This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system. In the same position we find the woman. She is the very epicentre of the novel and the violence directed towards her is part of a complex problem that I adress. The woman is divided into pieces and fetischized by the male gaze to serve as a solution for his trauma. Hal Foster's notion ”the double logic of prosthesis” constitutes a theoretical base. The model shows how a fetischistic strategy is applied by avant-garde artists to solve the technological trauma that they experience. Both content and composition of The Atrocity Exhibition are inspired by avant-garde practices, I have therefore compared the text with Foster's theory on how the avant-garde problematized the interaction between man and machine. Marshall McLuhan's belief that the human body and technology are inseparable in the era of electronics further helps me to study technology's effect on perception.

Iron and aluminium hydroxides were the most abundant precipitate complexes that formed in the HAL circuit. Sulphates formed bridges with the iron complexes. It was found that precipitation of iron in the HAL circuit was a function of the pH, ferric ion concentration and temperature of the process water. Experimental work provided abundant evidence that the precipitated iron hydroxide and other species adsorb to the surfaces of zircon and rutile mineral particles due to opposite zeta potentials of the mineral particles and iron hydroxide. These adsorbed species altered the electrostatic potential of the mineral surfaces, which reduced the electrostatic separation efficiency of these minerals. It was determined that an improvement of 7% could be expected if the precipitation and attachment of iron could be minimised. Based on the experimental results, conceptual processes were developed and iterative simulations were set up to determine the optimum solution that would maximise the removal of dissolved iron. This solution would ensure clean mineral surfaces free of any adsorbed precipitates. This process circuit was constructed in May to August 2004 at a total capital cost of R4.8m and removed 99.97% of the total dissolved iron prior to caustic addition. Prime zircon recoveries were increased by 3-7%. / AFRIKAANSE OPSOMMING: Hierdie studie het wetenskaplike bewyse gelewer dat yster en ander spesies neerslae vorm in die HAL proses van die Mineraal Skeidings Aanleg van Namakwa Sands. Yster- en aluminium hidroksiede was die vernaamste neerslag komplekse wat gevorm het in die HAL proses. Sulfaat spesies het verbindings gevorm met die yster komplekse. Die neerslag van yster was ‘n funksie van pH, ferric ioon konsentrasie en temperatuur van die proses water. Eksperimentele werk het genoegsame bewyse gelewer dat die yster hidroksied neerslag en ander spesies adsorbeer op die oppervlaktes van sirkoon en rutiel minerale weens teenoorgestelde zeta potensiale van die mineraal partikels en yster hidroksiede. Hierdie geadsorbeerde spesies het die elektrostatiese potentiaal van die mineraal oppervlaktes verander wat sodoende die elektrostatiese skeidingsvermoë van hierdie minerale verminder het. ‘n Verbetering van 7% in elektrostatiese skeiding van sirkoon en rutiel minerale kan verwag word indien die neerslag en adsorbsie van yster minimiseer word. Konseptuele prosesse, gebasseer op die eksperimentele resultate, is ontwikkel. Itteratiewe simulasies is opgestel om die optimum proses te bepaal wat sodoende die maksimum verwydering van die opgeloste yster sou verseker. Hierdie oplossing sou skoon mineraal oppervlaktes, vry van enige geadsorbeerde neerslae, verseker. Hierdie prosesaanleg was opgerig in Mei tot Augustus 2004 teen ‘n kapitaalkoste van R4.8m en dit het 99.97% van die totale opgeloste yster verwyder voordat natrium hidroksied bygevoeg is. Primêre sirkoon opbrengste het sodoende toegeneem met 3-7%.

The goal of this research was to determine if the results of a simple comparison algorithm (SCA) could be improved by adding a hyperspace analogue to language model of memory (HAL) layer to form NCA. The HAL layer provides contextual data that otherwise would be unavailable for consideration. It was found that NCA did improve the results when compared to SCA alone. However, NCA added complexity problems that limit its practicality. The complexity of this algorithm is On3 where n is equal to the number of unique symbols in the data. While there is a relativity reasonable soft upper bound for the number of unique symbols used in a language, the complexity still limits the uses of the NCA combined algorithm. The conclusion from this research is that NCA can improve results. This research also suggested that the quality of results might increase as more data is processed by NCA.

Recent scholarship has explored the “Machiavellian” actions of Prince Hal in Henry IV, Part 1 ; yet the classical rhetorical pedagogy of Renaissance Britain suggests that the speeches in the play lead to a transformation in Hal that is antithetical to the emergent understanding of Hal as a great manipulator. Falstaff uses the ruse of rhetoric instructor in order to construct a classical rhetorical argument for his own ends, and Henry IV gives a passionate yet formally adept (and classically rhetorical) plea to his son in order to incite change. An analysis of Falstaff and Henry’s arguments as well as Hal’s responses provides the framework of understanding the play not as an example of what has been called “Machiavellianism” but rather as a testament to the power of what Cicero calls the "good man skilled in speaking.”

This thesis presents the design and implementation of a multifunctional radar sensor. Utilising microstrip transmission line technology, a front-end receiver has been designed based upon a six-port architecture. Additionally, digital signal processing has been implemented on a microcontroller, enabling processing and extraction of information from the down converted quadrature signals. Results have show that the sensor is capable of operating as both a continuous wave radar and frequency modulated continuous wave radar. Through measurements, it has been established that the sensor is capable of wireless measurements, such as vital signs and vibrations. Furthermore, a graphical user interface has been design, allowing a way of switching between different radar configurations and the presentation of measured data to the user.

Les biocapteurs constituent un défi pour le diagnostic médical, la surveillance des eaux naturelles ...Dans ce travail, nous avons défini les conditions de précipitation de la structure Hôte par hydrolyse thermique de l'urée. Une nouvelle voie de synthèse d'HDL a été mise au point, utilisant la décomposition catalytique de l'urée par l'uréase. Une étude comparative des procédés d'immobilisation a permis de maîtriser la formation du matériau hybride et de contrôler la quantité d'uréase immobilisée, dont l'activité catalytique a été étudiée. L'élaboration des biocapteurs sous forme de multicouches nanostructurées HDL-Uréase a été réalisée par la technique Langmuir-Blodgett, et leur réponse a été évaluée. Cette première étude sur le confinement de protéines sur des matrices HDL, depuis l'élaboration de la matrice hôte jusqu'à la réalisation du biocapteur fonctionnel, ouvre des perspectives sur l'immobilisation d'autres enzymes et l'optimisation de films hybrides à propriétés biologiques
