We consider the design of kernels for time-frequency distributions through the phase, rather than amplitude, response. While phase kernels do not attenuate troublesome crosscomponents, they can translate them in the time-frequency plane. In contrast to previous work on phase kernels that concentrated on placing the cross-components on top of the auto-components, we set up a “don’t care” region ...

A commonsensical way of relating photography to memory is one that assumes that photographs in some way “preserve” or “capture” memories for posterity. A photograph album with the inscription “Treasured Memories” on the cover, or a Kodak ad promoting the camera “as a means of keeping green the Christmas memories” (Paster 1992: 138), are perhaps the most quotidian instantiations of this assumpti...

We participated in the MediaEval Benchmarking whose goal is to concentrate on the multimodal geo-location prediction on the Yahoo! Flickr Creative Commons 100M dataset the placing task. It challenges participants to develop models and/or techniques to estimate the geographic locations of the Flickr resources based on textual metadata, e.g. titles, descriptions and tags. We aim to find a procedu...

Abstract-A novel and efficient method has been developed for the synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives by the convenient ultrasound-mediated condensation of 4-hydroxyquinolin-2-one with Meldrum’s acid and aldehydes in the presence of a catalytic amount of [HMIm]HSO4 as a green, efficient and reusable acidic ionic liquid medium. The stability of the ionic liquid during the re...
