Microbes : Concepts and Applications (1st Edition) - Original PDF
نویسندگان: خلاصه: An accessible introduction to the world of microbes—from basic microbe biology through industrial applications Microbes affect our lives in a variety of ways—playing an important role in our health, food, agriculture, and environment. While some microbes are beneficial, others are pathogenic or opportunistic.
Thermoforming: A Plastics Processing Guide (2nd Edition) - Original PDF
نویسندگان: خلاصه: Dr. Gruenwald has indicated the desirable properties of polymerics for differing applications; thus, his text is especially useful for polymer chemists who must "tailor" plastic materials for specific groups of applications. Engineers in extruding and calendering film and sheet will benefit from the intimate relationships elucidated between processing parameters imposed upon stocks employed in thermoforming and the products thereof. Mold designers are provided with a complete guide that will enable them to avoid the less obvious pitfalls and wasted effort so often experienced in the evolution of molds for (especially) complex parts.. Quite likely, Dr. Gruenwald's suggestions willl lead to considerable benefits to those who read and practice by this remarkable exposition of thermoforming technology. Robert K. Jordan Director-Metalliding Institute, Director-Engineering Research Institute, Scientist in Residence, Gannon University
Thermoforming - Improving Process Performance - Original PDF
نویسندگان: خلاصه: This book describes the roll-fed thermoforming process, plastic materials, design of thermoformed products, thermoforming machines, trim presses, mold design, components of a complete mold system, mold layout and machine base design, mold cost estimating, knife-like trim dies, thermoforming offline punch and die trimming
Prototype and script.aculo.us: you never knew JavaScript could do this! - Original PDF
نویسندگان: خلاصه: Tired of getting swamped in the nitty-gritty of cross-browser, Web 2.0-grade JavaScript? Get back in the game with Prototype and script.aculo.us, two extremely popular JavaScript libraries, that make it a walk in the park. Be it AJAX, drag and drop, auto-completion, advanced visual effects, or many other great features, all you need is write one or two lines of script that look so good they could almost pass for Ruby code! Web applications are getting richer and richer, with more interaction baked in every day
Flight Dynamics Principles, Second Edition: A Linear Systems Approach to Aircraft Stability and Control (6th Edition) - Original PDF
نویسندگان: خلاصه: The study of flight dynamics requires a thorough understanding of the theory of the stability and control of aircraft, an appreciation of flight control systems and a comprehensive grounding in the theory of automatic control. Flight Dynamics provides all three in an accessible and student focussed text. Written for those coming to the subject for the first time the book is suitable as a complete first course text
The radar game: Understanding stealth and aircraft survivability - Original PDF
نویسندگان: خلاصه: Precision weapons and rapid targeting information mean little if aircraft are unable to survive engagements with enemy air defenses. In addition to costing the lives of pilots, high levels of attrition can ultimately affect the outcome of the theater campaign. One of the most critical factors in determining the success of an air operation is survivability. In the last several decades, the term survivability has been associated with analysis of how low observables and electronic countermeasures can help aircraft carry out their missions in hostile airspace. Discussions of survivability immediately bring to mind stealth aircraft, radar jamming and debates about the latest SA-10 threats. Yet the quest for survivability is not a fad of the Cold War or the high-technology 1990s. Its roots, and its importance to combined arms operations, go back to the first use of military aircraft in World War I.
Introduction to Communication Electronic Warfare Systems - Original PDF
نویسندگان: خلاصه: Comprehensive engineering-level resource provides you with an excellent introduction to electronic warfare (EW) for communication systems. You are provided with a complete understanding of how modern direction finders for communication signals work, along with their limitations.
