Dos décadas de una atormentada relación: Martin Heidegger y Edmund Husserl 1909-1929

La publicación reciente de documentos y la consulta directa en archivos posibilita un acercamiento renovado a la conflictiva relación entre Edmund Husserl y Martin Heidegger. El artículo lleva a cabo esto mediante una revisión del camino académico de Heidegger a la sombra de su protector Husserl. De ese modo se dejan ver las escisiones anímicas del joven Heidegger, su apropiación de la fenomenología husserliana y a la vez su distanciamiento del maestro. Con ello también se muestra que el rompimiento entre ambos pensadores no tiene su origen en los compromisos políticos de Heidegger en 1933, sino que era algo que latía desde el inicio de la relación.

IB-DFE receiver techniques for CP-assisted block transmission within DS-CDMA and MC-CDMA systems

MC-CDMA (MultiCarrier Code Division Multiple Access), currently regarded as a promissing multiple access scheme for broadband communications, is known to combine the advantages of an OFDM-based (Orthogonal Frequency Division Multiplexing), CP-assisted (Cyclic Prefix) block transmission with those of CDMA systems. Recently, it was recognised that DS-CDMA (Direct Sequence) implementations can also take advantage of the beneficts of the CP-assisted block transmission approach, therefore enabling an efficient use of FFT-based (Fast Fourier Transform), chip level FDE (Frequency- Domain Equalisation) techniques. In this paper we consider the use of IB-DFE (Iterative Block Decision Feedback Equalisation) FDE techniques within both CP-assisted MC-CDMA systems with frequency-domain spreading and DS-CDMA systems. Our simulation results show that an IB-DFE receiver with moderate complexity is suitable in both cases, with excellent performances that can be close to the single-code matched filter bound (especially for the CP-assisted DSCDMA alternative), even with full code usage.

Joint turbo equalization and cancelation of nonlinear distortion effects in MC-CDMA signals

In this paper, we consider low-PMEPR (Peak-to-Mean Envelope Power Ratio) MC-CDMA (Multicarrier Coded Division Multiple Access) schemes. We develop frequencydomain turbo equalizers combined with an iterative estimation and cancellation of nonlinear distortion effects. Our receivers have relatively low complexity, since they allow FFT-based (Fast Fourier Transform) implementations. The proposed turbo receivers allow significant performance improvements at low and moderate SNR (Signal-to-Noise Ratio), even when a low-PMEPR MC-CDMA transmission is intended.

Les Lionel Groulx : la pseudonymie comme stratégie littéraire et jeu institutionnel (1900-1966)

De 1900 à 1966, Lionel Groulx, prêtre, historien, écrivain, conférencier, professeur, a signé 176 textes d'une vingtaine de pseudonymes différents. Le premier chapitre du mémoire résume d'abord les positions théoriques qu'ont adoptées des chercheurs comme Genette, Laugaa et Jeandillou en ce qui concerne la pseudonymie. Le récit de l'aventure pseudonyme de Groulx commence au deuxième chapitre, alors que le jeune professeur du College de Valleyfield, surtout pour éviter les représailles de son évêque, recourra à la pseudonymie pour signer des textes patriotiques. En 1915, Groulx quitte Valleyfield pour Montréal. Dès 1917, il collabore à l'Action française, dont il devient le directeur en 1920. Sans contredit, l'étude de la pseudonymie de Groulx de 1917 a 1929 prouve qu'il est bel et bien "L'Homme à tout faire" de la revue, comme le démontre le troisième chapitre. Le quatrième et dernier chapitre analyse la période 1930 à 1966. [Résumé abrégé par UMI]

Turbo equalization with cancellation of nonlinear distortion effects for CP-Assisted and Zero-Padded MC-CDMA signals

We consider MC-CDMA schemes, with reduced envelope fluctuations. Both CP-assisted (cyclic prefix) and ZP (zero-padded) MC-CDMA schemes are addressed. We develop turbo FDE (frequency-domain equalization) schemes, combined with cancelation of nonlinear distortion effects. The proposed turbo receivers allow significant performance improvements at low and moderate SNR, even when the transmitted signals have reduced envelope fluctuations.

Desempenho da flotação por ar dissolvido na remoção de cianobactérias de diferentes morfologias

A presença de cianobactérias em reservatórios utilizados para produção de água para consumo humano representa um elevado risco para a saúde pública. Estes organismos contribuem para a redução da qualidade da água e têm a capacidade de produzir cianotoxinas que podem afectar a saúde humana e animal. Existem casos em todo o mundo de intoxicação letal de diversos animais por consumo de água de lagos contaminados com cianobactérias, e mesmo casos de morte de humanos, atribuídas à exposição de cianotoxinas. De modo a fazer face a este crescente problema é necessário desenvolver e implementar tecnologias de tratamento de água nas ETA que permitam fazer face a uma florescência de cianobactérias num reservatório de água destinado ao abastecimento humano. Neste trabalho avaliou-se a capacidade do processo C/F/DAF na remoção cianobactérias de diferentes morfologias, células e colónias de M. aeruginosa e filamentos de P. rubescens, em águas sintéticas hidrofóbicas e hidrofílicas, com concentração de DOC moderada e moderada/elevada. Assim como da sequência C/F/DAF→NF na remoção de células e de toxinas de cianobactérias. A remoção de NOM e o seu efeito na remoção de cianobactérias foram também avaliados. Concluiu-se que o processo C/F/DAF é eficiente na remoção de cianobactérias de diferentes morfologias, com remoções entre 78 e 100% de MC intra. No entanto, a morfologia que apresentou remoções mais elevadas foram os filamentos, enquanto as colónias apresentaram valores mais baixos. Globalmente, verificou-se que o aumento da concentração de NOM facilita a remoção de cianobactérias, sendo que as águas hidrofóbicas apresentaram-se mais fáceis de tratar por C/F/DAF. Por sua vez, o tratamento C/F/DAF→NF, é uma opção eficiente para fazer face a um eventual bloom de cianobactérias em ETA, uma vez que a remoção de cianobactérias (em MC intra e chl_a) foi de 100% e a remoção de microcistina extracelular de 95%, aproximadamente.

Multiuser Detection for the Uplink of Prefix-Assisted DS-CDMA Systems Employing Multiple Transmit and Receive Antennas

In this paper we consider the uplink transmission within a DS-CDMA system employing CP-assisted (Cylic Prefix) block transmission techniques combined with spatial multiplexing techniques that require multiple antennas at both the transmitter and the receiver. We present an efficient frequency-domain receiver structure with iterative MUD (MultiUser Detection). The performance of the proposed receiver can be close to the single user matched filter bound, even for fully loaded systems and/or severely time-dispersive channels.

Globale Finanz- und Wirtschaftskrise : Ursachen, Verantwortung, Konsequenzen. Dokumentation der öffentlichen Vorträge am 16. Juni 2006

Die Weltwirtschaftskrise des Jahres 1929 beendete ein „goldenes Zeitalter“. Sie veränderte nachhaltig die internationale Völkergemeinschaft, unter anderem in Bezug auf den Welthandel, die Finanzströme und die Arbeitslosigkeit. Die Auswirkungen unserer heutigen Krise scheinen vergleichbar, die Ausgangslage, Ursachen und Verantwortung sind jedoch grundverschieden.
Kein Lehrbuch und keine Vorlesung haben uns auf diese Krisenform vorbereitet. Auch liegen keine wirtschaftspolitischen Erfahrungen vor, die als Grundlage zur Bewältigung einer Krise in dieser Dimension dienen könnten. Aber wir können– obgleich die Krise andauert – schon heute beobachten, dass die Konsequenzen anders ausfallen und zu langfristigen, einschneidenden Veränderungen führen.
Mit unserer Fachveranstaltung bieten wir Erklärungsansätze und diskutieren über Verantwortung und Konsequenzen. Drei Beiträge führen aus unterschiedlichen Perspektiven in das Thema ein.
