  • Preparation of biobased composites using novel thermoset polymers from soybean oil and a natural fibre reinforcement
  • 2009
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Health related issues, stringent environmental protection policies, search for cost effective and alternative materials, crave for renewability and sustainability and quest for high performance materials for structural applications give the motivation for research in polymer composites and material science. Due to the health, safety and environmental concerns over the conventional synthetic materials and the legislation against their usage both in domestic and industrial applications, alternatives sources that will be comparable in properties are being sought. There is an emerging market for biodegradable polymers which is expected to increase substantially in the coming years.[1] Preparation of Composites Airlaid and woven flax fibre mats were first treated with 4% sodium hydroxide solution for one hour and then washed with plenty of water. This was done in order to remove any residual impurities. The fibres were dried at room temperature for 24 hr and then dried in a vacuum oven for 1hr at a temperature of 105°С. The 8 sheets of the fibre were hand laid cross- wisely and the impregnation was done manually. The fibre/ resin ratio was about 60% to 40%. Methacrylated soybean oil, methacrylic anhydride and acetic anhydride modified soybean oil were the synthesized matrices used. The compression moulding was done at a temperature of 170°С for 5 min at 40bar. Characterisations The tensile testing was performed based on an ISO-test method for tensile tests on plastic materials. The Charpy impact strength of unnotched specimens was evaluated in accordance with ISO 179 using a Zwick test instrument and scanning electron microscopy analysis was done on the fractured specimens. The composites showed various mechanical properties, having impact strengths between 24 and 63 kJ/m² and tensile strength up to 51MPa.

  • Computer-aided Morphology Expansion for Old Swedish
  • 2014
  • Ingår i: Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC'14) May 26-31, 2014 Reykjavik, Iceland. - 9782951740884 ; , s. 1102-1105
  • Konferensbidrag (refereegranskat)abstract
    • In this paper we describe and evaluate a tool for paradigm induction and lexicon extraction that has been applied to Old Swedish. The tool is semi-supervised and uses a small seed lexicon and unannotated corpora to derive full inflection tables for input lemmata. In the work presented here, the tool has been modified to deal with the rich spelling variation found in Old Swedish texts. We also present some initial experiments, which are the first steps towards creating a large-scale morphology for Old Swedish.

  • Exploring collaboration among historically black universities and doctoral/research universities in the USA
  • 2003
  • Konferensbidrag (refereegranskat)abstract
    • In the USA, historically black colleges and universities (HBCUs) seldom have sufficient resources and infrastructure to support faculty and student research or doctoral education. In contrast, doctoral/research universities (DRUs) have extensive resources and infrastructure to support research and doctoral education. istoricHBoth HBCUs and DRUs have talented faculty and students, and collaboration between faculty and students and HBCUs and DRUs has the potential of increasing the physical and intellectual resources brought to bear in research and student education. However, not all collaborations are successful. We studied four instances of collaboration among HBCUs and DRUs to investigate points of tension, identify successful practices, and gather suggestions for improving existing and future collaborations between institutions with different cultural heritages and organizational priorities.

  • IDA : från projekt till levande verksamhet
  • 2009
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Vuxenstuderande är en viktig målgrupp för folkbiblioteken och biblioteken en betydelsefull resurs för målgruppen. Att etablera ett fungerade samarbete med vuxenutbildningen borde vara självklart. På vilket sätt är inte lika självklart. Hur vi kan bygga upp en sådan ömsesidig relation ser förstås olika ut beroende på förutsättningarna och idéerna hos biblioteken och vilka utbildningar och andra samarbetspartners som finns på orten. Verksamhet riktad till vuxenstuderande är ständigt i förändring. IDA verksamheten i Malmö Stad har förändrats, från projekt till levande verksamhet. Från traditionell biblioteksservice till behovsanpassad service. För att möta våra besökares behov kommer den fortsätta att vara i förändring.

  • Blockchain-Based Framework for Traceability – A Case Example of Nonwoven Supply Chain
  • 2019
  • Ingår i: EDANA-Nonwovens Innovation Academy 2019.
  • Konferensbidrag (refereegranskat)abstract
    • Supply chain traceability has emerged as a prime requirement for multi-tier supply chains. It not only enables the supply chain visibility but also caters to the consumer requirements related to transparency, quality assurance, and production tracking. Nonwoven supply chain is one such example that particularly requires traceability implementation due to prevailing problems related to information asymmetry and complex supply chain networks. Conversely, it is challenging for supply chain partners to share all the competitive information in the unsecure environment. In this context, in line with Industry 4.0, this study investigates blockchain technology, which uses a shared and secured data infrastructure to keep track of information about assets and requires no central authority to function. It further proposes a blockchain-based traceability framework that explains supply chain partner interaction and network architecture at organizational level and smart contract and transaction validation rules at the operational level. In order to illustrate the application of the framework, the study presents an example of a nonwoven supply chain to track the nonwoven manufacturing and distribution processes. The proposed system can build a technology-based trust among the supply chain actors, where the distributed ledger would be used to store and authenticate of supply chain transactions.
