This paper aims to assess the direct economic impact on maritime sector from its inclusion in European Union-Emission Trading System (EU-ETS). The Monitoring, Reporting and Verification (MRV) data are analysed for estimation of carbon dioxide (CO2) emissions within Economic Area (EEA). assessment model used is scenario-based, includes different price incentives, geographical coverage emission a...

We have investigated the spectral characteristics of a sample of bright γ-ray bursts detected with the γ-ray burst sensors aboard the satellite Ginga. This instrument employed a proportional and scintillation counter to provide sensitivity to photons in the 2 400 keV region and as such provided a unique opportunity to characterize the largely unexplored X-ray properties of γ-ray bursts. The pho...

Ambient noise measured in the deep ocean is studied in the context of a search for high frequency transient signals. The spectral shape of the noise is found to be very stable for an extensive data set collected over several months from 49 hydrophones mounted near the bottom of the ocean at ∼1600 m depth. The slopes of the ambient noise spectra above 15 kHz are found to roll-off faster than the...

In this paper we investigate the performance of different classification paradigms, testing each with a range of acoustic features, to find a system that is well suited to speaker likeability classification. We introduce a Sparse Representation Classifier for paralinguistic classification and explore the role of training data selection for a GMM classifier. Results demonstrate that (1) Single d...

We present a technique for average power reduction in intensity-modulated optical systems using multiple BPSK or QPSK subcarriers with bandlimited pulses, which are, necessarily, not time-limited. In order to insure the non-negativity of the transmitted intensity signal, we use a time-varying bias signal, which is a baseband pulse-amplitude modulation signal also using these pulses. We focus on...

The problem of inter-carrier interference (ICI) in orthogonal frequency-division multiplexing (OFDM) systems has a dramatic impact on their overall performance and robustness. For this reason, various techniques have been proposed in order to eliminate this undesired phenomenon with the most common being the use of transmitter pulse-shaping. Capitalizing on some previous investigations, we here...

High-quality optical sinc-shaped Nyquist pulses with a virtual zero roll-off factor are obtained from the generation of a phase-locked, rectangular-spectrum frequency comb. Tunability over more than 4 frequency decades is demonstrated with <1% power distortion. OCIS codes: (060.4510) Optical communications; (060.4080) Modulation; (320.5540) Pulse shaping.

Several challenges of port/terminal and/or ferry company managers pertain to decisions for the justification of investments and concurrent operational tasks of roll-on/roll-off passenger (RoPax) and roll-on/roll-off (RoRo) systems. This paper explores the possible uses of Modeling and Simulation (M&S) techniques as a decision-support aid for a RoPax/RoRo system managers. A number of use cases a...

Orienting otolith-ocular reflexes were assessed in rabbits using static tilt, off-vertical axis rotation (OVAR) and sinusoidal oscillation about earth-horizontal axes. In all paradigms, head pitch produced ocular counter-pitch and vergence, and head roll produced ocular counter-roll and conjugate yaw version. Thus, vergence and version are essential components of orienting reflexes along the na...

Roll clouds and associated roll convection, are fairly common features of the atmospheric boundary layer. While these organized cumuliform clouds are found over many regions of the planet, they are quite ubiquitous near the edge of the polar ice sheets. In particular, during periods of off-ice flow, when cold polar air flows from the ice pack over the relatively warm ocean water, strong boundar...
