Deadbeat control with multi-sampling compensation for medium-voltage motor drives by cascaded multi-cell inverter using FPGA based hardware controller
(
IEEE
, 2011 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a deadbeat control combined with a multi-sampling ...
Evaluating greywater and A/C condensate daily volume and water quality in urban settings
(
American Society of Agricultural and Biological Engineers
, 2011 , Conference Paper)
Due to increasing water demand as a result of population growth and improvement in living standards, many countries with arid climate are already facing water shortages that are being met by expensive desalination projects. ...
A/C condensate for water reuse: An approach towards environmental sustainability in Doha
(
American Society of Agricultural and Biological Engineers
, 2012 , Conference Paper)
A/C Condensate is a relatively untapped alternative source of water that might be readily available especially in hot arid climates. The objective of this study is to establish the feasibility of the A/C condensate as the ...
Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)
The main focus of this study is on the near field flow and mixing characteristics of the thermal
wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling
systems of power ...
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)
In this study, a new finite volume method is developed for shallow water equations on a rotating
frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or
numerical damping for ...
Adaptive and unequal probability survey designs for environmental management
(
The Modelling and Simulation Society of Australia and New Zealand Inc
, 2011 , Conference Paper)
Designing an efficient large-area survey is a challenge, especially in environmental science when many populations are rare and clustered. Adaptive and unequal probability sampling designs are appealing when populations ...
Multi-species attributes as the condition for adaptive sampling of rare species using two-stage sequential sampling with an auxiliary variable
(
The Modelling and Simulation Society of Australia and New Zealand Inc
, 2011 , Conference Paper)
Assessing populations of rare species is challenging because of the large effort required to locate patches of occupied habitat and achieve precise estimates of density and abundance. The presence of a rare species has ...
Gravitational weighted fuzzy c-means with application on multispectral image segmentation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper presents a novel clustering approach based on the classic Fuzzy c-means algorithm. The approach is inspired from the concept of interaction between objects in physics. Each data point is regarded as a particle. ...
A FCM and SURF based algorithm for segmentation of multispectral face images
(
IEEE
, 2013 , Conference Paper)
In this paper, we propose a novel clustering algorithm based on Fuzzy C-Means (FCM) and Speeded-Up Robust Feature (SURF) for multispectral image segmentation. In the experiments, color images and multispectral images from ...
Cluster validity index based on n-sphere
(
IEEE
, 2014 , Conference Paper)
In this paper, we propose a new cluster validity index (CVI) based on geometrical shape. Classic CVIs are based on a combination of separation and compactness measures and may include a measure of overlap between clusters. ...
