Efficient algorithm and computing tool for shading calculation [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2006
The window is always part of a building envelope. It earns its respect in creating architectural elegance of a building. Despite a major advantage of daylight utilization, a window would inevitably allow heat from solar radiation to penetrate into a ...

Spatial Air Index Based on Largest Empty Rectangles for Non-Flat Wireless Broadcast in Pervasive Computing

ISPRS International Journal of Geo-Information, 2016
In pervasive computing, location-based services (LBSs) are valuable for mobile clients based on their current locations. LBSs use spatial window queries to enable useful applications for mobile clients.

Image thresholding segmentation based on weighted Parzen-window and linear programming techniques

Scientific Reports, 2022
Image segmentation by thresholding is an important and fundamental task in image processing and computer vision. In this paper, a new bi-level thresholding approach based on weighted Parzen-window and linear programming techniques is proposed to use in ...

Element Distinctness, Frequency Moments, and Sliding Windows

, 2013
We derive new time-space tradeoff lower bounds and algorithms for exactly computing statistics of input data, including frequency moments, element distinctness, and order statistics, that are simple to calculate for sorted data.

Comparing in- and out-of-sample approaches to variance decomposition-based estimates of network connectedness an application to the Italian banking system

Quantitative Finance and Economics, 2018
We use methods that exploit variance decompositions from standard (rolling window) estimates of VAR(p) models to obtain estimates of network connectedness and perform an empirical comparison of the results derived under two alternative approaches: To ...

Efficient estimation of AUC in a sliding window

, 2019
In many applications, monitoring area under the ROC curve (AUC) in a sliding window over a data stream is a natural way of detecting changes in the system. The drawback is that computing AUC in a sliding window is expensive, especially if the window size

Divide, Conquer and Combine: Hierarchical Feature Fusion Network with Local and Global Perspectives for Multimodal Affective Computing

Annual Meeting of the Association for Computational Linguistics, 2019
We propose a general strategy named ‘divide, conquer and combine’ for multimodal fusion. Instead of directly fusing features at holistic level, we conduct fusion hierarchically so that both local and global interactions are considered for a comprehensive

Critical Window for Connectivity in the Configuration Model [PDF]

Combinatorics, probability & computing, 2016
We identify the asymptotic probability of a configuration model CM n (d) producing a connected graph within its critical window for connectivity that is identified by the number of vertices of degree 1 and 2, as well as the expected degree.
