Abstract:
Archaeologists, historians, and art historians are increasingly turning to three-dimensional computer modeling to create dynamic visualizations of ancient monuments and urban spaces, but the resulting 3-D content is not always accepted as scholarship and integrated into discipline-specific dialogue. In Digital Karnak: An Experiment in Publication and Peer Review of Interactive, Three-Dimensional Content, Elaine A. Sullivan and Lisa M. Snyder propose a reconceptualization of computer modeling as a new means and form of knowledge production, offer a framework for peer review and publication of 3-D content, and describe an experiment to develop an innovative publication with an interactive computer model at its core. The Digital Karnak model, a geotemporal model of an ancient Egyptian temple, is their case study, a 3-D publication package of which they posted for peer review. This article describes the model's creation, the software interface used for the publication prototype (VSim), and the ways in which this project addresses the challenges of publishing 3-D scholarly content.

Abstract:
Abstract. Earth fissures are pervasive cracks that develop on valley floors as a consequence of land subsidence associated with extensive groundwater withdrawal. To capture geometrical, geological and geotechnical information of ground fissures is of paramount importance for their characterization. Recent advances in remote sensing techniques and the accessibility to remotely piloted aircraft systems (RPAS) as well as the evolution of onboard digital cameras enable the capture of digital photos and videos. Using digital photos along with the Structure from Motion (SfM) technique and following certain strategies, we can reconstruct a 3-D model of the earth fissures under study. This technique requires digital photos, but when a digital video is available, we can convert it into a set of frames and equally apply the procedure. Besides, the extraction of frames from a video assures a key condition for the SfM technique: the overlap between photos. The resulting 3-D model should be scaled and oriented using a rigid transformation matrix or even better including ground control points (GCP) into the captured photos or frames. The latter enables the geo-referencing of the point cloud and the correction of linear and non-linear deformations. In this work, the proposed methodology is illustrated through the application of SfM technique to a high-resolution video downloaded from YouTube (i.e. https://youtu.be/9xdAnftBKvY, last access: 20 February 2020). The video shows a mile-long earth fissure that appeared sometime between March 2014 and December 2014 near the Tator Hills (Arizona, USA) over Quaternary sediments. The Arizona Geological Survey captured these videos using an RPAS. The frames of the video were downloaded and extracted using a simple Matlab code. Then, we sub-sampled the frames and processed them using the software Agisoft Metashape Professional. Finally, we got metric data from Google Earth and generated a 3-D model. The quality of the 3-D model strongly depends on the quality of the photos and the GCP. However, this study shows the potential of this technique, instrumentation and data available on Internet for the development of 3-D point clouds and 3-D models for the detailed analysis of earth fissures.

Abstract:
AbstractGeological field mapping is a vital first step in understanding geological processes. During the 20th century, mapping was revolutionized through advances in remote sensing technology. With the recent availability of low-cost remotely piloted aircraft (RPA), field geologists now routinely carry out aerial imaging without the need to use satellite, helicopter, or airplane systems. RPA photographs are processed by photo-based three-dimensional (3-D) reconstruction software, which uses structure-from-motion and multi-view stereo algorithms to create an ultra-high-resolution, 3-D point cloud of a region or target outcrop. These point clouds are analyzed to extract the orientation of geological structures and strata, and are also used to create digital elevation models and photorealistic 3-D models. However, this technique has only recently been used for structural mapping. Here, we outline a workflow starting with RPA data acquisition, followed by photo-based 3-D reconstruction, and ending with a 3-D geological model. The Jabal Hafit anticline in the United Arab Emirates was selected to demonstrate this workflow. At this anticline, outcrop exposure is excellent and the terrain is challenging to navigate due to areas of high relief. This makes for an ideal RPA mapping site and provides a good indication of how practical this method may be for the field geologist. Results confirm that RPA photo-based 3-D reconstruction mapping is an accurate and cost-efficient remote sensing method for geological mapping.

Abstract:
Digitization of natural history collections for specimen accessibility, research, and posterity has been a major push in museums over the past decade. One increasingly common form of specimen digitization is three-dimensional (3-D) surface scanning. There are numerous 3-D scanners on the market, including visible light and laser surface scanners. However, mobility of the scanning device, mesh resolution, and texture fidelity are among the most prominent issues facing regular implementation of 3-D scanning procedures for research purposes. Morphometrics research involving the digitization of Xiphactinus at the Sternberg Museum of Natural History (FHSM) using a Creaform Go!SCAN 50 visible light 3-D surface scanner has necessitated the development of a workflow using this 3-D scanner and the associated VXelements software. This workflow maximizes model quality with minimal loss of speed or efficiency when scanning numerous specimens. Major components of this workflow include proper use of positioning targets, appropriate merging of multiple specimen scans, and how to perform post-processing on models without sacrificing model resolution or texture. The primary benefit of the Creaform 3-D scanner is hardware mobility, allowing for use on large exhibited specimens or digitizing specimens during research trips. Shortcomings include relatively low mesh resolution, (bottoming out at 0.5 mm), difficulty scanning highly complex structures, and low texture fidelity of scanned models. However, texture fidelity can be improved through use of the free software, Meshlab, by overlaying high-quality stacked photographs onto the 3-D mesh. Incorporating Meshlab texture overlays into the workflow allows for the production of digital models with improved color and textural data – ideal for accurate visualization of specimens in 3-D viewers for educational outreach and online databases. While not perfect for all applications, the Creaform 3-D scanner allows for rapid digitization of specimens in an increasingly digital collections environment, and is sufficient for some research applications. The workflow established at the FHSM can serve as a framework for other institutions to use the Creaform 3-D scanner to best suit their digitization needs.

Abstract:
Abstract Efficient, accurate data collection from imagery is the key to an economical generation of useful geospatial products. Incremental developments of traditional geospatial data collection and the arrival of new image data sources cause new software packages to be created and existing ones to be adjusted to enable such data to be processed. In the past, BAE Systems’ digital photogrammetric workstation, SOCET SET®, met fin de siècle expectations in data processing and feature extraction. Its successor, SOCET GXP®, addresses today’s photogrammetric requirements and new data sources. SOCET GXP is an advanced workstation for mapping and photogrammetric tasks, with automated functionality for triangulation, Digital Elevation Model (DEM) extraction, orthorectification and mosaicking, feature extraction and creation of 3-D models with texturing. BAE Systems continues to add sensor models to accommodate new image sources, in response to customer demand. New capabilities added in the latest version of SOCET GXP facilitate modeling, visualization and analysis of 3-D features.

Abstract:
The Onion Creek Diapir is one of many salt domes proximal to the Uncompahgre thrust front of the ancestral rockies in the Paradox Basin. It is comprised of Paradox Formation evaporites and large blocks of Honaker Trail Formation carbonates that were deformed by loading of Permian Cutler Formation progradational alluvial to fluvial fans. The history of salt movement in the Onion Creek Diapir is recorded in the near-salt strata. Large salt bodies and their adjacent mini-basins evolve conforming to a complex relationship between salt withdrawal, creating localized accommodation, and sediment deposition. Migrating mini-basin depo-centers, thinned and folded strata, and spatial facies trends reveal the relative rates of diapirism and sedimentation. The study area outcrop, north of the diapir, is divided by significant stratigraphic horizons that help define depositional periods. Six measured sections in the study area reveal higher preservation rates of fine grained floodplain deposits, typically destroyed in alluvial environments, than at locations correlating to stratigraphic levels high in the outcrop suggesting a low accommodation environment evolving into higher accommodation where stacked channel complexes are preserved. Preserved slump folding at the base of the outcrop reveals that although some salt emergence occurred in the earliest depositional period it was not significant enough to preclude sediment deposition or to divert the Cutler fluvial network and destroy floodplain facies. A 3-D digital outcrop, modeled from photogrammetric data, illustrates the development of localized accommodation, attracting fluvial channel in a near-salt, tight axial syncline during the later depositional period. These evidences suggest a greater emergence of the diapir and likely diversion of the Cutler channel complexes.

This article examines the synergy between aesthetic and technical issues surrounding current input and output modes applicable to digital sculpture built by means of additive fabrication technologies. The scope is limited to select sculptural aspects that either transcend, question or fall short when measured against traditional manufacturing and aesthetic modes. Presented are a range of technical as well as aesthetic aspects that have impacted on this ''new form'' of sculpture delivery. It is indicated that irrespective of current strengths and weaknesses, for the evolving sculptor, an interactive creative partnership between technologies equally positions this ''new form'' of sculpture delivery as a leading role player towards defining a new digital aesthetic.

Abstract:
The purpose of a pediatric cardiology consultation is to inform, or educate, the patient and family of all aspects surrounding a certain congenital heart defect. Consultation education methods and materials may include verbal descriptions, two-dimensional (2-D) heart diagrams, and take-home pamphlets. Because the human heart is a complex three-dimensional (3-D) object, the problem lies within the clarity to which these methods are performed by the doctors and understood by the patients and families. Therefore, during a consultation the cardiologist must a) possess the ability to describe a defect visually as well as verbally and b) ensure that the patient and family have a clear understanding of the situation. In this work a method to improve patient consultation is outlined. Heart model segmentation methods from Cardiac MRA images are discussed by using the Materialise Mimics 10.11 software. EduView, the proposed software application solution, provides the user with traditional verbal descriptions and 2-D heart diagrams along with the ability to interact with a digital 3-D human heart model. By including a 3-D approach, the purpose is to assist the cardiologist in explaining a defect while further educating the patient and family. Sun Microsystems Java technology was utilized in order to program the application. Implementation of the software solution is outlined and the results from two surveys involving parents of children with congenital heart defects and pediatric cardiologists are presented. This study outlines a proof of concept. There is significant potential for extending and marketing this tool for future clinical use.

Sugar cane is one of the crops with the highest level of water consumption, with a high evapotranspiration demand throughout most of its cycle. Knowledge of the sugar cane water demand, the time that irrigation should be applied, and how to irrigate the crop are becoming increasingly important for the sustainable development of irrigated sugar cane cultivation, especially in areas of low water availability, as it is the case in northea stern Brazil. The experiment was carried out at the Curu Experimental Field (property of the Embrapa Tropical Agroindustry), located in the Curu-Paraipaba Irrig ation Project, city of Paraipaba-CE (3 ° 29 '20''S, 39 ° 9' 45''W and elevation 30m), in order to determine the evapotrans piration and crop coefficients (Kc) of sugarcane (Saccharum L. officinarium), subsurface drip-irrigated. It was used the SP 6949 sugar cane variety, planted in a spacing of 1.8 m between double rows and 0.4 m between rows within the double row. As to t he irrigation, we used one lateral water line for each double row, buried at a depth of 0.15 m, w ith self-compensating drip emitters, with a flow rate of 1 L h-1, spaced 0.5 m on the water line. The crop was irrigated daily and there were three fertigations per week. The irrigation de pth was periodically adjusted, keeping the soil water potential between -8 kPa to -20 kPa. The crop evapotranspiration (ETc) was determined using a wei ghing lysimeter with a surface area of 2.25 m 2. The reference evapotranspiration (ETo) was estimated by the FAO Penman-Monteith method. The durations of the phenological stages of cane sugar were estimated through analysis of soil cover, with the use of digital images. Durations of 31, 49, 237 and 118 days were observed, respectively for initial, crop development, mid-season and late season stages. The yields achieved within and outside the lysimeter were respectively 144.4 and 108.8 t ha -1 . The total ETc observed during the cycle of the sugar cane was 1074.1 m m, with maximum values of 6.6 mm d-1 during the mid-season stage. Observed Kc values for initial, mid-season and late season stages were respectively 0.23, 1 .03 and 0.50. In the crop development stage, the relationship between Kc and the (crop) soil cover was represented with good accuracy by a negative quadratic model.
A cana-de-açúcar é uma das culturas com maior consumo de água, apresentando uma alta demanda evapotranspirativa ao longo da maior parte do seu ciclo. O conhecimento das necessidades hídricas da cana-de-açúcar, do momento de aplicação da água requerida pela mesma e a forma de aplicação torna-se cada vez mais importante para o desenvolvimento sustentável da sua produção irrigada, principalmente em regiões de pouca disponibilidade hídrica, como é o caso da região Nordeste do Brasil. O experimento foi conduzido no Campo Experimental do Curu, pertencente à Embrapa Agroindústria Tropical localizado no Perímetro Irrigado Curu-Paraipaba, município de Paraipaba-CE (3° 29’ 20’’ S, 39° 9’ 45’’ W e altitude de 30 m), com o objetivo de determinar a evapotranspiração e os coeficientes de cultivo (Kc) da cana-de-açúcar (Saccharum officinarium L.), irrigada por gotejamento subsuperficial. Utilizou-se a variedade de cana SP 6949, plantada no espaçamento de 1,8 m entre fileiras duplas e 0,4 m entre linhas dentro da fileira dupla. Na irrigação utilizou-se uma linha lateral para cada fileira dupla, enterrada na profundidade de 0,15 m, com gotejadores autocompensantes, com vazão de 1 L h-1, espaçados de 0,5 m na linha. A cultura foi irrigada com freqüência diária e foram realizadas três fertirrigações por semana. A lâmina de irrigação foi ajustada periodicamente, mantendo-se o potencial de água no solo entre -8 kPa e -20 kPa. A evapotranspiração da cultura (ETc) foi determinada utilizando-se um lisímetro de pesagem com área superficial de 2,25 m2. A evapotranspiração de referência (ETo) foi estimada pelo método FAO Penman-Monteith. As durações das fases fenológicas da cana-de-açúcar foram estimadas por meio da análise da cobertura do solo pela cultura, determinada com o uso de imagens digitais. Foram observadas durações de 31, 49, 237 e 118 dias, para as fases inicial, de desenvolvimento, intermediária e final, respectivamente. A produtividade alcançada dentro e fora do lisímetro foi de 144,4 e 108,8 t ha-1, respectivamente. A ETc total observada durante o ciclo da cana-de-açúcar foi de 1.074,1 mm, com valores máximos da ordem de 6,6 mm d-1 durante a fase intermediária. Foram observados valores de Kc iguais a 0,23, 1,03 e 0,50, para as fases inicial, intermediária e final, respectivamente. Na fase de desenvolvimento vegetativo a relação entre o Kc e a cobertura do solo pela cultura foi representada com bastante exatidão por um modelo quadrático negativo.

With the rapid development of information technology, the development of digital cameras is more rapid, the picture quality from the earliest hundreds of thousands of pixels to now to twenty, thirty million pixels, or even reach fifty million pixels. In recent years, digital cameras popularization range of lightweight portable, low cost of implementation, reusable and other advantages, so it is a large number of applications in close range photogrammetry, such as civil construction management, model reconstruction constructional, traffic accident scene reconstruction, monuments maintenance or many other GIS applications. In this study, a non-measuring single-eye digital camera was used to perform on-the-spot imaging of the petrochemical plant piping system. The captured image was generated by the 3D modeling software and the relevant information was obtained. Then the pipeline point cloud was compared with the original image and corrected. The three-dimensional pipeline model and pipeline database are established in a semi-automatic manner, and a piping management and maintenance system is created to enable piping users and maintenance and maintenance personnel to obtain the latest and most accurate piping configuration information and related attributes in this data system.

Abstract:
As a topic, organization design is poorly understood. While it is featured in most management textbooks as a chapter dedicated to organizational structures, it is unclear whether organization design is a one-off event or an ongoing process. Thus, it has traditionally been understood to be the same as an organizational configuration, with neat lines of communication and distribution of responsibilities, following pre-set typologies. However, what can be said to constitute organizational structure in this first half of the 21st century? The extraordinary growth of digital communications, the decreasing relevance of hierarchical bureaucracies, and the general demise of command-and-control have all but decimated the traditional notion of organizational structure. In this book it is argued that organization design needs a theoretical revamping. Using a mix of design and social sciences theories and concepts, the new approach is divided into three parts: design logics, design processes, and design leadership. A generic definition of organization design logics is offered, as a set of beliefs shared by managers and entrepreneurs in given sectors of the economy about the way organizations should be designed. Five logics and three types of designing processes are put forward. Logics: (1) the identity logic, (2) the normative logic, (3) the service logic, (4) the logic of effectual reasoning, (5) the logic of interactive structure. Processes: (1) intended design, (2) emergent design, (3) perceived design. For the leadership part, a model of leaderful organization design(ing) is proposed, with the following distinguishing features: (a) practice-based, (b) guided by values of democratic participation, (c) places meaning-making and meaning-taking at the centre of organizational life, (d) driven by design logics, which can be adopted and adapted to suit different internal and external environments.

AbstractThe questions of whether and how doctoral students are motivated for enhanced research collaboration deserve thorough consideration. Even though collaboration in general and its mediated forms, such as computer-supported cooperative work and collaborative learning (CSCW and CSCL), are prominent research topics, only a little is known about the methods necessary to design various activities to support research collaboration. With the upcoming generation of tools such as Mendeley, Conference Chair, ResearchGate, or Communote, scholars suspect that web 2.0 services play a decisive role in enabling and enhancing research collaboration. However, there is almost no data available on the extent to which researchers adopt these technologies, and how they do so. Therefore, the authors first present an overview of the current usage of web 2.0 among doctoral researchers in their daily academic routines, based on a survey (n = 140) conducted in the German Federal State of Saxony. It confirms a wide and often specified usage of web 2.0 services for research collaboration. For theoretical analysis, the authors propose a conceptual framework that reflects the requirements of scientific participation and scholarly collaboration within an average international doctoral programme adopting current digital technologies. The aim of this framework is to understand, support, and enhance research collaboration among doctoral researchers. Our fish model highlights the mutual relationship between the following dichotomous factors: (a) tasks/time factors; (b) beliefs/activities; (c) support/context; and (d) incentives/ethical issues. Our results indicate a significant relationship in terms of research collaboration. This relationship has particularly been identified between two dichotomous factors: beliefs/activities and incentives/ethics.

Abstract:
Recent improvements in technology of last generation mobile devices (smartphones, Personal Digital Assistants, Ultra-Mobile PCs) have opened up challenging new scenarios in 3-D ubiquitous visualization. Entertainment, cultural heritage, telemedicine, and distance learning are only a few of the disciplines that can take advantage of 3-D model visualization on mobile and hand-held devices. This chapter investigates the main methodologies used to display and navigate complex scenes and heavy datasets on mobile devices. Both local and remote rendering software techniques are considered with respect to solutions based on hardware acceleration. Moreover, issues related to the design of suitable graphics user interfaces are tackled. Finally, a solution for high performance visualization based on the remote rendering approach and enabling interactive manipulation of 3-D scenes composed by millions of polygons at 30 frames per second even on 50 Kbit/s wireless communication channels is presented.

Abstract:
The mortality rate of breast cancer can be effectively reduced by early diagnosis. Imaging modalities are used to diagnose through computer for women breast cancer. Digital mammography is the best imaging model for breast cancer screening technique and diagnosis. Digital breast tomosynthesis (DBT), a three-dimensional (3-D) mammography, is an advanced form of breast imaging where multiple images of the breast from different angles are captured and reconstructed (synthesized) into a three-dimensional image set. This chapter discusses the research work carried out on the computer diagnosis of women breast cancer through digital breast tomosynthesis and concludes with further improvement in the computer-aided diagnosis.

Abstract:
This chapter examines some ways information technologies (IT) are deployed in higher education courses to help learners create robust mental models. In e-learning, mental models are created through the following: digitally mediated (1) information visualization work; (2) virtual immersion, and (3) human interactivity. For (1) information visualization work, information technologies afford multi-sensory learning channels: texts, visuals, slideshows, screen casts and animations, audio, video, interactivity, immersiveness, and simulations. IT supports the archiving of digital learning artifacts through eportfolios, digital gallery shows, and informational multimedia databases. (2) Virtual immersion has been enabled in 3-D interactive spaces where learners may experience multi-faceted learning. More complex simulations have also been created with animations and long-term continuous learning. To promote (3) human interactivity, IT reifies human intellects and perceptions, and social software uses “swarm intelligence” to support consensus-driven realities. IT creates contexts for co-learning and intercommunications. Collaborative pedagogical strategies—online teaching case studies, mock trials, facilitated games, and various assignments and assessments—highlight the multiple-views, multiple-realities of constructivist learning.

Abstract:
Interactive systems are no longer expected to be used in confined and predefined places. By increasingly taking advantage of the physical environment, interactive systems are becoming mixed, that is, merging physical and digital worlds. Moreover, they support user’s mobility and thus can be referred to as “mobile mixed systems.” To overcome technology-driven development processes and to take into account their physical nature and mobile dimensions, specific design approaches are required. From this perspective, we present the interweaving of an existing design model (ASUR) for mixed systems, and a 3-D environment (SIMBA) for simulating modelled mobile mixed system. The aims are to support the investigation of mobile mixed system design through the dedicated modelling approach, and to better understand the limit of the modelled solutions through their simulation. This constitutes a first step toward an iterative method of design for mobile mixed systems, based on “midfidelity” prototyping.

Abstract:
This chapter studies a composite stochastic model, in which the diffuse component arises from three dimensional (3-D) multipath scattering. That case occurs especially in dense scattering environments, in which the tall obstacles cause arrival of multipath power in the elevation plane, besides that arriving in the azimuth one. Also the multipath components are assumed to arrive at the mobile receiver in specific angular sectors at the azimuth receiver’s plane. The last is physically justified by multipath power blocking due to the channel obstacles (shadow fading), or/and lack of scattering objects at specific angular directions, or/and directional antennas utilization. An extended Suzuki model, where the Rician process for the diffuse scattering component is multiplied by a lognormal one, is considered as an appropriate composite model. The most important metrics of the model are presented, according to its assumptions. More specifically, from the closed form autocorrelation function, the Doppler power spectral density (PSD) of the diffuse component can be analytically derived. Afterwards exact solutions for the envelope and phase probability density functions (PDF’s) are presented. Exact solutions are also derived for the second order statistics, i.e. the level crossing rate (LCR) and the average duration of fades (ADF’s). An efficient deterministic simulation scheme will be presented, which implements the analytical model on a digital computer. Finally a curve fitting of the LCR to real world data, drawn from channel measurements, will demonstrate the flexibility and usefulness of the extended Suzuki model.

Abstract:
The aim of the chapter is to reflect on how ICT and digital tools and methodologies influence the study of architectural heritage, favouring interdisciplinary interactions. First, the chapter analyses the characteristics of digital heritage from real built contents in relation with the general concept of heritage. Then, it discusses the communicative characteristics of 3-D digital models and the related issues, common among the different disciplines. Finally, it presents the peculiar aspects of architectural heritage and the building information modeling applied to architectural heritage as a specific kind of digital procedure naturally born for this kind of heritage. In conclusion, it highlights new trends and points out issues in transdisciplinary temptations.

Abstract:
The recent developments in educational technologies have given opportunity to the use of various Internet-based resources, apps and Interactive Multimedia Software. This variety has provided freedom for foreign language learners to reach multiple sources of technology. The immersive nature of 3-D virtual learning environments such as the Second Life may provide many new opportunities for authentic communication, cooperative creation of content, and multiple modes of information processing in the context of foreign language learning. This chapter will discuss how these new technologies can be used in language classrooms to improve students' listening skill which is important for effective communication. In the digital age, new technologies are repositioning listening as an important ‘new' literacy where new resources can be used to provide a better learning-teaching context. Today's young people known as “digital natives” are born into a digital world, and they spend hours in front of their digital devices.

Abstract:
Abstract This paper demonstrates that an SEM stereo-pair can be accurately translated into a Digital Elevation Model (DEM) using commercial software running on a desktop computer. The DEM is easy to view without any special equipment and can provide accurate measurements of the sample in all three dimensions. Vertical height measurements with high accuracy can be obtained from the elevation model when the sample has sufficient surface texture and a uniform baseline.
