Factors Affecting Effective Project Cost Management: The Case of Nashcon Construction PLC
Creators: name: Silassie, Sirgute
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: A project is successful only if it is completed within the approved time, quality and budget. Studies show that most projects in Ethiopia are not completed on time because of cost and schedule overrun due to lack of proper project cost management. Managers in the construction industry therefore need to focus on project cost management in order to attain project success. This research is done on a company called Nashcon Construction PLC. The main objective of the research is to improve the company's Project Cost Management process by identifying factors which affect the effectiveness of the process most. The researcher employed a mixed research approach to investigate the problem under study. Both quantitative and qualitative data was collected through questionnaire and interview from personnel's in Nashcon Construction PLC. The study concepts were developed through literature survey that enables to find out the variables. Furthermore, In order to obtain more insight on the cases, the study used review of document in the company and also an in-depth interview was conducted to assess the current status of the company's project cost management implementation. The research result shows that though Nashcon Construction PLC is implementing the three cost management components (Cost Estimation, Cost Budgeting, and Cost Controlling) currently, its cost management system is poor and needs improvement. After data analysis it was discovered that the company's cost management process is affected more by factors related to Cost Budgeting this shows that the company has of poor cost budgeting system. Furthermore poor scope definition, not updating budget after variation of changes, inaccurate cost budgeting, incomplete design, poor WBS design, material price fluctuation, allowance of numerous variation during project implementation, inaccurate/impractical schedule, poor allocation of costs, failure to site investigation, change in schedule and construction methods, not having a risk register are identified as factors which affect the cost management process of Nashcon Construction PLC. Finally, based on the analysis of the results, recommendations have been proposed to improve the current project cost management of the company.

description: We study the production of polarized $Λ$ hyperon in semi-inclusive deep inelastic scattering off an unpolarized target. We include the cases in which the $Λ$ hyperon is longitudinally polarized or transversely polarized, and in which the lepton beam is unpolarized or longitudinally polarized. Within the framework of the transverse momentum dependent factorization, we take into account the complete decomposition of the parton correlator for fragmentation up to twist-3. We present the cross section of the process to order $1/Q$. The expressions of the polarized structure functions, which may give rise to various spin asymmetries, are also given.

description: In current modern dynamic world, data centers have become very complex and have completely integrated themselves into every aspect of their implied organization. Business organizations require Core banking applications to be available at any part of the day or night. These organizations have realized that with centralized computing and highly available components, their technological presence with customers can be greatly enhanced. Today, many organizations largely depend on projects to achieve their strategic objectives. Accordingly, CBE data center project invested huge capital and tried to implement project. However, the project has faced major challenges during project implementation. The purpose of this study is to identify the challenges of Data center project implementation in the Commercial Bank of Ethiopia. Descriptive research approach is selected for this study. Data were collected for the study using questionnaire, documentation, physical observation and interview. The collected Data was analyzed and interpreted using descriptive analysis technique. The top four challenges are power and cooling challenges, lack of SLA contractors and service providers, management influence on project team site and space decision, and internal constraints or factors that affect the performance and operation of the project. The research findings will give insight for those organizations in Ethiopia which plan to construct new data center by addressing the challenges properly. Based on this finding, recommendations are made to overcome these challenges. This research helps to identify the major challenges in implementation of the data center projects and what constraints are on hand to construct new data Centre in commercial Bank of Ethiopia.

description: We consider a model of an electron in a crystal moving under the influence of an external electric field: Schrödinger's equation with a potential which is the sum of a periodic function and a general smooth function. We identify two dimensionless parameters: (re-scaled) Planck's constant and the ratio of the lattice spacing to the scale of variation of the external potential. We consider the special case where both parameters are equal and denote this parameter $ε$. In the limit $ε\downarrow 0$, we prove the existence of solutions known as semiclassical wavepackets which are asymptotic up to `Ehrenfest time' $t \sim \ln 1/ε$. To leading order, the center of mass and average quasi-momentum of these solutions evolve along trajectories generated by the classical Hamiltonian given by the sum of the Bloch band energy and the external potential. We then derive all corrections to the evolution of these observables proportional to $ε$. The corrections depend on the gauge-invariant Berry curvature of the Bloch band, and a coupling to the evolution of the wave-packet envelope which satisfies Schrödinger's equation with a time-dependent harmonic oscillator Hamiltonian. This infinite dimensional coupled `particle-field' system may be derived from an `extended' $ε$-dependent Hamiltonian. It is known that such coupling of observables (discrete particle-like degrees of freedom) to the wave-envelope (continuum field-like degrees of freedom) can have a significant impact on the overall dynamics.

description: We consider plasma consisting of electrons and ions in presence of a background neutrino gas and develop the magneto hydrodynamic equations for the system. We show that electron neutrino interaction can induce vorticity in the plasma even in the absence of any electromagnetic perturbations if the background neutrino density is left-right asymmetric. This induced vorticity support a new kind of Alfvén wave whose velocity depends on both the external magnetic field and on the neutrino asymmetry. The normal mode analysis show that in the presence of neutrino background the Alfvén waves can have different velocities. We also discuss our results in the context of dense astrophysical plasma such as magnetars and show that the difference in the Alfvén velocities can be used to explain the observed pulsar kick. We discuss also the relativistic generalization of electron fluid in presence of asymmetric neutrino background.

description: We present firstly equation of motion for the photon coupled to Weyl tensor in a Kerr black hole spacetime and then study further the corresponding strong gravitational lensing. We find that black hole rotation makes propagation of the coupled photons more complicated, which brings some new features for physical quantities including the marginally circular photon orbit, the deflection angle, the observational gravitational lensing variables and the time delay between two relativistic images. There is a critical value of the coupling parameter for existence of the marginally circular photon orbit outside the event horizon, which depends on the rotation parameter of black hole and the polarization direction of photons. As the value of coupling parameter is near the critical value, we find that the marginally circular photon orbit for the retrograde photon increases with the rotation parameter, which modifies a common feature of the marginally circular photon orbit in a rotating black hole spacetime since it always decreases monotonously with the rotation parameter in the case without Weyl coupling. Combining with the supermassive central object in our Galaxy, we estimated the observables including time delays between the relativistic images in the strong gravitational lensing as the photons couple to Weyl tensor.

description: We develop an empirical behavioural order-driven (EBOD) model, which consists of an order placement process and an order cancellation process. Price limit rules are introduced in the definition of relative price. The order placement process is determined by several empirical regularities: the long memory in order directions, the long memory in relative prices, the asymmetric distribution of relative prices, and the nonlinear dependence of the average order size and its standard deviation on the relative price. Order cancellation follows a Poisson process with the arrival rate determined from real data and the cancelled order is determined according to the empirical distributions of relative price level and relative position at the same price level. All these ingredients of the model are derived based on the empirical microscopic regularities in the order flows of stocks on the Shenzhen Stock Exchange. The model is able to produce the main stylized facts in real markets. Computational experiments uncover that asymmetric setting of price limits will cause the stock price diverging exponentially when the up price limit is higher than the down price limit and vanishing vice versus. We also find that asymmetric price limits have influences on stylized facts. Our EBOD model provides a suitable computational experiment platform for academics, market participants and policy makers.

description: Geoscience Australia’s Exploring for the Future program (EFTF) provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. The Australian Passive Seismic Array Project (AusArray) program developed from a long history of passive seismic imaging in Australia involving many contributors. Building on this history, the Australian Government (EFTF), academia and state governments have united around AusArray. The objective is a standardised and quality controlled national passive seismic data coverage and an updatable national seismic velocity model framework that can be used as a background for higher-resolution studies. The AusArray passive seismic data are supplemented with active seismic data that can provide P-wave and S-wave velocity information for the near surface down to about 50 m depth. This near-surface velocity data will provide constraints for some AusArray passive seismic data modelling to obtain more reliable depth models. This document details the active seismic data acquisition using TROMINO® three-axis broadband seismometers using a wireless trigger and hammer source. Equipment packing, field operations, data extraction and preparation, and Multichannel Analysis of Surface Waves (MASW) modelling are described.

description: The Hermean average perihelion rate $\dotω^\mathrm{2PN}$, calculated to the second post-Newtonian (2PN) order with the Gauss perturbing equations and the osculating Keplerian orbital elements, ranges from $-18$ to $-4$ microarcseconds per century $\left(μ\mathrm{as\,cty}^{-1}\right)$, depending on the true anomaly at epoch $f_0$. It is the sum of four contributions: one of them is the direct consequence of the 2PN acceleration entering the equations of motion, while the other three are indirect effects of the 1PN component of the Sun's gravitational field. An evaluation of the merely formal uncertainty of the experimental Mercury's perihelion rate $\dotω_\mathrm{exp}$ recently published by the present author, based on 51 years of radiotechnical data processed with the EPM2017 planetary ephemerides by the astronomers E.V. Pitjeva and N.P. Pitjev, is $σ_{\dotω_\mathrm{exp}}\simeq 8\,μ\mathrm{as\,cty}^{-1}$, corresponding to a relative accuracy of $2\times 10^{-7}$ for the combination $\left(2 + 2γ- β\right)/3$ of the PPN parameters $β$ and $γ$ scaling the well known 1PN perihelion precession. In fact, the realistic uncertainty may be up to $\simeq 10-50$ times larger, despite reprocessing the now available raw data of the former MESSENGER mission with a recent improved solar corona model should ameliorate our knowledge of the Hermean orbit. The BepiColombo spacecraft, currently en route to Mercury, might reach a $\simeq 10^{-7}$ accuracy level in constraining $β$ and $γ$ in an extended mission, despite $\simeq 10^{-6}$ seems more likely according to most of the simulations currently available in the literature. Thus, it might be that in the not too distant future it will be necessary to include the 2PN acceleration in the Solar System's dynamics as well.

On conjugacy separability of fibre products

description: In this paper we study conjugacy separability of subdirect products of two free (or hyperbolic) groups. We establish necessary and sufficient criteria and apply them to fibre products to produce a finitely presented group $G_1$ in which all finite index subgroups are conjugacy separable, but which has an index $2$ overgroup that is not conjugacy separable. Conversely, we construct a finitely presented group $G_2$ which has a non-conjugacy separable subgroup of index $2$ such that every finite index normal overgroup of $G_2$ is conjugacy separable. The normality of the overgroup is essential in the last example, as such a group $G_2$ will always posses an index $3$ overgroup that is not conjugacy separable. Finally, we characterize $p$-conjugacy separable subdirect products of two free groups, where $p$ is a prime. We show that fibre products provide a natural correspondence between residually finite $p$-groups and $p$-conjugacy separable subdirect products of two non-abelian free groups. As a consequence, we deduce that the open question about the existence of an infinite finitely presented residually finite $p$-group is equivalent to the question about the existence of a finitely generated $p$-conjugacy separable full subdirect product of infinite index in the direct product of two free groups.

description: We exhibit a method to use continued fractions in function fields to find new families of hyperelliptic curves over the rationals with given torsion order in their Jacobians. To show the utility of the method, we exhibit a new infinite family of curves over $\mathbb Q$ with genus two whose Jacobians have torsion order eleven. {\bf In this updated version, we correct an error in the initial paper:} The ``new" family claimed in the original Theorem~1 was pointed out by Professor D.~Lorenzini to have elements isomorphic with elements in Flynn's family (as defined in the paper); his guess that the families were the same up to element-wise isomorphism is correct. Here, we give a family that is new; the old proof, now free of clerical error (we had replaced our $g_u(x)$ by $1+g_u(x)$ when determining Igusa invariants), holds. Changes from the original version are flagged by {\color{red} UPDATED}; there are three of these: the new family $g_u(x)$; its partial quotients; the way to solve in the naive approach to find this new family. (We also added an acknowledgement section.) Finally, as an appendix we include a PDF export of Maple calculations verifying our correction.

description: Given an edge-coloring of a graph $G$, we associate to every vertex $v$ of $G$ the set of colors appearing on the edges incident with $v$. The palette index of $G$ is defined as the minimum number of such distinct sets, taken over all possible edge-colorings of $G$. A graph with a small palette index admits an edge-coloring which can be locally considered to be almost symmetric, since few different sets of colors appear around its vertices. Graphs with palette index $1$ are $r$-regular graphs admitting an $r$-edge-coloring, while regular graphs with palette index $2$ do not exist. Here, we characterize all graphs with palette index either $2$ or $3$ in terms of the existence of suitable decompositions in regular subgraphs. As a corollary, we obtain a complete characterization of regular graphs with palette index $3$.

description: We consider a model of an electron in a crystal moving under the influence of an external electric field: Schroedinger's equation in one spatial dimension with a potential which is the sum of a periodic function $V$ and a smooth function $W$. We assume that the period of $V$ is much shorter than the scale of variation of $W$ and denote the ratio of these scales by $ε$. We consider the dynamics of $\textit{semiclassical wavepacket}$ asymptotic (in the limit $ε\downarrow 0$) solutions which are spectrally localized near to a $\textit{crossing}$ of two Bloch band dispersion functions of the periodic operator $- \frac{1}{2} \partial_z^2 + V(z)$. We show that the dynamics is qualitatively different from the case where bands are well-separated: at the time the wavepacket is incident on the band crossing, a second wavepacket is `excited' which has $\textit{opposite}$ group velocity to the incident wavepacket. We then show that our result is consistent with the solution of a `Landau-Zener'-type model.

description: BTZ black holes are excellent laboratories for studying black hole thermodynamics which is a bridge between classical general relativity and quantum nature of gravitation. In addition, three-dimensional gravity could have equipped us for exploring some of the ideas behind the two dimensional conformal field theory based on the $AdS_{3}/CFT_{2}$. Considering the significant interests in these regards, we examine charged BTZ black holes. We consider the system contains massive gravity with energy dependent spacetime to enrich the results. In order to make high curvature (energy) BTZ black holes more realistic, we modify the theory by energy dependent constants. We investigate thermodynamic properties of the solutions by calculating heat capacity and free energy. We also analyze thermal stability and study the possibility of Hawking-Page phase transition. At last, we study geometrical thermodynamics of these black holes and compare the results of various approaches.

description: Model free tests for constant parameters often fail to detect structural changes in high dimensions. In practice, this corresponds to a portfolio with many assets and a reasonable long time series. We reduce the dimensionality of the problem by looking a compressed panel of time series obtained by cluster analysis and the principal components of the data. Using our methodology we are able to extend a test for a constant correlation matrix from a sub portfolio to whole indices and exemplify the procedure with the EuroStoxx index.

For instance, two temperature-driven Lifshitz transitions were inferred to exist in the Dirac nodal-line semimetal ZrSiSe, based on two-band model analysis of the Hall magnetoconductivities where the second band exhibits a change in the carrier type from holes to electrons when the temperature decreases below T = 106 K and a dip is observed in the mobility versus temperature curve at T = 80 K. Here, we revisit the experiments and two-band model analysis on ZrSiSe. We show that the anomalies in the second band may be spurious, because the first band dominates the Hall magnetoconductivities at T > 80 K, making the carrier type and mobility obtained for the second band from the two-band model analysis unreliable. That is, care must be taken in interpreting these anomalies as evidences for temperature-driven Lifshitz transitions. Our skepticism on the existence of such phase transitions in ZrSiSe is further supported by the validation of the Kohler's rule for magnetoresistances at temperatures below 180 K. This work showcases potential issues in interpreting anomalies in the temperature dependence of the carrier density and mobility derived from the analysis of magnetoconductivities or magnetoresistivities using the conventional two-band model.
title: It Was So, It Was Not So: The Use of Fairy Tale in the Fiction of Angela Carter and Salman Rushdie

description: This thesis explores the use made of fairy tales by two contemporary writers, Angela Carter and Salman Rushdie. Its aim is to investigate the ways in which fairy tale has enabled them to formulate and further their political positions. In Carter's case I suggest that the fairy tale has enabled her to explore and revise the roles played by women in society. In Rushdie's case I suggest that the fairy tale has provided a means by which he can investigate issues of cultural identity, and also functions as a tool with which ethnocentric assumptions can be challenged. By focusing upon their work I attempt to identify a specific and dominant strain in the contemporary appropriation of fairy tale that can be summarised briefly here as the use of fairy tale in fiction that aims to make statements in the field of identity politics. I concentrate, in Carter's case, upon The Bloody Chamber, Nights at the Circus and Wise Children. In Rushdie's case I look at the work in which he explores the concept of fairy tale most explicitly, Haroun and the Sea of Stories, and then I look in more detail at his use of The Arabian Nights in Midnight's Children and The Satanic Verses. By way of conclusion I suggest that they both use fairy tale as a tentative but nonetheless productive means of outlining utopian solutions to social problems.

description: LuFe$_4$Ge$_2$ crystallizes in the ZrFe$_4$Si$_2$-type structure, hosting chains of Fe-tetrahedra giving rise to geometric frustration and low-dimensionality. The compound orders antiferromagnetically at around 36 K accompanied by a simultaneous structural transition from a tetragonal to an orthorhombic phase. The hydrostatic pressure dependence of the magnetic and structural transitions is investigated using electrical-transport, ac magnetic-susceptibility, ac calorimetry, M$\ddot{\rm o}$ssbauer, muon-spin relaxation ($μ$SR), and x-ray diffraction measurements. External pressure suppresses the first-order transition to the antiferromagnetic phase (AFM1) around 1.8 GPa. The structural transition is largely unaffected by pressure and remains between 30 to 35 K for pressures up to 2 GPa. A second antiferromagnetic phase (AFM2) is observed at higher pressures. The transition from the paramagnetic to the AFM2 phase is of second-order nature and appears to be connected to the structural transition. The magnetic volume fraction obtained from $μ$SR and M$\ddot{\rm o}$ssbauer measurements reveal that the entire sample undergoes magnetic ordering in both magnetic phases. In addition, similar low-temperature muon-precession frequencies in AFM1 and AFM2 phases point at similar ordered moments and magnetic structures in both phases. Our results further indicate enhanced magnetic fluctuations in the pressure induced AFM2 phase. The experimental observations together with density functional theory calculations suggest that the magnetic and structural order parameters in LuFe$_4$Ge$_2$ are linked by magnetic frustration, causing the simultaneous magneto-structural transition.

description: We study methods for transforming valued constraint satisfaction problems (VCSPs) to binary VCSPs. First, we show that the standard dual encoding preserves many aspects of the algebraic properties that capture the computational complexity of VCSPs. Second, we extend the reduction of CSPs to binary CSPs described by Bulin et al. [LMCS'15] to VCSPs. This reduction establishes that VCSPs over a fixed valued constraint language are polynomial-time equivalent to Minimum-Cost Homomorphism Problems over a fixed digraph.

Law and policy of the Murray-Darling Basin

Publisher: name: La Trobe
Year: 2023

description: Submission note: Thesis submitted in total fulfilment of the requirements for the degree of Doctor of Juridical Science to the La Trobe Law School, La Trobe University, Victoria.

This thesis explores the discrepancy between what is needed to achieve sustainable use of water in the Murray-Darling Basin (MDB), and what has been done, and between the aspirations embodied in legislation and the realities surrounding their implementation. To demonstrate this the thesis documents short-term social and economic federal and state government action in response to resistance by irrigator groups to the implementation of sustainability measures. The thesis looks at tensions surrounding the competing approaches of prioritising the environment versus the triple bottom line and discusses the questionable lawfulness of the Basin Plan having regard to the basis upon which it was prepared. The thesis will analyse why irrigator groups resisted the Basin Plan and why it was always likely that their shared interests would prevail over environmentalism. The thesis argues that environmental sustainability is compatible with a conservative view of property rights and that the feasibility of a sustainable MDB depends upon a duty to pay compensation to irrigators adversely affected by the Basin Plan.

description: This paper proposes semi-analytical methods to obtain the local permeability for granular soils based on indirect measurements of the local porosity profile in a large coaxial cell permeameter using spatial time-domain reflectometry. The porosity profile is used to obtain the local permeability using the modified Kozeny-Carman and Katz-Thompson equations, which incorporated an effective particle diameter that accounted for particle migration within the permeameter. The profiles of the local permeability obtained from the proposed methods are compared with experimentally obtained permeability distributions using pressure measurements and flow rate. The permeabilities obtained with the proposed methods are comparable with the experimentally obtained permeabilities and are within one order of magnitude deviation, which is an acceptable range for practical applications.

Extraction, characterization and optimization of castor oil from Castor seeds for production of synthetic detergent

Year: 2016

description: Non-biodegradability process and non-solubility of mineral oil soap and synthetic detergent products cause to pollute fresh tap water. To overcome this problem replacing of the raw material of mineral oil by vegetable oil is the possible solution. Therefore; the objective of this study was extraction and optimization of castor oil from Castor seed for production of synthetic detergent. The extraction was carried out using soxhlet extraction units. In the soxhlet extraction a n-hexane was chosen to determine the effect of time and particle size on yield of the extraction oil. For the soxhlet extraction, the minimum oil yield has been determined as 24.7% after the extraction time of 2hours with particle size of 4mm and maximum oil yield 49.34% was found at the extraction time of 6hours in a particle size ranges from 2.55mm. Therefore, increasing extraction time and decreasing particle size will increase the amount of oil extracted. The research also revealed some properties of castor oil in terms of values obtained by the determination of saponification value of 172.4oil as proportional to the standard saponification of value of 177oil and the acid value (AV) of 11.22 maximum than the standard acid value of 10. Other parameters used to determine the quality of castor oil include specific gravity and pH tests. For the agitated mixing, the best quality (1.8cm of height foamability, 8.52 minimum pH value and good cleansing power) of silk fabric detergent was obtained. Therefore, increasing surfactants and decreasing caustic soda and vice versa adjusted the alkalinity of the detergent. And also increasing sodium silicate with sodium sulphate increases the cleansing power and foamability height of the produced detergent respectively. This paper work concludes that castor oil is good solvent for the production of synthetic detergent. However, as this paper use of only four ingredients is not enough for good quality of silk fabric detergents. Hence using other ingredients like optical brightness and enzymes was recommended for more good quality of synthetic detergents.
