Effect of tunnel size on support pressure
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1996This technical note reviews existing empirical approaches for estimating support pressure and studying the effect of tunnel size on support pressure, and discusses a concept proposed by RK Goel for emphasising the effect of tunnel size on support pressure.

Catalysis by Supported Size-Selected Clusters
2009The use of size-selected metal clusters as model catalysts opens up many exciting new possibilities for the study of size-dependent catalysis. By supporting these size-selected clusters on planar thin-film or single-crystal metal oxide substrates, a variety of analysis techniques can be employed to examine them in detail in an effort to understand how ...

On the Support Size of Null Designs of Finite Ranked Posets
Combinatorica, 1999Given two ranks \(t \leq k\) of a finite ranked partially ordered set \(P\), it is possible to define a \(0,1\) matrix, called adjacency matrix, with columns indexed by the elements of rank \(k\) and the rows indexed by the elements of rank \(t\). The kernel of this matrix forms a space.

Support sizes of indecomposable threefold triple systems
2001A \(\lambda\)-fold triple system is a pair \(T=(V,\text{QTR}{\mathcal B})\), \(\text{QTR}{\mathcal B}\) being a collection of 3-subsets of \(V,\) so that each \(2-\)subset of \(V\) occurs in exactly \(\lambda \) block of \(\text{QTR} {\mathcal B}\).

The effects of support size on the vibration of the point supported plate
2011The fundamental frequencies of plate are important for engineering designs. Free vibration characteristics of isotropic rectangular plates with point, spring and viscoelastic supports have been studied by several researchers. However, the practical implementation of these boundary conditions in application is not at all trivial.

Influence of Particle Size and Support on the Catalytic Properties of Supported Rhodium
1982Resume Ce travail concerne les proprietes catalytiques du rhodium supporte sur alumine ou sur silice vis-a-vis de l'hydrogenolyse du methylcyclopentane a 220°C et de l'empoisonnement de l'hydrogenation du benzene par le thiophene a 80°C. Dans ces deux cas apparaissent des effets de taille de particule et un effet du support est observe a grande ...

The support sizes of MPT(v, 3)
2006The support size SS(v, 3) of a maximum packing of triples of order v and index 3, MPT(v, 3), is the number of distinct triples appearing in it. We establish strong necessary conditions on the spectrum of support sizes for a MPT (v, 3) and, for some subset of SS(v, 3), we find a sufficient condition.
