A History of Marshall Academy, Marshall College and Marshall College State Normal School by Virgil A. Lewis

This history of Marshall Academy, now Marshall University, is a transcription of typescript and holograph manuscript pages written by Virgil Lewis between 1910 and 1912, while he was serving as state archivist of West Virginia. Lewis, as state archivist, had access to sources, many of which are now unavailable to researchers. Of particular note are Lewis\u27s complete transcriptions of the reports of the trustees of Marshall Academy to the Virginia Literary Fund (1839-1846), and his documentation of the years when the academy, later college, came under the control of the Methodist Episcopal Church South (1850-1858)

The Springfield Baptist Church Cemetery : An Exercise in Historical Demography

This work describes the use of three sources of data, cemetery inscriptions, vital registrations of births and deaths, and the manuscript census rolls. Consequently, it emphasizes the technique and methodology of the investigation. While the primary purpose of the study was to discover the uses and limitations of the material, observations about the sample never the less derive from the data, for the tools of historical demography can provide information about the population that becomes almost biographical in nature

Oral History Interview: Cora P. Teel

This interview is one of a series conducted concerning the history of Marshall University. Cora Teel is an archivist at Marshall University. She discusses her parents and her background, her education, Dr. Sam Clagg, Coach Cam Henderson, working on a book with Dr. Clagg, Clagg\u27s military background, his family, a committee to plan events for Marshall\u27s 150th anniversary, and President Nitzschke.https://mds.marshall.edu/oral_history/1244/thumbnail.jp

Active learning in an apparel production management course: Student perceptions, instructor training, and learning outcomes

Active learning environment was introduced to an apparel production management course. Class format was perceived as a good learning environment. Students were engaged in class material and able to understand its application to the apparel industry while gaining an increased depth of knowledge for the course content. Peer-to-peer interaction improved their learning experience in class as they shared knowledge when completing the assignment. Instructor training in active learning did have an impact on students\u27 perceptions of active learning so additional training may increase student perceptions. Learning outcomes did not increase but maintained a mean scores of 88

Lyapunov Conditions for Input-to-State Stability of Impulsive Systems

This paper introduces appropriate concepts of input-to-state stability (ISS) and integral-ISS for impulsive systems, i.e., dynamical systems that evolve according to ordinary differential equations most of the time, but occasionally exhibit discontinuities (or impulses). We provide a set of Lyapunov-based sufficient conditions for establishing these ISS properties. When the continuous dynamics are ISS but the discrete dynamics that govern the impulses are not, the impulses should not occur too frequently, which is formalized in terms of an average dwell-time (ADT) condition. Conversely, when the impulse dynamics are ISS but the continuous dynamics are not, there must not be overly long intervals between impulses, which is formalized in terms of a novel reverse ADT condition. We also investigate the cases where (i) both the continuous and discrete dynamics are ISS and (ii) one of these is ISS and the other only marginally stable for the zero input, while sharing a common Lyapunov function. In the former case we obtain a stronger notion of ISS, for which a necessary and sufficient Lyapunov characterization is available. The use of the tools developed herein is illustrated through examples from a Micro-Electro-Mechanical System (MEMS) oscillator and a problem of remote estimation over a communication network

Stability of quantized time-delay nonlinear systems: A Lyapunov-Krasowskii-functional approach

Lyapunov-Krasowskii functionals are used to design quantized control laws for nonlinear continuous-time systems in the presence of constant delays in the input. The quantized control law is implemented via hysteresis to prevent chattering. Under appropriate conditions, our analysis applies to stabilizable nonlinear systems for any value of the quantization density. The resulting quantized feedback is parametrized with respect to the quantization density. Moreover, the maximal allowable delay tolerated by the system is characterized as a function of the quantization density.Comment: 31 pages, 3 figures, to appear in Mathematics of Control, Signals, and System

An ISS Small-Gain Theorem for General Networks

We provide a generalized version of the nonlinear small-gain theorem for the case of more than two coupled input-to-state stable (ISS) systems. For this result the interconnection gains are described in a nonlinear gain matrix and the small-gain condition requires bounds on the image of this gain matrix. The condition may be interpreted as a nonlinear generalization of the requirement that the spectral radius of the gain matrix is less than one. We give some interpretations of the condition in special cases covering two subsystems, linear gains, linear systems and an associated artificial dynamical system.Comment: 26 pages, 3 figures, submitted to Mathematics of Control, Signals, and Systems (MCSS
