Nearby objects distort the flow field created by the motion of the fish. These flow distortions are sensed by the mechanosensory lateral line. Little is known about the fluid mechanics involved in hydrodynamic imaging, or how the behaviour of the fish might influence their ability to sense the world around them. Automated image analysis was used to study the effects of swimming kinematics on the ability of the fish to sense their surroundings when introduced into a novel environment. The fish reacted to avoid head-on collisions with a wall at a remarkably short mean distance of 4.0 ± 0.2 mm. The ability of the fish to react, was dependent on whether they were beating their tail as they approached the wall. When following surfaces, such as a wall, the fish changed their swimming kinematics significantly and used both tactile and hydrodynamic information. Measuring the tendency of the fish to follow a tightening curve showed the fish to be moderately thigmotactic. The flow fields around freely swimming fish were experimentally measured using Particle Image Velocimetry (PIV). A new algorithm was developed to calculate the pressure field around the fish based on the velocity field measured using PIV. The algorithm was validated against analytical and computational fluid dynamic (CFD) solutions. The flow fields around gliding fish and the stimuli to the lateral line of the fish were calculated using CFD models, validated against the experimental PIV data. The flow fields changed in characteristic ways as the fish approached a wall head-on or swam parallel to a wall. At 0.10 body lengths from a wall, the stimulus to the lateral line was estimated to be sufficient for the fish to be able to detect the wall, but this decreased rapidly with increasing distance from the wall. The CFD models suggested that the velocity of the fish does not affect the distance at which they detect an object. Hydrodynamic imaging is a short range sensory ability and blind cave fish require their sensitive lateral line and fast reactions in order to be able to use it to sense the world around them and avoid collisions. The information gained about the fluid mechanics of hydrodynamic imaging, and the flow measurement and modelling techniques developed here will be useful for further study of this remarkable ability.

Η παρούσα πτυχιακή εργασία εστιάζει κυρίως στην ανάδειξη της συμβολής της γεωφυσικής διασκόπησης, στον εντοπισμό υπεδαφικών αρχαιολογικών υπολειμμάτων. Η εργασία αυτή αποτελεί τον καρπό της συνεργασίας του Εργαστηρίου Γεωφυσικής του Πανεπιστημίου Πατρών, με το Τμήμα Αρχαιολογίας του Πανεπιστημίου Αθηνών. Σκοπός ήταν η ανεύρεση ενδεικτικών στοιχείων από ανθρωπογενή παρέμβαση σε περιοχή του Λόφου του Υμηττού και ειδικότερα εντός σπηλαίου όπου εντοπίζεται στην παρειά αυτού και είναι γνωστό με την ονομασία Λεοντάρι. Με γνώμονα υπάρχουσες μαρτυρίες των Αρχαίων συγγραφέων, τις υποδείξεις της υπεύθυνης αρχαιολόγου κ. Λ. Καραλή, Καθηγήτριας στο Τμήμα Αρχαιολογίας, σε συνδυασμό με το επικρατών γεωλογικό καθεστώς αναπτύχθηκε ανάλογη μεθοδολογία για την εφαρμογή της γεωφυσικής διασκόπησης. Εφαρμόστηκε συνδυασμός δύο διαφορετικών γεωφυσικών τεχνικών. Η πρώτη αποσκοπούσε στην καταγραφή του μέτρου της ολικής έντασης του γεωμαγνητικού πεδίου, με την βοήθεια ειδικών συσκευών, γνωστών ως πρωτονιακά μαγνητόμετρα. Ως δεύτερη τεχνική επιλέχτηκε η κατακόρυφη ηλεκτρική τομογραφία, που αποσκοπούσε στην καταγραφή της ειδικής ηλεκτρικής αντίστασης σε συνάρτηση με το βάθος. Η εφαρμογή των ανωτέρων τεχνικών πραγματοποιήθηκε επί νοητών ευθειών γνωστών και ως διατομές. Κατά την διάρκεια των μετρήσεων λήφθηκε υπόψη και το τοπογραφικό ανάγλυφο του σπηλαίου που χαρακτηρίζεται γενικά από εξάρσεις και μεγάλη κλίση. Μέσω ειδικών λογισμικών επιτεύχθηκε η επεξεργασία των ήδη καταγεγραμμένων μετρήσεων και παράχθηκαν έγχρωμοι χάρτες που απεικόνιζαν την κατανομή του μετρούμενου γεωφυσικού μεγέθους. Εν συνεχεία με χρήση ειδικών πινάκων από την διεθνή βιβλιογραφία, επιχειρήθηκε η αποκρυπτογράφηση των εμφανιζόμενων γεωφυσικών ανωμαλιών, με στόχο την υπόδειξη ύπαρξης πιθανών αρχαιολογικών ευρημάτων. / This thesis is referred to the contribution of geophysical techniques in order to solve a difficult archaeological problem. The project was a collaboration between Laboratory of Geophysics from University of Patras and Department of Archaeology from University of Athens. Prof Karali requested from our Laboratory to investigate a cave which is located on Ymitos Hill at Athens, for the detection of possible buried archaeological remains. According to Ancient writers, this cave was used from ancient people as main home and the archaeologist believed that perhaps there were evidence from human activity. Our Laboratory accepted the request to participate in this research and begun to plan the schedule of the geophysical investigation, while there was the experience of such kinds of investigations from previous surveys. A systematic geophysical research applied inside the cave, by using two different geophysical techniques. Firstly a detailed geomagnetic survey took place, by recording the distribution of total geomagnetic intensity in nTesla. By using two proton magnetometers type Elsec 820, a detailed geophysical research applied, by measuring stations with interval equal to one meter. The geomagnetic survey applied not only on unique profile but also and on well predefined geophysical grid. As second technique applied the vertical geoelectric imaging by adopting Wenner, Dipole-Dipole & Wenner-Schlumberger electrode arrangement. The space of electrodes was varying between 0.5-1.4 m distance in order deeper possible structures to be recorded. As main objective of that technique was the distribution of resistivity according to the depth. After the research in field, the geophysical data were processed through special geophysical software, where as result was the creation of coloured scale maps with the distribution of measured geophysical property.

This interdisciplinary thesis is about dwelling, both as a method in archaeology and as a mode of existence. My thesis has two principal aims. Firstly, to explore the 'dwelling perspective' as this has been outlined in recent archaeological theory. This will involve discussion of phenomenological philosophy and the figure of Martin Heidegger. The term 'dwelling' is a technical one originating in Heidegger's philosophy of being. Phenomenology has been making inroads into archaeological theory as a consequence of the interpretive turn of the 1980s. The theoretical commitment of this thesis is that phenomenological inquiry is a useful project in archaeological research. Reflexive archaeological research in the present might articulate and confirm certain phenomenological dimensions of present experience so as to inform and enhance our understanding of the past. Secondly, I discuss the notion of dwelling in the existential sense as a mode of existence in terms that might allow us to deploy this concept in Palaeolithic archaeology, with specific reference to mortuary practice and "art". I propose two case studies in order to explore this. Firstly, mortuary practice and existential awareness of death will be explored with reference to the site of the Sima de los Huesos. Secondly, Heidegger's notion of artistic production as a world-opening event will be explored in relation to Upper Palaeolithic art in caves. The focus on mortuary practice and art is not arbitrary: both are central planks of Heidegger's account of dwelling and both are linked by 'heterotopic' space. Heidegger presented a novel account of human existence as 'Dasein'. Dasein is being-in-the-world and being-in-the-world is unified by what Heidegger called 'care' (Sorge). Heidegger's account of Dasein remains anthropocentric: I argue that we should move away from Heidegger's own anthropocentric view of being-in-the-world, dwelling or care toward a phenomenological archaeology that goes 'beyond the human'. I argue that care or dwelling is evidenced by the archaeological record of human becoming and that our ancestors 'cared for' or 'dwelled with' their dead. Care is evidenced by appropriating the world and by looking after compatriots within the world, and I argue that such an existential state had been reached before the advent of the Upper Palaeolithic. I argue that Upper Palaeolithic "art" opened up a hunter-gatherer world that enabled others, including animal others, and objects, to become meaningful to groups of Daseins, and so to become part of particular "dwelling places". Heidegger remains the key theorist of dwelling but his anthropocentrism should be abandoned. Suitably revised, Heidegger's account of dwelling will provoke us to look at Palaeolithic archaeology from a fresh perspective.
