Improved IIR Low-Pass Smoothers and Differentiators with Tunable Delay

Regression analysis using orthogonal polynomials in the time domain is used to derive closed-form expressions for causal and non-causal filters with an infinite impulse response (IIR) and a maximally-flat magnitude and delay response. The phase response of the resulting low-order smoothers and differentiators, with low-pass characteristics, may be tuned to yield the desired delay in the pass band or for zero gain at the Nyquist frequency. The filter response is improved when the shape of the exponential weighting function is modified and discrete associated Laguerre polynomials are used in the analysis. As an illustrative example, the derivative filters are used to generate an optical-flow field and to detect moving ground targets, in real video data collected from an airborne platform with an electro-optic sensor.Comment: To appear in Proc.

Future Property and the Torrens System

Since at least the seventeenth century, courts of equity have upheld the assignment of future property for valuable consideration. Despite this long lineage, however, there has been almost no scholarly analysis of how these principles might interact with the Torrens system. The present article addresses this deficiency. Generally, it argues that there are no reasons why principles of future property cannot be fully subsumed within the Torrens system

Freedom of religion and freedom of speech - The United States, Australia and Singapore compared

Freedom of Religion (more correctly, freedom of conscience, belief and religion under the International Covenant on Civil and Political Rights 1966 (ICCPR)), and Freedom of Speech have been logically tied together since human beings were sentient creatures. The two rights are inseparably connected by logic, since one cannot speak freely unless one has the freedom of conscience to think out something to say. For this reason, the two rights were combined in the First Amendment to the US Constitution in 1789 and that joinder has cemented the connection ever since even though the extrapolation of the two rights has seen them separated in modern human rights instruments. That latter-day separation in the interests of more complete expression however, seems to have disconnected the two rights in the minds of modern philosophers, legislators and judges

The 'Price' of Justice? Costs-Conditional Special Leave in the High Court

This article considers the High Court of Australia's occasional practice of granting special leave to appeal on a costs-conditional basis, whereby the appellant pays the respondent's costs regardless of the outcome. Despite the dissonance between this practice and traditional costs principles, there is little academic or judicial reflection on costs-conditional special leave. While several policy considerations support this practice, it is not unproblematic. What factors guide the exercise of this discretion? Why must an ultimately successful appellant fund the litigation? Should a party's financial status be a relevant consideration? If the Court is willing to depart from traditional costs rules here, why not elsewhere? This article uses quantitative and qualitative frameworks to consider such issues
