Instant restore after a media failure
Caetano Sauer, Goetz Graefe, Theo Härder
Media failures usually leave database systems unavailable for several hours until recovery is complete, especially in applications with large devices and high transaction volume. P…
How Particles can Emerge in a Relativistic Version of Bohmian Quantum Field Theory: Part 2 - Fermions
T. Mark Harder
It is shown how Fermionic material particles can emerge from a covariant formulation of the de Broglie-Bohm theory. Material particles are continuous fields, formed as the eigenval…
How particles can emerge in a relativistic version of Bohmian Quantum Field Theory
T. Mark Harder
It is shown how bosonic material particles can emerge from a covariant formulation of de Broglie-Bohm theory. The formulation is based on the work of Nikolic. Material particles ar…
A novel recovery mechanism enabling fine-granularity locking and fast, REDO-only recovery
Caetano Sauer, Theo Härder
We present a series of novel techniques and algorithms for transaction commit, logging, recovery, and propagation control. In combination, they provide a recovery component that ma…
Energy and Performance-Can a Wimpy-Node Cluster Challenge a Brawny Server?
Daniel Schall, Theo Härder
Traditional DBMS servers are usually over-provisioned for most of their daily workloads and, because they do not show good energy proportionality, waste a lot of energy while under…
Dynamic Physiological Partitioning on a Shared-nothing Database Cluster
Daniel Schall, Theo Härder
Traditional DBMS servers are usually over-provisioned for most of their daily workloads and, because they do not show good-enough energy proportionality, waste a lot of energy whil…
Constructive Comments on QED2 in Curved Spacetime - I
T. Mark Harder, Thomas K. DeLillo
In this paper an axiomatic formulation of the Schwinger Model in curved spacetime is considered. The mathematical approach utilized is that specified by Hollands and Wald in [1]. W…
Update XML Views
Jixue Liu, Chengfei Liu, Theo Haerder +1
View update is the problem of translating an update to a view to some updates to the source data of the view. In this paper, we show the factors determining XML view update transla…
An Exact Solution to the Yukawa System in Four Dimensions
T. Mark Harder, Thomas K. DeLillo
An exact, closed form solution to the scalar Yukawa system in four dimensions is presented. The formalism is used to state and prove a theorem on the initial value problem. The met…
