A simple continuous fabrication process for graded-index polymer optical fibers is presented that does not rely on dopants to form the refractive-index profile. A conventional melt-spinning process is followed by rapid cooling. This will result in a density gradient and finally in a refractive-index profile.
Integrated Low-Rank-Based Discriminative Feature Learning for Recognition
Feature learning plays a central role in pattern recognition. In recent years, many representation-based feature learning methods have been proposed and have achieved great success in many applications. However, these…
The BER analysis of the high altitude platforms assisted long range cooperative communication
In this paper, we propose the long range cooperative communication via high altitude platforms (HAPs). The HAPs are temporary platforms placed in the stratosphere, at the typical heights of 17-25…
Big data fusion for eHealth and Ambient Assisted Living Cloud Applications
Senior citizens may suffer from a number of diseases, including but not limited to mild dementia and cognitive disabilities, which require either the institutionalization or the constant support from care-givers.…
An Abelian group model of commutative data dependence relations for the iteration space slicing
In loop parallelization, data dependence relations are used to decide which pair of statement instances should be allocated to a same processor or should have a synchronization communication. However, in…
Generalized Extraction of Real-Time Parameters for Homogeneous Synchronous Dataflow Graphs
Many embedded multi-core systems incorporate both dataflow applications with timing constraints and traditional real-time applications. Applying real-time scheduling techniques on such systems provides real-time guarantees that all running applications will…
Forecasting of ionospheric time delays using ARMA model under Geomagnetic storm conditions
Ionospheric time delay variations are highly variable and random in the low latitude Indian region. It is a key responsible parameter for the range error in Global Positioning System (GPS)…
Spade: Decentralized orchestration of data movement and warehousing for physics experiments
The paper describes the implementation and experiences gathered from the Spade project which is a decentralized mechanism for data management that has been used in High Energy and Light Source…
Highly linear downconverting microwave photonic link based on digital post-processing
In this paper, we investigate the linearization in frequency down-converting microwave photonic link incorporating digital signal processing (DSP) technique. By acquiring the output intercept point directly from the system hardware,…
Phoneme based realtime taboo words similarity browsing system of new words using multi-lingual taboo words databases in web environments
This paper proposes the taboo words similarity browsing system which is able to assist the naming process. The proposed system in this paper analyzes new texts - new words or…
