description: This study aims to analyze the determinants and patterns of the on-farm diversification among the agricultural producers in Algeria. The study uses a sample of agricultural pro-ducers randomly and proportionally selected from Northern Algeria and the data obtained was analyzed using three adequate regression models. Results indicate that, on the technical aspects, the farmers who have larger farm size, access to market information, more full land employment and an irrigation system, those who own machinery and livestock holdings are more likely to diversify, whereas those with off-farm income are likely to specialize. In order to promote crop diversification, providing farm machinery through easy loans and improv-ing access to market information and irrigation technologies should be given attention. Farmer’s experience and his age are the major socio-economic determinants of farm diversi-fication. The implication is drawn for provision of enabling socio-economic environment for the establishment of more diversification.
To go or not to go with the flow: Hawking radiation at strong coupling

description: We construct the gravitational dual of a one-parameter class of states of strongly coupled $SU(N)$ $\mathcal{N}=4$ SYM at infinite $N$ and asymptotic temperature $T_{\infty}$, on a fixed Schwarzschild black hole background with temperature $T_{\mathrm{BH}}$. The resulting bulk geometry is of the flowing type and allow us to measure Hawking radiation at strong coupling. The outgoing Hawking flux is a function of the dimensionless ratio $τ\equiv T_{\infty}/T_{\mathrm{BH}}$ and appears to be non-monotonic in $τ$. At present, we have no field theory understanding for this behaviour.

Data-driven kinematic and dynamic models for character animation
Creators: name: Yin, KangKang
Publisher: name: University of British Columbia
Year: 2011

description: Human motion plays a key role in the production of films, video games, virtual reality applications, and the control of humanoid robots. Unfortunately, it is hard to generate high quality human motion for character animation either manually or algorithmically. As a result, approaches based on motion capture data have become a central focus of character animation research in recent years. We observe three principal weaknesses in previous work using data-driven approaches for modelling human motion. First, basic balance behaviours and locomotion tasks are currently not well modelled. Second, the ability to produce high quality motion that is responsive to its environment is limited. Third, knowledge about human motor control is not well utilized. This thesis develops several techniques to generalize motion capture character animations to balance and respond. We focus on balance and locomotion tasks, with an emphasis on responding to disturbances, user interaction, and motor control integration. For this purpose, we investigate both kinematic and dynamic models. Kinematic models are intuitive and fast to construct, but have narrow generality, and thus require more data. A novel performance-driven animation interface to a motion database is developed, which allows a user to use foot pressure to control an avatar to balance in place, punch, kick, and step. We also present a virtual avatar that can respond to pushes, with the aid of a motion database of push responses. Consideration is given to dynamics using motion selection and adaption. Dynamic modelling using forward dynamics simulations requires solving difficult problems related to motor control, but permits wider generalization from given motion data. We first present a simple neuromuscular model that decomposes joint torques into feedforward and low-gain feedback components, and can deal with small perturbations that are assumed not to affect balance. To cope with large perturbations we develop explicit balance recovery strategies for a standing character that is pushed in any direction. Lastly, we present a simple continuous balance feedback mechanism that enables the control of a large variety of locomotion gaits for bipeds. Different locomotion tasks, including walking, running, and skipping, are constructed either manually or from motion capture examples. Feedforward torques can be learned from the feedback components, emulating a biological motor learning process that leads to more stable and natural motions with low gains. The results of this thesis demonstrate the potential of a new generation of more sophisticated kinematic and dynamic models of human motion.

An exact analytical expression for the spectral form factor of Poisson spectra can be obtained and is shown to agree well with numerical results on two models exhibiting many-body-localization: a disordered quantum spin chain and a phenomenological $l$-bit model based on the existence of local integrals of motion. We also identify a universal regime that is insensitive to the global density of states as well as spectral edge effects.

description: We report on transient effects in the microwave second-order response of different type of superconductors in the mixed state. The samples have contemporarily been exposed to a dc magnetic field, varying with a constant rate of 60 Oe/s, and a pulsed microwave magnetic field. The time evolution of the signal radiated at the second-harmonic frequency of the driving field has been measured for about 500 s from the instant in which the dc-field sweep has been stopped, with sampling time of about 0.3 s. We show that the second-harmonic signal exhibits two relaxation regimes; an initial exponential decay, which endures roughly 10 s, and a logarithmic decay in the time scale of minutes. Evidence is given that the decay in the time scale of minutes is ruled by magnetic relaxation over the surface barrier.

description: Agriculture continues to play an important role in the economy of most African countries. Thus, productivity growth in agriculture is necessary for economic growth and poverty reduction of the region. While, theoretically, investing in human capital improves productivity, the empirical evidence is somewhat mixed, especially in developing countries. In Ghana, maize is associated with household food security, and low-income households are considered food insecure if they have no maize in stock. But, due to low productivity, Ghanaian farmers are yet to produce enough to meet local demand. Using quantile and OLS regression techniques, this study contributes to the literature on human capital and productivity by assessing the effect of human capital (captured by education, farming experience and access to extension services) on maize productivity in Ghana. The results suggest that although human capital has no significant effect on maize yields, its effect on productivity varies across quantiles.
The star-forming environment of a ULX in NGC 4559: an optical study

description: We have studied the candidate optical counterparts and the stellar population in the star-forming complex around a bright ULX in NGC4559, using HST/WFPC2, XMM-Newton/OM, and ground-based data. We find that the ULX is located near a small group of OB stars. The brightest point source in the Chandra error circle is consistent with a single blue supergiant of mass ~ 20 M_sun and age ~ 10 Myr. A few other stars are resolved inside the error circle: mostly blue and red supergiants with masses ~ 10-15 M_sun and ages ~ 20 Myr. This is consistent with the interpretation of this ULX as a black hole (BH) accreting from a high-mass donor star in its supergiant phase, via Roche-lobe overflow. The observed optical colors and the blue-to-red supergiant ratio suggest a low metal abundance: 0.2 50 M_sun) than typical Milky Way BH candidates. The optical data favour a ``young'' BH originating in the recent episode of massive star formation; however, they also rule out an association with young massive star clusters. We speculate that other mechanisms may lead to the formation of relatively massive BHs (~ 50-100 M_sun) from stellar evolution processes in low-metallicity environments, or when star formation is triggered by galactic collisions.

description: Most binaries are undetected. Astrometric reductions of a system using the assumption that the object moves like a single point mass can be biased by unresolved binary stars. The discrepancy between the centre of mass of the system (which moves like a point mass) and the centre of light (which is what we observe) introduces additional motion. We explore the extent to which binary systems affect single object models fit to astrometric data. This tells us how observations are diluted by binaries and which systems cause the largest discrepancies - but also allows us to make inferences about the binarity of populations based on observed astrometric error. By examining a sample of mock observations, we show that binaries with periods close to one year can mimic parallax and thus bias distance measurements, whilst long period binaries can introduce significant apparent proper motion. Whilst these changes can soak up some of the error introduced by the binary, the total deviation from the best fitting model can be translated into a lower limit on the on-sky separation of the pair. Throughout we link these predictions to data from the Gaia satellite, whilst leaving the conclusions generalizable to other surveys.

description: This paper evaluates the contribution of agricultural growth to poverty reduction in the D.R.Congo over the projection period 2013 - 2020. It raises questions over the investment options to sustain such growth effort. We use a recursive dynamic computable general equilibrium model combine with survey-based micro simulation analysis at both national and subnational levels. We assume in the simulations that the additional growth in total factor productivity is an exogenous factor and find the following results. First, we find that 8.21 % agricultural annual growth rate is more effective at reducing poverty and achieves the goal of halving poverty by 2020. Second, we identify agricultural investment priorities and the required levels of public spending to achieve such growth and poverty reduction goals. We further analyze the growth at the subsector level and find that cereals and roots are more pro-poor. From this perspective, agricultural strategy based on expanding food crops production should be afforded the highest priority.

description: The collapse of a massive star with low angular momentum content is commonly argued to result in the formation of a black hole without an accompanying bright transient. Our goal in this Letter is to understand the flow in and around a newly-formed black hole, involving accretion and rotation, via general relativistic hydrodynamics simulations aimed at studying the conditions under which infalling material can accrete without forming a centrifugally supported structure and, as a result, generate no effective feedback. If the feedback from the black hole is, on the other hand, significant, the collapse would be halted and we suggest that the event is likely to be followed by a bright transient. We find that feedback is only efficient if the specific angular momentum of the infalling material at the innermost stable circular orbit exceeds that of geodesic circular flow at that radius by at least $\approx 20\%$. We use the results of our simulations to constrain the maximal stellar rotation rates of the disappearing massive progenitors PHL293B-LBV and N6946-BH1, and to provide an estimate of the overall rate of disappearing massive stars. We find that about a few percent of single O-type stars with measured rotational velocities are expected to spin below the critical value before collapse and are thus predicted to vanish without a trace.

description: Building Information Model visualization capability is an informative and essential feature of building performance simulation tools. Presenting the result of a performance simulation routine on a building while providing the end user with real time visual feedback on building-s geometrical properties, components and semantic information, prevents potential faults and inaccuracies in data input stage which may be caused by human error or malfunction of geometry import procedures. These errors will influence and falsify entire simulation processes and the optimization outcomes. This thesis project investigates and compares different aspects of current web-based visualization technologies, focusing on their implementation and adaptability. It then proposes a framework for mapping SBM, a recently developed building model of the SEMERGY project, to data format of the selected visualization technology, BIM Surfer. The SEMERGY project is a developing web-based tool aimed at comparative simulation and analysis of building design and retrofit options utilizing semantic web technologies. A serializer software solution is developed as the result of the investigations which can be implemented in the context of SEMERGY project.

description: The forest conservation policy instrument REDD+ (Reducing Emissions from Deforestation and Forest Degradation) is designed to compensate governments of tropical countries for their efforts to conserve forests. Food insecure countries that are specialized in agriculture and have weak institutions, are likely to face difficulties to enforce forest conservation. This article explores how far export tariffs on agricultural goods combined with public investments, could be used as a forest conservation policy mix in such contexts. We first show empirically that structural constraints to forest conservation policies are particularly pronounced in one third of countries where REDD+ programs are planned to be rolled out. We then develop a two sector competing land use model with a domestic food producing and an exporting agricultural sector. We show that it is possible to combine export tariffs with public investments such that deforestation decreases, while agricultural production levels and food prices remain constant.

description: The number density and flux of a meteoroid stream is enhanced near a massive body due to the phenomenon known as gravitational focusing. The greatest enhancement occurs directly opposite the massive body from the stream radiant: as an observer approaches this location, the degree of focusing is unbound for a perfectly collimated stream. However, real meteoroid streams exhibit some dispersion in radiant and speed that will act to eliminate this singularity. In this paper, we derive an analytic approximation for this smoothing that can be used in meteoroid environment models and is based on real measurements of meteor shower radiant dispersion.

Performance evaluation of ECMA-368 medium access control protocol for UWB ad-hoc networks
Creators: name: Arianpoo, Nasim
Publisher: name: University of British Columbia
Year: 2011

description: Ultra Wideband (UWB) is an emerging technology for high rate, short range wireless communications. Its unique features such as low power operation, robustness to multi-path fading, and accurate positioning capabilities makes UWB a good platform for wireless personal area networks (WPANs). One of the recent UWB standards standardized by the European Computer Manufacturers Association (ECMA) International is the ECMA- 368, which defines the physical (PHY) and media access control (MAC) layers for high rate WPANs. The MAC protocol in ECMA-368 has a superframe structure. Each superframe is divided into three different time periods. The beacon period is used for control purposes. The distributed reserved protocol (DRP) period allows devices to reserve bandwidth for data transmission. The PCA (prioritized contention access) period supports contention-based access between different traffic classes. In this thesis, we propose an analytical model to evaluate the performance of the ECMA-368 MAC protocol. We assume that packets follow the Markovian Arrival Process (MAP) and various service times can be modeled by different phase type distributions (PHYs). We apply the Matrix Geometric Method (MGM) technique and model the system as a MAP/PHY/1 queueing system. We derive the probability mass function (pmf) for the number of the packets in the queue, as well as the cumulative distribution function (CDF) for the waiting time of the packets in the queue. The correctness of our proposed analytical model is validated via simulations. We create the ECMA-368 module by using the OPNET simulator. Analytical and simulation results are presented under different scenarios

We demonstrate that the analysis of such data can be used to extract four basic parameters of such a transition and discuss the statistical requirements of the data acquisition. As advantages of the proposed scheme, a polymeric linker is explicitly included and thermal fluctuations within each well need not to be resolved.

description: The low level and adverse trends of youth employment in Africa and in the Middle East in the last decade are key driving factors of poverty, stress migration, frustration and political instability. There needs to be a sense of urgency to change the situation. How can employment, especially for youth, be created rapidly in these regions? The paper discusses different policies for the generation of mass employment of both skilled and unskilled labor. The sectoral priorities differ within the regions, with rural and agricultural jobs playing a more significant role in Sub-Saharan Africa (SSA). Both SSA and the Arab region show potentials for largescale public works programs. Un-orthodox economic policy actions are called for due to the pressing nature of the youth unemployment situation. These policies should aim at generating productive employment improving skills, and can be implemented both at the central and at the local level. Countries should be responsible for ownership, accountability and self-monitoring of policies and programs. Large scale international funding support should be considered when planning, implementation and supervision are actually credible and results oriented.

Two configurations have been considered: waves propagate from the convective layer to the radiative stratified stable layer, or the other way around. It has been found that waves prefer to survive at low latitudes when the stable layer is strongly stratified ($N^2/(2Ω)^2>1$). When the stable layer is weakly stratified ($N^2/(2Ω)^2<1$), however, waves can survive at any latitude if the meridional wavenumber is large. Then we have discussed transmission ratios for two buoyancy frequency structures: the uniform stratification, and the continuously varying stratification. For the uniform stratification, we have found that the transmission is efficient when the rotation is rapid, or when the wave is near the critical colatitude. For the continuously varying stratification, we have discussed the transmission ratio when the square of buoyancy frequency is an algebraic function $N^2\propto z^ν (ν>0)$. We have found that the transmission can be efficient when the rotation is rapid, or when the wave is near the critical colatitude, or when the thickness of the stratification layer is far greater than the horizontal wave length. The transmission ratio does not depend on the configurations (radiative layer sits above convective layer, or vice versa; wave propagates outward or inward), but only on characteristics of the wave (frequency and wavenumber) and the fluid (degree of stratification).

title: A World of Reading:An Intertextual Study of Janet Frame's Novels
Creators: name: Neville, Patricia Jean
Publisher: name: The Open University
Year: 2018

description: This thesis sheds new light on Janet Frame’s major novels by investigating her extensive and wide-ranging personal reading throughout her lifetime. It demonstrates how she weaves together her literary sources to create a web of intertextual relationships. Frame’s poetic language and literary allusions encourage many-layered readings and Mikhail Bakhtin’s analyses of novelistic prose illuminate my central research question concerning the relationship between Frame’s reading and her novels. I detail the literary context of early twentieth-century New Zealand, available reading material; attitudes towards literacy; and Frame’s schooling. I make an exhaustive study of under-examined material in the children’s page of Frame’s local newspaper; school, college and university reading; and her reading during her maturity. Frame considered poetry to be the highest of the literary arts, and I foreground the reading of poetry which chiefly informed Frame’s writing, including poetry which has so far not received attention, and show how her insertion of verse into her novels encourages a more investigative reading of her texts. I examine Frame’s use of the King James Bible, focussing on the less considered area of Frame’s use of the Bible’s poetry, before analysing her references to key Shakespeare plays. Finally I explore Frame’s allusion to folklore, European and Maori myth and oral literature. I examine the psychological insight of folk tale into childhood experience and its use in elucidating dark and uncommunicating elements of Frame’s characters. My investigation makes an original contribution to Frame studies by revealing that there are aspects of Frame’s literary hinterland and her intertextual use of it which merit more attention than they have received: poets and prose writers who have played a major but largely unrecognised contribution to her novels; and that Frame’s intertextuality is deeper, broader and more self-conscious than has so far been considered.

description: An overview of the random network model invented by Chalker and Coddington, and its generalizations, is provided. After a short introduction into the physics of the Integer Quantum Hall Effect, which historically has been the motivation for introducing the network model, the percolation model for electrons in spatial dimension 2 in a strong perpendicular magnetic field and a spatially correlated random potential is described. Based on this, the network model is established, using the concepts of percolating probability amplitude and tunneling. Its localization properties and its behavior at the critical point are discussed including a short survey on the statistics of energy levels and wave function amplitudes. Magneto-transport is reviewed with emphasis on some new results on conductance distributions. Generalizations are performed by establishing equivalent Hamiltonians. In particular, the significance of mappings to the Dirac model and the two dimensional Ising model are discussed. A description of renormalization group treatments is given. The classification of two dimensional random systems according to their symmetries is outlined. This provides access to the complete set of quantum phase transitions like the thermal Hall transition and the spin quantum Hall transition in two dimension. The supersymmetric effective field theory for the critical properties of network models is formulated. The network model is extended to higher dimensions including remarks on the chiral metal phase at the surface of a multi-layer quantum Hall system.

description: Topology optimization methods for inverse design of nano-photonic systems have recently become extremely popular and are presented in various forms and under various names. Approaches comprise gradient and non-gradient based algorithms combined with more or less systematic ways to improve convergence, discreteness of solutions and satisfaction of manufacturing constraints. We here provide a tutorial for the systematic and efficient design of nano-photonic structures by Topology Optimization (TopOpt). The implementation is based on the advanced and systematic approaches developed in TopOpt for structural optimization during the last three decades. The tutorial presents a step-by-step guide for deriving the continuous constrained optimization problem forming the foundation of the Topology Optimization method, using a cylindrical metalens design problem as an example. It demonstrates the effect and necessity of applying a number of auxiliary tools in the design process in order to ensure good numerical modelling practice and to achieve physically realisable designs. Application examples also include an optical demultiplexer.

description: Polarization observations of the cosmic microwave background with the Cosmic Background Imager from September 2002 to May 2004 provide a significant detection of the E-mode polarization and reveal an angular power spectrum of polarized emission showing peaks and valleys that are shifted in phase by half a cycle relative to those of the total intensity spectrum. This key agreement between the phase of the observed polarization spectrum and that predicted based on the total intensity spectrum provides support for the standard model of cosmology, in which dark matter and dark energy are the dominant constituents, the geometry is close to flat, and primordial density fluctuations are predominantly adiabatic with a matter power spectrum commensurate with inflationary cosmological models.

description: An on-farm cultivar evaluation trial for cucumber (Cucumis sativus L.) was conducted to compare differences in plant growth parameters related to fruit characteristics and marketable yield during the summer season. Eight cultivars (Calypso, Cobra, Eureka, Dasher Ii, SMR 58, Marketmore 76, Olympian Fl and Poinsett 76) were transplanted on June 12, 2003 into rows 1.52 m apart and spaced 0.41 m within rows. The trial was established using a randomized complete block design with three replications. Cultivars were harvested on five dates from July 23 to August 10, 2003. Data collected at each harvest included total number of fruits, fresh weight, number of marketable fruits, fruit length, vine length to first flower and fruit. Except for fruit length, differences among cultivars in all measured parameters were significant. New cultivars Cobra and Olympian Fi produced yields that were not significantly (P>0.05) different with common cultivars Calypso and Dasher 2. Cultivar Eureka produced the smallest (202 g) fruit while largest fruits (414 g) were produced by cultivar Olympian F|. Vine length to formation of first fruit was shortest (8.7 cm) with cultivar Olympian Fi and longest (20.9 cm) with cultivar Calypso. In all cultivars, formation of first flower in the vine did not develop into fruit. The study indicates that new and improved cultivars are available to farmers who want to replace old and common cultivars. Best cultivars are Cobra and Olympian F.

  Atlantic bonito, ρίϗι/παλαμίδα
 Atlantic bonito is a migratory schooling fish that reaches a maximum length of 85-91.4 cm, depending on location and a maximum weight of 5 kg. Its common length and weight are 50 cm and 2 kg. (Valeiras & Abad 2006a). Little is known about the physiology and behavior of this species. The best-studied area is the Black Sea and the Sea of Marmara. Atlantic bonito is also found in the Aegean. Bonitos migrate along the coasts over very large distances; tagged individuals have been located in the Black Sea and later in the Western Mediterranean.The issue of its spawning grounds in the area of Eastern Mediterranean is still uncertain. In the Mediterranean and the Aegean, the spawning season is from May to July (Valeiras & Abad 2006a). Bonitos from the Aegean Sea move through the Marmara into the Black Sea for reproduction in spring and back to the Aegean in autumn, from September onwards, but it appears that there are bonito schools that do not migrate to the Sea of Marmara or the Black Sea at all (Demir 1963; Yoshida 1980). For their migration routes within the Aegean some information is provided by Papanastasiou (1976: 502, 503), citingAnaniadis 1970: 298), though without distinguishing between Sarda sarda and Katsuwonus pelamis 3. Adult bonitos prey on schooling sardine, anchovy, mackerel, white bait and other small pelagic fishes.
 Bonitos are exploited by coastal fisheries, often artisanal. Their catches are locally very important in economic terms (e.g., Black Sea, Devedjian 1926: 16-23; Oray et al. 1997; Zengin et al. 2005) and they are systematically used for processing.

  Albacore, τόνος μαϗρόπτερος
Albacore is a large, cosmopolitan, migratory fish, reaching a maximum length of 140 cm and a maximum weight of 60.3 kg. A common length for mature individuals is 100 cm (Froese & Pauly 2019). It is not encountered in the Black Sea. Albacore tuna seldom come close to the shore and they prefer wide, open waters, where they spawn. Their migration routes are fairly uncertain. Their schools are not as large and dense as some other tuna and they are not often mixed with other species. For physiological reasons, young albacore are not able to move up and down the water column, so they tend to stay near the surface. That is why today they are more efficiently caught by surface gear, while the adults are caught at all depths (ICCAT 2006 -2016).
 In the Aegean, the fishing period for the albacore tuna is from mid-August to November, with the most important fishing area nowadays stretching between the Sporades and the Chalkidiki Peninsula. Less important areas are the Gulf of Patras, and the islands of Lesvos, Kalymnos, and Leros. Most of the fish caught are two to three years old and they are captured in their feeding area of concentration (De Metrio et al. 1989).

description: Many recent works have shown that adversarial examples that fool classifiers can be found by minimally perturbing a normal input. Recent theoretical results, starting with Gilmer et al. (2018b), show that if the inputs are drawn from a concentrated metric probability space, then adversarial examples with small perturbation are inevitable. A concentrated space has the property that any subset with Ω(1) (e.g., 1/100) measure, according to the imposed distribution, has small distance to almost all (e.g., 99/100) of the points in the space. It is not clear, however, whether these theoretical results apply to actual distributions such as images. This paper presents a method for empirically measuring and bounding the concentration of a concrete dataset which is proven to converge to the actual concentration. We use it to empirically estimate the intrinsic robustness to L-infinity and L2 perturbations of several image classification benchmarks. Code for our experiments is available at https://github.com/xiaozhanguva/Measure-Concentration.

description: Mit einer schriftlichen Befragung von hundert Lehrpersonen im Kanton Aargau wurde untersucht, welche Bedeutung mathematischem Lernen, insbesondere den Zählfertigkeiten, auf der Kindergartenstufe beigemessen wird. Ausgehend von der Hypothese, dass der Zeitpunkt des Ausbildungsabschlusses einen Einfluss auf die Einschätzung hat, wurde die Stichprobe in zwei Gruppen aufgeteilt. Die mittels T-Test ausgewerteten Daten zeigen zwar, dass Lehrpersonen mit Ausbildungsabschluss nach dem Jahr 2000 gewisse Fertigkeiten im numerischen Bereich, insbesondere das Zählen bis 20, im Schnitt wichtiger einstufen als Lehrpersonen mit Abschluss bis und mit dem Jahr 2000. Die Hypothese lässt sich jedoch nicht generell bestätigen. Aus der Reflexion wurden Folgerungen für die Arbeit der Schulischen Heilpädagoginnen und Heilpädagogen abgeleitet, welche mit fachdidaktischem Wissen Risikofaktoren bei Kindern erkennen und handeln können.
