Numerical models of Saturn's long-lived anticyclones

Numerical Model ~f Long-Lived Jabvian Vortices

A nonlinear numerical model of long-lived Jovian vortices has been constructed. We assume that the measured zonal velocity profile i(y) extends into the adiabatic interior, but that the eddies and large oval structures are confined to a shallow stably stratified upper layer. Each vortex is stationary with respect to the shear flow & ( y ) at a critical latitude y , that is close to the latitude...

Recovery in Distributed Extended Long-lived Transaction Models

This paper addresses the recovery and the rollback problem in distributed collaborative transactions. We propose a solution to the problem in a generalized ARIES [9] framework. We modified its existing data structures and provided additional data structures for recovery of distributed extended long-lived transactions. In the proposed model the transactions communicate and collaborate only by ex...

Long-Lived Broadcast Encryption

In a broadcast encryption scheme, digital content is encrypted to ensure that only privileged users can recover the content from the encrypted broadcast. Key material is usually held in a “tamperresistant,” replaceable, smartcard. A coalition of users may attack such a system by breaking their smartcards open, extracting the keys, and building “pirate decoders” based on the decryption keys they...

Fast, Long-Lived Renaming

We consider wait-free solutions to the renaming problem for shared-memory multiprocessing systems [3, 5]. In the renaming problem, processes are required to choose new names in order to reduce the size of their name space. Previous solutions to the renaming problem have time complexity that is dependent on the size of the original name space, and allow processes to acquire names only once. In t...
