Research on the Management Mode of Project Archives from the Perspective of Project Management
By analyzing present situation and the characteristics of engineering archives management, analyses the engineering archives management the lack of support for the project management; The possibility of application of engineering files in project management is analyzed emphatically. Finally, combining with the actual situation, the paper gives the construction measures of the project archives management mode from the perspective of project management
Reform Exploration for Safety Course System of Oil and Gas Storage and Transportation Facilities
In recent years, the safety of oil and gas storage and transportation facilities has been paid more attention by the state and enterprises due to frequent accidents. The oil and gas storage and transportation facilities safety courses in China University of Petroleum (Beijing) includes “Engineering mechanics”, “Strength design of pipelines and tanks” and “Safety and integrity management of oil and gas storage and transportation facilities”. The three courses lack relevance and the teaching mode is too rigid, resulting in students losing their initiative in learning. If students can’t use the knowledge flexibly, it will affect the achievement of the objectives of the training program. Therefore, oil and gas storage and transportation facilities safety courses are reformed, training plans are adjusted and teaching methods are improved. The practice shows that the reform enriches the teaching content, improves the teaching quality, stimulates classroom activity and gets a good evaluation of students. The reform of safety courses has a certain significance for cultivating compound talents who have the ability to solve practical problems in engineering
Change is Everywhere: Single-Temporal Supervised Object Change Detection in Remote Sensing Imagery
For high spatial resolution (HSR) remote sensing images, bitemporal
supervised learning always dominates change detection using many pairwise
labeled bitemporal images. However, it is very expensive and time-consuming to
pairwise label large-scale bitemporal HSR remote sensing images. In this paper,
we propose single-temporal supervised learning (STAR) for change detection from
a new perspective of exploiting object changes in unpaired images as
supervisory signals. STAR enables us to train a high-accuracy change detector
only using \textbf{unpaired} labeled images and generalize to real-world
bitemporal images. To evaluate the effectiveness of STAR, we design a simple
yet effective change detector called ChangeStar, which can reuse any deep
semantic segmentation architecture by the ChangeMixin module. The comprehensive
experimental results show that ChangeStar outperforms the baseline with a large
margin under single-temporal supervision and achieves superior performance
under bitemporal supervision. Code is available at

Development Trend of Global Green Building Materials Industry Based on Patent Analysis
Using the incopat intelligence platform, the development status of the current green building materials was analyzed from the perspectives of IPC technology composition, patent licensing, patent transfer, patent applications, and patent types. It is concluded that the global green building materials industry is unbalanced in development, and it is necessary to strengthen industrial exchanges and development between countries, to jointly promote and achieve a win-win situation; Despite the high number of patents in China, the patent translation rate of Chinese universities and research institutes is relatively low, and the government should establish a communication platform between industry, universities, and research institutes to gain an in-depth understanding of market demand, which would help to patent transfer
Crossover between Weak Antilocalization and Weak Localization of Bulk States in Ultrathin Bi2Se3 Films
We report transport studies on the 5 nm thick Bi2Se3 topological insulator
films which are grown via molecular beam epitaxy technique. The angle-resolved
photoemission spectroscopy data show that the Fermi level of the system lies in
the bulk conduction band above the Dirac point, suggesting important
contribution of bulk states to the transport results. In particular, the
crossover from weak antilocalization to weak localization in the bulk states is
observed in the parallel magnetic field measurements up to 50 Tesla. The
measured magneto-resistance exhibits interesting anisotropy with respect to the
orientation of B// and I, signifying intrinsic spin-orbit coupling in the
Bi2Se3 films. Our work directly shows the crossover of quantum interference
effect in the bulk states from weak antilocalization to weak localization. It
presents an important step toward a better understanding of the existing
three-dimensional topological insulators and the potential applications of
nano-scale topological insulator devices
