Size effects in the fatigue behavior of welded tubular bridge joints

Tubular space trusses for bridge applications use thick-walled tubes. The reduction in fatigue resistance due to geometrical size effects is thus an important issue. In order to carry out a thorough study, both fatigue tests on large-scale specimens and ad ...

Do Abatement Quotas Lead to More Successful Climate Coaliltions?

Juan Carlos Altamirano Cabrera

This paper studies the effect of different treaty designs on the success of international environmental agreements (IEAs). We analyze the standard assumption of an efficient abatement scheme and three uniform abatement quota schemes. Apart from analytical ...

Mapping Personal Trip OD from Probe Data

Edward Chung

The paper analyses the expected value of OD volumes from probe with fixed error, error that is proportional to zone size and inversely proportional to zone size. To add realism to the analysis, real trip ODs in the Tokyo Metropolitan Region are synthesised ...

Dislocation-void interaction in Fe: a comparison between molecular dynamics and dislocation dynamics

Seyed Masood Hafez Haghighat

Multiscale modeling, including molecular dynamics (MD) and discrete dislocation dynamics (DDD) methods, appears as a significant tool for the description of plasticity and mechanical properties of materials. This research concerns the influence of irradiat ...

Probing the validity of the Derjaguin approximation for heterogeneous colloidal particles

Ramon Pericet Camara, Michal Borkovec

The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...

The Impact of Surplus Sharing on the Stability of International Climate Agreements

Juan Carlos Altamirano Cabrera

This paper analyses stability of coalitions for greenhouse gas abatement under different sharing rules applied to the gains from cooperation. We use a 12-region model to examine internal and external stability of coalitions. We determine and compare stable ...

A cross-layer design of wireless ad-hoc networks

We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...

Self-similar density turbulence in the TCV tokamak scrape-off layer

Jonathan Graves, Richard Pitts, Jan Horacek

Plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak exhibit statistical properties which are universal across a broad range of discharge conditions. Electron density fluctuations, from just inside the magnetic separatrix to the plasma-wall ...

On Average Throughput Benefits and Alphabet Size in Network Coding

Christina Fragouli, Emina Soljanin

e analyze a special class of configurations with h sources and N receivers to demonstrate the throughput benefits of network coding and deterministic code design. We show that the throughput benefits network coding offers can increase proportionally to \sq ...

SOI Hall sensor based solid state meter for power and energy measurements

Maher Kayal

Growing demand for the solid state meters for power and energy measurement leads to the fully integrated Hall sensor based microsystem solutions. In this paper we describe fully integrated SOI Hall sensor based microsystem for power and energy measurements ...
