Conference paper (peer-reviewed)abstract
- A 3-D Frequency Selective Surface (FSS) with band-stop characteristics for X-band and Ku-band is proposed. A 3-D FSS unit cell is constructed by analyzing two 2-D FSS's. The size of the 3-D FSS unit cell is 5 mm × 5 mm wherein two layers of FR4 substrate with respective widths of 0.762 mm and 0.5 mm are used. Dual stop bands are obtained with this FSS unit cell around 10 GHz and 17.4 GHz; where a wide stop-band of 5.2 GHz is obtained. The parametric study carried out on the proposed design in terms change in nature of substrate, alternate use of different substrates and variation in angle of incidence. The 3-D FSS shows its band rejection property X-band and Ku-band respectively. Ansoft HFSS commercial EM solver software is used to carry out the simulation work.

A First Step Towards a Tool for Extending Ontologies
- 2021
-
In: Proceedings of the Sixth International Workshop on the Visualization and Interaction for Ontologies and Linked Data. - : CEUR Workshop proceedings. ; , s. 1-12
-
Conference paper (peer-reviewed)abstract
- Ontologies have been proposed as a means towards making data FAIR (Findable, Accessible, Interoperable, Reusable). This has attracted much interest in several communities and ontologies are being developed. However, to obtain good results when using ontologies in semantically-enabled applications, the ontologies need to be of high quality. One of the quality aspects is that the ontologies should be as complete as possible. In this paper we propose a first version of a tool that supports users in extending ontologies using a phrase-based approach. To demonstrate the usefulness of our proposed tool, we exemplify the use by extending the Materials Design Ontology.

Results of the Ontology Alignment Evaluation Initiative 2021
- 2021
-
In: Proceedings of the 16th International Workshop on Ontology Matching co-located with the 20th International Semantic Web Conference (ISWC 2021), Virtual conference, October 25, 2021. - : CEUR-WS.org. ; , s. 62-108, s. 62-108
-
Conference paper (peer-reviewed)abstract
- The Ontology Alignment Evaluation Initiative (OAEI) aims at comparing ontology matching systems on precisely defined test cases. These test cases can be based on ontologies of different levels of complexity and use different evaluation modalities (e.g., blind evaluation, open evaluation, or consensus).The OAEI 2021 campaign offered 13 tracks and was attended by 21 participants.This paper is an overall presentation of that campaign.

Factors affecting global supply chain design
- 2012
-
Conference paper (peer-reviewed)abstract
- Due to the limited existing knowledge pertaining to the factors which govern localization of operations and capabilities in a global supply chain, the purpose of the paper is to find out which factors and how they jointly affect the design of global supply chains. The relevant literature is reviewed and a concept matrix is developed. Five companies were selected in order to illustrate the issues of global supply chain design. Among them, three companies are considered to have efficient supply chain and less complex products, while the two others are considered to have responsive supply chain and more complex products. The issues discussed with the selected companies cover global sourcing, challenges, technological advancement and issues related to management control. The study identifies about fifty factors that affect global supply chain design, and specifically how theses relate to design decisions on location of factories and production, supplier selection and development, distribution of products and organisation of interfaces along the supply chain. The discrepancies between theory and practice as well as the implications for further research are discussed.

Factors affecting shifts in global supply chain networks : A configurational approach
- 2013
-
In: Proceedings of the 20th International Annual EurOMA conference, Dublin, Ireland, 9-12 June 2013, 2013.
-
Conference paper (peer-reviewed)abstract
- In certain situations, global companies strive to take advantage of short-term changes in economic and exchange rates on the never-ending journey of competitiveness. This paper seeks to extend Ferdows’s (2008) production network models by adding the factors affecting shifts between rooted and footloose network configurations. Two companies were selected in order to illustrate the models and reveal other possible factors. The identified factors are differentiated in terms of configuration and coordination and merged in a matrix. The trends and implications on global supply chains are also discussed.

Global supply chain design : Building a decision model
- 2012
-
Conference paper (peer-reviewed)abstract
- The knowledge pertaining to the factors, which govern localization of operations and capabilities in a global supply chain, is limited. The purpose of the paper is to find out which factors and how they jointly affect the design of a global supply chain. The relevant literature is reviewed and a concept matrix is developed. The study identifies 30 factors that affect a global supply chain design and specifically how theses relate to the design decisions on location of factories and production, supplier selection and development, distribution logistics, organisation of interfaces/enterprise information infrastructure along the supply chain and human resource development. The decision model is developed and the description of the model is done with the help of an example (location of a factory) by using the Analytical Hierarchy Process (AHP) (Saaty, 1990).

Sustainability reporting as a way to foster entrepreneurial universities
- 2018

Conference paper (peer-reviewed)abstract
- Higher education institutions (HEIs) play a major role in the development of societies. In the last decades, there has been an increasing interest on the commercialisation of knowledge by universities for economic development that lead to the emergence of the term “Entrepreneurial University”. This study aims to report the sustainability efforts of the University of Gävle, Sweden by applying a systematic tool, Graphical Assessment of Sustainability in Universities (GASU). This study highlights sustainability reporting as a way to improve communication practices between universities and stakeholder. The systematic and holistic assessment of HEIs gives insights of collaboration opportunities and by that foster their entrepreneurial journey.
