Role of green micro-credit in creating livelihood options and women's empowerment in a Bangladesh wetland

Yeasmin, Lubna 12 April 2012 (has links)
The research examines the role of green micro-credit in creating livelihood options and women’s empowerment in Hakaluki haor. The role of green micro-credit is found important in creating livelihood options. The more livelihood options that the borrowers have, the less they are vulnerable to crises. Results related to women’s empowerment were diverse and complex. Women’s empowerment can mean different things to different individuals. Woman’s restricted mobility, low skill-set, and domestic workload impeded them from investing and using green micro-credit. Borrowers were found to be innovative, and had the capacity to maximize economic benefit from the green enterprises. The impacts of green micro-credit on environmental sustainability are yet to be assessed. Green micro-credit has not been running long enough. For firmer conclusions, a longitudinal study of sustainability and empowerment under green micro-credit would be needed.

Application of Gaussian Moment Closure Methods to Three-Dimensional Micro-Scale Flows

Lam, Christopher 25 August 2011 (has links)
A parallel, block-based, three-dimensional, hexahedral finite-volume scheme with adaptive mesh refinement has been developed for the solution of the 10-moment Gaussian closure for the modelling of fully three-dimensional micro-scale, non-equilibrium flows. The Gaussian closure has been shown to be a more effective tool for modelling rarefied flows lying within the transition regime than the Navier-Stokes equations, which encounter mathematical difficulties approaching free-molecular flows, and is computationally less expensive than particle-based methods for flows approaching the continuum limit. The hyperbolic nature of the moment equations is computationally attractive and the generalized transport equations can be solved in an accurate and efficient manner using Godunov-type finite-volume schemes as considered here. Details are given of the Gaussian closure, along with extensions for diatomic gases and slip-flow boundaries. Numerical results for several canonical flows demonstrate the potential of these moment closures and the parallel solution scheme for accurately predicting fully three-dimensional non-equilibrium flow behaviour.

A method for concurrently optimising the weight and response of wound field direct current motors.

El Aker, Mounzer Nizar January 2004 (has links)
Title page, abstract and table of contents only. The complete thesis in print form is available from the University of Adelaide Library. / Compact, lightweight and responsive direct current (DC) motors are desirable in industries requiring precise control operations such as those using robotic and micro-robotic devices. Permanent magnet (PM) motors have been used exclusively in these industries, in recent years, because they meet these requirements. However, their speed range and output torque are limited compared to wound field direct current (WF DC) motors and this renders them far less effective than WF DC motors in terms of handling load disturbances. So far, only one study by Reyer and Papalambros (1999) has investigated a method for concurrently optimising the weight and response of WF DC motors with, in this case, proportional, integral and derivative (PID) controllers. However, the documentation provided in their study suggests that their optimised WF motor was defective in terms of efficiency, speed and shape. The aim of the present study was to develop Reyer and Papalambros's method in a way that overcomes the problems that arose. To do this, first an investigation into Reyer and Papalambros's mathematical model was conducted, and their equality and inequality equations have been modified. Second, their optimisation model has been represented by its transfer functions. Third, their model's parameters and variables have been reconsidered. Finally, the WF motor/controller system was discretely optimised. Following these developments, the new method was used to optimise the weight and response of a motor/controller system capable of driving a 6 Nm torque in MATLAB to illustrate the developed method and compare its outcome with that achieved by Reyer and Papalambros in 1999. The comparison indicated that the method developed here is superior and the weight and response of the system optimised by this current study outperforms the one developed by Reyer and Papalambros. To confirm the validity of the developed weight optimisation model, the weight of a 50 watt WF DC prototype motor was partially optimised experimentally. This resulted in the weight of this motor being successfully reduced. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1104468 / Thesis (M.Eng.Sc.) -- University of Adelaide, School of Mechanical Engineering, 2004
