La pulsion invocante traverse l’oeuvre de Jacques Lacan, bien qu’il n’ait jamais vraiment développé ce thème : son objet est la voix, au moment même où cette dernière fait défaut : notre hypothèse est que le sujet passe à l’acte au moment où la voix se tait, il n’y a pas de cogito. Intriquée à la pulsion scopique, la pulsion invocante a pour signature le silence. Le passage à l’acte procède d’un « je ne pense pas », du langage et non des affects que le sujet subirait. Cette thèse envisage la dimension réelle du père dans le passage à l’acte, en cas de décompensation psychotique, dans son rapport à la pulsion invocante. Des lois ont été établies pour différencier les actes des sujets désignés fous, psychotiques, de ceux des autres pauvres, faibles et criminels, ce qui précise le cadre de l’expertise mentale qui n’est pas étranger à notre recherche. Les textes des lois de 1838 et de 1990 ont été modifiés non tant pour assurer une meilleure protection des patients que pour des raisons sécuritaires. Ainsi, les différents modes d’hospitalisation ont été révisés : hospitalisation libre, hospitalisation à la demande d’un tiers (HDT), hospitalisation d’office (HO) … jusqu’à la notion récente de soins sous contrainte. Notre thèse commence par revisiter ces aspects historiques pour situer le contexte des passages à l’acte qui seront ensuite analysés à la lumière de l’enseignement de Lacan. Nous envisageons la voix comme une tentative de substitution à la forclusion duNom du Père, la voix venant suppléer et compléter le silence de l’Autre. Pour ce faire, nous développons plusieurs illustrations cliniques. Dans le cas de Juan, nous montrons comment le travail thérapeutique lui a permis de ne pas entrer dans le silence et de rechercher son nom en s’adressant à nous. Le travail de la parole empêche le passage à l’acte. Le roman de Duras, La pluie d’été, permet d’entendre la pulsion invocante comme l’écho de la voix de l’Autre et sa résonance corporelle. Avec Seth, la voix du père et celle du diable se confondent, pacte d’alliance entre les pères terribles interdicteurs et les figures féminines. Avec Mme X, nous approchons mieux les aspects de la formule de Lacan : dans la psychose, la voix sonorise le regard. Nous pouvons ensuite prendre la mesure de ce qui se passe pour Chris qui ne supporte pas la voix. La question de l’envers de l’auto-punition est abordée avec la patiente Médée. Nous prenons alors appui sur Gabriel Garcia Marquez avec chronique d’une tentative mortifère annoncée. Nous tentons enfin de comprendre le déclenchement de la psychose chez Telfusa, que les voix selon ses dires accompagnent constamment, même quand elle parle. Le traitement se présentera ainsi : non à Juana la folle mais oui à la liberté. Cette thèse tente de mettre en évidence la valeur propre à la parole introduite par la psychanalyse en éclairant la clinique de l’acte dans le champ des psychoses. / The invocative drive goes through the work of Jacques Lacan, although he never really developed this theme: its object is the voice, at the very moment when it is lacking: our hypothesis is that the subject passes to the act when the voice is silenced, there is no cogito. Intricate to the scopic drive, the invocative drive has the silence as a signature. The passage to the act proceeds from a "I do not think", from language and not from affects that the subject would suffer. This thesis considers the dimension of real of the father in the passage to the act, in a psychotic decompensation case, in his relation to the invocative drive. Laws have been established to differentiate the actions of the designated as crazy, psychotic subjects from those of the poor, weak and criminals, which specifies the framework of mental expertise that is not foreign to our research. The texts of the laws of 1838 and 1990 were modified not so much to ensure a better protection of the patients as for security reasons. Thus, the various modes of hospitalization were revised: free hospitalization, hospitalization at the request of a third party, duty of hospitalization ... until the recent concept of duty of care. Our thesis begins by revisiting these historical aspects to situate the context of passage to the act which will then be analyzed in the light of Lacan's teaching. We envision the voice as a tentative to substitute for the foreclosure of the Name of the Father, the voice supplies and completes the silence of the Other. To do this, we develop several clinical illustrations. In the case of Juan, we show how the therapeutic work allowed him not to go into silence and look for his name by addressing to us. The work of speech prevents the passage to the act. Duras' novel, Summer Rain, allows us to hear the invocative drive as the echo of the voice of the Other and its bodily resonance. With Seth, the voice of the father and the devil are confused, a pact of alliance between the terrible interdicting fathers and the female figures. With Mrs. X, we are getting closer to the aspects of Lacan's formula: in psychosis, the gaze sounds. We can then take inconsideration what happened to Chris who cannot stand the voice. The question of the reverse side of self-punishment is discussed with the patient Medea. We then rely on Gabriel Garcia Marquez with a chronic of a deadly attempt announced. Finally, we try to understand the outbreak of psychosis in Telfusa, whom the voices according to her constantly accompany her, even when she speaks. The treatment will be like this: no to Juana the Crazy but yes to freedom. This thesis attempts to highlight the proper value of the word introduced by psychoanalysis, by illuminating the clinical practice of the passage to the act in the field of psychosis. / La pulsion invocante atraviesa la obra de Jacques Lacan, aunque él nunca desarrolló realmente este tema: su objeto es la voz, en el momento mismo en que ella falta: nuestra hipótesis es que el sujeto pasa al acto cuando la voz se calla, no hay cogito. Intrincada a la pulsión escópica, la pulsión invocante tiene como firma, el silencio. El pasaje al acto procede de un "yo no ienso", del lenguaje, y no de un afecto del cual sufriría el sujeto. Esta tesis considera la dimensión real del padre en el pasaje al acto, en caso de descompensación psicótica, en su relación con la pulsión invocante. Se han establecido leyes para diferenciar los actos de los sujetos designados como locos, psicóticos de los actos de los pobres, débiles y criminales lo que especifica el marco de peritaje psicológico que no es ajeno a nuestra investigación. Los textos de las leyes de 1838 y 1990 se modificaron no tanto para garantizar una mejor protección de los pacientes como por razones de seguridad. Por lo tanto, se revisaron los diversos modos de hospitalización: hospitalización libre, hospitalización por pedido de un tercero (HDT), hospitalización de oficio (HO) ... hasta el concepto reciente de obligación de tratamiento. Nuestra tesis comienza revisando estos aspectos históricos para ubicar el contexto de los pasajes del acto, que luego será analizado a la luz de la enseñanza de Lacan. Vislumbramos la voz como un intento de sustitución a la forclución del Nombre del Padre, la voz que viene a suplir y completar el silencio del Otro. Para hacer esto, desarrollamos varias ilustraciones clínicas.

La novela de Duras, lluvia de verano, nos permite entender la pulsión invocante como el eco de la voz del Otro y su resonancia corporal. Con Seth, la voz del padre y el diablo se confunden, un pacto de alianza entre los padres terribles que prohíben y las figuras femeninas. Con la Sra. X, nos estamos acercando a los aspectos de la fórmula de Lacan: en la psicosis, la voz sonoriza la mirada. Podemos enseguida tomar en consideración lo que le sucede a Chris que no soporta la voz. La cuestión del reverso del autocastigo la abordamos con la paciente Medea. Nos apoyamos en Gabriel García Márquez con crónica de un intento de muerte anunciado. Finalmente, intentamos de comprender el desencadenamiento de la psicosis en Telfusa, a quien las voces, según ella, la acompañan constantemente, incluso cuando habla. El tratamiento se presenta asi: no a Juana la loca, y si a la libertad. Esta tesis trata de poner en evidencia el valor propio de la palabra introducida por el psicoanálisis, esclareciendo la clínica del acto en el campo de las psicosis.

Considerable resources worldwide are invested in the research and development of future transportation technology. The foreseen direction and therefore research of future personalised transportation is focused on Battery Electric Vehicles (BEV) or hybrid combinations that use hydrogen fuel cells. These new transport energy systems are consider most to replace the current vehicles powered by the internal combustion engine (ICE). The research work presented in this thesis mainly focuses on the development of a software control system for future BEV prototype vehicles - a generic intelligent control system (GICS). The system design adopts a modular design concept and intelligent control. The whole system consists of four modules being communication, power supply, motor driver and transmission module. Each module uses a microcontroller as the brain and builds an embedded control system within the module. The control and communication between the modules is based on a group of specific parameters and the status of a state machine. In order to effectively implement intelligent control and simplify the system structure and programming, a generic intelligent fuzzy logic model that can be configured to a specific application with a near real-time buffered communication methodology is developed. The tests made on the fuzzy control model and the near real-time buffered communication gave a very positive outcome. The implementation of the fuzzy control and the communication methodology in each of the modules results in a communication between the modules with a steady speed, better reliability and system stability. These modules link together through the communication channels and form a multi-agent collaborative system (MACS). As the controllers are designed based on the parametric concept, the system is able to be implemented to future new modules and therefore allow prototype vehicle control systems to be developed more efficiently. The MACS is based on the core components of the control system - fuzzy logic controller (FLC), Serial Communication and Analogue input control software modules. Further work is carried out as an attempt to integrate the control software with a hardware design for a generic electric propulsion drive (GEPD). This thesis therefore outlines the design and considerations in software and hardware integration in addition to the GICS. The output from this thesis being the construction of soft programming modules for embedded microcontroller based control system has been accepted and presented at two international conferences; one in Wellington, New Zealand[1] the second in Acireale, Italy[2].

This thesis is part of a major research project to analyse vibro-acoustic characteristics from variable speed inverter driven induction motors (VSIDIM). The overall projects??? aimed at providing a better understanding of the mechanisms of sound generation from electromagnetic origins and developing a numerical model to predict the sound power emitted from a VSIDIM. The scope of this thesis is to assess experimentally the effect of various controller strategies on the radiated sound power and to develop a finite element method for calculating the electromagnetic force distribution over the stator. Various sources of noise in induction motors and their behaviour with speed and load have been reviewed. Models of the electromagnetic field and vibro-acoustic character have been discussed. An outline of various techniques of reducing noise in induction motors through design of inverters and modifications to the motor structure has been given. Experiments were conducted to assess the effect of controller strategies on the radiated sound power. Three different supplies were tested: a dynamotor which produces an almost sinusoidal supply with very low harmonic content, an inverter with a low switching frequency (less than 1kHz) and an inverter with a high switching frequency (8kHz) and various levels of random modulation. Results indicate that the sound power level of the MSC drive is a lot higher than that of the VSC 2000 drive and the dynamotor drive. The sound power level of the VSC 2000 drive and the dynamotor drive increases almost linearly with motor speed, that for the MSC drive is almost independent of speed. The sound power level of the MSC drive is almost 28dB higher than that of the dynamotor drive at 450rpm and the difference is reduced to 14dB at 1500rpm where the aerodynamic noise becomes more dominant. It has been found that at the rated speed (1500rpm), the sound power level varies by less than 3dB from no load to full load for all three sources. Although increasing the switching frequency increases the cost of the inverters and switching losses, results from the MSC and VSC 2000 drives clearly show that it reduces the radiated sound power by shifting the harmonics into higher and inaudible frequency range. The tonal nature around the switching frequency has been reduced by increasing the levels of random modulation to spread the energy over a wider range of frequencies, although the sound power level has not varied by more than 0.2dB. A finite element model has been developed to calculate the electromagnetic force distribution. The quasi-static solution method has been implemented by stepping the rotor through the time domain using a fine regular mesh in the air gap. The stator currents were experimentally obtained while the rotor currents were obtained using a 4 parameter state space model of the motor. Results of the simulation indicate the influence of stator and rotor slots, saturation and time harmonics in the current. The calculated electromagnetic force distribution has been used in a FEM/BEM acoustic model and SEA acoustic model to predict the radiated sound power which agrees reasonably well with the measured sound, thus validating indirectly the electromagnetic force simulations.

This thesis examines converter topologies suitable for Module Integrated Converters (MICs) in grid interactive photovoltaic (PV) systems, and makes a contribution to the development of the MIC topologies based on the two-inductor boost converter, which has received less research interest than other well known converters. The thesis provides a detailed analysis of the resonant two-inductor boost converter in the MIC implementations with intermediate constant DC links. Under variable frequency control, this converter is able to operate with a variable DC gain while maintaining the resonant condition. A similar study is also provided for the resonant two-inductor boost converter with the voltage clamp, which aims to increase the output voltage range while reducing the switch voltage stress. An operating point with minimized power loss can be also established under the fixed load condition. Both the hard-switched and the soft-switched current fed two-inductor boost converters are developed for the MIC implementations with unfolding stages. Nondissipative snubbers and a resonant transition gate drive circuit are respectively employed in the two converters to minimize the power loss. The simulation study of a frequency-changer-based two-inductor boost converter is also provided. This converter features a small non-polarised capacitor in a second phase output to provide the power balance in single phase inverter applications. Four magnetic integration solutions for the two-inductor boost converter have also been presented and they are promising in reducing the converter size and power loss.

<p>The aim of this thesis is to describe and understand the introduction of entrepreneurship and enterprise projects in primary and secondary schools in the North of Sweden and to identify and analyse the driving forces and actors behind this process. In particular the influence and significance of education policy at supranational, national and subnational level for the introduction of entrepreneurship and enterprise in education are analysed. The main questions of the study have been:</p><p>• How and why have entrepreneurship and enterprise education come to the schools in the northern region of Sweden, in particular within the framework of the PRIO1 project?</p><p>• How were important stakeholders involved at the subnational level and how did they reason and act in relation to the introduction of entrepreneurship and enterprise in the schools?</p><p>• How are the concepts of entrepreneurship and enterprise education presented in policy documents at different policy levels?</p><p>The study wants to report on changes in education policy during recent years. Especially the emergence of international policy convergence and new forms of governance are among the factors that are considered. Drawing on a conceptual framework of structure and agency, the analyses in the empirical studies are informed by a combination of theoretical fields. Important contributions are rendered from the education policy literature. The first method consists of a policy study of documents produced by organisations at different levels (supranational, national and subnational). The purpose of this analysis is to capture the ideas and arguments that have been used but also to understand the context and driving forces for the introduction of entrepreneurship and enterprise in education. Starting from the supranational level, the analysis focuses mainly on two organisations, OECD and EU. These organisations were chosen because they are widely regarded as leading organisations in setting the supranational policy agenda for education. The document study consists of a selection of OECD documents that have been released during the period 1970 - 2006, as well as a selection of EU documents. The EU documents cover the last 15 years. Attention is paid to several documents at the national and subnational level as well. The second method is an interview study. The interview study aims to focus on some of the key stakeholders (agents/actors) that have been participating in the formation (initiation, financing and realisation) of a county wide project “PRIO1”, Priority Enterprise in Västerbotten, in the North of Sweden. In order to understand why and how these actors at the subnational level have become involved in the process, there exists a need to hear their arguments. The document study shows that there is interplay between the different levels, but intertextual aspects have also become visible. The policy drive and policy scope show the concatenation but also the complexity of the policy development. Education is increasingly related to economic policies, in particular through labour market policies. Although the concepts of Entrepreneurship and Enterprise have developed within the economic sector, they are penetrating the education and training systems of many countries. From the results presented in this study, it seems that lifelong learning has become the guiding principle for the amalgamation of education and the world of work, while learning is no longer equated with just schooling. The opening of the school towards the surrounding world is a characteristic development in all this, but it is also a process that certainly is stipulated by agencies and actors at different levels, as is shown in this study. The interviews with some stakeholders at the subnational level show that the promotion of entrepreneurship and enterprise in education is related to arguments for economic and societal development. The interviews also reveal some of the “bottom-up” aspects of the policy process. One of the important results of this study is that the education policy studies have to include the level beyond the national borders. The interplay between the different policy-levels (supranational, national and subnational) needs more attention in order to understand the transformation of the education system.</p>

Most engineering systems are highly nonlinear in nature and thus one could not develop efficient mathematical models for these systems. Artificial neural networks, which are used in estimation, filtering, identification and control in technical literature, are considered as universal modeling and functional approximation tools. Unfortunately, developing a well trained monolithic type neural network (with many free parameters/weights) is known to be a daunting task since the process of loading a specific pattern (functional relationship) onto a generic neural network is proven to be a NP-complete problem. It implies that if training is conducted on a deterministic computer, the time required for training process grows exponentially with increasing size of the free parameter space (and the training data in correlation). As an alternative modeling technique for nonlinear dynamic systems / this thesis proposed a general methodology for structured neural network topologies and their corresponding applications are realized. The main idea behind this (rather classic) divide-and-conquer approach is to employ a priori information on the process to divide the problem into its fundamental components. Hence, a number of smaller neural networks could be designed to tackle with these elementary mapping problems. Then, all these networks are combined to yield a tailored structured neural network for the purpose of modeling the dynamic system under study accurately. Finally, implementations of the devised networks are taken into consideration and the efficiency of the proposed methodology is tested on four different types of mechanical systems.
