We describe DCU’s participation in the NTCIR-12 SpokenQuery&Doc (SQD-2) task. In the context of the slide-group retrieval sub-task, we experiment with a passage retrieval method that re-scores each passage according to the relevance score of the document from which the passage is taken. This is performed by linearly interpolating their relevance scores which are calculated using the Okapi BM25 ...

In the era of data science, it is common to encounter with different subsets variables obtained for cases. An example split questionnaire design (SQD), which adopted reduce respondent fatigue and improve response rates by assigning sampled respondents. A general question then how estimate regression function based on such block-wise observed data. Currently, this often carried out aid missing m...

The concept of school sport on which we are basing our experience is set in the Historical Territory of Bizkaia (Basque Country, Spain) and this is regulated by Bizkaia’s Diputación Foral (Provincial Council), governed by the regional regulations of the Basque Government. This government takes the view that School Sport covers sport activities at teaching centres outside actual school teaching ...

This paper describes a method for the removal of acid-soluble lignin from acid-hydrolyzed hemicelluloses extracted from a mixture of northern US hardwood chips, by using Amberlite XAD-4 resin, which was shown to remove 100% of furan derivatives and 90% of acid-soluble lignin. Subsequent fermentation of the resin-treated hydrolyzates gave ethanol yields as high as 97% of theoretical and showed a...

Electrodeposition of a roughened copper coating onto steel was carried out to produce bonding surface for thermoplastic resin (polyphenylenesulfide). The film electrodeposited using sulfate bath containing polyacrylic acid (PAA). Following injection molding the resin, strength evaluated in tensile lap shear test, followed by durability testing at high temperature and humidity (85 ± 2 °C 85 2% r...

A cyanate ester/microcapsule system with low cure temperature and self-healing " Abstract: Microcapsules filled with epoxy resin were blended into cyanate ester resin to produce systems with low cure temperature and self-healing capacity. A 4,4′-diaminodiphenylsulfone (DDS) curing agent was adopted for the systems. The mechanical properties, thermal stability and self-healing ability of the sys...

Using modified USPHS criteria, we evaluated annually for ten years 91 cases restored with visible light cured posterior composite resin LFP (Base resin: UDMA; filler: micro crushed type, alumino-silicate, barium glass and silica, 85 wt%, 74 vol%). The 91 cases restored with LFP decreased to 68 in ten years. Of the 23 cases that were lost, one resulted from a pulpal reaction immediately followin...

Low cost composite materials are widely used in civil and structural engineering applications. This project uses Epon and chopped hemp to plasticize a commonly used resin, epoxy resin to lower the cost of the composite and to find out the mechanical and thermal properties of the plasticized epoxy resin to see if it is suitable for the said applications. Epon and chopped hemp were mixed together...
