Mapping an algorithm to an architecture with faults is an important problem in parallel processing. This paper deals with wrapped butterfly architectures with edge faults. We investigate the effect of automorphisms of a wrapped butterfly on its edges. Given a fault set, one can then choose an appropriate automorphism to map the algorithm to use only fault-free edges. By using an algebraic model...

Mani Earthquake, occurred on Nov. 8, 1997 in Tibet, China, is the strongest event in China since 90’s in 20 century. Investigation and research of its principle and geometry, dynamics related to surface rupture zone is very significant to analyze the development and evolution of China’s earthquake in the future. In this study, we investigate the distribution of surface deformation and extract d...

We investigate the problem of constructing spanners for a given set of points that are tolerant for edge/vertex faults. Let S IRd be a set of n points and let k be an integer number. A k-edge/vertex fault tolerant spanner for S has the property that after the deletion of k arbitrary edges/vertices each pair of points in the remaining graph is still connected by a short path. Recently it was sho...

as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

In contrast to a widely held belief among politicians and science managers, the course of science is unpredictable and difficult to steer. The reason is that management is based on the knowledge of today, whereas science is about the knowledge of tomorrow. As Sir Karl Popper (1957) remarked: ‘‘We cannot anticipate today what we shall know only tomorrow.’’ Anyone who specifies the key issues in ...

As current editor-in-chief and executive editor for the Journal of Cell Biology, we are writing to describe our shared vision for the journal: To enable the swift and painless publication of advances and thought-provoking ideas in a range of fields that inform cell biology, and to promote this high-quality work as broadly as possible in our community. Throughout 2015, we celebrated the 60th ann...

Empirical studies conducted by the researchers on object-oriented design metrics are useful for forecasting the fault-proneness of classes in object-oriented design. In this study, we propose an integrated hybrid model to empirically investigate the fault-proneness of object-oriented design. We will use a subset of the Chidamber and Kemerer suite and all of the MOOD metrics to predict fault-pro...
