Beyond the World as Picture:Worlding and Becoming the Whole World
No full textIn his well-known essay, Die Zeit des Weltbildes, Heidegger describes modernity as the age in which the world has been reduced to a picture. The conceptualization of the world as picture is the fundamental basis of globalization and the geopolitical relations of power, inequality and exploitation that characterize the world-system created by late capitalism. The world as picture is also the basis of various conceptual approaches for understanding worldliness informing various disciplines in the humanities and the narrative social sciences: world history, globality (global exchange and intercourse) and environmental kinship. But what is implied by the world as picture is the excess that is excluded or obscured by the picture frame because the idea of a frame intimates at something that lies beyond the picture that is its ontological condition of possibility. This talk examines two philosophical accounts of what is beyond the world as picture: Heidegger’s idea of worlding and Deleuze and Guattari’s idea of becoming the whole world as it is connected to their account of minor literature. It highlights the fundamental differences between these philosophies of world and the above approaches. Time permitting, I will then explore how postcolonial world literature, when read as part of the temporal process of worlding and world-creation, disrupts and shatters the world picture by participating in struggles within specific fields of forces in contemporary globalization. Such literature unsettles their readers’ sense of territorial boundaries and makes them aware of how they are constitutively implicated in the hierarchies of the contemporary world even as it resists being arrested in a geographically bounded and determinable subject-object such as a nation, a continent or a region. Pheng Cheah is Professor in the Department of Rhetoric at UC Berkeley. His research interests include late 18th-20th century continental philosophy and contemporary critical theory, postcolonial theory and anglophone postcolonial literatures, theories of nationalism, cosmopolitanism and globalization, philosophy and literature, legal philosophy, social and political thought, and feminist theory. He is the author of What Is a World? On Postcolonial Literature as World Literature (2016), Inhuman Conditions: On Cosmopolitanism and Human Rights (2006), and Spectral Nationality: Passages of Freedom from Kant to Postcolonial Literatures of Liberation (2003). Followed by a discussion with Pheng Cheah (UC Berkeley), Carmen Moersch (Kunsthochschule Mainz) and Birgit Hopfener (Carleton University) Moderated by Monica Juneja (Heidelberg University
Development of an ankle exoskeleton system
No full textIn the recent decades, there have been more research and development (R & D) on exoskeletons. An exoskeleton is an external robotic suit, donned by the user, which can either increase the user’s speed or track the user’s motion while carrying an external load. Exoskeleton R & D has been gaining popularity due to its wide range of application and improvements in enabling technology (for e.g. improved energy density of batteries). One of the applications is in the military, where the exoskeleton is used primarily to enhance the speed of the soldier or improve their endurance by helping to support the load of the soldier. This project was initiated by the author himself and was done with the direct supervision of his supervisor, Assoc Prof. Cheah Chien Chern. The objective of the project is to develop an ankle exoskeleton which tracks the user’s ankle motion via sensing of the user’s intention through the measurement of the user’s heel contact force. This report discusses the process of developing the ankle exoskeleton from scratch, from the design of hardware to the testing and implementation of the controller. Key phases of the project are hardware phase, software and electronics phase and the controller design phase. The final ankle exoskeleton was able to track the user’s ankle motion while the user oscillates his ankle, up to a maximum speed of 0.714Hz without impeding the user’s motion.Bachelor of Engineerin

Remote sensing reflectance measured in the South China Sea and Sulu Sea during RV Sonne cruise SO218 from 18 to 27 November 2011
No full textWe present a data set on remote sensing reflectance (RRS) at 1nm resolution from 350 to 800nm obtained from measurements in the coastal and open ocean areas of the South China Sea and Sulu Sea from 18 to 27 November 2011. For the measurements we used radiometric hyperspectral (3.3 nm sampling, 10 nm FWHM) underwater profile measurements down to the 0.1 % light level using RAMSES (TriOS GmbH, Germany) sensors which measured depth resolved the upwelling radiance and downwelling irradiance, both corrected by incident sunlight fluctuations with a second RAMSES sensor measuring the above water downwelling irradiance. The later sensor data were also used to finally calculate RRS.
We followed the protocol by Mueller et al. (2003) further modified by Matsuoka et al. (2007) and Stramski et al. (2008), as described for our instrument set-up in Taylor et al. (2011). Our method is further described and assessed for its uncertainty in Tilstone et al. (2020). The campaign is described in detail in Cheah et al. (2013) and was also optical constituents hyperspectral absorption data (Bracher et al. 2021a, b) and phytoplankton pigments (Bracher 2014) were measured

An Activity Led Learning Approach as a pedagogy in teaching Digital Forensics
No full textDigital Forensics, as a subject of academic study, has been evolving over its relatively short life span in a number of academic institutions. As such the pedagogy associated with it is an area which is relatively ill-defined and lacking in clear best practise or even consensus on the manner of its delivery. The educational concept of "constructive alignment" has been identified as having particular relevance in seeking the effective delivery of teaching and learning in digital forensics. The issues that create challenges in this domain relate to achieving forensically sound evidence and understanding its legislative context for generally technically competent students. This paper seeks to catalogue the methodology used at Postgraduate level, in respect of the teaching of Digital Forensics at Coventry University. In particular it identified the development of a new Network and Mobile Device Forensics Module as part of the MSc Forensic Computing programme. As such the mode of delivery, utilisation of laboratory time, assessment criteria and statistical validation of the approach will be evidenced and demonstrated.7th International conference on Cybercrime Forensics Education and Training (CFET), At Canterbury Christ Church Universit

An essential role for MCL-1 in ATR-mediated CHK1 phosphorylation
No full textHere we report a novel role for myeloid cell leukemia 1 (Mcl-1), a Bcl-2 family member, in regulating phosphorylation and activation of DNA damage checkpoint kinase, Chk1. Increased expression of nuclear Mcl-1 and/or a previously reported short nuclear form of Mcl-1, snMcl-1, was observed in response to treatment with low concentrations of etoposide or low doses of UV irradiation. We showed that after etoposide treatment, Mcl-1 could coimmunoprecipitate with the regulatory kinase, Chk1. Chk1 is a known regulator of DNA damage response, and its phosphorylation is associated with activation of the kinase. Transient transfection with Mcl-1 resulted in an increase in the expression of phospho-Ser345 Chk1, in the absence of any evidence of DNA damage, and accumulation of cells in G2. Importantly, knockdown of Mcl-1 expression abolished Chk1 phosphorylation in response to DNA damage. Mcl-1 could induce Chk1 phosphorylation in ATM-negative (ataxia telangectasia mutated) cells, but this response was lost in ATR (AT mutated and Rad3 related)-defective cells. Low levels of UV treatment also caused transient increases in Mcl-1 levels and an ATR-dependent phosphorylation of Chk1. Together, our results strongly support an essential regulatory role for Mcl-1, perhaps acting as an adaptor protein, in controlling the ATR-mediated regulation of Chk1 phosphorylation.Peer reviewedfinal article publishe

Cold gas microthruster
No full textThis chapter covers the development of cold gas microthruster, which is widely regarded as the simplest way of generating thrust in space, for nanosatellites. A brief background and principles of operation were given, followed by the introduction of nozzle theory that could be used in the preliminary estimation of microthruster performance and considerations in selecting a suitable propellant. The current state of development in cold gas microthruster (at the time of writing in 2020) was provided, from its first use in SNAP-1 in 2000 to another 12 nanosatellites as well as one technology demonstration mission in Prototype Research Instruments and Space Mission technology Advancement small satellite. The chapter ends with a discussion on future nanosatellite missions that will feature a cold gas microthruster system and the challenges, such as fabrication of micronozzle and its design optimization, to improve overall efficiency.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Space Systems Egineerin
