This paper provides a brief description of the system for recognizing textual entailment (RTE) Language Computer Corporation (LCC) used in the 2008 TAC RTE-4 Evaluation. Our RTE-4 work follows our previous work (Hickl and Bensley, 2007; Bensley and Hickl, 2008; Hickl, 2008) in using a pipeline of lightweight, largely statistical systems for commitment extraction, lexical alignment, and entailme...

A high speed 15 ns 4 Mbits asynchronous SRAM, 500 Astand-by current, 300 Krads total dose tolerant, has been developed for space applications, using a hardened 0.25 micron 4 layers metal full CMOS process. A hierarchical organisation per IO bits has been used to achieve high speed as well as low dynamic consumption, also suited for simple SEU (single event upset) induced error corrections, allo...

The bridge-substituted calix[4]arene carboxylic acid, 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetramethoxy-calix[4]arene-2-carboxylic acid (1), can be readily converted to various esters 2-4 and reduced to the alcohol 5, which reacts with methyl iodide to give the ether 6. The alcohol can be dansylated to give 7, the fluorescence of which is selectively quenched by Cu(II) in acetonitrile. An at...

Committee 4 develops principles and recommendations on radiological protection of people in all exposure situations. The committee meeting in 2014 was hosted by GE Healthcare in Arlington Heights, IL, USA on 27 July-1 August 2014. The programme of work of Committee 4 encompasses several broad areas, including a series of reports covering various aspects of existing exposure situations, leading ...

Clustering is vital in the process of condensing and outlining information, since it can provide a synopsis of the stored data. However, the high dimensionality of multimedia data today presents an insurmountable challenge for clustering algorithms. Based on the well-known fact that time series and image histograms can both be represented accurately in a lower resolution using orthonormal decom...

MPEG-4 is an object-oriented video compression standard which allows content-based representation of a video sequence. This requires a decomposition of scenes into semantic video objects (VOs). Many algorithms had been developed to extract VOs with accurate boundaries, however, the issue of multiple objects is less addressed. We proposed to use a simple clustering method based on distance trans...

In this work, we report a method to process porous silicon to improve its chemical resistance to alkaline solution attacks based on the functionalization of the pore surface by the electrochemical reduction of 4-nitrobenzendiazonium salt. This method provides porous silicon with strong resistance to the etching solutions used in optical lithography and allows the fabrication of tailored metalli...
