As special equipment for storing energy, the safety performance of liquified natural gas (LNG) storage tanks under earthquake action is extremely important. To study dynamic characteristics large-scale LNG tank structure and response action, shaking table test numerical simulation analysis model are carried out. The results demonstrate that vibration frequency significantly reduced after isolat...

Conventional energy sources are fast depleting due to poor conservation practises and excessive usage while the world’s energy demands are growing by minute. Additionally, the cost of producing conventional energy is rising also leading to an increase in harmful environmental pollution. Hence, there is a need to look at alternative energy sources such as sun, water and wind. Photovoltaic (PV) i...

This paper proposes the adaptation of Support Vector Data Description (SVDD) to the multiple kernel case (MK-SVDD), based on SimpleMKL. It also introduces a variant called Slim-MK-SVDD that is able to produce a tighter frontier around the data. For the sake of comparison, the equivalent methods are also developed for One-Class SVM, known to be very similar to SVDD for certain shapes of kernels....

Impact of the satellite data assimilation on the naval undersea capability is investigated using the ocean hydrographic data without and with satellite data assimilation. The former is the Navy’s Global Digital Environmental Model (GDEM) providing the monthly mean; and the latter is the Modular Ocean Data Assimilation System (MODAS) proving the synoptic data. The two environmental datasets are ...

Over the past two decades, aircraft crashworthiness has seen major developments, mainly with modern computing systems and commercial finite element (FE) codes. The structure material have been designed to absorb more kinetic energy ensure enough safety during a controlled crash condition. However, fuselage section an onboard auxiliary fuel tank requires special arrangements, since inclined stru...

By collecting and organizing historical data typical model characteristics, hydrogen energy storage system (HESS)-based power-to-gas (P2G) gas-to-power systems are developed using Simulink. The transfer mechanisms numerical modeling methods of the proposed studied in detail. integrated HESS covers following components: alkaline electrolyzer (AE), high-pressure tank with compressor (CM & H2 tank...

This paper deals with Mixed Logical Dynamical (MLD) approach. It allows to model the hybrid systems involved continuous, discrete dynamics and constraints. The changes or the switches which may appear over such dynamics are modelled by using the auxiliary variables take into account the interconnections. The applicability of this approach is illustrated by the modelling of the two tank system. ...

This paper, focuses on model predictive control (MPC) problem with fault-tolerance capabilities is formulated within the hybrid systems framework In particular Mixed Logical Dynamical (MLD) approach is considered. It allows to model the hybrid systems involved continuous, discrete dynamics and constraints. The changes or the switches which may appear over such dynamics are modeled by using the ...

The solar-assisted electric boiler water heating systems adopted in student apartments at universities have some shortcomings, such as unsuitable system designs, unstable supply temperature, and excessive power consumption. As discussed this paper, the hot was reformed, two with same building area, solar collector similar consumption were selected to be used comparative experiments. auxiliary h...

Designs of composite laminates are investigated for hydrogen tanks in cryogenic environments. Large residual strains, which can develop due to thermal mismatch between matrix and Ž bers, result in matrix cracking at cryogenic temperatures and increase hydrogen leakage through the tank wall. To reduce thermal mismatch, ply angles need to be close to each other, but this leads to a substantial we...
