A Survey Of The Current State Of The Practice In Bridging The Gap Between Engineering Ontologies And Modeling Profiles For Engineering Applications, John Artus
Open Access Theses & Dissertations
Model-Based Systems Engineering holds the promise of enhancing systems engineering tasks and product quality through better, more efficient exchange of data across tools, personnel, and departments, a higher quality of analysis resulting from greater access to cross-discipline data, better coordination between engineering activities and those of program management, and many other benefits. Yet, there is still no standardized method for achieving commonality of architecture vocabulary across projects, across, companies, across industries such that entities operating in the same domain produce products that speak the same technical language. Some specialized domains, such as the Department of Defense (DoD), have developed Architecture …
Weather Prediction: Improving Accuracy Using Data Mining And Forecasting Techniques, Pedro Marquez
Weather Prediction: Improving Accuracy Using Data Mining And Forecasting Techniques, Pedro Marquez
Open Access Theses & Dissertations
This study is focused to provide the insights of weather to understand the significance of weather changes in any parameter. Weather forecasting contributes to the social and economic welfare in many sections of the society. Weather is extremely difficult to predict because it is a complex and chaotic system. This means that small errors in the initial conditions of a forecast grow rapidly and affect predictability. Nowadays, massive real-time data is being generated by IoT devices, radars, weather stations, and satellites. The need to adopt big data analytics in IoT applications is compelling. These two technologies have already been recognized …
Mathematical Modeling, Optimal Control And Stability Analysis For Dynamic Supply Chains, Yasser Alberto Davizon
Mathematical Modeling, Optimal Control And Stability Analysis For Dynamic Supply Chains, Yasser Alberto Davizon
Open Access Theses & Dissertations
Dynamic supply chains (SC) are important to reduce inventory, to enable the flow of materials, and maximize profits. By this, dynamic SC require proper decision-making with effective performance and synchronization. In operations and production planning processes, decision-makers develop convenient and suitable decisions, to validate their hypoThesis about which decisions incorporate more profit while reducing costs on enterprise operations. Based on this, inventory management plays a crucial point in the supply chain analysis. In general, SC processes raw material, cash, and information flows, taking into account the demand profile of the system. This research work presents the mathematical modeling, optimal control, …
Design Of Experiments Analysis Of Powder Removal Methods For Ebm Manufactured Ti-6al-4v Parts, Luis Cesar Ramos Castañeda
Design Of Experiments Analysis Of Powder Removal Methods For Ebm Manufactured Ti-6al-4v Parts, Luis Cesar Ramos Castañeda
Open Access Theses & Dissertations
Additive Manufacturing is a technology that allows the on-demand manufacturing of complex geometries that cannot be fabricated through traditional subtractive manufacturing methods. Powder Bed Fusion is one of the seven categories of Additive Manufacturing with two subcategories, the Laser Beam Melting and the Electron Beam Melting. Freedom of design, rapid prototyping, and customization are some of the benefits that this technology provides. Like any technology, there are limitations for each category and subcategory. The Electron Beam Melting uses the electron beam to pre-heat the powder bed, reducing the temperature difference between the build part and powder bed, causing the surrounding …
