This book is intended for specialists in systems engineering interested in new, general techniques and for students and practitioners interested in using these techniques for solving specific practical problems. For many real-world, complex systems, it is possible to create easy-to-compute explicit analytical models instead of time-consuming computer simulations. Usually, however, analytical models are designed on a case-by-case basis, and there is a scarcity of general techniques for designing such easy-to-compute models. This book fills this gap by providing general recommendations for using analytical techniques in all stages of system design, implementation, testing, and monitoring. It also illustrates these recommendations using applications in various domains, such as more traditional engineering systems, biological systems (e.g., systems for cattle management), and medical and social-related systems (e.g., recommender systems).

Written from a practical Native American perspective by internationally recognized Chickasaw bowyer Eric Smith, this book offers a long needed introduction to not only Plains Indian bows but also arrows, quivers, and shields.

A black hole is a region of space-time exhibiting such strong gravitational effects that nothing-not even particles and electromagnetic radiation such as light-can escape from inside it. In Black Hole Factory, poet Eric Smith writes his way into and out of such holes with a commitment to the history and craftsmanship of the well-shaped poem. He compresses experience, intellect, and feeling within concentrated stanzas of compelling density, but his use of tradition, rhyme, and meter also become sources of surprise and innovation in his hands. The book has poems that communicate impressive control, intellect, and wit-poems that cultivate ironic self-awareness and detachment on the part of both poet and reader. And then there are breakthrough moments giving up both irony and control in which poet and reader experience a kind of gravitational collapse powerful enough to deform and reshape space-time. In the end, he has shaped a profound and accomplished manuscript of deep personal engagement graced by moving, open flights of lyricism.

The Reluctant Emancipator: A Study of Abraham Lincoln's Evolving Viewpoints On Liberty and its Relation to Race traces Lincoln's evolving thoughts & viewpoints on Liberty as it relates to the struggle of African Americans to achieve equal rights and equal opportunity in the United States.

I have had a love of coffee for years. I have a degree in Pharmacology-Toxicology where I ran the coffee club. Noone else wanted the responsibility to absolutely positively show up every day to make that all important fluid extraction. I learned a lot about keeping consumers happy. One time I used deionized (purified) water for the brew. I received loads of complaints. That coffee wasn't working. I hypothesize it was the lack of minerals in the water that prevented the extraction of the caffeine from the coffee grounds. Tap water worked better but needed to be de-chlorinated to improve the flavor. After graduation and years later I was again in charge of this all important job for my group with Pesticide Enforcement Branch of California Environmental Protection Agency. All went well for years until our group was moved into the main building in downtown Sacramento. I would enter the break room and see a pot half filled with "coffee" sitting on the heat being ruined. This is where I again took over coffee production.

Transit USA is a collection of personal photographs I took of urban rail lines from 1977 to 2009. This book covers my first thirty-two years of urban rail photography and has images of urban rail systems in such places as Greater New York, Chicago, Philadelphia, New Orleans, San Francisco, and Michigan City Indiana. In certain cases, these photographs contain images of transit lines and structures that no longer exist so in that sense they are a photographic record of our vanished urban landscape and provide a look into the not-too-distant past for future generations to come.

Teenager Leila's life is full of challenges. From bouncing around the foster care system to living with seasonal affective disorder, she's never had an easy road. Leila keeps herself busy with her passion for environmental advocacy, monitoring the Urban Ecovists message board and joining a local environmental club with her best friend, Sarika. And now that Leila has finally been adopted, she dares to hope her life will improve. But the voices in Leila's head are growing louder by the day. Ignoring them isn't working anymore. Something calls out to her from the grove at Fairmount Park. Is she ready to answer?

At the dawn of the 21st Century, the Chicago Elevated or "L" was in the midst of a major transition. Every elevated line had either been completely rebuilt & renovated or was about to be. Dating to 1892, Chicago's famed elevated railroads had long since fallen into disrepair and either had to be rebuilt or torn down. Between 1994 and 1996, much to the consternation of the people who used the route, the South Side and Lake Street Ls of the Green Line had been closed for extensive rebuilding and repair. When in the spring of 2000 it was determined that the West Side's Douglas L was in similar need of a rebuild, it was decided to keep the trains running while the work took place so as to avoid the public outcry that had accompanied the Lake Street and South Side Lines closings. Yet by this time the Douglas L was in too great a state of disrepair to be saved as it was; necessitating that the line be completely torn down and an entirely new structure & stations be built in its place. The photographs in this book capture the Douglas L in its final months of operation as it was as well as the beginning of its renovation. The photos in this book also document the Paulina Street Connector before it was reintegrated into the transit system as the new Pink Line and the ancient Harrison Street Curve in the final years before it was torn down and replaced. This piece is essentially a written time capsule of the Chicago "L" in transition; a brief snapshot in time when it still had one foot in the 19th Century and the other in the 21st Century. This is the Chicago "L" in those final years when it was an antiquated relic of the past; before its ornate station houses which heralded its arrival in the 1890s gave way to the wrecker's torch for the sake of progress and making the "L" into a modern day rapid transit system that is the pride of Chicago and the Midwest.

A poem told in the form of intertwined narratives from each kingdom, "The Saga of Skalheim" evokes a bleak fantasy world reminiscent of Scandinavian sagas and ancient epics: In a land once ruled by the ancient Felrothi, three kingdoms of Skalheim vie for survival and dominance. Mylians migrants built their mighty citadel Mygdol around the ruins of an abandoned Felrothi Tower. The Fror built their fortress Frorguard into the frigid mountains below the Northlands. Groups of exiles arriving from the sea settled in the south and became known as the Fen clans. Years ago, Fen warlords invaded Mygdol, leading them to form an alliance with Frorguard. The two nations defeated the Fen and negotiated a hard-won truce. However, grim fortunes now await these tribes of Skalheim. The pact between the kingdoms of Frorguard and Mygdol is fraying and the resurgent Fen seek to exploit their mutual distrust. Most ominously, each nation has begun to discover the magicks of the extinct Felrothi race.

Uniting the conceptual foundations of the physical sciences and biology, this groundbreaking multidisciplinary book explores the origin of life as a planetary process. Combining geology, geochemistry, biochemistry, microbiology, evolution and statistical physics to create an inclusive picture of the living state, the authors develop the argument that the emergence of life was a necessary cascade of non-equilibrium phase transitions that opened new channels for chemical energy flow on Earth. This full colour and logically structured book introduces the main areas of significance and provides a well-ordered and accessible introduction to multiple literatures outside the confines of disciplinary specializations, as well as including an extensive bibliography to provide context and further reading. For researchers, professionals entering the field or specialists looking for a coherent overview, this text brings together diverse perspectives to form a unified picture of the origin of life and the ongoing organization of the biosphere.
