Over past few decades, research on authentic materials has been focused on helping teachers provide their learners� teaching materials. Most of the researches in this area explore the benefits and drawbacks of authentic materials utilization in the classroom. This multiple case study aims at investigating benefits of and barriers in using authentic materials presented as a digital media used in their EFL classrooms. Document and an interview were employed to reveal the teachers� perception. The findings indicate although it was considered difficult to find and organize, digitized authentic materials helped teachers in teaching English as a Foreign Language for learners with various levels and backgrounds. Its use could help teachers motivate and promote their students� interest in learning. However, disselection and misuse of it might not meet students� needs and interest in learning. Good teachers� capacity in finding and using the digitized authentic materials could encourage better learning process and students� better learning achievement. Therefore, it is recommended that for the further study, learners� perception also need to be explored.

A Print-on-Demand (POD) System was developed to expand the availability of printed extension and educational materials. The layouts are developed on a computer using text files and digital images. Images can be edited with graphics programs before insertion into the layouts. The completed materials are stored, in final format, on disk and are printed on an as-needed basis or distributed over computer networks. The system greatly reduces the production time to a finished product and gives great flexibility in revising publications. The basic POD system consists of a computer, a mass storage device, and a printer. Photo CDs and video capture are the most common sources of digital images. Photo CDs produce higher-quality images but require more time to get the digitized images due to commercial processing. For Photo CDs, the images are photographed with a 35-mm camera and sent for processing and digitizing. With live video capture, a video camera is connected directly to a computer and images are digitized in real time. Tape recorded images also can be used, but the image quality is less than live video. Video images are digitized at 72 pixels per inch (ppi), and Photo CD images are available at >3000 ppi. Video images are best digitized at twice their desired size and reduced to final size when increasing the resolution.

Annotation:

In this article, a digitized stress function-based feed rate scheduling algorithm is formulated for the prevention of tool breakage while having an optimum material removal rate in mesoscale rough milling of hardened steel. Instead of setting limits to the cutting forces and material removal rates, the presented method regulates the tool’s stresses. A 3D coupled Eulerian-Lagrangian finite element method (FEM) model is used to simulate a 3D chip flow-based stress according to the mesoscale tool’s rotation during cutting of hardened steel. Maximum uncut chip thickness and tool engaging angle of the uncut chip is identified as the fundamental driving factors of tool breakage in down milling configuration. Furthermore, a multiple linear regression model is formed to digitize the stress with two major factors for digitized feed scheduling. The optimum feed rates for each segment along the tool path can be obtained through finite element models and a multiple linear regression model. The feed rate scheduling method is validated through cutting experiments with tool paths of linear and arc segments. In a series of experimental validations, the algorithm demonstrated the capability of reducing the machining time while eliminating cutting tool breakages.

A segmented neutron detection system based on windowless silicon-PIN photodiodes has been designed and tested with various hydrogen rich converter materials. Each channel from the segmented structure uses an independent custom-made low noise charge sensitive preamplifier and an OPAMP based shaping amplifier. Signals from each channel were digitized using a fast, single bit digitizer and the pulses from each channel were simultaneously recorded with an FPGA board. An AmBe neutron source was used for the test measurements and relative neutron detection efficiencies were determined. This low-cost detector can be used for monitoring fast neutrons in reactors, accelerator facilities or medical centers using neutron therapy.

Digitized Mandarin paediatric speech perception tests are limited in Malaysia for measuring outcomes among children fitted with amplification devices. Mandarin speech perception tests from other countries may not be suitable to be used in Malaysia due to regional vocabulary differences. This study aimed to develop digitized test materials to test Mandarin-speaking preschool children in Malaysia. This is a two-phased cross-sectional study where Mandarin words (n=113) were gathered with test item pictures developed and tested on 40 Mandarin-speaking children (aged 2;0 to 5;11 years old) with normal hearing in Study I. A total of 80 of 113 words with high familiarity among children were selected in Study I. In Study II, digital recordings of the words was conducted, followed by acoustic analysis, and sound quality evaluation. In total, 94 out of the 480 recorded word tokens were excluded in acoustic analysis. The remaining 386 tokens received good quality rating by three professionals. Validation of the recorded word tokens and pictures to select the final test items involved 20 Mandarin-speaking young adults in Study II. A total of 160 tokens were selected as final items and all pictures corresponding to these test items were validated as suitable representation of the test items. In conclusion, digitally recorded stimuli and pictures have been developed for a Mandarin speech perception test appropriate for Mandarin-speaking pre-school children in Malaysia. Ongoing research includes collecting normative data for the test and future research involves evaluating the test application in local audiology clinics.

Options for acquiring digital images are explored. Photo CDs, scanned images, and video capture are the most common sources of images. Photo CDs produce the highest-quality images, but require more time to get the digitized images due to commercial processing. For Photo CDs, the images are photographed with a 35-mm camera and sent for processing and digitizing. Slide and flat bed scanning is time consuming when working with bulk quantities of images. With live video capture, a video camera is directly connected to a computer and images are digitized in real time. Tape-recorded images can be also be used, but the image quality is less than live video. VWeb server allows rapid dissemination of the materials. This procedure greatly reduces the production time to a finished product, gives flexibility in revising publications and allows a greater variety of materials to be produced.

Generalized analysis of 427 Russian dissertation researches in the specialty 14.03.10 (14.00.46) «Clinical Laboratory Diagnostics» over the period of 2000-2013 is presented. Currently complete author’s abstracts can be remotely accessed at official sites of institutions with Thesis Boards (since 2007) and at the site of State Commission for Academic Degrees and Titles, Ministry of Education and Science of the Russian Federation (for Doctoral theses – since 2007, for Candidate’s theses – since April 2012). Thesis materials for the year 2013 don’t full in libraries, so the collection of 407 theses for the period of 2000–2012 was used for comparison. In thesis e-library of the Russian State Library 238 theses are digitized, or 55.2% of works total collection in the field of clinical laboratory diagnostics, in e-library of the Russian National Library – 331 author’s abstracts or 81.5 %. The digitized theses materials can be accessed free of charge in libraries reading halls, remote access can be provided for a fee. To optimize information support to scientific research there is a necessity to create in Russia a common theses database at Research Electronic Library, to organize a national subscription to digitized theses materials, and to coordinate the fields of documents scanning. Digitized theses database allows remote access, as well for foreign users. For integration into the world research community one should provide English abstract of the thesis (max. 250–300 characters) on the last page of the author’s abstract.

In the Fourth Industrial Revolution, artificial intelligence technology and big data science are emerging rapidly. To apply these informational technologies to the engineering industries, it is essential to digitize the data that are currently archived in image or hard-copy format. For previously created design drawings, the consistency between the design products is reduced in the digitization process, and the accuracy and reliability of estimates of the equipment and materials by the digitized drawings are remarkably low. In this paper, we propose a method and system of automatically recognizing and extracting design information from imaged piping and instrumentation diagram (P&ID) drawings and automatically generating digitized drawings based on the extracted data by using digital image processing techniques such as template matching and sliding window method. First, the symbols are recognized by template matching and extracted from the imaged P&ID drawing and registered automatically in the database. Then, lines and text are recognized and extracted from in the imaged P&ID drawing using the sliding window method and aspect ratio calculation, respectively. The extracted symbols for equipment and lines are associated with the attributes of the closest text and are stored in the database in neutral format. It is mapped with the predefined intelligent P&ID information and transformed to commercial P&ID tool formats with the associated information stored. As illustrated through the validation case studies, the intelligent digitized drawings generated by the above automatic conversion system, the consistency of the design product is maintained, and the problems experienced with the traditional and manual P&ID input method by engineering companies, such as time consumption, missing items, and misspellings, are solved through the final fine-tune validation process.

In order to initiate a taxonomical revision of the Dianthus sylvestris group, an inventory of historical herbarium materials from ZA and ZAHO collections was conducted. Herbarium specimens of D. sylvestris group from these two herbaria were digitized and the data from the original herbarium labels were inserted in the Flora Croatica Database. A total of 344 herbarium sheets were digitized and six taxa (D. sylvestris Wulfen in Jacq. ssp. sylvestris, D. sylvestris ssp. tergestinus (Rchb.) Hayek, D. sylvestris ssp. longicaulis (Ten.) Greuter et Burdet, D. sylvestris ssp. nodosus (Tausch) Hayek, D. siculus C. Presl and D. arrosti C. Presl) were registered within studied collections. Inventory of herbarium sheets from ZA and ZAHO historical collections provided a significant insight into historical distributional data of D. sylvestris taxa related to the area of the Balkan Peninsula, which is a prerequisite for accurate taxonomic/ geographic sampling for further morphological and molecular analyses.

In this experiment, the method of phase spectral analysis was used to monitor ultrasonic moduli changes in a two part epoxy adhesive bonded between steel adherends during cure as well as during cyclic loading. Ultrasonic signals were generated using a piezoelectric transducer operated in the pulse-echo mode. These signals were digitized using a high-speed transient digitizer (100 MHz sampling rate) and stored for post-test analysis in the memory of a minicomputer. Based on this information, ultrasonic attenuation and phase velocity measurements (as a function of frequency) were obtained for both longitudinal and shear waves throughout the cure cycle. This technique was also used to monitor the cure of adhesives with different mix ratios in order to evaluate the utility of this approach for quality control purposes. The potential use of the method to study fatigue damage development was also considered.

Purpose Technological supports provide multimodal presentation of text, which may increase understandability of written materials by people with aphasia (PWA). Extant literature reveals that digitized natural speech and synthetic computer-generated speech within these supports are comprehensible by PWA at discrete time points; however, understandability following repeated exposure is unexplored. This pilot study evaluated understanding of, and preference regarding, synthetic and digitized natural speech during and following repeated exposures by PWA. Method This multiple–case-study project included four adults with aphasia. Participants independently completed various listening tasks in a single digitized natural speech condition and one of two synthetic speech conditions across a 2-week period. Participants completed sessions to evaluate maintenance effects and generalization to novel stimuli and an untrained synthetic voice condition 1 week and 1 month following daily practice. Results Study participants demonstrated understandability evident by at- or near-ceiling performance during baseline, practice, and follow-up sessions in the digitized natural condition and one synthetic speech condition. Individuals with mild aphasia achieved relatively consistent performance during independent practice, whereas performance of individuals with moderate aphasia fluctuated in both conditions. All four participants demonstrated variable understanding during generalization and maintenance tasks at follow-up time points. Participants most frequently indicated preference for digitized natural speech over either synthetic speech condition. Conclusions Findings hold important clinical implications when considering feasibility of utilizing these speech forms as compensatory strategies for PWA. Further research is needed to more fully understand the effects of repeated exposure to synthetic speech on comprehension among PWA.

ABSTRACT Since 2010, the author has been part of the Central State Hospital (CSH) Digital Library and Archives Project to digitize records from the first state psychiatric hospital for African Americans, founded in 1870 in Virginia at the pleadings of the Freedman's Bureau and run by the state since then.1 Many of the records of this hospital not yet accessioned by the Library of Virginia have now been digitized, and this project is working on a set of tools for lawful access, including one that can be used for automated redaction to protect sensitive data while responding to the needs of different stakeholder groups. Project participants were especially concerned about understanding the communities that have grown up around state-run psychiatric hospitals, as the project was done at the request of the hospital. The proposed plan is to work with the Central State Hospital and the Library of Virginia to provide the project materials to both. The records that were chosen to be digitized included the minutes of the people who first ran the hospital as well as the registers kept on the patients, which differ over time.2 In the past ten to fifteen years, professional discussion about community archives has responded to communities' desires to build their own archives so that they can be treated fairly, especially with reference to records created about them and kept by others, including records found in state archives.

Abstract Digital libraries have been strategic in preserving and making non-movable cultural heritage information accessible to everyone with network connections. In light of their cultural and historical importance in the ancient “Silk Road,” murals and stone caves in Dunhuang, a remote city in northwest China,have been digitized, and the first batch of digitized visual materials has been made available to the general public through the e-Dunhuang digital library since May 2016. The aim of this study was to systematically evaluate e-Dunhuang from users’ perspectives, through usability testing with nine user tasks in different complexity levels and in-depth interviews with regard to a set of criteria in user experience. The results of quantitative analysis confirmed the overall effectiveness of e-Dunhuang in supporting user task completion and demonstrated significant improvements in several criteria over an earlier panorama collection of Dunhuang caves. The results of qualitative analysis revealed in-depth reasons for why participants felt satisfied with some criteria but had concerns with other criteria. Based on the findings, suggestions are proposed for further improvement in e-Dunhuang. As e-Dunhuang is a representative repository of digitized visual materials of cultural heritage, this study offers insights and empirical findings on user-centered evaluation of cultural heritage digital libraries.

Purpose This paper aims to teach educators a variety of ways to navigate the digital collections of the Library of Congress, which include primary source materials from the past which can be used to instruct students of all grade levels from elementary through college. Design/methodology/approach Workshops for preservice teachers, practicing teachers and their college-level and librarian counterparts focused on advanced searching skills and pedagogical structures which help students access primary sources and use them as evidence to draw conclusions about historical events in history. Findings Many of the Library of Congress’ holdings have been digitized, described and categorized for ease of access (subject, keyword and metadata descriptors) and for ease of rights management (copyright, ownership and permissions indicated for each digital object). Practical implications Digitized primary sources help students create deeper understandings of historical events and periods and allow for multiple perspectives on the same events, thus teaching students valuable skills in drawing conclusions based on primary and secondary information sources. Originality/value Online collections from the Library of Congress are free for use by teachers, students and the general public, and the Library of Congress Teaching with Primary Sources program makes available free training for teachers in how to use the materials, as well as provides lesson plans, project ideas and thematic units for use in K-12 schools and beyond.

The article discusses some aspects of the organization of the information system of the Archive of the First President of the Republic of Uzbekistan Islam Karimov. The problem of digitalization of archival activities is quite relevant for Uzbekistan due to the fact that traditional approaches to the construction of information retrieval mechanisms and the organization of information services in archiving today often do not correspond to the required level of efficiency and user needs. As part of the work carried out, the specific task was to organize a software environment for the formation of an electronic catalog of archived descriptions, filling databases of digitized copies of archival materials, as well as flexible multidimensional search and presentation of information. The way to solve this problem is to use the archival information system «AtoM». As a result, a database of digitized archival materials was created, reflecting the life and work of the First President of the Republic of Uzbekistan Islam Karimov, equipped with a developed search and reference apparatus.

In the last few years we have begun developing a database for studying the history of American Sign Language (ASL), and more generally as a prototype for making historical and contemporary sign language materials accessible to a variety of users. Our prototype began with a set of films, produced by the National Association of the Deaf, of master signers from the period 1910 to 1920. In addition to a digitized frame by frame version of these films, we have added a full transcription and a linguistic coding of each sign and sentence in the films.

In the last few years we have begun developing a database for studying the history of American Sign Language (ASL), and more generally as a prototype for making historical and contemporary sign language materials accessible to a variety of users. Our prototype began with a set of films, produced by the National Association of the Deaf, of master signers from the period 1910 to 1920. In addition to a digitized frame by frame version of these films, we have added a full transcription and a linguistic coding of each sign and sentence in the films. We are in the process of expanding these materials, adding further types of coding and representation of the items, and developing an interface permitting users to access parts of these materials in accord with their interests and needs. This paper describes our work thus far, and illustrates one possible use of these materials with an example of historical linguistic change.

The development of new technologies and the information society has accelerated changes in everyday life and modern teaching. Information and communication technologies (ICT) better motivate students to learn. In order to better preserve historical sources, they are digitized and thus protected, hence researchers can access the source faster and at a less cost. The possibilities of using the Internet in teaching are vast. It is necessary for schools to have computers, as well as for teachers and students to be motivated to use new electronic sources. Many websites have original historical material, from written and printed sources to audio-visual ones. We can call all this material digital resources (materials, sources, electronic historical sources). Teachers need to create engaging and imaginative teaching materials. However, a critical approach and caution in working with materials from the internet is essential. It is the teacher's responsibility to recommend verified sites and documents. Much of the material on the Internet has been posted with the conscious intention of spreading inaccurate data. The possibilities of ICT are great in history studies, as well. It is possible to modernize teaching at all levels of studies, but the financial capabilities of schools do not allow the possibility of keeping up with those innovations. One of the web portals that can be used for teaching purposes with its digitized content is Europeana. It is a database of the cultural and historical heritage of Europe, through which it is possible to search the digitized material of institutions. The Europeana portal is a broad project that provides free access to tens of millions of digital units. One of the most important collections within this portal is dedicated to the First World War and is called Europeana 1914-1918.

Aim. To compare digital images of conventional radiographs with the original radiographs for perceived clarity of periapical lesions and the quality of root canal treatment. Materials and Methods. One hundred and four intraoral periapical radiographs of patients with endodontically treated teeth were randomly selected. The radiographs were digitized using an MD300 USB X-ray Reader. The digital images were transferred to an HP laptop. Three evaluators compared each conventional radiograph with the matching digital image. The images were ranked for clarity and assessed for diagnostic quality; data were analyzed using the Reliability Calculation “ReCal.” Results. Both the digital images and conventional films had comparable clarity and diagnostic quality. Results indicated a moderate agreement between the evaluators. Conclusions. Conventional radiographs digitized using an MD300 USB X-ray Reader have similar clarity and diagnostic quality in comparison to the original radiographs.

Materials that were born digital, and printed materials that have been digitized, have aided an updated examination of nineteenth-century US whaling voyages’ financial returns. Items included the American Offshore Whaling Voyages dataset from whalinghistory.org , The Whalemen’s Shipping List and Merchant’s Transcript, a congressman’s speech and a state’s census reports. These works and others, with analysis, showed that for the 11,257 analysable voyages ending in the 1800s, the mean return was 4.7% and 4.6% for whaling and US government bonds, respectively. Ideally, this work will place the nineteenth-century US whaling industry returns in context of other investments.

Current issues of digitization of newspapers' collections are in the focus of this topic. There is discussed sharing of responsibilities on digitization of newspapers, selection of criteria and digitization priorities. Particularly, the determination of the scanning method (in the library or outsourced) and the solutions for the best representation of newspapers: as artifacts or as information set, are of great importance. There is provided the detailed analysis of the activities of federal and regional libraries, newspapers publishers and commercial information centers, dealing with digitization of the national printed newspapers. The emphasis was made to the problems of practical protection of copyright and intellectual property in digitization of the periodicals and in the usage of these materials by institutions, including libraries.

The article analyses publication of a large set of historical and archival documents on the history of the Second World War and the Great Patriotic War on the website of the Boris Yeltsin Presidential Library. Since 2009 it functions as the national electronic repository of digital copies of the most important documents on the history of Russian statehood and Russian language, as well as multimedia, multifunctional, cultural, scientific, educational and information-analytical centre with the status of the national library of Russia. In the “Collections” section, the libraryʼs website places online publications of various forms and subjects. The author considers the methods of publishing digitized copies of archival documents. Within the frames of the first part of the Internet project “The Second World War in archival documents (set of digitized archival documents, footage and photo materials)” there are published 1767 electronic copies of documents, then promised to continue. There is placed the full list of published documents, it provides the ability to sort them, search by date and place of storage. Virtual multimedia exhibition “The Great Patriotic War, which determined the outcome of the Second World War. For the 75th anniversary of the victory in the Great Patriotic War of 1941—1945” presents more than 500 official documents, documentary photographs, periodical materials and leaflets. The authors of the exhibition apparently consider the online publication “Combat actions of the air defence forces of the navy in the Great Patriotic War of 1941—1945” as a kind of rare publication, therefore they decided to publish the facsimile reproduction of it. The article concludes on the great significance of the project “The Second World War in archival documents (set of digitized archival documents, footage and photo materials)” that placed a large set of documents from Federal and departmental archives, many of which were first declassified. The author reveals shortcomings of Internet publications of archival documents in the field of placement methods related to inaccurate determination of their readership.

Digitized beam-forming metal reflectarray antennas are designed for the millimeter-wave region. The phase control of antennas has been implemented by the reconfiguration of rectangular grooves on a metal plate. The antenna has 1147 elements arranged in an aluminum metal plate. The depths of all metal grooves are manipulated for designed phase control of high-gain beam-aimed reflectors. We have demonstrated a digitized reconfigurable metal reflectarray to steer a re-radiated millimeter-wave field from the reflector in a two-dimensional scanning plane from −20∘ to 20∘. The far-field patterns show that the measured gain of the 2-bit reflectarray is only 1 dB lower than that of a non-digitized reflectarray antenna. The measured peak gain is higher than 31.7 dB, and the measurements show that the gain of the full 40∘ scanned beam is 31.7 dB and well-defined scanned beams are obtained with a maximum scan gain loss of 0.2 dB. The proposed reconfigurable antennas can be a useful candidate for high-gain beam-aimed antennas for practical reflecting surfaces and a variety of wireless and satellite communication systems.

ABSTRACT Objective: To determine the accuracy (trueness and precision) of two different rapid prototyping (RP) techniques for the physical reproduction of three-dimensional (3D) digital orthodontic study casts, a comparative assessment using two 3D STL files of two different maxillary dentitions (two cases) as a reference was accomplished. Materials and Methods: Five RP replicas per case were fabricated using both stereolithography (SLA) and the PolyJet system. The 20 reproduced casts were digitized with a highly accurate reference scanner, and surface superimpositions were performed. Precision was measured by superimposing the digitized replicas within each case with themselves. Superimposing the digitized replicas with the corresponding STL reference files assessed trueness. Statistical significance between the two tested RP procedures was evaluated with independent-sample t-tests (P < .05). Results: The SLA and PolyJet replicas showed statistically significant differences for trueness and precision. The precision of both tested RP systems was high, with mean deviations in stereolithographic models of 23 (±6) μm and in PolyJet replicas of 46 (±13) μm. The mean deviation for trueness in stereolithographic replicas was 109 (±4) μm, while in PolyJet replicas, it was 66 (±14) μm. Conclusions: Comparing the STL reference files, the PolyJet replicas showed higher trueness than the SLA models. But the precision measurements favored the SLA technique. The dimensional errors observed in this study were a maximum of 127 μm. In the present study, both types of reproduced digital orthodontic models are suitable for diagnostics and treatment planning.

When we talk about digitization processes, it is necessary to understand that they can be done in countless different ways, qualities and techniques, from cell phones to high resolution captures or more complex systems such as multispectral and threedimensional digitization. These differences have an impact on the amount and detail of information captured by each technique, the human and material resources necessary for each technique, maintenance, and long-term care for the digital surrogates generated. The desire for digitizing cultural heritage materials must be linked to programs for the preservation of the materials being digitized and the preservation of all the digital files generated by digitization. The institution needs to find the balance between the resulting quality and quantity of the materials that will be digitized and what is possible to sustain in the long term through these processes. When we want the great, this can be the enemy of the good. The good can be done in the best way and be great. It is also possible to work with projects ranging from good to great according to decisions and selections made by the institution on how to deal with digital preservation, digitization, access and preservation in the long term. We want the best for our institutions and collections, and we aim for efficient dissemination programs using the materials generated by digitization. The purpose of this text is to help us think about our wishes for digitization and dissemination within this universe of possibilities.
