Magnified Time-Domain Ghost Imaging
Piotr Ryczkowski, Margaux Barbier, Ari T. Friberg +2
Ghost imaging allows to image an object without directly seeing this object. Origi- nally demonstrated in the spatial domain using classical or entangled-photon sources, it was rec…
Parallel Digital Predistortion Design on Mobile GPU and Embedded Multicore CPU for Mobile Transmitters
Kaipeng Li, Amanullah Ghazi, Chance Tarver +6
Digital predistortion (DPD) is a widely adopted baseband processing technique in current radio transmitters. While DPD can effectively suppress unwanted spurious spectrum emissions…
Complexity of Rainbow Vertex Connectivity Problems for Restricted Graph Classes
Juho Lauri
A path in a vertex-colored graph is \emph{vertex rainbow} if all of its internal vertices have a distinct color. The graph is said to be \emph{rainbow vertex connected} if…
A hardness result and new algorithm for the longest common palindromic subsequence problem
Shunsuke Inenaga, Heikki Hyyrö
The 2-LCPS problem, first introduced by Chowdhury et al. [Fundam. Inform., 129(4):329-340, 2014], asks one to compute (the length of) a longest palindromic common subsequence betwe…
pocl: A Performance-Portable OpenCL Implementation
Pekka Jääskeläinen, Carlos Sánchez de La Lama, Erik Schnetter +3
OpenCL is a standard for parallel programming of heterogeneous systems. The benefits of a common programming standard are clear; multiple vendors can provide support for applicatio…
Wirelessly Powered Urban Crowd Sensing over Wearables: Trading Energy for Data
Olga Galinina, Konstantin Mikhaylov, Kaibin Huang +2
In this article, we put forward the mobile crowd sensing paradigm based on ubiquitous wearable devices carried by human users. The key challenge for mass user involvement into pros…
