Full textAbstract:
This research is to evaluate the feasibility of applying three-dimensional modelling of the close-range photogrammetry in documenting archaeological monuments by using digital photogrammetry image processing software and digital consumer camera. The digital camera used was Nikon D3100, the processing software was (AgiSoft PhotoScan) and (ArcGIS, ArcScene extension). The study area was selected in the centre of Baghdad province by choosing one of the archeological monuments in it, namely the Abbasid alace. A set of camera locations represent the locations of the images, and as a result of the processing, 81 digital images were arranged in a sequence in which the results of this step were verified. The points cloud after processing were 1,082,617 points. Six control points were selected, used as distances constrained. The validity of the fixed location of the points can be ascertained by checking the data. The program provide the error and accuracy for each image, where a total error in the scale bar was 0.005253 meters, a total error of marks points was 0.010957 meters and the accuracy for all six points was 0.005 meters.

<p><strong>Abstract.</strong> In the past two decades or so, digital tools have been slowly integrated as part of the archaeological process of information acquisition, analysis, and dissemination. We are now entering a new era, adding the missing piece to the puzzle in order to complete this digital revolution and take archaeology one step further into virtual reality (VR). The main focus of this article is the methodology of digital archaeology that fully integrates virtual reality, from beta testing to interdisciplinary teamwork. We briefly discuss data acquisition and processing necessary to construct the 3D model, the analysis that can be conducted during and after the making or creation of the 3D environment and the dissemination of knowledge. We explain the relevance of this methodology through the case study on the intendant’s palace, an 18th century archaeological site in Quebec City, Canada. With this experience, we believe that VR can prompt new questions that would never have occurred otherwise and can provide technical advantages in terms of gathering data in the same virtual space. We conclude that multidisciplinary input in archaeological research is once again proven essential in this new, inclusive and vast digital structure of possibilities.</p>

Retrieving images from large and varied collections using image content is a challenging problem. This paper presents a novel method for cultural relic image retrieval algorithm by integration of multiple cues. The preprocessing of the images makes it possible for correct retrieval and classification of images even when they are deformed by transformation of rotation, scaling and translation or a combination of these. In feature representation, a method combining both color and shape features of image is proposed to improve the retrieval performance. A modified principal component analysis is used to select a subset of variables that well represents the data thus improved the retrieval efficiency. The proposed method is made application in the digital archeology museum. The results demonstrate that the system is both effective and efficient.

Full textAbstract:
Technology of aerial laser scanning is often well used for a DTM generation. The DTM (digital surface model) displayed in appropriate form, e.g. shaded surface, can be used as a data source for searching for archaeological sites. Aerial laser scanning data acquisition is unfortunately too expensive for non-commercial projects. It can be solution to use the ALS data acquired primarily for another reason by public service. This data has in general lower density, than expensive custom-made data, but can be borrowed for research purpose in a limited size. We tested the data from The Czech Office for Surveying, Mapping and Cadastre. The aim was to find, if it is possible to use data characterized by density of about 1 point/m2 for archaeological research. We used the DTM in form of shaded surface and inspect the data around few well known archaeological sites from different periods. It is also possible to use different outputs from the original DTM to better display terrain discontinuities, which could be caused by human activity.

Full textAbstract:
Abstract This article focuses on the role of “skeuomorphic technologies” and “skeuomorphs of practice” in the development of digital workflows in archeology, seeking to examine whether there are common trends toward skeuomorphism in our development of digital infrastructures. By considering the way in which GIS, tablet, and 3D technologies were integrated into the digital field recording at the sites of Çatalhöyük in Turkey and Kämpinge in Sweden, we argue that skeuomorphic emulation may form an essential part of the process of “controlling” “socializing” new digital technologies and ultimately transforming digital practice. Ultimately we contend that a field approach that explicitly takes into account skeuomorphism as a crucial element of transformation is more likely to encourage the development of practices, which go behind the traditional investigation paradigms. Understanding the role of skeuomorphism as a mode of socializing technology (see below) within the broader framework of the development of digital field practices can help us to critically address the process of transformation of practice and identify new methodological directions.

This article considers the continuities afforded by digital platforms for reactivating the 1990s Transgender Nation politics, by providing a means to bond like-minded people into imagined nations cohered into an affective public. The media archeology approach facilitates the investigation into stylistic and conceptual continuities between the 1992 and 1994 Transgender Nation’s “direct action” and militant politics into cases of digital activism from 1995 until 2016. The article further tracks early queer and trans connection and discord into later digital incarnations. The author considers digital culture as a significant site for personal and group transformation, but finds in the touchstone activities of Transgender Day of Remembrance an imagined community styled by necropolitical attunements. Direct actions online are still fueled by contesting hostility to trans life, but the critique of transgender marginalization must also account for sexual and racial dynamics.

<p><strong>Abstract.</strong> Detailed mapping is essential to systematic archeological practice and is conducted in five stages: identification, evaluation and excavation, site preservation and documentation, analysis and interpretation, and education. As archeological mapping evolves the five stages remain the same, enhanced by the integration of new geoinformation technologies to better record archeological information. Even with technological advances essential spatial data and mapping products are often overlooked when archeological information reaches the education stage. This disconnect occurs when artefacts are exhibited without considering communicating spatial context, i.e. presented behind glass cabinets. This is a critical concern as understanding spatial context is essential to grasping heritage site histories. As a solution to this wide-reaching issue in geovisualization and the digital humanities, this research proposes a framework for developing immersive virtual reality heritage site applications that preserve the spatial context of archeological mapping. Applying the framework, this research produced the heritage site application “VR Riverbend”, which successfully relinks archeological materials with essential spatial context. Thus, VR Riverbend connects archeological data with place, remedying issues of artefact/context disconnect inherent in traditional exhibits. Developing immersive VR heritage site applications following the introduced framework provides a solution towards effective spatial and often multi-layered archeological heritage site education.</p>

Full textAbstract:
Archaeological data are usually inherently incomplete, heterogeneous, discontinuous and require frequent updates and possible adjustments. It is important to constantly create detailed documentation, which will precisely represent the actual situation. However, even the most precise figure is only an estimated representation of the documented object. Therefore, it is necessary to collect fully metric documentation and its professional archaeological interpretation. Acquiring correct and valuable underwaterdigital images for the archaeology purposes is not easy due to specific shooting conditions. It should be noted a number of limitations are unique to this type of imaging environment — the apparent extension of the focal length, the “disappearance” of colours, as well as a significant reduction in the transparency of the water environment. Therefore, the authors have made attempts to describe changes, in a much broader sense, in the quality of photogrammetric images that had been taken in various shooting conditions. Underwater and aerial images of two test fields were tested. First, the ground sampling distance of the INTOVA IC500 digital camera and the geometric accuracy of the acquired images were examined. Then, the impact of changes to the imaging conditions on the radio-metric resolution and colour projection were designated. In the last stage, the acquired images were used in practice — to assess the progress of the erosion process of an archaeological object, and also to comply its documentation in the form of vector drawing with the accuracy of mxy = ±0.5 mm. Keywords: photogrammetry and remote sensing, archaeology, underwater photogrammetry, resolution, ground resolved distance

Full textAbstract:
The field of archeology is undoubtedly left behind in the mobile era compared to other scientific domains. The deployment of mobile technology solutions is of meagre contribution to the field. In fact, almost no mobile apps are designed as per archeologists’ work requirements in the excavation site. This study aims to tackle this dilemma through a roadmap to pave the way for the community to recover this digital divide. The roadmap encompasses a comprehensive methodology on how to develop mobile apps that meet the requirements of its respective audience. The development of two apps is introduced to illustrate the implementation of the methodology. The result of adopting this ‘roadmap’ study improves the data collection, processing and usage. It enhances information accuracy and sharing. Besides, it reduces the ‘destructive’ aspect of the archeology investigations and provides archeologists with handy solutions that they can use ubiquitously. The refinement of the first versions of mobile apps for archeology will make the measurements more accurate and improve the level of maturity of the field vis-à-vis the mobile technology sector. Most significantly, this study opens the door, eventually, for a new era wherein the community starts by deploying mobile technology solutions to ultimately go beyond the current dating techniques, such as the radiocarbon dating method. An ultimate future work could be the exploration of developing mobile apps, in an interdisciplinary context, that measure the age of archeological items by few clicks and prepare the field for the forthcoming post-device era.

This paper analyzes Italian radio theatre evolution and its ability to put itself always in the middle between radio and other expressive media: theatre, cinema, comics, daily news, books and Internet. Starting from the analysis of the main evolutionary phases of this complex radio genre, this contribution illustrates the complexity of radio theatre as one of the treasures brought to light by media archeology, which lends itself almost naturally to disciplinary and media crossings. In this expressive format, belonging to media proto history, lurks a deeply complex nature and fervent creativity, which rediscovers in the ether an amplifier of the digital, a new space of expressiveness and diversification of its audience.

Nothing is as purely imaginary as the digital archive. Like a brilliant specter from the vast recesses of the cultural universe, the digital archive sweeps through the night skies of the mind, turning time’s past into real-time, lighting up spatial horizons with light-space, folding the historical past into the projected future, breaking down fixed boundaries, always following the unpredictable pathways of the awaiting imagination. Never really interested in truth-telling, nor particularly loyal to the concept of bunker archeology, the digital archive is that rarest of cultural phenomenon: a code matrix tracing an uncertain arc across the human condition, projecting retrieved memories into the present, here confronting the solid matter of reality with imaginary reconstructions of the past, there gathering speed as the code matrix is propelled forward by the gravitational force-fields of the surrounding planets of society, economy, and culture, always becoming in the process something more intense, more vivid, more purely imaginary.

PurposeThe purpose of this paper is to define and stimulate interest in a potential new specialty within the information science field.Design/methodology/approachSources on digital forensics and digital archeology are discussed, and the topic is examined critically from a librarian perspective. The author examines the possibility of an information science specialty pursuing the reconstruction of “digital palimpsests”, where data that later becomes historically significant has been deleted or partially overwritten on digital media.FindingsThe author identifies at least one key incident (the NASA moon landing tapes) where this potential field has already started to be defined. Examination of the literature indicates that emphasis in data recovery to this point has centered on the needs of law enforcement and disaster recovery rather than on the considerations of manuscript preservation, recovery, and curation. The author emphasizes the need for librarians to bring together the skills of multiple fields, especially that of information technology, in order to shape the tools needed to take the lead in “digital palimpsest” recovery.Originality/valueThe author asserts that the recovery of “digital palimpsests” will become important as digital archives age and society's position on what has historical value inevitably shifts. The author further asserts that members of the information science field must actively work to take ownership of the field before it is subsumed by information technology or another discipline less equipped to manage its nebulous considerations effectively.

The archaeological heritage is non-renewable, and any invasive research or other actions leading to the intervention of mechanical or chemical into the ground lead to the destruction of the archaeological site in whole or in part. For this reason, modern archeology is looking for alternative methods of non-destructive and non-invasive methods of new objects identification. The concept of aerial archeology is relation between the presence of the archaeological site in the particular localization, and the phenomena that in the same place can be observed on the terrain surface form airborne platform. One of the most appreciated, moreover, extremely precise, methods of such measurements is airborne laser scanning. In research airborne laser scanning point cloud with a density of 5 points/sq. m was used. Additionally unmanned aerial vehicle imagery data was acquired. Test area is located in central Europe. The preliminary verification of potentially microstructures localization was the creation of digital terrain and surface models. These models gave an information about the differences in elevation, as well as regular shapes and sizes that can be related to the former settlement/sub-surface feature.<br><br> The paper presents the results of the detection of potentially sub-surface microstructure fields in the forestry area.

AbstractThis essay examines the origin, permutations, potentials, challenges, and implications of two successive, collaborative public history research, teaching, and learning projects undertaken by the Department of History at Cleveland State University, Cleveland, Ohio, and the Department of History and Archeology at Maseno University, Kisumu, Kenya between 2014 and 2018. The two projects explored how opportunities created by the mobile revolution in Africa could be leveraged to generate new ways of acquiring historical information and knowledge between students and faculty in universities separated by enormous distances and by disparate social, economic, and political experiences. Specifically, the projects examined how the cellphone revolution could reshape the production and dissemination of knowledge about important sites, places, events, and people in modern Africa. The essay examines the conception and permutations of the two projects; identifies and explores their potentials and challenges; and proffers thoughts and suggestions that may guide similar future endeavors.

Abstract. Nowadays digital tools are booming. The evolution of the technologies used in archeology and in architecture is such that we are going more and more towards low cost and time saving. Indeed, today we can use free softwares in photogrammetry in order to make 3D surveys of architectural buildings. Fifteen years ago it only required the use of the 3D laser scanner, a very expensive technique.As part of the course reform of the second year at the national school of architecture and urban planning Tunisia in the course of descriptive geometry and perspective drawing, an experiment was conducted in order to introduce low cost photogrammetry using the free software 123 D catch by autodesk, 3DF Zephyr or Scann 3D on the mobile phone. The objective of this course is to make students experiment different techniques of representation such as photogrammetry, perspective drawing, using a mobile phone , a digital camera or a pen. The object of the representation is the Tunisian cultural heritage such as the archeological site of Carthage.

Creating 3-dimensional (3D) models of underwater scenes has become a common approach for monitoring coral reef changes and its structural complexity. Also in underwater archeology, 3D models are often created using underwater optical imagery. In this paper, we focus on the aspect of detecting small changes in the coral reef using a multi-temporal photogrammetric modelling approach, which requires a high quality control network. We show that the quality of a good geodetic network limits the direct change detection, i.e., without any further registration process. As the photogrammetric accuracy is expected to exceed the geodetic network accuracy by at least one order of magnitude, we suggest to do a fine registration based on a number of signalized points. This work is part of the Moorea Island Digital Ecosystem Avatar (IDEA) project that has been initiated in 2013 by a group of international researchers (https://mooreaidea.ethz.ch/).

Peng Xi county, Sichuan province, the Bao Fan temple mural digitization survey mapping project: we use three-dimensional laserscanning, multi-baseline definition digital photography, multi-spectral digital image acquisition and other technologies for digital survey mapping. The purpose of this project is to use modern mathematical reconnaissance mapping means to obtain accurate mural shape, color, quality and other data. Combined with field investigation and laboratory analysis results, and based on a comprehensive survey and study, a comprehensive analysis of the historical Bao Fan Temple mural artistic and scientific value was conducted. A study of the mural’s many qualities (structural, material, technique, preservation environment, degradation, etc.) reveal all aspects of the information carried by the Bao Fan Temple mural. From multiple angles (archeology, architecture, surveying, conservation science and other disciplines) an assessment for the Bao Fan Temple mural provides basic data and recommendations for conservation of the mural. <br><br> In order to achieve the conservation of cultural relics in the Bao Fan Temple mural digitization survey mapping process, we try to apply the advantages of three-dimensional laser scanning equipment. For wall murals this means obtaining three-dimensional scale data from the scan of the building and through the analysis of these data to help determine the overall condition of the settlement as well as the deformation of the wall structure. Survey analysis provides an effective set of conclusions and suggestions for appropriate mural conservation. But before data collection, analysis and research need to first to select the appropriate scanning equipment, set the appropriate scanning accuracy and layout position of stations necessary to determine the scope of required data. We use the fine features of the three-dimensional laser scanning measuring arm to scan the mural surface deformation degradation to reflect the actual state of the mural surface patch model. For the degradation of the surface of the pigment layer, we use the patch model to simulate the scan obtained from an analysis. Statistics calculated relatively objective mural surface area from volume data, providing more accurate quantitative data for the mural conservation, especially, providing a viable technology for accurate monitoring of continued degradation. <br><br> We believe, in order to make use of the three-dimensional laser scanning technology in a digital heritage conservation application, the technology should not only be used to record the object geometry and play a role in record keeping aspects, but, rather, should be used during the investigation to protect against targeted degradation and a more meaningful interpretation function. Like the development of the medical application of X-ray technology not only retains a picture, but more importantly, through this technical interpretation of patient pathology, guides doctors in carrying out the treatment work. Therefore, in the process of digitization of cultural heritage research, the focus should shift to the use of digital technology in the analysis of heritage object degradation and degradation monitoring surveys can promote the application of digital technology in the conservation of cultural heritage.

This paper illustrates the results of an experimentation carried out by a multi-disciplinary research group made up of researchers from ITC-CNR of L'Aquila and of archaeologists of the University of L'Aquila. The research project carried out by the team is based on the analysis of the archaeological heritage (in particular, the documentation of some burials found in the medieval site of <i>Amiternum</i>, near L'Aquila). This starts from methods based on digital photogrammetric restitution, based on Structure from Motion (SfM) algorithms, and the generation of photorealistic textures in order to manage, in a 3D GIS environment, complex archaeological and anthropological data. The choice of technology to use is often determined by the specific needs of the survey, the purpose of the project, the budget and experience of the researchers, and the geometric characteristics of the assets, rather than the precision to be achieved. For the survey of the archaeological excavation of the medieval site of <i>Amiternum</i>, it was decided to use digital photogrammetry given that the objective was to document, with a rapid survey compatible with the times of an archaeological excavation the phases of image acquisition, processing and post processing of the site model. Furthermore, thanks to the integration of two technologies, digital photogrammetry and GIS, and the undisputed improvement in the management of 3D data by the GIS, three-dimensionality, in archeology in general, has become an indispensable component for site interpretation and for the documentation of the data.

Virtual models’ production is of high pertinence in research and business fields such as architecture, archeology, or video games, whose requirements might range between expeditious virtual building generation for extensively populating computer-based synthesized environments and hypothesis testing through digital reconstructions. There are some known approaches to achieve the production/reconstruction of virtual models, namely digital settlements and buildings. Manual modeling requires highly-skilled manpower and a considerable amount of time to achieve the desired digital contents, in a process composed by many stages that are typically repeated over time. Both image-based and range scanning approaches are more suitable for digital preservation of well-conserved structures. However, they usually require trained human resources to prepare field operations and manipulate expensive equipment (e.g., 3D scanners) and advanced software tools (e.g., photogrammetric applications). To tackle the issues presented by previous approaches, a class of cost-effective, efficient, and scarce-data-tolerant techniques/methods, known as procedural modeling, has been developed aiming at the semi- or fully-automatic production of virtual environments composed of hollow buildings exclusively represented by outer façades or traversable buildings with interiors, either for expeditious generation or reconstruction. Despite the many achievements of the existing procedural modeling approaches, the production of virtual buildings with both interiors and exteriors composed by non-rectangular shapes (convex or concave n-gons) at the floor-plan level is still seldomly addressed. Therefore, a methodology (and respective system) capable of semi-automatically producing ontology-based traversable buildings composed of arbitrarily-shaped floor-plans has been proposed and continuously developed, and is under analysis in this paper, along with its contributions towards the accomplishment of other virtual reality (VR) and augmented reality (AR) projects/works oriented to digital applications for cultural heritage. Recent roof production-related enhancements resorting to the well-established straight skeleton approach are also addressed, as well as forthcoming challenges. The aim is to consolidate this procedural modeling methodology as a valuable computer graphics work and discuss its future directions.

Terrestrial laser scanning (TLS) is the technique able to acquire the dense three-dimensional (3D) coordinates effectively over entire surfaces of the objects using laser pulses. Recently, TLS is often used in various fields such as civil engineering or archeology for object modeling, volume survey of tunnel, geographic information system (GIS), and the purpose to conserve the detailed shapes of cultural heritages. However, though its applications are extended continually, an application for system identification and structural health monitoring is a beginning stage. To improve the quality of data for the model based on TLS coordinate information, the digital elevation model (DEM) constructing method is applied. In a practical point of view, since there is no need to place a strain or stress sensor to a structure to be monitored, this model could has many advantages such as no in situ instrumentation of sensors, no difficulties to reach structures or structural members, independence of natural light source and no wiring cost. For the verification of this model, experimental tests are performed with a continuous steel beam subjected to point loads.

O intuito deste artigo é apresentar uma metodologia para o monitoramento de sítios arqueológicos visando à conservação preventiva de pinturas rupestres. Para tal, foram estudadas as metodologias de Processamento e Análise Digital de Imagens (PADI), que foram aplicadas ao contexto das pesquisas em Arqueologia. O monitoramento consistiu no registro fotográfico periódico (uma vez ao mês durante dois anos) de determinados conjuntos de pinturas de sete sítios arqueológicos localizados no Parque Nacional Serra da Capivara. As imagens obtidas foram comparadas por meio de seus histogramas. Um dos resultados foi uma métrica de medição por meio da contagem dos pixels das imagens. A metodologia de monitoramento, apesar de ainda estar nos seus primeiros testes, apresentou-se eficiente e promissora na identificação de alterações no suporte rochoso e nas pinturas rupestres. Abstract: The aim of this article is to present a methodology for the monitoring of archaeological sites aiming at the preventive conservation of cave paintings. For this, the methodologies of processing and digital image analysis - PADI - were studied and applied to the context of the researches in Archeology. The monitoring consisted of the periodic photographic record (once a month for two years) of certain sets of paintings from seven archaeological sites located in the Serra da Capivara National Park. The images obtained were compared by means of histograms. One of the results was a measurement metric by counting the pixels of the images. The monitoring methodology, although still in its first tests, was efficient and promising in the identification of alterations in rocky support and rock paintings.

<p><strong>Abstract.</strong> Archaeology as a science is based on finding and displaying the remains of the past. In recent years, with the progress of technology, the science of archeology has been expanding and evolving. Three-dimensional digitization has become an integral part of the archiving, documentation and restoration effort of cultural heritage, offering important benefits in studies for reconstruction and restoration tasks of architectural creations, archaeological sites, historic monuments and objects of art in general. The three-dimensional models are now available for many applications. In this paper such 3D models of two prominent Macedonian tombs in Northern Greece were exploited for their virtual restoration. Virtual restoration of monuments is of special importance to archaeological research, as it provides the necessary tools to investigate alternative solutions to the serious issue of archaeological restoration. These solutions do not interfere with the real monument, thus respecting its value and the international conventions. Digital 3D models have begun to be more beneficial in a science such as archaeology as they offer easy access to both archaeological and geometric information to a wider audience as well as a high degree of interaction possibilities with the user.</p>

For media scholars, locating the old in the new helps to debunk the inflation around the “newness” of contemporary media. Several approaches have been put to work in the exploration of these multiple temporalities within media: remediation, media revival, residual media, media archeology. In this article, we explore another temporal concept—hysteresis—as a way to think through the folding of time within and across media. The first part of the article presents a theoretical overview of the concept of hysteresis, from the field of experimental sciences in the late nineteenth century to Marx, Bourdieu, Baudrillard and others in the social sciences. In the second part, we introduce the concept of “media hysteresis” and illustrate it with two examples: the design of the keypad by Bell System’s push-button phones and the QWERTY keyboard. In the third and final part, we weave the concept of media hysteresis through a discussion of some of the major changes in cinema. More specifically, we examine how the aesthetic of the analogue persists in digital media and how media hysteresis can be useful to apprehend the celluloid revival. Our main argument throughout the article is the need for a theory of asynchronous simultaneity to analyse persistence and continuity across technological changes.

Full textAbstract:
The analysis of dental wear, at both the microscopic and macroscopic scale, is one of the most widely used tools in archeology and anthropology to reconstruct the diet and lifestyle of past human populations. Biomechanical studies have indicated that tooth wear helps to dissipate the mechanical load over the crown surface, thus reducing the risk of tooth fracture. To date, there are only a few studies that have examined functional tooth wear variation in modern humans. Here we propose to study masticatory efficiency through the use of the Occlusal Fingerprint Analysis method, a well-developed digital approach that allows the reconstruction of the occlusal dynamics occurring during mastication. The aim of this study is to provide the first longitudinal quantitative data of molar and premolar macrowear patterns within a functional context. We examined the mixed and permanent dentition of one Australian Aboriginal child (from ages 8 to 17) from Yuendumu, using high-resolution surface scans of dental casts including both upper and lower arches. Our results suggest that the occlusal macrowear patterns of this individual did not significantly change through time. Occlusal contact parameters such as functional area, inclination and direction remain relatively unaltered throughout childhood and adolescence, indicating little change in the masticatory function of this individual. The functional tooth wear pattern in this individual did not change longitudinally indicating the degree of masticatory efficiency has most probably remained unaltered.

Context: Estimation of facial height and nasal length from digital photography is important to evaluate and planning surgical treatment of facial trauma, facial defect and post traumatic deformity. So facial height and nasal length values are of great use in plastic surgery and reconstructive surgery. These values are also important for identification of a person in forensic anthropology and archeology. The reliability of estimation of facial height from nasal length by using multiplication factor is high. The values of facial height and nasal length vary among populations. Materials and Method: This is a cross sectional, analytical type of study conducted in the Department of Anatomy, Sir Salimullah Medical College, Dhaka from January 2010 to June 2011. One hundred (100) Bangladeshi 25 to 45 years old women were selected for the study. Fourth class female employees of Sir Salimullah Medical College and Mitford Hospital and part time housemaids of Mitford area were selected by purposive sampling as study subjects. Results: The values of facial height and nasal length were 17.949 ± 1.3111cm and 5.179 ± 0.5349cm respectively. Multiplication factor for measuring facial height from nasal length was 3.49 ± 0.2864 (Mean ± SD). No significant difference was found between the measured and estimated facial height from nasal length. Conclusion: The anthropometric base line data of different facial dimensions might help the surgeons in diagnosing and treating reconstructive cases DOI: http://dx.doi.org/10.3329/bja.v11i2.20669 Bangladesh Journal of Anatomy, July 2013, Vol. 11 No. 2 pp 50-53

This paper examines the issue of quality assessment of tourism products, as one of the key elements of counntries’ touristicoffer in a rapidly changing digital and globalized world. Tourism product is a presentation of a broad cross-section of history, nature, archeology, living culture, ensuring that visitors taking part in the discovery will leave with a lasting impression of the diversity, complexity and beauty of the visited country and its culture. As such, it is a product of quite a particular nature, which derives from the coexistence of a series of different elements interlinked among each other. It is the combinations of interlinkages that enable destinations to offer an individualized “total tourism product” that meets the changing needs of various categories of tourists. Total tourism products are complex and are shaped in different offered through numerous and diverse specific products and services,which may be shaped in many different ways and for which demand exists on a combination of motives, often in conflicting mutual interlinkages. The assessment of the quality of tourism offers is a complex process, which focusses around the tourists. The concept of valorization of tourist sites and attractions is a useful tool in the quality assessment. The harsh completion in the field for tourism calls for application of the total quality management system, which improves the ability of the tourism sector to meet the needs and requirements of the tourists, at minimum costs. Creation and introducing quality standards would be an urgent task, which is the responsibility of both businesses and institutions alike.

Scientific datasets have immeasurable value, but they lose their value over time without proper documentation, long-term storage, and easy discovery and access. Across disciplines as diverse as astronomy, demography, archeology, and ecology, large numbers of small heterogeneous datasets (i.e., the long tail of data) are especially at risk unless they are properly documented, saved, and shared. One unifying factor for many of these at-risk datasets is that they reside in spreadsheets.In response to this need, the California Digital Library (CDL) partnered with Microsoft Research Connections and the Gordon and Betty Moore Foundation to create the DataUp data management tool for Microsoft Excel. Many researchers creating these small, heterogeneous datasets use Excel at some point in their data collection and analysis workflow, so we were interested in developing a data management tool that fits easily into those work flows and minimizes the learning curve for researchers.The DataUp project began in August 2011. We first formally assessed the needs of researchers by conducting surveys and interviews of our target research groups: earth, environmental, and ecological scientists. We found that, on average, researchers had very poor data management practices, were not aware of data centers or metadata standards, and did not understand the benefits of data management or sharing. Based on our survey results, we composed a list of desirable components and requirements and solicited feedback from the community to prioritize potential features of the DataUp tool. These requirements were then relayed to the software developers, and DataUp was successfully launched in October 2012.

Abstract. The infrared (IR) imagery provides additional information to the visible (red-green-blue, RGB) about vegetation, soil, water, mineral, or temperature, and has become essential for various disciplines, such as geology, hydrology, ecology, archeology, meteorology or geography. The integration of the IR sensors, ranging from near-IR (NIR) to thermal-IR through mid-IR, constitutes a baseline for Earth Observation satellites but not for unmanned airborne vehicles (UAV). Given the hyperspatial and hypertemporal characteristics associated with the UAV survey, it is relevant to benefit from the IR waveband in addition to the visible imagery for mapping purposes. This paper proposes to predict the NIR reflectance from RGB digital number predictors collected with a consumer-grade UAV over a structurally and compositionally complex coastal area. An array of 15 000 data, distributed into calibration, validation and test datasets across 15 representative coastal habitats, was used to build and compare the performance of the standard least squares, decision tree, boosted tree, bootstrap forest and fully connected neural network (NN) models. The NN family surpassed the four other ones, and the best NN model (R2 = 0.67) integrated two hidden layers provided, each, with five nodes of hyperbolic tangent and five nodes of Gaussian activation functions. This perceptron enabled to produce a NIR reflectance spatially-explicit model deprived of original artifacts due to the flight constraints. At the habitat scale, sedimentary and dry vegetation environments were satisfactorily predicted (R2 > 0.6), contrary to the healthy vegetation (R2 < 0.2). Those innovative findings will be useful for scientists and managers tasked with hyperspatial and hypertemporal mapping.

Archeology is the only branch of human study that relies more on material remains left by people than on direct observation of human behavior or on written evidence. This focus on material evidence compels archaeologists to improve the methods and techniques of collecting and interpreting data that ensure the extraction of maximum information from available sources. The article provides an analysis of existing national and foreign information and geoinformation systems representing data on archaeological finds, cultural sites, and research documentation. A description of the existing standards, which regulate the list of attributes of geoarchaeological objects, is provided. The article also describes the stages of conceptual and logical modeling of the “ArchaeoNomos” database, which represents a unified repository for all data accompanying archaeological investigations, archaeological research and design, and documentation of research activities of the Scientific Research Center “Baikal Region” of Irkutsk State University. The problem of automating the processes of storage, processing, modification, and interpretation of geoarchaeological data is formulated. The system analysis of the subject area, system specification of an application that works with a database, the surveying specialists of the subject area to identify associations between database objects are presented. The infological and physical models of data presentation in the database are described, which allows the integration of the accumulated archaeological data into larger scientific associations. Finally, the advantages and disadvantages of using relational databases as repositories for archaeological data are outlined. The purpose of creating the “ArchaeoNomos” database is to implement measures for the preservation of the archaeological heritage, including the introduction and the use of the database by scientists that systematize and automate access to accumulated scientific data, including literary sources. The sub-goals include solving the problem of organizing and storing archaeological data, implementing multilingual interfaces in the information system, organizing information support for field and laboratory archaeological research, transferring the physical (nondigital) historical data storage system to a digital system. “ArchaeoNomos” database allows to keep records, analyze, visualize, and interpret data on geoarchaeological sites of Irkutsk and the Irkutsk region.

Culture, cultural policies and cultural diplomacy of the 21st century acquire the status of a strategic political determinant, both in internal political aspect and within the frames of foreign policies. Culture is a component of building relations of trust and approximation, but also a ground for misunderstandings and conflicts that may occur between different cultures and religions. The cultural diplomacy can be an еxtremely useful instrument for prevention of conflicts and crises, especially where the political and economic conflicts are followed by religious and cultural confrontations and crises. The role in the rehabilitation and the return to normal life in the regions of wars and armed conflicts is indisputable. Peace as the highest and most valuable benefit of civilization has never been lasting and for ever-gaining global reality. For certain regions and districts the absence of peace has become their most deficient factor for decades. If the cultural diplomacy has the power to prevent and rehabilitate the serious disturbances of peace and peaceful international coexistence of peoples, states and religions, it certainly can be one of the most important components and instruments in building аssumptions for lasting and sustainable peace on the contemporary international scene. The global peace, the minimization of the numerous open regional war hotspots, the whole world economic and social development in conditions of necessary consensus of the opposed interests, must in itself contain components of culture and cultural diplomacy. The culture informs, creates, connects, converges, and in conditions of irreconcilable social exclusivities and xenophobia can be an irreplaceable tool in the processes of social cohesion. Numerous educational forms, musical, fine arts, literary contents, TV and radio, films, theatres and ballet, archeology and cultural heritage, language as an indispensable instrument for understanding, up to the newest forms of digital cultural action through the largest global medium, internet, are inevitable and vitally important factor for solution of post-conflict and post-crisis situations This study, by referring to specific examples on building assumptions for lasting and sustainable peace, takes into consideration numerous activities of cultural diplomacies of states, international organizations, non-governmental and civil societies.

Goal. The purpose of the work is to develop an aerial photography complex based on a DJI S1000 helicopter UAV for aerial photography, which includes a laser scanner (LS) and a digital camera (CPC). Method. For several decades, aerial photography has been an effective tool for geodetic works, geophysical surveys and various types of monitoring. On the other hand, the use of not only digital imaging, but also laser scanning of objects allows to maximize the accuracy of obtaining the coordinates of points on the ground and eliminate such a process as plan-height binding in the field, which occupies more than 80 % of field work that is, much cheaper the process of creating cartographic materials. In addition, the use of laser scanners on board unmanned aerial vehicles helps to solve a number of scientific and applied problems in various fields, such as engineering research, environmental monitoring, landscape research and modeling, construction, architecture, archeology and more. Comprehensive study, research and monitoring of the environment involves the availability and use of highly efficient modern technologies, special software for data processing and analysis and qualified human resources. Aerial laser scanners are the latest high-precision technology for obtaining data about the object by noncontact method and have a multi-purpose purpose. I have been actively using them in the world since the early 2000s. They have a number of advantages over traditional aerial photography. Drugs are manufactured by the world’s leading companies, they are available on the market and are in great demand among foreign specialists. Unfortunately, in Ukraine, airborne laser scanners are used in limited quantities to perform special tasks with the involvement of foreign experts. In this area we have a significant lag compared to other European countries. Therefore, the acquisition and application of such a software and technology complex and UAV will help solve and accelerate the solution of many important scientific and applied problems in Ukraine, as well as increase the potential, opportunities and prestige in domestic and world science and practice. Results. A mock-up model of installation and implementation of Velodyne VLP-16 on a DJI S1000 helicopter UAV has been developed. The authors analyzed the known systems and created the best option for connecting and connecting the elements, which made it possible to simplify the layout of the devices, which in turn made it possible to reduce the cost of the proposed complex. Scientific novelty and practical significance. For the first time in Ukraine, a method of installing a helicopter-type UAV was developed and proposed. With the help of an airborne laser scanning system installed on board an unmanned aerial vehicle of helicopter type it is possible to solve a number of important scientific and applied tasks, such as: monitoring the technical condition of large and hard-to-reach structures – nuclear, hydro and thermal power plants, power lines, etc. ; monitoring the condition of roads, detecting places of surface damage and other dangerous places in order to prevent car accidents; detection of damage to forests and agricultural lands; observation and prevention of landslides in mountains and industrial quarries, places of soil erosion; monitoring of water resources, changes in contours and heights of the coastal strip; detection of roof defects, deformations, wall cracks on highrise buildings for architectural measurements, 3D modeling, documentation and preservation of cultural heritage sites; assistance in archaeological exploration to identify archaeological sites and study artifacts. In addition, peripheral drugs can be installed on other moving objects (cars, railcars, boats, etc.) and scanning from fixed bases in stationary conditions.

A long-lasting open question in the field of Galactic archeology refers to the size of the contribution from former globular cluster (GC) stars to the formation of the stellar halo of the Milky Way. We contribute to answering this important question by establishing observational links between the present-day halo field star population and GCs. To this end, we combined astrometric information such as space motions and parallaxes from the second data release of the Gaia mission (Gaia DR2) with spectroscopic radial velocities and metallicities ([Fe/H]) from the Sloan Digital Sky Survey (SDSS-IV, DR14) to end up with a seven-dimensional chemodynamical information space for more than 3 × 105 stars. Moreover, from our previous study, we incorporated the sample of halo giant stars with a distinct chemical signature (strong CN bandheads) that resembles the light-elements anomaly otherwise only seen in the second generation of globular cluster stellar populations. Using three different tagging techniques – among which is the exploration of conservative integrals of motion – we are able to establish unique associations between 151 extratidal stars in the neighborhood of eight GCs, which coincide with earlier findings of stellar envelopes beyond the tidal radius and even beyond (out to several tens of tidal radii). In addition, we trace the possible origin of about 62% of the sample of CN-strong giants to their potential host clusters. We find a connection between several of the involved GCs and the Gaia-Enceladus and Sequoia merger events. By establishing kinematic and chemical connections between 17 CN-strong stars and their surrounding fields, we identify co-moving groups of stars at the same [Fe/H] with a possible cluster origin. Some of these associations contain RR Lyrae variables, which allows meaningful distance inferences to be made. From these, we find strong evidence that four CN-strong stars and their associates are connected to the Sagittarius stream whilst their tightly confined [Fe/H] may hint to a birth site in M 54, the massive cluster in Sagittarius’ core remnant. Finally, by employing the counts of CN-strong and bona-fide CN-normal giants from our novel sample, we provide tentative estimates for the fraction of first-generation cluster stars among all stars lost to the halo. In the immediate cluster vicinity, this value amounts to 50.0 ± 16.7% while the associations in the halo field rather imply 80.2−5.2+4.9%. We speculate that – if proven real by spectroscopic follow-up – the disparity between these numbers could indicate a major contribution of low-mass clusters to the overall number of stars escaped to the halo or could alternatively suggest strong mass loss from the first generation during early cluster dissolution.

Wooden ships and digital wrecks. A reflection upon the development and future of maritime archaeology in The Netherlands. This paper explores the development of the Dutch maritime archaeological research tradition, the current status of the discipline, and its future perspective. To that end, the focus is mainly on the most important maritime archaeological entity: the shipwreck. Many of the Dutch shipwrecks have been found and studied in the former seabed of the Zuiderzee (the current polders of the province of Flevoland). Ever since the 1940s, shipwrecks have been examined in this region. Until the beginning of the 21st century, many of these wrecks were studied in a more or less traditional (analogue and manual) way. Nowadays, traditional and modern excavation techniques and methods are combined for fast, accurate and detailed research results. We should realize that, whereas the quality of maritime archaeological research will improve over the next 25 years, the preservation quality of the shipwrecks will continue to decrease due to soil disturbance, dehydration and decompression. Therefore, future maritime archaeological developments should focus not only on research techniques, but also on new and better methods that will help to prevent a further deterioration of the Dutch wrecks.
