A novel framework for retrieval and interactive visualization of multimodal data
No full textWith the abundance of multimedia in web databases and the increasing user need for content of many modalities, such as images, sounds, etc., new methods for retrieval and visualization of multimodal media are required. In this paper, novel techniques for retrieval and visualization of multimodal data, i.e. documents consisting of many modalities, are proposed. A novel cross-modal retrieval framework is presented, in which the results of several unimodal retrieval systems are fused into a single multimodal list by the introduction of a cross-modal distance. For the presentation of the retrieved results, a multimodal visualization framework is also proposed, which extends existing unimodal similarity-based visualization methods for multimodal data. The similarity measure between two multimodal objects is defined as the weighted sum of unimodal similarities, with the weights determined via an interactive user feedback scheme. Experimental results show that the cross-modal framework outperforms unimodal and other multimodal approaches while the visualization framework enhances existing visualization methods by efficiently exploiting multimodality and user feedback

Branding for startup companies in Sweden : A study on startups brand building
No full textAim: The aim of this study is to explore the factors that influence the brand building in startup companies. Method: This study implements a qualitative approach and consists of twelve startup companies located in Sweden. Results and Conclusion: The findings suggest that the design of a brand (name and visual aspects), the use of social media, event participation and establishing partnerships is important parts of brand building. In addition, startups frequently make use of employees’ and entrepreneurs’ individual personality for branding purposes. Not only do all participants view branding as an important part of their business but a few respondents even feel it is crucial for the survival of their business. Suggestions for further research: The participants of this study reside in separate industries. This, combined with the sample size is not evidence enough to draw conclusion upon similarities and differences between startups branding practices in terms of industry. Thus, this could be interesting undertaking in the future due to the limited research on this topic. Contribution of the study: This study adds to the existing body of knowledge by uncovering factors such as brand design and social media, to name a few, that is used by startups to build their brand. As a result of this study insights has been given on the importance of branding and the strategies used to increase the brand equity of startups
Novel 3D processing methods for 3D object search and retrieval
No full textThe number of the available 3D objects has been significantly increased during the
last years, mainly due to the rapid growth of the computer hardware and software. In
the new network era, the need for reliable 3D object retrieval tools is emerging. In this
thesis, three novel methods for 3D object representation capable for 3D object retrieval
have been proposed. In the first approach, the 3D object is represented by an attributed
graph, where the topology of the object is encoded in the topology of the graph and every
graph element (nodes and edges) is attributed with geometric descriptors. The geometric
descriptors are based on the approximation of every part with a super-ellipsoid and the
novel 3D distance field descriptor. The matching is based on attributed graph matching. The
second approach proposes a novel 3D shape representation. The 3D object is considered
as a distributed 3D mass and the descriptor of the 3D object is indirectly computed from
the resulting fields. The field is described using both Newton's and general relativity's
laws. In the Newtonian approach, histograms of the field values in the surrounding area
of the 3D object are computed, while in the relativistic approach the descriptors are
histograms of the time–space curvature in the surrounding area of the 3D object. The
matching method utilizes histogram matching approaches. The third method is based on
the theory of Ellipsoidal Harmonics. Every object can be decomposed in an Ellipsoidal
Harmonic series. Three instances of the Ellipsoidal Harmonic Descriptor are proposed
and finally the Ellipsoidal Harmonics are combined to Spherical harmonics resulting in a
powerful descriptor. Experiments which were performed in various 3D object databases
proved the retrieval efficiency of the proposed approaches.Τα τελευταία χρόνια, η ανάπτυξη των υπολογιστών και η διάδοση του διαδικτύου,
έχουν οδηγήσει στη δημιουργία μεγάλου αριθμού 3Δ αντικειμένων, γεγονός που καθιστά
επιτακτική την ανάγκη δημιουργίας αξιόπιστων εργαλείων αναζήτησης και ανάκτησης 3Δ
αντικειμένων. Στα πλαίσια της παρούσας διατριβής έχουν αναπτυχθεί τρεις καινοτόμες
μεθοδολογίες επεξεργασίας και μαθηματικής αναπαράστασης του γεωμετρικού σχήματος
των 3Δ αντικειμένων ώστε να αξιοποιηθούν σε συστήματα αναζήτησης και ανάκτησης 3Δ
αντικειμένων. Η πρώτη μέθοδος, προτείνει την αναπαράσταση των 3Δ αντικειμένων με
χρήση επαυξημένων γράφων, όπου η τοπολογία του γράφου αναπαριστά την τοπολογία
του 3Δ αντικειμένου, ενώ κάθε στοιχείο του γράφου (κόμβοι και ακμές) επαυξάνεται
με χρήση γεωμετρικών περιγραφέων. Οι γεωμετρικοί περιγραφείς στηρίζονται στην
προσέγγιση με υπερελλειψοειδή και στον υπολογισμό πεδίου αποστάσεων από το
υπερελλειψοειδές. Η σύγκριση των αντικειμένων βασίζεται στη θεωρία εύρεσης
ομοιότητας μεταξύ επαυξημένων γράφων. Η δεύτερη μέθοδος αντιμετωπίζει τη
3Δ γεωμετρία από μια διαφορετική σκοπιά, καθώς θεωρεί το αντικείμενο σαν μια
κατανεμημένη μάζα στο κενό και βασίζει την μαθηματική αναπαράσταση που το
περιγράφει στο βαρυτικό πεδίο που δημιουργείται στον περιβάλλοντα χώρο του. Το
πεδίο περιγράφεται με χρήση ιστογραμμάτων που προέρχονται από την εφαρμογή
του νόμου της παγκόσμιας έλξης (και γενικεύσεις αυτού), καθώς και απλοποιημένες
μορφές της γενικής θεωρίας της σχετικότητας. Η σύγκριση των περιγραφέων αξιοποιεί
μετρικές ομοιότητας μεταξύ ιστογραμμάτων. Η τρίτη μέθοδος, εισάγει τη χρήση των
ελλειψοειδών αρμονικών στην αναπαράσταση των 3Δ αντικειμένων. Κάθε αντικείμενο,
ανεξάρτητα από τη μορφή αναπαράστασής του, μπορεί να αναπτυχθεί σε ένα σύνολο
συναρτήσεων βάσης, που αποτελούν οι ελλειψοειδείς αρμονικές. Προτείνονται τρεις
παραλλαγές των ελλειψοειδών αρμονικών, καθώς και ο συνδυασμός των ελλειψοειδών
αρμονικών με τις καθιερωμένες σφαιρικές αρμονικές. Τα πειραματικά αποτελέσματα
όλων των μεθόδων σε ένα σύνολο διαφορετικών βάσεων 3Δ αντικειμένων αναδεικνύουν την αποτελεσματικότητα τους
Improving Brand Equity with Environmental Sustainability work : A qualitative study in Sweden
No full textSustainability is increasing in importance nowadays and Sweden is one of the most sustainability- focused countries in the world. Environmental sustainability is considered to be a key factor for business growth and companies incorporate this aspect in their brand marketing strategies. The purpose of this study is to get a broader understanding of the field of environmental sustainability work in connection to brand equity in Sweden. The main contribution of this study derives from studying how companies work with environmental sustainability to improve brand equity from a company’s perspective in Sweden. A qualitative approach was chosen, which included semi- structured interviews with seven companies that operate in Sweden. This paper develops an analytical model in order to analyse the findings from the interviews. The findings suggest that companies can work with environmental sustainability to improve their brand equity in Sweden by using strategies and practices that fit the company. It is important to consider the local context of Sweden, the market demands and requirements of its stakeholders and adopt a holistic approach in order to improve brand equity. Companies can choose to incorporate environmental sustainability work as an add-on to their brand or base the core of the brand around their work

The certified thesis is available in the Institute Archives and Special Collections.This thesis investigates peak-to-average ratio (PAR) reduction techniques for multicarrier modulation systems, such as discrete multitone (DMT) modems and orthogonal frequency-division multiplexed (OFDM) terrestrial broadcast transmitters. Through simulation and test implementation on a state-of-the-art programmable ADSL development platform, this thesis pursues a suitable solution for minimizing PAR given the resources of a programmable platform. This solution is integrated as a prototype implementation into a fully-functional ADSL modem and optimized for maximum PAR reduction performance within modem complexity constraints.by Athanasios Dimitri Dousis.M.Eng
Homophobic Statements, a Bishop, and the Limits of Freedom of Expression. An In-Depth Commentary on ECtHR 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20
No full textDichiarazioni omofobe, un vescovo e i limiti della libertà di espressione. Un commento approfondito su CEDU 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20.
ABSTRACT: The decision of the ECtHR of 31.08.2023, Amvrosios-Athanasios Lenis v. Greece (no. 47833/20), is a further step toward an increasingly dense jurisprudence on “hate speech” and the limits of freedom of expression. The public proclamation of religious doctrines that are in conflict with the values of the contracting States enshrined in the ECHR is protected to a certain extent by the fundamental right of freedom of religion and belief. However, the qualification of a statement as religious does not justify “hate speech.” The AUTHOR shows the tension between freedom of religion, freedom of expression, and protection against discrimination, and analyzes the decision against the backdrop of Article 17 of the ECHR (prohibition of abuse of rights).

La tomba III di Haghios Athanasios e il valore semantico dell'incarnato
No full textThe tomb III at Haghios Athanasios stands out among the Macedonian tombs for the exceptional painted decoration of the temple-like façade. Excavated in the '90s by M. Tsimbidou-Avloniti it has been published by the scholar in full detail and the iconographic program of the monument has been the object of many publications. This article re-examines the different ways of reproducing the skin color (το ανδρείκελον) in the figures of the miniature frieze and in the megalographic figures beside the door. The realistic rendering of the megalographic figures of armed men in Macedonian attire, showing their sorrow for the lost of an etairos, is contrasting with the pale color of the participants to the symposion in the frieze above the door, a scene whose illusionistic overtone has been yet perceived by the critics. This symposion is articulated in three scenes and it can be interpeted as a necrodeipnon, but in the same time as a celebration of the Macedonian banquet style, centered on the royal court. The author suggests that the first figure on the right of the frieze, related to the group of armed men looking towards the banqueters feasting in the center of the frieze, can be read as the dead himself, for the particular rendering of his ανδρείκελον, showing the typical ochròtes or necròdes face color, according to the contemporary medical lexicon. The pathetic stance assumed by the same figure, the sole in the group which is not bearing arms, seems to confirm his role in the context of the scene
