Heraklion-Chania: a study of its spatial and functional patterns
No full textThis thesis is a comparable approach to the evolution of spatial and functional patterns of two Cretan cities: Heraklion and Chania. The starting point of this research is the different functional patterns of their contemporary old historial cores. This thesis aims at investigating the reasons that led to this difference. The research is based on the conjecture that it is the morphology of their grid that differs and this aspect is reflected on their different functional pattern. The analytical method employed is 'space syntax'. Through this spatio-analytical method the research investigates the spatial organisation of these two Cretan cities in their stages of development and the evolution of their functional patterns. The study is based on the concept of 'live centrality' as a spatio-functional process, which every urban system reinforces. In the light of this theoretical framework and through its analytical methodology this thesis explores the relation between the spatial and functional patterns of both cities
Regaining public space in modern Greece: The case of Chania
No full textTaking into consideration that ancient Greece is highly correlated to the democratic public space, the aim of the present thesis is to regain public space in modern Greece, by having as a testing location a medium-sized city, Chania. Public space was an important part of Greek people’s lives in the different chronological periods of its history. Starting from antiquity, the ancient agora and the Greek polis were considered as prototypes of democratic public spaces. In more modern years though, the relationship between Greek people and public space was gradually lost, leading to the present-day function of the Greek public spaces. Nowadays, most Greek people spend their free time in cafeterias and bars, neglecting so public spaces, such as squares, parks etc. Even though it is undeniable that cafeterias play an important role in the sociability, liveability and the economic vitality of an area, the way they function in Greece leads to the extreme privatization of public space due to coffee tables, the absence of people in areas where there are no cafes or the occupation of the empty public spaces by marginalized groups. Hence, the present thesis is dealing with the problematic use and the poor quality of public space in the Greek context, and especially in the city of Chania, as a case study. Many of the public spaces are extreme privatized, causing problems of accessibility and walkability, while others are not used at all or used by specific social groups developing urban voids or ghettos in the city. This existing defective Greek reality results in social exclusion and poor social interaction among different demographics, questioning the serving of needs of the different users. Taking into consideration the above-mentioned problem statement and the results by the different research methods used, it is concluded that the enhancement of sense of security, social interaction and inclusion are the main goals to be achieved in the project. Since these three concepts are more social than spatial related, design patterns are used as a method for their translation into space and urban environment. Moreover, they function as a bridge between research and design. In the end, to avoid generic solutions the definition of the patterns is a forth and backwards procedure between research and design
Slope deformation, reservoir variation and meteorological data at the Khoko landslide, Enguri hydroelectric basin (Georgia), during 2016–2019
No full textThe Greater Caucasus mountain belt is characterized by deep valleys, steep
slopes and frequent seismic activity, the combination of which results in
major landslide hazard. Along the eastern side of the Enguri water reservoir
lies the active Khoko landslide, whose head scarp zone affects the important
Jvari–Khaishi–Mestia road, one of the few connections with the interior of
the Greater Caucasus. Here, we present a database of measurement time series
taken over a period of 4 years (2016–2019) that enables us to compare slope
deformation with meteorological factors and human-induced perturbations owing
to variations in the water level of the reservoir. The monitoring system we
used is composed of two digital extensometers, placed within two artificial
trenches excavated across the landslide head scarp. The stations are
also equipped with internal and near-ground surface thermometers. The dataset is integrated by daily measurements of rainfall and lake level. The
monitoring system – the first installed in Georgia – was set up in the
framework of a NATO-funded project, aimed at assessing different types of
geohazards affecting the Enguri artificial reservoir and the related
hydroelectrical plant. Our results indicate that the Khoko landslide
displacements appear to be mainly controlled by variations in hydraulic
load, in turn induced by lake level oscillations. Rainfall variations might
also have contributed, though this is not always evident for all the studied
period. The full databases are freely available online at the following DOI:

Une isoglosse onomastique péloponnésienne en Crète occidentale au IIe millénaire av. J. C. : les toponymes en °e-wa (°εα / °εη) et l’anthroponyme ko-ne-wa-ta à Chania
No full textInternational audienceThis study proposes that the personal name konewata, documented in two Linear B tablets from Pylos and Chania, can be plausibly traced back to an unattested place name *Skhoinē̆u̯ā. The distinctive toponymic ending °ē̆u̯ā, which is conspicuously absent in place names found in Cnossian texts, suggests an onomastic influence originating from the Peloponnese that extended to the west of Crete by the end of the 2nd millennium BCE.Cette étude propose que le nom personnel konewata, attesté dans deux tablettes en linéaire B de Pylos et de Chania, est vraisemblablement rattaché à un toponyme non attesté, *Skhoinē̆u̯ā. La terminaison toponymique particulière °ē̆u̯ā, remarquablement absente des toponymes dans les textes de Cnossos, suggère une influence onomastique provenant du Péloponnèse et ayant atteint l’ouest de la Crète à la fin du IIe millénaire av.

ESTIMATION OF SEISMIC RESPONSE OF HISTORICAL AND MONUMENTAL SITES USING MICROTREMORS: A CASE STUDY IN THE ANCIENT APTERA, CHANIA, (GREECE)
No full textMain purpose of the present study is to investigate the dynamic characteristics of the remainings at the ancient city of Aptera (Chania) and identify the main damage mechanism, in order to evaluate the risk of structure damage or collapse in case of future events using microtremor recordings. Our study focuses on the application of HVSR method (Horizontal to Vertical Spectral Ratio) to microtremor measurements carried out in specific sites. Registrations have been performed by means of a tridirectional sensor Lennartz 3D-Lite (1 natural Hz frequency), connected with a 24-bit digital acquisition unit. A set of 10 time series of 800 second each, sampled at 125 Hz was recorded in several sites. The selected time windows of each time series were corrected for the base line and for anomalous trends, tapered with a cosine function to the first and last 5% of the signal, and band pass filtered from 0.5 to 20 Hz with cut off frequencies at 0.3 and 22 Hz. The same procedure performed for all sites and components and finally the H/V spectral ratios were computed. Most of the sites present significant amplification peaks in frequency around 2 Hz. Finally, electrical resistivity tomography was carried out. The extracted results clearly show a very complex subsurface geometry indicated by the presence of large-scale voids, which may possibly correspond to ancient reservoirs. In the present work we confirm that the archaeological site of Aptera in Chania consists of a very complex subsurface structure and that the results obtained by HVSR method and by resistivity method are very well correlated

Properties of the geoelectric structure that promote the detectionof electrotelluric anomalies: the case of Ioannina, Greece
No full textThe reliable detection and identification of electrotelluric anomalies that could be considered as precursory phenomena of earthquakes become fundamental aspects of earthquake prediction research. Special arrangements, in local and/or regional scale, of the geoelectric structure beneath the measuring point, may act as natural real-time "filters" on the ULF electrotelluric data improving considerably the signal to "magnetotelluric-noise" ratio of anomalies originated by probably non-magnetotelluric sources. Linear polarization, i.e. local channelling of the electric field on the surface is expected in cases where 3D-local inhomogeneities, producing strong shear distortion, are present in the vicinity of the monitoring site and/or when a 2D-regional geoelectrical setting exhibits high anisotropy. By assuming different generation mechanisms and modes of propagation for the electrotelluric anomalies that could be considered earthquake precursory phenomena, a rotationally originated residual electrotelluric field results, eliminating background magnetotelluric-noise and revealing "hidden" transient variations that could be associated to earthquakes. The suggested method is applicable in real-time data collection, thus simplifies and accelerates the tedious task of identification of suspicious signals. As an indicative example, the case of Ioannina (located in Northwestern Greece) is presented. The local polarization of the electrotelluric field varies dramatically even at neighboring points although the regional geoelectric strike direction does not change.+JCR Journalope
