Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

The Higgs faotopization of a strong map between matroids on a fixed set is that factorization into elementary naps in which each matroid is the Higgs lift of its successor. This factorization is characterized by properties of the modular filters which induce the elementary maps of the factorizations in two different ways. It is also sho~m to be minimal in a natural order on factorizations arisi...

— We prove that if a closed aspherical Riemannian 3-manifold M contains a 2-flat, then there exists a free abelian subgroup of rank two in π1(M). Under some restrictions on the topology of M we prove the existence of an immersed incompressible flat torus in M . This generalizes results which were previously known for manifolds of nonpositive curvature. RÉSUMÉ. — Nous prouvons que si une variété...

[1] Shallow microtidal basins are characterized by extensive areas of tidal flats that lie within specific ranges of elevation. These landforms are inherently flat and their evolution strongly depends on the balance between sedimentary and erosive processes. Here we present a stochastic point model for tidal flat evolution to study the influence of tidal currents and wind waves on tidal flat eq...

Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...

The establishment of Malaysia cadastral system is to monitor matters of land especially the land ownership. The system is setup to ensure consistency in cadastral information that comes from cadastral survey and cadastral land registration. In general, the cadastral survey and cadastral land registration are managed by Department of Survey and Mapping Malaysia (DSMM) and Land Offices (LO) respe...

In this paper, we introduce subspace-frequently hypercyclic operators. We show that these operators are subspace-hypercyclic and there are subspace-hypercyclic  operators that are not subspace-frequently hypercyclic. There is a criterion like to subspace-hypercyclicity criterion that implies subspace-frequent hypercyclicity and if an operator $T$ satisfies this criterion, then $Toplus T$ is sub...

A variety of file replication and replacement algorithms were proposed for the Data Grids in the literature. On the other hand, real-time Grid applications are emerging in many disciplines of science and engineering. Thus, it is natural to ask about the realtime performance of these file replication and replacement algorithms. Based on this motivation, in this study, the performance of three re...

Diving into parenthood is never easy, but for common murres (Uria aalge) some positively prudent parenting is required. These birds have to decide whether they care more about the chicks they have got or about having additional chicks in the future. Anne Storey and her colleagues were able to measure the physiological tell-tale signs of this balancing act both when food is scarce and when food ...
