Abstract
Purpose
The purpose of the study is to evaluate the objectives, priorities and criteria of digitization. It also analyses the open access initiatives adopted by the special libraries in National Capital Region of India. The paper further examines the motivating factors of using digital resources.
Design/methodology/approach
The research paper is based on primary survey of librarians and users of special libraries. Weighted index has been used to analyse the factors of digitization while factor analysis is used to study the open access initiatives adopted by the libraries.
Findings
Based on the primary goal of libraries, i.e. to increase their global visibility and the ultimate purpose of such digital projects is to provide greater access to their collections to promote research activities. The paper summarizes that increased accessibility is the most preferred objective; content value is most preferred criterion for digitization. The paper further identifies factors that motivated users to use digital resources.
Practical implications
The availability of digital literature not only helps the local users but provides access to their resources and thus increases the visibility of these libraries globally. The revelation of special libraries to undertake such ventures is not only helpful to establish better information availability and visibility but also to maximize its value and worthiness.
Originality/value
Most existing studies remain on the level of collecting data and interpreting specific cases on digital conversion but this paper not only interprets the reasons of digitization but also investigates reasons of user needs by factorizing them. This paper examines the objectives, criteria and prioritization of material for digitization. It further identifies the factors motivating users to access these digital resources.

Abstract
This paper concerns with the measurement uncertainty estimation in the analog‐to‐digital conversion‐based instruments. By using an ad hoc developed software tool, the Monte Carlo method is applied in order to assess the uncertainties associated with the measurement results, overcoming the possible inapplicability of the pure theoretical approach prescribed in the ISO – “Guide to the Expression of Uncertainty in Measurement”. By implementing the software tool in the measurement instruments, the proposed approach can be utilized in order to make the instrument itself able to auto‐estimate the measurement uncertainties.

Abstract
Purpose
The digital down converter (DDC) is a principal component in modern communication systems. The DDC process traditionally entails quadrature down conversion, bandwidth reducing filters and commensurate sample rate reduction. To avoid group delay, distortion linear phase FIR filters are used in the DDC. The filter performance specifications related to deep stopband attenuation, small in-band ripple and narrow transition bandwidth lead to filters with a large number of coefficients. To reduce the computational workload of the filtering process, filtering is often performed as a two-stage process, the first stage being a down sampling Hoegenauer (or cascade-integrated comb) filter and a reduced sample rate FIR filter. An alternative option is an M-Path polyphase partition of a band cantered FIR filter. Even though IIR filters offer reduced workload to implement a specific filtering task, the authors avoid using them because of their poor group delay characteristics. This paper aims to propose the design of M-path, approximately linear phase IIR filters as an alternative option to the M-path FIR filter.
Design/methodology/approach
Two filter designs are presented in the paper. The first approach uses linear phase IIR low pass structure to reduce the filter’s coefficient. Whereas the second approach uses multipath polyphase structure to design approximately linear phase IIR filter in DDC.
Findings
The authors have compared the performance and workload of the proposed polyphase structured IIR filters with state-of-the-art filter design used in DDC. The proposed design is seen to satisfy tight design specification with a significant reduction in arithmetic operations and required power consumption.
Originality/value
The proposed design is an alternate solution to the M-path polyphase FIR filter offering very less number of coefficients in the filter design. Proposed DDC using polyphase structured IIR filter satisfies the requirement of linear phase with the least number of computation cost in comparison with other DDC structure.

Abstract
Purpose
The aim of the research was to create a site which could host an archive of moving image associated with the town of Fraserburgh in Scotland, but could also include other digital artefacts to support and enhance the narratives contained within the films. Elements of digital storytelling were utilised, and a purposely designed section, “behind the film”, was included within the site which saw stories presented and supported with the use of archive newspaper clippings, photography and a series of reflective audio clips recorded for the research.
Design/methodology/approach
“Fraserburgh on Film” is an online platform created for the purpose of collating digital heritage film from the communities situated in the corner of North East Scotland. The research adopted an ethnographic approach working within the community, with James Taylor and other contributors to collect and curate moving images associated with the town. Archival research then supplemented these films. A digital platform was then constructed, tested and launched as the archival repository for the materials collected.
Findings
The research highlights the importance of having a close association with the community in question and provides details about the creation of the platform and framing it in the context of a vehicle for digital storytelling and participatory heritage. The article demonstrates how archive film should be gathered, edited and remastered for long-term preservation and access. Practical aspects such as video hosting, searchability, metadata are explored as are subsequent methods of dissemination and engagement.
Practical implications
The research highlights a number of practical decisions which must be made when considering similar projects. These include gaining access to the moving images in the first place but also significant infrastructural issues around the creation, organisation and dissemination of an online digital repository. These lessons are transferable to other small community-based cultural and heritage organisations.
Social implications
The archive has been very positively received in the community as an important repository for preserving community heritage and identity. High levels of public engagement have been demonstrated since its launch, which has led to new material being discovered. The archive has a wider cultural legacy across the North East of Scotland because of both the nature of the films and the widespread use of the Doric dialect.
Originality/value
The originality lies in the distinctive amount of moving image (and oral history) collected by local historian, James Taylor and his willingness to allow his materials to be edited and repurposed to ensure their long-term survival. The lessons learnt in this project are transferable to other locations in terms of both collecting material, the creation of the hosting platform and in crowdsourcing background information. The crucial importance of working with community partners in digital heritage work is reinforced. The research affords practical illustrations of steps to be taken and factors to be considered. It demonstrates how a well-crafted digital heritage product can genuinely engage with the community.

Abstract
This paper deals with the uncertainty in digital measurement systems designed for power quality applications. The main goal of this work is to evaluate such uncertainty by means of a Monte Carlo method recently proposed in the literature. The accuracy of the measurement result obtained with a DSP‐based instrument for power quality metering depends on the behavior of the devices located in both the conditioning block and A/D conversion stage: it is thus necessary to consider the uncertainties introduced by each component of the system and the propagation of their effects through the measurement chain. Here, the uncertainty is estimated starting from the technical specifications provided by the manufacturers of these devices. Experimental results are reported to show the importance of some concerns about the practical implementation of the proposed methodology in a real instrument.

Abstract
Purpose
Project management techniques for digital initiatives must shift with the transformation of content from analog to digital, from singular projects to mass-digitization and large-scale digital preservation. How are project management methods employed across digital practices, from digitization, to online access, to preservation? How can project management methods evolve to create a collaborative workflow across collection and service areas of librarianship, centered on digital stewardship?
Methodology/approach
Solutions for these questions are illustrated in an explanation of the workflows implemented at the University of Maryland, College Park Libraries and reflected upon in a case study of a recent digital initiative.
Findings
Centered on the efforts of two departments in the Libraries’ Digital Systems and Stewardship division, this chapter outlines the origins, techniques, and integration of digital project management with a focus on Waterfall and Agile project management. Furthermore, the integration and transition of project management methodologies and tools between groups is emphasized, mirroring the transformation of analog media to digital formats and the requisite shifts in thinking such projects require.
Originality/value
These case studies are based on research across the profession and implementation at the University of Maryland, College Park Libraries. The local application of two established project management techniques, Waterfall and Agile, are summarized and compared. Though regularly employed in application development, applying Agile project management in libraries is a relatively new practice and has not been widely documented in library literature.

Structured Abstract
Purpose – To explicate how to design a digital internship that encourages both the teacher candidate and the K-12 student to participate in problem-based learning. Framed by the theories of academic motivation and new literacies, this chapter presents templates to demonstrate how a digital internship can be designed that results in the learning goals of both the students and the teacher candidates being met.
Design – Digital internships provide teacher candidates with the opportunity to teach K-12 students online, observe licensed teachers design and employ lessons, and analyze this pedagogical learning space, yet education preparation programs (EPPs) fail to harness this rich learning experience. This chapter makes a case for why EPPs benefit from participating in digital internships, how they can become involved, and results from this learning experience.
Findings – Findings from digital internship research studies indicate that despite frustrations, online mentoring opportunities give teacher candidates a chance to reflect on the work needed to create relationships necessary to instruct effectively. Through them, candidates can also develop dispositions of new literacies and bridge theory and practice in EPPs. Furthermore, digital internships may serve to empower teacher candidates and support them in being successful in teacher preparation coursework.
Practical Implications – Digital internships contribute to best practices in teaching digital literacies by providing examples of how EPPs can design curriculum that situates teacher candidates to observe pedagogy in online environments. These internships provide candidates the opportunity to mentor K-12 students in these spaces and provide teacher candidates time to process how they can best motivate students and give specific feedback to encourage learning. Furthermore, digital internships can include primary resources to enrich units of instruction across content areas and grade levels.
