Probes for measuring noise current in an electronic cable

Electromagnetic interference in deep-space network receiver is often caused by stray coupling from power lines. These stray signals create potential differences between ground terminals, which leads to excessive noise in receiver circuits. Pair of probes detect and measure noise currents in conductors

Means for mapping radiated fields and for measuring differential movement of antenna elements

Null seeking system uses two transponders located at selected points on dish to detect phase-front of received signal. One signal line has continuously variable phase shifter driven by reversible stepmotor. Each of two transponders on dish is a dipole with mixer crystal between elements. Crystal is driven, in turn, by 181.6MHz signal carried by miniature coaxial cable

Emission tester for high-power vacuum tubes

A simple emission-testing circuit for high power vacuum tubes to check their output stability is described. With modification it may be useful in testing mercury-arc rectifiers

Why wasn’t capitalism born in China?: Deleuze and the philosophy of non-events

In this paper, I will address Deleuze and Guattari’s consideration of capitalism’s aborted birth in China by approaching the problematic from within their philosophy of history. To begin with, I will set out Deleuze and Guattari’s immediate answer, canvassing their machinic ontology and the significance that they place on immanence to the emergence of capitalism. In doing so, the question of history and historical interpretation will be raised. Following, I will investigate the status of such questions and inquire as to why Deleuze and Guattari ontinually pose them. From this analysis I will suggest that a critical philosophy of non-events can be found in Deleuze and Guattari’s work that is related to but distinct from their philosophy of the Event

The necessity and contingency of universal history: Deleuze and Guattari contra Hegel

History occupies a somewhat awkward position in the work of Gilles Deleuze and Félix Guattari. Although they often criticise history as a practice and advance alternatives that are explicitly anti-historical, such as 'nomadology' and 'geophilosophy', their scholarship is nevertheless littered with historical encounters and deeply influenced by historians such as Fernand Braudel. One of Deleuze and Guattari's more significant engagements with history occurs through their reading and theory of universal history. In this paper I will explicate and critically analyse the nature of this universal history vis-à-vis its most pertinent counterpoint: Hegel's philosophy of world history. In con- trast to Hegel’s form of historicism, which universalizes by virtue of a unitary and totalizing force, Deleuze and Guattari develop a universalizing mechanism that is strictly devoid of any privileged essence. Following, Deleuze and Guattari's form of universal history is marked above all by contingency as opposed to necessity. In this paper I will show precisely how. I will also go on to demonstrate how Deleuze and Guattari's universal history offers the promise of an historical ontology commensurate with the processes of creativity and becoming, provided that appropriate steps are taken to reaffirm the radical contingency at its heart

From structuralism to poststructuralism

As the immediate precursor to poststructuralism, the movement or paradigm of structuralism was naturally responsible for determining many of poststructuralism’s salient features. But what was structuralism, and how are we to understand its transformation into poststructuralism? In this chapter I will address these issues by first outlining the contours of what might be called the image of structuralism. An appreciation of this image is necessary for a full understanding of the shift from structuralism to poststructuralism. Nevertheless, an acknowledgement of its limitations, of the inconsistencies it suppresses and the inaccuracies it perpetrates, is equally necessary. As I will therefore demonstrate, alongside the formation and propagation of the classical structuralist image runs a history of its transformation – a history of those aspects and individuals who subverted the image of structuralism in one way or other, as it was in the process of emerging

Emerging from the depths: on the intensive creativity of historical events

This paper will explore the possibility of a creative philosophy of history in the work of Gilles Deleuze. It will do so by focusing on Deleuze’s concepts of ‘intensity’ and ‘depth’, as discussed in his seminal work Difference and Repetition. By analysing these concepts in light of several historical thinkers whom Deleuze significantly draws upon (Bergson, Péguy and Braudel), I will show in this paper how Deleuze promotes a theory of history that is not opposed to his philosophy of becoming and creativity, but in concert with it
