Modelling the light curves of Fermi LAT millisecond pulsars
(South African Institute of Physics, 2014)
There are 40 millisecond pulsars (MSPs) in the second pulsar catalogue of the Fermi Large Area Telescope (LAT). This pulsar subpopulation is unique owing to their relatively small magnetospheres. This may result in radio ...
Received power prediction of a terrestrial TV broadcasting transmitter using ordinary kriging interpolation
(SATNAC, 2014)
Radio Environment Mapping (REM)
provides information useful for many different
applications in the telecommunications field. In this
paper, the authors evaluate the ability of ordinary
kriging (OK) to produce a REM ...
Freight tracking cost analysis to improve logistics management operations
(SATNAC, 2014)
The cross-border freight industry suffers from inefficiencies
that can be addressed by implementing technology
based systems. Inefficiencies cause time delays at amongst others
border posts and weigh stations that in ...
Digital video shot boundary detector investigation
(SATNAC, 2014)
Many algorithms have been proposed and evaluated
for the detection of shot boundaries in digital video.
Although these techniques have been verified, there remains
a lack of standardised data to classify which techniques
are ...
The use of an information security vocabulary test to assess information security awareness: an exploratory study
(Centre for Security, Communications and Network Research (CSCAN), 2010)
The dependence on human involvement and human behavior to protect information assets
makes it necessary to have an information security awareness program to make people aware
of their roles and responsibilities towards ...
An assessment of the role of cultural factors in information security awareness
(IEEE, 2011)
An information security awareness program is regarded as an important instrument in the protection of information assets. In this study, the traditional approach to an information security awareness program is extended to ...
Experimentelle und theoretische Untersuchungen zum Rotorabsturz in Wälzlager
(2011)
Um eine Auslegung von Fanglagern durchzuführen
ist es notwendig, die Belastungen dieser
in den zu erwartenden Abwurfszenarien zu
kennen. Da so ein chaotischer Vorgang schwer
analytisch berechnet werden kann, ist es ...
Validierung eines Gleitfanglagermodells durch Abwurfversuche
(LCM GmbH, 2012)
Der Betrieb magnetgelagerter Maschinen er-fordert grundsätzlich den Einsatz von Fangla-gern. Diese nehmen den Rotor bei Maschinen-stillstand, bei abgeschalteter Magnetlagerung oder bei Magnetlagerversagen auf. Es wird ...
The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)
Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important
aspect of AMB safety. A model for this rotor behavior was developed and was used to
characterize the severity of rotor delevitation ...
