Designing efficient grid structures considering structural imperfection sensitivity

Imperfection-sensitivity and Catastrophe Theory

the effect of initial geometric imperfection on the load bearing capacity of double layer grid space structures

the existence of some geometrically imperfect members, like initial curvature in a double layer space structures with hundreds or thousands of members is almost inevitable. these imperfections give rise to loss of load bearing capacity of double layer space structures. to evaluate the effect of initial member imperfection on load bearing capacity of double layer space structures and their failu...

Distribution Grid Planning Considering Smart Grid Technologies

Connection of distributed generation (DG) units, energy storages, and new loads into low voltage (LV) grids leads to a constrained operation of the grids. Consequently, voltage limits violation and overloading of grid assets occur more frequently. To tackle these issues, distribution system operators (DSO) still employ traditional techniques in planning distribution grids to increase grid hosti...

Efficient Data Structures for Range Searching on a Grid

We consider the 2-dimensional range searching problem in the case where all points lie on an integer grid. A new data structure is presented that solves range queries on a U * U grid in O( k + log log U) time using O( n log n) storage, where n is the number of points and k the number of reported answers. Although the query time is very good the preprocessing time of this method is very high. A ...

Designing Grid Tag Libraries and Grid Beans

We present a detailed description of the implementation of a library of Grid tag libraries and Grid beans for Grid Web portal development. Grid tags provide Java Server Faces (JSF) custom components for Grid services. They enable the definition of attributes to the Grid service parameters in a dynamic way embedded into JSF view pages. In addition, Grid beans provide client proxies to the Grid s...
