Optimization for Compact and High Output LED-Based Optical Wireless Power Transmission System

open access: yesPhotonics, 2021
Optical wireless power transmission (OWPT) is a technology that supplies energy remotely. Due to the great advantages of long transmission distances, high directionality, no electromagnetic interference noise, and loose safety regulations, light emitting

Slicing and dicing the information space using local contexts [PDF]

open access: yes, 2006
In recent years there has been growing interest in faceted grouping of documents for Interactive Information Retrieval (IIR). It is suggested that faceted grouping can offer a flexible way of browsing a collection compared to clustering.

Experimental Methods in IIR: The Tension between Rigour and Ethics in Studies Involving Users with Dyslexia [PDF]

open access: yes, 2019
Designing user studies in the interactive information retrieval (IIR) paradigm on people with impairments may sometimes require different methodological considerations than for other users.

Validating simulated interaction for retrieval evaluation [PDF]

open access: yes, 2017
A searcher’s interaction with a retrieval system consists of actions such as query formulation, search result list interaction and document interaction. The simulation of searcher interaction has recently gained momentum in the analysis and evaluation of

Role of anticausal inverses in multirate filter-banks. I. System-theoretic fundamentals [PDF]

open access: yes, 1995
In a maximally decimated filter bank with identical decimation ratios for all channels, the perfect reconstructibility property and the nature of reconstruction filters (causality, stability, FIR property, and so on) depend on the properties of the ...

On the theory and design of a class of PR uniform and recombination nonuniform causal-Stable IIR cosine modulated filter banks [PDF]

open access: yes, 2008
This paper studies the theory and design of a class of perfect reconstruction (PR) uniform causal-stable infinite-impulse response (IIR) cosine modulated filter banks (CMFBs).

On arbitrary-level IIR and FIR filters [PDF]

open access: yes, 1990
A recently published method for designing IIR (infinite-impulse-response) digital filters with multilevel magnitude responses is reinterpreted from a different viewpoint.

Two variants of the IIR spline adaptive filter for combating impulsive noise

open access: yesEURASIP Journal on Advances in Signal Processing, 2019
It has been pointed out that the nonlinear spline adaptive filter (SAF) is appealing for modeling nonlinear systems with good performance and low computational burden.

Simple estimation of incident HIV infection rates in notification cohorts based on window periods of algorithms for evaluation of line-immunoassay result patterns. [PDF]

open access: yesPLoS ONE, 2013
Tests for recent infections (TRIs) are important for HIV surveillance. We have shown that a patient's antibody pattern in a confirmatory line immunoassay (Inno-Lia) also yields information on time since infection. We have published algorithms which, with

Resveratrol Suppresses Gut-Derived NLRP3 Inflammasome Partly through Stabilizing Mast Cells in a Rat Model

open access: yesMediators of Inflammation, 2018
Background. Inflammatory responses induced by intestinal ischemia-reperfusion (IIR) lead to serious systemic organ dysfunction and pose a challenge for current treatment.
