2000 Journal of constructional steel research  
As a result of a world-wide intensive research activity, a new design concept for structural moment resistant joints has been suggested and implemented in design codes.  ...  As a matter of fact, because of the high number of past and ongoing researches, reports and papers devoted to this topic, an exhaustive list of all these works could not be established in a limited number  ...  One of the main aspects which would focus the attention in the future will be the transfer of these new concepts to practice through appropriate actions (e.g. seminars) and education efforts.  ...

On the classification of 6D SCFTs and generalized ADE orbifolds

We obtain all other SCFTs by bringing in a number of E-string theories and/or decorating curves in the base by non-minimal gauge algebras.  ...  When G is a subgroup of SU(2), all discrete subgroups are allowed, and this leads to the familiar ADE classification of (2,0) SCFTs.  ...  , to obtain a new surface B k+1 and a blowdown map ρ : B k+1 → B k .  ...

Extensions of Invariant Signatures for Object Recognition

Daniel J. Hoff, Peter J. Olver
2012 Journal of Mathematical Imaging and Vision  
The value of the method lies in its compromise between local and global identifying properties, thereby allowing us to distinguish non-congruent curves whose Euclidean signatures have identical trace.  ...  A refinement of the method of differential invariant signatures for object recognition is presented.  ...  In this section, we apply the results of Section 2 to devise a practical algorithm for curve comparison and classification. Some preliminary applications will be described in the following section.  ...
