This study aims to find the maximum, usable, feed limit at different arc-energies and use the findings in multi-pass welding planning for robotic welding, taking into consideration the high controllability of robot movements. A combined studies using numerical analyses and practical experiments to calculate the feed limits for different arc energies. Each weld where analysed both mathematical, ...

Nowadays, many manufacturing companies need to face competition both in domestic and international level. Due to this circumstance, manufacturers recognize that one useful method to enhance their competence is reducing the lead-time of manufacturing. There are many researchers focused on minimize the time of actual cutting, tool path optimization and energy consumption optimization etc. However, few ...

In the modern business world, the trend that calls for a harmonious coexistence between economic development and the natural environment is growing ever stronger. Under such global context, the sustainability of a company has become more and more emphasized. As a crucial part of the supply chain management, the outsourcing process should as well be able to deal with such concerns under the guidance ...

A complete, structural and comprehensive description of indoor localization technology is pre-sented in this paper. It concluded the basic techniques for distance measurement in indoor locali-zation, the basic localize principles, the topologies and algorithms which are often used in indoor localization area. Then how to perform indoor localization with sensors which are available in modern smartphones ...

Our world is continuously developing by new generation of engineers, artists, politicians, travelers and this list can be continued. They will research, improve and design new reality for the future. One of our missions is to help them by bringing better understanding of existing technologies. This is the goal of my thesis: to create an experimental loop to demonstrate pigging activity in the ...

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 ...

Designing for downhole environment is a challenging process. High pressure and temperature are the main well conditions that effect the design decisions and the tool geometry. Also, the well fluids can obtain high concentration of corrosive content such H2S acid that plays major role in material selection. The intention of this study is to develop Downhole Control Valve that can be connected to ...

This thesis is a part of the Master of Science degree in Industrial Engineering at the University of Tromsø – The arctic University of Norway, Campus Narvik. The aim of this thesis is to improve the logistic service and increase the competitiveness of ports in Northern Norway in order to attract more port users. A literature review on the topics of logistics in seaports is presented, along with an ...

This master thesis contains an overview of the additive manufacturing technology and building process of the large-scale Fused Deposition Modelling (FDM) additive manufacturing machine from the old Wafer Handling Diffusion machine. The thesis study is mainly focused on practical work and describes the techniques used during the project execution. The built machine can print large 3D prototypes from ...
