Conducting a virtual ensemble with a kinect device
(KTH Royal Institute of Technology Sound and Music Computing Group, 2013)This paper presents a gesture-based interaction technique for the implementation of an orchestra conductor and a virtual ensemble, using a 3D camera-based sensor to capture user’s gestures. In particular, a human-computer ... -
Virtual Conductor for String Quartet Practice
(KTH Royal Institute of Technology Sound and Music Computing Group, 2013)This paper presents a system that emulates an ensemble conductor for string quartets. This application has been developed as a support tool for individual and group practice, so that users of any age range can use it to ... -
A general approach for robust integrated polarization rotators
(International Society for Optics and Photonics, 2013)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Engineering the optical properties of silicon using sub-wavelength structures
(IEEE Photonics Society, 2013)In most integrated optics platforms, including silicon-on-insulator, only minor modifications in refractive index are possible. The geometry of the waveguiding structure is thus the only degree of freedom for the design ... -
Varactor-Tuned Dual-Mode Frequency Discriminator for Instantaneous Frequency Measurements
(IEEE European Microwave Week, 2013)In this paper a novel varactor-tuned frequency discriminator that makes use of two tunable dual-mode microstrip resonators is demonstrated which doubles the discriminator tuning bandwidth. To prove its validity a prototype ... -
Re-inventing Multimode Interference Couplers Using Subwavelength Gratings
(European Physical Society, IEEE, The Optical Society, 2013)We use the concept of subwavelength grating (SWG) refractive-index-engineering to propose and experimentally demonstrate a reduced size, slotted 2x2 MMI coupler. We also present an ultra-broadband 2x2 MMI coupler which ... -
Network Anomaly Classification by Support Vector Classifiers Ensemble and Non-linear Projection Techniques
(Springer, 2013-09)Network anomaly detection is currently a challenge due to the number of different attacks and the number of potential attackers. Intrusion detection systems aim to detect misuses or network anomalies in order to block ports ... -
Caracterización y Simulación de un Diodo Schottky de Microondas
(2013-09)Microwave diode models included in commercial simulators use a large set of parameters, so they are often difficult to set up in order to match the actual response of a specific device. In this paper a simple model for a ... -
Discriminador de frecuencia basado en resonadores “dual-mode” sintonizables
(2013-09)In this paper a novel varactor-tuned frequency discriminator that makes use of two tunable dual-mode microstrip resonators is demonstrated. In this circuit, the two tuned modes of the resonators are used independently to ... -
Secure Distributed System inspired by Ant Colonies for Road Traffic Management in Emergency Situations
(2013-09-04)In this work, we present a distributed system designed for road traffic management. The system is inspired by the behavior of the ant colonies. The distributed design responds to the particular limitations of an emergency ... -
Consideraciones sobre el amplificador distribuido como amplificador de potencia
(2013-09-12)In this contribution, a short review of independent research activities on distributed power amplification is presented. An analysis of the intrinsic limitations of distributed power amplifiers serves as a guideline to ... -
Arrays planares basados en el elemento strip-slot complementario
(2013-09-13)Recently, the authors introduced a novel planar radiating element that exploits the characteristics of the slotline microstrip coupling to obtain a microstrip-fed slot with broadband matching. This paper reviews the main ... -
