description: In this paper, we present a low-power anomaly detection integrated circuit (ADIC) based on a one-class classifier (OCC) neural network. The ADIC achieves low-power operation through a combination of (a) careful choice of algorithm for online learning and (b) approximate computing techniques to lower average energy. In particular, online pseudoinverse update method (OPIUM) is used to train a randomized neural network for quick and resource efficient learning. An additional 42% energy saving can be achieved when a lighter version of OPIUM method is used for training with the same number of data samples lead to no significant compromise on the quality of inference. Instead of a single classifier with large number of neurons, an ensemble of K base learner approach is chosen to reduce learning memory by a factor of K. This also enables approximate computing by dynamically varying the neural network size based on anomaly detection. Fabricated in 65nm CMOS, the ADIC has K = 7 Base Learners (BL) with 32 neurons in each BL and dissipates 11.87pJ/OP and 3.35pJ/OP during learning and inference respectively at Vdd = 0.75V when all 7 BLs are enabled. Further, evaluated on the NASA bearing dataset, approximately 80% of the chip can be shut down for 99% of the lifetime leading to an energy efficiency of 0.48pJ/OP, an 18.5 times reduction over full-precision computing running at Vdd = 1.2V throughout the lifetime.

description: Both WTO and the EU use a “Rule of additional costs” (RAC) to restrict payments for ecological services in agriculture in order to prevent trade distortions. We assess this rule in the light of modern economic theory. It is shown that the RAC is efficient, if conventional agriculture is competitive without other payments. In regions where agriculture is not competitive though and is said to be important for ecological purposes the payments for ecological services must exceed additional costs. In these cases three criteria exist to prevent trade distortions as far as possible: the regions in which farmers are eligible to more than additional costs must be clearly defined by economic and ecological indicators, payments must not exceed the costs for equivalent nature conservation measures by non-farmers and the ecological benefit of the farmer’s actions must be demonstrated. The definition of the regions where more than additional costs can be paid should be made at the EU-level if the ecological importance of these regions is of international concern.
Nonlinear supratransmission and bistability in the Fermi-Pasta-Ulam model

description: The recently discovered phenomenon of nonlinear supratransmission consists in a sudden increase of the amplitude of a transmitted wave triggered by the excitation of nonlinear localized modes of the medium. We examine this process for the Fermi-Pasta-Ulam chain, sinusoidally driven at one edge and damped at the other. The supratransmission regime occurs for driving frequencies above the upper band-edge and originates from direct moving discrete breather creation. We derive approximate analytical estimates of the supratransmission threshold, which are in excellent agreement with numerics. When analysing the long-time behavior, we discover that, below the supratransmission threshold, a conducting stationary state coexists with the insulating one. We explain the bistable nature of the energy flux in terms of the excitation of quasi-harmonic extended waves. This leads to the analytical calculation of a lower-transmission threshold which is also in reasonable agreement with numerical experiments.

Reasonable impartiality : toward a foundation for moral education
Creators: name: Priestman, Scott
Publisher: name: University of British Columbia
Year: 2009

description: This thesis develops a conceptual framework for one aspect of moral education, moral reasoning. It begins with the assumption that any adequate program of moral education must equip students with the abilities (broadly defined to include skills, dispositions, attitudes and intellectual capacities) that will enable them to reason through the kinds of moral problems they will encounter in their lives. Following the work of many ethicists and moral educators, I look to practical reasoning as the basis of such an education. This thesis also builds on previous work that undertakes to establish defensible standards of good moral thinking. Working within a Popperian framework, I propose impartiality as the test to evaluate the adequacy of our moral judgements and actions. As I conceptualize it, impartiality is met if no one can reasonably object to my moral judgement or action. Accordingly, the thesis outlines a number of tests to determine if an objection is reasonable or not. By comparing my conception of impartiality to other common ones (as developed by Kant, Mill , Rawls, Hare and Habermas) and defending it against critics of impartiality (like Iris Marion Young) I articulate a common ground that retains something that is fundamental to the concept yet avoids the problems that many see with it. I conclude by suggesting how a pedagogy of critical engagement with these standards (both how they are generated and how they are applied) will help foster moral growth.

description: The article addresses the role the European Union plays in the agri-environmental policy and considers the co-financing of agri-environmental programmes in Germany. First, the development of measures taken under this policy is described from the 1980ies until the present Agenda 2000, taking especially into account the effects of financial promotion by the EU. In addition, a view on nature conservation and water protection reveals the sometimes conflicting interactions between agri-environmental measures and other areas and instruments of environmental policy. In a second part, three sections describe identified problems resulting from the influence of the EU: the effects on the choice and design of agri-environmental policy instruments in the Federal States of Germany, the uncertainties and contradictions resulting in the area of property rights, and the controversially rated income effects. The results are brought together and discussed with reference to the current debate on the disentanglement of agri-environmental policy. Finally, conclusions are drawn for the practical design of agri-environmental policy.

description: Blazars are relativistic magnetized plasma outflows from supermassive black holes that point very close to our line of sight. Their emission is nonthermal dominated and highly variable across the entire electromagnetic spectrum. Relativistic magnetic reconnection has been proposed as the driver of particle acceleration during blazar flares. While recent particle-in-cell simulations have self-consistently studied the evolution of magnetic reconnection and particle acceleration therein, the resulting radiation signatures have not been systematically explored. In particular, the polarization signatures, which directly reflect the characteristic strongly dynamical magnetic field evolution during reconnection, have not been carefully investigated. In this paper, we present a systematic study of radiation and polarization signatures arising from magnetic reconnection in blazars, based on combined PIC and polarized radiation transfer simulations with various physical parameters. We identify a harder-when-brighter trend in the spectral evolution. Moreover, higher-frequency bands tend to flare earlier than lower-frequency bands in the synchrotron spectral component. Most importantly, polarization signatures appear more variable with higher frequencies. We find that the temporal polarization variations strongly depends on the guide field strength. Specifically, reconnection with significant guide field component leads to very high polarization degree that contradict to typical blazar observations, while large polarization angle rotations are unique signatures of magnetic reconnection between nearly anti-parallel magnetic field lines. These rotations are at least $90^o$ and can extend to $>180^o$, and they may rotate in both directions. These results imply that blazars that have shown large polarization angle rotations intrinsically have more nearly anti-parallel magnetic field morphology.

description: The Theory of Fiscal Federalism offers a normative framework to evaluate the existing allocation of competences. To derive an actual relevant scope for reforms supporting an efficient Agri-environmental Policy the general theoretical criteria have to be specified. Thus, the parameters defining theoretically the optimal degree of centralisation will be applied to sectoral characteristics. Additional agri-environmental sub-competencies will be differentiated to identify deficits regarding the Principle of Equivalence. Based on this existing infringements with respect to agri-environmental measures are noticeable what requires a changed allocation of competences.

description: We consider families of Hamiltonian systems in two degrees of freedom with an equilibrium in 1:2 resonance. Under detuning, this "Fermi resonance" typically leads to normal modes losing their stability through period-doubling bifurcations. For cubic potentials this concerns the short axial orbits and in galactic dynamics the resulting stable periodic orbits are called "banana" orbits. Galactic potentials are symmetric with respect to the co-ordinate planes whence the potential -- and the normal form -- both have no cubic terms. This $\mathbb{Z}_2 \times \mathbb{Z}_2$-symmetry turns the 1:2 resonance into a higher order resonance and one therefore also speaks of the 2:4 resonance. In this paper we study the 2:4 resonance in its own right, not restricted to natural Hamiltonian systems where $H = T + V$ would consist of kinetic and (positional) potential energy. The short axial orbit then turns out to be dynamically stable everywhere except at a simultaneous bifurcation of banana and "anti-banana" orbits, while it is now the long axial orbit that loses and regains stability through two successive period-doubling bifurcations.

description: We present results of near infrared imaging of the disk-galaxy-merger NGC 6240 using adaptive optics on the Keck II Telescope and reprocessed archival data from NICMOS on the Hubble Space Telescope. Both the North and South nuclei of NGC 6240 are clearly elongated, with considerable sub-structure within each nucleus. In K' band there are at least two point-sources within the North nucleus; we tentatively identify the south-western point-source within the North nucleus as the position of one of the two AGNs. Within the South nucleus, the northern sub-nucleus is more highly reddened. Based upon the nuclear separation measured at 5 GHz, we suggest that the AGN in the South nucleus is still enshrouded in dust at K' band, and is located slightly to the north of the brightest point in K' band. Within the South nucleus there is strong H2 1-0 S(1) line emission from the northern sub-nucleus, contrary to the conclusions of previous seeing-limited observations. Narrowband H2 emission-line images show that a streamer or ribbon of excited molecular hydrogen connects the North and South nuclei. We suggest that this linear feature corresponds to a bridge of gas connecting the two nuclei, as seen in computer simulations of mergers. Many point-like regions are seen around the two nuclei. These are most prominent at 1.1 microns with NICMOS, and in K'-band with Keck adaptive optics. We suggest that these point-sources represent young star clusters formed in the course of the merger.

description: The following analysis leads to an empirically based ranking, which embodies political decision makers to evaluate the necessity of horizontal co-ordination for different issues concerning nature and landscape conservation. First of all the relevant German law and order as well as its spatial conservation categories will be explained (Chapter 2). Secondly the conclusions concerning the spatial inhomogeneity of conservation areas and their implications to environmental-policy are substantiated by the principles of the economic theory of environmental federalism (Chapter 3). Thirdly the definition of suitable concentration indices follows, their quantification for examples of conservation categories (Chapter 4), and the draw up of political recommendations, which are based on these results (Chapter 5).

description: We present a method for density-functional modeling of metallic overlayers grown on metallic supports. It offers a tool to study nanostructures and combines the power of self-consistent pseudopotential calculations with the simplicity of a one-dimensional approach. The model is applied to Pb layers grown on the Cu(111) surface. More specifically, Pb is modeled as stabilized jellium and the Cu(111) substrate is represented by a one-dimensional pseudopotential that reproduces experimental positions of both the Cu Fermi level and the energy gap of the band structure projected along the (111) direction. The model is used to study the quantum well states in the Pb overlayer. Their analysis gives the strength of the electron confinement barriers at the interface and at the surface facing the vacuum. Our results and analysis support the interpretation of the quantum well state spectra measured by the scanning tunneling spectroscopy.

description: After describing a series of plans with implications for land use, this study aims to examine the collaboration problems which exist between the main groups involved and elaborate on potential legal solutions. Main results are the following: 1. German law requires that the interests of the farming community and nature conservation are taken into account in the overall consideration of planning decisions. Any specialist plans already available – bearing in mind the different procedures existing between the various federal states – must also be integrated into the planning process. 2. If farming interests or the interests of nature conservation and countryside protection cannot be asserted in the overall planning process as laid down by the law, the decisions are in many cases political and, as such, cannot be dealt with by legal means. In legal terms, the interests are already recognised as having equal status. 3. The rivalry frequently encountered between the farming community and nature conservation over the use of land mostly occurs when the land is intended to be used for other purposes (i.e. for housing development, infrastructure etc.). The necessity for conservation-related compensation creates a relationship of tension which in many cases is not directly attributable to nature conservation and farming. An example is the low amount of conservation-related compensation when viewed in comparison with a housing development project. 4. The law only partially regulates the coordination of nature-preservation and agrarian specialist planning. However, both sides – the farming community (consideration of high-yielding land) and conservation (upgrading the chances of realising landscape planning) have an equal interest in seeing coordinated measures implemented at an early stage. In practice, an adequate procedure has already been developed. In legal terms, however, it is difficult to register and cope with the possibilities and problems associated with the informal methods of coordination. 5. Ultimately, the success of the coordination and collaboration depends largely on the commitment shown by the parties involved. However, the coordination of regional planning instruments at an early stage does not solve the problems of acceptance between the farming community and nature conservation as long as the realisation of legal conservationist measures are financially unattractive for farmers or could even jeopardise their existence.
Dimension dependence of numerical simulations on gravitational waves from protoneutron stars

Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We examine the eigenfrequencies of gravitational waves from the protoneutron stars (PNSs) provided via the core-collapse supernovae, focusing on how the frequencies depend on the dimension of numerical simulations especially for the early phase after core bounce. As expected, we find that the time evolution of gravitational wave frequencies depends strongly on the dimension of numerical simulation as well as the equation of state for high density matter. Even so, we find that the fundamental frequency as a function of PNS average density and the ratio of the specific eigenfrequencies to the fundamental frequency as a function of PNS properties are independent of the dimension of the numerical simulations, where the dependence of the equation of state is also very weak in this early postbounce phase. Thus, one can safely discuss the gravitational wave frequencies of the PNSs as a function of the PNS average density or compactness even with the frequencies obtained from the one dimensional simulations. We also provide phenomenological relation between the compactness and average density as well as the relation among the $f$-, $p$-, and $g$- mode frequencies.
Bodies, memories, and empire : life stories about growing up in Jamaica 1943-1965
Creators: name: Brown, Yvonne Salome
Publisher: name: University of British Columbia
Year: 2009

description: "What's a mother?" is the first and most significant question I remember asking as a child. It led to another: "Who is my mother?" Particular events, people, and landscapes of my past in Jamaica beckoned me to return to the land of my birth to search for the answers to these two questions. Once begun, the investigation raised more questions: Without a mother to give me a sense of self, then 'Who am I?' - 'Who have I become?' - 'What forces have shaped my character and my outlook on life?'. I use my body as a living archive from which to retrieve fragmentary details from inestimable amounts of data, stored in the conscious and the unconscious. I construct life stories that blend fictional and non-fictional elements. Conversations with Caribbean friends and acquaintances both prompt my memory and elaborate details. Caribbean fiction writers provide models for representing the human condition of Caribbean peoples. Diaries of slavers and plantation owners, primary documents obtained from the National Archives of Jamaica, and the libraries of the University of the West Indies provide further data. I include observations and informed accounts of my travels along the colonial trails. These life stories are about my motherlust, my family, my church, my schooling and political moments in the history of the island we call Jamaica. History and politics explain the social phenomena that emerge. In composing these narratives, I speak in three embodied voices: the subject, researcher, and author. I bring in the voices of significant family members, teachers, preachers, friends and the folk in the Jamaican patois. These stories attest to the truth-value of genetic, autobiographical, topographical, and archival memory as matrices within which to conduct narrative inquiry into one's origin. Embedded within these stories are lessons about identity formation, curricular policy, schooling and the content of a colonial education, the subjugation of the history of African people in New World slavery, and critiques of multiculturalism and globalization. It is my aim that in reading these stories, students, teachers, educational and community leaders will appreciate the generative potential of repressed memories.

description: Decreasing thermal conductivity of a thermoelectric material is always a prerequisite for its potential application. Using first-principle calculations, we examine the magnetism induced change in lattice thermal transport in bismuth telluride. The source of magnetic moment, Cr in the doped system, weakly magnetizes the coordinated Te atoms to make the latter's phonon softer than that in the pure compound. Though the transition metal dopants do not participate directly in the heat conduction process, the anharmonicity induced by them favor in reducing the lattice thermal conductivity. Large anharmonicity in $(Bi_{0.67}Cr_{0.33})_2Te_3$ reduces the in-plane room temperature lattice thermal conductivity by $\sim 79\%$. The thermal conductivity, strictly, does not vary monotonically with doping concentration. Even, for any particular doping level, the thermal conductivity is different for different configurations which is related to the internal energy of the system. We found that the internal energy variance of 0.03 $eV$ would reduce the in-plane thermal conductivity of the room temperature lattice by at least 60$\%$ for 50$\%$ doping.

description: This paper investigates whether deregulation of the Australian wheat export market induced a structural change in the price data generation process. We examine the unit root properties of Western Australian wheat prices by testing for the possibility of single and double structural breaks in the price series. Daily prices for the period 20th of May 2003 to 14th of September 2010 are used. We find that the wheat price series has a unit root with two structural breaks but neither break coincided with the time when the Wheat Export Marketing Act 2008 came into effect on 1 July 2008. We conclude that change in local market behaviour would have started prior to actual deregulation with subsequent effect on local price.

description: The photoluminescence spectra of band-edge transitions in GaN is studied as a function of temperature. The parameters that describe the temperature dependence red-shift of the band-edge transition energy and the broadening of emission line are evaluated using different models. We find that the semi-empirical relation based on phonon-dispersion related spectral function leads to excellent fit to the experimental data. The exciton-phonon coupling constants are determined from the analysis of linewidth broadening.

description: The theoretical framework developed by the Transaction Costs Economics has been used by several authors to improve the production system different actors’ relationships comprehension. However, Transaction Costs Theory application in agri-industrial Systems have been infrequently treated in scientific literature, especially in unstructured and incipient systems, such as beekeeping in the city of Campo Grande, in Mato Grosso do Sul - Brazil. In this way, this paper shows an analysis of conventions importance in transaction costs reduction at Honey Agri-industrial System in Campo Grande. To this finality, case studies were conducted using secondary and primary data (collected through interviews with production chain operators). Their results lead to the conclusion that, for this Agri-industrial System, convention theory is a useful approach to explanation of the production system governance mechanisms, characterized by market informal guarantees, structured on trust and reputation. Furthermore, the study showed that Convention Economic Theory complements the Transaction Costs Economics Theory, because it adds a new element to be considered in Agriindustrial Systems Transaction Costs Analyzes.

description: This paper discusses land occupation and natural resources utilization, and analyses the forest conservation paradox (desire/barriers) experienced by small farmers of Alto Moju region, in the Amazon. This paradox is marked by a lack of land tenure regularization, the role of timber as a tradable asset saved for hard times, and low level of organization amongst local families. To proceed with the analysis, the authors used qualitative research methods (semi-directive interviews and participant observation), which favored the farmers’ representations regarding the use of natural resources and the social reproduction of families. From examining the land occupation history and the zoning with key actors, the authors conclude that the social reproduction of families in the Alto Moju is at risk, primarily caused by pressure for timber, lack of basic social services and of legal land access. Community Forest Management is seen as a good alternative to conservation and income generation for local communities. However, its implementation is hindered by barriers which are discussed in this paper.

description: We introduce a machine learning method in which energy solutions from the Schrodinger equation are predicted using symmetry adapted atomic orbitals features and a graph neural-network architecture. \textsc{OrbNet} is shown to outperform existing methods in terms of learning efficiency and transferability for the prediction of density functional theory results while employing low-cost features that are obtained from semi-empirical electronic structure calculations. For applications to datasets of drug-like molecules, including QM7b-T, QM9, GDB-13-T, DrugBank, and the conformer benchmark dataset of Folmsbee and Hutchison, \textsc{OrbNet} predicts energies within chemical accuracy of DFT at a computational cost that is thousand-fold or more reduced.

description: The Drell-Hearn-Gerasimov sum rule for the deuteron is studied in nuclear effective field theory. The low-energy theorem for the spin-dependent Compton amplitude $f_1(ω)$ is derived to the next-to-leading order in low-energy expansion. The spin-dependent photodisintegration cross section $σ^P-σ^A$ is calculated to the same order, and its contribution to the dispersive integral is evaluated.

description: We investigate hydrodynamic instability of accelerating ionization fronts using two dimensional hydrodynamic simulations that include detailed energy deposition and release due to the absorption of UV radiation, recombination of hydrogen, radiative molecular cooling, and magnetic pressure. We consider linear perturbation growth and find that the stabilization mechanism associated with non-accelerated fronts remains a significant factor even when acceleration is present. Conversely, if recombination in the ionized region is turned off,Rayleigh-Taylor (RT) instability becomes effective, and the classical RT growth rate recovered.

Branching ratio of Type Ib/c supernovae into GRB-supernovae

description: We study centered and decentered nucleation of black holes in core-collapse of massive stars in binaries. By Bekenstein's gravitational-radiation recoil mechanism, a newly nucleated black hole typically leaves the central core prematurely. With low probability, the black hole remains centered and matures to a high-mass black hole which spins rapidly if the binary is compact. GRB030329/SN2003dh demonstrates that Type Ib/c supernovae are the parent population of long GRBs, whose branching ratio is ${\cal R}=(2-4)\times 10^{-3}$. We identify ${\cal R}$ with the low probability of centered nucleation in compact binaries. Decentered events are predicted to produce a single short burst in gravitational radiation. Centered events are predicted to produce a second, long-burst in gravitational radiation powered by a luminous black hole. These signatures are of interest to LIGO, VIRGO and TAMA.

Improved channel state dependent scheduling for WLANs
Creators: name: Zhang, Limei
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on the study of Channel State Dependent Scheduling (CSDS) based scheduling schemes for Wireless Local Area Networks (WLAN). CSDS based scheduling schemes can improve the usage efficiency of scarce radio resource since packets transmitted on wireless channels are often subject to burst errors which cause back-to-back packet losses. By taking into account the channel state in scheduling decisions, CSDS based schemes can achieve a large improvement in total throughput compared to FIFO scheme, which is currently used in WLAN systems. However, if not properly designed, a CSDS scheme can cause unfair resource allocation among users. Various mechanisms have been proposed for addressing the fairness problem in the literature, but unfortunately most of them are too complicated to be employed in WLAN . The main contribution of this thesis is to propose a simple compensation mechanism which is easy to implement. Based on the compensation mechanism, three CSDS based scheduling schemes are designed for WLAN. Among them, Max S* selects the best channel state S*, which is calculated according to the compensation mechanism; IWRR (Improved Weighted Round Robin) adopts dynamically changing weights for users. The weight is derived based on the compensation mechanism. A hybrid scheme, IWRR+Max S*, is proposed which possesses the advantages of both of IWRR and Max S*. A WLAN system simulation is used to show that the proposed schemes can yield substantial improvements in short-term fairness compared to CSDS+RR (Round Robin) in most test scenarios, while still maintaining high channel efficiency.

description: Nearly 150 years ago, Lord Kelvin proposed the isotropic helicoid, a particle with isotropic yet chiral interactions with a fluid, so that translation couples to rotation. An implementation of his design fabricated with a three-dimensional printer is found experimentally to have no detectable translation-rotation coupling, although the particle point-group symmetry allows this coupling. We explain these results by demonstrating that in Stokes flow, the chiral coupling of such isotropic helicoids made out of non-chiral vanes is due only to hydrodynamic interactions between these vanes. Therefore it is small. In summary, Kelvin's predicted isotropic helicoid exists, but only as a weak breaking of a symmetry of non-interacting vanes in Stokes flow.

description: The agroforest systems - SAFs - allow the balance between production and biodiversity conservation. The objective of this paper is to measure the results and impacts of SAFs in Alto Jequitinhonha, in the Northeastern region of Minas Gerais, investigating features related to the household organization and management and conservation of natural resources. The research work was performed in 18 rural communities of five towns by means of interviews with 33 household farmers, named “monitors”, belonging to the acting base of the Centro de Agricultura Alternativa Vicente Nica (Vicente Nica Alternative Agriculture Center) – CAV – a non-governmental organization which acts in programs of rural development in the region. It was realized that SAFs have contributed to the improvement of the productive conditions, to the qualification of farmers and conservation of natural resources. It was verified that there are technical, financial and organizational limitations for the expansion of the proposal. It follows that SAFs, in Alto Jequitinhonha, constitutes an agroecological innovation feasible to the household farming of that region, and the actions developed by CAV deserve further attention, from the governmental scenery to the rural millieu.
