The Øresund Bridge opened in July 2000. It is the most striking part of the fixed link across the Øresund connecting Copenhagen (Denmark) and Malmø (Sweden), which further includes a tunnel and an artificial island. The bridge is equipped with a PC-based continuous monitoring system, capable of measuring both static and dynamic quantities such as temperatures, wind characteristics, air humidity...

The ability to create connections between previously incompatible software is the motivation for the work of this dissertation. We focus on devising a paradigm for interoperability between software components, a popular and often used software methodology, while making the practical concerns of this endeavor our main driving force. Component software interoperability is the ability for two or m...

A class A of graphs is called weakly addable (or bridge-addable) if for any G ∈ A and any two distinct components C1 and C2 in G, any graph that can be obtained by adding an edge between C1 and C2 is also in A. McDiarmid, Steger and Welsh conjectured in [6] that a graph chosen uniformly at random among all graphs with n vertices in a weakly addable A is connected with probability at least e−1/2...

HST ultra-violet and ground-based optical spectroscopy are presented for DI 1388, an early-type star in the Magellanic Bridge. These data have been supplemented with H I radio mapping of its environment. The spectroscopy shows interstellar components at LSR velocities of 0, 90 and 200 km s-l corresponding to the local ISM, a high velocity cloud and the Magellanic Bridge ISM, respectively. The l...

the national bridge stock of iran consists of about 330,000 bridges, of which around 50% are older than 30 years. since 2010, iran road maintenance & transportation organization has started implementing a comprehensive bridge management system in order to manage this aged stock efficiently. to predict future conditions of bridge stock, a heuristic numerical method is presented. this methodology...

Cytokinesis in somatic cells concludes with the formation of a midbody, which is abscised to form individual daughter cells. In contrast, germ cell cytokinesis results in a permanent intercellular bridge connecting the daughter cells through a large cytoplasmic channel. During spermatogenesis, proposed roles for the intercellular bridge include germ cell communication, synchronization, and chro...

This paper presents a system-based model for the fatigue assessment of old, deteriorating riveted railway bridge connections, which are built up of a number of basic components. A finite element model of a typical, short-span railway bridge is used to convert train loading into probabilistic fatigue load spectra via Monte Carlo train simulations. Uncertainties in terms of loading, resistance an...

Aerodynamic forces on bridges are commonly separated into static, self-excited, and buffeting force components. By delving into the relationships among force descriptors for static, self-excited, and buffeting components, novel perspectives are developed to unveil the subtle underlying complexities in modeling aerodynamic forces. Formulations for airfoil sections and those based on quasisteady ...

Object-oriented and relational paradigms are simply too different to bridge seamlessly. Architectures of database applications relying on three tiers need business tiers to bridge application tiers and database tiers. Business tiers hide all the complexity to convert data between the other two tiers easing this way programmers’ work. Business tiers are critical components of database applicatio...

The objective of the presented research is to develop an efficient control system for highway load effects that involves the control of various parameters including: truck weight (axle weights and axle spacing), truck load distribution on bridge girders, dynamic load, strain, stress and deflection of bridge components, and verification procedure for the minimum load carrying capacity. This stud...
