"Fully engaging, well-written, very imaginative . . . A wonderful
debut." -- Irish Times "When you read a novel cover to cover in one
day, you know it's something exceptional." -- John Boyne, author of
The Boy in the Striped Pajamas Outside an east Belfast mission
hall, pastor and family man Samuel Orr meets Anna, a young Beckett
scholar. They embark on an intense, passionate affair, their
connection both intellectual and erotic. When Anna falls pregnant,
the affair is revealed. The repercussions are slow to emerge but
inescapable, and the fallout, when it finally comes, is shocking.
Over thirty years later Sam, their son, is in New York, living a
steady, guarded life, his childhood and family safely abandoned.
But when the past once more crashes into his life, he is forced to
confront the fears he has kept close all these years. "Brilliantly
written throughout . . . With tight, dispassionate, superbly
controlled prose, Harrison channels the spirit of Don DeLillo or
Camus." -- Irish Independent "Harrison's elegant prose and deeply
felt characters create a novel with a fiercely beating heart." --
Kirkus Reviews "Written with burning intensity . . . Powerful." --

Although applications for Statistical Energy Analysis (SEA)
techniques are more widely used in the aerospace industry today,
opportunities to anchor the response predictions using measured
data from a flight-like launch vehicle structure are still quite
valuable. Response and excitation data from a ground acoustic test
at the Marshall Space Flight Center permitted the authors to
compare and evaluate several modeling techniques available in the
SEA module of the commercial code VA One. This paper provides an
example of vibration response estimates developed using different
modeling approaches to both approximate and bound the response of a
flight-like vehicle panel. Since both vibration response and
acoustic levels near the panel were available from the ground test,
the evaluation provided an opportunity to learn how well the
different modeling options can match band-averaged spectra
developed from the test data. Additional work was performed to
understand the spatial averaging of the measurements across the
panel from measured data. Finally an evaluation/comparison of two
conversion approaches from the statistical average response results
that are output from an SEA analysis to a more useful envelope of
response spectra appropriate to specify design and test vibration
levels for a new vehicle.
