Bird Feeding Basics
Bird Feeding Basics is a simplified introduction to attracting and identifying North America's most common backyard birds. Subjects covered include feeder selection, the types of feeder foods that attract certain species, and how to make your backyard more bird-friendly by providing water, shelter, food and plants that provide birds with food during each season and safe places to nest. In addition, it features beautiful illustrations of more than 50 common species. This convenient guide is an ideal, portable source of practical information and ideal for field use. Made in the USA.
Birds, Scythes And Combines
First published in 2003, Birds, Scythes and Combines provides an historical perspective to changes in farmland bird populations in Britain over the past 250 years. Despite the scale of change in habitats and agricultural methods in the late eighteenth and nineteenth centuries, early avifaunas show that farmland birds were little affected. Specialised species of fen and marsh were lost, often as much to persecution as habitat destruction, but farmland birds benefited from the appearance of extensive new resources which aided their adaptation to the altered habitats created by the new farming methods. In addition, many old permanent grass habitats were little altered, leaving a major reservoir of important habitats unchanged. By contrast, more modern farming methods, with changes in grassland management, in herbicide use and in harvesting methods particularly, have led to a collapse in the diversity of farmland and a consequent steep decline in the population size of a high proportion of farmland birds.
Feedback Control Systems
Feedback Control Systems: A Fast Track Guide for Scientists and Engineers is an essential reference tool for: Electrical, mechanical and aerospace engineers who are developing or improving products, with a need to use feedback control systems. Faculty and graduate students in the fields of engineering and experimental science (e.g., physics) who are building their own high-performance measuring/test arrangements. Faculties teaching laboratory courses in engineering and measurement techniques, and the students taking those courses. Practising engineers, scientists, and students who need a quick intuitive education in the issues related to feedback control systems. Key features of Feedback Control Systems:
From the reviewers: Control systems are ubiquitous and their use would be even more widespread if more people were competent in designing them. This book will play a valuable role in expanding the cadre of competent designers. This is a book that needed to be written, and its presentation is different from any other book on controls intended for a wide community of engineers and scientists. The book breaks the common cliche of style in the control literature that tends toward mathematical formality. Instead, the emphasis is on intuition and practical advice. The book contains a very valuable and novel heuristic treatment of the subject. .. one of the best examples of a book that describes the design cycle. The book will help satisfy the demand among practising engineers for a good introduction to control systems.
- The contents and the layout of the book are structured to ensure satisfactory proficiency for the novice designer.
- The authors provide the reader with a simple yet powerful method for designing control systems using several sensors or actuators.
- It offers a comprehensive control system troubleshooting and performance testing guide.
