Introduction Cable stayed bridges are a feasible choice for middle length spans and can be also an alternative to suspension bridges in the range of 1000 m spans. In the last three years, cable stayed bridges having more than 1 km span have been built in China (Sutong Bridge, 1088 m and Stonecutters Bridge, 1018 km). The increasing in length implies higher aeroelastic interaction with wind acti...

Ultrafast UV-vibrational spectroscopy was used to investigate how vibrational excitation of the bridge changes photoinduced electron transfer between donor (dimethylaniline) and acceptor (anthracene) moieties bridged by a guanosine-cytidine base pair (GC). The charge-separated (CS) state yield is found to be lowered by high-frequency bridge mode excitation. The effect is linked to a dynamic mod...

The photoinduced intramolecular electron transfer in five donor-bridge-acceptor systems is studied by analysing the field dependence of chemically induced dynamic nuclear polarisation. The exchange interaction, J, in the charge separated state of these complexes is determined as function spacer length. J has positive sign and shows an exponential decrease with increasing bridge length. By compa...

Water molecules play a crucial role in mediating the interaction between a ligand and a macromolecule. The solvent environment around such biomolecule controls their structure and plays important role in protein-ligand interactions. An understanding of the nature and role of these water molecules in the active site of a protein could greatly increase the efficiency of rational drug design appro...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

UML has become a de facto standard in software industry, and many attempts to bridge the gap between software engineering (SE) and human-computer interaction (HCI) have extended UML to incorporate HCI elements and concerns into the software development process. However, by adopting a representation which springs mainly from a single disciplinary field, communication among the design team member...

The structure and dynamics of linear monodisperse polyethylene (PE) melts (C160H322 and C440H882) containing homogeneously distributed spherical nanoparticles were investigated. The PE chains were simulated using a coarse-grained model and a Monte Carlo algorithm. Two variables were considered: (i) the wall-to-wall distance between particles d and (ii) the interaction energy between monomers an...

Deep ownership types gives a strong notion of aggregate by enforcing the so-called owners-as-dominators property: every path from a system root to an object must pass through its owner. Consequently, encapsulated aggregates must have a single bridge object that mediates all external interaction with its internal objects. In this paper, we present an extension of deep ownership that relaxes the ...
