This paper proposes a data processing scheme for laser spot thermography (LST) applied for nondestructive testing (NDT) of composite laminates. The LST involves recording multiple thermographic sequences, resulting in large amounts of data that have to be processed cumulatively to evaluate the diagnostic information. This paper demonstrates a new data processing scheme based on parameterization and ...

Traditionally, product deletion is a reactive decision driven by low sales volume and profit margin. However, the complexities involved in product management and consumer behavior volatilities make it necessary to account for a broad range of financial and non-financial factors. Besides, proactive product deletion may be required for a company to reduce the risk of draining resources, adjust to the ...

This paper presents a decision-support model aiming, primarily, at maximizing the productivity of surface coal mining activities through operational planning and management. The model is formulated based upon mixed integer programming, and it determines the optimal production plan of the shovels and allocation plan of the haul trucks in order to minimize operational cost, fuel consumption as well ...

Identifying flexible loads, such as a heat pump, has an essential role in a home energy management system. In this study, an adaptive ensemble filtering framework integrated with long short-term memory (LSTM) is proposed for identifying flexible loads. The proposed framework, called AEFLSTM, takes advantage of filtering techniques and the representational power of LSTM for load disaggregation by ...

The aim of this research is to assess the response of a thin membrane subjected to high-pressure gas loading for inflation. This procedure is applied during the design process of the membrane structure to allow the product to resist high-pressure loading and to further characterize the hyper-elastic material. The simulation in this work considers the standard procedures used in the LS-DYNA software, ...

This thesis explores the history, concept and criteria of flexible manufacturing systems. A small-scale test bench is designed and constructed for educational and demonstrational pur- poses. The test bench in comprised of an industrial robot, a CNC machine, and a conveyor. These are all controlled and automated from a PLC with a connected touch panel for human machine interface. It describes in ...

Oppgavens hensikt var å designe en kran som skulle være klar til produksjon når prosjektet ferdigstilles. Under prosjekteringen skulle alle aspekter av krandesignet undersøkes. Kranen skulle arktifiseres, dette vil si gjøres klar for en arktiskmaritim vinter. Alle komponenter ble designet med en minimum sikkerhetsfaktor på 1.33, dog har de aller fleste komponentene en høyere sikkerhetsfaktor. Den ...

Capacitive power transfer (CPT) is a near-field wireless power transfer (WPT) technology that has attracted attention in different charging applications. By utilizing electric fields, CPT gives charging systems advantages in terms of cost, weight, flexibility, and mobility. This paper surveys a number of empirical published works in a period between 2015 and 2023. Additionally, it discusses theoretical ...

In this thesis “Design of pipeline flexibility bench” an exertion has been made to make a conclusive study of fluid flow through pipe. Analysis has been carried out using analytical and numerical approach, where advance computer aided engineering tools such as CFD & FEM approach is used to study the flow behavior in different pipe configurations. Results show a significant change in wall shear stress ...

"This report describes phase I of the project ""Design of an expandable junk catcher"", which is carried out on behalf of Qinterra Technologies, Department of Plugs & Packers in Narvik, as a part of the subject SHO6263 Diploma thesis M-ID. The main purpose of the project is to develop a new type of well intervention equipment to solve the problem of unwanted residue from debris on temporary installed ...
