Coupling of energy from quantum emitters to the plasmonic mode of V groove waveguides: A numerical study

This work is a theoretical investigation into the coupling of a single excited quantum emitter to the plasmon mode of a V groove waveguide. The V groove waveguide consists of a triangular channel milled in gold and the emitter is modeled as a dipole emitter, and could represent a quantum dot, nitrogen vacancy in diamond, or similar. In this work the dependence of coupling efficiency of emitter to plasmon mode is determined for various geometrical parameters of the emitter-waveguide system. Using the finite element method, the effect on coupling efficiency of the emitter position and orientation, groove angle, groove depth, and tip radius, is studied in detail. We demonstrate that all parameters, with the exception of groove depth, have a significant impact on the attainable coupling efficiency. Understanding the effect of various geometrical parameters on the coupling between emitters and the plasmonic mode of the waveguide is essential for the design and optimization of quantum dot–V groove devices.

Adaption and use of a compressible flow code for turbomachinery design

The present paper presents and discusses the use of dierent codes regarding the numerical simulation of a radial-in ow turbine. A radial-in ow turbine test case was selected from published literature [1] and commercial codes (Fluent and CFX) were used to perform the steady-state numerical simulations. An in-house compressible- ow simulation code, Eilmer3 [2] was also adapted in order to make it suitable to perform turbomachinery simulations and preliminary results are presented and discussed. The code itself as well as its adaptation, comprising the addition of terms for the rotating frame of reference, programmable boundary conditions for periodic boundaries and a mixing plane interface between the rotating and non-rotating blocks are also discussed. Several cases with dierent orders of complexity in terms of geometry were considered and the results were compared across the dierent codes. The agreement between these results and published data is also discussed.

Cattanach v Melchior : babies, blessings and burdens

This article considers the High Court decision of Cattanach v Melchior, which permitted the recovery of damages for the cost of raising a child born through medical negligence. It discusses the reasoning in each of the judgments and seeks to identify themes so as to explain the divide between the majority and minority. It also considers the impact of legislative intervention in Queensland and New South Wales.

e-Technology v t-Engagement : a snapshot of Australia's digital economy readiness

Before e-Technology’s effects on users can be accurately measured, those users must be fully engaged with the relevant systems and services. That is they must be able to function as part of the digital economy. The paper refers to this ‘user functionality’ as t-Engagement. Not all users are t-Engaged and in many instances achieving t-Engagement will require assistance from external sources. This paper identifies the current state of Australia’s regional digital economy readiness and highlights the role of Local Government Authorities (‘LGAs’) in enabling t-Engagement. The paper analyses responses to the 2012 BTA, NBN and Digital Economy Survey by LGA and other regional organizations within Australia. The paper’s particular focus is on the level of use by Local Government Authorities of federal, state and other programs designed to enable t-Engagement. The analysis confirms the role of LGAs in enabling t-Engagement and in promoting Australia’s digital economy. The paper concludes by reinforcing the need to ensure ongoing meaningful federal and State support of regional initiatives, as well as identifying issues requiring specific attention.

The molecular structure of the phosphate mineral chalcosiderite – a vibrational spectroscopic study

The mineral chalcosiderite with formula CuFe6(PO4)4(OH)8⋅4H2O has been studied by Raman spectroscopy and by infrared spectroscopy. A comparison of the chalcosiderite spectra is made with the spectra of turquoise. The spectra of the mineral samples are very similar in the 1200–900 cm−1 region but strong differences are observed in the 900–100 cm−1 region. The effect of substitution of Fe for Al in chalcosiderite shifts the bands to lower wave numbers. Factor group analysis (FGA) implies four OH stretching vibrations for both the water and hydroxyl units. Two bands ascribed to water are observed at 3276 and 3072 cm−1. Three hydroxyl stretching vibrations are observed. Calculations using a Libowitzky type formula show that the hydrogen bond distances of the water molecules are 2.745 and 2.812 Å which are considerably shorter than the values for the hydroxyl units 2.896, 2.917 and 2.978 Å. Two phosphate stretching vibrations at 1042 and 1062 cm−1 in line with the two independent phosphate units in the structure of chalcosiderite. Three bands are observed at 1102, 1159 and 1194 cm−1 assigned to the phosphate antisymmetric stretching vibrations. FGA predicts six bands but only three are observed due to accidental degeneracy. Both the ν2 and ν4 bending regions are complex. Four Raman bands observed at 536, 580, 598 and 636 cm−1 are assigned to the ν4 bending modes. Raman bands at 415, 420, 475 and 484 cm−1are assigned to the phosphate ν2 bending modes. Vibrational spectroscopy enables aspects of the molecular structure of chalcosiderite to be assessed.

Tax and equality in 1972: The case of Lodge v FCT

This paper is part of a larger project described at http://www.law.uq.edu.au/australian-feminist-judgments-project as follows: This project draws its inspiration from two significant recent developments in law and feminist scholarship. The first has been the emergence in Canada and the UK of feminist judgment-writing projects, in which feminist academics, lawyers and activists have written alternative judgments in a series of legal cases, imagining the different decision that might have been made by a feminist judge hearing the case. The second has been the incremental shift in recent years in the number of women judges and Magistrates presiding in courts and tribunals throughout Australia. As part of this project, a group of scholars will write alternative feminist judgments. This paper is one of the alternative feminist judgements. The case used for this discussion is Lodge v Federal Commissioner of Tax [1972] HCA 49. In that case, a woman, earning income by way of commission in her occupation as a law costs clerk, which she carried out at her home, claimed to deduct from her assessable income child care fees that enabled her to devote time and attention to her work. The High Court held that no right to a deduction had arisen. It found that, although the purpose of the expenditure was for gaining assessable income, it did not take place in, or in the course of, preparing bills of cost. Further, the expenditure was of a ‘private or domestic’ nature. This seminal taxation decision, which prevents deductions for childcare, has broad financial ramifications for workers in the home and those with childcare responsibilities. It designates childcare duties as ‘private’, notwithstanding the need for these in order, particularly for women, to work in the public sphere.

Calligraphy and causation : two obstetric management cases - Hirst v Sydney South West Area Health and King v Western Sydney local health network

Two recent decisions of the Supreme Court of New South Wales in the context of obstetric management have highlighted firstly, the importance of keeping legible, accurate and detailed medical records; and secondly, the challenges faced by those seeking to establish causation, particularly where epidemiological evidence is relied upon...

Open for Inspection? Julstar Pty Ltd v Lynch Morgan Lawyers [2012] QDC 272

In Julstar Pty Ltd v Lynch Morgan Lawyers [2012] QDC 272 Dorney QC DCJ considered whether an applicant for an assessment of all or part of their costs under s 335 of the Legal Profession Act 2007 (Qld) (LPA) must provide grounds on which they dispute the amount of the costs charged or their liability to pay them. His Honour also made an order for inspection of the solicitor’s file, despite a claimed lien for unpaid fees.
