Abstract. Most commonly used detail type in 3D city modelling is building layer. One of the most important distinguishing point of buildings is independent sections. When the independent sections are examined in the context of Urban Information System (UIS), they have a multi-layered structure with their own characteristics. In address management processes, definition of the area belonging to a person, family or organization is realized through independent sections of buildings. In this study, it is aimed to model one the most important components of city objects such as building independent sections and road networks with GIS-based 3D modelling techniques. According to the results obtained from literature studies, answers were researched to the questions of what should be workflow of producing 3D models in the system and what should be in ideal 3D GIS database. Buildings and building independent sections were geocoded to provide some additional innovations to address mapping methods. Procedural modelling method was preferred as a GIS-based 3D modelling technique. Created models enable both the visualization of address data and their transfer to the 3D environment, as well as navigation. It provides some practical information. The designed system has been tested practically in Trabzon city.

Abstract Background Studying structural and functional morphology of small organisms such as monogenean, is difficult due to the lack of visualization in three dimensions. One possible way to resolve this visualization issue is to create digital 3D models which may aid researchers in studying morphology and function of the monogenean. However, the development of 3D models is a tedious procedure as one will have to repeat an entire complicated modelling process for every new target 3D shape using a comprehensive 3D modelling software. This study was designed to develop an alternative 3D modelling approach to build 3D models of monogenean anchors, which can be used to understand these morphological structures in three dimensions. This alternative 3D modelling approach is aimed to avoid repeating the tedious modelling procedure for every single target 3D model from scratch. Result An automated 3D modeling pipeline empowered by an Artificial Neural Network (ANN) was developed. This automated 3D modelling pipeline enables automated deformation of a generic 3D model of monogenean anchor into another target 3D anchor. The 3D modelling pipeline empowered by ANN has managed to automate the generation of the 8 target 3D models (representing 8 species: Dactylogyrus primaries, Pellucidhaptor merus, Dactylogyrus falcatus, Dactylogyrus vastator, Dactylogyrus pterocleidus, Dactylogyrus falciunguis, Chauhanellus auriculatum and Chauhanellus caelatus) of monogenean anchor from the respective 2D illustrations input without repeating the tedious modelling procedure. Conclusions Despite some constraints and limitation, the automated 3D modelling pipeline developed in this study has demonstrated a working idea of application of machine learning approach in a 3D modelling work. This study has not only developed an automated 3D modelling pipeline but also has demonstrated a cross-disciplinary research design that integrates machine learning into a specific domain of study such as 3D modelling of the biological structures.

In the cultural heritage field, many Serious Games applications have been developed whose goal is to educate players and users not particularly specialized or familiar with this field. On the other hand, 3D models of cultural heritage objects created with precise 3D modelling methods can be a very useful asset for these applications. In this paper a composite Serious Game for the Stoa of Attalos, a prominent monument in the Ancient Athens Agora, is developed and presented. 3D models are used, which were produced mainly with automated image based modelling techniques. The creation of the 3D models is described and presented along with the development of the application, which offers three options for the player. These options are: a quiz game, a 3D visual quiz and a virtual museum. The user interaction is described and, based on an evaluation questionnaire, the application is assessed by a group of people in the Cultural Heritage field.

Abstract. Rongorongo is an undeciphered script inscribed on wooden objects from Easter Island (Rapa Nui) in the Pacific Ocean. The existing editions of the inscriptions, and their widespread locations in museums and archives all over the world today constitute a serious obstacle to any objective paleographical assessment. Thus, with a view to a potential decipherment, creating 3D models of the available corpus is of crucial importance, and one of the objectives of the ERC INSCRIBE project, based at the University of Bologna with Professor S. Ferrara as Principal Investigator. In this preliminary work, we present the results of the 3D digitization of the Mamari tablet, one of the longest inscriptions in Rongorongo, housed in the Museum Archives of the Congregazione dei Sacri Cuori di Ges`u e Maria in Rome. The tablet is made of wood, with a shiny reflecting surface, characterized by a mainly dark texture. The 3D modelling was carried out with the ScanRider 1.2 laser scanner manufactured by VGER, based on Structured Light technology, taking care to ensure the legibility of each sign while preserving the overall shape of the object as precisely as possible. To overcome the difficulties inherent in the object’s complex fabric, the Mamari tablet was acquired in separate sections (joined together during processing through specific markers), thus managing to optimize the optical parameters of the laser scanner, such as the exposure of the camera and the depth of field of the projector. Furthermore, an evaluation of the 3D reconstruction precision was also carried out, highlighting a precision of few hundredths of millimeters, in agreement with the claimed nominal standard deviation. In addition to the 3D model produced, one of the main results of this endeavor was the definition of a successful method to scan such complex objects, which will be replicated to finalize the complete 3D modelling of the whole Rongorongo corpus of inscriptions.

AbstractObjectivesThree-dimensional (3D) reconstruction and modelling techniques based on computer vision have shown significant progress in recent years. Patient-specific models, which are derived from the imaging data set and are anatomically consistent with each other, are important for the development of knowledge and skills. The purpose of this article is to share information about three-dimensional (3D) reconstruction and modelling techniques and its importance in medical education.MethodsAs 3D printing technology develops and costs are lower, adaptation to the original model will increase, thus making models suitable for the anatomical structure and texture. 3D printing has emerged as an innovative way to help surgeons implement more complex procedures.ResultsRecent studies have shown that 3D modelling is a powerful tool for pre-operative planning, proofing, and decision-making. 3D models have excellent potential for alternative interventions and surgical training on both normal and pathological anatomy. 3D printing is an attractive, powerful and versatile technology.ConclusionsPatient-specific models can improve performance and improve learning faster, while improving the knowledge, management and confidence of trainees, whatever their area of expertise. Physical interaction with models has proven to be the key to gaining the necessary motor skills for surgical intervention.

Abstract3D modelling of man-made objects is widely used in the cultural heritage sector, among others. It is relevant for its documentation, dissemination and preservation. Related to historical fabrics, weaves and weaving techniques are still mostly represented in forms of 2D graphics and textual descriptions. However, complex geometries are difficult to represent in such forms, hindering the way this legacy is transmitted to new generations. In this paper, we present the design and implementation of SILKNOW’s Virtual Loom, an interactive tool aimed to document, preserve and represent in interactive 3D forms historical weaves and weaving techniques of silk fabrics, dating from the 15th to the 19th centuries. To that end, our tool only requires an image of a historical fabric. Departing from this image, the tool automatically subtracts the design, and allows the user to apply different weaves and weaving techniques. In its current version, the tool embeds five traditional weaving techniques, 39 weaves and six types of yarns, which have been defined thanks to close collaboration of experts in computer graphics, art history and historical fabrics. Additionally, users can change the color of yarns and produce different 3D representations for a given fabric, which are interactive in real time. In this paper, we bring the details of the design and implementation of this tool, focusing on the input data, the strategy to process images, the 3D modelling of yarns, the definition of weaves and weaving techniques and the graphical user interface. In the results section, we show some examples of image analysis in order to subtract the design of historical fabrics, and then we provide 3D representations for all the considered weaving techniques, combining different types of yarns.

The article is devoted to the problems of finding and introducing modern innovative approaches to the activities of local self-government bodies of Ukraine. It has been found that overcoming the problems of old and inefficient models and management methods that do not meet the requirements of modern communities is possible only through the development of high-quality and effective theoretical, methodical, organizational, and legal support for the process of local self-government. The definition of the concept of “local self-government” is summarized, using the regulatory margin and considering this concept in the context of modern realities, which now constantly face this institution of management. The author's interpretation of the category “local self-government” was developed for the needs of solving the problems and problems set out in the article. An organizational and legal mechanism for introducing innovative approaches to the activities of local self-government bodies has been developed as the main element of the definition of the category “local self-government.” Problems related to the effective functioning of institutions for the provision of “electronic” public services have been investigated. Innovative approaches to improving mechanisms for the provision of “electronic” public services by local authorities have been developed and justified. A general methodology for reengineering the administrative and management processes of local self-government bodies in the form of phases and stages of its implementation has been developed. It was concluded that the continuous development of the system of local self-government does not allow the development of sustainable types of innovative approaches to solve problem areas of local self-government “forever,” but requires the constant monitoring of foreign experience of advanced countries and the constant development of new and progressive innovative mechanisms that will continue to introduce decentralization reform and the creation of strong and effective local self-government bodies

The purpose of this paper is to present an investigation on the use of the term “civilization” in Muslim intellectual traditions; that is to look for the terms used in various languages used by Muslim peoples to mean civilization. It tries to find out some definition of what we mean by “civilization” as well as whatwe mean by “being civilized” in Islamic intellectual traditions. Therefore, the methodology adopted to achieve the paper's objective is to analyze the various literal and terminological words and terms used to denote civilization in various Muslim languages.The paper finds that in the Muslim scientific and cultural traditions, hadarah, tamaddun or tamadun are the various terms used. However, Ibn Khalduun’s term hadarah is the most appropriate one to express the concept of civilization in its modern sense.It is also clear that the mentioned usages of term “civilization” agree on certain rudimentary elements of civilization, that is, the presence of the city, the order or organization and the sedentary life of its inhabitants.

Competitiveness can be defined in a number of ways. We can think of it as of a successful performance of a company or organization; or we may talk about competitiveness in a macro context such as a favourable exchange rate of a national currency. Can we also talk about competitiveness of a nation? What is it and how can it be evaluated?There does not seem to be a common definition of what the international competitiveness of nations is. Some feel that the very notion of international competitiveness of nations is unfair and unacceptable. They argue that the nations themselves do not compete, their enterprises do. For others the notion of international competitiveness of nations is fair. They believe that creating appropriate measures of international competitiveness is central for tracking and understanding the sources of competitiveness of countries.In this paper I classify and compare the measures developed by various authors. I suggest that the studies on the measurement of competitiveness can be classified into five groups:1. Particular sector studies.2. Competitiveness studies at the regional / country level.3. Particular competitiveness indicator studies.4. Competitiveness studies at an international level.5. Cross-country economic policy studies.Since the competitiveness studies serve a different audience and purpose, we cannot discuss which is best without first asking: best at what?
