A New Look at Building Facades as Infrastructure Perspective

Doris Sung

Engineering 2016, Volume 2, Issue 1,   Pages 63-68 doi: 10.1016/J.ENG.2016.01.008

Abstract: However, little is done to design this surface to benefit the public sphere.Instead, the facade of a building performs either as a component that focuses only on the quality of comfortThis essay proposes the rethinking of the building facade as a steward of outdoor pedestrian welfare,and the conception of public health as an added function of the building envelope−a concept thatmay fall into the jurisdiction of public works.

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 3,   Pages 283-289 doi: 10.1007/s11705-009-0272-8

Abstract: It is a pioneering work to use a Markov chain model to study the pedestrian escape route without visibilitystanding, crawling, walking, leaping, jogging, and running) are applied to describe the characteristics of pedestrianBesides, eight main direction changes are used to describe the transition characteristic of a pedestrianAt the same time, this paper analyzes the escape route from two views, i.e., pedestrian pace states andThe research results show that the Markov chain model is more realistic as a means of studying pedestrian

Abstract:

Reforms in public hospitals are among the most important improvements in China’s health careHowever, the reforms that should be implemented in public hospitals are unclear.are provided for the government to reform public hospitals.However, solely increasing this subsidy cannot address the inappropriate incentives of public hospitalsThe most crucial step in setting the direction of reforms in public hospitals in China is transforming

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 1,   Pages 131-140 doi: 10.1631/FITEE.2200128

Abstract: Ensuring the safety of s is essential and challenging when are involved. Classical avoidance strategies cannot handle uncertainty, and learning-based methods lack performance guarantees. In this paper we propose a (HRL) approach for to safely interact with s behaving uncertainly. The method integrates the rule-based strategy and reinforcement learning strategy. The confidence of both strategies is evaluated using the data recorded in the training process. Then we design an activation function to select the final policy with higher confidence. In this way, we can guarantee that the final policy performance is not worse than that of the rule-based policy. To demonstrate the effectiveness of the proposed method, we validate it in simulation using an accelerated testing technique to generate stochastic s. The results indicate that it increases the success rate for avoidance to 98.8%, compared with 94.4% of the baseline method.
