3DGS.zip: A survey on 3D Gaussian Splatting Compression Methods
3D Gaussian Splatting (3DGS) is a powerful technique for real-time radiance field rendering but is limited by its high storage and memory requirements. This survey provides the first comprehensive analysis of existing compression and compaction...
Designing Citizen Science tools towards increased awareness and participatory policy making for air quality: The Case of COMPAIR
The EU-funded project COMPAIR designed advanced monitoring and simulation tools that aggregate data from multiple sources to provide a well-rounded view of air pollution and related challenges e.g. traffic, waste management, energy use. Built-in...
3D photonic integrated interposer enabling connectivity between multicore fibers and photonic integrated circuits
A novel 3D photonic integrated interposer is developed for coupling the different layers of Multi-core-fiber (MCF) cores with arrays of conventional 2D electro-absorption modulated lasers (EMLs) and photodetectors (PDs). The 3D photonic...
Next Generation XR Systems-Large Language Models Meet Augmented and Virtual Reality
Extended Reality (XR) is evolving rapidly, offering new paradigms for humancomputer interaction. This position paper argues that integrating Large Language Models (LLMs) with XR systems represents a fundamental shift toward more intelligent,...
Experimental Demonstration of a Correlation-Avoidance CMA for Blind Space-Division Multiplexed MIMO Equalization
We demonstrate blind 6x6 adaptive equalization of 32 GBd DP-QPSK 3-mode transmission over a 54 km FMF based on the singularity-free convergence ability of the correlation-avoidance CMA (CA-CMA). The CA-CMA is used for robust pre-convergence in a...
Data Governance Framework for Telemetry Sharing
We propose a novel solution using the Eclipse Dataspace Components (EDC) Connector to enable regulated and policy-driven telemetry data sharing in telco ecosystems. We present its architecture, several compatible use-cases, and results validating...
Adaptive and Temporally Consistent Gaussian Surfels for Multi- view Dynamic Reconstruction
We propose AT-GS, a novel method for reconstructing high-quality dynamic surfaces from multi-view videos through per-frame incremental optimization. To avoid local minima across frames, we introduce a unified and adaptive gradient-aware...
7.75 Gbit/s LiFi Transmitter Using High-Power VCSEL Arrays
We report on a wide-beam LiFi transmitter using multiple VCSEL arrays with digital drivers. We transmit a 3.75 GBd PAM-3 signal at a gross data rate of 5.625 Gbit/s. Single-driver OOK operation yields 7.75 GBd.
3D-Printed Dual-Polarized Magneto-Electric Dipole Antenna with Wideband High Isolation for Full-Duplex Applications
This paper presents a dual-polarized magneto-electric dipole antenna with orthogonal Gamma and inverted-Gamma probes, fabricated via 3D metal printing. It offers a 3-4 GHz impedance bandwidth, with excellent cross-polarization isolation (>50...
Improving Geometric Consistency for 360-Degree Neural Radiance Fields in Indoor Scenarios
NeRFs struggle with low-textured areas, causing "floaters" that reduce realism, especially on featureless surfaces. We propose a method for computing dense depth priors for these areas, using a novel depth loss function and patch regularization...
