The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Rassismus ohne Rassen bei Kant?
No full textDie Diskussionsreihe „Kant – Ein Rassist?“ widmet sich aus verschiedenen wissenschaftlichen Perspektiven der titelgebenden Frage. Die dritte von sechs Folgen erörtert die Frage, inwiefern in der Philosophie Immanuel Kants implizite rassistische Motive wirksam sind. Das Impulsreferat hält Marina Martinez Mateo, Professorin an der Akademie der bildenden Künste in München und Philosophin mit Schwerpunkt in der praktischen und politischen Philosophie sowie der Critical Race Theory. Die Repliken darauf halten Micha Brumlik, Antisemitismusforscher und Seniorprofessor an der Universität Frankfurt, und der Kant-Experte Marcus Willaschek, Vorsitzender der Kant-Kommission der Berlin-Brandenburgischen Akademie der Wissenschaften und Professor für Philosophie der Neuzeit an der Universität Frankfurt. In der anschließenden Diskussion knüpfen Federica Basaglia, Fabian Burt, Andre Hahmann, Daniel Kersting, Rocco Porcello, Maja Schepelmann und Volkmar Schocke an die Vorträge an und erweitern die Perspektive. Durch die Sitzung führt Dieter Schönecker. Der Impulsvortrag von Marina Martinez Mateo beginnt ab Minute 4:55. Die Replik von Micha Brumlik beginnt ab Minute 25:35. Die Replik von Marcus Willaschek beginnt ab Minute 38:40. Marina Martinez Mateo antwortet ab Minute 47:50 kurz auf die beiden Repliken. Die allgemeine Diskussion startet ab Minute 54:20

Dynamical Correlation Effects on Photoisomerization: Ab Initio Multiple Spawning Dynamics with MS-CASPT2 for a Model trans-Protonated Schiff Base
No full textWe investigate the photoisomerization of a model retinal protonated Schiff base (trans-PSB3) using ab initio multiple spawning (AIMS) based on multistate second order perturbation theory (MSPT2). Discrepancies between the photodynamical mechanism computed with three-root state-averaged complete active space self-consistent field (SA-3-CASSCF, which does not include dynamic electron correlation effects) and MSPT2 show that dynamic correlation is critical in this photoisomerization reaction. Furthermore, we show that the photodynamics of trans-PSB3 is not well-described by predictions based on minimum energy conical intersections (MECIs) or minimum energy conical intersection (CI) seam paths. Instead, most of the CIs involved in the photoisomerization are far from MECIs and minimum energy CI seam paths. Thus, both dynamical nuclear effects and dynamic electron correlation are critical to understanding the photochemical mechanism.AMOS program within the Chemical Sciences, Geosciences and Biosciences Division of the Office of Basic Energy Sciences, Office of Science, US Department of Energy; China Scholarship Council (CSC) [20110604097]SCI(E)[email protected]
Class-AB Amplifier with Third Order Nonlinearity Cancellation
No full textClass-AB amplifiers have better power efficiency than class-A amplifiers, which makes them a suitable choice for pipeline ADCs where low power, high performance opamps are desired. However, class-AB amplifiers have significantly lower linearity compared to class-A amplifiers due to the problem of cross-over distortion.
In this work, the problem of designing power efficient, high linearity class-AB amplifiers is addressed. The Monticelli bias scheme, which is the most popular class-AB bias scheme today, is analyzed. A new class-AB bias scheme, which is highly robust to process variations and achieves better linearity than the Monticelli bias scheme, is proposed. The problem of ���cross-over distortion��� in the class-AB amplifier is addressed and a solution is proposed. The idea behind this method is that the third order nonlinearity in the class-AB amplifier can be reduced or eliminated by matching the output stage NMOS and PMOS transistor transconductance across the input signal range, ensuring a constant transconductance at the output, improving linearity performance. To ensure good matching across process, voltage and temperature variations (P.V.T), a feedback calibration scheme is proposed
Ab initio pair potentials at metal-ceramic interfaces
No full textA systematic approach is proposed to obtain the interfacial interatomic potentials. By inverting ab initio adhesive energy curves for the metal-MgO ceramic interfaces, We derive interfacial potentials between Ag and O2-, Ag and Mg2+, Al and O2-, Al and Mg2+. The interfacial potentials, obtained from this method, demonstrate general features of bondings between metal atoms and ceramic ions
Symmetry matters: photodissociation dynamics of symmetrically versus asymmetrically substituted phenols
No full textWe report a combined experimental (H (Rydberg) atom photofragment translational spectroscopy) and theoretical (ab initio electronic structure and vibronic coupling calculations) study of the effects of symmetry on the photodissociation dynamics of phenols. Ultraviolet photoexcitation to the bound S-1((1)(pi pi)*) state of many phenols leads to some O-H bond fission by tunneling through the barrier under the conical intersection (CI) between the S-1 and dissociative S-2(1(pi sigma)*) potential energy surfaces in the RO-H stretch coordinate. Careful analysis of the total kinetic energy release spectra of the resulting products shows that the radicals formed following S-1 </p
Perceptions of pre- and post-event impacts of PEI 2014 year-long celebrations
No full textThis study examines Canadian perceptions of pre- and post-event impacts of the PEI 2014 Celebrations using the 2013 and 2015 surveys of PEI residents and other Canadians conducted by the Centre for Tourism Research. Overall, results indicate that Canadians’ awareness of, knowledge about, and attitudes toward the 1864 Charlottetown Conference and the PEI 2014 Celebrations increased and positively changed over time. The research also suggests that event organizers and/or destination tourism managers need to put greater emphasis on the “socio-cultural aspects” of the event such as community participation and cultural identity, and make an effort to increase tourism volume and value in order to obtain strong support from residents and be successful
Ultra-low-power, class-AB, CMOS four-quadrant current multiplier
No full textA class-AB four-quadrant current multiplier constituted by a class-AB current amplifier and a current splitter which can handle input signals in excess of ten times the bias current is presented. The proposed circuit operation is based on the exponential characteristic of BJTs or subthreshold MOSFETs. The multiplier is designed using the latter devices and achieves very low power consumption. Simulation results show that from a 0.65 V supply, the proposed circuit consumes 12.4 nW static power while less than 30 dB total harmonic distortion is achieved for an input modulation index up to 10.Microelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc
