Due to the diversity and implicit redundancy in terms of processing units and compute kernels, off-the-shelf heterogeneous systems offer the opportunity to detect and tolerate faults during task execution in hardware as well as in software. To automatically leverage this diversity, we introduce an extension of an online-learning runtime system that combines the benefits of the existing performa...

This paper presents a new coarse-grain reconfigurable array optimized for multimedia processing. The system has been designed to provide a dense support for arithmetic operations, wide internal data bandwidth and efficiently distributed memory resources. All these characteristics are combined into a cohesive structure that efficiently supports a block-level pipelined dataflow, which is particul...

2007 January " Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming. Abstract As more devices and systems get woven into the fabric of our networked world, the scale and the complexity of integration is growing at a rapid pace. Our existing methodologie...

Nowadays, application programs are available for a wide variety of domains. The applications are developed using different style-guides for their user interfaces. The way similar tasks are carried out differs depending on the application used. Such inconsistency results in unnecessary learning time and is the cause of mistakes leading to the loss of data and effort. A straight forward approach ...

Data warehousing has largely developed with little or no reference to ObjectOriented Software Engineering (OOSE) [1]. This is consistent with (a) its development out of two-tier client/server relational database methodology, and (b) its character as a kind of high-level systems integration, rather than software development, activity. Data Warehousing assembles components, rather than creating t...

Data series similarity search is a core operation for several data analysis applications across many different domains. However, the state-of-the-art techniques fail to deliver time performance required interactive exploration, or of large collections. In this work, we propose MESSI, first index designed in-memory on modern hardware. Our takes advantage hardware parallelization opportunities (i...

The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality. The presence of asymmetric-tail dependence is not compatible with the assumption of a joint student -t distribution. A general test for ...

A service is a software building block capable of fulfilling a given task or a distinct business function through a well-defined interface, loosely-coupled interface. Services are like "black boxes", since they operate independently within the system, external components are not aware of how they perform their function, they only care that they return the expected result. The Service Oriented A...
