A hybrid is used, combining feature-based method transformed-based features with image-based grey level co-occurrence matrix features. When it comes to classifying cerebral hemorrhages CT images, the combined feature-based strategy performs better than the image-feature-based and transformed feature-based techniques. Natural language processing using deep learning techniques, particularly long short-term memory (LSTM), has become the go-to choice in applications like sentiment analysis and text analysis. This work presents a completely automated deep learning system for the purpose of classifying radiological data in order to diagnose intracranial hemorrhage (ICH). Long short-term memory (LSTM) units, a logistic function, and 1D convolution neural networks (CNN) make up the suggested automated deep learning architecture. These components were all trained and evaluated using a large dataset of 12,852 head computed tomography (CT) radiological reports.

The response of structure under shock is very important. For sandwich structures, the foam of other material with good energy absorbing capacity is an effective way to enhance the ability to resist external shock. In this work, numerical shock analysis is conducted for double-layered plate with foamed aluminum. The deformation process is firstly studied in case of initial shock velocity of 8.9m/s, then comparative analysis is conducted on the influence of different shock velocity on structural response.

This paper deals with the evaluations of lower and upper bounds of dynamic responses and natural frequencies for structures with uncertain interval parameters. The structural physical parameters, geometric dimensions and initial conditions can be considered as interval parameters. The modified Chebyshev interval method (MCIM) is presented to handle the uncertainties. In comparison with the Chebyshev interval method (CIM), MICM provides with tighter bounds of the time responses and natural frequencies without a significant increase in computation time. Monte Carlo method is also used to provide with exact bounds. MICM, CIM and Monte Carlo method are applied for structures with interval parameters, and the efficiency and accuracy of CIM and MCIM are verified.

The purpose of this study is to demonstrate the suitability and efficacy of the adjoint method on the aerodynamic shape optimization on a simple symmetrical airfoil NACA0018 at low Reynolds number for wind turbine application. The adjoint method has been used in many pressure-based numerical simulations with various degrees of success leading to optimized geometries in their respective uses. ANSYS Fluent code was used in this simulation. Lift to drag ratio was defined as the observables for which adjoint sensitivities were formulated. The objective function of the optimization was set to maximize the lift to drag ratio of the airfoil by 20%. The optimization regime showed significant increase in lift and drag ratio from the initial baseline NACA0018 value of 0.0211 up to 3.66 for the optimal NACAOpt. The results demonstrate the potential of the adjoint solver paired together with the gradient-based optimizer to improve the geometry for shape optimization in many CFD applications.

2205 duplex stainless steel suffers poor hot workability, especially whe1981hot-deformed. This investigation aims to determine the strain rate’s effect on the material’s dynamic recrystallization after heat treatment. Secondly, to ascertain the critical strain at which the recrystallization occurs. The as-rolled material was subjected to heat treatment at 1340 °C for some time. After heat treatment, the yielded equiaxed austenite morphology was used for this investigation. Gleeble 1500™ thermo-mechanical was used as a simulant in uniaxial compression mode. The deformation temperature was set at 850 °C, with maximum strain at 0.8 and carried out at 0.001 s-1, 0.01 s-1, 0.1 s-1, 1 s-1, 5 s-1 strain rates. The microstructure of before and after heat-treatment was evaluated using a light microscope, while the critical factors (stress and strain) were determined through the stress-strain curve. It was observed that the lowest strain rate generated the maximum critical stress and critical strain at 191.99 MPa and 0.08283, respectively. However, at the highest strain rate, the maximum critical stress and critical strain experienced by the material were at 336.32 MPa and 0.17577. Overall, it was established that the applied stain rate influenced the critical strain and stress of the material. It can be concluded that dynamic recrystallization can occur at any strain rate, but the applied stress determines the extent of the phenomenon.

Numerous publications on the transport of pollutants in a fixed bed, in particular in the treatment of waters still use two-parameter models: a capacity parameter measuring the delay of the breakthrough curve (CP) and a transfer kinetics parameter to translate the dispersion observed (Thomas model and Yoon-Nelson model), The authors totally neglect the role of the hydrodynamic dispersion which however largely contributes to the spread of the curves and thus the adjustments made on the analyzed breakthrough curves are invalid, Using three examples involving fixed beds of homogeneous adsorbent beads or sand, one of Lin et al [2013] with biochar-alginate grains (diameter 2.0 mm), the following from Jang et al. [2018] with resin beads (diameter 0.8 mm), and the last of our own work with a clay-limestone quartz sand of mean diameter 0.4 mm (Benaouag et al., 2018) we analyzed the validity of these models, For this we used as reference model a model with 4 parameters (Mixers in Cascade with Exchange) taking into account hydrodynamic dispersion, linear sharing and first-order mass transfer kinetics.
许多关于污染物在固定河床中运移的出版物，特别是关于水处理的出版物仍然使用双参数模型:在此基础上，作者完全忽略了水动力弥散的作用，而水动力弥散在很大程度上促进了曲线的扩散，因此对所分析的突破曲线所做的调整是无效的。林等[2013]之一biochar-alginate谷物(直径2.0毫米),以下从张成泽等。[2018]与树脂珠(直径0.8毫米),最后我们自己的工作clay-limestone石英砂的平均直径0.4毫米(Benaouag et al ., 2018)我们分析这些模型的有效性,为这个我们用四参数模型作为参考模型(搅拌机在级联交易所)考虑水动力弥散,线性共享和一阶传质动力学。

Each element of the exhaust system has a different function. The element that has the greatest impact on reducing the noise associated with exhaust gas discharge is the final silencer. The design of the final silencerr has a significant impact on vehicle noise. The paper presents the study of the impact of modifications of the final silencer with a construction other than the factory one on the noise emission level of the vehicle. The tests were carried out in accordance with the Polish standard PN-92/S-04051 regarding the permissible level of external noise of vehicles.

The environmental performance of emerging bio-based technologies must be assessed at an early stage of their development, when the process can still be modified for sustainable optimization, i.e. including environmental, social and economic aspects. The Life Cycle Analysis (LCA) methodology is already recognized as an effective solution for environmental analysis. However, the data obtained at the laboratory scale are incomplete in the initial stage of the eco-design of a new synthesis route, which complicates the inventory of the life cycle. Coupling a process modelling/simulation tool with LCA has proven to be an effective solution for providing inventory data. The simulation of a process is based on the selection of models allowing the environmental, energy and economic optimization of a technology to be developed on the production scale. The choice of models for the reaction and separation steps will certainly have a significant impact on the results of the environmental assessment. This article is dedicated to the study of the impact of the degree of complexity of the modelling of the reaction pathway on the environmental assessment of the process of methanolysis of urea to produce dimethyl carbonate (DMC).

This case study aims toward the importance of the application of rapid prototyping and tooling technology in die design and manufacturing. Many conventional machining processes of die manufacturing, including computer numeric control (CNC) machining and electric discharge machining (EDM), are used by the local manufacturers of die, but these processes are time-consuming and expensive. There is a need to explore opportunities to reduce die manufacturing costs. This paper aims to assist the development of low-cost dies through the application of rapid prototyping and tooling technology. For this purpose, solid works software was used to design the die of a 4-hole Lego Block. 3D printing was incorporated in the existing capability of investment casting process for die manufacturing. A proper gating system design consideration was taken into account to ensure the accurate flow of casting material for achieving fine surface finish. From the results, it has been observed that gating system design with four ingates gives the optimum value of surface finish (~3.4156μm). The proposed rapid prototyping and tooling technology makes the practitioners (tool makers) capable of making dies with complex shapes, superior surface finishes, and dimensional accuracy in less or no time.
