A Unipolar/Bipolar High-Voltage Pulse Generator Based on Positive and Negative Buck-Boost DC-DC Converters Operating in Discontinuous Conduction Mode
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper presents a new high-voltage pulse generator, which is based on positive and negative buck-boost (BB) converters fed from a relatively low voltage dc supply. The proposed generator is able to generate unipolar ...
Spinel ferrite nanoparticles for H2S gas sensor
(
Springer Verlag
, 2017 , Article)
We investigate H2S gas sensors based on spinel ferrite CuFe2O4 nanoparticles prepared by the co-precipitation method. This technique is an efficient and fast technique to produce nanoparticles. Furthermore, those nanoparticles ...
The theta-complete graph Ramsey number R(θn K5) = 4n - 3 for n = 6 and n≥ 10
(
Charles Babbage Research Centre
, 2017 , Article)
For any two graphs F1 and F2, the graph Ramsey number r(F1, F2) is the smallest positive integer N with the property that every graph of at least N vertices contains F1 or its complement contains F2 as a subgraph. In this ...
The accuracy of the anatomical method for stature estimation in Black South African females
(
Elsevier
, 2017 , Article)
The anatomical method is considered the most accurate stature estimation method, but investigation has shown that it continuously underestimates stature. This underestimation is believed to be related to the use of universal ...
Synergistic effects and optimization of nitrogen and phosphorus concentrations on the growth and nutrient uptake of a freshwater Chlorella vulgaris
(
Taylor and Francis Ltd.
, 2017 , Article)
The synergistic effects and optimization of nitrogen (N) and phosphorus (P) concentrations on the growth of Chlorella vulgaris (CCAP 211/11B, CS-42) and nutrient removal have been investigated under different concentrations ...
LaCoDa: Layered connected topology for massive data centers
(
Academic Press
, 2017 , Article)
One of the fundamental challenges of existing data centers is to design a network that interconnects massive number of servers, and therefore providing an efficient and fault-tolerant routing service to upper-layer ...
Meta-analysis in evidence-based healthcare: a paradigm shift away from random effects is overdue.
(
University of Adelaide, Joanna Briggs Institute
, 2017 , Article)
Each year up to 20 000 systematic reviews and meta-analyses are published whose results influence healthcare decisions, thus making the robustness and reliability of meta-analytic methods one of the world's top clinical ...
Extended quantum cuts for unsupervised salient object extraction
(
Springer New York LLC
, 2017 , Article)
In this manuscript, an unsupervised salient object extraction algorithm is proposed for RGB and RGB-Depth images. Saliency estimation is formulated as a foreground detection problem. To this end, Quantum-Cuts (QCUT), a ...
A Full-Bridge Submodule-Based Modular Unipolar/Bipolar High-Voltage Pulse Generator with Sequential Charging of Capacitors
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
Repetitive high pulsed electric field (PEF) is an effective method to kill microorganisms and bacteria in water treatment applications. The PEF can be generated by applying high-power electromagnetic pulse across the sample ...
A Nine-Phase Six-Terminal Concentrated Single-Layer Winding Layout for High-Power Medium-Voltage Induction Machines
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper proposes a new winding layout for high-power medium-voltage nine-phase induction machines (IMs) based on a single-layer concentrated winding layout having a unity winding factor. The machine is fundamentally an ...
