Solar aided power generation from coal fired power stations: THERMSOLV software

Although the thermodynamic advantages of using solar energy to replace the bleed off steam in the regeneration system of Rankine cycle coal fired power stations has been proven theoretically, the practical techno/economic feasibility of the concept has yet to be confirmed relative to real power station applications. To investigate this concept further, a computer modelling software “THERMSOLV” was developed by Deakin University researchers, together with the support of the Victorian power industry and Australian Research Council (ARC). This newly developed software simulates the steam cycle to assess the techno/economic merit of the solar aided concept for various power station structures, locations and local electricity market conditions. Two case studies, one in Victoria Australia and one in Yunnan Province, China, have been carried out to show the application of the software. This paper reports the structure and functions of the software, and the results of the two case studies.

Utilising solar energy within conventional coal fired power stations

Although the thermodynamic advantages of using solar energy to replace the bled off steam in the regeneration system of Rankine cycle coal fired power stations has been proven theoretically, the practical techno/economic feasibility of the concept has yet to be confirmed relative to real power station applications. To investigate this concept further, computer modelling software “THERMSOLV” was specifically developed for this project at Deakin University, together with the support of the Victorian power industry and Australian Research Council (ARC). This newly developed software simulates the steam cycle to assess the techno/economic merit of the solar aided concept for various power station structures, locations and local electricity market conditions. Two case studies, one in Victoria Australia and one in Yunnan Province, China, have been carried out with the software. Chapter one of this thesis defines the aims and scope of this study. Chapter two details the literature search in the related areas for this study. The thermodynamic concept of solar aid power generation technology has been described in chapter three. In addition, thermodynamic analysis i.e. exergy/availability has been described in this chapter. The “Thermosolv” software developed in this study is detailed in chapter four with its structure, functions and operation manual included. In chapter five the outcomes of two case studies using the “Thermosolv” software are presented, with discussions and conclusions about the study in chapters 6 and 7 respectfully. The relevant recommendations are then made in chapter eight.

Political transition in Myanmar: prospects and problems

Since 2011, Myanmar has been undergoing a political transition that, in keeping with the Myanmar government's own claims, has been hailed by many previously critical countries as the start of a process of democratization. Myanmar has become a substantially more liberal country, and in particular its economy has been increasingly liberalized, away from the tight restrictions of the past. However, Myanmar's economic liberalization primarily benefits its entrenched and usually military-dominated or linked elites, while its political liberalization may be just enough to satisfy an appearance of democratization without the army giving up real power. This article looks at Myanmar's process of political liberalization set against some of the literature on political transitions, and highlights some factors that could militate against extensive reform, much less democratization. It concludes by noting that while Myanmar's military has started to step back from direct political control, it still retains ultimate state authority. © 2014 Policy Studies Organization.

Deconstructing power within a strategic information system

Strategy is a political act, and yet that has received very little attention in IS strategy research. The purpose of this paper is to explore the mixes between politics, power and strategy using a case study of implementation of a Student Administration System. This takes Strategic Information Systems out of the realm of the purely socia-technical view of information systems and moves it into a dimension which deals with the real social interactions that occur within organisations as a result of the implementation of a strategy in the form of a Student Administration System. This case study shows the power struggles, primarily by two Senior Executives and the users of the information system. The discourse behind this project was initially to create uniformity across a system therefore enabling more than 30 universities around Australia to move from a diversified system to a centralized system. It was through this resistance and through their positions that the two Senior Executives were able to create the discourse that framed many of the decisions and implementation of the system. There eventually became an acceptance that it was for the social good of the University that the Student Administration System was adopted across the University of Australia.

Application of neural networks as an auxiliary technique in the modelling of power station

Artificial neural network (NN) is an alternative way (to conventional physical or chemical based modeling technique) to solve complex ill-defined problems. Neural networks trained from historical data are able to handle nonlinear problems and to find the relationship between input data and output data when there is no obvious one between them. Neural Networks has been successfully used in control, robotic, pattern recognition, forecasting areas. This paper presents an application of neural networks in finding some key factors eg. heat loss factor in power station modeling process. In the conventional modeling of power station, these factors such as heat loss are normally determined by experience or “rule of thumb”. To get an accurate estimation of these factors special experiment needs to be carried out and is a very time consuming process. In this paper the neural networks (technique) is used to assist this difficult conventional modeling process. The historical data from a real running brown coal power station in Victoria has been used to train the neural network model and the outcomes of the trained NN model will be used to determine the factors in the conventional energy modeling of the power stations that is under the development as a part of an on-going ARC Linkage project aiming to detail modeling the internal energy flows in the power station.

Are real exchange rates nonlinear with a unit root? Evidence on PPP for Italy : a note

In this article, we apply the recently developed threshold autoregression model to examine both linearity and stationarity of Italy's real exchange rate vis--vis her six trading partner (G6) countries. Our main finding is that Italy's real exchange rate is a nonlinear process that is not characterized by a unit root process for five of six trading partner countries. This provides strong support for purchasing power parity.

Real footballers don`t eat quiche: old narratives in new times

In this article, the authors examine the way that sport acts as a contradictory and complex medium for masculinity making. The analysis illustrates the way that many discourses now unite in a cybernetic mix that offers both new opportunities and presents complex challenges for educators, coaches, and administrators. The method used combines a number of strategies and narratives pitched at the local, national, and international levels. The analysis is grounded in the game of football, although it is argued that the issues raised translate to other settings. At the same time, the authors demonstrate that large-scale, macro level analyses miss an important force working within the dynamics of masculinity making and sport, namely, peer group power. The analysis concludes with insights from a junior coach who has consciously "worked" the peer group dynamics to foster a strong sense of personal and group responsibility.

Exploring the increasing role of the real estate sector in the Chinese economy : 1997-2002

The Chinese government launched a series of real estate reform policies in 1998, which further changed the real estate sector from socialist plan-oriented to modern marketoriented. This paper compares the role of the real estate sector in the Chinese economy in years 1997 and 2002 by using the recently published input-output OECD database. Results verify that the Chinese real estate sector played an increasing role in the Chinese economy with higher contributions and stronger push and pull power in 2002 than those in 1997. However, compared with other countries, especially for some OECD countries, the Chinese real estate sector has a relative lower contribution.

Are bilateral real exchange rates stationary? Evidence from Lagrange multiplier unit root tests for India

The paper examines the stationarity of India’s real exchange rate vis-a` -vis 16 of its major trading partner countries for the period 1960–2000. Application of the conventional ADF unit root test, the Lagrange multiplier (LM) unit root test with one structural break, and the LM unit root test with two structural breaks provides evidence that India’s exchange rate vis-a` -vis 15 out of 16 countries is stationary, implying support for purchasing power parity.

The purchasing power parity revisited : new evidence for 16 OECD countries from panel unit root tests with structural breaks

In this paper, we apply a range of univariate unit root tests including the Lagrangian multiplier (LM) univariate and panel unit root tests to examine PPP for 16 OECD countries. In addition to incorporating structural breaks in the univariate exchange rate series, we also incorporate structural breaks in the panel exchange rate models. Our main finding from univariate tests, with and without structural breaks and panel LM test with one break, is that real exchange rates are not stationary, inconsistent with PPP hypothesis. However, when we incorporate two structural breaks in the univariate LM test, for most countries we find that real exchange rates are stationary. Moreover, we obtain overwhelming support for PPP when we apply panel LM unit root tests with two structural breaks.

New evidence on purchasing power parity from 17 OECD countries

There is a large literature that investigates whether or not real exchange rates are stationary in an attempt to unravel support for purchasing power parity (PPP). At best, the empirical results are mixed. This paper applies a unit root test that allows for a simultaneous structural break in the intercept and slope, shown by Sen (2003) to minimize power distortions, to examine PPP for 17 OECD countries. Our results on PPP are mixed. When the real exchange rate is based on the US dollar, evidence is found of PPP for only France, Portugal and Denmark. When the real exchange rate is based on the Deutschmark, we find evidence of PPP for Austria, Belgium, Norway, Spain, Netherlands, Switzerland, and Denmark.
