The MOWE-IT project shall assess factors that prerequisite cross-modal transferability between the air and surface-based European transport systems in order to protect the passengers, shippers, European institutions and citizens against travel delays, cancellations and/or stoppages in freight transfer caused by extreme weather and/or other natural disasters. The on-going WEATHER and EWENT- projects have established how the different extreme weather events harm the safety and security of passengers and drivers, reduce the inter-urban and regional accessibility, disrupt logistics chains, delay cargo delivery, inflate supply costs for operators and consignees, and immobilise public infrastructure. However, there is still a need to find out how the air and surface transport systems may improve operational resilience by substituting each others services when suffering from traffic curtailment, infrastructure shutdowns, and/or capacity shortages caused by emergencies. Therefore, the MOWE-IT project shall assess how the companies in passenger and freight transport comply with the European users rights protection legislation shielding theses parties against travel delays, cancellations and/or disruptions, and in case of gaps in conformity, propose new guidelines for cross-modal alignment of decision-making, capacity planning and reserve-building models at transport service and infrastructure providers in addition to incentive structures and policy instruments for more effective legislation enforcement. Such an assessment will also draw from the possibilities to use weather and other information technologies to aide the transport system and operators. The project will have 9 work packages, which focus on management and dissemination, transport-mode specific issues and cross-modal considerations and finally to short-term and long-term solutions and policy options for reducing the negative impacts of extreme weather and natural disasters.

An algorithm of embedding the digital watermarks into speech signals transmitted through analog channels of VHF radio telephony of the maritime and aeronautical mobile services has been designed. For embedding DWM it was proposed to use the vector quantization of the complex envelope of narrow-band signal. DWM robustness to the intersymbol interference, multiplicative and additive interferences is provided, respectively, by the following means: 1) formation of narrow-band channels, 2) step-size adaptation in the transmitter and receiver, and 3) distribution of DWM energy over L samples. This algorithm makes it possible to implement the automatic identification of radiotelephone transmissions without the replacement of the standard radio communication equipment and variation of the operation procedures of radio telephony. © 2011 Allerton Press, Inc.

Application of orthogonal frequency division multiplexing (OFDM) is suggested for digital watermarking (DWM) in VHF radiotelephony of maritime mobile service. Algorithm of normalized spreading of DWM energy in the method of improved spread spectrum (ISS) considering information on carrier signal and DWM detection method based on hash function are designed. The OFDM-ISS method allows for achieving the DWM rate of 60-268 bit/sec in the conditions of their acoustic stealthiness in the problem of automatic radiotelephone transmissions identification using existing radio communications equipment. © 2012 Allerton Press, Inc.

The stress intensity factors (SIF) for a plane circular crack in a finite cylinder undergoing torsional vibrations are determined. The vibrations are generated by a rigid circular plate attached to one end of the cylinder and subjected to a harmonic moment. The boundary-value problem is reduced to the Fredholm equation of the second kind. This equation is solved numerically, and the solution is used to derive a highly accurate approximate formula to calculate the SIFs. The calculated results are plotted and analyzed © 2012 Springer Science+Business Media, Inc.

The algorithm of high capacity digital watermarks embedding into the speech signals using OFDM-technology has been worked out. For DWM embedding it is suggested to apply vector quantization of complex envelope of the narrow-band signal. DWM resistance against intersymbol interference, multiplicative and additive interferences are provided accordingly by means of: 1) OFDM-like forming the narrow-band channels, 2) quantization step adaptation in the transmitter and receiver, and 3) spreading of one bit DWM energy along L samples. The algorithm allows realization of automatic identification of radiotelephone transmissions without replacing standard radio installation and changing operational radiotelephony procedures. © 2010 IEEE.

We have performed a molecular dynamics study in order to verify the assumption that saturated hydrocarbons can be characterized by generalized Hook's law using the fourth rank tensor of elastic constants. In this study normal paraffins were treated as crystals of hexagonal symmetry. Thus, we obtained original numerical values of Young's modulus and Poisson's ratio in both anisotropic and isotropic planes and the values of the shear modulus at three different temperatures.Negative Poisson's ratio of n-paraffins is of a particular interest. The author believes that auxetic behavior of saturated hydrocarbons is the result of their liquid-crystalline nature. Another remarkable point is the non-linear elasticity of n-paraffins detected in a wide temperature range. This provides an additional experimental confirmation of the phase transition process of hydrocarbons earlier reported in scientific works.We have shown that the matrix of elasticity of a particular heavy petroleum product can be estimated using the elastic parameters of the n-paraffins obtained. The numerical values of five independent elastic constants are directly proportional to the composition of a heavy petroleum product. The simplified representation of the composition can be defined by a few saturated hydrocarbons with different carbon numbers.The numerical results obtained in this research may be useful for those interested in heavy petroleum fractions rheology as well as those who perform numerical studies in petroleum hydrodynamics and acoustics. © 2014 Elsevier B.V.

The paper presents a solution of the problem of determining the stress state in an elastic isotropic half-space with a crack intersecting its boundary under harmonic longitudinal shear vibrations. The vibrations are excited by a regular action of a harmonic shear load on the crack shores. The solution method is based on the use of the discontinuous solution of the Helmholtz equation, which allows one to reduce the original problem to a singular integro-differential equation for the unknown jump of the displacement on the crack surface. The solution of this equation is complicated by the existence of a fixed singularity of its kernel. Therefore, one of the main results is the development of an efficient approximate method for solving such equations, which takes into account the true asymptotics of the unknown function. The latter allows one to obtain a high-precision approximate formula for calculating the stress intensity factor. © 2013 Allerton Press, Inc.

The 'Joint Optimization of Radar Waveforms' and 'Filtering Target Returns from Interfering Radar Reflections (Clutter)' methods are considered. The optimization is provided under additional range resolution power constraints and signal-to-noise ratio loss constraints. There are different constraints on duration and bandwidth for the optimized waveform and filter as well. Optimized waveforms and filters create sets with group-complementary properties, which are extensions of Golay complementary sequence concept, expanded over the mismatched case. © 2015 IEEE.

We obtain the explicit solution of a nonaxisymmetric problem of delaminated circular interface inclusion in a piecewise homogeneous transversely isotropic space under the action of arbitrary loads. We establish the asymptotics of solutions and deduce expressions for the generalized stress intensity factors on the boundary of the inclusion and also their values for some combinations of transversely isotropic materials. © 2014, Springer Science+Business Media New York.

The novel algorithm of DWM forming is designed on the base of scalar product quantization for vectors of audio signal frequency coefficients and pseudorandom sequence. Adaptation of step quantization and multichannel processing using OFDM technology provide DWM robustness against amplitude distortions, filtering and digit-analog-digit transformation. Possibility of flexible choosing of algorithm parameters allows realizing DWM robustness-imperceptibility trade-off for construction of practical schemes of information security. © 2013 CriMiCo'2013 Organising Committee, CrSTC.
