DOCUMENTING FOR POSTERITY: ADVOCATING THE USE OF ADVANCED RECORDING TECHNIQUES FOR DOCUMENTATION IN THE FIELD OF BUILDING ARCHAEOLOGY
Authors: De Vos P. J.
Published: August 2017

Abstract. Since the new millennium, living in historic cities has become extremely popular in the Netherlands. As a consequence, historic environments are being adapted to meet modern living standards. Houses are constantly subjected to development, restoration and renovation. Although most projects are carried out with great care and strive to preserve and respect as much historic material as possible, nevertheless a significant amount of historical fabric disappears. This puts enormous pressure on building archaeologists that struggle to rapidly and accurately capture in situ authentic material and historical evidence in the midst of construction works. In Leiden, a medieval city that flourished during the seventeenth century and that today counts over 3,000 listed monuments, a solution to the problem has been found with the implementation of advanced recording techniques. Since 2014, building archaeologists of the city council have experienced first-hand that new recording techniques, such as laser scanning and photogrammetry, have dramatically decreased time spent on site with documentation. Time they now use to uncover, analyse and interpret the recovered historical data. Nevertheless, within building archaeology education, a strong case is made for hand drawing as a method for understanding a building, emphasising the importance of close observation and physical contact with the subject. In this paper, the use of advanced recording techniques in building archaeology is being advocated, confronting traditional educational theory with practise, and research tradition with the rapid rise of new recording technologies.
PUTTING ROMAN DAMS IN CONTEXT: A VIRTUAL APPROACH

Published: August 2017

Abstract. Water resources and management have become a critical global issue. During the half-millennium of its existence, the Roman Empire developed numerous strategies to cope with water management, from large-scale urban aqueduct systems, to industrial-scale water mills designed to cope with feeding growing city populations. Roman engineers encountered, adopted, and adapted indigenous hydraulic systems, and left lasting imprints on the landscape of the Mediterranean and temperate Western Europe by employing a range of water technologies. A recent academic study has enabled the identification of remains of and references to seventy-two dams from the Roman era, constructed in Spain between the 1st and 4th century AD. Such unique heritage, without comparisons in the Mediterranean makes Spain an emblematic case study for the analysis of Roman hydraulic engineering and water management policies. Fifty dams have been located and detailed. The twenty-two outstanding, although identified on the ground, have not been able to be acceptably characterized, due in some cases to their being ruins in a highly degraded state, others due to their being masked by repairs and reconstructions subsequent to the Roman era. A good example of such neglected dams is the buttress dam of Consuegra , in Toledo province (Castilla-La Mancha). Dating to the 3rd - 4th century AD, the Dam of Consuegra, on the basin of the Guadiana, with its over 600 metres length and 4,80 metres height, is a remarkable case of Roman engineering mastery. It had a retaining wall upstream, numerous buttresses and perhaps an embankment downstream, of which no remains are left. The application of 3D digital imaging technique to create a high quality virtual model of such monuments has proved to be successful especially for the study of the technological aspects related its construction. The case study of the Roman dam of Muel (Zaragoza) has shown, in fact, as best practices in digital archaeology can provide an original and innovative perspective on a long time studied monument. In this paper it will be explored how deploying recent computer technologies to the Roman dam at Consuegra can advance our understanding of the history of local and regional landscape change and the technology of water management. In summer 2016, the dam has been documented with terrestrial laser scanning with two FARO Focus 3D x330 and aerial photogrammetry image capturing with a DJI Phantom 4 drone. Data was processed in various 3D software applications to generate 3D representations of the dam including 3D point clouds, animations, and meshed models.
PROPOSING A DIGITAL INFORMATION SYSTEM FOR THE MANAGEMENT AND CONSERVATION OF THE QHAPAQ ÑAN – ANDEAN ROAD SYSTEM
Authors: Duperré G. N.
Published: August 2017

Abstract. The ancient network of roads in the Andean region is one of the most important works of infrastructure in South America. The extensive territory where the main exchanges between their communities were locally performed is previous to the expansion of the Inca Empire. In the year 2014, the region was included on the World Heritage List by the United Nations Educational, Scientific and Cultural Organization. This communication network is the Qhapaq Ñan, Andean Road System. The Incas planned their route in the diverse landscape of the Andes to promote social and economic ties among the Andean communities. The routes originated in the central square of Cusco, creating cross-connections in a wide geographical area. The Tawantinsuyu depended on this sole route to link very distant production and worship centers. The Qhapaq Ñan was the result of a political project. Even nowadays, it continues to articulate the development of cultural traditions in the Andean region. The present contribution analyzes its transcendental importance as a Cultural Heritage and the singularity of its nomination by the UNESCO, as for the first time six countries are sharing common objectives towards guaranteeing its protection. Furthermore, this research explores the sense of timing in Latin American countries and the implicit challenges in the implementation of the new information technologies for the dissemination of information on Main Andean Road and for its conservation. Although many of the countries have already incorporated the necessary digital tools in this matter, we conclude that there is a need to implement an Integrated Digital Model for the coordinated management in the countries that form the region.
INFORMATION FLOW SETTINGS IN BUILDING REHABILITATION
Authors: Elwazani S. , Gandikota S.
Published: August 2017

Abstract. Apart from the usual field technical survey information for establishing the building configurations and fabric conditions, information flow for a rehabilitation project begins earlier with the need for authenticating the building as a significant heritage item and ends subsequently with validating the rehabilitation of the building. These three genres of the information are recognized under three information settings. This study investigates the first, the setting associated with authenticating the significance of the building. The discussion is structured around the process of evaluating building significance for the purpose of listing the building on the National Register of Historic Places (NRHP) and, accordingly, recognizes the NRHP framework for nominating properties to the Register. With due consideration to the concomitant information and documentation along the nomination process, and with the “historic context” as a core significance assessment strategy, the study aims at: a) explaining the configuration of the historic context; b) clarifying the role of the building itself in developing the historic context; and, c) identifying the attributes of information flow. The study arrived at the following conclusions. Investigating “the information associated with authenticating the significance of the building,” the focus of this study, as an information setting of a spectrum of three helps define the global information flow in building rehabilitation. Steeped in research, the historic context configuration and development steps regulate the information flow of this setting. The knowledge and dexterity of the researcher in configuring and developing the historic context enhances the clarity and characteristics of information flow.

Authors: Arif R. , Essa K.
Published: August 2017

Abstract. Lahore is an ancient, culturally rich city amidst which are embedded two world heritage sites. The state of historic preservation in the country is impoverished with a dearth of training and poor documentation skills, thus these monuments are decaying and in dire need of attention. The Aga Khan Cultural Service - Pakistan is one of the first working in heritage conservation in the country. AKCSP is currently subjecting the UNESCO World Heritage site of the Mughal era Lahore Fort to an intensive and multi-faceted architectural documentation process. This is presented here as a case study to chart the evolution of documentation techniques and enunciate the spectrum of challenges faced in the documentation of an intricate Mughal heritage site for conservation in the Pakistani context. 3D - laser scanning is used for the purpose of heritage conservation for the first time, and since has been utilised on heritage buildings and urban fabric in ongoing projects. These include Lahore Fort, Walled city of Lahore as well as the Baltit Fort, a project restored in the past, assisting in the maintenance of conserved buildings. The documentation team is currently discovering the full potential of this technology especially its use in heritage conservation simultaneously overcoming challenges faced. Moreover negotiating solutions to auto-generate 2D architectural drawings from the 3D pointcloud output. The historic architecture is juxtaposed with contemporary technology in a region where such a combination is rarely found. The goal is to continually develop the documentation methodologies whilst investigating other technologies in the future.
SMART SfM: SALINAS ARCHAEOLOGICAL MUSEUM
Authors: Inzerillo L.
Published: August 2017

Abstract. In these last years, there has been an increasing use of the Structure from Motion (SfM) techniques applied to Cultural Heritage. The accessibility of SfM software can be especially advantageous to users in non-technical fields or to those with limited resources. Thanks to SfM using, everyone can make with a digital camera a 3D model applied to an object of both Cultural Heritage, and physically Environment, and work arts, etc. One very interesting and useful application can be envisioned into museum collection digitalization. In the last years, a social experiment has been conducted involving young generation to live a social museum using their own camera to take pictures and videos. Students of university of Catania and Palermo were involved into a national event #digitalinvasion (2015-2016 editions) offering their personal contribution: they realized 3D models of the museums collection through the SfM techniques. In particular at the National Archaeological Museum Salinas in Palermo, it has been conducted an organized survey to recognize the most important part of the archaeological collection. It was a success: in both #digitalinvasion National Event 2015 and 2016 the young students of Engineering classes carried out, with Photoscan Agisoft, more than one hundred 3D models some of which realized by phone camera and some other by reflex camera and some other with compact camera too. The director of the museum has been very impressed from these results and now we are going to collaborate at a National project to use the young generation crowdsourcing to realize a semi-automated monitoring system at Salinas Archaeological Museum.
THREE-DIMENSIONAL DIGITAL DOCUMENTATION OF HERITAGE SITES USING
TERRESTRIAL LASER SCANNING AND
UNMANNED AERIAL VEHICLE PHOTOGRAMMETRY
Authors: Jo Y. H. , Kim J.Y.
Published: August 2017

Abstract. Three-dimensional digital documentation is an important technique for the maintenance and monitoring of cultural heritage sites. This study focuses on the three-dimensional digital documentation of the Magoksa Temple, Republic of Korea, using a combination of terrestrial laser scanning and unmanned aerial vehicle (UAV) photogrammetry. Terrestrial laser scanning mostly acquired the vertical geometry of the buildings. In addition, the digital orthoimage produced by UAV photogrammetry had higher horizontal data acquisition rate than that produced by terrestrial laser scanning. Thus, the scanning and UAV photogrammetry were merged by matching 20 corresponding points and an absolute coordinate system was established using seven ground control points. The final, complete threedimensional shape had perfect horizontal and vertical geometries. This study demonstrates the potential of integrating terrestrial laser scanning and UAV photogrammetry for three-dimensional digital documentation. This new technique is expected to contribute to the three-dimensional digital documentation and spatial analysis of cultural heritage sites.
BASIC VISUAL DISCIPLINES IN HERITAGE CONSERVATION:
OUTLINE OF SELECTED PERSPECTIVES IN TEACHING AND LEARNING
Authors: Lobovikov-Katz A.
Published: August 2017

Abstract. Acknowledgement of the value of a basic freehand sketch by the information and communication community of researchers and developers brought about the advanced developments for the use of sketches as free input to complicated processes of computerized visualization, so as to make them more widely accessible. However, a sharp reduction and even exclusion of this and other basic visual disciplines from education in sciences, technology, engineering and architecture dramatically reduces the number of future users of such applications. The unique needs of conservation of cultural heritage pose specific challenges as well as encourage the formulation of innovative development tasks in related areas of information and communication technologies (ICT). This paper claims that the introduction of basic visual disciplines to both communities is essential to the effectiveness of integration of heritage conservation needs and the advanced ICT development of conservation value, and beyond. It provides an insight into the challenges and advantages of introducing these subjects in a relevant educational context, presents some examples of their teaching and learning in the modern environment, including e-learning, and sketches perspectives to their application.

Published: August 2017

Abstract. Cultural heritage researchers have recently begun applying Building Information Modelling (BIM) to historic buildings. The model is comprised of intelligent objects with semantic attributes which represent the elements of a building structure and are organised within a 3D virtual environment. Case studies in Ireland are used to test and develop the suitable systems for (a) data capture/digital surveying/processing (b) developing library of architectural components and (c) mapping these architectural components onto the laser scan or digital survey to relate the intelligent virtual representation of a historic structure (HBIM). While BIM platforms have the potential to create a virtual and intelligent representation of a building, its full exploitation and use is restricted to narrow set of expert users with access to costly hardware, software and skills. The testing of open BIM approaches in particular IFCs and the use of game engine platforms is a fundamental component for developing much wider dissemination. The semantically enriched model can be transferred into a WEB based game engine platform.

Published: August 2017

Abstract. The Tin House Courtyard is a property of the National Capital Commission (NCC) in Ottawa, Canada. The site is located within the ‘Mile of History’, a historical route running from Parliament Hill to the Governor General’s residence. Currently, existing assets are under intervention works that include several preservation and renewal actions. Within the broader project, one of the tasks before construction works started was the documentation of the set of facades. The Carleton Immersive Media Studio (CIMS) at Carleton University in Ottawa was commissioned by NCC to conduct the recording of the area. This paper describes the process undertaken from field work to the final deliverable to the client, as well as the issues faced in between. Nowadays, up to date surveying technologies have revolutionized the methodologies for cultural heritage documentation. In this regard, the recording strategy employed encompassed the use of photogrammetry, laser scanner, total station, as well as different pre and post processing software in order to generate the desired outcomes.

Authors: Bitelli G. , Balletti C. , Brumana R. , Barazzetti L. , D’Urso M. G. , Rinaudo F. , Tucci G.
Published: August 2017

Abstract. GAMHer is a collaborative project that aims at exploiting and validating Geomatics algorithms, methodologies and procedures in the framework of new European regulations, which require a more extensive and productive use of digital information, as requested by the Digital Agenda for Europe as one of the seven pillars of the Europe 2020 Strategy. To this aim, GAMHer focuses on the need of a certified accuracy for surveying and monitoring projects with photogrammetry and laser scanning technologies, especially when used in a multiscale approach for landscape and built heritage documentation, conservation, and management. The approach used follows a multi-LoD (level of detail) transition that exploits GIS systems at the landscape scale, BIM technology and “point cloud based” 3d modelling for the scale of the building, and an innovative BIM/GIS integrated approach to foster innovation, promote users’ collaboration and encourage communication between users. The outcomes of GAMHer are not intended to be used only by a community of Geomatics specialists, but also by a heterogeneous user community that exploit images and laser scans in their professional activities.
The Development of Coda Consonants in the Speech of a Bilingual Child: A Case Study
Authors: Daana Hana Asaad
Published: August 2017

This paper reports on the findings of a study that explored the development of consonants in coda position in the speech of a bilingual child. This data was collected through parental diaries. The researcher traced the development of English and Arabic consonants in coda position in her own child’s production between the ages of 1.4 and 5. The analysis suggests that frequency of occurrence in the child's input plays a major role in the early appearance of particular sounds in coda position in the child's production. The analysis also reveals that the most used English consonants in coda position in the child's production are those which prefer coda position to onset position. Due to the absence of studies about the distribution of Arabic sounds within onset and coda positions, the factor that has been adopted analyzing the development of Arabic consonants in coda position is the frequency of occurrence in the child's input (parental speech). The analysis assures that the Universal Grammar Constraints also have a role in the development of some English and Arabic consonants in coda position.

Authors: Lagura Glenne Berja
Published: August 2017

The study evaluated the resources and services available in the official government websites of all the cities in Davao Region to determine the extent of its implementation of e-governance. In particular, the assessment was done to verify if the following contents were promoted in their websites: (a) citizen awareness and understanding of their community’s characteristics; (b) efficiency and effectiveness in service delivery; (c) transparency and accountability in operations and services; (d) awareness of policy making process and participation in decision making; (e) linkage and interaction between government and citizens and other groups; and (f) linkage between government and business. Moreover, the compliance of the city websites in posting the reports required by the Full Disclosure Policy (FDP) was also determined.            Results were initially obtained through an assessment done by the researcher using the checklist adapted from the study of Siar (2007). Preliminary findings were triangulated and substantiated from the Focus Group Discussion (FDG) with thirty (30) information technology participants who scrutinized the available contents in each of the website using the same checklist. Frequency counts, means and percentages were utilized from the derived significant discussions.            Findings showed that relatively low results were acquired by the city websites in Davao Region except for Davao and Tagum where most of the contents were promoted in the site. Moreover, the websites of both cities have advanced features and services which were not included in the checklist. As to the FDP compliance, findings revealed that except for Digos, all cities utilized their website to post the reports required under the FDP.            The study concludes that while all cities have utilized their websites for e-governance, the quality of its contents show substandard adoption and underutilization. The study suggests that each city exploit the benefits offered by the websites as a medium in promoting innovative public service delivery.
Managing Collaborative Innovation Networks – Practical Lessons from a Belgian Spatial Planning Initiative
Authors: Stevens Vidar , Agger Annika
Published: August 2017

Collaborative innovation networks are increasingly used as vehicles for fostering innovative policy solutions. However, scholars have noted that the extent to which collaborative networks can actually contribute to the development of innovative policy solutions depends on how they are managed. Empirical research on the management of collaborative policy innovation processes is, however, scarce. Therefore, we review in this article a case to add new insights to the causal link between collaboration, management, and innovation. Specifically, we examine the management strategies which helped a Flemish administrative network to develop a radical new Spatial Planning Policy Plan. This study shows that the best way to manage collaborative innovation networks is not to press directly for results, but take the time to invest in relationship-building and together agree on a planning and clear process steps. Such a management approach allows actors to get to know each other and from thereon expand, with more background and appreciation for the others’ goals, behaviors, and intentions, their group activities concerning the formulation of a radical and innovative policy plan.

Published: August 2017

Problemas de mobilidade urbana são correntes em na sociedade atual. Na cidade Blumenau (SC), no sul do Brasil, o tema tem ganhado atenção após aprovação da Lei Federal no. 12.587/2012, que institui a Política Nacional de Mobilidade Urbana no Brasil. Nesse meio tempo, diversos tipos de estudos e diagnósticos têm sido realizados no sentido de mensurar e propor melhorias sobre o deslocamento de bens e pessoas, como modos coletivos e não motorizados de transporte, incluindo neste caso o caminhar. Para entender a qualidade das calçadas são utilizados índices de aferição, como o Índice de Caminhabilidade (IC). O objetivo deste estudo foi identificar e mapear o IC de dois bairros de Blumenau, em Santa Catarina. Neste estudo foi utilizado um Sistema de Informação Geográfica (SIG) para espacializar o IC nos bairros estudados, que possuem deficiências no sistema de mobilidade. A pesquisa tem caráter quantitativo, do tipo explicativa e estruturou-se em três etapas: coleta de dados em campo, mapeamento das informações e análise e discussão dos resultados. A espacialização das informações foi executada com o software ArcGIS 10.3. Encontrou-se uma média superior de IC no bairro do Centro em relação ao Badenfurt, tanto em número como em extensão de trechos. A ferramenta proposta demonstrou ser adequada, podendo ser utilizada como suporte no processo de tomada de decisão relativo ao espaço geográfico.

Esta revisão bibliográfica constitui-se de um esforço teórico-metodológico, com base em discussões do trabalho de dissertação de mestrado do autor. O objetivo foi realizar uma abordagem histórico-crítica do espaço rural brasileiro do pós-Segunda Guerra Mundial, verificando momentos históricos cruciais para a configuração atual do mesmo. Para isso, partiu-se de uma análise do papel do Estado nas políticas de desenvolvimento rural da década de 1970, que culminou com a modernização da agricultura (Revolução Verde), a análise a partir da constituição de 1988, mas, sobretudo, na década de 1990, quando houve a consolidação dos movimentos e organizações sociais, a descentralização do Estado, e desregulamentação dos mercados. Assim, enfatiza-se as políticas públicas, à agricultura familiar e/ao agronegócio, comparando-as entre as duas décadas, apontando alguns dos impactos sociais ocasionados pelas transformações do espaço rural. Os principais resultados obtidos com as análises aqui apresentadas (das décadas de 1970 e 1990) indicam transformações que levam o agronegócio à hegemonia no espaço rural a partir do conteúdo da técnica, essa, seletiva e excludente. No entanto, o meio rural ficou fortemente marcado por lutas e organizações dos agricultores familiares, com objetivo de encontrar e manter seu espaço em meio à difusão do Modo de Produção Capitalista no campo.

Published: August 2017

A percepção ambiental pode ser aplicada para uma tomada de consciência e decisão sobre as ações humanas e o meio ambiente, sendo caracterizada pelo ato de perceber o ambiente, visando sua proteção e valorização. As comunidades ribeirinhas, por possuírem uma maior dependência, contato e proximidade com os recursos naturais, sofrem e percebem os impactos ambientais muito mais rapidamente do que as sociedades modernas, que não dependem diretamente dos recursos naturais para sua subsistência. Esse artigo identificou e analisou, por meio da percepção ambiental de moradores próximos do rio São Francisco, impactos socioambientais que vem ocorrendo na região de Pirapora-MG. Como instrumento de pesquisa foi utilizada a técnica de entrevistas, sendo analisadas pelo método do discurso do sujeito coletivo (DSC). Dessa forma, foram identificadas e analisadas nove distintas categorias de impactos socioambientais, baseadas nos saberes tradicionais e na compreensão das percepções ambientais sobre a água de seus moradores locais. Atualmente, devido as atuais condições dos recursos naturais, as atividades humanas devem-se integrar da melhor maneira possível com a questão ambiental, evitando novos impactos ambientais e eventos críticos que alteram a forma de vida de muitas pessoas. Considera-se também que é necessário se pensar em medidas estratégicas para o combate dos principais impactos que degradam o rio São Francisco, aprimorando a gestão para a tomada de decisão.

Authors: Ariani Dorothea Wahyu
Published: August 2017

This study applies social capital theory, motivation theory, and systems theories to examine the role of the learning environment and motivation in learning to encourage self-regulation in learning especially effort regulation. This study examines the relationship among learning environment (i.e., student cohesiveness, teacher support, involvement, investigation, task orientation, cooperation, and equity), learning motivation (i.e., learning goal orientation, task value, and self-efficacy), and self-regulated learning in effort regulation. This study also examines the mediating role of learning motivation on relation between learning environment and self-regulation in learning effort. Respondents were 307 students of undergraduate program on business, management, and economics in Yogyakarta and Bandung, Indonesia. Self-report questionnaires were administered to respondents during their regular class periods. Results revealed that students’ perception of learning environment on all dimensions were significantly related to learning motivation and self-regulation in effort regulation. Students’ perception of learning environment especially task orientation dimension was significantly influenced on three dimensions of learning motivation. The result of this study also indicated that learning goal orientation and self-efficacy are the mediating variables in the relationship model. These results supported many of the hypothesized relationships. Further explanations are discussed regarding both the expected and unexpected outcomes.
A Modelling Framework to Design Executable Logical Architecture of Engineering Systems
Authors: Abdoli Shiva , Kara Sami
Published: August 2017

Modern production, logistic and assembly systems comprise of a considerable number of processes which operate by using diverse types of resources. Conceptual design of these systems has become more complicated because of the large scale and multi-disciplinary essence of their design knowledge. This paper proposes a modelling framework to support the conceptual design of such systems. The framework employs the principles of system engineering to fulfil the necessity of having a multi-disciplinary approach for the design of such systems. The framework realizes the essence of holistic design by modelling the structural and behavioral aspects of a system in one design artefact. Object Oriented (OO) method is employed to facilitate the complexity of holistic analysis and yielding proper logics for system architecting. This paper proposes incorporating the OO analyzing semantics into Finite State Machine formalism. Therefore, the logical architecture will be established in an FSM platform. In return, the resultant artefact can stand as an executable Meta-Architecture such that design alternatives are its instances. Moreover, the Meta-Architecture enables simulation of the alternatives which serve their early validation. Accordingly, this approach opens avenues regarding incorporation of the Meta- Architecture with computational and analyzing methods which can significantly support the decision making in the conceptual design stage.

Purpose: The aim of the paper is to present the methodology of computer aided designingand manufacturing of an all-ceramic multi-unit bridge restoring missing teeth and the lostsoft and hard tissues of the oral cavity as a result of surgical treatment of oral tumor.Design/methodology/approach: The methodology of computer aided designing andmanufacturing of the multi-unit all-ceramic bridge was presented on the basis of an actualclinical case of a patient who underwent the surgical treatment of myxoma of the oral cavity.All the steps of clinical and technical production of the bridge were described and illustrated.Findings: It is possible to use the CAD/CAM technology to design and manufactureall-ceramic multi-unit bridges restoring missing teeth and the lost soft and hard tissues ofthe oral cavity. The design of the bridge must be clinically validated using mock-ups and onlythen can be implemented for the CAM software.Practical implications: Thanks to the method of designing and manufacturing of multiunitall-ceramic bridges for patients with significant lost of the soft and hard tissues of themouth it is possible to carry out a prosthetic rehabilitation of patients after trauma and tumorsurgery.Originality/value: : The execution of extensive bridges with the maximum available heightof about 25 mm requires a high technological rigor at the design and manufacture stage. Toensure longevity of the reconstruction, it is necessary to plan all the work while maintainingthe maximum thickness of the substructure. It is desirable to provide minimum of 2 mmthick substructure and the surface of at least 20 mm2 or more in the cross-sections. At thesame time, the structure of the bridge must be supported on the alveolar ridge to provideaesthetics and endurance.
Neural networks model for prediction
of the hardness of steels cooled from
the austenitizing temperature
Authors: Trzaska J.
Published: August 2017

Purpose: The paper presents the new neural networks model making it possible to estimate the hardness of continuously-cooled steel from the austenitizing temperature.Design/methodology/approach: The method proposed in the paper employs two applications of the neural networks of: classification and regression. Classification and consists in determining the value of dichotomous variables describing the occurrence of: ferrite, pearlite, bainite and martensite in the microstructure of a steel. The values of dichotomous variables have been used for calculating steel hardness. The other task is regression, which aims at calculating the steel hardness.Findings: The presented neural networks model can be used only in the range of concentrations of alloying elements shown in this paper.Practical implications: The model worked out makes it possible to calculate hardness for the steel with a known chemical composition. This model deliver important information for the rational selection of steel for those parts of the machines that are subjected to the heat treatment. The presented model make it possible the analysis of the interaction of the chemical composition on the hardness curves of the steel cooled from the austenitizing temperature.Originality/value: The paper presents the method for calculating hardness of the structural and engineering steels, depending on their chemical composition, austenitizing temperature and cooling rate.

Authors: Malara P. , Paluch K. , Sobolewska K. , Pasieka A.
Published: August 2017

Purpose: The purpose of the work was to evaluate the compressive strength of metalceramicconnections in the fixed dental restorations.Design/methodology/approach: Restorations were made on a model of the naturalpatient's dentition which was developed specifically for this study. The study included 10metal - porcelain crowns, for each group of teeth. Their production used Remanium 2000+alloy and porcelain Vita VMK Master. A static compression test was carried out on the finalcrowns and Vicker's hardness test was performed. Visual observations were carried out ona scanning electron microscope.Findings: On the basis of the research and the discussion it was possible to concludethat metal-porcelain crowns have a greater compressive strength than natural human teeth.Thus, they are more resistant to occlusal forces and the crowns for the first molars are thestrongest restorations.Practical implications: The metal-porcelain crowns are a very good option for teethrestoration and they can be used even in the areas of the mouth where the occlusal forcesreach the maximum values.Originality/value: The article focuses on testing of compressive strength of metal-ceramiccrowns. The comparison with natural human occlusal forces shows the sufficient mechanicalproperties of metal-ceramic crowns for application in humans. The artificial tooth geometryallows applying prosthetic crowns in the patient's mouth without the risk of ceramic breakdown.

Published: August 2017

Purpose: of this paper was to develop and to characterize the mechanical behaviour
of a structural composite obtained from a bio-based polyurethane matrix reinforced with
fiberglass.
Design/methodology/approach: Castor oil and Kraft lignin-containing polyol was
applied for bio-based polyurethane synthesis. Structural composite was obtained by
reinforcing this renewable source bio-based polymer with fiberglass mat. Polyester
resin composite was also obtained for comparison, following the same process and
reinforcement conditions. Mechanical characterization was carried out through uniaxial
tensile, flexural strength, Izod impact tests and additionally scanning electron microscopy
(MEV).
Findings: Bio-based polyurethane composite was obtained and presented higher ultimate
tensile strength (UTS) and equivalent impact resistance in comparison to polyester matrix
composite.
Research limitations/implications: Effects of Kraft lignin and fiberglass contents
changing on mechanical properties might be investigated in future researches.
Practical implications: Revalorization of Kraft lignin. 50 million tons of lignin are produced
worldwide every year as by-product of pulp and paper manufacturing. The most part of this
Kraft lignin is currently burned for energy generation.
Originality/value: Results indicated the possibility of reusing this industrial wasted
by-product at large scale as polymeric matrix for structural composite, in which high UTS
and impact resistance are required.
Modelling of superplastic deformation
for metallic alloys using a cavity based
approach
Authors: Hedayati Marzbali M.
Published: August 2017

Purpose: In this study, modeling of superplastic deformation characteristic for metallic
alloys was investigated using GTN failure criteria in viscoplastic framework.
Design/methodology/approach: The proposed model studied the simultaneous
effects of cavitation and deformation parameter and considered the effects of strain
hardening, static and dynamic recoveries, and hydrostatic stress. This cavity based model
was then implemented in a creep subroutine in ABAQUS 6.12 finite element software.
Findings: Experimental results of Aluminum 5083 from different studies were used to verify
the model and evaluate its reliability. Afterwards, numerical simulations for uniaxial tension
were performed, and good agreement between experimental and modeling results was
obtained.
Research limitations/implications: This study showed that using a viscoplastic
framework with a cavity criterion ensures more precise pressure-time algorithm, lower
deformation time and better failure predictions. These capabilities provides forming more
complex parts and different geometries. Accordingly, applying this model is recommended
to predict the behaviour of other metallic superplastic alloys.
