Dynamic sub-GOP forward error correction code for real-time video applications
(2012)Reed-Solomon erasure codes are commonly studied as a method to protect the video streams when transmitted over unreliable networks. As a block-based error correcting code, on one hand, enlarging the block size can enhance ... -
Changes as first-class citizens: A research perspective on modern software tooling
(Association for Computing Machinery, 2017)Software must evolve to keep up with an ever-changing context, the real world. We discuss an emergent trend in software evolution research revolving around the central notion that drives evolution: Change. By reifying ... -
Fast Iterative Method with a Second-Order Implicit Difference Scheme for Time-Space Fractional Convection–Diffusion Equation
(2017)In this paper we intend to establish fast numerical approaches to solve a class of initial-boundary problem of time-space fractional convection-diffusion equations. We present a new unconditionally stable implicit difference ... -
A scalable dynamic programming scheme for the computation of optimal k-segments for ordered data
(2017)The optimal kk-segments of an ordered dataset of size nn consists of kk tuples that are obtained by merging consecutive tuples such that a given error metric is minimized. The problem is general and has been studied in ... -
Fast and Parallel Computational Techniques Applied to Numerical Modeling of RFX-mod Fusion Device
(2018)This paper presents fast computational techniques applied to modelling the RFX-mod fusion device. An integral equation model is derived for the current distribution on the active coils of the conducting structures, and the ... -
Editorial
(2014)Dear colleagues and readers, It is with great pleasure that I welcome you to the first issue of the Journal of Information Technology and Tourism that is now published by Springer. In the last issue, which was published ... -
Active learning strategies for rating elicitation in collaborative filtering: A system-wide perspective
(2013)The accuracy of collaborative-filtering recommender systems largely depends on three factors: the quality of the rating prediction algorithm, and the quantity and quality of available ratings. While research in the field ... -
Selective contextual information acquisition in travel recommender systems
(2017)Context-aware recommender systems are information filtering and decision support applications that generate recommendations by exploiting context-dependent user preference data, such as ratings augmented with the description ... -
Multiple Descriptions Based on Multirate Coding for JPEG 2000 and H.264/AVC
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)Multiple description coding (MDC) makes use of redundant representations of multimedia data to achieve resiliency. Descriptions should be generated so that the quality obtained when decoding a subset of them only depends ... -
Optimizing the deadzone width to improve the polyphase-based multiple description coding
(2014)The polyphase-based mechanism is the basis of many multiple descriptions coding schemes. Its main drawback is the inefficient exploitation of the inserted redundancy, especially when the redundancy is large. In this paper ...
