Faster Joins , Self - Joins and

We propose a new algorithm, called Stripe-join, for performing a join given a join index. Stripe-join is inspired by an algorithm called \Jive-join" developed by Li and Ross. Stripe-join makes a single sequential pass through each input relation, in addition to one pass through the join index and two passes through a set of temporary les that contain tuple identiiers but no input tuples. Stripe...

Electronic and magnetic materials are the central focus of our group's research. We study a wide variety of types of materials such as nanostructures, thin films, multilayered heterostructures, and bulk polycrystals and single crystals. We have interests in several areas including the interplay between electronic transport and magnetism in novel materials, and the study of interfaces between di...

A Comparative Study of AMS Circuit Simulation in VHDL-AMS and SystemC-AMS

Mixed-Signal extensions to VHDL and SystemC languages have been developed in order to provide a unifying environment for the modeling and verification of AMS designs at different levels of abstraction. In this paper, we model the behavior of a set of benchmark designs in VHDL-AMS and SystemC-AMS and compare the simulation run-time with the low level HSPICE simulation run-time. The various exper...
