This paper studies the simultaneous fault diagnosis of the main reducer in the automobile transmission system assembly based on vibration signals. A simultaneous fault diagnosis model based on Paired Relevance Vector Machine (Paired-RVM) is proposed for the simultaneous fault of the main reducer, and each binary sub-classifier is trained with single fault samples and then fused by a pairing strategy. With F-measure as a measurement indicator of diagnosis precision, the threshold set DThreshold is used to train a threshold optimization algorithm so as to generate the optimal decision threshold, thus converting the probability output generated by the classification model into the final simultaneous fault mode. A contrast experiment is made between Paired-RVM and some commonly used supervised learning models of SVM, ELM and KELM, and the experimental results show that the performance of Paired-RVM proposed in this paper is superior to that of other models in simultaneous fault diagnosis and single fault diagnosis, verifying the effectiveness of the proposed method.

As a most important part of students majoring in computer science related areas, experiments contribute to not only better understanding the theoretical knowledge but also enhancing the ability of hands-on. However, traditional laboratories require a high-cost investment on both site and equipment, especially experiments of computer network. In order to address these problems, we design a virtual experiment platform based on OpenStack which enables users to select virtual experiment resources like PC, router and servers as well as building network topology and accessing these devices. Our platform renders teachers and students a perfectly functional experiment system making it possible to do experiments in classroom and dormitory which guarantees usability and simplicity for students to better practice.

Medical laryngoscope has been widely used in medical diagnosis, but traditional laryngoscope still has many deficiencies, especially in the ability of data storage and processing. Therefore, in this paper, the Wireless HD Laryngoscope System combines the Hadoop cloud platform. The images and video information collected by laryngoscope can real-time transmission to the remote client through streaming server and be saved in Hadoop cloud platform. In consequence, the client can replay history video at any time and any place.

Spatial information network is an important part of the integrated space-terrestrial information network, its bearer services are becoming increasingly complex, and real-time requirements are also rising. Due to the structural vulnerability of the spatial information network and the dynamics of the network, this poses a serious challenge to how to ensure reliable and stable data transmission. The structural vulnerability of the spatial information network and the dynamics of the network brings a serious challenge of ensuring reliable and stable data transmission. Software Defined Networking (SDN), as a new network architecture, not only can quickly adapt to new business, but also make network reconfiguration more intelligent. In this paper, SDN is used to design the spatial information network architecture. An optimization algorithm for network self-healing based on SDN is proposed to solve the failure of switching node. With the guarantee of Quality of Service (QoS) requirement, the link is updated with the least link to realize the fast network reconfiguration and recovery. The simulation results show that the algorithm proposed in this paper can effectively reduce the delay caused by fault recovery.

High quality atomically thin nanomaterials synthesis by Chemical Vapor Deposition method is a research area in current development. The resulting material depends intimately on the parameters used for the growth, with each material having its own unique process space. In this work, a Modular Communication System has been designed and developed to solve challenges in the synthesis of a wide variety of nanomaterials. Through this modular automation approach, reducing time and cost to optimize material properties, facilitate the data analysis for a more comprehensive understanding of how the process parameters affect the growth, crystallinity and thickness of the synthesized nanomaterials.

Based on the iterative optimization method of updating the teaching idea, optimizing the curriculum system, strengthening the schoolenterprise cooperation and improving teachers' qualities, this paper puts forward an interactive training model, which is suitable for training domestic software engineering masters. The training model could cultivate compound application talents, who are good at theory and practice at the same time and with abilities to analyze independently and solving practical problems.

The appearance of MOOCs brings a lot of attentions. Although MOOCs provide the people with more learning opportunities and conditions, there are some disadvantages, such as the practice of the skills and the difficulties in the understanding of the key notes due to the lack of the interaction between the teacher and the students. Virtual reality technology brings the chance to solve these problems. This paper presents the software-based virtual experiments of MOOCs to solve the difficulties in the understanding of the key notes in MOOCs by visualizing the abstract problem with virtual reality technology.
