Multidimensional Assessment of Public Space Quality: A Comprehensive Framework Across Urban Space Typologies
This study presents a comprehensive framework for evaluating the quality of public spaces across various urban typologies. Through a systematic review of 159 research studies, we identify universal quality factors that transcend spatial types as well as specialized factors unique to specific public environments. Our findings establish accessibility (73.6%), safety/security (58.4%), and comfort (52.8%) as foundational requirements across all public space types, while revealing distinct quality p…

Co-Win: Joint Object Detection and Instance Segmentation in LiDAR Point Clouds via Collaborative Window Processing
Accurate perception and scene understanding in complex urban environments is a critical challenge for ensuring safe and efficient autonomous navigation. In this paper, we present Co-Win, a novel bird's eye view (BEV) perception framework that integrates point cloud encoding with efficient parallel window-based feature extraction to address the multi-modality inherent in environmental understanding. Our method employs a hierarchical architecture comprising a specialized encoder, a window-based b…

On the Limitations of Ray-Tracing for Learning-Based RF Tasks in Urban Environments
We study the realism of Sionna v1.0.2 ray-tracing for outdoor cellular links in central Rome. We use a real measurement set of 1,664 user-equipments (UEs) and six nominal base-station (BS) sites. Using these fixed positions we systematically vary the main simulation parameters, including path depth, diffuse/specular/refraction flags, carrier frequency, as well as antenna's properties like its altitude, radiation pattern, and orientation. Simulator fidelity is scored for each base station via Sp…

Marina Hyde is a brilliant columnist:
Imagine owning the world’s premier shitposting platform – in fact, having spent $44bn on it, specifically so that your magic mirror would tell you each day that you were the fairest shitposter of all – and then shuffling sheepishly on to your own pixels to mumble something about having gone “too far” with your hurty words.

Complexity Analysis of a Bicriteria Directed Multimodal Transportation Network Design Problem
In this paper, we address a bicriteria network design problem that arises from practical applications in urban and rural public transportation planning. We establish the problem's complexity and demonstrate inapproximability results, highlighting the inherent difficulties in finding optimal solutions. Additionally, we identify special cases where approximability can be achieved, providing valuable insights for practitioners. Our proofs leverage complexity results related to directed network des…

”The staff was incredibly helpful and welcoming, just like I remembered. A special mention goes to X, the talented barman, who once again delivered drinks that were not only delicious but prepared with real dedication and professionalism. His attention to detail and friendly approach added so much to the overall experience.
Whether it's your first visit or your fifth, Y is a must-stop in Graz for anyone who appreciates quality drinks, great service, and a perfect city cent…
