Analytical model for shear strength estimation of reinforced concrete beam-column joints
(Elsevier Ltd, 2018)
A model capable of predicting the shear response of beam-column joints subjected to seismic actions is presented. The analytical model, originally developed for walls and based on a simple physical formulation, is adapted. ...

The Ring: Worst-case Optimal Joins in Graph Databases using (Almost) No Extra Space
(2024)
We present an indexing scheme for triple-based graphs that supports join queries in worst-case optimal (wco) time within compact space. This scheme, called a ring, regards each triple as a cyclic string of length 3. Each ...
