“…Models based on data (data-driven, back-box) do not require a detailed mathematical-physical description, but good quality data. There are also methods for combining empirical and physical models [40,41]. Quantitative interpretation of remote measurements of radiation spectra is a typical example of the inverse problem in indirect measurements [42].…”

The article presents a method for determining the content and temperature on the basis of spectra from remote measurements. The technique uses measurements of a high resolution radiation spectrum that allows the visibility of the individual rotational lines of gases such as CO2, used here in the range of 2470-2495 cm −1 . At the same time a new algorithm is applied of pre-processing the spectrum, involving the use of multiple ratios of intensity at several wavenumbers as input to an inverse model based on neural networks. Due to it, the dimensionality of the input can significantly be reduced. Additionally, the data interpreted do not have to be measured in units of spectral radiance. Thus only the calibration of the sensitivity of the spectrometer at various wavelengths is required. The neural models were constructed on the basis of data from the simulation. The proposed method works with a uniform layer of radiating gas for determining the temperature and CO2 content. For a non-uniform layer it is possible to determine the line-of-sight temperature profile and average gas content. The method can be extended to different spectral ranges and to other gases present in substantial quantities in the exhaust gases of various processes.

Cylindrical hydraulic dampers used to reduce impacts and vibrations typically have linear strokes. In this study, a new arc-shaped stroke-type origami hydraulic damper with a nonlinear damping performance was proposed. By examining the damping effect of the origami hydraulic damper, the damping force was found to be proportional to the square of the motion velocity. A nonlinear dynamics governing equation was established using the derived formula for the damping force of the origami hydraulic damper, and a numerical analysis using the Runge–Kutta method was established. An impact test device with an arc-shaped stroke was developed, and the error between the numerical analysis value of the impact displacement and the measured experimental value was confirmed to be sufficiently small. An impact verification experiment confirmed that the damping effect of the origami hydraulic damper increases with the input energy of the impact. By varying the diameter of the orifice hole, which is an important design factor for an origami hydraulic damper, the damping effect of the origami hydraulic damper was found to increase as the diameter of the orifice hole decreased. To examine the effect of the type of hydraulic oil inside the origami hydraulic damper, water and edible oil were used to conduct impact verification experiments, and it was found that the effect on the impact damping effect was relatively small.

With the present gap between engineering design and analysis, designers are often hindered in their efforts to explore design alternatives and ensure product robustness. This paper is devoted to parameter constraint graph approach-based dynamic information association and integration between the design model and analysis model. After the description of the gap between design and analysis is analyzed, the modeling and representation method of the product parameter constraints model are proposed. With the help of a product virtual prototyping element model, it can be simplified to a product parameter constraint graph to support an integrated model for multidisciplinary virtual prototyping of complex products. An integrated design and analysis method based on the parameter constraint graph approach is proposed based on the parameterized design method for analysis. The decoupling method of parameter constraints for multidisciplinary virtual prototyping is also discussed in detail in five steps. The integrated design and analysis of an automatic pipe racking robot in an offshore platform are given as an example, which demonstrates that the methodology is obviously helpful in improving the associability of design–analysis models.
