La constellation paternelle : une étude pilote en période prénatale

À partir d'une recherche où nous avions mis en évidence que certaines représentations maternelles prénatales concernant le nourrisson avaient un impact décisif sur les interactions précoces (Cupa et al., 1992), nous nous sommes demandés, en parallèle, quel était le poids, sur ces mêmes interactions, des représentations paternelles pendant la grossesse, sachant qu'à cette période les remaniements psychiques du père sont profonds (Bouchard-Godard, 1976 ; Cupa et al., 1997). Si, dans l'entrecroisement des deux champs théoriques où nous situons notre travail, à savoir celui de la psychanalyse et celui de la psychologie développementale, nous trouvons une littérature importante sur le père, peu de recherches concernent la période de la grossesse. Nous exposerons, pour cela, dans une première partie, les résultats et contributions permettant d'apprécier la portée des travaux sur le père, lors de la grossesse, et de présenter les points d'appels théoriques de nos hypothèses. La présentation de notre travail qui suit est celle d'une recherche comparative longitudinale qui s'étend du 7e mois de la grossesse jusqu'au 9e mois après la naissance. Il nous est apparu en effet qu'afin d'explorer simultanément les deux univers représentationnels parentaux et d'en observer les effets sur les interactions triadiques, ce type de méthodologie était le plus pertinent. Les résultats proposés, en dernière partie, concernent uniquement l'analyse des représentations paternelles.The paternal constellation: a pilot study in prenatal period In a research where the authors had argued that some maternal prenatal representations concerning the infant had a decisive impact on precocious interactions (Cupa et al., 1992), they have asked in parallel, what was the weight on these very same interactions of paternal representations during pregnancy, knowing that in this specific period psychic reorganization of the father are profound (Bouchard-Godard, 1976; Cupa et al., 1997). If, in the intertwining of the two theoretical fields where the authors situate their work, being that of psychoanalysis and developmental psychology, there is a an important literature on the father, results and contribution allow to appreciate the impact of studies on the father during pregnancy and present theoretical points of reference of the authors' hypotheses. The presentation of the following study is that of a comparative longitudinal research carried out from the 7th month of pregnancy to 9 months after birth. It appeared indeed to the authors that in order to explore simultaneously the two representational universes and to observe the effects on the triadic interactions, this type of methodology was the most relevant. The results proposed in the last part, only concern the analysis of paternal representations.La constelación paternal: un estudio en perioda prenatal A partir de una investigación dónde ponen en evidencia que ciertas representaciones maternales prenatales relativo al niño lactante tienen un impacto decisivo sobre las interacciones precoces (Cupa et al., 1992), los autores se preguntan, en paralelo, cual es el peso, sobre estas mismas interaciones, de las representaciones paternales durante el embarazo, sabiendo que durante esta perioda las transformaciones síquicos del padre son profundas (Bouchard-Godard, 1976; Cupa et al., 1997). Si, en el entrecruzamiento de los dos campos teóricos dónde se ubica el trabajo, a saber el de la sicoanálisis y el de la sícologia developmental, se encontró una literature importante sobre el padre, muy pocas investigaciones relativo a la perioda del embarazo se consiguieron. Se expone, por eso, en una primera parte, los resultados y contribuciones permitiendo apreciar el alcance de los trabajos sobre el padre durante el embarazo y presentar los puntos teóricos de sus hipotesís. La presentación del trabajo resulta de una investigación comparativa longitudinal la cual se extiende del septimo mes de embarazo hasta el noveno mes. Les apareció que para explorar simultáneamente los dos universos representativos parentales y de observar les efectos sobres las interaciones triadicas, este tipo de metodologia era más pertinente. Los resultados propuestos, en la última parte, se refieren unicamente al análisis de las representaciones paternales

Attitude Determination from Single-Antenna Carrier-Phase Measurements

A model of carrier phase measurement (as carried out by a satellite navigation receiver) is formulated based on electromagnetic theory. The model shows that the phase of the open-circuit voltage induced in the receiver antenna with respect to a local oscillator (in the receiver) depends on the relative orientation of the receiving and transmitting antennas. The model shows that using a {\it single} receiving antenna, and making carrier phase measurements to seven satellites, the 3-axis attitude of a user platform (in addition to its position and time) can be computed relative to an initial point. This measurement model can also be used to create high-fidelity satellite signal simulators that take into account the effect of platform rotation as well as translation.Comment: 12 pages, and one figure.

The Level 0 Trigger Decision Unit for the LHCb experiment

The Level 0 Decision Unit (L0DU) is one of the main components of the first trigger level (named level 0) of the LHCb experiment. This 16 layers custom board receives data from the calorimeter, muon and pile-up sub-triggers and computes the level 0 decision, reducing the rate from 40MHz to 1MHz. The processing is implemented in FPGA using a 40MHz synchronous pipelined architecture. The L0DU algorithm is fully configured via the Experiment Control System without any firmware reprogramming. An overall L0DU latency of less than 450ns has been achieved. The board was installed in the experimental area in April 2007 and since then has played a major role in the commissioning of the experiment

A Hybrid Simulation Model to Predict the Steady-State Thermal Profile of Hermetic Reciprocating Compressors

Numerical simulation models are paramount to design compressors that follow reliability and efficiency requirements. This paper presents a simulation model to predict the steady-state thermal profile of hermetic reciprocating compressors. A finite element method is used to compute the temperature distribution of the solid components and the fluid in the suction and discharge lines, whereas a lumped-parameter formulation is used to evaluate the internal environment temperature and the gas temperature at the end of the compression cycle. The heat transfer between the gas and the solid components is predicted using imposed convective heat transfer coefficients; some of which are estimated using heat transfer correlations, and others calibrated using experimental data and a genetic optimization algorithm. The numerical results were validated by comparisons with experimental data for different operating conditions and rotation speeds, showing that the model can be used to predict the compressor thermal profile in the entire application envelope. The low computational cost of the model enables its application to carry out sensitivity analysis and to assess thermal management alternatives to improve the compressor reliability or thermodynamic performance
