Appearance of Persistent Scatterers for Different TerraSAR-X Acquisition Modes
TerraSAR-X Persistent Scatterer appearance acquisition modes
2016/1/25
Since beginning of 2008 products of TerraSAR-X have been available for the scientific community and the great performance of this
satellite system has been proven by encouraging results presented du...
evaluation of the potential of sar ers and asar envisat sensors in multi-incidence and multi-polarisation modes for landscape study in french guyana: examples of kourou and saint laurent du maroni
Calibration Comparison Polarization Landscape Radar SAR
2015/9/1
This study aims to assess the contribution of ENVISAT ASAR data for the monitoring of the littoral plains of Kourou and Saint Laurent du Maroni (French Guyana).
It is shown that a transformation of time can allow the periodic solution of a strongly nonlinear oscillator to be written as a simple cosine function. This enables the stability of strongly nonlinear...
Coupled Parametrically Driven Modes in Synchrotron Dynamics
Parametric Coupled Oscillators Mathieu Synchrotron
2015/8/26
This work concerns the dynamics of a type of particle accelerator called a synchrotron, in which particles are made to move in nearly circular orbits of large radius. The stability of the transverse m...
We study the security and privacy of private browsing modes recently added to all major browsers. We first propose a clean definition of the goals of private browsing and survey its implementation in ...

Preservation of and reinvestment in the built environment as a redevelopment tool has been used by cities and towns across the country, in many cases providing significant social, economic and environ...
Broadband light management using low-Q whispering gallery modes in spherical nanoshells
Broadband light management whispering gallery modes spherical nanoshells
2015/8/7
Light trapping across a wide band of frequencies is important for applications such as solar cells and photodetectors. Here, we demonstrate a new approach to light management by forming whispering-gal...
Temporal coupled mode theory for thermal emission from a single thermal emitter supporting either a single mode or an orthogonal set of modes
Temporal coupled thermal emission single thermal emitter supporting either
2015/8/7
We propose a temporal coupled mode theory for thermal emission from a single emitter supporting either a single mode or an orthogonal set of modes. This temporal coupled mode theory provides analytic ...

2013/2/27
Monthly mean summer (DJF) temperature and precipitation from Global Historical Climate Network (GHCN-V3) for the period of 1870-2011, are analyzed to assess the role of teleconnections on climate of D...
Tunable Reflection Bands and Defect Modes in One-Dimensional Tilted Photonic Crystal Structure
Photonic Crystal Structure Photonic Band Gap (PBG) Omnidirectional Reflector Tilted PC Structure De-fect Modes
2013/1/30
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...

Long-lived and unstable modes Brownian suspensions microchannels Fluid Dynamics
2012/4/24
We investigate the stability of the pressure-driven, low-Reynolds flow of Brownian suspensions with spherical particles in microchannels. We find two general families of stable/unstable modes: (i) deg...
Wave transport in disordered systems is a vast research topic, ranging from electrons in semiconductors, to light in random dielectrics, to cold atoms in laser speckles. In optics, light transport is ...
属性赋权的K-Modes算法优化
K-Modes聚类 属性选择 自动属性赋权
2012/3/13
传统K-Modes算法的一个主要问题是属性选择问题。K-Modes算法在聚类过程中对每一个属性都同等看待, 而在实际应用中, 很多数据集仅有几个重要属性对聚类起作用。为了考虑不同属性对聚类的不同影响, 将K-Modes聚类算法与属性权重的最优化结合起来, 提出一种属性自动赋权的FW-K-Modes算法。该算法不仅可以提高传统K-Modes聚类算法的聚类精度, 还能分析各维属性对聚类的贡献程度, 实...
