This book is a review and analysis of the literature and presenta-
tion of data from a series of surveys that attempts to provide in-
sights into how engineers communicate. Much of the focus of the
book is on the professional aspects of engineers’ work, the infor-
mation resources used to perform their work, and information
output from their work that is communicated to others. Many of
our studies and those of others dealt with traditional interperson-
al and written communication channels....
The asynchrony, heterogeneity, and inherent loose coupling that characterize
applications in a wide-area network promote event interaction as a natural
design abstraction for a growing class of software systems. An emerging build-
ing block for such systems is an infrastructure called an event notiﬁcation ser-
vice [Rosenblum and Wolf 1997].
We envision a ubiquitous event notiﬁcation service accessible fromevery site
on a wide-area network and suitable for supporting highly distributed appli-
cations requiring component interactions ranging in granularity from ﬁne to
While history and examination will always remain the foundation of neurolog-
ical diagnosis, MRI and CT have now become the most important diagnostic
tests used by neurologists and neurosurgeons. These tests are critical not only
for confirming clinical diagnosis, but in many cases will give additional infor-
mation absolutely essential to patient care. Modern clinical diagnosis and treat-
ment of central nervous system disorders relies heavily upon neuroimaging. In
some cases, the optimal management of clinical problems affecting patients
with brain tumors, strokes, etc.
