A comparative study on the dynamic response of three semisubmersible floating offshore wind turbines
2019
Abstract Currently, there is a great interest to globally develop offshore wind energy due to the greenhouse effect and energy crisis. Great efforts have been devoted to develop reliable floating offshore wind energy technology to exploit the wind energy resources in deep seas. This paper presents a comparative study of the dynamic response of three different semisubmersible floating wind turbine structures. All the three platforms support the same 5MW wind turbine. The platforms examined are: a V-shaped Semi, an OC4-DeepCwind Semi and a Braceless Semi at 200 m water depth. A dynamic analysis is carried out in order to calculate and compare the performance of these platforms. The comparison…
Foundations of offshore wind turbines: A review
2019
Abstract Offshore wind is a source of clean, renewable energy of great potential value to the power industry in the context of a low carbon society. Rapid development of offshore wind energy depends on a good understanding of technical issues related to offshore wind turbines, which is spurring ongoing research and development programmes. Foundations of offshore wind turbines present one of the main challenges in offshore wind turbine design. This paper reviews the present state of knowledge concerning geotechnical and structural issues affecting foundation types under consideration for the support structures of offshore wind turbines, and provides recommendations for future research and de…
Ecological Invitation to Engage with Public Displays
2018
Interactive public displays pose several research issues, which include display blindness and interaction blindness. In this paper, we shortly introduce our idea of a sound-based system to overcome the display blindness, and some experiments that we are carrying out in order to test its effectiveness.
Maintaining dignity in vulnerability: A qualitative study of the residents' perspective on dignity in nursing homes
2016
Postprint tilgjengelig 20.03.17. Background Older people, living in nursing homes, are exposed to diverse situations, which may be associated with loss of dignity. To help them maintain their dignity, it is important to explore, how dignity is preserved in such context. Views of dignity and factors influencing dignity have been studied from both the residents’ and the care providers’ perspective. However, most of these studies pertain to experiences in the dying or the illness context. Knowledge is scarce about how older people experience their dignity within their everyday lives in nursing homes. Aim To illuminate the meaning of maintaining dignity from the perspective of older people livi…
Enterprise architecture operationalization and institutional pluralism: The case of the Norwegian Hospital sector
2021
Enterprise architecture (EA) is a systematic way of designing, planning, and implementing process and technology changes to address the complexity of information system (IS) landscapes. EA is operationalized when architecture visions move towards realization through concrete projects. We report a case study on the dynamics of operationalizing EA in the Norwegian hospital sector by exploring different EA project trajectories. Our empirical context is an institutionally pluralistic setting where multiple logics coexist. We show that the distinct logic of EA is added to the institutional context and we find that tensions among existing medical, technical, and managerial logics and EA principle…
A novel abstraction for swarm intelligence: particle field optimization
2016
Particle swarm optimization (PSO) is a popular meta-heuristic for black-box optimization. In essence, within this paradigm, the system is fully defined by a swarm of "particles" each characterized by a set of features such as its position, velocity and acceleration. The consequent optimized global best solution is obtained by comparing the personal best solutions of the entire swarm. Many variations and extensions of PSO have been developed since its creation in 1995, and the algorithm remains a popular topic of research. In this work we submit a new, abstracted perspective of the PSO system, where we attempt to move away from the swarm of individual particles, but rather characterize each …
Influence of Ad Congruence and Social Cues on the Probability of Choosing a Restaurant
2020
Abstract. Information processing of digital content includes conscious and un-conscious processes, memory, attitudes, and emotions and moods. Build up into the Heuristic‐Systematic Model, that states that persuasion can occur through a systematic or heuristic way, this research explores the effect of social media (SM) ratings and the ad content embedded in the SM website. Online ratings (part of the user-generated content (UGC) in SM platforms) are often heuristics cues. Subtle forms of congruence, such as the matching category between a restaurant advertiser and the third-party ad, as well as UGC, could have an impact on con-sumers’ attitudes towards the former. However, research on …
Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method
2007
Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…

Enterprise Architecture management challenges in the Norwegian health sector
2017
Abstract Enterprise Architecture (EA) is instrumental to align ICT and business strategy, and many organizations carry out substantial efforts to implement EA. It is therefore seen as imperative to drive the digital strategy, identifying innovative new business models and technologies, and realizing more business value of technology investments. However, recent work suggest that it is a challenging task to implement enterprise architecture in an organization. This study explores the implementation of enterprise architecture (EA) in the Norwegian health sector. We found a number of challenges that impeded the process toward a common EA: unclear enterprise architecture roles, ineffective comm…
