One Video Stream to Serve Diverse Receivers
(2008-10-18)
The fundamental problem of wireless video multicast is to scalably serve multiple receivers which may have very different channel characteristics. Ideally, one would like to broadcast a single stream that allows each ...
Modular Generation and Customization
(2008-10-10)
Modularity and flexibility can conflict in multi-language systems. For example, the templates commonly used to generate web pages must be manually updated when the database schema changes. Modularity can be improved by ...
ZigZag Decoding: Combating Hidden Terminals In Wireless Networks
(2008-10-01)
This paper presents ZigZag, an 802.11 receiver design that combats hidden terminals. ZigZag's core contribution is a new form of interference cancellation that exploits asynchrony across successive collisions. Specifically, ...
Semiotic machines : software in discourse
(2008)
This study develops new theoretical and methodological approaches to the study of software as a medium of communication. This study analyses voting software, educational software, search engines, and combat and narrative ...
A novel interface for first person shooter games on personal digital assistant devices
(2008)
The main aim of this study is to enhance the playability of games on current standard PDA devices. The newly designed interface more effectively leverages current well-established devices, which solves the problem of rapidly ...
Efficient Motion Planning Algorithm for Stochastic Dynamic Systems with Constraints on Probability of Failure
(2008-03-06)
When controlling dynamic systems such as mobile robots in uncertain environments, there is a trade off between risk and reward. For example, a race car can turn a corner faster by taking a more challenging path. This paper ...
Unsupervised Distributed Feature Selection for Multi-view Object Recognition
(2008-02-17)
Object recognition accuracy can be improved when information frommultiple views is integrated, but information in each view can oftenbe highly redundant. We consider the problem of distributed objectrecognition or indexing ...
WaveScript: A Case-Study in Applying a Distributed Stream-Processing Language
(2008-01-31)
Applications that combine live data streams with embedded, parallel,and distributed processing are becoming more commonplace. WaveScriptis a domain-specific language that brings high-level, type-safe,garbage-collected ...
Transfer learning for image classification with sparse prototype representations
(2008-03-03)
To learn a new visual category from few examples, prior knowledge from unlabeled data as well as previous related categories may be useful. We develop a new method for transfer learning which exploits available unlabeled ...
Wicked Problems and Gnarly Results: Reflecting on Design and Evaluation Methods for Idiosyncratic Personal Information Management Tasks
(2008-02-10)
This paper is a case study of an artifact design and evaluation process; it is a reflection on how right thinking about design methods may at times result in sub-optimal results. Our goal has been to assess our decision ...
