Intraoperative measurements in stapedotomy using 3D stereo imaging for optimal prosthesis length selection
This study introduces a novel approach for precise, radiation-free intraoperative measurements using 3D stereoscopic imaging integrated into a digital surgical microscope for stapedotomy. By optimizing the calibration of stereoscopic zoom-focus...
Kernel-Based Signal Processing for Simultaneous Transmit-Receive Systems
We address digital self-interference cancellation (SIC) in simultaneous transmit-receive systems using data-driven approaches. We propose kernel-based learning methods -- adaptive projected subgradient method (APSM) and support vector regression...
Record length of 2000km weakly-coupled 7-core MCF produced from a single large-scale MCF preform
We present the design and fabrication of more than 2000 km of a 7-core multi-core fiber (MCF) drawn from a single large-scale MCF preform. The fiber was fabricated without any online fiber breaks and exhibits axially excellent geometrical...
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...
Artificial Neural Network With Photonic Reservoir for Multiclass Modulation Format Identification
We successfully achieved MFI using a neuromorphic PIC with a photonic reservoir and digital readout, both in a laboratory environment and with commercial network equipment.
Resolution and Speed Trade-offs in FMCW LiDAR with MEMS Mirror Scanning and Advanced Signal Processing
We address system trade-offs, e.g. between resolution and speed of a coherent scanning LiDAR. We analyze the performance of our real-time FMCW LiDAR prototype with a high-quantumefficiency coherent receiver, two-dimensional...
Joint power control, beamforming, and sleep-mode selection for energy-efficient cell-free networks using surrogate machine learning models
In cell-free networks, system throughput is enhanced by allowing more than one access point (AP) to serve each user, which may lead to high energy consumption. To circumvent this, this paper presents a surrogate optimization technique using...
Global or local modeling for XGBoost in geospatial studies upon simulated data and German COVID-19 infection forecasting
This research compares the local- and global modeling ways of XGBoost in the geospatial studies. Two experiments based on simulation data and German COVID-19 infection data were conducted to compare the two modeling ways from multiple aspects....
SPNeRF: Open Vocabulary 3D Neural Scene Segmentation with Superpoints
We introduce SPNerf, a NeRF based zero-shot 3D segmentation approach that leverages geometric priors. We integrate geometric primitives derived from 3D scene into NeRF training to produce primitive-wise CLIP features, avoiding the ambiguity of...
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...
