The present study probed the creation of heat energy and concentrating into Newtonian liquids across vertical 3D-heated plates. The role of the Soret and Dufour theories in concentrating and energy formulas is discussed. The role of hybrid nanoparticles is introduced to illustrate particle efficiency in terms of solute and thermal energy. It is removed a viscous dissipation process and a changing magnetic field. The proposed approach is motivated by the need to maximize solute and thermal energy uses in biological and industrial domains. The constructed system of (partial differential equations) PDEs includes concentration, momentum, and thermal energy equations within various thermal characteristics. Transformations are used to formulate the system of (ordinary differential equations) ODEs for solution. To assess various features vs various variables, a Galerkin finite element approach is used. Motion into nanoscale components is shown to be smaller than motion into hybrid nanoparticles. Furthermore, fluctuations in heat energy and solute particle counts are seen in relation to changes in Soret, Eckert, magnetic, and Dufour numbers. The basic finding is that the generation of thermal energy for hybridized nanomaterials is much higher.

Revista Brasileira de Ortopedia 2020年第6期55卷 771-777页

作者： Dobke, Lothar Schmechel Bonadiman, João Artur Lopes, Osmar Valadão Saggin, Paulo Renato Israel, Charles Leonardo Spinelli, Leandro De Freitas Knee Surgery Service Instituto de Ortopedia e Traumatologia (IOT) Hospital São Vicente de Paulo (HSVP) Universidade Federal da Fronteira sul (UFFS) Passo Fundo RS Brazil Orthopedics and Traumatology Service Santa Casa de Misericórdia de Porto Alegre Rs Universidade de Passo Fundo RS Brazil Department of Mechanical Engineering Universidade de Passo Fundo Passo Fundo RS Brazil Graduate Program in Design and Manufacturing Processes Universidade de Passo Fundo Passo Fundo RS Brazil Department of Surgical Clinic Universidade Federal de Ciências da Saúde de Porto Alegre Porto Alegre RS Brazil

Objective: To evaluate different femoral fixation devices for medial patellofemoral ligament reconstruction and compare their effectiveness regarding fixation strength up to failure in porcine knees. Methods: Thirty porcine knees were used, divided into three groups of 10 knees. The removed grafts were dissected from the extensor tendons of porcine feet. In each group, the graft was fixed to the femur with an interference screw, an anchor, or adductor tenodesis. The three methods were subjected to biomechanical tests using a universal Tensile testing machine at a speed of 20 mm/minute. Results: The highest average linear resistance under lateral traction occurred in group 1, screw fixation (185.45 ± 41.22 N), followed by group 2, anchor fixation (152.97 ± 49, 43 N);the lower average was observed in group 3, tenodesis fixation (76.69 ± 18.90 N). According to the fixed error margin (5%), there was a significant difference between groups (p < 0.001);in addition, multiple comparison tests (between group pairs) also showed significant differences. Variability was small, since the variance coefficient was lower than 33.3%. Conclusion: Interference screws in bone tunnels and mountable anchors fixation with high resistance wire are strong enough for femoral fixation in porcine medial patellofemoral ligament reconstruction. Adductor tenodesis, however, was deemed fragile for such purpose. © 2020 Georg Thieme Verlag. All rights reserved.

The realization of novel technological opportunities given by computational and autonomous materials design requires efficient and effective frameworks. For more than two decades, aflow++ (Automatic-Flow Framework for Materials Discovery) has provided an interconnected collection of algorithms and workflows to address this challenge. This article contains an overview of the software and some of its most heavily-used functionalities, including algorithmic details, standards, and examples. Key thrusts are highlighted: the calculation of structural, electronic, thermodynamic, and thermomechanical properties in addition to the modeling of complex materials, such as high-entropy ceramics and bulk metallic glasses. The aflow++ software prioritizes interoperability, minimizing the number of independent parameters and tolerances. It ensures consistency of results across property sets — facilitating machine learning studies. The software also features various validation schemes, offering real-time quality assurance for data generated in a high-throughput fashion. Altogether, these considerations contribute to the development of large and reliable materials databases that can ultimately deliver future materials systems. © 2022, CC BY.

The aim of the present work is to provide better attentiveness to the industry management and to facilitate the implementation of manufacturing sustainability. A generic model aspect presents and investigates the correlation for descriptive survey validation of manufacturing sustainability. Which intends to investigate the correlation among benefits, drivers, barriers and triple bottom-lines. The results can provide executive awareness of the current complex relations and to the development of an implementation plan. Thereby it is possible to upgrade the level of a supply supply chain management, production, environmental efficiency and ground work. Furthermore it can lead to strengthen government policy as well as to the development of new manufacturing.

This research is about the analysis and design of variable-wheelbase bike. Aiming to the existing folding bike of all kinds, we collect patent communiqué and record information to classify the documents and give analysis of its merit and defect. We find the way of innovative design from the generalizing information. Finally, we choose multiple-linkage mechanism system to change the positions of seat, handle bar and rear wheel, which can also alter the riding position and control ability of user. In order to lower the cost, we reduce the numbers of linkages. This linkages system must be one freedom . Therefore, this research is proceeding the mechanical sustainable synthesizing with this design iuput, and develops a multiple-linkages mechanism system with 8 bares, 10 joints with one freedom to be the construction of bike frame. Then, we synthesizing the dimensions of bike frame by SolidWorks,and stimulating sporting motion and interference by the 3D CAD model, later, evaluate whether the 3D dummy meets the requirements or not. It will also make the CAE to proceed the stress analysis of the bike frame construction with ANSYS11. 0 to make sure the strength and security. Finally, may be we would make a prototype.

Exploring the limits to sustainable energy consumption for organisms and devices

引用

International Journal of Sustainable manufacturing 2008年第1-2期1卷 78-99页

作者： Reap, John Bras, Bert Sustainable Design and Manufacturing Program Systems Realisation Laboratory George W. Woodruff School of Mechanical Engineering Atlanta GA 30332-0405 United States

Energy consumption accounts for a significant portion of a product's environmental impacts. Biological research suggests the existence of a fundamental energetic limit. After reviewing research into the influence of thermodynamic and economic principles on living systems' evolution, a biological principle explaining the existence of a mass-specific energy consumption rate limit for living systems is identified and quantified. These findings lead to a potential sustainable engineering principle and metric. Simple assessments of consumer goods and vehicles illustrate the principle's application. Discussions of this biologically inspired limit and the general value of seeking environmental design guidance from living systems close this paper. Copyright © 2008 Inderscience Enterprises Ltd.

IIE Annual Conference and Expo 2008

作者： Gupta, Saraj Baird, Jenna Okudan, Gül E.

At the conceptual design stage, only few computational tools exist that aid designers to generate quality designs. The proposed methodology aims at generating robust computerized conceptual designs by incorporating Modularity, design for Assembly (DFA) and design for Variety (DFV) principles at the conceptual stage. Resulting conceptual design offers highest ease of assembly, and is composed of modules such that future changes in customer needs are easily satisfied by replacing minimum modules. This research paper illustrates the working methodology with the help of a case study example involving the design of a mounting system for holding a variable message sign (VMS).
