Broadcast News Story Segmentation Using Social Network Analysis and Hidden Markov Models

Sarah Favre, Alessandro Vinciarelli

This paper presents an approach for the segmentation of broadcast news into stories. The main novelty of this work is that the segmentation process does not take into account the content of the news, i.e. what is said, but rather the structure of the socia ...

Relation of expansion due to alkali silica reaction to the degree of reaction measured by SEM image analysis

Karen Scrivener, Emmanuel Gallucci, Mohsen Ben Haha, Amor Guidoum

Scanning Electron Microscopy Image Analysis (SEM-IA) was used to quantify the degree of alkali silica reaction in affected microbars, mortar and concrete prisms. It was found that the degree of reaction gave a unique correlation with the macroscopic expans ...

Electrochemical modification of the catalytic activity of TiO2/YSZ supported rhodium films

Christos Comninellis, György Foti

The electrochemical activation of ethylene oxidation was studied over rhodium catalysts of different thickness (40, 100 and 160 nm) sputtered on top of a thin layer of TiO2 deposited on YSZ. The strong relationship between catalytic activity and oxidation ...

Quantitative microstructural characterisation of concrete cured under realistic temperature conditions

Xinyu Zhang

The curing temperature is known to influence the strength and durability of concrete. In general, curing at elevated temperature results in high early strength gain, but impairs the long-term strength and transport properties. Previous investigations have ...
