  text: Voting via the Internet has become a feasible option for political as well
    as non-political ballots. However, there are many obstacles which have to be overcome,
    especially legal restrictions have to be transformed into technical and security
    solutions. The article starts with a brief presentation of advantages and disadvantages
    of Internet ballots and presents application fields and pilot schemes. Then, technological
    security aspects are derived due to democratic basic principles. Especially the
    applied voting procedures are critical in security terms. Hence, the most relevant
    cryptographic protocols are presented and their drawbacks and shortcomings are
    identified. However, this article does not propose a new voting protocol. Beyond
    fixing cryptographic procedures for ballots, more elements are to be specified,
    e.g. responsibilities and rights of involved authorities or security precautions
    regarding hardware and software. For this reason, a structural security framework
    for electronic voting systems is presented which can be used for their composition
    and analysis.

  text: "The adiabatic driving of the resonant electron dynamics in a one-dimensional
    resonant photonic band gap is\r\nproposed as an optical mechanism for nonlinear
    ultrafast switching. Pulsed excitation inside the photonic gap\r\nresults in an
    ultrafast suppression and recovery of the gap. This behavior results from the
    adiabatic carrier\r\ndynamics due to rapid radiative damping inside the band gap."

  text: "In dieser Arbeit wird eine Theorie vorgestellt, welche die quantenmechanische
    Vielteilchenphysik\r\nder Licht-Materie Wechselwirkung in Halbleiternanostrukturen
    beschreibt. Diese mikroskopische Beschreibung\r\nwird durch Kombination eines
    allgemeinen Dichtematrixansatzes mit speziellen Methoden\r\nzur Auswertung der
    Maxwellgleichungen wie der zeitaufgelösten Finite-Differenzen-Methode\r\n(FDTD)
    erreicht. Die Theorie wird auf verschiedene physikalische Situationen angewendet,
    wie z.B.\r\nLichtausbreitung in Volumenhalbleitern, Interband- und Intersubbandübergänge
    in Quantenfilmstrukturen\r\nund optische Anregung von Quantenpunkten. Der Fokus
    liegt dabei auf der Beschreibung der\r\nlinearen und nichtlinearen Antwort des
    Vielteilchensystems und seiner Ankopplung an das elektromagnetische\r\nFeld. In
    diesem Zusammenhang wird sowohl die Erzeugung als auch der Zerfall von optischen\r\nAnregungen
    untersucht, indem verschiedene Kopplungsmechanismen wie Elektron-Phonon-,\r\nElektron-Photon-
    und Elektron-Elektron-Wechselwirkung berücksichtigt werden.\r\nIm Bereich der
    linearen Optik, also für Anregung mit geringer Intensität, ermöglicht die Theorie\r\ndie
    Berechnung von Absorptionsspektren. Verschiedene Effekte in linearer Optik werden
    in dieser\r\nArbeit untersucht und beschrieben: Linienaufspaltung durch Polaritonen
    im Volumenmaterial, Zunahme\r\nder Linienbreite bei Intersubbandübergängen verursacht
    durch Elektron-Elektron- und Elektron-\r\nPhonon-Streuung in einzelnen Quantenfilmen,
    Bildung einer optischen Bandlücke durch starke radiative\r\nKopplung in Vielfilmstrukturen
    in Bragg-Geometrie, Phononenseitenbänder verursacht durch\r\nquantenkinetische
    Effekte in einzelnen Quantenpunkten und schliesslich Superradianz und Interferenzeffekte\r\nin
    Quantenpunktgittern.\r\nBei nichtlinearer Anregung treten Dichte-Rabiflops als
    fundamentale Prozesse in allen betrachteten\r\nSystemen auf und können als kohärente
    Be- und Entvölkerung von quantenmechanischen Zuständen\r\nbeobachtet werden. Der
    Einfluss von starker Lichtkopplung und verschiedenen Wechselwirkungen\r\nauf dynamische
    Größen wie die Besetzung wird untersucht. Bei nichtlinearer Propagation, bei\r\nder
    sich ein starker Lichtpuls über längere Strecken in einem System bewegt, wird
    selbstinduzierte\r\nVerstärkung der Transmission näher betrachtet. Des weiteren
    werden von der Coulombwechselwirkung\r\nverursachte nichtlineare Effekte wie exzitoninduziertes
    Dephasieren in Volumenmaterial und\r\nverschränkte Zustände in Quantenpunkten
    untersucht, die einen Zusammenbruch der Hartree-Fock-\r\nNäherung darstellen.\r\nZusammenfassend
    werden in dieser Arbeit verschiedene lineare und nichtlineare optische Effekte\r\nin
    Halbleiternanostrukturen verschiedener Dimensionalität mit Hilfe einer allgemeinen
    Theorie, die\r\neinen Dichtematrixansatz mit den Maxwellschen Gleichungen kombiniert,
    untersucht."

  text: Spam als unerwünschte Massen-E-Mail hat die Grenze von der Belästigung zur
    ökonomischen Relevanz längst überschritten. Ihr relativer Anteil am gesamten,
    weltweiten E-Mail-Aufkommen stieg in den vergangenen Jahren auf mehr als 50% im
    Jahr 2003. Es entstehen jährlich volkswirtschaftliche Schäden in Milliardenhöhe.
    Zur Bekämpfung des Spam-Problems werden neben gesetzlichen Regelungen vor allem
    technische Lösungen eingesetzt, bei denen das Blockieren und Filtern von E-Mails
    in praktisch eingesetzten Anti-Spam-Systemen dominieren. Dieser Artikel führt
    in die Spam-Problematik ein und beschreibt, bewertet und klassifiziert die derzeit
    bedeutendsten Verfahren zur Bekämpfung von Spam.

  text: Spam as unsolicited e-mail to a large number of recipients is known to ecome
    an increasingly disturbing and costly issue of electronic business and internet
    traffic. Mainly technical-oriented approaches are applied with a focus on blocking,
    filtering, and authentication mechanisms based on the domain name system. They
    come along with different drawbacks and have all low effectiveness in common.
    The article sketches these approaches, shows its limitations, and proposes an
    account-based approach where the number of e-mails per day and account is restricted.

    and studies like the ?Voting Technology Project? of CALTECH and MIT or SERVE of
    the US Department of Defense set up to gain experience evidence many of the notional
    weaknesses of current Internet voting systems.

  text: Satellite positioning systems, such as GPS or the future European system Galileo,
    employ direct-sequence spread-spectrum signals. The positioning accuracy is strongly
    affected by the quality of the pseudo range measurements. These measurements necessitate
    code and carrier synchronization of the received signal with the internally generated
    reference signals. In this type of systems one major error source is the multipath
    phenomenon, which results in a sum of delayed and weighted copies of the original
    signal to be present at the receiver input. This can result in a systematic error
    of the code tracking loop resulting in range errors in the order of several tens
    of meters. In this paper we propose an extension of the standard code tracking
    loop capable of estimating the parameters of the line-of-sight (LOS) signal and
    separating the LOS from the reflected signal portions. It is based on an analysis
    of the cross correlation of the received signal with a locally generated code
    sequence in the vicinity of the tracking point of a Delay-Locked Loop (DLL). For
    this reason, we call this method Cross Correlation Function (CCF) Analysis. The
    proposed method achieves considerably more accurate estimates than a DLL. Its
    performance is comparable to the Multipath Estimating Delay-Locked Loop (MEDLL)
    which is considered to be the best method for reducing multipath induced errors,
    so far. However, the computational complexity of the CCF Analysis is by a factor
    of three smaller compared to the MEDLL. Extensive simulations have been conducted
    for the proposed method and the MEDLL in order to assess the robustness of the
    two approaches under various signal constellations.

  text: 'A major drawback of distributed versus terminal-based speech recognition
    is the fact that transmission errors can lead to degraded recognition performance.
    In this paper we employ soft features to mitigate the effect of bit errors on
    wireless transmission links: At the receiver a posteriori probabilities of the
    transmitted feature vectors are computed by combining bit reliability information
    provided by the channel decoder and a priori knowledge about residual redundancy
    in the feature vectors. While the first-order moment of the a posteriori probability
    function is the MMSE estimate, the second-order moment is a measure of the uncertainty
    in the reconstructed features. We conducted realistic simulations of GSM transmission
    and achieved significant improvements in word accuracy compared to the error mitigation
    strategy described in the ETSI standard.'
