When MIT’s mini cheetah perfectly executed a backflip on “The Tonight Show Starring Jimmy Fallon,” the audience screamed and applauded wildly. If this machine — which also pranced around the stage lik...
The UK's Chancellor Jeremy Hunt has announced that nuclear will "subject to consultation, be classed as environmentally sustainable in our green taxonomy" - he also launched a competition, to be compl...

Even for a second-year PhD student researching the mechanics of living cells, the influence of physical forces within the world of living things is a source of wonder.
Fabricating the large numbers of computer chips that are found in a multitude of everyday objects, from cell phones to car navigation systems, relies on the use of precise, microscopic stencils that c...
NSF-funded leadership-class computing center boosts U.S. science with largest academic supercomputer in the world（图）

Today, the Texas Advanced Computing Center (TACC) at The University of Texas at Austin (UT Austin) launched Frontera, the fastest supercomputer at any university and the fifth most powerful system in ...
First-class Runtime Generation of High-performance Types using Exotypes
First-class Runtime Generation High-performance Types Exotypes
2016/5/24
We introduce exotypes, user-defined types that combine the flexibility of meta-object protocols in dynamically-typed languages with the performance control of low-level languages. Like objects in dyna...
Exploring Semantic Inter-class Relationships (SIR) for Zero-shot Action Recognition
Exploring Semantic Inter-class Relationships Zero-shot Action Recognition
2016/1/22
Automatically recognizing a large number of action cat-egories from videos is of significant importance for video understanding. Most existing works focused on the design of more discriminative featur...
Optimizing Age-of-Information in a Multi-class Queueing System
Optimizing Age-of-Information Multi-class Queueing System
2016/1/22
We consider the age-of-information in a multi-class M/G/1 queueing system, where each class generates packets containing status information. Age of information is a relatively new metric that measures...
CLASS BASED RATIOING EFFECT ON SUB-PIXEL SINGLE LAND COVER AUTOMATIC MAPPING
Sub-pixel Possibilistic c-Means (PCM) Image Ratioing Fuzzy Error Matrix (FERM)
2015/12/31
Sub-pixel based digital image classification outputs from coarse spatial resolution remote sensing images can be closer to ground information as compared to hard classification outputs. This has been ...
Integrating Object-Based Classification and One-Class Support Vector Machines in Classifying a Specific Land Class from High Spatial Resolution Images
Object-Based Classification One-Class Support Vector Machines High Spatial Resolution Imagery
2015/12/17
Remote sensing techniques have been commonly used to map land cover and land use types. For many applications, users may only be interested in a specific land class in an image such as extracting urba...
CLASS MODELLING OF BIOTOPE COMPLEXES – SUCCESS AND REMAINING CHALLENGES
Object-based image analysis aggregated functional units
2015/11/16
Complex real world phenomena require means for reducing and modelling the underlying complexity. They ask for methods and
tools to exploit the crucial information intelligently, for addressing dynam...
On a Class of a Thermal Blow-up Patterns
Thermal explosion the axisymmetric mode the dissipation
2015/10/8
We study the patterns of thermal explosion as described via u_t = (\Delta + 1)u^m, m>1. These processes, characterized by an intrinsic length-scale, always converge into a very simple, universal, spac...
