Abstract:

A lateral displacement control method of a moving web using an offset-pivot guide system for intermittent web transportation is presented in this paper. The dynamics model of the offset-pivot guide system is investigated, and the factors resulting in the lateral displacement of the web are researched and analyzed. In the case of intermittent web transportation, iterative learning control (ILC) is adopted to eliminate the periodic disturbance. Simulations show that the iterative learning control method adopted is very effective to resist the lateral displacement of the web by using the offset-p

Abstract Kiloparsec-scale dual and offset active galactic nuclei (AGNs) are signposts of accreting supermassive black holes (SMBHs) triggered during late-stage galaxy mergers, offering crucial insights into the coevolution of SMBHs and galaxies. However, robustly confirmed systems at high redshift (e.g., z > 1) are scarce and biased toward the most luminous and unobscured systems. In this study, we systematically search for kiloparsec-scale (projected separation <15 kpc) dual and offset AGNs around 571 moderate-luminosity, X-ray-selected AGNs, including the obscured population, utilizing

Abstract:

The manufacture of printed electronics by roll-to-roll printing machine requires more accurate register performance than conventional media printing technology. Moreover, high drying temperature and long drying time to sinter the inks can induce the substantial changes in the length of the substrate and consequently register errors. Among the roll-to-roll printing methods, the gravure one, despite its relatively fast productivity and fine-line printing capacity, has difficulty in achieving the required register specifications for printed electronics because of the dependence of the register co

Abstract:

Lateral or cross-machine direction (CD) web movement in printing or converting can cause problems such as misregistration, wrinkles, breaks, and folder issues. The role of paper properties in this problem was studied by measuring lateral web positions on commercial printing presses and on a pilot-scale roll testing facility (RTF). The findings clearly showed that CD profiles of machine direction (MD) tension were a key factor in web stability. Uneven tension profiles cause the web to move towards the low-tension side. Although extremely nonuniform tension profiles are visible as bagginess, mor

Abstract:

Users of peer production web sites differ greatly in their activity levels.A small minority are engaged contributors, while the vast majority are only casual surfers. The casual users devote little effort to evaluating the site's content and many of them visit the site only once. This churn poses a challenge for sites attempting to gauge user interest in their content. The challenge is especially severe for sites focusing on content with subjective quality, including movies, music, restaurants and items in other cultural markets. A key question is whether content evaluation should use opinions

Abstract:

Difference in dot gain using various additives to the damping solution was investigated on two offset web presses. Dot gain was measured using a densitometer and calculated considering CIE L*a*b* coordinates. It was found that while using a non alcohol additive instead of the alcohol one, dot gain became smaller and printing stability was lower. Changes in dot gain depend on the ink that may vary in colours. The influence of changes in dot gain on the colour was determined. Besides, it was found that differences in colour were unacceptable in many cases.

Abstract:

Accurate subsurface characterization is vital for hydrocarbon exploration and the energy transition. Full-waveform inversion (FWI) potentially provides a complete data model by fully simulating elastic wave propagation in 3D, but it is computationally demanding. Linear amplitude variation with offset (AVO) inversion is computationally efficient by deploying a 1.5D data model but is limited by simplifying assumptions like primary reflections only. This study introduces elastic wave-equation-based AVO (WEB-AVO), which combines the efficiency of AVO inversion with the physical accuracy of FWI. Ad

Even though managing raw materials using Microsoft Excel is quite good, the company still faces difficulties in preparing raw material usage reports. The administration had to create daily reports and check data compliance manually, which resulted in inefficiencies. Therefore, a web-based raw material inventory management information system is needed to assist inventory management.

Paper tension is the most important control parameter in roll material production that directly impacts the printing quality of the web offset. Based on the closed-loop paper tension control theory, by conducting a research into the simulation of paper tension control system with MATLAB/SIMULINK, presented the closed-loop control diagram about the paper tension control system. Under different control parameter, the value of the overshoot, respond speed and residual of the system varies. As a result, the quantitative research on the simulation of the system offers a valid means in improving the

Based on the dynamic model of fold mechanism, the nonlinear dynamics responses and the chaos movement in pair are studied. Used the performance parameters and dynamics response sensitivities as the goal values, the robust design model is established. By the robust design model, the nonlinear dynamic responses and chaos phenomenon can be under controlled in the same clearance degree. In this way, the perf
