A non-Lambertian photometric stereo under perspective projection Research Articles

Min Li, Chang-yu Diao, Duan-qing Xu, Wei Xing, Dong-ming Lu,liminlim@126.com,dcy@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 8,   Pages 1119-1266 doi: 10.1631/FITEE.1900156

Abstract: Under the assumption, non-Lambertian is a highly non-linear problem. In this study, we present an optimized framework for reconstructing the surface normal and depth with non-Lambertian reflection models under . By decomposing the images into diffuse and specular components, we compute the surface normal and reflectance simultaneously. We also propose a variational formulation that is robust and useful for surface reconstruction. The experiments show that our method accurately reconstructs both the surface shape and reflectance of colorful objects with non-Lambertian surfaces.

Impact of household transitions on domestic energy consumption and its applicability to urban energy planning

Benachir MEDJDOUB, Moulay Larbi CHALAL

Frontiers of Engineering Management 2017, Volume 4, Issue 2,   Pages 171-183 doi: 10.15302/J-FEM-2017029

Abstract: The household sector consumes roughly 30% of Earth’s energy resources and emits approximately 17% of its carbon dioxide. As such, developing appropriate policies to reduce the CO emissions, which are associated with the world’s rapidly growing urban population, is a high priority. This, in turn, will enable the creation of cities that respect the natural environment and the well-being of future generations. However, most of the existing expertise focuses on enhancing the thermal quality of buildings through building physics while few studies address the social and behavioral aspects. In fact, focusing on these aspects should be more prominent, as they cause between 4% and 30% of variation in domestic energy consumption. Premised on that, the aim of this study was to investigate the effect in the context of the UK of household transitions on household energy consumption patterns. To achieve this, we applied statistical procedures (e.g., logistic regression) to official panel survey data comprising more than 5500 households in the UK tracked annually over the course of 18 years. This helped in predicting future transition patterns for different household types for the next 10 to 15 years. Furthermore, it enabled us to study the relationship between the predicted patterns and the household energy usage for both gas and electricity. The findings indicate that the life cycle transitions of a household significantly influence its domestic energy usage. However, this effect is mostly positive in direction and weak in magnitude. Finally, we present our developed urban energy model “EvoEnergy” to demonstrate the importance of incorporating such a concept in energy forecasting for effective sustainable energy decision-making.

Actor–Critic Reinforcement Learning and Application in Developing Computer-Vision-Based Interface Tracking Article

Oguzhan Dogru, Kirubakaran Velswamy, Biao Huang

Engineering 2021, Volume 7, Issue 9,   Pages 1248-1261 doi: 10.1016/j.eng.2021.04.027

Abstract:

This paper synchronizes control theory with computer vision by formalizing object tracking as a sequential decision-making process. A reinforcement learning (RL) agent successfully tracks an interface between two liquids, which is often a critical variable to track in many chemical, petrochemical, metallurgical, and oil industries. This method utilizes less than 100 images for creating an environment, from which the agent generates its own data without the need for expert knowledge. Unlike supervised learning (SL) methods that rely on a huge number of parameters, this approach requires far fewer parameters, which naturally reduces its maintenance cost. Besides its frugal nature, the agent is robust to environmental uncertainties such as occlusion, intensity changes, and excessive noise. From a closed-loop control context, an interface location-based deviation is chosen as the optimization goal during training. The methodology showcases RL for real-time object-tracking applications in the oil sands industry. Along with a presentation of the interface tracking problem, this paper provides a detailed review of one of the most effective RL methodologies: actor–critic policy.

Paths for Carbon Peak and Carbon Neutrality in Transport Sector in China

Li Xiaoyi, Tan Xiaoyu, Wu Rui, Xu Honglei, Zhong Zhihua, Li Yue, Zheng Chaohui, Wang Renjie, Qiao Yingjun

Strategic Study of CAE 2021, Volume 23, Issue 6,   Pages 15-21 doi: 10.15302/J-SSCAE-2021.06.008

Abstract:

Peaking carbon dioxide emissions and achieving carbon neutrality is a major strategic decision taken by China and it brings significant pressure and challenges to the transport sector. Peaking carbon emissions is an important direction for the highquality development and green transformation of the transport sector. This study analyzes the status quo of green development and carbon emission in China’s transport sector and identifies the challenges for achieving the carbon peak and carbon neutrality goals in the transport sector. The overall idea is to peak carbon emissions actively and steadily by implementing categorized policies, combining short- and long-term goals, controlling carbon emission increment, and adjusting the current emission structure. An overall path for carbon reduction in the transport sector at different stages is proposed. Furthermore, we summarize several key measures to achieve carbon peak and carbon neutrality in the transport sector: (1) optimizing the transport structure, (2) promoting the energy efficiency of transport equipment, (3) popularizing low-carbon transport equipment, (4) improving the traffic organizing efficiency, and(5) encouraging low-carbon travel modes.
