Healthy and walking friendly campus community in cold areas: taking the community of Harbin Institute of Technology as an example

Abstract

The cold weather in winter in severe cold areas has brought many adverse effects on the local social and economic development. As an essential connecting element between buildings, the warm skyway not only provides convenient travel conditions for the community but also expands the functional richness of public space and promotes a healthy life. The core of this study is to build a walking system with good walking comfort and promote healthy activities by constructing a warm skyway to renew university campuses in cold regions. Harbin is a typical cold region city in Northeast China. Taking the community of Harbin Institute of technology as an example, using the GIS platform, POI data, OSM map, and other open-source data, through the methods of vector analysis, nuclear density analysis, correlation analysis, and mixing degree analysis, this paper studies the location of the warm skyway and the functional transformation of the connecting layer, and puts forward the planning strategies of the warm skyway system in the university campus community in severe cold areas, to provide a basis for the construction of a healthy walking-friendly community in cold cities.

Evaluation of Aging-Friendly Public Spaces in Old Urban Communities Based on IPA Method—A Case Study of Shouyi Community in Wuhan

“…The goal of this study is to deeply understand the importance and satisfaction evaluation of aging-friendly factors in community spaces for the elderly and to analyze the aging-friendly status of old communities. We used the method employed in the literature, collecting evaluation factors from related papers on aging-friendly evaluations [25,26]. Based on scholar evaluations of aging-friendly content, and combined with preliminary observations, we initially determined the evaluation factors.…”

Analysis of oil film flow characteristics and lubrication performance of thrust bearing of 1000MW Hydraulic Turbine Unit

“…Li et al [19] proposed that the oil film thickness and working temperature of thrust bearings were important factors affecting their lubrication performance and bearing capacity, and observed the formation, change and rupture process of the oil film through experiments, and studied the flow type within the oil tank. Subsequently, Lu et al [20] numerically calculated the internal flow field of the oil tank, and analysed the influence of the support method of the pads and the cooling structure of the lubricant on the stability of the bearing. It was concluded that the wedge gap was superior to the average gap and was less prone to burned pads.…”
