Improving the speed and accuracy of indoor localization:
No full textAdvances in technology have enabled a large number of computing devices to communicate wirelessly. In addition, radio waves, which are the primary means of transmitting data in wireless communication, can be used to localize devices in the 2D and 3D space. As a result there has been an increasing number of applications that rely on the availability of device location. Many systems have been developed to provide location estimates indoors, where Global Positioning System (GPS) devices do not work. However, localization indoors faces many challenges. First, a localization system should use as little extra hardware as possible, should work on any wireless device with very little or no modification, and localization latency should be small. Also, wireless signals indoors suffer from environmental effects like reflection, diffraction and scattering, making signal characterization with respect to location difficult.
Moreover, many algorithms require detailed profiling of the environment, making the systems hard to deploy.
This thesis addresses some of the aforementioned issues for localization systems that rely on radio properties like Received Signal Strength (RSS).
The advantage of these systems is that they reuse the existing communication infrastructure, rather than necessitating the deployment of specialized hardware. Specifically, we improved the latency of a particular localization method that relies on Bayesian Networks (BNs). This method has the advantage of requiring a small size of training data, can localize many devices simultaneously, and some versions of BNs can localize without requiring the knowledge of the locations where signal strength properties are collected.
We proposed Markov Chain Monte Carlo (MCMC) algorithms and evaluated their performance by introducing a metric which we call relative accuracy.
We reduced latency by identifying MCMC methods that improve the relative accuracy to solutions returned by existing statistical packages in as little time as possible. In addition, we parallelized the MCMC process to improve latency when localizing devices whose number is on the order of hundreds. Finally, since wireless transmission is heavily affected by the physical environment indoors, we investigated the impact of using multiple antennas on the performance of various localization algorithms. We showed that deploying low-cost antennas at fixed locations can improve the accuracy and stability of localization algorithms indoors.Ph.D.Includes bibliographical references (p. 103-106)by Konstantinos Kleisouri
Aghios Konstantinos church in Athens. Conservation planning
No full textThis piece shows the conservation project made for Aghios Konstantinos church, Athens, Greece. Starting from the investigation of the urban development of the city, passing through the study of the architectural grammar of the building and eventually addressing to the material characterisation and pathologies of the church, this work tries to provide a strong analytical support for the conservation intervention. We investigated Athens urban development dividing the timeline in eight phases, from the Ancient Age until now. Aim of this task is to supply a strong understanding of why Aghios Konstantinos church was built in a particular point of the city, and which are its historic and artistic values that need to be preserved and passed on future generations. We narrowed the focus of our investigation lens afterwards. We studied the building concentrating on its architectural grammar. Precisely, the architectural style is both complex and traditional: Kaftantzoglou, the author, tried to merge byzantine elements with classical ones, in a modern eclectic-neo-classical shape. We examined material characterisation and investigation of damage using NORMAL tables, separating different materials and individuating typical pathologies for each of them in the main façade. Atmospheric agents and, mainly, humidity caused most decays. Interventions on the façade were planned strictly respecting minimum interventum, sustainability and reversibility. Finally, a survey of structural damage indoors and outdoors revealed stability problems in the vault, in the arches, and in the pillars below. Although the church was built only in the 19th century, it showed serious structural damages, mainly caused by two strong earthquakes that occurred in 1981 and in 1999. The consolidation project focused on the dome: we planned a Fiber Reinforced Polymer (FRP) hooping around it, calculating the strains on meridians and parallels and, eventually, applying a traction verification
Correlational study of empathy and violence in patients with schizophrenia and antisocial personality disorder
No full textA paucity of cognitive and affective features of empathy can be correlated with violent behavior. We aimed to identify differences in empathy among four groups in a sample of 100 male participants: (1) 27 violent offenders with schizophrenia, (2) 23 nonviolent patients with schizophrenia, (3) 25 patients with antisocial personality disorder, and (4) 25 subjects from the general population, who formed the control group. Schizophrenia symptoms were quantified with the Positive and Negative Syndrome Scale. Empathy was measured with the empathy quotient. Theory of mind was evaluated using (a) the first-order false-belief task, (b) the hinting task, (c) the faux pas recognition test and (d) the “reading the mind in the eyes” test (revised). Differences noted among the groups were age (controls were younger) and educational status (antisocials were less educated). The empathy quotient scoring (p < 0.001) and theory-of-mind tests (p < 0.001) were distinct between the control group and the three other groups of participants, but not among the three patient groups. Patients with antisocial personality disorder, violent psychotic offenders and psychotic nonviolent patients show no remarkable differences in affective or cognitive empathy tests, but they all present deficits in empathy and theory of mind when compared to controls.Η έλλειψη γνωσιακών και συναισθηματικών χαρακτηριστικών της ενσυναίσθησης μπορεί να συσχετιστεί με βίαιη συμπεριφορά. Στόχος μας ήταν να εντοπίσουμε διαφορές στην ενσυναίσθηση μεταξύ τεσσάρων ομάδων σε ένα δείγμα 100 ανδρών συμμετεχόντων εκ των οποίων: (1) 27 βίαιοι παραβάτες με σχιζοφρένεια, (2) 23 μη βίαιοι ασθενείς με σχιζοφρένεια, (3) 25 ασθενείς με αντικοινωνική διαταραχή προσωπικότητας και (4) 25 άτομα από τον γενικό πληθυσμό, που σχημάτισαν την ομάδα ελέγχου. Τα συμπτώματα της σχιζοφρένειας ποσοτικοποιήθηκαν με την κλίμακα θετικού και αρνητικού συνδρόμου(PANSS). Η ενσυναίσθηση μετρήθηκε με το πηλίκο ενσυναίσθησης (EQ). Η θεωρία του νου αξιολογήθηκε χρησιμοποιώντας (α) τη δοκιμασία εσφαλμένης πεποίθησης πρώτης τάξης (β) τη δοκιμασία υπαινιγμού, (γ) τη δοκιμασία αναγνώρισης faux pas και (δ) τη δοκιμασία «διαβάζοντας το μυαλό στα μάτια» (αναθεωρημένη). Οι διαφορές που παρατηρήθηκαν μεταξύ των ομάδων αφορούσαν την ηλικία (οι μάρτυρες ήταν νεότεροι) και την εκπαίδευση (οι αντικοινωνικοί ήταν λιγότερο μορφωμένοι). Η βαθμολογία του πηλίκου ενσυναίσθησης (p < 0,001) και οι δοκιμασίες θεωρίας του νου (p < 0,001) ήταν διακριτές μεταξύ της ομάδας ελέγχου και των τριών άλλων ομάδων συμμετεχόντων, αλλά όχι ανάμεσα στις τρεις ομάδων ασθενών. Οι ασθενείς με αντικοινωνική διαταραχή προσωπικότητας, οι βίαιοι ψυχωτικοί παραβάτες και οι ψυχωτικοί μη βίαιοι ασθενείς δεν παρουσιάζουν αξιοσημείωτες διαφορές στις δοκιμασίες συναισθηματικής ή γνωσιακής ενσυναίσθησης, αλλά όλοι παρουσιάζουν ελλείμματα στην ενσυναίσθηση και τη θεωρία του νου σε σύγκριση με την ομάδα ελέγχου
Segmentectomy versus lobectomy. Which factors are decisive for an optimal oncological outcome?
No full textLow-dose computed tomography is being used for lung cancer screening in high-risk groups. Detecting lung cancer at an early stage improves the chance of optimal treatment and increases overall survival. This article compares segmentectomy vs. lobectomy as surgical options, in the case of stage I non-small cell lung carcinoma, ideally IA. To compare the 2 previously referred strategies, data were collected from articles (40 studies were reviewed), reviews, and systematic analyses in PubMed Central, as well as reviewing recent literature. Segmentectomy could be an equal alternative to lobectomy in early-stage NSCLC (tumour < 2 cm). It could be preferred for patients with a low cardiopulmonary reserve, who struggle to survive a lobectomy. As far as early-stage NSCLC is concerned, anatomic segmentectomy is an acceptable procedure in a selective group of patients. For better tumour and stage classification, a systematic lymph node dissection should be performed
Mobilization follies in international relations: A multimethod exploration of why some decision makers fail to avoid war when public mobilization as a bargaining tool fails
No full textThis paper is intended to serve as a show and tell model for graduate students. Sections in parentheses and italics provide a running commentary by the author on the decisions taken throughout the paper. The goal is to permit students to follow the thinking of the researcher and see how it guided the theoretical, methodological and other decisions on content that finally made it into the paper. The paper in question explores how "public" military mobilization can be an attempt by weak actors to trigger intervention by third parties in a dispute with a stronger actor, in the hopes that the third parties will force the stronger actor to accommodate the weaker actor. This attempt is called "compellence via proxy". In this research I explore why in reaction to failure, some weak actors are able to avoid escalation to war, while others are not. I posit that the flexibility of the decision makers of the weak actors is influenced by their ability to overhaul their winning coalition. A large-n evaluation of 68 cases of "public" mobilization, and an evaluation of six Balkan state mobilizations in the 1878-1909 em, do not support the idea that the size of the winning coalition, a part of the factors determining overhaul, has an association with war onset or its avoidance.Publisher versio

Johanna Mylonaki DEPARTMENT: Institute of Greek and Latin Studies SUPERVISOR: PhDr. Konstantinos Tsivos, Ph.D. ABSTRACT: My dissertation is dealing with the phenomenon of "brain drain" on the example of the Greeks, who moved to the Czech Republic after 1992, after the declaration of independence of the Czech Republic. My thesis will firstly focus on the history of the Greek diaspora in Czechoslovakia and later the Czech Republic. Then, I will describe the course of the Greek financial crisis and especially the "brain drain" phenomenon. The main goal of this thesis is to map the current state of the Greek community in the Czech Republic with an emphasis on new immigrants. In the practical part of the thesis, I will evaluate the results of a structured questionnaire with which I will address Greeks who moved to the Czech Republic during their lifetime.
