Worldless
Worldless (dis)places its visitors within an uncanny space of four speakers, three screens and two time periods in approaching the one death that we all see uncannily in front of us. This spooky installation, based around the abandoned Japanese theme park Nara Dreamland, imagines a time when everything has fallen in war and has worn away into the universal ash
The Russell Chantry: Lothar Götz/ Duncan Grant
Geom is a new sound wall commission by David McSherry for the exhibition, The Russell Chantry: Lothar Götz/ Duncan Grant. In this piece, David uses sound to respond to the work of both Duncan Grant and Lothar Götz, creating an entirely new experience.
Sacred music is at the centre of this composition. David chose John Taverner's 'The Lamb' as a starting point, in response to the imagery of the Good Shepherd in Duncanâs mural. Religious music also plays an important role in our experience of the original Russell Chantry mural, the sound of choirs and hymns permeate into the chapel space from the main cathedral. This work brings our attention to something we do not often consider when in an art gallery, the sounds around us and how these can affect our experience.
After deconstructing the harmonic aspects of 'The Lamb', David then uses simple triangle waveforms and a 'geometric sequencer' in order to create rhythmic patterns in the piece, in response to Lotharâs geometric shapes. Playing the work across the 22 audio channels of our permanent soundwall creates what David calls audible âsound shapesâ. Here David pushes the boundaries between visual and audible art and experience
Sedimentation study, Environmental Monitoring and Operations Guidance System (EMOGS), Kings Bay, Georgia and Florida, 1988-1990 : final report
Repeated side-scan sonar and multi-frequency bathymetric surveys, accompanied by accurate, high resolution, and repeatable
navigation, were conducted in the vicinity of a tidal inlet to define the length and time scales associated with bedforms and channel
shoaling in a structured tidal inlet. The study site, St. Marys entrance channel along the Georgia/Florida border (Fig. 1), has a
dredged channel approximately 46-52 feet in depth at a datum of mean low water (MLW), bordered by a large ebb tidal delta. The
tidal inlet serves Cumberland Sound, Kings Bay, and associated waterways, providing a large discharge of water from the inlet that
creates bedforms and channel shoaling, given the abundance of sand-size sediment in the vicinity. The jettied inlet produces flows
that are predominantly tidally-driven, whereas farther offshore the driving forces consist predominantly of waves and
storm-generated flows. In the channel reaches (Table 1) between these two areas, combined wave/steady flows are present, creating
a myriad of scales of bedforms and shoaling patterns, emphasizing the difference in these scales between the three different flow
regimes. The results provide an important data base for quantifying shoaling processes and mechanisms in tidal inlet channels.Funding was provided by the National Oceanic & Atmospheric Administration's Sea Grant Program through Grant NA860-A-D-090
Sedimentation study, Environmental Monitoring and Operations Guidance System (EMOGS), Kings Bay, Georgia and Florida : Phase III--FY 1989
Repeated side-scan sonar and multi-frequency bathymetric surveys, accompanied by accurate, high resolution, and repeatable
navigation, were conducted in the vicinity of a tidal inlet to define the length and time scales associated with bedforms and channel
shoaling in a structured tidal inlet. The study site, St. Mary's entrance channel along the Georgia/Florida border (Fig. I), has a
dredged channel approximately 46-52 feet in depth, bordered by a large ebb tidal delta. The tidal inlet serves Cumberland Sound,
Kings Bay, and associated waterways, providing a large discharge of water from the inlet that creates bedforms and channel
shoaling, given the abundance of sand-sized sediment in the vicinity. The jettied inlet produces flows tht are predominately
tidally-driven, whereas farther offshore the driving forces consist predominately of waves and storm-generated flows. In the
channel reaches (Table 1) between these two areas, combined wave-steady flows are present, creating a myriad of scales of
bedforms and shoaling patterns. This study was designed to elucidate the time and space scales of these variable bedforms and
shoaling patterns, emphasizing the difference in these scales between the three different flow regimes. The results provide an
important data base for quantifying shoaling processes and mechanisms in tidal inlet channels.Funding was provided by the National Oceanic Atmospheric Administration

Hydroblack 91 : report of the CTD Intercalibration Workshop
An Intercalibration Workshop was held at the Woods Hole Oceanographic Institution
(W.H.O.I.) from 1-10 December, 1991, for the CTD data acquired during HYDROBLACK '91.
This intercalibration exercise was a prelude to an interdisciplinary HYDROBLACK '91
intercalibration to be held in Crimea, Ukraine, in February, 1992, incorporating the full suite of physical, biological, and chemical measurements acquired during the cruise.
HYDROBLACK '91 acquired for the first time a complete hydrographic, biological, and
chemical data set for the entire Black Sea, to 200 m water depth, with the participation of all Black
Sea riparian countres as well as the U.S. Nearly 300 hydrographic stations were occupied to full
water depth; biological and chemical measurements were made at 100 of these stations. This
quasi-synoptic survey was accomplished using five ships during an interval of approximately three
weeks.
Results show some disparities between CTD's from the different regions, but the
intercalibrated results show a consistent and high resolution detail of the dynamic topography and
other physical characteristics of the entire Black Sea basin. The intercalibrated data set is now
available within each country and from W.H.O.I., and will form the basis for studies on ocean
physics as well as interdisciplinary issues such as oxygen depletion within the basin and hydrogen
sulfide distribution. This effort provides an intercalibrated, spatially-dense baseline against which
all future and past measurements can be compared.
In spite of significant economic pressures arising from the changes in the eastern European
countries, and the inadequate scientific exchange with the west during the past two decades,
HYDROBLACK '91 is considered a success and a model for future international scientific and
monitoring efforts thoughout the Black Sea. Similar efforts are anticipated twice-yearly in the
framework of the new Cooperative Marine Science Program for the Black Sea.Funding was provided by the National Science Foundation through Grant No. OCE-9121788, the

Fast matrix computations for pair-wise and column-wise commute times and Katz scores
We first explore methods for approximating the commute time and Katz score
between a pair of nodes. These methods are based on the approach of matrices,
moments, and quadrature developed in the numerical linear algebra community.
They rely on the Lanczos process and provide upper and lower bounds on an
estimate of the pair-wise scores. We also explore methods to approximate the
commute times and Katz scores from a node to all other nodes in the graph.
Here, our approach for the commute times is based on a variation of the
conjugate gradient algorithm, and it provides an estimate of all the diagonals
of the inverse of a matrix. Our technique for the Katz scores is based on
exploiting an empirical localization property of the Katz matrix. We adopt
algorithms used for personalized PageRank computing to these Katz scores and
theoretically show that this approach is convergent. We evaluate these methods
on 17 real world graphs ranging in size from 1000 to 1,000,000 nodes. Our
results show that our pair-wise commute time method and column-wise Katz
algorithm both have attractive theoretical properties and empirical
performance.Comment: 35 pages, journal version of

Retrieval, reuse, revision and retention in case-based reasoning
El original estĂĄ disponible en www.journals.cambridge.orgCase-based reasoning (CBR) is an approach to problem solving that emphasizes the role of prior experience during future problem solving (i.e., new problems are solved by reusing and if
necessary adapting the solutions to similar problems that were solved in the past). It has enjoyed considerable success in a wide variety of problem solving tasks and domains. Following a brief
overview of the traditional problem-solving cycle in CBR, we examine the cognitive science foundations of CBR and its relationship to analogical reasoning. We then review a representative selection of CBR research in the past few decades on aspects of retrieval, reuse, revision, and retention.Peer reviewe
