Einschränkung Bahnverkehr Zürich wegen Fahrleitungsstörung
Der Bahnverkehr auf der Strecke Zürich Oerlikon - Zürich HB ist zwischen Zürich Oerlikon und Zürich Hardbrücke eingeschränkt.
Der Grund dafür ist eine Fahrleitungsstörung.
Die Einschränkung dauert bis zirka 08:00.
Betroffen sind die Linien S, S15, S16 und S21.
Es sind Verspätungen, Ausfälle und Umleitungen zu erwarten.

Como imputen de mšs delitos a Netanyahu Israel se va a quedar sin países enemigos a los que bombardear y va a tener que empezar a bombardear a sus amigos.

Interference in Spectrum-Sharing Integrated Terrestrial and Satellite Networks: Modeling, Approximation, and Robust Transmit Beamforming
This paper investigates robust transmit (TX) beamforming from the satellite to user terminals (UTs), based on statistical channel state information (CSI). The proposed design specifically targets the mitigation of satellite-to-terrestrial interference in spectrum-sharing integrated terrestrial and satellite networks. By leveraging the distribution information of terrestrial UTs, we first establish an interference model from the satellite to terrestrial systems without shared CSI. Based on this,…

Acaba de me ocorrer que, por conta da fumaça, eu desci as escadas com uma toalha molhada no rosto, que depois ficou apoiada no meu ombro. Então, enquanto esperava na rua os bombeiros fazerem o seu trabalho, eu o tempo inteiro sabia aonde estava a minha toalha, como bom #MochileiroDasGaláxias que sou rs.

Automatic Generation of Explicit Quadratic Programming Solvers
We consider a family of convex quadratic programs in which the coefficients of the linear objective term and the righthand side of the constraints are affine functions of a parameter. It is well known that the solution of such a parametrized quadratic program is a piecewise affine function of the parameter. The number of (polyhedral) regions in the solution map can grow exponentially in problem size, but when the number of regions is moderate, a so-called explicit solver is practical. Such a so…

Mich schaudert es bei der Vorstellung wieviel Verwaltungsaufwand in diesen Kleinklein-Bullshit geht. Vom "Im Computer anlegen" bis zum "BordBistro-Hanseln schulen". Macht mal lieber ordentliche Preise und pünktliche Züge. Dann kommt die Auslastung von allein.

Design of 3D Beamforming and Deployment Strategies for ISAC-based HAPS Systems
This paper explores high-altitude platform station (HAPS) systems enabled by integrated sensing and communication (ISAC), in which a HAPS simultaneously transmits communication signals and synthetic aperture radar (SAR) imaging signals to support multi-user communication while performing ground target sensing. Taking into account the operational characteristics of SAR imaging, we consider two HAPS deployment strategies: (i) a quasi-stationary HAPS that remains fixed at an optimized location dur…

Hadamard Encoded Row Column Ultrasonic Expansive Scanning (HERCULES) with Bias-Switchable Row-Column Arrays
Top-Orthogonal-to-Bottom-Electrode (TOBE) arrays, also known as bias-switchable row-column arrays (RCAs), allow for imaging techniques otherwise impossible for non-bias-switachable RCAs. Hadamard Encoded Row Column Ultrasonic Expansive Scanning (HERCULES) is a novel imaging technique that allows for expansive 3D scanning by transmitting plane or cylindrical wavefronts and receiving using Hadamard-Encoded-Read-Out (HERO) to perform beamforming on what is effectively a full 2D synthetic receive a…

Near-Field Sensing Enabled Predictive Beamforming: Fundamentals, Framework, and Opportunities
The article proposes a novel near-field predictive beamforming framework for high-mobility wireless networks. Specifically, due to the spherical waves and non-uniform Doppler frequencies brought by the near-field region, the new ability of full-dimensional location and velocity sensing is characterized. Building on this foundation, the near-field predictive beamforming framework is proposed to proactively design beamformers for mobility users following arbitrary trajectories. Compared to the co…

Movable-Antenna Array Enhanced Downlink NOMA
Movable antenna (MA) has gained increasing attention in the field of wireless communications due to its exceptional capability to proactively reconfigure wireless channels via localized antenna movements. In this paper, we investigate the resource allocation design for an MA array-enabled base station serving multiple single-antenna users in a downlink non-orthogonal multiple access (NOMA) system. We aim to maximize the sum rate of all users by jointly optimizing the transmit beamforming and th…
