In bridge engineering, maintenance strategies and thus budgetary demands are highly influenced by construction type and quality of design. Nowadays bridge owners and planners tend to include life-cycle cost analyses in their decision processes regarding the overall design trying to optimize structural reliability and durability within financial constraints. Smart permanent and short term monitoring can reduce the associated risk of new design concepts by observing the performance of structural components during prescribed time periods. The objectives of this paper are the discussion and analysis of influence line or influence field approaches in terms of (a) an efficient incorporation of monitoring information in the structural performance assessment, (b) an efficient characterization of performance indicators for the assessment of structures, (c) the ability of optimizing the positions of sensors of a monitoring system, and (d) the ability of checking the robustness of the monitoring systems applied to a structure. The proposed influence line- model correction approach has been applied to an integrative monitoring system that has been installed for the performance assessment of an existing three-span jointless bridge.
Extended MHD simulation of resonant magnetic perturbations
Strauss, H.R.,Sugiyama, L.,Park, G.Y.,Chang, C.S.,Ku, S.,Joseph, I. International Atomic Energy Agency 2009 Nuclear fusion Vol.49 No.5
<P>Resonant magnetic perturbations (RMPs) have been found effective in suppressing edge localized modes (ELMs) in the DIII-D experiment (Evans <I>et al</I> 2006 <I>Phys. Plasmas</I> <B>13</B> 056121, Moyer <I>et al</I> 2005 <I>Phys. Plasmas</I> <B>12</B> 056119). Simulations with the M3D initial value code indicate that plasma rotation, due to an MHD toroidal rotation or to two-fluid drifts, has an essential effect on the RMP. When the flow is below a threshold, the RMP field can couple to a resistive mode with a helical structure, different from the usual ELM, that amplifies the non-axisymmetric field. The magnetic field becomes stochastic in the outer part of the plasma, causing density and temperature loss. At higher rotation speed, the resistive mode is stabilized and the applied RMP is screened from the plasma, so that the stochastic magnetic layer is thinner and the temperature remains similar to the initial unperturbed state. The rotational flow effects, along with the remnants of the screened RMP, cause a density loss which extends into the plasma core. The two-fluid model contains intrinsic drift motion and axisymmetric toroidal rotation may not be needed to screen the RMP nor stabilize the resistive mode.</P>
CA SE REPORT : Recurrent and Troublesome Variceal Bleeding from Parastomal Caput Medusae
( Claire Strauss ),( Malathi Sivakkolunthu ),( Abraham A. Ayantunde ) 대한소화기학회 2014 대한소화기학회지 Vol.64 No.5
Variceal bleeding is common in chronic liver disease and is a frequent cause of acute upper gastrointestinal bleeding. The most common site of varices is the lower oesophagus but they may occur at any location where there are portosystemic anastomoses and collateral vascular formation. Location of ectopic varices at the site of enterocutaneous stomas is rare. We report on three cases of recurrent and severe bleeding from parastomal varices, requiring hospital admission. The patients had chronic liver disease but of different aetiological factors. Variceal formation results from portal hypertension due to chronic liver disease. There are various treatment options for parastomal variceal bleeding, including local, medical, and surgical interventions. Management of parastomal variceal bleeding presents a recurring and difficult problem. Bleeding may be considerable and sometimes life threatening. This diagnosis must be considered in patients with chronic liver disease presenting with stomal bleeding, even where the variceal formation may not be readily visible.

Reinforced concrete corbels are structural elements widely used in practical engineering. The complex response of these elements is described in design codes in a simplified manner. These formulations are not sufficient to show the real behavior, which, however, is an essential prerequisite for the manufacturing of numerous elements. Therefore, a deterministic and probabilistic study has been performed, which is described in this contribution. Real complex structures have been modeled by means of the finite element method supported primarily by experimental works. The main objective of this study was the detection of uncertainties effects and safety margins not captured by traditional codes. This aim could be fulfilled by statistical considerations applied to the investigated structures. The probabilistic study is based on advanced Monte Carlo simulation techniques and sophisticated nonlinear finite element formulations.
Nonlinear probabilistic shear panel analysis using advanced sampling techniques

The shear behaviour of reinforced concrete members has been studied over the past decades by various researchers, and it can be simulated by analysing shear panel elements which has been regarded as a basic element of reinforced concrete members subjected to in-plane biaxial stresses. Despite various experimental studies on shear panel element which have been conducted so far, there are still a lot of uncertainties related to what influencing factors govern the shear behaviour and affect failure mechanism in reinforced concrete members. To identify the uncertainties, a finite element analysis can be used, which enables to investigate the impact of specific variables such as the reinforcement ratio, the shear retention factor, and the material characteristics including aggregate interlock, tension stiffening, compressive softening, and shear behaviour at the crack surface. In this study, a non-linear probabilistic analysis was conducted on reinforced concrete panels using a finite element method optimized for reinforced concrete members and advanced sampling techniques so that probabilistic analysis can be performed effectively. Consequently, this study figures out what analysis methodology and input parameters have the most influence on shear behaviour of reinforced concrete panels.
