Published: March 2022

Unsaturated polyester resin (UPR) condensate water contains biodegradable organic compounds, including those that create unpleasant odor. Those odors can adversely impact the environment, human health, and, most of all, the uncomfortably. It is important to identify odor-originated chemical compounds to propose a suitable treatment. In this study fractional distillation method to separate volatile organic compounds (VOCs) from UPR condensate water is applied. Fourier-transform infrared spectroscopy (FTIR) and gas chromatography with mass spectroscopy (GC - MS) was used to examine the chemical compounds in URP condensate water. The results showed that unpleasant odors came from the first distillated fraction of URL condensate water, and its composition suggested potential odor compounds of propanoic acid.

В данной работе решаются обратные задачи сейсморазведки в средах с однородно ориентированными трещиноватыми включениями с применением сверточных нейронных сетей. Выбор данного вида нейронных сетей определен большой размерностью массива данных. Построение обучающей выборки из прямых задач для обучения нейронной сети осуществляется с помощью математического моделирования. Для численного решения прямых задач был взят сеточно-характеристический метод на неструктурированных сетках. Выбор численного метода обусловлен волновой природой изучаемых динамических процессов, которая хорошо учитывается сеточно-характеристическим методом. Данный подход хорошо зарекомендовал себя при построении корректных вычислительных алгоритмов для граничных и контактных условий, в частности, для задания дискретного массива трещин. Целью работы является определение характеристик одиночной трещины и пластов таких трещин. Была успешно решена обратная задача сейсморазведки для пласта трещин с шестью неизвестными параметрами: высота и угол наклона трещин, плотность расположения трещин, горизонтальная протяженность пласта и его пространственное положение в 2D. В процессе обучения нейронной сети и распознавания элементов валидационной выборки, помимо данных о скоростях колебаний в массиве сейсмических данных, на вход сети также подавался их частотный спектр.
In this paper, we solve inverse problems of exploration seismology in rocks with uniformly oriented fractured inclusions using convolutional neural networks. This type of neural network was chosen due to the large dataset. We used simulation to build a neural network training sample from the direct problem results. For the numerical solution of direct problems, a grid-characteristic method was applied to unstructured meshes. This numerical method was used since the studied dynamic processes are of wave nature, which is very suitable for the grid-characteristic method. This approach is proven in building correct computational algorithms for boundary and interface conditions, in particular, for defining discrete fracture arrays. The problem statement is to determine the characteristics of a single fracture and layers of such fractures. The inverse exploration seismology problem for a fractured layer with six unknown parameters was successfully solved. These parameters are the height and angle of inclination of the fractures, the density of the fractures, the horizontal extent of the formation, and its 2D position. The vibration velocities in the seismic data array and the frequency spectra were inputs for the neural network training and validation sample recognition.

Published: March 2022

In designing a truss cantilever structure with a predetermined long span, it will certainly look for a model of long-span structure with a profile that is able to withstand the given load. This can be done by planning a model of the pratt truss long-span structure. The main purpose of this final task is to produce a design of a long-span cantilever structure that is part of a unique building using a pratt truss model. The long-span pratt truss cantilever structure is analyzed using the MDSolids v.4.1.0 program to compute the inner forces working on each component of the designed frame structure, while the STAAD Pro Connect v.22 program analyzes the deformation of the design cantilever structure profile. The planning of this long-span cantilever structure is designed with reference to SNI 1727:2020 on minimum design load and related criteria for buildings and other structures, and SNI 1729:2020 on specifications for structural steel buildings. The result of the planning obtained is the dimensions of the beam bar profile needed. Pratt truss long-span structure is able for used as a cantilever long-span structure. This is seen from the results of calculations using computer programs where the pratt truss model has a deformation/deflection structure that occurs not exceeding the specified limit, and the results of the profile design used safely in receiving loads, although the results of calculation analysis there are the most critical rod elements in withstanding the load of the axial force of the press, namely the t1 and b2 rods. While the most critical rods in withstanding the load of axial force pull are the rods d1 and a1.English translation.
