SPATIO-TEMPORAL CHANGE OF VEGETATION COVERAGE AND ITS DRIVING FORCES BASED ON LANDSAT IMAGES: A CASE STUDY OF CHANGCHUN CITY
Vegetation Coverage NDVI Spatio-Temporal Variations Remote Sensing Changchun
2018/5/11
Based on the Landsat images in 2006, 2011 and 2015, and the method of dimidiate pixel model, the Normalized Difference Vegetation Index (NDVI) and the vegetation coverage, this paper analyzes the spat...

ANALYSIS OF URBAN DEVELOPMENT BY MEANS OF MULTI-TEMPORAL FRAGMENTATION METRICS FROM LULC DATA
Fragmentation Metrics Urban Change Growth Patterns
2015/5/7
The monitoring and modelling of the evolution of urban areas is increasingly attracting the attention of land managers and administration. New data, tools and methods are being developed and made av...
The Ethical Mirage:A Temporal Explanation as to Why We Aren't as Ethical as We Think We Are
Forecasting and Prediction Ethics Behavior Cognition and Thinking Perception Prejudice and Bias
2015/4/21
This paper explores the biased perceptions that people hold of their own ethicality. We argue that the temporal trichotomy of prediction, action and evaluation is central to these misperceptions: Peop...
Volatilities That Change with Time: The Temporal Behavior of the Distribution of Stock-Market Prices
spectral analysis noise reduction Rademacher distribution
2010/10/21
While the use of volatilities is pervasive throughout finance, our ability to determine the instantaneous volatility of stocks is nascent. Here, we present a method for measuring the temporal behavior...
Investigating Causal Relationships in Stock Returns with Temporal Logic Based Methods
Investigating Stock Returns Temporal Logic Based Methods
2010/10/20
We describe a new framework for causal inference and its application to return time series. In this system, causal relationships are represented as logical formulas, allowing us to test arbitrarily co...
Temporal structure and gain/loss asymmetry for real and artificial stock indices
Temporal structure gain/loss asymmetry mutual information
2010/11/1
We demonstrate that the gain/loss asymmetry observed for stock indices vanishes if the temporal dependence structure is destroyed by scrambling the time series. We also show that an artificial index c...
Structure and temporal change of the credit network between banks and large firms in Japan
Banking Credit topology Bipartite network Systemic risk
2010/10/29
We present a new approach to understanding credit relationships between commercial banks and quoted firms, and with this approach examine the temporal change in the structure of the Japanese credit ne...
We investigate financial market correlations using random matrix theory and principal component analysis. We use random matrix theory to demonstrate that correlation matrices of asset price changes co...
