AI Enhanced Control Engineering Methods
AI and machine learning based approaches are becoming ubiquitous in almost
all engineering fields. Control engineering cannot escape this trend. In this
paper, we explore how AI tools can be useful in control applications. The core
tool we focus on is automatic differentiation. Two immediate applications are
linearization of system dynamics for local stability analysis or for state
estimation using Kalman filters. We also explore other usages such as
conversion of differential algebraic equations to ordinary differential
equations for control design. In addition, we explore the use of machine
learning models for global parameterizations of state vectors and control
inputs in model predictive control applications. For each considered use case,
we give examples and results
Trauma as counter-revolutionary colonisation: narratives from (post)revolutionary Egypt
We argue that multiple levels of trauma were present in Egypt before, during and after the 2011 revolution. Individual, social and political trauma constitute a triangle of traumatisation which was strategically employed by the Egyptian counter-revolutionary forces â primarily the army and the leadership of the Muslim Brotherhood â to maintain their political and economic power over and above the social, economic and political interests of others. Through the destruction of physical bodies, the fragmentation and polarisation of social relations and the violent closure of the newly emerged political public sphere, these actors actively repressed the potential for creative and revolutionary transformation. To better understand this multi-layered notion of trauma, we turn to Habermasâ âcolonisation of the lifeworldâ thesis which offers a critical lens through which to examine the wider political and economic structures and context in which trauma occurred as well as its effects on the personal, social and political realms. In doing so, we develop a novel conception of trauma that acknowledges individual, social and political dimensions. We apply this conceptual framing to empirical narratives of trauma in Egyptâs pre- and post-revolutionary phases, thus both developing a non-Western application of Habermasâ framework and revealing ethnographic accounts of the revolution by activists in Cairo
Oranges and Sunshine: The Story of a Traumatic Encounter
This paper will rely on some well-known theories on trauma, memory and ethics to study how Jim Loachâs debut film Oranges and Sunshine (2010) testifies to the traumatic deportation of up to 150,000 British children to distant parts of the Empire, mainly Australia, until 1970. Oranges and Sunshine was based on Margaret Humphreysâ moving memoir, originally entitled Empty Cradles (1994) but later re-titled Oranges and Sunshine after Loachâs film. What these two texts basically claim is the need to recover historic memory through heart-breaking acts of remembrance, which can alone denounce the atrocities that were concomitant with the colonial enterprise and pave the way for disclosing and working through individual and collective traumas
Remembering trauma: Fugard's The Train Driver
Among Fugard's post-apartheid plays one escapes the sentimental nostalgia of his recent turn inwards - The Train Driver (2010). In it he develops a challenging sense of the country's dealings with the past by focusing on the remembering of a 'track suicide' by the white driver, whose tragic story is told by a black gravedigger. The driver's morbidly excessive reaction, the result of identifying with the victim whose grave he seeks, is balanced in performance by the sympathy and acceptance of the gravedigger. The squatter camp cemetery setting provides a liminal urban space stressing the continuity of past wrongs while the selective remembering of the nation's elite masks everyday poverty and violence
