Uneven landscapes and the city size distribution [PDF]

open access: yes, 2010
This paper proposes a new explanation for Zipf’s law often observed in the top tail of city size distribution. We show that Zipf’s law can emerge if city size can be expressed as a product of multiple random factors. Each of the factors need not generate

Field-of-View IoU for Object Detection in 360{\deg} Images

open access: yes, 2022
360{\deg} cameras have gained popularity over the last few years. In this paper, we propose two fundamental techniques -- Field-of-View IoU (FoV-IoU) and 360Augmentation for object detection in 360{\deg} images.

Impacts of urbanization on the distribution of heavy metals in soils along the Huangpu River, the drinking water source for Shanghai [PDF]

open access: yes, 2015
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections with urbanization, and their ...

應用蜂群演算法於結構最佳化設計之研究 [PDF]

open access: yes
[[abstract]]本論文應用蜂群演算法於結構最佳化設計中。蜂群演算法是一種模仿自然界蜜蜂覓食行為進行問題求解之方法,該法為具有群體智慧的仿生演算法,其特點為收斂速度快、參數設定少及搜尋範圍廣。蜂群演算法利用其獨特的雇用蜂以及非雇用蜂的方式進行大範圍的搜尋以尋求全域最佳解。過程中藉由食物源採用機率判斷是否採用當前最佳解,如此反覆搜尋直到找到全域最佳解為止。範例中將結構最佳化問題轉為數學函數,再利用蜂群演算法對結構系統執行最佳化設計。由數值分析範例之結果 ...

Bi-fidelity conditional-value-at-risk estimation by dimensionally decomposed generalized polynomial chaos expansion

open access: yes, 2022
Digital twin models allow us to continuously assess the possible risk of damage and failure of a complex system. Yet high-fidelity digital twin models can be computationally expensive, making quick-turnaround assessment challenging.

Tile Classification Based Viewport Prediction with Multi-modal Fusion Transformer

open access: yes, 2023
Viewport prediction is a crucial aspect of tile-based 360 video streaming system. However, existing trajectory based methods lack of robustness, also oversimplify the process of information construction and fusion between different modality inputs ...
