The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...

The connection between kinematics and mechanisms to algebraic constraints is well known. This work presents a general kinematics simulator that allows end users to define planar and/or spatial arrangements, even along freeform curves and surfaces. The mechanical arrangement is then converted into a set of algebraic constraints and the motion of the arrangements is computed with the aid of a mul...

((/) A complete co-operation between all the hospitals within the area, under which, while still maintaining their separate identity, they would, for all appropriate purposes, be amalgamated, in the sense of working together. (//) A limited co-operation between one or more hospitals for joint action in connection with the items set forth in (i), (ii), and (iii) above, and (c) A general working ...

An efficient numerical method is applied to a 4-D symplectic map of physical interest. Sequences of periodic orbits of very high period are obtained, whose rotation numbers approach two rationally independent ratios. Thus we are able to investigate the connection between the arrangement and stability of these orbits and the "morphology" of nearby invariant surfaces "surrounding" large regions o...

The manual of medicine which has run to the eleventh edition has proved its popularity. It deals with all the diseases described in an elementary way. It is' written in a very plain style and the arrangement is excellent. The pages dealing with tropical diseases, however, require further revision. With regard to kala-azar the statement " the mortality is said to range between 75 and 95 per cent...

We study the connection between triangulations of a type $A$ root polytope and resonance arrangement, hyperplane arrangement that shows up in surprising number contexts. Despite an elementary definition for chambers has only been computed to $n=8$ dimensional case. focus on data structures labeling chambers, such as sign vectors sets alternating trees, with aim at better understanding structure...

4 A drawing of a graph is pseudolinear if there is a pseudoline arrangement such that 5 each pseudoline contains exactly one edge of the drawing. The pseudolinear crossing 6 number c̃r(G) of a graph G is the minimum number of pairwise crossings of edges in 7 a pseudolinear drawing of G. We establish several facts on the pseudolinear crossing 8 number, including its computational complexity and i...
