TL;DR: Guangdong International Building has a height of approximately 200 m with 63 stories and the amplitude-dependent characteristics of damping obtained by the random decrement technique are presented and discussed in this paper, where a series of wind tunnel tests are conducted to determine the spectral model of across-wind force on rectangular tall buildings with various side and aspect ratios.
90 citations
TL;DR: In this article, the authors present the field measurement results of wind characteristics and structural responses of two super tall buildings, Central Plaza Tower (374m, 78 floors) in Hong Kong and Di Wang Tower (384 m, 78 feet) in Shenzhen during the passage of Typhoon Sally.
89 citations
TL;DR: In this article, the results from a combined wind tunnel and full-scale study of wind effects on the super tall building were presented and discussed, and a detailed comparative study was conducted to investigate the influences of incident wind direction, upstream terrain conditions, and interferences from the surroundings on the wind effect on the building.
87 citations
TL;DR: Wang et al. as mentioned in this paper performed a 1:150 scaled wind tunnel testing to experimentally assess the wind speed amplification effects inside the four openings of the Pearl River Tower, a 71-storey tall building in Guangzhou, China.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This thesis applies neural network feature selection techniques to multivariate time series data to improve prediction of a target time series and results indicate that the Stochastics and RSI indicators result in better prediction results than the moving averages.
Abstract: : This thesis applies neural network feature selection techniques to multivariate time series data to improve prediction of a target time series. Two approaches to feature selection are used. First, a subset enumeration method is used to determine which financial indicators are most useful for aiding in prediction of the S&P 500 futures daily price. The candidate indicators evaluated include RSI, Stochastics and several moving averages. Results indicate that the Stochastics and RSI indicators result in better prediction results than the moving averages. The second approach to feature selection is calculation of individual saliency metrics. A new decision boundary-based individual saliency metric, and a classifier independent saliency metric are developed and tested. Ruck's saliency metric, the decision boundary based saliency metric, and the classifier independent saliency metric are compared for a data set consisting of the RSI and Stochastics indicators as well as delayed closing price values. The decision based metric and the Ruck metric results are similar, but the classifier independent metric agrees with neither of the other metrics. The nine most salient features, determined by the decision boundary based metric, are used to train a neural network and the results are presented and compared to other published results. (AN)
