Abstract: A method with which mechanical properties of the interface of the fiber reinforced thermoplastic resin matrix composite material can be improved by conducting grafting on surfaces of materials. A carbon fiber (CF) and a polymethyl methacrylate resin (PMMA) are subjected to interface modification treatment to introduce active carboxyl groups to the surfaces of the materials. Then, hexamethylene diisocyanate (HDI) is used as a coupling layer for connecting the carboxyl groups on the surfaces of the carbon fiber and on the surfaces of the polymethyl methacrylate resin to form a “molecular bridge”. Accordingly, the interface binding force between the resin and the fiber is improved by chemical grafting. A modified carbon fiber reinforced polymethyl methacrylate composite material sample (CF/PMMA) is prepared by a thin film lamination method, and the composite material sample prepared is subjected to a microscopic verification testing of the validity of the method provided in the present disclosure.

Abstract: A deep learning-based method for fusing multi-source urban energy data and a storage medium are provided to perform data fusion on multi-source urban energy data found in big data and perform multi-scale and multimodal information fusion by using a cross-modal transformer, thereby implementing cross-modal mutual fusion of multi-source heterogeneous types of data to obtain a fused feature for prediction of a quantity of energy that will be used in the future and a quantity of energy that needs to be produced. The present disclosure proposes a multi-scale cooperative multimodal transformer architecture to enhance an effect of representation learned from an unaligned multimodal sequence. Not only there is a higher degree of correlation in multi-source urban energy data fusion, but also a system becomes more lightweight.

Abstract: According to a transformer-architecture-based method and system for IoT for and smart control of urban integrated energy, urban integrated energy IoT information acquired by a terminal from different areas is output to a server after being standardized into a sequence signal, where energy demand prediction is performed through learning of a deep learning network configured on the server, a smart control network is configured and built by using the deep learning network, real-time prediction processing is performed on the urban integrated energy IoT information acquired in real time, and a result is uploaded to a workstation for reviewing. Based on the transformer architecture, the deep learning network is combined with a fast Fourier transform algorithm and inverse transform on a sequence, and an FFT-Attention mechanism is proposed. Compared with a conventional transformer architecture, frequency domain information of a sequence is given more emphasis.

Abstract: A server receives a request from a first application to search for retail availability of a specific item near a defined location. The defined location may be provided by the user, of determined by the server. The server performs a search for the specific item in a database storing data records for a plurality of items, wherein the data records are populated by users of the first application. Each data record includes a unique identifier, an item type, a item sub-type, an item description, a retail outlet where the item is available, and the number of likes for the item at particular retail outlets, as posted by other users for the item at the retail outlet. The server generates search results as a list of different retail outlets ranked in descending order by the number of likes for the specific item at those different retail outlets.

Abstract: A nuclear chemistry laboratory adopts In-site Cutting Technique to remove the large-scale glove box contaminated by transuranium compounds. During removal operation, to prevent further spreading of contamination, it is necessary to build an alpha airtight quarantine tent around the glove box that is ready to be cut. Each section of the quarantine tent maintains a stable airflow and sufficient air exchange to meet negative pressure requirements and effectively prevent leak of ? contamination. It is necessary to install a negative pressure ventilation system to assure the operation of the quarantine tent that has a pressure gradient and allows airflow from low contamination area to high contamination area to effectively prevent spreading of ? contamination and also increase the safety for the transuranium contaminated glove box that is not in service.
