CNN-based Feature Extraction for Robotic Laser Scanning of Weld Grooves in Tubular T-joints
(Chapter, 2022)This paper presents an algorithm for feature point extraction from scanning data of large tubular T-joints (a subtype of a TKY joint). Extracting such feature points is a vital step for robot path generation in robotic ... -
Collaborative Fault Diagnosis Decision Fusion Algorithm Based on Improved DS Evidence Theory
(Chapter, 2020)DS evidence theory has in obtaining a correct diagnosis when confronted with highly conflicting evidence, a collaborative fault diagnosis decision fusion algorithm based on an improved version of DS evidence theory is ... -
Combined Safety and Security Risk Analysis using the UFoI-E method: A Case Study of an Autonomous Surface vessel
(Chapter, 2019)Many standards consider safety and security risk analysis as separate fields, specifying the system specific safety or security issues and methods to analyze them. Having these separated fields of safety and security ... -
Common cause failures and cascading failures in technical systems: Similarities, differences and barriers
(Chapter, 2018)Many technical systems continue to increase in size and complexity, with more interactions and interdependencies between components. Dependent failures, such as common cause failures and cascading failures, are becoming ... -
A Comparison of Hazardous Scenarios in Architectures with Different Integration Types
(Chapter, 2020)Whether or not to allow some integration between process control and safety systems has been an ongoing debate amongst safety researchers and practitioners. The principle of keeping it simple and the principle of having ... -
Component-Based Modeling and Simulation of Nonlinear Drill-String Dynamics
(Chapter, 2019)In this paper, we present a dynamic model for a generic drill-string. The model is developed with the intention for component-based simulation with coupling to external subsystems. The performance of the drill-string is ... -
A Concept of Information-Based Strategy for Accident Prevention
(Chapter, 2023) -
Condition-based Maintenance for Systems with Dependencies: Related Concepts, Challenges and Opportunities
(Chapter, 2021)Many critical systems with dependencies do not collapse immediately due to single-point failures but are more vulnerable to the cascading effects of these failures. Condition-based maintenance (CBM) has been found useful ... -
Configuration and Control of KMR iiwa Mobile Robots using ROS2
(Chapter, 2020)In this paper, we present a novel system for controlling a KMR iiwa mobile robot using ROS2. The KMR iiwa is a mobile robot with a manipulator mounted on the base that is developed by the robot manufacturer KUKA. The ... -
Control Model for Intelligent and Demand-Driven Supply Chains
(Chapter, 2011)Orchestrating supply chains is challenging. This chapter describes how to control a supply chain to make it truly demand-driven – based on the assumption that all relevant information is made available to all partners in ... -
Controller and observer design for first order LTI systems with unknown dynamics
(Chapter, 2018)The design of controllers and observers often relies on first order models of the system in question. These models are often obtained either through step-response tests, through on-line or off-line identification, or through ... -
Crane load position control using Lyapunov-based pendulum damping and nonlinear MPC position control
(Chapter, 2019)A crane control system is presented where the crane load can track a position trajectory with ultimately bounded pendulum motions of the load. This is done with an inner loop using a Lyapunov-based damping controller which ... -
Design Considerations for a Directed Energy Deposition Cell
(Chapter, 2023)Setting up a robotised additive manufacturing machine requires attention to several safety aspects, including integration of different systems, a functional work area, human-machine interfaces and convenience in operation. ... -
Design for environment with aluminium extrusions
(Chapter, 1998)Extruded aluminium sections have many features that make them suitable for use in environment-friendly products. Still there are much to be done to reduce the variability of section properties and to optimize the processing ... -
Determination of constraint forces for an offshore crane on a moving base
(Chapter, 2018)In this paper we propose an efficient method for calculating the forces of constraints in an open-chain multibody system, like a robot mounted on a vehicle with 6 degrees of freedom. The dynamical model is based on Kane's ... -
Developing a training and educational programme for learning energy-efficient building renovation
(Chapter, 2022)The building construction industry has a significant potential to develop and apply energy efficient solutions, and hence contribute to address climate and environmental concerns. Energy efficient solutions are applied not ... -
Development of a wearable system to capture team (n> 2) interactions in engineering design teams
(Chapter, 2016)This paper presents the development and ideas behind a comprehensive system prototype of wearable Radiofrequency transceivers, which, by sending small radio packets between devices, are acting as a proxy for dynamically ... -
Digital Assembly Assistance System in Industry 4.0 Era: A Case Study with Projected Augmented Reality
(Chapter, 2021)Automation has increased more and more in manufacturing companies over the last decades. However, manual labor is still used in a variety of complex tasks and is currently irreplaceable, especially in assembly operations. ... -
