This textbook describes the equipment, observational techniques, and analysis used in the investigation of stellar photospheres. Now in its fourth edition, the text has been thoroughly updated and revised to be more accessible to students. New figures have been added to illustrate key concepts, while diagrams have been redrawn and refreshed throughout. The book starts by developing the tools of analysis, and then demonstrates how they can be applied. Topics covered include radiation transfer, models of stellar photospheres, spectroscopic equipment, how to observe stellar spectra, and techniques for measuring stellar temperatures, radii, surface gravities, chemical composition, velocity fields, and rotation rates. Up-to-date results for real stars are included. Written for starting graduate students or advanced undergraduates, this textbook also includes a wealth of reference material useful to researchers. eBook formats include color imagery while print formats are greyscale only; a wide selection of the color images are available online.

The design of concurrent and real-time systems is difficult. It is even more difficult to design them correctly. Introduction to the Formal Design of Real Time Systems is based on the premise that in order to design things correctly it is necessary to thoroughly understand the design as it evolves from problem definition through to solution validation and, though the simplest way to maintain such an understanding is from within a formal mathematical framework, this will only be effective if the framework is simple to understand and easy to use. This book is based on courses given to undergraduate and masters students in Electrical Engineering, Information Technology and Computer Science, and backed by copious worked examples.
