Open-source digital technologies for low-cost monitoring of historical constructions

This paper shows new possibilities of using novel, open-source, low-cost platforms for the structural health monitoring of heritage structures. The objective of the study is to present an assessment of increasingly available open-source digital modeling and fabrication technologies in order to identify the suitable counterparts of the typical components of a continuous static monitoring system for a historical construction. The results of the research include a simple case-study, which is presented with low-cost, open-source, calibrated components, as well as an assessment of different alternatives for deploying basic structural health monitoring arrangements. The results of the research show the great potential of these existing technologies that may help to promote a widespread and cost-efficient monitoring of the built cultural heritage. Such scenario may contribute to the onset of commonplace digital records of historical constructions in an open-source, versatile and reliable fashion.Peer ReviewedPostprint (author's final draft

Visions and Challenges in Managing and Preserving Data to Measure Quality of Life

Health-related data analysis plays an important role in self-knowledge, disease prevention, diagnosis, and quality of life assessment. With the advent of data-driven solutions, a myriad of apps and Internet of Things (IoT) devices (wearables, home-medical sensors, etc) facilitates data collection and provide cloud storage with a central administration. More recently, blockchain and other distributed ledgers became available as alternative storage options based on decentralised organisation systems. We bring attention to the human data bleeding problem and argue that neither centralised nor decentralised system organisations are a magic bullet for data-driven innovation if individual, community and societal values are ignored. The motivation for this position paper is to elaborate on strategies to protect privacy as well as to encourage data sharing and support open data without requiring a complex access protocol for researchers. Our main contribution is to outline the design of a self-regulated Open Health Archive (OHA) system with focus on quality of life (QoL) data.Comment: DSS 2018: Data-Driven Self-Regulating System

Molecular access to multi-dimensionally encoded information

Polymer scientist have only recently realized that information storage on the molecular level is not only restricted to DNA-based systems. Similar encoding and decoding of data have been demonstrated on synthetic polymers that could overcome some of the drawbacks associated with DNA, such as the ability to make use of a larger monomer alphabet. This feature article describes some of the recent data storage strategies that were investigated, ranging from writing information on linear sequence-defined macromolecules up to layer-by-layer casted surfaces and QR codes. In addition, some strategies to increase storage density are elaborated and some trends regarding future perspectives on molecular data storage from the literature are critically evaluated. This work ends with highlighting the demand for new strategies setting up reliable solutions for future data management technologies

The Ohio State University Libraries Audiovisual Assessment Interim Report

The 26-month audiovisual (AV) assessment took place from June 2017 to August 2019 with a focus on rare or unique audiovisual items. Curators and archivists within each unit identified collections or collecting areas for significance or research value. Approximately 65% of AV materials in seven library units has not been assessed. Upon completion, 18,389 audiovisual items in 32 distinct formats were individually assessed

Economics and Engineering for Preserving Digital Content

Progress towards practical long-term preservation seems to be stalled. Preservationists cannot afford specially developed technology, but must exploit what is created for the marketplace. Economic and technical facts suggest that most preservation ork should be shifted from repository institutions to information producers and consumers. Prior publications describe solutions for all known conceptual challenges of preserving a single digital object, but do not deal with software development or scaling to large collections. Much of the document handling software needed is available. It has, however, not yet been selected, adapted, integrated, or deployed for digital preservation. The daily tools of both information producers and information consumers can be extended to embed preservation packaging without much burdening these users. We describe a practical strategy for detailed design and implementation. Document handling is intrinsically complicated because of human sensitivity to communication nuances. Our engineering section therefore starts by discussing how project managers can master the many pertinent details.

Audit and Certification of Digital Repositories: Creating a Mandate for the Digital Curation Centre (DCC)

The article examines the issues surrounding the audit and certification of digital repositories in light of the work that the RLG/NARA Task Force did to draw up guidelines and the need for these guidelines to be validated.

Economic evaluation of LIFE methodology

Background: The LIFE project (Lifecycle Information For E-Literature) was carried out during 2004-2006 by a consortium consisting of The British Library and University College London Library Services . The project was joint venture funded by JISC under the programme area Institutional Management Support and Collaboration. The project has received favourable feedback, for instance during a workshop organised at the end of it, and JISC has agreed to fund a second phase during 2007-2008. The consortium has been strengthened by three associate partners (SHERPA-LEAP Consortium, SHERPA-DP and the Medical Research Council). In addition some funds were reserved for the use of an outside economic consultant for an evaluation of the life-cycle models that emerged as the key results from the first phase. The LIFE-2 project consists of five work packages, and this report is part of the first of these. The objective of WP 1 is formulated in the LIFE 2 Project proposal as follows: Validation of the economic modelling and methodology for the Lifecycle and Generic Preservation formulae developed in Phase 1 of the LIFE project, with technical and presentational development of the models. Cloudlake Consulting Oy has been commissioned by the consortium to carry out this validation. The report has been written by Bo-Christer Björk. He is professor of Information Systems Science at the Swedish School of Economics and Business Administration in Helsinki, Finland. He has been conducting research concerning the scientific publishing process since 2000 and has published several peer reviewed journal articles as well as conference papers on the subject. He is often an invited speaker at international workshops in this area
