Spatial Configurations and Walkability Potentials. Measuring Urban Compactness with Space Syntax

open access: yesSustainability, 2021
This contribution demonstrates how space syntax methods on various scale levels can be used to identify and describe the spatial features of a compact city. Firstly, the term urban compactness is discussed.

A model test study of the instability of loess fill slope under different compactness

open access: yesShuiwen dizhi gongcheng dizhi, 2022
Loess fill slope is prone to landslide under the condition of rainfall infiltration. The influence of compaction degree under rainfall infiltration on the deformation and failure mechanism and the instability mode and sliding mechanism of loess fill ...

A class of operator related weighted composition operators between Zygmund space [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
Let $\mathbb {D}$ be the open unit disk in the complex plane $\mathbb{C}$ and $H(\mathbb{D})$ be the set of all analytic functions on $\mathbb{D}$. Let $u, v\in H(\mathbb{D})$ and $\varphi$ be an analytic self-map of $\mathbb{D}$.

Impact of the Rotation and Compactness of Progenitors on the Mass of Black Holes [PDF]

open access: yesAstrophysical Journal, 2019
We investigate the impact of stellar rotation on the formation of black holes (BHs) by means of our population synthesis code sevn. Rotation affects the mass function of BHs in several ways.

60Co Irradiation Influences Germination and Phenotype of Three Pavonia Species

open access: yesHortScience, 2020
The genus Pavonia is one of the largest genera in the Malvaceae species; it is mainly distributed in South America. Three species of Pavonia were identified based on different flower colors and potential for landscape use in the southeastern United ...

Toeplitz operators between large Fock spaces in several complex variables

open access: yesAIMS Mathematics, 2022
Let $ \omega $ belong to the weight class $ \mathcal{W} $, the large Fock space $ \mathcal{F}_{\omega}^{p} $ consists of all holomorphic functions $ f $ on $ \mathbb{C}^{n} $ such that the function $ f(\cdot)\omega(\cdot)^{1/2} $ is in $ L^p(\mathbb{C ...

$\mathcal{G}$ -Softmax: Improving Intraclass Compactness and Interclass Separability of Features [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2019
Intraclass compactness and interclass separability are crucial indicators to measure the effectiveness of a model to produce discriminative features, where intraclass compactness indicates how close the features with the same label are to each other and ...

Image Saliency Detection Combining Sparse Reconstruction and Compactness

open access: yesJisuanji kexue yu tansuo, 2020
Aiming at the problem that existing image saliency detection algorithms can't correctly detect salient objects in complex environments, this paper proposes a method combining sparse reconstruction error and the compactness of image salient regions to ...

Unsupervised Feature Selection for Histogram-Valued Symbolic Data Using Hierarchical Conceptual Clustering

open access: yesStats, 2021
This paper presents an unsupervised feature selection method for multi-dimensional histogram-valued data. We define a multi-role measure, called the compactness, based on the concept size of given objects and/or clusters described using a fixed number of

A Compact and High-Precision Three-Degree-of-Freedom Grating Encoder Based on a Quadrangular Frustum Pyramid Prism

open access: yesSensors, 2023
A compact and high-precision three-degrees-of-freedom (DOF; X, Y, and Z directions) grating encoder based on the quadrangular frustum pyramid (QFP) prisms is proposed in this paper to solve the insufficient installation space problem of the reading head ...
