Emerson in His Own Time
A Biographical Chronicle of His Life, Drawn from Recollections, Interviews, and Memoirs by Family, F
Ronald A. & Joel Bosco & Myerson
University of Iowa Press, 2003
At his death, Nathaniel Hawthorne (1804–1864) was universally acknowledged in America and England as “the Great Romancer.” Novels such as The Scarlet Letter and The House of the Seven Gables and stories published in such collections as Twice-Told Tales continue to capture the minds and imaginations of readers and critics to this day. Harder to capture, however, were the character and personality of the man himself. So few of the essays that appeared in the two years after his death offered new insights into his life, art, and reputation that Hawthorne seemed fated to premature obscurity or, at least, permanent misrepresentation. This first collection of personal reminiscences by those who knew Hawthorne intimately or knew about him through reliable secondary sources rescues him from these confusions and provides the real human history behind the successful writer. 
    Remembrances from Elizabeth Peabody, Sophia Hawthorne, Oliver Wendell Holmes, Ralph Waldo Emerson, Bronson Alcott, Rebecca Harding Davis, and twenty others printed in Hawthorne in His Own Time follow him from his childhood in Salem, through his years of initial literary obscurity, his days in the Boston and Salem Custom Houses, his service as U.S. Consul to Liverpool and Manchester and his life in the Anglo-American communities at Rome and Florence, to his late years as the “Great Romancer.” 
    In their enlightening introduction, editors Ronald Bosco and Jillmarie Murphy assess the postmortem building of Hawthorne’s reputation as well as his relationship to the prominent Transcendentalists, spiritualists, Swedenborgians, and other personalities of his time. By clarifying the sentimental associations between Hawthorne’s writings and his actual personality and moving away from the critical review to the personal narrative, these artful and perceptive reminiscences tell the private and public story of a remarkable life.

Power Distribution System State Estimation

The Institution of Engineering and Technology, 2022
State estimation is a key function for real-time operation and control of electrical power systems since its role is to provide a complete, coherent, and reliable network real-time model used to set up other real-time operation and control functions. In recent years it has extended its applications to monitoring active distribution networks with distributed energy resources. The inputs of a conventional state estimator are a redundant collection of real-time measurement, load and production forecasts and a mathematical model that relates these measurements to the complex nodal voltages, which are taken as the state variables of the system. The goal of state estimation is to adjust models so that they are closer to observed values and deliver better forecasts. In power systems, this is key to maintaining power quality and operating generation and storage units well.
