title: Wireless Sensors for Dynamic Testing of a Full Scale Highway Truss: Vertical Electrodynamic White Noise Shaker Excitation

description: The truss was excited in the vertical direction with band-limited white noise to simulate ambient excitation in the field. The generated white noise, amplified using an amplifier is imposed on the truss using the electro-dynamic shaker (VG-100 from Vibration Test Systems). In all of the tests the shaker location was constant. For each of the test configurations, data was collected for multiple repetetions of the same shaker excitations. The truss was subject to band limited white noise of 0-200 Hz.

In the tests, wireless sensors are used to measure acceleration responses on the truss structure. Wireless sensors are triaxial, so x, y, and z directions are measured at the same time. Data was collected for 280 seconds at sampling frequencies of 280 Hz for the various sensor configurations.

title: Dynamic Testing of a Full Scale Highway Truss: Hammer Excitation (location 33, direction Z)

description: The truss was excited with hammer excitation to simulate impact test excitation. The modal sledge hammer (PCB 086D50) with softer red tip is used. The hammer hit location for this test was at node 33 in the Z direction. For each of the test configurations, data was collected for approximately 15 hits. 

In six of the tests, only a single direction (X, Y or Z) and either front of back panel were instrumented with 23 sensors. The seventh test was performed with the 18 sensors attached only on the lower chords front chord at six location in all 3 directions. Hence, data from this test was used to stitch together the other six tests to obtain complete 3 dimensional modal properties of the truss.The deployment of the sensors on the truss for each test is shown. In each test, the first channel was used to measure the input force excitation; modal hammer force or force transducer measurement located at the shaker and the other 23 channels were used to measure output acceleration at the nodes of the structure. Data was collected for 320 seconds at sampling frequencies of 512 Hz for the various sensor configurations.

title: Parkes observations for project P509 semester 2007APRS

description: We have been timing the very young pulsar PSR J1833-1034, recently
discovered near the center of the supernova remnant (SNR) G21.5-0.9
(Camilo et al. 2006).  With 16 months of timing data in hand we have
confirmed that the pulsar is coincident, to sub-arcsec precision, with the
centrally-peaked X-ray source visible in Chandra data near the center of
G21.5-0.9 and have therefore confirmed this pulsar-SNR association beyond
any doubt.  More unexpectedly, we have been able to measure this pulsar's
braking index, n = 2.18, only the 6th such phase-coherent measurement
done in over 1700 pulsars known.  We now have a chance to measure the
"second braking index" and place further constraints on the spin-down law
obeyed by this pulsar.  This has been done to date for only 2 pulsars.
Finally, we wish to continue timing this pulsar because it will be one of
the prime candidates for gamma-ray detection with the GLAST satellite to
be launched in 2007, and in order to do so we must maintain its timing
solution.  For these reasons we request 24 hr for timing PSR J1833-1034
during the present semester.

title: Parkes observations for project P510 semester 2006APRS

description: We request 9 regularly-spaced epochs to carry out high-precision
timing and polarimetry of PSR~J1906+0746, a new relativistic binary
pulsar discovered in the PALFA survey.
It is currently unclear whether the companion star to this young
144-ms pulsar is a white dwarf or another neutron star.  The proposed
observations would measure at least two further post-Keplerian
parameters and determine the mass and inclination of the system.
In addition, they would allow us to measure the significant
profile variations expected due to relativistic spin-orbit coupling.
Given the exciting possibility of a second neutron star in this
system, we shall also use these observations carry out searches for
pulsations from the companion.

title: Parkes observations for project P456 semester 2006OCTS

description: The Parkes Pulsar Timing Array (PPTA) project has three main goals: detection of gravitational waves from astronomical sources, investigation of the stability of terrestrial clocks and improvement of our understanding of Solar-system dynamics. Achievement of these goals requires frequent observations of about 20 MSPs at three widely spaced frequencies over several years. We propose to observe such a sample at 2-weekly intervals using both the 10/50cm and Multibeam or H-OH receivers. The prototype digital filterbank, the wideband correlator and CPSR2 will be used for data recording. With continued development of observing and data analysis systems we are making good progress toward our goals with sub-microsecond precision already achieved on nearly half of the sample. Further improvement is expected with the commissioning of the final digital filterbank system and development of a new-generation baseband system based on it. Because of the high sensitivity and wide bandwidths required, RFI mitigation is an important part of the project.

description: We propose to continue undertake a pulsar survey along the Galactic Plane using the new Methanol Multibeam receiver in order to uncover pulsars previously selected against in lower frequency surveys. The scientific aims of this survey are
(a) to discover young pulsars in the spiral arms, hidden at lower frequencies, (b) to improve our knowledge of the distribution of dispersing and scattering material, particularly in the inner Galaxy, (c) strike it lucky and discover unique objects (e.g. a pulsar with a black hole companion and short period binary pulsars) and
(d) to survey the transient radio sky at high frequencies. Simulations have shown that we expect to find a total of 200 pulsars of which about one half will be new detections.

title: Parkes observations for project P602 semester 2008APRS

description: Only two magnetars are known to emit radio pulsations.  This emission
(discovered at Parkes) is transient and has very unusual and variable
properties compared to ordinary pulsars (flat spectrum, changing
pulse profiles and fluxes).  The torque experienced by these stars (as
inferred from their changing period derivative) also varies enormously.
Here we propose to continue studying these remarkable neutron stars.
For XTE J1810-197 we require only monthly observations, mainly to monitor
its flux density and polarimetry (we obtain the required weekly timing
measurements at the GBT).  For 1E 1547.0-5408, which cannot be observed
with northern telescopes, we require weekly timing measurements, and
monthly flux/polarimetry measurements.  As part of this study, we are
also monitoring both pulsars with the Swift X-ray satellite.

description: Here we propose to continue studying the only two magnetars known to emit
radio pulsations.  The aim is to develop a more specific understanding of
the dynamical behavior of their ultra-strong magnetic fields, which are
responsible for X-ray and gamma-ray outbursts, magnetospheric currents
and particle acceleration, and heating of the neutron star surface.
Most of our time request is for 1E 1547.0-5408, which cannot be observed
with northern telescopes, and has been remarkably active over the past
few months: on October 3, 2008, the pulsar displayed a large X-ray
outburst, accompanied by a very large period glitch; at the same time
radio emission ceased.  The X-ray flux is gradually decaying, and on
December 11 we have redetected radio activity.  Meanwhile, the torque
on the star continues to vary enormously.  At Parkes we will require
nearly weekly timing to reliably track its rotation, while we monitor
its X-ray flux with the Swift satellite.  For both magnetars we also
request bi-monthly polarimetry and flux measurements.

Until now this subject has relied overwhelmingly on X-ray observations.
For these two objects, radio provides an additional window through which
to study the magnetar phenomenon.  The radio emission (discovered at
Parkes) is variable and has properties, different from ordinary pulsars,
that are not yet understood (flat spectrum, changing fluxes and pulse
profiles).  The torque experienced by these two stars varies enormously,
and can only be tracked now in the radio.  Most of our time request is
for 1E 1547.0-5408 which cannot be observed with northern telescopes.

description: The Parkes Pulsar Timing Array (PPTA) project has three primary goals: (a) detection of gravitational waves from astronomical sources, (b) establishment of a pulsar timescale, and (c) improvement of our understanding of Solar-system dynamics. There are many secondary goals, some astrophysical and some instrumental/technique oriented. Achievement of these ambitious primary goals requires frequent observations of at least 20 MSPs at two or preferably three widely spaced frequencies over several years. We wish to continue observing the PPTA sample at intervals of 2-3 weeks using both the 10/50cm and Multibeam receivers. The digital filterbanks (PDFB3, PDFB4) and the baseband system (APSR) are used for data recording. With the new instruments and development of an efficient pipeline processing system, we have achieved the world's best pulsar timing precision, with four pulsars having rms residuals of less than or about 100 ns and 13 less than 1 microsecond. We are collaborating with the European and North American pulsar timing array groups (EPTA and NANOGrav, respectively) to obtain more frequent observations and a larger pulsar sample. Because of the high sensitivity and wide bandwidths required, RFI mitigation is an important part of the project.

possible revival.  1E 1547.0-5408, which cannot be observed with northern

following a large X-ray outburst in October, radio emission ceased,
recommencing sporadically in December.  In January a much larger X-ray
outburst occurred, and while there has been huge variation in flux,
radio emission now remains mostly detectable.  The X-ray flux is

description: We have detected dispersed radio pulsations positionally coincident with
a magnetar candidate.  If they arise from the magnetar, this would be
only the second such instance.  On the other hand, maybe the candidate
is not a magnetar - but the unusual radio pulsations are certainly real.
We therefore wish to get to the bottom of this potentially very exciting
discovery.  The immediate need is to characterize the behavior of the
radio emission, and over a period of approximately one year attempt to
obtain a timing position to compare to the precisely-known position of
the X-ray source.
