We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service s ...
Scalability is a powerful concept for adaptive video content delivery to many end users having heterogeneous and dynamic characteristics of networks and devices. In order to maximize users' quality of experience by selecting appropriate combinations of mul ...

Research in the field of video quality assessment relies on the availability of subjective scores, collected by means of experiments in which groups of people are asked to rate the quality of video sequences. The availability of subjective scores is fundam ...
This talk starts by defining what is Quality of Experience. It then provides an overview of state of the art in Quality of Experience in multimedia systems. It will finally conclude by presenting challenges and trends that need to be further addressed. ...
Multimedia signals, such as digital images and video sequences, are captured, processed and finally presented to human observers who directly or indirectly judge their quality. During the data acquisition, as well as the many steps of the processing chain, ...
Dual eye tracking offers new possibilities for the analysis and diagnosis of collaborative interaction. Cross-recurrence analyses and visualizations offer insight into how closely two collaborators’ gaze follow each other. We contrast two cases to illustra ...

Approximately 25 percent of the budget for the maintenance and renewal of railway tracks –in Switzerland more than a billion Swiss Francs– is used for the switches (points) and crossings (S&C). While in the mean time the budget expenditure for the maintena ...
Confidential communication aided by a relay without security clearance is studied. General strategies and outer bounds are derived for the problem of secret communication and secret key generation when correlated observations at all terminals are available ...

Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive model to approximate Hilbert envelopes in frequency sub-bands for relatively long temporal segments. Although the basic technique achieves good quality of the reconstructe ...
This paper reports the low power operation of Vibrating Body Field Effect Transistors as active resonators for communication applications. For the first time we report active resonators operating at 2MHz and 20MHz with power consumption less than 100μW and ...
