Design Methodology for Controlled-Q Resonators in OTA-based Filters

Pierre-André Farine, Cyril Botteron, Gabriele Tasselli, Saeed Ghamari

This paper presents a design methodology for high quality factor resonators based on operational transconductance amplifier (OTA) employed in active filters. The quality factor of a resonator, as its main specification, is translated to the requirements of ...

Hierarchical Routing Over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

The topology of a mobile wireless network changes over time. Maintaining routes between all nodes requires the continuous transmission of control information, which consumes precious power and bandwidth resources. Many routing protocols have been developed ...

Heracles: Improving Resource Efficiency at Scale

Christos Kozyrakis

User-facing, latency-sensitive services, such as web-search, underutilize their computing resources during daily periods of low traffic. Reusing those resources for other tasks is rarely done in production services since the contention for shared resources ...

Optimal Layered Representation for Adaptive Interactive Multiview Video Streaming

Pascal Frossard, Thomas Maugey, Nikolaos Thomos, Laura Toni, Ana Karina De Abreu Goes

We consider an interactive multiview video streaming (IMVS) system where clients select their preferred viewpoint in a given navigation window. To provide high quality IMVS, many high quality views should be transmitted to the clients. However, this is not ...

Objective Speech Intelligibility Assessment through Comparison of Phoneme Class Conditional Probability Sequences

Hervé Bourlard, Raphaël Marc Ullmann

Assessment of speech intelligibility is important for the development of speech systems, such as telephony systems and text-to-speech (TTS) systems. Existing approaches to the automatic assessment of intelligibility in telephony typically compare a referen ...

Profit Optimization for Wireless Video Broadcasting Systems Based on Polymatroidal Analysis

Pascal Frossard, Yiqiang Chen

This study addresses the problem of profit maximization between wireless service providers (WSPs) and content providers (CPs) in wireless broadcasting systems, while simultaneously providing high quality of experience for end-users (EUs). We first study th ...

A two-stage stochastic programming approach to employee scheduling in retail outlets with uncertain demand

Colin Neil Jones

This paper describes an employee scheduling system for retail outlets; it is a constraint-based system that exploits forecasts and stochastic techniques to generate schedules meeting the demand for sales personnel. Uncertain scenarios due to fluctuating de ...

EEG correlates during video quality perception

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek, Jong Seok Lee, Eleni Kroupi

Understanding Quality of Experience (QoE) in various multimedia contents is still challenging. In this paper, we investigate the way QoE affects brain oscillations captured by electroencephalography (EEG). In particular, sixteen subjects watched 2D and 3D ...

Unconventional photon blockade in doubly resonant microcavities with second-order nonlinearity

Vincenzo Savona

It is shown that noncentrosymmetric materials with bulk second-order nonlinear susceptibility can be used to generate strongly antibunched radiation at an arbitrary wavelength, solely determined by the resonant behavior of suitably engineered coupled micro ...
