Multi-resonant metamaterials based on UT-shaped nano-aperture antennas
Hatice Altug, Arif Engin Cetin, Serap Aksu
We demonstrate a compact multi-resonant metamaterial structure based on integrated U- and T-shaped nano-aperture antennas. We investigate the physical origin of the multi-resonant behavior and determine the parameter dependence of the nano-aperture antenna ...
2011Compensator design for improved counterbalancing in high speed atomic force microscopy
High speed atomic force microscopy can provide the possibility of many new scientific observations and applications ranging from nano-manufacturing to the study of biological processes. However, the limited imaging speed has been an imperative drawback of ...
American Institute of Physics2011Real-time registration of airborne laser data with sub-decimeter accuracy
Jan Skaloud, Phillip Tomé, Yannick Stebler
This paper presents a methodology for the precise registering of airborne laser data directly in flight with an accuracy that is sufficient for the majority of derived products, such as digital terrain models. We first present the strategy that integrates ...
2010In-flight quality assessment and data processing for airborne laser scanning
One of the main problems of today's Airborne Laser Scanning (ALS) systems is the lack of reliable data QA/QC (Quality Assurance/ Quality Control) within or shortly after the airborne survey campaign. This thesis presents the development of methods to perfo ...
EPFL2010Evaluation of the frequency stability of a VCSEL locked to a micro-fabricated Rubidium vapour cell
We present our evaluation of a compact laser system made of a 795 nm VCSEL locked to the Rubidium absorption line of a micro-fabricated absorption cell. The spectrum of the VCSEL was characterised, including its RIN, FM noise andline-width. We optimised th ...
2010In-flight Accuracy Estimation for Airborne Lidar Data
One of the main problems of today’s Airborne Laser Scanning (ALS) systems is the lack of reliable data quality assessment within or shortly after the airborne survey campaign. This paper presents the development and implementation of a tool that allows com ...
Inst Navigation, 815 15Th Th St Nw, Ste 832, Washington, Dc 20005 Usa2009Vision-based control of near-obstacle flight
Lightweight micro unmanned aerial vehicles (micro-UAVs) capable of autonomous flight in natural and urban environments have a large potential for civil and commercial applications, including environmental monitoring, forest fire monitoring, homeland securi ...
EPFL2009A noninvasive brain-actuated wheelchair based on a P300 neurophysiological protocol and automated navigation
This paper describes a new noninvasive brain-actuated wheelchair that relies on a P300 neurophysiological protocol and automated navigation. When in operation, the user faces a screen displaying a real-time virtual reconstruction of the scenario and concen ...
Institute of Electrical and Electronics Engineers2009Synchronous EEG Brain-Actuated Wheelchair with Automated Navigation
This paper describes a new non-invasive brain-actuated wheelchair that relies on a P300 neurophysiological protocol and automated navigation. In operation, the subject faces a screen with a real-time virtual reconstruction of the scenario, and concentrates ...
2009Characterization of pressure wave propagation in biological tissues
Kossi Agbeviade, Jacques Giovanola, Alain Curnier, Mathieu Benoit, Marcel Donnet
A measurement technique using flexible PVDF gages for characterizing the propagation of pressure waves in biological tissues is developed. We demonstrated that experimental measurements, coupled with numerical simulations, represent a promising method to o ...
