A class of pseudo-random compound error-correcting codes, called Generalized Low-Density (GLD) Parity-Check codes, has been proposed recently. As a generalization of Gallager’s Low-Density ParityCheck (LDPC) codes, GLD codes are also asymptotically good in the sense of minimum distance criterion and can be effectively decoded based on iterative soft-input soft-output (SISO) decoding of individu...

Cultural heritage, and other special domains, pose a particular problem for information retrieval: evaluation requires a dedicated test collection that takes the particular documents and information requests into account, but building such a test collection requires substantial human effort. This paper investigates methods of generating a document retrieval test collection from a search engine’...

This note presents a non trivial combination of two techniques previously used with randomized incremental algorithms: the lazy cleaning scheme [dBDS94] to maintain structures with `non local' de nition and the O(n log n) acceleration when some additional information about the data is known [Sei91, CCT92, Dev92]. Authors assume that the reader is somehow familiar with this techniques. If, we ar...

I'm working in a large health care institution that operates a hospital, a day surgery center, nursing homes, urgent care and occupational medicine facilities, and medical office buildings on four campuses, two community health clinics, as well as eight home health agencies in surrounding counties. We have installed a firewall to segregate the main campus network, a Frame Relay network connecti...

A distributed neural network, running on a large transputer-based parallel computer, was trained to identify the presence of the main lithographical facies types in a particular oil well, using only the readings obtained by a log probe. The resulting trained network was then used to analyse a variety of other wells, and showed only a small decrease in accuracy of identiication. Geologists class...

In this paper, we propose a new definition of intuitionistic fuzzyquasi-metric and pseudo-metric spaces based on intuitionistic fuzzy points. Weprove some properties of intuitionistic fuzzy quasi- metric and pseudo-metricspaces, and show that every intuitionistic fuzzy pseudo-metric space is intuitionisticfuzzy regular and intuitionistic fuzzy completely normal and henceintuitionistic fuzzy nor...

Solder joints formed in microgravity are inferior to Earth gravity. They mechanically weaker and less electrically conductive due voids forming the when soldering microgravity. Surface tension lack of gravitational buoyancy combine prevent flux water vapors from escaping molten solder absence gravity, resulting more porous joints. Additionally, corrosive vapor products remain trapped causing fu...

Additive manufacturing techniques can produce complex, high-value metal parts, with potential applications as critical metal components such as those found in aerospace engines and as customized biomedical implants. Material porosity in these parts is undesirable for aerospace parts - since porosity could lead to premature failure - and desirable for some biomedical implants - since surface-bre...
