The nearest point problem (NPP), i.e., finding the closest points between two disjoint convex hulls, has two classical solutions, the Gilbert–Schlesinger–Kozinec (GSK) and Mitchell–Dem’yanov–Malozemov (MDM) algorithms. When the convex hulls do intersect, NPP has to be stated in terms of reduced convex hulls (RCHs), made up of convex pattern combinations whose coefficients are bound by a mo1 val...

Mode-division multiplexing (MDM) using few-mode fibre (FMF) has received increasing attention to address the exponential growth of data traffic in long-haul optical communication systems. Also, combining MDM with wavelength-division (WDM) is a promising approach for dramatically growing transmission capacity such However, major barrier this regard FMF nonlinear effects, which can significantly ...

We experimentally manipulated nutrient input to a rocky intertidal community, using nutrient-diffusing flowerpots, to determine (i) whether nutrients limited intertidal productivity, (ii) how a large-scale oceanographic disturbance (an El Niño event) affected patterns of nutrient limitation, (iii) the relative impacts of molluscan grazers and nutrient limitation, and (iv) if responses to experi...

Mode division multiplexing (MDM) is an emerging information transmission technique in which multiple data signals can be transmitted simultaneously on different modes of a single wavelength laser beam over free-space channel. MDM potential for the realization high-speed spectral efficient communication links future generations wireless networks. We present novel MDM-based optics (FSO) system. T...

We present a method to extract speaker turn segmentation from multiple distant microphones (MDM) using only delay values found via a crosscorrelation between the available channels. The method is robust against the number of speakers (which is unknown to the system), the number of channels, and the acoustics of the room. The delays between channels are processed and clustered to obtain a segmen...

Data exchange is an important function for flexible optical network, and it has been extensively investigated for the time and wavelength domains. The mode division multiplexing (MDM) has been proposed to further increase the transmission capacity by carrying information on different modes with only single wavelength carrier. We propose and experimentally demonstrate a novel on-chip data exchan...

Modeling is one of the most important factors in the process of computer systems development. It is the process of representing real-world concepts in the computer domains as a blueprint for the purpose of software development. Recent trends in software and system development have also revealed the value of developing systems at higher levels of abstraction. Abstract models streamline and speed...

The use of intervention for time series modelling is a well established technique for on-line forecasting and decision-making in the context of Bayesian dynamic linear models. Intervention has also been recently used in (non-dynamic) Bayesian networks to investigate causal relationships between variables, and in dynamic Bayesian networks to investigate lagged causal relationships between time s...

We investigate the muon anomalous magnetic dipole moment (MDM), the muon electric dipole moment (EDM) and the lepton-flavour-violating decays of the τ−lepton, τ → μγ and τ → 3μ, in the CP-violating Minimal Supersymmetric Standard Model (MSSM) with nonuniversal softsupersymmetry breaking. We evaluate numerically the muon EDM and the branching ratios B(τ → μγ) and B(τ → 3μ), after taking into acc...

ABSTRACT An apertureless near-field scanning optical microscope (a-NSOM) setup is described. Special consideration is given to important system components. Surface plasmons are defined, as is their relationship to aNSOM and their interaction with the scanning probe tip. We used this set-up to measure a metal-dielectric-metal (MDM) antenna integrated with a quantum cascade laser (QCL). The forme...
