Seduction and femininity in transference

Buscam-se as relações entre a sedução e a transferência em psicanálise. Segue-se o desenvolvimento laplanchiano de que a transferência é provocada pelo analista, sendo essa provocação entendida ao modo de uma reativação da situação originária de sedução e passividade. Argumenta-se, então, sobre a facilitação, em psicanálise, do estabelecimento de circulação de fantasias da sexualidade "feminina", entendida também como originária. Discute-se, por fim, a presença da alteridade na relação transferencial em face da idéia, de Jacques André, do outro como o feminino. ________________________________________________________________________________________ ABSTRACTThis essay develops considerations on the relations between seduction and transference in psychoanalysis. Following Laplanche's suggestion, transference, in so far as it reactivates the originary situation of seduction and passivity, it is understood to be provoked by the analyst. Psychoanalysis is considered to facilitate the circulation of fantasies of "feminine" sexuality — also regarded as originary. The presence of alterity in transference is discussed from the point of view of J. André's comprehension of the other as feminine

A new tracking approach for multipath mitigation based on antenna array

In Global Navigation Satellites Systems (GNSS), multipaths (MP) are still one of the major error sources. The additional signal replica due to reflection will introduce a bias in conventional Delay Lock Loops (DLL) which will finally cause a strong positioning error. Several techniques, based on Maximum Likelihood estimation (ML), have been developed for multipaths mitigation/estimation such as the Narrow correlator spacing [1] or the Multipath Estimating Delay-Lock-Loop (MEDLL) [2] algorithm. These techniques try to discriminate the MP from the Line Of Sight Signal (LOSS) on the time and frequency domains and thus, short delay multipaths (<0.1Chips) can not be completely mitigated. Antenna array perform a spatial sampling of the wave front what makes possible the discrimination of the sources on the space domain (azimuth and elevation). As the time-delay domain and space domain can be assumed independent, we can expect to mitigate/estimate very short delay MP by using an antenna array. However, we don't want to increase too much the size, the complexity and the cost of the receivers and thus, we focus our study on small arrays with a small number of antennas: typically a square 2x2 array. Consequently, conventional beamforming (space Fast Fourier Transform) is not directive enough to assure the mitigation of the multipaths, and then this first class of solutions was rejected. In order to improve the resolution, adaptive beamformers have also been tested. However, the LOSS and the MP signal are strongly correlated and thus, classical adaptive algorithms [3] are not able to discriminate the sources. These preliminary studies have shown that the mitigation/estimation of multipaths based on the space domain will exhibit limited performances in presence of close sources. Then, in order to propose robust algorithms, we decided to investigate a space-time-frequency estimation of the sources. Space Alternating Generalized Expectation maximisation (SAGE) algorithm [4], which is a low-complexity generalization of the Expectation Maximisation (EM) algorithm, has been considered. The basic concept of the SAGE algorithm is the hidden data space [4]. Instead of estimating the parameters of all impinging waves in parallel in one iteration step as done by the EM algorithm, the SAGE algorithm estimates the parameters of each signal sequentially. Moreover, SAGE algorithm breaks down the multi-dimensional optimization problem into several smaller problems. In [5], it can be seen that SAGE algorithm is efficient for any multipaths configurations (small relative delays, close DOAs) and space-time-frequency approach is clearly outperforming classical time-frequency approaches. Notwithstanding, SAGE algorithm is a post processing algorithm. Thus, it's necessary to memorise in the receiver the incoming signal in order to apply SAGE estimation. For example, if we want to process 10ms of signal with a 10MHz sampling rate, we need to store a matrix of m*105 with m the number of antennas. In such condition, we can understand than SAGE algorithm is hardly implemented in real time. The challenge is then to find a new type of algorithms that reach the efficiency of the SAGE algorithms, but with a reduced complexity in order to enable real time processing. Furthermore, the implementation should be compatible with conventional GNSS tracking loops (DLL and PLL). To cope with these two constraints, we propose to apply the SAGE algorithm on the post-correlated signal. Indeed, the correlation step can be seen as a compression step and thus, the size of the studied signal is strongly reduced. In such a way, SAGE algorithm is able to provide estimates of the relative delay and Doppler of the received signals with respect to the local replicas. Thus, a post correlation implementation of SAGE can be seen as a discriminator for both the DLL and the PLL

A new multipath mitigation method for GNSS receivers based on antenna array

the potential of small antenna array for multipath mitigation in GNSS systems is considered in this paper. To discriminate the different incoming signals (Line of sight and multipaths), a new implementation of the well known SAGE algorithm is proposed. This allows a significant complexity reduction and it is fully compatible with conventional GNSS receivers. Theoretical study thanks to the Cramer Rao Bound derivation and tracking simulation results (in static and dynamic scenarios) show that the proposed method is a very promising approach for the multipath mitigation problem in GNSS receivers

Psychoanalysis is the name of a labour

Este texto é parte integrante de uma investigação em busca do sentido da psicanálise, ou dos sentidos que ela possa apresentar. Busca-se justificar e apreender o sentido originário e fundamental da psicanálise. Enfoca-se a compreensão freudiana que a entende inicialmente como uma intencionalidade puramente terapêutica, mostrando-se que, antes de constituir-se como conhecimento, a psicanálise é assumida como ato, isto é, trabalho de tratamento da neurose. “Psicanálise” foi o nome dado por Freud a esse trabalho. Em conclusão, discute-se o sentido desse trabalho, cujo nome permite circunscrever, apontando-se o seu método e o seu objeto.This text is part of an investigation on the meaning of psychoanalysis, or the meanings it may(can) present. It aims to justify and apprehend the originary and fundamental meaning of psychoanalysis. Freudian comprehended psychoanalysis as having a purely therapeutic aim. Before consisting of knowledge, psychoanalysis was understood as a therapeutic act, that is, as labour of treatment of the neurosis. This labour circumscribed by the name – “psychoanalysis” – is discussed, and its method and object are pointed out

Contemporary “Dora” : and the therapeutic crisis of psychoanalysis

O artigo revisita o Caso Dora, de Freud, com o objetivo de pontuar sua contemporaneidade. Sustenta-se o argumento de que os impasses da psicanálise, revelados pela conclusão precipitada da análise dessa jovem da Viena de 1900, são tão questionadores e críticos à função terapêutica da psicanálise como o são os chamados casos difíceis da contemporaneidade. Discutem-se as mudanças ocorridas do método de tratamento anunciadas no caso Dora e sua falência diante desse caso de histeria. Mostra-se o privilégio concedido por Freud ao conhecimento do psiquismo, como meio de solução das dificuldades da psicanálise. Concluindo, sugere-se que foi o caráter pulsional da sexualidade o motivo dos empecilhos da análise de Dora, tendo os aspectos da interpretação da sexualidade e das relações de objeto tido menor peso para seu desfecho. Estende-se essa compreensão para as demandas contemporâneas de psicanálise.This paper revisits Freud’s Case of Dora to point out its contemporariness. It sustains that psychoanalysis’ deadlocks, as revealed by the sudden conclusion of the analysis of this young Viennese in 1900, are as questioning and critical to the therapeutic function of psychoanalysis as the so called difficult contemporary cases. The changes in the treatment method announced in the Case of Dora, as well as its failure in this case of hysteria, are discussed. The privilege given by Freud to knowledge of the psychic as the means of solving psychoanalysis’ deadlocks is shown. The paper concludes that the major obstacle in Dora’s analysis was the instinctual character of sexuality, rather than the interpretation of sexuality and of object-relations. This comprehension is extended to the contemporary demands for psychoanalysis
