Synthetic ground truth data generation for automatic trajectory-based ADL detection
(2014)
In-house automatic activity detection is highly important toward the automatic evaluation of the resident's cognitive state. However, current activity detection systems suffer from the demand for on-site acquisition of ...
Acoustic sustainable environment through freeway traffic management actions
(2014)
Attica Tollway ("Attiki Odos") is a 70-km long tolled motorway in Athens, Greece, in close collaboration with the University of Thessaly -Faculty of Civil Engineering (Laboratory of Transportation Environmental Acoustics ...
Influence of a bent or battered joint or welding on the dynamic loads due to the non-suspended masses of railway vehicles
(2014)
Train circulation is a random dynamic phenomenon and, according to the different frequencies of the loads it imposes, there exists the corresponding response of track superstructure. Random dynamic phenomena are generally ...
Actions on a railway track, due to an isolated defect
(2014)
The rail running table imposes to the vehicle a forced vibration. It is not smooth but instead it comprises a lot of faults that give to the rail running table a random surface. Furthermore under the primary suspension ...
Robust far-field spoken command recognition for home automation combining adaptation and multichannel processing
(2014)
The paper presents our approach to speech-controlled home automation. We are focusing on the detection and recognition of spoken commands preceded by a key-phrase as recorded in a voice-enabled apartment by a set of multiple ...
A demonstration of multirate multicast over an 802.11 mesh network
(2014)
This demo presents a novel multirate multicast scheme for video delivery to wireless users. We demonstrate an adaptive scheme that combines differential backlog scheduling and intelligent packet dropping, both based on ...
Layered evaluation in recommender systems: A retrospective assessment
(2014)
Evaluation of recommender systems has only lately started to become more systematic, since the emphasis has long been on the experimental evaluation of algorithmic performance. Recent studies have proposed adopting a layered ...
Layered evaluation for data discovery and recommendation systems: An initial set of principles
(2014)
This paper examines how a layered evaluation framework proposed for adaptive systems (AS) can be applied in the case of recommender systems (RecSys). Our analysis indicates that implementing a layered-based evaluation has ...
Demo: Enabling AGILE spectrum adaptation in commercial 802.11 WLAN deployments
(2014)
In this work, we present the AGILE Spectrum Adaptation system that is able to dynamically tune the channel central frequency and bandwidth of wireless links in an adaptive to the interference and trafic conditions way. The ...
Optimizing video quality in dense small-cell wireless networks with packet overhearing
(2014)
The heterogeneous wireless network (HetNet) paradigm is based on the deployment of low power small cell base stations (SCBS) close to the user in parallel with a macrocell BS (MBS) that provides umbrella coverage. However, ...
