case that brought down South Korean stem cell researcher Hwang Woo Suk early this year”. The Los Angeles Times editorial page bemoaned that, “Science took an unnecessary leap forward Wednesday,” by attempting to find a technological fix to address political and religious objections to stem-cell research. “It’s an impressive advance, but scientists — and society — would be better off if they cou...

This paper shows the results of a field appliance study hydraulic well method to prevent embankment piping, which is proposed by Japanese Matsuyama River National Highway Office. The large-scale experiment and seepage analysis were conducted examine well. experimental procedure focused on pore water pressure. levels compared with pressure data, used look over variations. Two different types exp...

The paper deals with an analysis of time series of heat demand course. The course of heat demand and heat consumption can be demonstrated by means of heat demand diagrams. The most important one is the Daily Diagram of Heat Supply (DDHS) which demonstrates the course of requisite heat output during the day. This analysis is utilized for building up a prediction model of the DDHS. Forecast of th...

This paper presents ‘‘contribution to sample variance plot’’, a natural extension of the ‘‘contribution to the sample mean plot’’, which is a graphical tool for global sensitivity analysis originally proposed by Sinclair. These graphical tools have a great potential to display graphically sensitivity information given a generic input sample and its related model realizations. The contribution t...

AIMS This study used culture-dependent and culture-independent approaches to characterize bacterial communities in copper plumbing corrosion and to assess biofilm formation and copper resistance of heterotrophic bacteria isolated from copper pipes. METHODS AND RESULTS Water and copper pipes were collected from a cold-water household distribution system affected by 'blue water' corrosion and p...

In this paper, we present two feature extraction techniques for the classification of ultrasonic NDE signals acquired from weld inspection regions of boiling water reactor piping of nuclear power plants. The classification system consists of a pre-processing block that extracts features from the incoming patterns, and of an artificial neural network that assigns the computed features to a parti...
