When the Irish continued to rebel against English rule, the colonizers began employing methods of extreme violence to subdue the Gaelic people. At the same time, they began to practice more extreme forms of cultural colonization by attacking those aspects of Gaelic culture which most resisted conformity to English standards of civility. The Gaelic legal system, called Brehon law, redistributive inheritance, cattle herding and traditional forms of Irish dress were denigrated to assert English authority over the Irish people. English fear of the negative effects of Gaelic culture were exemplified by the Anglo-Irish lords, who were originally of English descent, but had "degenerated" into Irish barbarians through the use of Gaelic culture. This retrograde process could also occurred when an English person practiced marriage, childbirth, wet-nursing or fosterage with Irish persons. These interactions, and the consequences which came from them, were often described in terms of infection and disease. Thus culture, operating on multiple levels, and how that culture was represented, became a powerful site for colonial power to operate.
Specifically, we consider a linear parabolic PDE model that is bilinear in the robots' velocity and task-switching rates. These parameters constitute a set of time-dependent control variables that can be optimized and transmitted to the robots prior to their deployment or broadcasted in real time. The planning and allocation problem can then be formulated as a PDE-constrained optimization problem, which we solve using techniques from optimal control. Simulations of a commercial pollination scenario validate the ability of our control approach to drive a robotic swarm to achieve predefined spatial distributions of activity over a closed domain, which may contain obstacles. Secondly, we consider a mapping problem wherein a robotic swarm is deployed over a closed domain and it is necessary to reconstruct the unknown spatial distribution of a feature of interest. The ADR-based primitives result in a coefficient identification problem for the corresponding system of PDEs. To deal with the inherent ill-posedness of the problem, we frame it as an optimization problem. We validate our approach through simulations and show that reconstruction of the spatially-dependent coefficient can be achieved with considerable accuracy using temporal information alone.
Geology and its tangential studies, collectively known and referred to in this thesis as geosciences, have been paramount to the transformation and advancement of society, fundamentally changing the way we view, interact and live with the surrounding natural and built environment. It is important to recognize the value and importance of this interdisciplinary scientific field while reconciling its ties to imperial and colonizing extractive systems which have led to harmful and invasive endeavors. This intersection among geosciences, (environmental) justice studies, and decolonization is intended to promote inclusive pedagogical models through just and equitable methodologies and frameworks as to prevent further injustices and promote recognition and healing of old wounds. By utilizing decolonial frameworks and highlighting the voices of peoples from colonized and exploited landscapes, this annotated syllabus tackles the issues previously described while proposing solutions involving place-based education and the recentering of land within geoscience pedagogical models.

The ASU COVID-19 testing lab process was developed to operate as the primary testing site for all ASU staff, students, and specified external individuals. Tests are collected at various collection sites, including a walk-in site at the SDFC and various drive-up sites on campus; analysis is conducted on ASU campus and results are distributed virtually to all patients via the Health Services patient portal. The following is a literature review on past implementations of various process improvement techniques and how they can be applied to the ABCTL testing process to achieve laboratory goals. (abstract)
of nonidentical oscillators where oscillators are imbued with their own frequency and
coupled with other oscillators though a network of interactions. As the coupling
strength increases, there is a bifurcation to complete synchronization where all oscillators
move with the same frequency and show a collective rhythm. Kuramoto-like
dynamics are considered a relevant model for instabilities of the AC-power grid which
operates in synchrony under standard conditions but exhibits, in a state of failure,
segmentation of the grid into desynchronized clusters.
In this dissertation the minimum coupling strength required to ensure total frequency
synchronization in a Kuramoto system, called the critical coupling, is investigated.
For coupling strength below the critical coupling, clusters of oscillators form
where oscillators within a cluster are on average oscillating with the same long-term
frequency. A unified order parameter based approach is developed to create approximations
of the critical coupling. Some of the new approximations provide strict lower
bounds for the critical coupling. In addition, these approximations allow for predictions
of the partially synchronized clusters that emerge in the bifurcation from the
synchronized state.
Merging the order parameter approach with graph theoretical concepts leads to a
characterization of this bifurcation as a weighted graph partitioning problem on an
arbitrary networks which then leads to an optimization problem that can efficiently
estimate the partially synchronized clusters. Numerical experiments on random Kuramoto
systems show the high accuracy of these methods. An interpretation of the
methods in the context of power systems is provided.
As one of the first and most populous epicenters of the Gulag archipelago located in the Far North, from 1929-1958 Komi saw hundreds of thousands of prisoners, in addition to hundreds of thousands more who were exiled to the region from all over the Soviet Union. While some left the region after they were released, many were not able to leave or chose not to when given the choice. Regardless of where they lived when the Soviet Union collapsed, many former prisoners sent their autobiographies to branches of the Memorial Society and local history museums in Komi. For many, this was the very first time they had shared their stories with anyone. While Komi is unique in many ways, it is emblematic of processes that unfolded throughout the Soviet Union and Eastern Europe at the end of the Twentieth Century. This project expands our understanding of how civil societies form under conditions of authoritarian rule and illuminates the ways in which survivors and societies come to terms with difficult pasts.
