Electronic jacquard control system is the core technology of tufted carpet equipment, whose dynamic characteristics determines the quality of tufted carpet surface(the roughness、the level of loop transition phenomenon).In this paper, the structure of jacquard control system is analyzed. And the concept of roughness of carpet surface is given. Its evaluation model is established. Through analysis of structure, we point out that the key factor affecting the quality of carpet surface is signal acquiring unit which is investigated in this paper. We analyze the characteristics of system and the quality of the carpet surface, also establish the model of relationship between the synchronous sampling frequency of stepper motor and the height of carpet loop. Using this simulation model, we get the optimal synchronous sampling frequency of stepper motor to ensure the quality of carpet surface, also provide a theoretical basis for the design of control system.

AbstractLiver fibrosis occurs in response to any etiology of chronic liver injury. Lack of appropriate clinical intervention will lead to liver cirrhosis or hepatocellular carcinoma (HCC), seriously affecting the quality of life of patients, but the current clinical treatments of liver fibrosis have not been developed yet. Recent studies have shown that hypoxia is a key factor promoting the progression of liver fibrosis. Hypoxia can cause liver fibrosis. Liver fibrosis can, in turn, profoundly further deepen the degree of hypoxia. Therefore, exploring the role of hypoxia in liver fibrosis will help to further understand the process of liver fibrosis, and provide the theoretical basis for its diagnosis and treatment, which is of great significance to avoid further deterioration of liver diseases and protect the life and health of patients. This review highlights the recent advances in cellular and molecular mechanisms of hypoxia in developments of liver fibrosis.

To test the accuracy of image motion compensation of space camera, the moving target simulator was developed according to the principle of relative motion. As the core controller, PIC microcontroller controls DC motor to drive photoetching turntable rotating to simulate the relative linear velocity between ground target and aircraft, and the rotation motion is divided into uniform velocity rotation and sinusoidal velocity rotation. Furthermore, the simulation of drift angle of aircraft was realized by controlling stepper motor to drive the photoetching turntable deflecting, and the deflection includes uniform deflection, sinusoidal velocity deflection and specified angle positioning. The design of the hardware and software of control system has been completed and tested, and the experiment results show that the control system has high control precision and meets the design requirements.

The teaching quality is the core of sustainable development in colleges and universities. The constructing scientific and reasonable teaching quality evaluation system is the key of teaching quality evaluation. This paper takes the quality of graduates as the core content, establishes a results-oriented teaching quality evaluation system in colleges and universities, and finds that the academic level of graduates and the level of competition in career selection are two quantitative dimensions reflecting the quality of graduates. Based on this, this paper establishes the evaluation model of the developmental potential index and gives the reference of the norm of teaching effect evaluation for self-evaluation. Finally, this paper discusses the components of graduate quality and the way to construct the evaluation system.

This article is dedicated to examination of mass protests that unfolded in Iraq since the second half of 2019 until the beginning of 2020 and involved even northern part of the country (with prevailing Kurdish population). The core demand of protesters in the Arab part of the country consisted in amendment of the existing administrative system (“Muhasasa"), which issued quotas for the representatives of ethnic and religious groups of the country (Shiite and Sunni Arabs, and Kurds). Separate protests were also recorded in the Iraqi Kurdistan. The novelty of this research consists in examination of Iraqi protests at the present state, as well as from the perspective of relations between the central government of Iraq and Kurdish Autonomy. The conclusion is made that the key factor of protests consists in dissatisfaction of population with the quality of rendered services, low effectiveness of government apparatus, and high level of corruption. Although there is no direct correlation between protests in northern and southern parts of the country, the very fact of disturbances among the Kurds testifies to the existence social tension in northern Iraq. Theoretically, neglecting the demands of Arab population may lead to the proliferation of protests across the country.

Scale Integration

With the large-scale integration of fracturing unit's on-site construction, traditional industrial buses are increasingly unable to meet the requirements for the quantity transmission between various equipment in large-scale fracturing units, and different models of different equipment manufacturers cannot cooperate with each other as there are "Islands of information" in the control system. This article uses industrial Ethernet as the physical medium for data transmission. In addition, different equipment manufacturers use OPC as the core technology of the fracturing unit control system network, and set up an intelligent fracturing unit control system, so that the control network can quickly, accurately, and safely control the fracturing truck control system. The sand truck control system monitors and analyzes, saves, and prints the construction data in the vehicle instrument. At the same time, the network control system uses the vehicle instrument as the core of the network. It can control fracturing vehicles from different manufacturers. The sand mixer truck performs network control, which effectively avoids incompatibilities between various equipment manufacturers at the construction site.
