Digitarium is a joint initiative of the Finnish Museum of Natural History and the University of Eastern Finland. It was established in 2010 as a dedicated shop for the large-scale digitisation of natural history collections. Digitarium offers service packages based on the digitisation process, including tagging, imaging, data entry, georeferencing, filtering, and validation. During the process, all specimens are imaged, and distance workers take care of the data entry from the images. The customer receives the data in Darwin Core Archive format, as well as images of the specimens and their labels. Digitarium also offers the option of publishing images through Morphbank, sharing data through GBIF, and archiving data for long-term storage. Service packages can also be designed on demand to respond to the specific needs of the customer. The paper also discusses logistics, costs, and intellectual property rights (IPR) issues related to the work that Digitarium undertakes.

By the end of 2009 the Dutch Government awarded the establishment of NCB Naturalis with €30M funding. The amount is invested in three programs: Scientific Infrastructure for DNA Barcoding, Integration and Relocation of collections and Collection Digitisation. In this article we describe the highlights of the Digitisation Programme.

Digitisation programmes in many institutes frequently involve disparate and irregular funding, diverse selection criteria and scope, with different members of staff managing and operating the processes. These factors have influenced the decision at the Royal Botanic Garden Edinburgh to develop an integrated workflow for the digitisation of herbarium specimens which is modular and scalable to enable a single overall workflow to be used for all digitisation projects. This integrated workflow is comprised of three principal elements: a specimen workflow, a data workflow and an image workflow.

At the Royal Botanic Garden Edinburgh (RBGE) the use of Optical Character Recognition (OCR) to aid the digitisation process has been investigated. This was tested using a herbarium specimen digitisation process with two stages of data entry. Records were initially batch-processed to add data extracted from the OCR text prior to being sorted based on Collector and/or Country. Using images of the specimens, a team of six digitisers then added data to the specimen records. To investigate whether the data from OCR aid the digitisation process, they completed a series of trials which compared the efficiency of data entry between sorted and unsorted batches of specimens. A survey was carried out to explore the opinion of the digitisation staff to the different sorting options. In total 7,200 specimens were processed.

The Music Archive in the School of Music-Conservatorium at Monash University contains a diverse array of original and often unique sound, visual and bibliographic materials. A large percentage of the sound component represents decades of ethnomusicological field research and comprises reel-to-reel and cassette tapes, a growing number of which are slowly decaying. Some of our sound collections, which include cylinder recordings and 78 rpm records, have also been acquired as donations from a variety of organisations and interested members of the public. Preservation of such a valuable and extensive resource is therefore a top priority. Accordingly, we have successfully completed two digitisation projects (both ARC funded), and are currently undertaking a third in collaboration with Monash University’s ARROW (Australian Research Repositories Online to the World) team. In fact, collaboration has been a key factor in all three projects because it has facilitated the resolution of a number of issues associated with each particular stage – preparation, process and product – of digitisation. Some of those issues will be discussed in this paper and include observations about the criteria used to determine choice of material for digitisation; the manner of transporting the original media to and from a digitising service provider given the invaluable nature of the material; the metadata elements to describe the digitised sound files; storage of the digitised sound files and whether said storage is for preservation only with very limited access...

This report thoroughly investigates the available research on the benefits of repatriating cultural materials to Indigenous communities in Australia and abroad. Additionally, it presents significant real-life examples of repatriation and local heritage management projects. A number of suggestions are drawn from the research and examples in the form of research and policy recommendations. There is an international tendency that encourages collecting institutions to repatriate to Indigenous populations human remains, sacred/secret materials, and cultural materials. These materials have been collected either through unethical or illegal ways, but also through more benign ways such as consensual research. Today, many physical and digital repatriation projects are led by many collecting agencies, assisted in their efforts by different kinds of legislations. However, getting access to cultural materials is still difficult for many Aboriginal and Torres Strait Islander people. Collecting agencies as AIA TSIS are promoting projects that could facilitate this access. In this context, the project of a National Indigenous Knowledge Centre Network (NIKCN) is currently studied and is going to be submitted by the end of the year 2010 to the Government. This could be a key in the resolution of this issue and in the reconciliation process. AIA TSIS encourages the creation of this network jointly with its projects of digitisation of archives resources. Several examples of repatriation and local heritage management in Australia and other parts of the world are discussed here. These cases are used to show the benefits of such projects...

This paper presents the improvement of the spurious free dynamic range (SFDR) for digitisation using antenna arrays. Nonlinearities in the analogue-to-digital conversion degrade the overall SFDR of the digitisation process. We show that array processing, ie, the use of multiple sensors such as antennas or hydrophones with appropriate signal processing can improve the resulting SFDR at the beamform output. By taking advantage of spatial-temporal aliasing and the invisible regions, significant improvements can be obtained using linear, or more effectively, optimal beamforming.; Rice, F. White, L.B.

A novel spectrometer was developed and used to measure the cross section for the 16O(n,alpha) reaction at IRMM. The basic parts of the new instrument are an ionisation chamber, a gas oxygen target, and signal digitisation. It is shown that simultaneous digitisation of the anode and cathode signals allows an effective background suppression and the accurate determination of the number of reaction events and the number of atoms in the gas target. Cross section values for the 16O(n,alpha) reaction measured in the energy range 3.95-9.0MeV are presented. None of the existing nuclear data libraries describes well the IRMM data in the entire energy range.; JRC.D.5-Neutron physics

Digitisation techniques are being rapidly adopted to nuclear measurements due to large progress made in computing performance. Waveform digitisers are able to record the complete detector output signal with a high dynamic range. This method has obvious advantages compared to the traditional analogue technique, where separate electronic units are applied for selection and storage of the information: Full information contained in the output signal of a detector is recorded and makes possible to apply different signal processing algorithms during data analysis to focus on different aspects of the given experiment using the same data set repeatedly. The choice is limited only by the imagination of the experimentalist. It is also possible to increase the counting rate while maintaining successful particle discrimination still being able to fully determine the physical properties of events separated by a few hundreds of nanoseconds. The rapid increase in computer power and in data storage capacity stimulated the use of waveform digitizers as a new technique for nuclear experiments. The apparent advantages have been demonstrated in recent feasibility studies. It has been shown, that this technique improves the quality of particle identification...

This paper argue that the processes of digitisation and a user-based taste for interactivity have far-reaching implications for broadcast television. While much previous writing has focused on the ways in which digitisation impacts on broadcast television production, regulation, market demand, competition, and policy, this study is interested in the ways in which we can theorise the impact of interactivity on television viewers’ engagement with alternative forms of television distribution. It is argued that rigid television scheduling and the flow of television series as ‘slow release’ is increasingly less compatible with potential viewing patterns of everyday, western urban viewers, and that access to television series through DVD releases and Internet downloads results from an emerging cultural desire or demand by viewers for greater control over the temporal aspects of television entertainment.

Can we move beyond simply networking creative individuals to establishing diverse communities of practice for innovation through discursive methods. Furthermore, can we digitise their creativity activities within an integrative socio-cultural collaborative technology platform that could then support distributed innovation. First, we consider the complexity of creative cultures from the perspective of design innovation, including how to nurture creativity activities in what we call Creative Gardens. Specifically, how they could grow, diverge, and combine, be- ing cultivated to nurture emergent, disruptive, collaborative innovation. Then, we consider the digitisation of Creative Gardens from the perspective of digital culture. Specifically, the tenets of Creative Gardens as dynamic and innovative communities. This includes considering the challenges and opportunities around digitisation, the influences around the connectivity with knowledge cultivation, and the potential for distributed innovation as collective intelligence to utilise diverse expertise. We conclude be considering the importance of the issues and questions raised, and their potential for the future.; Comment: 4 pages, conference

Signal digitisation may produce significant effects in balloon - borne or space CMB experiments, since the limited bandwidth for downlink of data requires imposes a large quantisation step q applied on board by the instrument acquisition chain. In this paper we present a study of the impact of the quantization error in CMB experiments using, as a working case, simulated data from the Planck/LFI. At TOD level, the effect of the quantization can be approximated as a source of nearly normally distributed noise. At map level, the data quantization alters the noise distribution and the expectation of some higher order moments. Finally, at the levell of power spectra, the quantization introduces a power excess, that, although related to the instrument and mission parameters, is weakly dependent on the multipole l at middle and large l and can be quite accurately subtracted, leaving a residual uncertainty of few % of the RMS uncertainty. Only for l<30 the quantization removal is less accurate.; Comment: 15 pages, 5 figures, LaTeX2e, A&A style (aa.cls). Release 1, april 1st 2003. Submitted to A&A for the pubblication, april 1st 2003.

The investigation finds that digitisation-on-demand and print on-demand services have the potential to provide greater value access to libraries? collections and could help a library to realise its true potential as a ?long tail?. There are at present a number of practical and financial limitations that prevent this from being fully realised. Whilst the concept remains a viable one and demand is noted, copyright legislation restricts the material available for full digitisation to a niche subset of a library?s? whole collection. For digitisation-on-demand, start-up costs remain high, which itself endangers a higher level of risk if a self-funding service is not used. Lease hire models for equipment could help mitigate this. For print on demand, start-up costs are also relatively high. Third party solutions could provide an alternative. In both cases, users may object to additional costs.; This work was conducted as part of the Arcadia Programme, a three year programme funded by a grant from the Arcadia Fund.

This is the author accepted manuscript. The final version is available from IEEE via http://dx.doi.org/10.1109/ICCW.2015.7247197; Digital radio over fibre (RoF) technology has been suggested as a promising solution to replace conventional analogue RoF technology for multi-service in-building wireless coverage. However in conventional digital RoF, digitisation leads to high data rates which in turn results in high capital expenditure (CAPEX) and operational expenditure (OPEX). This paper investigates a novel methodology to transmit efficiently a digitised radio service over an optical link to provide wireless coverage. We demonstrate a digital processing technique that is able to compress the digitised 20MHz bandwidth Long Term Evolution (LTE) data stream to a much lower level than in a conventional link without impairing its radio performance.; This work is supported by Engineering and Physical Sciences Research Council (EPSRC) via the Digital Distributed Antenna System (DDAS) project and Beijing Institute of Aerospace Control Devices (BIACD), a subsidiary institute of China Academy of Aerospace Electronics Technology (CAAET) via the Smart In-building Wireless System using Flexible Transmission Technology (SWIFT) project.

This article, based on a presentation given at the UKSG annual conference in April 2008, is about the JISC large-scale digitisation programme, which started in 2004 when HEFCE gave JISC a one-off grant of £10 million. JISC handed the responsibility for this fund to its Content Services committee, of which I was a member at the time, and from there the Digitisation Advisory Group (DAG) was set up to manage the programme. I was asked to be chair and I have continued in that role despite having completed my term of office on the committee a couple of years ago.

This paper outlines South African History Online as a NGO that focuses on the enhancement of history especially at school level. The advent of digital and social media platforms has changed the way scholars learn and the way they perceive their world. The book, paper and journals should no longer provide the exclusive model for historical knowledge to be passed on. With this in mind, SAHO has developed a comprehensive online programme that focuses on the current curriculum as laid out by the Department of Education. The development of this website into an online classroom will assist both teachers and learners. Learners should be exposed to the wonders of digitisation and have the advantage of viewing primary source documents in their classrooms. This turns a normal classroom into a virtual archive making the learners instant historians who can now investigate their own case studies. Teachers have the opportunity of telling stories in new ways and in different means, and can use various materials from SAHO's online media and library section to give the learners the opportunity to relive the story. SAHO has various projects such as the development of the online curriculum material and aids for history from Grades 4 to 12. The aim is to build up this project into a comprehensive online encyclopaedia. An Arts and Culture classroom will soon be developed in a similar format. SAHO's teacher outreach programme...
