ER modelling from first relational principles
Entity-Relationship modelling is a popular technique for data modelling. Despite its popularity and wide spread use, it lacks a firm semantic foundation. We propose a translation of an ER-model into relation algebra, suggesting that this kind of algebra does provide suitable mechanisms for establishing a formal semantics of Entity-Relationship modelling. The work reported on here deals first wi...
متن کاملAn Atlas for Interpreting Γ-ray Pulsar Light Curves
We have simulated a population of young spin-powered pulsars and computed the beaming pattern and light curves for the three main geometrical models: polar cap emission, two-pole caustic (“slot gap”) emission and outer magnetosphere emission. The light curve shapes depend sensitively on the magnetic inclination α and viewing angle ζ. We present the results as maps of observables such as peak mu...
متن کاملVery High Energy Gamma Rays from the Vela Pulsar/nebula
We have observed the Vela pulsar region at TeV energies using the 3.8 m imaging Čerenkov telescope near Woomera, South Australia every year since 1992. This is the first concerted search for pulsed and unpulsed emission from the Vela region, and the imaging technique also allows the location of the emission within the field of view to be examined. A significant excess of gamma-ray-like events i...
متن کاملVery High Energy Gamma Rays from the Vela Pulsar Direction
We have observed the Vela pulsar region at TeV energies using the 3.8 m imaging Čerenkov telescope near Woomera, South Australia between January 1993 and March 1995. Evidence of an unpulsed gamma-ray signal has been detected at the 5.8 σ level. The detected gamma-ray flux is (2.9± 0.5± 0.4)× 10 photons cm sec above 2.5± 1.0 TeV and the signal is consistent with steady emission over the two year...
متن کاملPolarization of high-energy emissions from the Crab pulsar
We investigate polarization of high-energy emissions from the Crab pulsar in the frame work of the outer gap accelerator, following previous works of Cheng and coworkers. The recent version of the outer gap, which extends from inside the null charge surface to the light cylinder, is used for examining the synchrotron radiations from the secondary and the tertiary pairs, which are produced outsi...
