Anvendt elektroteknik – forsyningsanlæg til elektriske installationer er en lærebog, der retter sig mod studerende, som ønsker at opnå kompetencer inden for højspændingsteknik. Bogen har særlig fokus på, at læseren får et overblik og kan se den systematik, der er fælles for transmissionsnettet og distributionsnettet. Anvendt elektroteknik – forsyningsanlæg til elektriske installationer gør sig fri af specifikke typer effektafbrydere og behandler mere generelle indstillinger. Bogen benytter impedansmetoden, der er en enkel metode og sikker nok til at foretage beregninger af kortslutningerne på 10 kV eller 20 kV niveau, samt på lavspændingsnettet. Bogen er målrettet de videregående tekniske uddannelser, især elinstallatøruddannelsen og maskinmesteruddannelsen, men kan også anvendes som håndbog af elrådgivere. Bogen er tillige rettet mod at opnå læringsmål svarende til el-autorisationsprøvens første opgave. Den er skrevet som et værktøj, der øger analyseniveauet hos de teknikere, elektrikere og el-ansvarligere, der arbejder med sikkerhed i elinstallationer, som er påvirket af højspændingsnettet.

The earlier editions of this title have been best-selling definitive references for those needing technical information about automotive fuels. This long-awaited latest edition has been thoroughly revised and updated, yet retains the original fundamental fuels information that readers find so useful.This book is written for those with an interest in or a need to understand automotive fuels. Because automotive fuels can no longer be developed in isolation from the engines that will convert the fuel into the power necessary to drive our automobiles, knowledge of automotive fuels will also be essential to those working with automotive engines.Small quantities of fuel additives increasingly play an important role in bridging the gap that often exists between fuel that can easily be produced and fuel that is needed by the ever-more sophisticated automotive engine. This book pulls together in a single, extensively referenced volume, the three different but related topics of automotive fuels, fuel additives, and engines, and shows how all three areas work together.It includes a brief history of automotive fuels development, followed by chapters on automotive fuels manufacture from crude oil and other fossil sources. One chapter is dedicated to the manufacture of automotive fuels and fuel blending components from renewable sources, including e-fuels. The safe handling, transport, and storage of fuels, from all sources, are covered.New combustion systems to achieve reduced emissions and increased efficiency are discussed, and the way in which the fuels' physical and chemical characteristics affect these combustion processes and the emissions produced are included. As CO2 is now an important emission there is also discussion regarding low and non-carbon fuels and how they might be used.There is also discussion on engine fuel system development and how these different systems affect the corresponding fuel requirements. Because the book is for a global market, fuel system technologies that only exist in the legacy fleet in some markets are included. The way in which fuel requirements are developed and specified is discussed. This covers test methods from simple laboratory bench tests, through engine testing, and long-term test procedures.

This book presents the latest accomplishments in Novikov/conformal gearing as well as high-conformal gearing.  It is focused primarily on strength calculation of gear teeth and the manufacturing of gears for Novikov/conformal and high-conformal gearing along with a brief discussion of achievements in the modern theory of gearing. The modern theory of gearing is the foundation of all optimal designs of gears, gear-sets, and transmissions of all known designs, as well as, of all those to be developed in the future. As even a small improvement in efficiency on a single gear can represent a significant cost saving, given the millions of gears used in industry every year, this volume provides the design and manufacturing engineer in invaluable resource.

This textbook aimed at upper-level undergraduate and graduate engineering students who need to describe the large deformation of elastic materials like soft plastics, rubber, and biological materials.  The classical approaches to finite deformations of elastic materials describe a dozen or more measures of stress and strain.  These classical approaches require an in-depth knowledge of tensor analysis and provide little instruction as to how to relate the derived equations to the materials to be described.  This text, by contrast, introduces only one strain measure and one stress measure.  No tensor analysis is required.  The theory is applied by showing how to measure material properties and to perform computer simulations for both isotropic and anisotropic materials.  The theory can be covered in one chapter for students familiar with Euler-Lagrange techniques, but is also introduced more slowly in several chapters for students not familiar with these techniques.  The connection to linear elasticity is provided along with a comparison of this approach to classical elasticity.

This book is aimed to provide comprehensive and systematic knowledge of kinematic synthesis as developed up to date. Modern mechanical systems require advance kinematics knowledge to support mechanism design with sound theories and methods. The book includes not only the classical foundations of kinematic synthesis, but also the latest advances developed by the authors. Moreover, many examples are included to illustrate both methods and their supporting theory.The focus is on systems of rigid bodies forming closed loops. The four-bar linkage, representing the foundations of mechanical systems,  is given due attention, in its three domains: planar, spherical, and spatial. The book contains six chapters, the first two covering fundamentals for kinematic synthesis, including qualitative synthesis. Chapters 3-5 describe, in full detail,  the function, motion, and path syntheses of single-dof linkages.  In the last chapter, the synthesis of single-dof complex linkages, including six-bar and ten-bar linkages, is introduced.The book is suitable for graduate students of mechanical engineering, researchers of mechanism and robot design, and machine design engineers.

This book contributes to the navigation algorithm development for an autonomous mobile orchard robot in a GNSS denied environment. In this book, an approach is provided for path planning in an orchard using an aerial view of the environment by creating Binary Occupancy Grid Maps. The path planning is further implemented by the Probabilistic Road Maps Method (PRM) over the developed Binary Occupancy Grid Maps. For robot¿s navigation, a navigation model is developed using kinematic equations of the robot. Further, the navigation module is used in conjunction with the path-planning module. The robot was tested successfully both in simulation as well as in the real environment.

Estimating evapotranspiration (ET) has been one of the most critical research areas in agriculture because of water scarcity, the growing population, and climate change. The accurate estimation and mapping of ET are necessary for crop water management. Traditionally, researchers use water balance, soil moisture, weighing lysimeters, or an energy balance approach, such as Bowen ratio or eddy covariance towers to estimate ET. However, these ET methods are point-specific or area-weighted measurements and cannot be extended to a large scale. On the other hand, while remote sensing is able to provide spatially distributed measurements, the spatial resolution of multispectral satellite images is often not enough for crops with clumped canopy structures, such as trees and vines. Unmanned aerial vehicles (UAVs) can mitigate these spatial and temporal limitations. Lightweight cameras and sensors can be mounted on the UAVs and take high-resolution images. Unlike satellite imagery, the spatial resolution of the UAV images can be at the centimeter-level. UAVs can also fly on-demand, which provides high temporal imagery. This book examines the different UAV-based approaches of ET estimation. Models and algorithms, such as mapping evapotranspiration at high resolution with internalized calibration (METRIC), the two-source energy balance (TSEB) model, and machine learning (ML) are discussed. It also covers the challenges and opportunities for UAVs in ET estimation, with the final chapters devoted to new ET estimation methods and their potential applications for future research.
