As two important operations in data cleaning, similarity join and similarity search have attracted much attention recently. Existing methods to support similarity join usually adopt a prefix-filtering-based framework. They select a prefix of each object and prune object pairs whose prefixes have no overlap. The authors have an observation that prefix lengths have significant effect ...

Research in social science has shown that mobile phone conversations distract users, presenting a significant impact to pedestrian safety; for example, a mobile phone user deep in conversation while crossing a street is generally more at risk than other pedestrians not engaged in such behavior. The authors propose WalkSafe, an Android Smartphone application that aids ...

The effects of data center traffic characteristics on data center traffic engineering is not well understood. In particular, it is unclear how existing traffic engineering techniques perform under various traffic patterns, namely how do the computed routes differ from the optimal routes. The authors’ study reveals that existing traffic engineering techniques perform 15% to 20% ...

In this paper, the authors propose Airshark – a system that detects multiple non-WiFi RF devices in real-time and using only commodity WiFi hardware. To motivate the need for systems like Airshark, they start with measurement study that characterizes the usage and prevalence of non-WiFi devices across many locations. They, then present the design and ...

Java is slowly being accepted as a language and platform for embedded devices. However, the memory requirements of the java library and runtime are still troublesome. A java system is considered small when it requires less than 1 MB, and within the embedded domain small microcontrollers with a few KB on-chip flash memory and even ...

In spite of the omnipresence of parallel (multi-core) systems, the predominant strategy to evaluate window-based stream joins is still strictly sequential, mostly just straightforward along the definition of the operation semantics. In this paper, the author’s present handshake join, a way of describing and executing window-based stream joins that is highly amenable to parallelized execution. ...

In this paper, the authors study TSV-to-TSV coupling in 3D ICs. A full-chip SI analysis flow is proposed based on the proposed coupling model. Analysis results show that TSVs cause significant coupling noise and timing problems despite that TSV count is much smaller com-pared with the gate count. Two approaches are proposed to alleviate TSV-to-TSV ...

In this paper, the authors propose LEAP: a simple framework for Enterprise Architecture (EA) that views an organization as an engine that executes in terms of hierarchically decomposed communicating components. The approach allows all aspects of the architecture to be precisely defined using standard modeling notations. Given that the approach is simple and precisely defined ...

GPU architectures are increasingly important in the multi-core era due to their high number of parallel processors. Performance optimization for multi-core processors has been a challenge for programmers. Furthermore, optimizing for power consumption is even more difficult. Unfortunately, as a result of the high number of processors, the power consumption of many-core processors such as ...

Graphics Processing Unit (GPU) has been around for a while. Although they are primarily used for high-end 3D graphics processing, their use is now acknowledged for general massive parallel computing. This paper presents an original technique based on to compute many instances of the longest common subsequence problem on a generic GPU architecture using classic ...
