Tsleil-Waututh health, sickness, disease and treatment: an exploratory ethnography
Creators: name: Thunderchild, Marlene C. (Boissoneau)
Publisher: name: University of British Columbia
Year: 2009

description: The theologically based healing practices of Canadian First Nations people has begun to receive attention from a variety of people: scientists, therapists, health care practitioners, ecologists and academics. This apparent wholistic ideology is considered to be a forerunner to health care maintenance and preventative therapeutic interventions in terms of the process of healing amongst certain groups in Canada. Nonetheless, Status Indian people in Canada continue to experience greater rates of disease, mortality, and social ills than the average Canadian citizen. This research project focusing on the Tsleil-Waututh First Nation citizens involves experiences with sickness, disease, health and treatment. It observes and translates the peoples' health care experiences beginning with experiences of historical relationships within their contexts, the influence of religion, the evolution of those relationships, and the decisions that influence health care choices both past and present. This study is relevant to social work because it provides a community specific example of culturally interpreted explanations of health care practices and experiences both past and present.

Improved Constraints on the Initial-to-Final Mass Relation of White Dwarfs using Wide Binaries

description: We present observational constraints for the initial-to-final mass relation (IFMR) derived from 11 white dwarfs (WDs) in wide binaries (WBs) that contain a turnoff/subgiant primary. Because the components of WBs are coeval to a good approximation, the age of the WD progenitor can be determined from the study of its wide companion. However, previous works that used WBs to constrain the IFMR suffered from large uncertainties in the initial masses because their MS primaries are difficult to age-date with good precision. Our selection of WBs with slightly evolved primaries avoids this problem by restricting to a region of parameter space where isochrone ages are significantly easier to determine with precision. The WDs of two of our originally selected binaries were found to be close double degenerates, and are not used in the IFMR analysis. We obtained more precise constraints than existing ones in the mass range 1-2 M$_{\odot}$, corresponding to a previously poorly constrained region of the IFMR. Having introduced the use of turnoff/subgiant-WD binaries, the study of the IFMR is not limited anymore by the precision in initial mass, but now the pressure is on final mass, i.e., the mass of the WD today. Looking at the full dataset, our results would suggest a relatively large dispersion in the IFMR at low initial masses. More precise determinations of the mass of the WD components of our targets are necessary for settling this question.

description: Context: Accretion onto galactic and supermassive black holes occurs in different modes, which are documented in hard and soft spectral states, commonly attributed to an advection-dominated flow (ADAF) inside a truncated disk and standard disk accretion, respectively. At the times of spectral transition an intermediate state is observed, for which the accretion flow pattern is still unclear. Aims: We analyze the geometry of the accretion flow when the mass flow rate in the disk decreases (soft/hard transition) and evaporation of gas into the coronal flow leads to disk truncation. Methods: We evaluate the physics of an advection-dominated flow affected by thermal conduction to a cool accretion disk underneath. We find re-condensation of gas from the ADAF into the underlying inner disk at distances from the black hole and at rates, that depend on the properties of the hot ADAF and vary with the mass accretion rate. This sustains an inner disk for longer than a viscous decay time after the spectral transition occurred, in accordance with the spectra that indicate cool gas in the neighborhood of the accreting black hole. The model allows us to understand why Cyg X-1 does not show hysteresis in the spectral state transition luminosity that is commonly observed for X-ray transient sources. Conclusions: Our results shed new light on the complex mass flow pattern during spectral state transition.

Αρχικά εξετάζεται η έννοια του εθελοντισμού και τα χαρακτηριστικά του, οι αρχές της εθελοντικής προσφοράς και τα χαρακτηριστικά των σύγχρονων εθελοντών. Στη συνέχεια παρουσιάζονται οι διάφορες μορφές του εθελοντισμού επικεντρώνοντας κυρίως στις εθελοντικές οργανώσεις του Τομέα Υγείας, στον Ερυθρό Σταυρό, στους οργανισμούς προστασίας των παιδιών και της προστασίας του περιβάλλοντος. Ακόμη γίνεται μια ιστορική αναδρομή του φαινομένου στον ελλαδικό χώρο από την Αρχαιότητα, το Βυζάντιο και την Τουρκοκρατία μέχρι και τη σύγχρονη εποχή. Ένα άλλο θέμα που εξετάζεται είναι η διάκριση μεταξύ εθελοντισμού και φιλανθρωπίας. Μας απασχόλησε ακόμη η έννοια του εθελοντισμού τόσο στην Παλαιά όσο και στην Καινή Διαθήκη, η θέση των Πατέρων της Εκκλησίας πάνω στο θέμα της προσφοράς αλλά και το φιλανθρωπικό έργο της Εκκλησίας. Ασχοληθήκαμε επίσης με τα οφέλη του εθελοντισμού αλλά και τα κίνητρα των εθελοντών, τα οποία σε ορισμένες περιπτώσεις μπορεί να είναι και ιδιοτελή.

description: The purpose of the present master thesis is the ethical consideration of volunteering. The thesis puts to the fore the concept of volunteering and its characteristics, the principles of volunteering and the characteristics of the modern volunteers. In addition, the study highlights the various forms of the volunteerism, focusing mainly on voluntary organizations of the Health Sector, on the Red Cross, on child protection organizations and on environment protection organizations. Furthermore, special focus is given on a throwback in Greece from the Antiquity, the period of Byzantine and Ottoman Empire to modern times. Another topic examined is the distinction between volunteering and philanthropy. The study also investigates the conception of volunteering in both the Old and New Testament, the position of the Church Fathers on the subject of the offer and the charitable mission of the Church. Another aim of this study is to examine the benefits of volunteering and the motivations of volunteers, which in some cases can be self-interested as well. Finally, the preconditions are needed, in order the citizens to become active, are analyzed extensively.

description: We consider thermal relaxation process of a quantum system attached to a single or multiple reservoirs. Quantifying the degree of irreversibility by entropy production, we prove that the irreversibility of the thermal relaxation is lower-bounded by a relative entropy between the unitarily-evolved state and the final state. The bound characterizes the state discrepancy induced by the non-unitary dynamics, thus reflecting the dissipative nature of irreversibility. Intriguingly, the bound can be evaluated solely in terms of the initial and final states and the system Hamiltonian; hence, providing a feasible way to estimate entropy production without prior knowledge of the underlying coupling structure. Our finding refines the second law of thermodynamics and reveals a universal feature of thermal relaxation processes.

description: Although there is general agreement that a removal of classical gravitational singularities is not only a crucial conceptual test of any approach to quantum gravity but also a prerequisite for any fundamental theory, the precise criteria for non-singular behavior are often unclear or controversial. Often, only special types of singularities such as the curvature singularities found in isotropic cosmological models are discussed and it is far from clear what this implies for the very general singularities that arise according to the singularity theorems of general relativity. In these lectures we present an overview of the current status of singularities in classical and quantum gravity, starting with a review and interpretation of the classical singularity theorems. This suggests possible routes for quantum gravity to evade the devastating conclusion of the theorems by different means, including modified dynamics or modified geometrical structures underlying quantum gravity. The latter is most clearly present in canonical quantizations which are discussed in more detail. Finally, the results are used to propose a general scheme of singularity removal, quantum hyperbolicity, to show cases where it is realized and to derive intuitive semiclassical pictures of cosmological bounces.

description: In April-May 2003, the blazar 1ES 1959+650 showed an increased level of X-ray activity. This prompted a multiwavelength observation campaign with the Whipple 10 m gamma-ray telescope, the Rossi X-ray Timing Explorer, the Bordeaux Optical Observatory, and the University of Michigan Radio Astrophysical Observatory. We present the multiwavelength data taken from May 2, 2003 to June 7, 2003 and compare the source characteristics with those measured during observations taken during the years 2000 and 2002. The X-ray observations gave a data set with high signal-to-noise light curves and energy spectra; however, the gamma-ray observations did not reveal a major TeV gamma-ray flare. Furthermore, we find that the radio and optical fluxes do not show statistically significant deviations from those measured during the 2002 flaring periods. While the X-ray flux and X-ray photon index appear correlated during subsequent observations, the apparent correlation evolved significantly between the years 2000, 2002, and 2003. We discuss the implications of this finding for the mechanism that causes the flaring activity.

description: We have measured noise in thin-film superconducting coplanar waveguide resonators. This noise appears entirely as phase noise, equivalent to a jitter of the resonance frequency. In contrast, amplitude fluctuations are not observed at the sensitivity of our measurement. The ratio between the noise power in the phase and amplitude directions is large, in excess of 30 dB. These results have important implications for resonant readouts of various devices such as detectors, amplifiers, and qubits. We suggest that the phase noise is due to two-level systems in dielectric materials.

The pathway to friendship: Mexico-US trade relations, 1934-1940
Creators: name: Cortez, Julio Edmundo
Publisher: name: University of British Columbia
Year: 2009

description: The relationship between Mexico and the United States during the twentieth century has evolved from one mostly characterized by Mexican economic dependence on the US to one of interdependence between the two countries. In the 1930s, trade became a concrete expression of this interdependence and the link that eventually brought these two countries to friendly terms. The objective of this paper is to evaluate the impact of international trade on the growing interdependence of Mexico and the US between 1934 and 1940. This thesis is structured in two parts. The first section deals with the factors which shaped American foreign policy towards Mexico; the second discusses the Mexican side of the relationship. The two analyses are pulled together in a brief conclusion. The emphasis of this thesis is on the Mexican side of the relationship, and the discussion of American policy serves primarily to provide a context for the subsequent analysis of the factors shaping Mexico’s treatment of the United States. Much of the primary source material used in this thesis was researched in the Banco de Comercio Exterior and the Secretarla de Relaciones Exteriores in Mexico City. Contemporary economic journals and newspapers were also an important source of information; the secondary literature on Mexican-American relations and on the government of Lázaro Cárdenas was also valuable. The thesis concludes that trade was the key element promoting cooperation and that the relationship between Mexico and the United States in the period 1934-1940 was not determined by nationalism, capitalism, imperialism, or any other ‘ism”. The limits of the relationship between the U.S. and Mexico have not been based on some ardent nationalism, but on the shifting interests of the sectors controlling political power in both countries.

The possible application of this higher order contribution to the neutrino effective potential is considered in the context of the Early Universe hot plasma and of the cosmological Gamma Ray Burst fireball. We found that, depending on the medium parameters and on the neutrino properties (mixing angle and mass square difference) the resonant oscillation of active to active neutrinos is possible.

description: Relativistic outflows represent one of the best-suited tools to probe the physics of AGN. Numerical modelling of internal structure of the relativistic outflows on parsec scales provides important clues about the conditions and dynamics of the material in the immediate vicinity of the central black holes in AGN. We investigate possible causes of the structural patterns and regularities observed in the parsec-scale jet of the well-known quasar 3C 273. We present here the results from a 3D relativistic hydrodynamics numerical simulation based on the parameters given for the jet by Lobanov & Zensus (2001), and one in which the effects of jet precession and the injection of discrete components have been taken into account. We compare the model with the structures observed in 3C 273 using very long baseline interferometry and constrain the basic properties of the flow. We find growing perturbation modes in the simulation with similar wavelengths to those observed, but with a different set of wave speeds and mode identification. If the observed longest helical structure is produced by the precession of the flow, longer precession periods should be expected. Our results show that some of the observed structures could be explained by growing Kelvin-Helmholtz instabilities in a slow moving region of the jet. However, we point towards possible errors in the mode identification that show the need of more complete linear analysis in order to interpret the observations. We conclude that, with the given viewing angle, superluminal components and jet precession cannot explain the observed structures.

description: Context: Faraday rotation measurements of extragalactic radio sources during coronal occultation allow assessment of both the electron density distribution and the three-dimensional magnetic field topology in the outer solar corona. Aims: We simulate the three-dimensional structure of both the coronal magnetic field and the electron density distribution in order to reproduce the excess Faraday rotation measures (RMs) of the occulted radio sources observed during solar activity minimum. In particular, we infer the tilt of the solar magnetic axis with respect to the rotation axis. Methods: We compare the output of the model with Very Large Array (VLA) radio polarimetric measurements of a sample of extragalactic sources observed in May 1997. Information on the magnetic field geometry can be retrieved by fine-tuning the set of model free parameters that best describe the observations. Results: We find that predicted and observed Faraday rotation measures are in excellent agreement, thus supporting the model. Our best-fitting model yields a tilt angle $θ_{RB}=3.3^{\circ}$ of the solar magnetic axis with respect to the solar rotation axis around Carrington Rotation 1923. This result is consistent with analogous but independent estimates computed from the expansion coefficients of the photospheric field observed at the Wilcox Solar Observatory (WSO).

The aim of the present thesis was the development of a method for remote heart rate measurement of the patient by analyzing video from webcam using advanced spectral analysis in real time. The estimation of the cardiac pulse is based on automatic face tracking and monitoring the changes in the brightness of the face that are not visible to the human eye. Two algorithms for spectral analysis have been implemented that analyze the signals recorded by the sensors of the camera. The first algorithm uses the technique of ICA (Independent Component Analysis), which uncovers hidden information in a random set of observations and its use in biomedical signal analysis is rapidly expanding. In the second algorithm, the method EEMD (Ensemble Empirical Mode Decomposition) is applied, that is ideally suited to extract components which constitute characteristics of the underlying biological or physiological process. The algorithms were tested using as input signals artificial videos in which the frames follow the change in the real ECG and the results are presented.

description: Στην εργασία αυτή γίνεται μια προσπάθεια ανασύνθεσης των δεδομένων για τον κοινωνιακό χαρακτήρα του κοινωνικού έργου που προσφέρει η ενορία σήμερα ως «ενδοκοινότητα». Στο Α’ Μέρος της εργασίας αποδίδουμε το ιστορικό-θεολογικό πλαίσιο και τις αρχές που διέπουν το κοινωνικό έργο. Ακολουθούν οι διάφορες θεωρητικές προϋποθέσεις, ενώ παράλληλα εξετάζουμε το εξωτερικό περιβάλλον στο οποίο καλείται να δράσει η ενορία. Στο Β’ Μέρος παρουσιάζεται η ιδιαίτερη προβληματική για τα κοινωνικά προβλήματα. Στη συνέχεια αναλύονται τα όρια και βασικές παράμετροι της ενοριακής κοινωνικής προσφοράς, όπως η πνευματική οικοδομή των πιστών, η κοινωνική διάσταση του Λειτουργικού έργου της Εκκλησίας, οι πολύπλευρες δράσεις και δομές υποστήριξης των αδυνάτων. Επίσης, επεξεργαζόμαστε πορίσματα και θέσεις θύραθεν ερευνητών, αναδεικνύοντας τον ρόλο της ενορίας ως παράγοντα κοινωνικοποίησης και συναδέλφωσης των πιστών, αλλά και με την ενεργοποίηση των συνεργιών για την καταπολέμηση των διακρίσεων, της φτώχειας και του κοινωνικού αποκλεισμού. Τέλος παρουσιάζονται τα αποτελέσματα έρευνας στο πεδίο της ενοριακής κοινότητας.
description: In this thesis there is an effort of reconstructing the data about the societal character of the social welfare that is offered by the parish today as a community. In the 1st Part we attach the historical and theological frame and the main principals that govern social action. Subsequently, we give some of the theoretical presuppositions and we also examine the external environment of the modern urban parish. In the 2nd Part we exhibit the earliest data for social problems. Then we analyze the boundaries and the basic parameters of the parish’s social work, such as the social dimension of the Liturgical practice of the Church, the multi-dimension actions and structures to support poor and social excluded people. From a sociological point of view, emerges the socialization and fellowship between parishioners and others, furthermore proposed the activation of co-functioning institutions in order to deal with discriminations, poverty and social exclusion. Finally, the results of the field study are presented.

description: Forest land application of sewage sludge results in the recycling of nutrients essential for plant growth, and also provides organic matter important for soil structure. However, land disposal of sewage sludge is not an ideal solution. A major environmental concern associated with sewage sludge application to land, is the fate of sludge-derived heavy metals such as copper and zinc. Consequently, the mobility and retention mechanisms of sludge—derived metals in forest soils are enormously important to questions of plant uptake and groundwater contamination. The purpose of this study was to examine the mobility and adsorption of sludge-derived copper and zinc in a forest soil. To determine the mobility of the metals a column study was conducted (Phase I) with one main objective: to determine the effect of time and rate of sludge application on the movment and accumulation of copper and zinc in the underlying forest soil. The results of this study indicated significant differences in metal accumulation between application rates in the upper organic horizon (0—5 cm) of the soil. It also became evident that time had a significant effect in the redistribution of metals. Furthermore, and of considerable environmental significance, was the fact that more than 75 % of both copper and zinc remained in the sludge after 4 months. The main objective of Phase II of the research, the Adsorption Study, was to determine the adsorption behaviour of copper and zinc by FH and Bf horizons, and by woody material. The adsorption data was successfully fitted to the Langmuir isotherm. This model provided parameters which reflected both the adsorption capacity and bonding energy of the metal. Results showed that the FH material had a greater bonding energy constant and a higher adsorption capacity for both the metals, than did either of the other two materials. This is significant because the majority of the sludge, when applied to a forest soil, is primarily in contact with the FH horizon. As expected, copper had both a greater bonding energy constant and adsorption maximum than zinc for all three materials. The mobility of sludge-derived copper and zinc in a forest soil is highly dependent upon the adsorption characteristics of the metal with the adsorbate material. Therefore based on the results of this research, it is possible to conclude that in a forest soil with a considerable FH horizon, copper, and to a lesser extent zinc, will be readily adsorbed and retained by this highly organic material.

description: We explore the band dependence of the inferred X-ray temperature of the intracluster medium (ICM) for 192 well-observed galaxy clusters selected from the Chandra Data Archive. If the hot ICM is nearly isothermal in the projected region of interest, the X-ray temperature inferred from a broad-band (0.7-7.0 keV) spectrum should be identical to the X-ray temperature inferred from a hard-band (2.0-7.0 keV) spectrum. However, if unresolved cool lumps of gas are contributing soft X-ray emission, the temperature of a best-fit single-component thermal model will be cooler for the broad-band spectrum than for the hard-band spectrum. Using this difference as a diagnostic, the ratio of best-fitting hard-band and broad-band temperatures may indicate the presence of cooler gas even when the X-ray spectrum itself may not have sufficient signal-to-noise to resolve multiple temperature components. To test this possible diagnostic, we extract X-ray spectra from core-excised annular regions for each cluster in our archival sample. We compare the X-ray temperatures inferred from single-temperature fits when the energy range of the fit is 0.7-7.0 keV (broad) and when the energy range is 2.0/(1+z)-7.0 keV (hard). We find that the hard-band temperature is significantly higher, on average, than the broad-band temperature. Upon further exploration, we find this temperature ratio is enhanced preferentially for clusters which are known merging systems. In addition, cool-core clusters tend to have best-fit hard-band temperatures that are in closer agreement with their best-fit broad-band temperatures. We show, using simulated spectra, that this diagnostic is sensitive to secondary cool components (TX = 0.5-3.0 keV) with emission measures >10-30% of the primary hot component.

description: Στην παρούσα εργασία γίνεται μία προσπάθεια προσδιορισμού όλων των παραμέτρων που επηρεάζουν τη λειτουργία και την αποδοτικότητα ενός σταθμού μετεπιβίβασης, με έμφαση στους σταθμούς που εφαρμόζουν το σύστημα “Park and Ride”. Στη συνέχεια η ανάλυση παραμέτρων αυτών οδηγεί στη διαμόρφωση ενός πλαισίου που περιλαμβάνει τις κατευθυντήριες γραμμές που πρέπει να ακολουθηθούν κατά το σχεδιασμό ενός τέτοιου σταθμού καθώς επίσης και το σύνολο των ερευνών και μελετών που απαιτούνται. Ακολουθεί η διερεύνηση της δυνατότητας δημιουργίας δύο σταθμών “Park and Ride” στη Δυτική Θεσσαλονίκη, ο ένας για την περίπτωση κατά την οποία ο σταθμός θα εξυπηρετεί μελλοντικά μετεπιβιβάσεις με το Τραμ και ο άλλος με το Μετρό. Για κάθε σταθμό παρουσιάζονται δύο σενάρια, ένα για τη σημερινή κατάσταση όπου η μετεπιβίβαση θα γίνεται στις υπάρχουσες λεωφορειακές γραμμές και ένα για τη μελλοντική κατάσταση όπου η μετεπιβίβαση θα γίνεται στο Τραμ/Μετρό αντίστοιχα.
description: The present work is an effort of determination of all parameters that influence the operation and the efficiency of a public transport Terminal, with emphasis on the Terminals that apply the “Park and Ride” system. Afterwards the analysis of these parameters leads to the configuration of a frame that includes the guidelines that should be followed in the designing of such station as well as the total of all researches and studies that are required. Moreover, an attempt is being held in order to investigate the possibility of the construction of two Terminals with supporting “Park and Ride” facilities in the area of Western Thessaloniki, the one for the case in which the station will provide transit services, in the future, with the Tram and the other with the Underground. For each station there are presented two cases, one for the current situation where the Terminal will operate for the existing bus lines and one for the future situation where the Tram or the Underground respectively, will be included in the operations of the Terminal.
Towards Pure Spinor Type Covariant Description of Supermembrane -- An Approach from the Double Spinor Formalism --

description: In a previous work, we have constructed a reparametrization invariant worldsheet action from which one can derive the super-Poincare covariant pure spinor formalism for the superstring at the fully quantum level. The main idea was the doubling of the spinor degrees of freedom in the Green-Schwarz formulation together with the introduction of a new compensating local fermionic symmetry. In this paper, we extend this "double spinor" formalism to the case of the supermembrane in 11 dimensions at the classical level. The basic scheme works in parallel with the string case and we are able to construct the closed algebra of first class constraints which governs the entire dynamics of the system. A notable difference from the string case is that this algebra is first order reducible and the associated BRST operator must be constructed accordingly. The remaining problems which need to be solved for the quantization will also be discussed.

description: Conflicts, inherent in human interactions, present dynamic challenges that demand effective management to prevent escalation into violence. This study delves into the nuanced nature of conflicts, exploring their potential for both constructive and destructive outcomes. The intricate interplay between parties involved in disputes necessitates a thorough understanding of conflict management strategies to foster positive resolutions. The research is grounded in the recognition that not all conflicts inevitably lead to violence; instead, they can serve as catalysts for constructive change. By examining the factors contributing to conflict escalation, this study aims to unravel the tipping points where conflicts transform from potentially constructive dialogues into situations prone to violence. Insights into these critical junctures will inform the development of targeted conflict management interventions. The introductory section lays the groundwork for this exploration, emphasizing the significance of distinguishing between conflicts with constructive potential and those on a path towards violence. Drawing attention to the consequences of poorly managed conflicts, the study underscores the urgency of adopting proactive conflict resolution strategies to mitigate the risk of violence. This research centers on conflicts within [specific context or domain] and their implications for the broader societal fabric. By investigating real-world instances of conflicts within this context, the study seeks to contribute valuable insights applicable to diverse settings. Through comprehensive data analysis and theoretical frameworks, the research aims to provide a nuanced understanding of conflict dynamics, offering a foundation for the development of effective conflict management practices.

description: Η ένταξη των δικτύων GPS στο εθνικό σύστημα αναφοράς γίνεται συνήθως στο τελικό στάδιο των υπολογισμών με ένα μετασχηματισμό ομοιότητας στο προβολικό επίπεδο, που προκύπτει από τη βέλτιστη προσαρμογή των νέων συντεταγμένων των κοινών κορυφών Ελληνικού Γεωδαιτικού Δικτύου – νέου δικτύου GPS, πάνω στις γνωστές τιμές. Η διαδικασία αυτή οδηγεί σε εξάρτηση ή απλή σύνδεση του νέου δικτύου με το εθνικό σύστημα και όχι στην ένταξη με την έννοια που δίναμε στον όρο στα κλασικά δισδιάστατα δίκτυα με παρατηρήσεις γωνιών ή πλευρών και γωνιών, μια και οδηγεί σε νέες συντεταγμένες και για αυτά τα κοινά σημεία μεταξύ του δικτύου πύκνωσης και του εθνικού δικτύου. Η συνόρθωση με το μοντέλο του μετασχηματισμού ομοιότητας που περιγράφεται στην εργασία αυτή αντιστοιχεί στη λύση με πλεονάζουσες δεσμεύσεις των κλασικών δικτύων, όπου οι συντεταγμένες των κοινών κορυφών διατηρούνται σταθερές. Βέβαια, στη λύση αυτή υπάρχει ο κίνδυνος παραμόρφωσης του δικτύου εξαιτίας της πιθανής κακής ποιότητας κάποιας ή κάποιων από τις γνωστές συντεταγμένες, πρόβλημα όμως που αναλύθηκε και αντιμετωπίσθηκε σε πολλές εργασίες της δεκαετίας του 80.
description: The densification of GPS networks in the national reference system is usually performed at the final stage of computations using a similarity transformation on the projective plain, resulting from the best fit of the new coordinates of common stations of Greek Geodetic Network- new GPS network, to the known values. This procedure leads to dependency or simple connection of the new network with the national system and not to integration with the term we gave to classical two dimensional networks with angle or distance and angle observations, since it leads to new coordinates for the common stations between the densification network and national network. The adjustment with the similarity transformation described in this thesis, corresponds to the non-minimal constraints solution of the classical networks, where the common station coordinates remain stable. Of course, with this solution, the risk of network distortion appears due to possible poor quality of some of the known coordinates, a problem that was analyzed and treated in many works in the 80s.
