Efficient Similarity Join and Search on Multi-Attribute Data
Similarity Search Similarity Join Multi-Attribute Data
2016/1/22
In this paper we study similarity join and search on multi-attribute data. Traditional methods on single-attribute data have pruning power only on single attributes and cannot efficiently support mult...
An Efficient Feedback Coding Scheme With Low Error Probability for Discrete Memoryless Channels
Feedback discrete memoryless channel error exponent
2015/8/17
Existing fixed-length feedback communication schemes are either specialized to particular channels (Schalkwijk–Kailath, Horstein), or apply to general channels but either have high coding comple...

Energy-efficient Scheduling of Packet Transmissions over Wireless Networks
Energy-effi cient Scheduling Packet Transmissions Wireless Networks
2015/8/17
The paper develops algorithms for minimizing the energy required to transmit packets in a wireless environment. It is motivated by the following observation: In many channel coding schemes it is possi...
Energy-efficient Transmission over a Wireless Link via Lazy Packet Scheduling
cient Transmission Wireless Link Lazy Packet Scheduling
2015/8/17
We then devise a lazy online algorithm that varies transmission times according to backlog and show that it is more energy efficient than a deterministic schedule that guarantees stability for t...
Identity Based Encryption (IBE) systems are often constructed using bilinear maps (a.k.a. pairings) on elliptic curves. One exception is an elegant system due to Cocks which builds an IBE based on the...
Multiparty Key Exchange, Efficient Traitor Tracing, and More from Indistinguishability Obfuscation
Multiparty Key Exchange Effi cient Traitor Tracing
2015/8/5
Our traitor tracing system is fully collusion resistant with short ciphertexts, secret keys,
and public key. Ciphertext size is logarithmic in the number of users and secret key size is
independent ...

A mass-conserving multi-tracer effi cient transport scheme
2014/12/12
In this paper a new advection scheme for the
online coupled chemical–weather prediction model EnviroHIRLAM is presented.
Nearly Total Solar Absorption in Ultrathin Nanostructured Iron Oxide for Efficient Photoelectrochemical Water Splitting
photon management antirefl ection light trapping nanocone hematite photoelectrochemical cells
2015/8/6
We demonstrate using first-principles full-field electromagnetic simulations that nearly total above-band-gap solar absorption can be achieved in ultra-thin-film iron oxide photoanod...
Dislocated Double-Layer Metal Gratings: An Efficient Unidirectional Coupler
Unidirectional coupler surface plasmon polariton metal grating Wood’s anomaly
2015/8/6
We propose theoretically and demonstrate experimentally a dislocated double-layer metal grating structure, which operates as a unidirectional coupler capable of launching surface plasmon polaritons in...
Nanodome Solar Cells with Efficient Light Management and Self-Cleaning
Nanocone nanodome solar cell light trapping photovoltaics
2015/8/10
Here for the first time, we demonstrate novel nanodome solar cells, which have periodic nanoscale modulation for all layers from the bottom substrate, through the active absorber to the top tran...

The explosion of multimedia data necessitates effective and efficient ways for us to get access to our desired ones. In this article,we draw an analogy between image retrieval and text retrieval...
Efficient Multiple-Description Image Coding Using Directional Lifting-Based Transform
Image compression lifting-based transform multiple-description coding (MDC) wavelet
2013/7/17
This paper proposes an efficient two-description image coding technique. The two side descriptions of an image are generated by quincunx subsampling. The decoding from any side description is do...
