Model Reduction for Analysis of Cascading Failures in Power Systems
Power Systems Cascading Failures
2015/6/19
In this paper, we apply a principal-orthogonal decomposition based method to the model reduction of a hybrid, nonlinear model of a power network. The results demonstrate that the sequence of fault eve...
Ocean acidification a culprit in commercial shellfish hatcheries' failures
Ocean acidification culprit in commercial shellfish hatcheries' failures
2014/12/30
The mortality of larval Pacific oysters in Northwest hatcheries has been linked to ocean acidification. Yet the rate of increase in carbon dioxide in the atmosphere and the decrease of pH in near-shor...
Detection Performance in Balanced Binary Relay Trees with Node and Link Failures
Detection Performance Balanced Binary Relay Trees Node and Link Failures Information Theory
2012/6/14
We study the distributed detection problem in the context of a balanced binary relay tree, where the leaves of the tree are sensors generating binary messages. The root of the tree is a fusion center ...
Optimal adaptive control of cascading power grid failures
Optimal adaptive control power grid failures
2011/2/22
Power grids have long been a source of interesting optimization problems. Perhaps best known
among the optimization community are the unit commitment problems and related generator dispatching tasks,...
Overlay Protection Against Link Failures Using Network Coding
Overlay Protection Link Failures Network Coding
2010/11/22
This paper introduces a network coding-based protection scheme against single and multiple link failures. The proposed strategy ensures that in a connection, each node receives two copies of the same ...
Lessons from failures to achieve what was possible in the twentieth century physics
twentieth century physics quantum physics
2010/3/19
For several decades there has been no breakthrough in fundamental physics as revolutionary as relativity and quantum physics despite the amazing advancement of applied physics and technology. By discu...
Analysis of warm standby systems subject to common-cause failures with time varying failure and repair rates
k-out-of-( M+S) G system, time varying failure and repair rates
2010/9/13
This paper presents reliability and availability analysis of a k-out-of-(M+S): G warm standby system with time varying failure and repair rates in presence of commoncause failure. The system composed ...
Flow-type failures in fine-grained soils:an important aspect in landslide hazard analysis
Flow-type failures fine-grained soils important aspect landslide hazard analysis
2009/12/8
Forecasting the possibility of flow-type failures within a slow-moving landslide mass is rarely taken into account in quantitative hazard assessments. Therefore, this paper focuses on the potential tr...
Rock-slope failures in Norway;type,geometry,deformation mechanisms and stability
Rock-slope failures type geometry deformation mechanisms stability
2009/12/3
Extensive studies of Norwegian rock-slope failure areas support a subdivision into three principle types: (1) Rockfall areas, (2) rockslide areas, and (3) complex fields. The classification is based o...
Why we learn more from our successes than our failures--MIT study sheds light on the brain's ability to change in response to learning
sheds light brain's ability learning
2009/8/3
In the July 30 issue of the journal Neuron, Earl K. Miller, the Picower Professor of Neuroscience, and MIT colleagues Mark Histed and Anitha Pasupathy have created for the first time a unique snapshot...
Slope failures and debris flows due to heavy rainfall are frequent in Japan, which have damaged many lives and properties. They have occurred in this country under geological conditions prone to slop...
Analysis of shallow failures triggered by the 14-16 November 2002 event in the Albaredo valley, Valtellina (Northern Italy)
shallow failures the 14-16 November 2002 event the Albaredo valley
2010/1/22
On 14-16 November 2002 the North Italy was affected by an intense rainfall event: in the Albaredo valley (Valtellina) more than 200 mm of rain fell triggering about 50 shallow landslides, mainly soil ...
The evolution of slope failures:mechanisms of rupture propagation
evolution slope failures mechanisms rupture propagation
2009/12/17
Forecasting the occurrence of large, catastrophic slope failures remains very problematic. It is clear that in order advance this field a greater understanding is needed of the processes through which...
