In this paper, a new combined form of Glass Fiber Reinforced Plastic (GFRP) column and steel fiber mortar reinforced damaged Concrete (RC) is proposed. With the help ABAQUS finite element software, model GFRP tube RC established. Based on experiment strengthening column, parameters such as winding angle tube, strength section loading mode are studied by numerical simulation. The results show th...

A high performance liquid chromatography (HPLC) method was established for the determination of two acrylate substances in environmental water. The optimal chromatographic conditions were determined via exploring effects column, mobile phase, column temperature, flow rate, detection wavelength and other factors on separation effect substances. Finally, effective methyl methacrylate isopropyl re...

In the Hudson Canyon experiment, a sound source KRAKENWudson Canyon experiment moved at a constant depth in 73 m of water while transmitting four tonals. The signal was received on a vertical array of hydrophones that spanned the water column. The data set from this experiment has become a standard test case for studying source tracking using matched-field processing. As part of that process it...

In a 2.5-year-long environmental engineering experiment in the By Fjord, surface water was pumped into the deepwater where the frequency of deepwater renewals increased by a factor of 10. During the experiment, the deepwater became long-term oxic, and nitrate became the dominating dissolved inorganic nitrogen component. The amount of phosphate in the water column decreased by a factor of 5 due ...

An experiment was developed using aeration of water for demonstrating the phenomenon of mass transfer. The demonstration was designed to provide both conceptual and practical insight of the mass transfer process. A bubble column fitted with a sieve tray was used to carry out the experiment. The air flow rate and hole size of the sieve tray were varied. Mass transfer coefficient was obtained fro...

1986). In contrast, an apparent disagreement may be produced by applying an equilibrium model to data This study reconciles an apparent inconsistency between the dialthough sorption equilibrium was not reached within methylphthalate (DMP) batch and column data reported in the literature. Some researchers found that retardation coefficients obtained the time scale of the batch or column experime...

The wave propagation and power deposition inside outside the blue-core helicon plasma are computed, together with their transitional behaviours prior to after formation. Computations refer experiments on CSDX (controlled shear decorrelation experiment) (Thakur et al., Plasma Sources Science Technology 23: 044,006, 2014 Thakur IEEE Transactions 43: 2754–2759, 2015). It is found that radial profi...

This paper is intended to examine the efficiency of utilizing FRP composite material with an externally bonded technique in enhancing behavior damaged B-C joints and controlling their failure mode using NLFEA approach. At first, modeled Beam-Column joint was validated as per previously-attained experimentally-attained results. Later, model widened experiment impact axial-column load concrete co...

In this note we show how the entries of a data matrix can be approximated by a sum of row effects, column effects and interaction terms in a robust way using a weighted L1 estimator. We discuss an algorithm to compute this fit, and show by a simulation experiment and an example that the proposed method can be a useful tool in exploring data matrices. Moreover, a robust biplot is produced as a b...
