Control charts are commonly used tools in statistical process control for the detection of shifts in process parameters. Shewhart-type charts are efficient for large shift values, whereas cumulative sum (CUSUM) charts are effective in detecting medium and small shifts. Control chart use commonly assumes that data are free of outliers and parameters are known or correctly estimated based on an in-control process. In practice, these assumptions are not often true because some processes occasionally have outliers. Monitoring the location parameter is usually based on mean charts, which are seriously affected by violations of these assumptions. In this paper we propose several CUSUM median control charts based on auxiliary variables, and offer comparisons with their corresponding mean control charts. To monitor the location parameter, we examined the performance of mean and median control charts in the presence and absence of outliers. Both symmetric and non-symmetric processes were studied to examine the properties of the proposed control charts to monitor the location parameter using CUSUM control charts. We used different run length measures to study in-control and out-of-control performances of CUSUM charts. Results revealed that our proposed control charts perform much better than the traditional charts in the presence of outliers. A real application of our study was provided using data on concrete compressive strength as it relates to the quality of cement manufacturing.

The rapid development of the third-generation semiconductor materials represented by SiC and GaN offers China a strategic opportunity to realize the independent control over its advanced semiconductor materials and auxiliary materials sector and to ensure the security of relevant industrial systems. In this paper, we analyze the development status of semiconductor materials and auxiliary materials in China and abroad, propose the idea of systematic, upstream–downstream coordinated, and sustainable development, and set the development goals for these materials by 2025 and 2035. To promote the development of advanced semiconductor materials and auxiliary materials in China, we suggest the establishment of a project for realizing independent control over key material and equipment of integrated circuit; a platform that provides integrated tests for SiC and GaN semiconductor materials, auxiliary materials,processes, and equipment; and application demonstration projects for advanced semiconductor materials in the fifth-generation mobile communication, energy internet, and new energy vehicle fields. Demand analysis regarding these projects is conducted and specific project objectives and tasks are proposed correspondingly. To promote the innovative development of the semiconductor industry,China should adhere to government guidance to facilitate the integration of domestic advantageous resources, grasp the “More Than Moore” opportunity of to lay out the next-generation integrated circuit technologies, and construct an innovation chain to further improve the innovation ecology.

Fire design is the basis of quantitative evaluation in performance-based fire design, which includes the determination of fire location and heat release rate (HRR). Take large-scale exhibition hall for example, utilizing fire radiation model and smoke radiation model and combining the simulate result of CFAST 6.0, analysis of fire grown situation is taken with different fire locations in large space. Research reveals: only considering fire radiation, when fire develops in a location of bilateral symmetry, fire grows faster with HRR peak values are larger and the time of attain HRR peak value earlier and duration time are shorter than others. Thereinto, fire grow fastest when fire develops in the location of center symmetry. Moreover, combining fire radiation and smoke radiation, HRR peak values consumedly increases and almost the same in each scenarios. But other rules, which contain fire growth and the correlative time, when considering fire radiation and smoke radiation, is the same as the situation of just considering fire radiation.

In this paper, the novel design mode of human-aided design (HAD) is proposed to replace conventional computer-aided design (CAD). In HAD, computers can automatically complete the whole product design via a new isogeometric topology optimization (ITO), while humans just assist to slightly modify the design to meet requirements. An embedded domain ITO is presented to design complex models with irregular design domains, and editable geometric models of optimized results can be automatically generated based on layered ITO results. Three examples are tested to verify the proposed HAD mode, including a 3D cantilever beam with a regular design domain, an automotive part with an irregular design domain, and a Messerschmitt-Bölkow-Blohm (MBB) beam with a multiscale structure. The results demonstrate that the proposed HAD mode can automatically deliver high-quality optimized models; thus, it has great potential as a revolutionary technology to change the current design mode from CAD to HAD.

For reducing heavy oil thermal cost,development scheme such as producing steam by burning crude oil to achieve heavy oil need to change. Also we need to reduce formation damage, so we launched hot dry rock(HDR) assisted oil recovery feasibility study. HDR assisted oil recovery extracted heat reservoir of underground thermal energy by hot dry rock to reduce oil viscosity and improve oil mobility. The technical support facilities regardless of drilling deep or heavy oil thermal recovery technologies are mature. HDR heat from geotherm in core-mantle boundary, were widely distributed, clean and renewable. Studies have shown that hot dry rock assisted oil recovery technology had strong pertinence and effectively inherited cyclic steam injection and steam drive technology, and technically feasible. So it may promote the development of related technology and is in line with China's basic national policy of saving energy and emission reduction. It is advised that hot dry rock assisted oil recovery pilot test should be carried out firstly in the favorable block.

The integration, open accessing of healthcare data, and the use of artificial intelligence to organize and analyze fragmented medical information can improve medical and health services, promote the level of rational government decision-making, and reduce the inequality in the allocation of medical and health resources. This paper summarizes the current status of technologies and applications of artificial intelligence in the field of medical information semantic fusion and in the field of image analysis, and analyzes current problems and challenges. The first is the standardized representation and structural integration of medical information to merge national and widely-used clinical terminologies, which is key to realizing auxiliary diagnosis based on ‘big data’ artificial intelligent. The second is the use of massive medical knowledge to construct an intelligent diagnosis and treatment model with the ability to combine multimodal data analysis and structured knowledge reasoning. Thus, we propose a national-level healthcare open data cloud platform that can help open up new data markets, improve the integration of healthcare data, and provide the new service of knowledge discovery and services. We also suggest to establish some basic industry standards for medical and health information, to strengthen the research and development of domestic medical devices, to promote the development of intelligent medical devices and smart wearable devices, and to guide the industry to open up new markets on the combination of artificial intelligence and medical devices.

Terahertz (THz) technology is probably best known to the public as a powerful tool for imaging, since it has been applied in security and medical scanning, resulting in numerous impressive images that would be unobtainable using other technologies. With the roll-out of 5G mobile networks, research into 6G wireless communications is heating up. It is envisioned that THz technology will be used for 6G and future wireless communications. In this paper, we review how THz technology has been employed for imaging and wireless communications, identify state-of-the-art developments in the field, and then examine and compare common devices and issues in both applications. The possibility of integrating THz imaging/sensing and wireless communications is considered, and challenges and future perspectives are presented and discussed. It is shown that THz technology is indeed a key enabling technology for both imaging and wireless communications in the future.
