What is known about the lives, and especially the private lives, of English women in the early modern era is not at all satisfactory in terms of sources, scope, or understanding. Because the act of writing and reading was already exclusive to the upper classes, what sources do survive are not representative of the majority of the female population, leading to more speculation on behalf of historians. The sources which do survive, by and large focus on the role of religion and spirituality in a woman's life, since it was the most acceptable reason for an early modern woman to be writing about. However, I hoped to prove how women were interested in more than just self-improvement through religious devotion, thereby demonstrating that early modern English women were as complex and rich in personality and interests as a modern woman might consider herself to be. After a brief introduction and explanation of the research process, this project then begins to individually analyze the three women who were chosen for study based on their mutual practice of keeping a diary during their lives in early modern England. These women were Elizabeth Freke, Lady Sarah Cowper, and Mary, Countess Cowper, all of whom operated within the feminine social hierarchy during this period, but each of whom demonstrated a particular interest beyond that of marriage and family, including economics, religion, and politics. I believe that each woman analyzed proved how unique and varied the lives of early modern English women were through their writings.

The goal of this research is to couple a physics-based model with adaptive algorithms to develop a more accurate and robust technique for structural health monitoring (SHM) in composite structures. The purpose of SHM is to localize and detect damage in structures, which has broad applications to improvements in aerospace technology. This technique employs PZT transducers to actuate and collect guided Lamb wave signals. Matching pursuit decomposition (MPD) is used to decompose the signal into a cross-term free time-frequency relation. This decoupling of time and frequency facilitates the calculation of a signal's time-of-flight along a path between an actuator and sensor. Using the time-of-flights, comparisons can be made between similar composite structures to find damaged regions by examining differences in the time of flight for each path between PZTs, with respect to direction. Relatively large differences in time-of-flight indicate the presence of new or more significant damage, which can be verified using a physics-based approach. Wave propagation modeling is used to implement a physics based approach to this method, which is coupled with adaptive algorithms that take into account currently existing damage to a composite structure. Previous SHM techniques for composite structures rely on the assumption that the composite is initially free of all damage on both a macro and micro-scale, which is never the case due to the inherent introduction of material defects in its fabrication. This method provides a novel technique for investigating the presence and nature of damage in composite structures. Further investigation into the technique can be done by testing structures with different sizes of damage and investigating the effects of different operating temperatures on this SHM system.
