Based on the CAE analysis technology, possible defects of the sheets in the forming process are accurately simulated and predicted, and the method of eliminating defect is found. The results of the analysis not only improve the work efficiency, shorten the design and manufacturing cycle of the mold, but also provide a strong support for the design of mold and the development of the technology program. At the same time, the calculation results are consistent with the actual situation by using Dynaform software to simulate the results. The accuracy and the reliability of the calculation results by using the numerical simulation technology is validated.

The indoor scene accurate recognition can provide valuable environmental information for location based services and context-aware applications. In this paper, we proposed a lightweight indoor scene recognition algorithm. It adopts the quick barometric pressure change to detect indoor floor transition, which is then used to judge the user is in buildings. Because pressure observation is independent of the smartphone placement, the proposed indoor scene recognition algorithm is ubiquitous and robust. Real experimental results demonstrate that the proposed algorithm can accurately determine the user is in indoor scene whenever a floor transition happens with more than 98.8% accuracy and less than 10mW power consumption.

Road Section with high rate of bridge and tunnel of freeway is the potential high risk section of safety and efficiency. This paper focuses on the traffic operation risk assessment of Road Section with high rate of bridge and tunnel of freeway. Firstly, the average speed and coefficient of variation of speed are selected as the traffic operation risk index and treated as the independent variables. Besides, average risk level index is built as the dependent index. Then the multivariate linear traffic operation risk assessment model is established. Take the Ma-Zhao Freeway in Yunnan as the demonstration road, traffic simulation is conducted. Using the output data of simulation, multiple linear regression is applied to estimate the coefficients of traffic operation risk assessment model of Road Section with high rate of bridge and tunnel of freeway. Finally, according to the cumulative frequency curve of average risk level index, traffic operation risk classification standard of road section with high rate of bridge and tunnel of freeway is established.

Android app repackaging has become a serious problem currently. To protect apps from tampering, code obfuscation, watermarking and other techniques have been designed. However, most of these approaches could only provide inadequate protection. Meanwhile, it is possible to achieve remote tamper-resistance in recent, especially for networking apps, with the development of cloud computing technology and the spread of networks. In this paper, we propose a novel remote protection mechanism for mobile apps in cloud computing environments. In the proposed mechanism, the app should download and execute some code from the cloud when some important function is called. Tamper proofing code which could check the app is tampered or not is embedded in the downloaded code. Furthermore, the code can only run correctly one time and is continuous changing, which makes it difficult for an adversary to analyze and modify.

An adjustable foaming machine that consisted of air feeding system, liquid feeding system, foaming device, and control system was designed to satisfy various demands on foam density and foam diameter in the preparation of foam concrete. The air-liquid ratio was adjusted by controlling the foaming liquid flow, and the adjustment of foam density was achieved. An adjustable single-foam tube structure was adopted to realize the controls of foam density and pore size by adjusting the packing density of the foaming medium in the foaming tube. By using the single chip as the digital processing core, the communication between single chip and frequency converter was established through the RS485 interface, thereby realizing the automatic control in the working process of the adjustable foaming machine. The experimental result indicated that the foaming process of this machine was stable and highly efficient, and foam density and foam diameter were easy to adjust and control, which improved the usability.
