory of resources, map diseases, species classification, fire monitoring, and spatial gap estimation. This Special Issue focuses on new technologies (UAV and sensors) and innovative data elaboration methodologies (object recognition and machine vision) for applications in forestry.

Описание:
In order to fulfill the tremendous worldwide demand for electrification, power line professionals will need to adopt rapid, reliable and sustainable solutions. For example, in a fast-developing country like India, which had the largest population without electricity in 2014 and 1.34 billion inhabitants in 2017, the demand for electrification is immense. In recent years, a new program facilitated 0.73 million new household connections per month and almost 19,000 villages per year.
Wide-spread experience in geographical, geological, social and economic diversity leaves no doubt that overhead power lines (OHL) are the only way to provide electricity to communities where underground lines are technically unfeasible or too expensive.
This book presents the technology and recent research into OHL in a concise and systematic way.
After brief introductory sections, chapters cover line support, foundation and mechanical sag, corona discharge, overhead line insulators and conductors, earthing and earth wire, lightning and surge protection, insulation and coordination, route selection, commissioning, operation and maintenance.
This book is a must-read for researchers and experts involved with utilities and particularly for anyone associated with the installation, electrification, operation and maintenance of overhead lines in transmission and distribution networks.

Описание:
A general overview of the use of utility distribution poles, including for electric supply and communications applications
Overhead Distribution Lines: Design and Applications provides information on the design and use of power and communication distribution lines. An excellent resource for those in the power and communication utilities industry, this book presents information on the physical characteristics of utility poles, overhead supply and communication cables, installation practices, joint-usage issues, and safety rules, including the National Electrical Safety Code (NESC), California-specific rules, and others. It describes how to select the proper poles for specific applications. The especially valuable final chapter provides examples showing how it all works in practice, providing a background allowing more effective use of related industry software.
