Controlled multi-beam supercontinuum generation in fused silica by means of spatial light modulators
(IEEE, 2015-06)
We report on deterministic femtosecond multi-filamentation in fused silica by encoding a diffractive microlens array into a spatial light modulator. The efficiency and focal length of each microlens are electronically ...
Security and Reliability of Room Occupancy Detection Using Probe Requests in Smart Buildings
(IEEE, 2023-04-19)
We present new approaches for determining occupancy in smart building management systems. The solutions can be applied dually, in civil and military areas, not only for economic management but also in crisis situations ...
All-fiber incoherent frequency-to-time mapping method for microwave signal generation with baseband transmission and multicasting support
(Elsevier, 2008)
We present a proof-of-principle experiment for achieving simultaneous distribution of baseband radio-frequency data and up-conversion with broadcasting support over a passive optical network. The technique is based on an ...
Flat-top ultra-wideband photonic filters based on mutual coherence function synthesis
(Elsevier, 2008)
A novel all-incoherent optical circuit that allows for band-pass microwave-photonic filter design is presented and verified through numerical simulation. In contrast to conventional spectrum-sliced optical architectures ...
Managing user-generated information in geospatial cyberinfrastructures
(Elsevier, 2011)
Information systems built using standards-based distributed services have become the default computing paradigm adopted by the geospatial community for building information infrastructures also known as Spatial Data ...
Efficient visualization of 3D models on hardware-limited portable devices
(Springer, 2014)
Managing the geometry of a 3D scene efficiently is a key aspect of an interactive 3D application. This aspect is more important if we target at portable devices, which have limited hardware capabilities. Developing new ...
Visualization of level-of-detail meshes on the GPU
(Springer Verlag, 2011-09-01)
Extensive research has been carried out in multiresolution
models for many decades. The tendency in recent
years has been to harness the potential of GPUs to
perform the level-of-detail extraction on graphics hardware.
The ...
Spatial recurrences for pedestrian classification
(Springer U.S., 2012-09)
In this work, a framework is proposed for pedestrian classification based on spatial recurrences in the form of recurrence plots. This representation is more general and potentially more discriminative than a histogram of ...
Geostatistical methods to identify and map spatial variations of soil salinity
(Elsevier, 2011-01)
The problem of estimating and predicting spatial distribution of a spatial stochastic process, observed at irregular locations in space, is considered in this paper. Environmental variables usually show spatial dependencies ...
The space-bandwidth product in the join ttransform correlator optical encryption setup
(Elsevier, 2011)
In this work we study the joint transform correlator (JTC) optical encryption setup through the Wigner function. We found analytical expressions for the spatial and spatial frequency extent of the encrypted signal. Since ...
