摘要：
Based on the virtual disassembly technology extended by virtual reality technology in the field of mechanical design and manufacturing, many experiments do not allow students to operate freely for various reasons, but are not affected in the computer. Since the training of employees in thermal power plants is generally based on the mentoring system, the training period is long and the effect is slow, so the virtual pump is used to model the front pump and build the fault library, including common mechanical faults, electrical fault types and disposal. The way to build the database, so that the new factory personnel can quickly master the system, thus saving manpower training costs. In the design process, 3D MAX, Unity, Visual Studio and other software were used to design the 3D graphics and disassemble the process according to the equipment standard, and the virtual simulation teaching can be combined with the physical equipment.

摘要：
Motivated by cloud servers undertaking heavy encryption of outsourced data for diverse devices, an Economical and High-Quality Encryption Scheme is proposed to alleviate the burden of energy consumption of the servers meanwhile to keep high-quality services. The objective of the scheme is to minimize the cost that combines economy and service quality. For achieving this objective, a two-phase scoring mechanism is proposed. And then based on the above methods and the scoring mechanism, an algorithm achieving the scheme is designed. To evaluate the scheme, some experiments are performed on a heterogeneous platform. The experimental results show that the encryption algorithm can save energy consumption by 47.8% and slightly improve delay rate by 0.93/10000 on average compared with the original one.
摘要：
Encryption plays an important role in protecting data, especially data transferred on the Internet. However, encryption is computationally expensive and this leads to high energy costs. Parallel encryption solutions using more CPU/GPU cores can achieve high performance. If we consider energy efficiency to be cost effective using parallel encryption solutions at the same time, this problem can be alleviated effectively. Because many CPU/GPU cores and encryption are pervasive currently, saving energy cost by parallel encrypting has become an unavoidable problem. In this paper, we propose an energy-efficient parallel Advance Encryption Standard (AES) algorithm for CPU-GPU heterogeneous platforms. These platforms, such as the Green 500 computers, are popular in both high performance and general computing. Parallelizing AES, using both GPUs and CPUs, balances the workload between CPUs and GPUs based on their computing capacities. This approach also uses the Nvidia Management Library (N-VML) to adjust GPU frequencies, overlaps data transfers and computation, and fully utilizes GPU computing resources to reduce energy consumption as much as possible. Experiments conducted on a platform with one K20M GPU and two Xeon E5-2640 v2 CPUs show that this approach can reduce energy consumption by 74% compared to CPU-only parallel AES and 21% compared to GPU-only parallel AES on the same platform. Its energy efficiency is 4.66 MB/Joule on average higher than both CPU-only parallel AES (1.15 MB/Joule) and GPU-only parallel AES (3.65 MB/Joule). As an energy-efficient parallel AES solution, it can be used to encrypt data on heterogeneous platforms to save energy, especially for the computers with thousands of heterogeneous nodes.
摘要：
This paper establishes evaluation indicators of the real estate marketing planning course teaching reform, uses relevant models of extension matter element theory to construct multidimensional extension matter element model of the real estate marketing planning course teaching reform evaluation, and uses cases to carry out empirical analysis. Empirical evidence shows that real estate marketing planning course teaching reform indicators are in line with the current direction of real estate marketing planning courses teaching reform. The extension matter element evaluation method can evaluate complex, intersecting and uncertain real estate marketing planning course teaching reform indicators effectively, comprehensively and objectively, which is an effective evaluation method.

摘要：
In the study, a new method based on the second-order calibration of three-way fingerprints of PAHs（SCTFP） was developed for the source apportionment of urban PM10 for the first time. First, simulated three-way data arrays of GC-MS were used to verify the feasibility of SCTFP. Then, PM10 and pollution source samples were collected during July and August, 2018 in Loudi City, China. After resolving the problems of GC-MS including baseline drift, retention-time shift and unexpected peaks overlapping, chromatographic and mass spectral profiles and concentrations of PAHs were accurately obtained by the second-order calibration of GC-MS data of samples. Last, a contribution matrix of the source to the receptor was estimated according to the obtained concentrations of PAHs. The proposed method was employed to apportion the source contributions to PM10 at five locations and reasonable results were obtained, thus presenting a promising tool for source apportionment of complex ambient particulate matter.
