Öğe 3D MODELING OF THE ARCHAIC AMPHORAS OF IONIA(Copernicus Gesellschaft Mbh, 2015) Denker, A.; Oniz, H.Few other regions offer such a rich collection of amphoras than the cities of Ionia. Throughout history amphoras of these cities had been spread all over the Mediterranean. Despite their common characteristics, amphora manufacturing cities of Ionia had their own distinctive styles that can be identified. They differed in details of shape and decoration. Each city produced an authentic type of amphora which served as a trademark of itself and enabled its attribution to where it originated from. That's why, amphoras provide important insight into commerce of old ages and yield evidence into ancient sailing routes. Owing to this our knowledge of the ancient trade is profoundly enriched. The following is based on the finds of amphoras which originated from the Ionian cities of Chios, Clazomenai, Lesbos, Miletus, and Samos. Starting from city-specific forms which offer interpretative advantages in provenancing, this article surveys the salient features of the regional forms and styles of the those Ionian cities. 3D modeling is utilized with the aim of bringing fresh glimpses of the investigated amphoras by showing how they originally looked. Due to their virtual indestructibility these models offer interpretative advantages by enabling experimental testing of hypotheses upon the finds without risking them. The 3D models in the following sections were reconstructed from numerous fragments of necks, handles, body sherds and bases. They convey in color-unlike the monochrome drawings which we were accustomed to-the texture, decoration, tint and the vitality of the amphoras of Ionia.Öğe Ancient shipyard on Turkey's Dana Island: Its 3D modelling with photogrammetry and computer graphics(International Society for Photogrammetry and Remote Sensing, 2018) Denker, A.; Oniz, H.Although a small island 2 km off the southern coast of Turkey, Dana Island offers a rich history which is likely to shed light upon the Dark Ages. Starting from 2015 our archaeological team discovered through continuing coastal and underwater excavations 274 shipsheds/slipways there. This discovery places Dana Island among the biggest shipyards of antiquity. The slipways varied in dimensions suitable for vessels of different sizes from small boats to large warships. Historical sources suggest that the name of the island may stem from Yadnana, Yadana or Adana which was mentioned in an Assyrian tablet of the 8th century BC, as an island in the vicinity of Cyprus. Archaeological evidence exists that shows Dana Island had played a significant role in seamanship activities in Levant starting from Neolithic times. A substantial part of the naval campaigns must have involved Dana Island which used be the biggest shipyard/naval base of the Eastern Mediterranean. A 3D model of the island has been made by using photogrammetry and computer graphics methods and simulations were executed to check the hypotheses related to the involvement of Dana Island in the major sea battles of antiquity, such as Sea Battle of Lade in 495 BC. © Authors 2018.Öğe Design and implementation of a semi-autonomous mobile search and rescue robot: SALVOR(Institute of Electrical and Electronics Engineers Inc., 2017) Denker, A.; Işeri, M.C.Humankind encounters with unprecedented number and scales of disasters which stem from natural and human-made causes. So many victims have suffered severely in those catastrophes that compelled generation and development of search and rescue technology to help victims in future. One of the most important application areas within this scope is the search and rescue robots. The robots equipped with capabilities of sensing and maneuvering in the areas of calamity are enticing more and more attentions from researchers and rescuers. This project aims at realization of a new generation of search and rescue robot which can work in autonomous and semi-autonomous modes and can be used in harsh physical environments of disaster regions to carry out the given tasks more effectively by the use of advanced and economic sensors. In this paper, a mobile search and rescue robot called SALVOR is designed and implemented. SALVOR partly relies on the data from its sensors about the environment and partly on instructions from the human operators for its operation. On the other hand it provides information about its surroundings for situation assessment. Design and implementation processes of SALVOR are described and its test results are presented in an arena which simulates the calamity zone. © 2017 IEEE.Öğe Palmyra in Context: An Intelligent Reality Application to Revive the Victimized Bride of the Desert*(IEEE Computer Soc, 2022) Denker, A.Symbolic buildings and cities have long been targeted and still are being targeted raising the importance of safeguarding the world's architectural heritage record, and our cultural memory. This article looks at a series of actions aimed at devastating historic cities and cultural heritage, and examines 3D visualization with Intelligent Reality as a new way to post-trauma reconstruction. The method of modeling and reconstructing the lost heritage is demonstrated with an application to Palmyra.Öğe Protection of privacy and personal data in the big data environment of smart cities(International Society for Photogrammetry and Remote Sensing, 2021) Denker, A.The project of smart cities has emerged as a response to the challenges of twenty-first-century urbanization. Solutions to the fundamental conundrum of cities revolving around efficiency, convenience and security keep being sought by leveraging technology. Notwithstanding all the conveniences furnished by a smart city to all the citizens, privacy of a citizen is intertwined with the benefits of a smart city. The development processes which overlook privacy and security issues have left many of the smart city applications vulnerable to non-conventional security threats and susceptible to numerous privacy and personal data spillage risks. Among the challenges the smart city initiatives encounter, the emergence of the smartphone-big data-The cloud coalescence is perhaps the greatest, from the viewpoint of privacy and personal data protection. As our cities are getting digitalized, information comprising citizens' behavior, choices, and mobility, as well as their personal assets are shared over smartphone-big data-The cloud coalescences, thereby expanding cyber-Threat surface and creating different security concerns. This coalescence refers to the practices of creating and analyzing vast sets of data, which comprise personal information. In this paper, the protection of privacy and personal data issues in the big data environment of smart cities are viewed through bifocal lenses, focusing on social and technical aspects. The protection of personal data and privacy in smart city enterprises is treated as a socio-Technological operation where various actors and factors undertake different tasks. The article concludes by calling for novel developments, conceptual and practical changes both in technological and social realms. © Author(s) 2021.

These were the fruits of the great temple-building epoch that began with the building of the Great Temple of Hera at Samos in the first half of the 6th century B.C. This period had passed by the end of the 5th century B.C; but the recurrence of destruction, of fires caused by arsonists, rioters and invaders required the reconstruction of these structures. In this paper, the history of their construction, reconstruction and destruction are related. The exceptional architects who had defined and clarified the style and the principles of construction, together with the superstructures they created are studied from the accounts by ancient writers, fragments in museums and the surviving insitu evidence. Finally, their 3D reconstructions are realized so far as is been possible. © Archaeopress and the individual authors 2018.

The temples were the epitome of elegance and splendour, difficult to surpass in terms of architectural achievement for a period of four centuries from 6th century to 2nd century BC which spans Archaic, Classical and Hellenistic eras. All of these edifices now lie in ruins. As various empires in the region rose and fell, the temples suffered looting and destruction. Nature also played a part with rivers inundating the temenoses and silting up the archaeological remains, and earthquakes toppling columns and reducing the cellas to rubble. Despite this catacylism, tens of hundreds of years after they were built, these marble buildings still tantalise the human imagination. The objective of this paper is to present a systematic and comprehensive treatise of the logical procedure of the 3D visualisation of these monuments of the ancient cities of classical antiquity. The virtual rediscovery and visual recovery can never replace or remedy the loss of the temples. It can, however, visually awaken the imagination and provide a hypothesised experience of the temples as well as restoring a sense of the architecture and the place.Öğe Reviving the temple of Athena Ilias at Troy/Ilion(Elsevier Ltd, 2023) Denker, A.Owing to the legendary fame of Troy's story, the Temple of Athena (the Athenaion) is one of the most enigmatic monuments of antiquity which holds an influential mythical legacy. Long after the great days of Homer's Troy, a new Hellenistic city called Ilion (Roman = Ilium) was founded on the site. At Ilion a new custom that solidified the Homeric credentials of the site was established, and a new temple was built to Athena. Since the temple was almost completely decimated and even its remains were demolished during excavations, it has been one of the most difficult Hellenistic temples to reconstruct. A virtual revival of the non-existing superstructure is presented in this work by synthesizing the existing knowledge (e.g. literary evidence, archaeological evidence, numismatic evidence, topographical evidence, etc.) to support a realistic reconstruction. Along with the immersive visualizations offered by digital technologies, a virtual 3D visit to the sanctuary of the Temple of Athena offers a very attractive opportunity to examine this temple or experience its cultural space. The realistic reconstruction of the Athenaion is important in reviving the Homeric associations of the site and refreshing the memory. © 2023 Elsevier LtdÖğe RoboSantral An autonomous mobile guide robot(IEEE, 2015) Denker, A.; Dilek, A.
