The seminars will kick-off with a free seminar, that will take place over the weekend of 20 & 21 September 2014 at the Main Auditorium of N.C.S.R. "Demokritos".

WiCom at the NCSR Demokritos Summer School 2014

Dr. K. Peppas, member of WiCom laboratory, gave a lecture entitled: "Modern wireless communication networks", at the Summer School organized by NCSR Demokritos, between 7 and 18 July 2014.

Τρισδιάστατα Εικονικά Εργαστήρια

Ευρύτερος στόχος της ερευνητικής δράσης OnLabs είναι η ανάπτυξη τεχνολογίας για την ανακάλυψη, δοκιμή και αξιολόγηση τεχνικών εκπαίδευσης σε σχέση με διάφορα καθήκοντα και λειτουργίες που λαμβάνουν χώρα εντός ενός ρεαλιστικού περιβάλλοντος. Ως ρεαλιστικό θεωρείται ένα περιβάλλον όπου οι χρήστες αλληλεπιδρούν με διάφορα αντικείμενα που είναι μέσα στο περιβάλλον και με την αλληλεπίδραση αποκτούν μαθησιακή εμπειρία ή δεξιότητες χειρισμού των αντικειμένων ή δεξιότητες εκτέλεσης σύνθετων δραστηριοτήτων/διαδικασιών.

Detecting all repeated patterns in sequences using suffix arrays

Pattern detection is a topic of great interest for many sciences. Suffix trees and suffix arrays are the most commonly used data structures for this purpose. For such purposes we have created the novel algorithm ARPaD, which uses the suffix array under a new perspective. With the use of the recursive algorithm ARPaD over the actual suffix array we can perform a fast analysis of any kind of sequences and detect all repeated patterns in linear time complexity.

Modelling of body-centric communications channel: Investigation of the influence of wearable antennas and user mobility

In recent years the amount of wearable devices on human body has been dramatically increased with various functionalities being served in many areas. The trend of incorporating more and more wearable devices in our everyday life has come to fulfil the need for closer and accurate monitoring and preventing in healthcare, but also for entertainment, fitness and convenience purposes.

Optimal Power Allocation in Block Fading Gaussian Channels with Secrecy Constraints

Physical layer security (PLS) investigates the potential of exploiting impairments of real communication channels, such as fading and noise, in order to achieve confidentiality in information exchange. PLS was pioneered by Wyner, who introduced the wiretap channel and established the possibility of creating perfectly secure communication links without relying on private (secret) keys. Recently, considerable efforts have been channelled to generalizing this result to the wireless fading channel and to multi-user scenarios.

The Telecoms Lab-Net Media Lab organized a free online webinar entitled "Introduction to Vocational Guidance with the use of ICTs" with the participation of more than 350 people.

The pyramid quantized Weisfeiler-Lehman graph representation

Graphs are a technique to represent data with inherited structure. Despite the signi cant progress in graph kernels, existing graph kernels focus on either unlabeled or discretely labeled graphs, while efficient and expressive representation and comparison of graphs with continuous high-dimensional vector labels, remains an open research problem. We introduce a novel method, the pyramid quantized Weisfeiler-Lehman graph representation to tackle the graph comparison problem for continuous vector labeled graphs.

Multimedia Concept Detection in Large-scale Settings with Laplacian Eigenmaps

The presentation describes a semi-supervised framework based on a fast and efficient feature representation with a highly scalable learning approach, achieving high accuracy and substantial gains in computational cost. The framework makes possible to implement a semi-supervised approach in large-scale settings.
