nano-sized batio3 powders with particular nb concentrations were prepared by rotary- hydrothermal (rh) method. hydrothermal method was used at 180 °c for 5 hours with new ti pressure and the teflon vessel was rotated at a speed of 160 rpm during the hydrothermal reaction. new hydrothermal method was used instead of previous solid state reaction for the system batio3±nb2o3 in high temperature to...

Planar functions over finite fields give rise to finite projective planes. They were also used in the constructions of DES-like iterated ciphers, error-correcting codes, and codebooks. They were originally defined only in finite fields with odd characteristic, but recently Zhou introduced pesudo-planar functions in even characteristic which yields similar applications. All known pesudo-planar f...

TREC-9 evaluation experiments at the Justsystem site are described with a focus on “aboutness” based approach in text retrieval. Experiments on the effects of supplemental noun phrase indexing, pseudo-relevance feedback and reference database feedback in view of the effect of various length of queries are reported. The results show that pesudo-relevance feedback is always effective while refere...

— this paper outlines a number of steps for human-computer interaction design using sound as representation-auditory icons. The design process is based on listening tests, gathering free-text identification responses from participants. These responses and their classifications can then suggest how accurately the sounds can be identified and possible metaphors and mappings of sound to human acti...

Multidimensional scaling (MDS) is an attractive technique for a moving source localisation from time and frequency difference of arrival (time differences (TDOA)/frequency (FDOA)) measurements. However, its optimality has not yet been proven theoretically because the difficult Moore–Penrose pesudo-inverse operation. In addition to theoretical incompleteness MDS technique, sensor uncertainties a...
