Ephemerides in high medieval Europe: The textual evidence

open access: yes, 2021
A common aspect of the practice-oriented side of pre- and early modern mathematical astronomy was the computation of ephemerides, i.e., tables that displayed the daily positions of the planets in a synoptic and calendrical format.

Formal Development of a Total Order Broadcast for Distributed Transactions using Event-B

open access: yes, 2009
. In a replicated database system, copies of the database are kept across several sites for fault-tolerance and availability. Data access in such systems is usually done within a transactional framework.

A communication model of broadcast in wormhole-routed networks on-chip [PDF]

open access: yes, 2009
This paper presents a novel analytical model to compute communication latency of broadcast as the most fundamental collective communication operation. The novelty of the model lies in its ability to predict the broadcast communication latency in wormhole-

Experiments for improved positioning by means of integrated Doppler satellite observations and the NNSS broadcast ephemeris [PDF]

open access: yes, 1977
An effort to improve station position recovery using broadcast ephemeris in Doppler data reduction was studied. A comparison of precise and broadcast ephemerides, treating the former as the standard, yielded information about the state disturbance that ...
