A parametric study was carried out to study the behavior of offshore anchor piles under mooring forces in dense sand using a three dimensional (3-D) finite element model (FEM). The Mohr–Coulomb plastic model has been used to model the soil, and has been calibrated based on the centrifuge tests discussed in a Ph.D. thesis (published by Ramadan in 2011). The selection of model parameters and comp...

The C-to-U editing of apolipoprotein B (apo-B) mRNA is catalyzed by a multiprotein complex that recognizes an 11-nucleotide mooring sequence downstream of the editing site. The catalytic subunit of the editing enzyme, apobec-1, has cytidine deaminase activity but requires additional unidentified proteins to edit apo-B mRNA. We purified a 65-kDa protein that functionally complements apobec-1 and...

In this paper, we develop a new finite element model for a cable suspended in water. Global existence and uniqueness of solutions of the truncated system is shown for a slightly simplified equation describing the motion of a cable having negligible added mass and supported by fixed end-points. Based on this, along with well known results on local existence and uniqueness of solutions for symmet...

The main objective of the joint Nansen Legacy and A-TWAIN/SIOS-InfraNor mooring service cruise was recovery deployment projects’ moorings in Barents Sea north Svalbard. Additionally, CTD stations with water sampling for both projects, a Seaglider Legacy, recoveries deployments partner projects were planned depending on sea ice conditions time available.

Sound speed in the oceans depends on temperature, salinity, and pressure and has large seasonal and spatial variations. Since temperature and salinity variations are large compared to pressure, we studied the relative importance of these two parameters on sound speed by analyzing the hourly profiles for one year (16 October 1994 – 22 October 1995) up to 250 m depth from the Woods Hole Oceanogra...

Complex sensitive motions have been observed in ocean mooring systems consisting of nonlinear mooring geometries. These physical systems can be modeled as a system of first-order nonlinear ordinary differential equations, taking into account geometric nonlinearities in the restoring force, quadratic viscous drag, and harmonic excitation. This study examines the controllability of these systems ...

While previous research on software ecosystems (SECO) mostly focused on SECO providers or software developers, recent studies have begun to analyze the user perspective and try to explain switching behavior. However, SECOs are complex and consist of several components. Since current switching theories do not fully account for these complex structures, these need to be adapted. We expand the pus...
