description: The decline in the smuggling of people from Indonesia to Australia since late 2013 is primarily attributable to unilateral deterrence policies under Australia’s Operation Sovereign Borders, rather than to bilateral or multilateral cooperation in enforcing anti-people smuggling laws in the region. Yet, more than 30 asylum-seeker boats have departed from Indonesia since that time. Australia’s handling of one boat in particular stands out, not least because of the intense media attention it attracted. In May 2015, Australian authorities intercepted an Indonesian boat carrying 65 asylum seekers and allegedly paid the six smugglers on board to return the asylum seekers to Indonesia. In this article, we reconstruct what happened at sea, and put forward a number of arguments that categorize this “turnback” as a form of state-sanctioned people smuggling. Our article also raises a number of further questions about looming risks if state-sanctioned people smuggling was to be employed more widely by states in other areas of the world where people cross the sea to seek asylum. Not only would the practice severely undermine international collaborations that have developed to combat people smuggling, but it would also create additional safety risks for those who are turned back.

description: The dispute between the US and EU over GM foods at the WTO is examined in terms of the issues it raises about protectionism and environmental protection and precaution. The issue of whether GM, GM Derived and Non-GM foods are equivalent to each other is examined using data from a national choice modelling study in the UK. These categories of food are critical since they underpin the EU's new food labelling regime which it hoped would defuse the WTO dispute. The results are analysed using a Bayesian mixed logit model which allows greater flexibility in the modelling of preference distributions. This is particularly crucial where, as in this case, bi-modal distributions are identified with some indifferent or mildly averse to GM foodtypes while others are strongly averse. A strong finding of the analysis is that people treat ingredients derived from GM crops (but free from altered DNA) as equivalent to GM ingredients. This supports a labelling regime based on process rather than simply product and suggests considerable consumer benefits from the EU's new GM labelling regime.

description: We study adsorption at periodically corrugated substrates formed by scoring rectangular grooves into a planar solid wall which interacts with the fluid via long-range (dispersion) forces. The grooves are assumed to be macroscopically long but their depth, width and separations can all be molecularly small. We show that the entire adsorption process can be divided into three parts consisting of (i) \emph{filling} the grooves by a capillary liquid; (ii) \emph{depinning} of the liquid-gas interface from the wall edges; and (iii) \emph{unbinding} of the interface from the top of the wall, which is accompanied by a rapid but continuous flattening of its shape. Using a nonlocal density functional theory and mesoscopic interfacial models all the regimes are discussed in some detail to reveal the complexity of the entire process and subtle aspects that affect its behaviour. In particular, it is shown that the nature of the depinning phenomenon is governed by the width of the wall pillars (separating grooves), whilst the grooves width only controls the location of the depinning first-order transition, if present.

description: There is no universally accepted definition of the category of "rural area" in Hungary and this issue is the subject of controversy. The EU or OECD standards cannot be fully applied due to unique national characteristics. As a) the role of agriculture in the national economy has drastically decreased in the last 15 years in Hungary - due to the political transition and globalisation, and as b) this decreasing importance causes heavy and pressing problems, especially in agricultural and ex-agricultural areas and regions, job loss is a characteristic sign of the underprivileged areas, and that affects mainly the villages and rural people who have lost their jobs in the agricultural sector. Main goal of the author's Ph.D. research is an analysis of the economical strategies of rural micro-regions depressed by agricultural unemployment. During this analysis a survey of the possibilities and plans of local people, civil organizations, entrepreneurs and local governments will be made. According to this Ph.D. research - from the point of view of employment and rural people - those areas where the rate of agricultural employees (% of total civilian employment) dropped significantly between 1990 and 2001 and where this caused permanent job-loss and unemployment are emphasized as "rural or special rural areas". After analysing the new role of agriculture in the national economy and in the life of the countryside in Hungary, these areas and the effects of the changes (mainly that influence rural employment) have been searched, as a first step in this research. The paper - as the second step - provides a short overview on the effects of the changes, the new role of agriculture and collects the micro-regions that are mainly depressed by agricultural job-loss, comparing these areas with different rural development categories used in Hungary and in the EU as well.
International Migration and Stereotype Formation: Indonesian Migrants in Hong Kong

description: This article analyses the impact of international migration on the formation and maintenance of stereotypes about the ethnic and national identities of migrant workers. It demonstrates that the employment conditions of Indonesian domestic workers in Hong Kong encourage certain types of behaviour, which in turn contribute to the processes of stereotype formation and maintenance about them in the host society. Intergroup contact theory predicts that even superficial interaction should disconfirm existing stereotypes, but this article shows how the ‘context of reception’ in host societies prevents this from happening through its creation of sub-optimal conditions, such as unequal power relationships.

description: Multiple Classifier Systems (MCSs) allow evaluation of the uncertainty of classification outcomes that is of crucial importance for safety critical applications. The uncertainty of classification is determined by a trade-off between the amount of data available for training, the classifier diversity and the required performance. The interpretability of MCSs can also give useful information for experts responsible for making reliable classifications. For this reason Decision Trees (DTs) seem to be attractive classification models for experts. The required diversity of MCSs exploiting such classification models can be achieved by using two techniques, the Bayesian model averaging and the randomised DT ensemble. Both techniques have revealed promising results when applied to real-world problems. In this paper we experimentally compare the classification uncertainty of the Bayesian model averaging with a restarting strategy and the randomised DT ensemble on a synthetic dataset and some domain problems commonly used in the machine learning community. To make the Bayesian DT averaging feasible, we use a Markov Chain Monte Carlo technique. The classification uncertainty is evaluated within an Uncertainty Envelope technique dealing with the class posterior distribution and a given confidence probability. Exploring a full posterior distribution, this technique produces realistic estimates which can be easily interpreted in statistical terms. In our experiments we found out that the Bayesian DTs are superior to the randomised DT ensembles within the Uncertainty Envelope technique.

description: Farmers in peri-urban regions face many problems, among which land scarcity is a major one according to literature. However, as indicated by a survey among farmers in the peri-urban region around Brussels, land scarcity is not perceived as a problem by all farmers to the same extent. Based on econometric analysis, the survey results show that perception of land scarcity is mainly influenced by differences in landownership and perceived ratio between farm land prices and real land prices. Changes in each of these variables will lead to a shift in the problems a farmer faces and will therefore stimulate different farming or land use strategies.

description: We simulate the two-dimensional fluid flow around National Advisory Committee for Aeronautics (NACA) 0012 airfoil using a hybrid lattice Boltzmann method (HLBM), which combines the standard lattice Boltzmann method with an unstructured finite-volume formulation. The aim of the study is to assess the numerical performances and the robustness of the computational method. To this purpose, after providing a convergence study to estimate the overall accuracy of the method, we analyze the numerical solution for different values of the angle of attack at a Reynolds number equal to $10^3$. Subsequently, flow fields at Reynolds numbers up to $10^4$ are computed for a zero angle of attack configuration. A grid refinement scheme is applied to the uniformly spaced component of the overlapping grid system to further enhance the numerical efficiency of the model. The results demonstrate the capability of the HLBM to achieve high accuracy near solid curved walls, thus providing a viable alternative in the realm of off-lattice Boltzmann methods based on body-fitted mesh.

description: Measurements are presented of inclusive charm and beauty cross sections in e^+p collisions at HERA for values of photon virtuality 12 \le Q^2 \le 60 GeV^2 and of the Bjorken scaling variable 0.0002 \le x \le 0.005. The fractions of events containing charm and beauty quarks are determined using a method based on the impact parameter, in the transverse plane, of tracks to the primary vertex, as measured by the H1 vertex detector. Values for the structure functions F_2^{c\bar{c}} and F_2^{b\bar{b}} are obtained. This is the first measurement of F_2^{b\bar{b}} in this kinematic range. The results are found to be compatible with the predictions of perturbative quantum chromodynamics and withprevious measurements of F_2^{c\bar{c}}.

Subjects: subject: Mechanical Engineering

description: Electric motor is a prominent rotary machinery in many engineering applications due to its excellent electrical energy utilization. With the increased demand in production and complex operating conditions, motors often run in a severe loading condition. Overload, overheating and many other intricate operating conditions account for the stator related faults in motors. Motor current signature analysis (MCSA) and vibration analysis have been popular techniques to diagnose different stator and rotor related faults in motors. But it is difficult to find the fault magnitude or fault threshold by using only one approach due to nonstationary motor operations. This paper presents a comprehensive review of a permanent magnet brushless DC motor’s (BLDC motor) fault diagnosis combining vibration and current signals collected from sensors. Since the insulation break in the stator winding is the most commonly occurring fault in the stator, a short-circuit was artificially created between two windings. Based on the motor operating conditions, three health states are chosen from the experimental sensor data with different fault magnitudes. Health states are labeled as healthy state, incipient failure state, and severe failure state. Two effective fault diagnosis indices named kurtosis and third harmonic of motor current are selected for analyzing the vibration signals and current signals, respectively. Proposed diagnostics framework is validated using experimental data and proven to detect the stator fault at the early stage as well as distinguish between different fault states. Monitoring both mechanical and electrical characteristics of BLDC motor provides a thorough understanding of fault magnitude and threshold in different health states.

description: This article presents a 3D geographic information systems (GIS) modeling and simulation of water flow in a landscape defined by a digital terrain model, provided by some available geolocation APIs. The proposed approach uses a cellular automata based algorithm to calculate water flow dynamic. The methodology was tested on a case study area of 27kmx19km located in Tangier, north of Morocco. In fact, we aim to detect flood zones in order to prevent problems related to space occupation in urban and rural regions. Some indices can be deduced from the stream shape using Cellular Automata (CA) based approach that can reduce the complexity related to space structures with multiple changes. A spatiotemporal simulation of the runoff process is provided using 3D visualization that we can pair with geographical information system tools (GIS). The 3D GIS modeling approach that was developed for the analyses of flood zones detection using a runoff model based on cellular automata was comprised of three main steps: Input (collection of data), calculation (CA tool) and visualization (3D simulation).

description: We construct a model for the space of automorphisms of a connected p-compact group in terms of the space of automorphisms of its maximal torus normalizer and its root datum. As a consequence we show that any homomorphism to the outer automorphism group of a p-compact group can be lifted to a group action, analogous to a classical theorem of de Siebenthal for compact Lie groups. The model of this paper is used in a crucial way in our paper ``The classification of 2-compact groups'', where we prove the conjectured classification of 2-compact groups and determine their automorphism spaces.

description: The impact of current nitrate policy measures in Flanders is estimated. A modular modelling system has been developed for comparing response and pressure indicators and for decomposing the response impact of policy measures. Compared to 1990, the internalised manure surplus is reduced to zero, whereas the distance to target of the soil surface balance to the water quality standard dropped only with 58%. Source-linked and sink-related measures each account for about the half of the manure surplus reduction. The impact of abatement technologies is minor. The modular approach helps to unravel the discrepancy between pressure and response and to propose policy alternatives.

description: We examine in a dynamic framework how public resources should be allocated to small-scale water protection efforts in agriculture or alternatively to investments in large-scale waste water treatment plants to control point source loads. The building of waste water treatment capacity is characterized by high set-up costs as compared to the operating costs. We determine the optimal timing of investment, the rate of nutrient load reduction from point versus non-point sources, and the optimal switching policies from control of non-point pollution only to control of both non-point and point sources. The results of the analytical model are illustrated with simulation of optimal abatement policies for the Finnish coastal waters in the Gulf of Finland.

description: Brushless DC (BLDC) motors, bearing the characteristics of permanent magnet synchronous machines, have gained immense popularity in industrial applications due to its excellent efficiency and ease in control over conventional DC motors. Stator related faults are the most common types of faults in BLDC motors while operating under a higher loading and complex condition. Conventional machine learning (ML) classifiers such as-Support Vector Machines (SVM), k-nearest neighbors (KNN), Naïve Bayes (NB) classifiers fail to obtain optimum accuracy when there are abrupt changes in health states of the BLDC motor. Especially the classification of weak health features ends up with an erroneous result. Boosting techniques allow adding weights to weak features and a better result in classification. This study presents an improved stator related fault classification of BLDC Motor using AdaBoost technique. Several parameters of AdaBoost algorithm are optimized and implemented along with Random Forest (RF) classifier in order to determine a developed algorithm for fault classification.
Irregular Mass Transfer in the Polars VV Puppis and V393 Pavonis during the Low State

description: The polars VV Pup and V393 Pav were observed with XMM-Newton during states of low accretion rate with peak X-ray luminosities of ~1 x 10^30 and ~1 x 10^31 erg/s, respectively. In both polars, accretion onto the white dwarf was extremely irregular, and the accretion rate varied by more than 1 order of magnitude on timescales of ~1 hr. Our observations suggest that this type of irregular accretion is a common phenomenon in polars during the low state. The likely cause of the accretion rate fluctuations are coronal mass ejections or solar flares on the companion star that intermittently increase the mass transfer into the accretion stream. Our findings demonstrate that the companion stars in cataclysmic variables possess highly active atmospheres.

description: Tungsten carbide (WC) contacts have been investigated as a novel gold-free Schottky metallization for AlGaN/GaN heterostructures. The evolution of the electrical and structural/compositional properties of the WC/AlGaN contact has been monitored as a function of the annealing temperature in the range from 400 to 800°C. The Schottky barrier height ($Φ$B) at WC/AlGaN interface, extracted from the forward current-voltage characteristics of the diode, decreased from 0.8 eV in the as-deposited and 400°C annealed sample, to 0.56 eV after annealing at 800 °C. This large reduction of $Φ$B was accompanied by a corresponding increase of the reverse bias leakage current. Transmission electron microscopy coupled to electron energy loss spectroscopy analyses revealed the presence of oxygen (O) uniformly distributed in the WC layer, both in the as-deposited and 400°C annealed sample. Conversely, oxygen accumulation in a 2-3 nm thin W-O-C layer at the interface with AlGaN was observed after the annealing at 800 °C, as well as the formation of W2C grains within the film (confirmed by X-ray diffraction analyses). The formation of this interfacial W-O-C layer is plausibly the main origin of the decreased $Φ$B and the increased leakage current in the 800°C annealed Schottky diode, whereas the decreased O content inside the WC film can explain the reduced resistivity of the metal layer. The results provide an assessment of the processing conditions for the application of WC as Schottky contact for AlGaN/GaN heterostructures.

The description is carried out taking into account the chiral shielding of the putative $σ(600)$ meson and it's mixing with the well-established $f_0(980)$ meson. It is shown that the data don't contradict the existence of the $σ(600)$ meson and yield evidence in favor of the four-quark nature of the $σ(600)$ and $f_0(980)$ mesons.

description: We introduce an epidemic spreading model on a network using concepts from percolation theory. The model is motivated by discussing the standard SIR model, with extensions to describe effects of lockdowns within a population. The underlying ideas and behavior of the lattice model, implemented using the same lockdown scheme as for the SIR scheme, are discussed in detail and illustrated with extensive simulations. A comparison between both models is presented for the case of COVID-19 data from the USA. Both fits to the empirical data are very good, but some differences emerge between the two approaches which indicate the usefulness of having an alternative approach to the widespread SIR model.

We re-analyzed RXTE data of the bright systems XTE J1859+226, XTE J1550-564 and GX 339-4, which show all three of them. We review the main properties of these LFQPOs and show that they follow a well-defined correlation in a fractional rms vs. softness diagram. We show that the frequency behavior through this correlation presents clear analogies with that of Horizontal-, Normal- and Flaring-Branch Oscillations in Z sources, with the inverse of the fractional rms being the equivalent of the curvilinear coordinate Sz through the Z track.

description: Kleine und mittlere Unternehmen in Deutschland stehen beim Übergang zu einer nachhaltigen Kreislaufwirtschaft vor großen Herausforderungen. Die Anwendung von künstlicher Intelligenz stellt eine Möglichkeit dar, den Übergang zu beschleunigen und positive Ergebnisse zu erzielen. Diese Studie untersucht sowohl die Chancen als auch die Schwierigkeiten und Herausforderungen, die auf kleine und mittlere Unternehmen beim Übergang zu einer Kreislaufwirtschaft zukommen könnten, wenn dieser Übergang mit Unterstützung von künstlicher Intelligenz-basierter Technologie verbunden ist. Wissenschaftliche Untersuchungen zeigen, dass kleine und mittlere Unternehmen mit dem Einsatz von Datenanalyse und -modellierung, Entscheidungsunterstützungssystemen, „maschinellem“ Lernen und „tiefgehendem“ Lernen kreislauffähige Güter herstellen, Ressourcenströme optimieren und nachhaltigere Geschäftsmodelle entwickeln können. Die Nutzung oder Implementierung von künstlicher Intelligenz in der Praxis erfordert jedoch besondere Fachkenntnisse und Ressourcen. Bei dem Übergang zu einer Kreislaufwirtschaft muss die gesamte Wertschöpfungskette betrachtet werden. Sämtliche Geschäftsmodelle bedürfen einer gründlichen Überarbeitung. Auch Fragen des Datenschutzes, der Sicherheit sowie der Ethik der künstlichen Intelligenz sind in diesem Zusammenhang von Relevanz. Die Ergebnisse dieser Thesis können kleinen und mittleren Unternehmen dabei helfen, einen reibungslosen Übergang zu einer nachhaltigen Kreislaufwirtschaft mit dem Einsatz von künstlicher Intelligenz zu ermöglichen.

We use two recent analytical instruments: non-stationary panel analysis and dynamic distribution analysis. Both tools overcome the problems involved in using standard cross-section analysis. The results of the non-stationary panel analysis show that the EU regions are converging, and that family farm income is converging faster than net added value. In the US states the analysis shows that substantial differences in farm income persist, and there are no evident signs of convergence.

description: In this work a new model for joint distribution of significant wave height and zero-up-crossing period is proposed. The model uses the significant steepness as a random variable in order to improve the fit at the wave breaking limit. As the exponentiated Weibull distribution is used for both the independent wave height and the conditional steepness, the model is named EW model. The model is developed based on a train dataset of 161 buoys and then compared to two reference models (OMAE2020 and DNVGL), using the second part of the measurement data as a test dataset. The normalized deviation is selected as a metric for evaluation. The EW model performs better than the reference models for 111 buoys. The sharp modeling of the wave breaking limit can be seen as a significant characteristic of this model.

description: Nonreciprocal photonic devices play a significant role in regulating the propagation of electromagnetic waves. Here we theoretically investigate the nonreciprocal properties of transverse magnetic modes in a one-dimensional graphene-based photonic crystal subjected to an applied electrical DC bias. We find that drifting electrons driven by the external DC electric field can give rise to extremely asymmetric dispersion diagrams. Furthermore, when the drifting electrons travel antiparallel to the normal component of the incident wave vector, the negative refraction is strongly suppressed, causing the energy of light to flow along the direction of the direct electric current. Our theoretical findings can be used to design nonreciprocal nanophotonic devices and enable light to propagate without refraction.

description: Tree clearing is widely practised in Queensland to develop exotic pastures to enhance pasture production and hence the financial gains. One of the major woodland community i.e. brigalow (Acacia harpop hylla) was targeted for clearing in the early 1950s due to its fertile soils. Recently, some marginal communities such as Poplar box (Eucalyptus populnea) and Iron bark (Eucalyptus melanophloia) are targeted for clearing. Net benefits from clearing woodlands to increase pasture production, hence cattle production, is questioned in this paper. Previous studies have emphasised the gains in pasture yield over <10-15 years of clearing, without considering any long term ecological effects. The questions are whether an increase in pasture production following clearing is sustainable over a long term (>15 yrs.) or whether such an increase is 'actually beneficial' and does not result in any adverse in-situ and ex-situ ecological effects on grazing systems? The study is based on detailed ecological data on pasture production, soil properties (biological and physicochemical), litter production and nutrient recycling, and pasture plant diversity and diet quality. For this, three tree communities i.e. A. harpophylla, E. melanophloia and E. populnea were selected in central Queensland. There were three different ages of clearing i.e. 5 yr, 11-13 yr and 33 yr for each of the tree community. Comparisons were made for paired plots between cleared and uncleared (intact) woodlands across 3 age groups of clearing. An economic analysis was conducted of tangible (pasture yield) and intangible parameters (soil properties, plant diversity and diet quality, and nutrients recycled through litter). The total assessment for pasture yield and various ecological parameters across 3 different age groups of clearing and their paired uncleared plots provides information for the land holders, policy makers and land managers to make decisions on tree clearing for pasture development considering the long term ecological effects.

description: We show that geometrically coupled polariton condensates fabricated in semiconductor devices are versatile systems capable of simulating molecules with given characteristics. In particular, we consider oscillatory and stationary symmetric and asymmetric states in polariton dimers, trimers, and tetrads and their luminosity in real and Fourier space. The spectral weights of oscillatory states are associated with discrete spectral lines. Their number and separation can be controlled by changing the number and geometry of condensates, reflected by the coupling strengths. We also show that asymmetric stationary states combine discrete and continuous degrees of freedom in one system. The continuous degree of freedom is represented by the phase while the discrete degree of freedom is given by density asymmetry. Our work paves the way to engineer controllable artificial molecules with a range of properties manufactured on demand.

description: The reliability and performance of a system with minimum life-cycle cost have become quite prominent in engineering systems. With increasing industrial applications, machines are operating in intricate conditions with higher uncertainty, causing greater vulnerability of system failure. This paper reports fault-related information of Brushless DC Motor (BLDC motor) in non-stationary operating conditions and presents several analyses to diagnose the faults. Fault diagnosis is the most crucial and important part of system prognostics which helps to increase the remaining useful life (RUL) and prevent catastrophic failures. Having both electrical and mechanical characteristics present in a BLDC motor, it shows several faults in different operating conditions. These faults cause a significant change in the vibration of the Motor. This paper deals with the anomaly detection of BLDC motor in non-stationary speed conditions using vibration signal analysis as well as extraction of several Condition Indicators (CI).

description: This paper deals with the problem of autonomous navigation of a mobile robot in an unknown 2D environment to fully explore the environment as efficiently as possible. We assume a terrestrial mobile robot equipped with a ranging sensor with a limited range and 360 degrees field of view. The key part of the exploration process is formulated as the d-Watchman Route Problem which consists of two coupled tasks - candidate goals generation and finding an optimal path through a subset of goals - which are solved in each exploration step. The latter has been defined as a constrained variant of the Generalized Traveling Salesman Problem and solved using an evolutionary algorithm. An evolutionary algorithm that uses an indirect representation and the nearest neighbor based constructive procedure was proposed to solve this problem. Individuals evolved in this evolutionary algorithm do not directly code the solutions to the problem. Instead, they represent sequences of instructions to construct a feasible solution. The problems with efficiently generating feasible solutions typically arising when applying traditional evolutionary algorithms to constrained optimization problems are eliminated this way. The proposed exploration framework was evaluated in a simulated environment on three maps and the time needed to explore the whole environment was compared to state-of-the-art exploration methods. Experimental results show that our method outperforms the compared ones in environments with a low density of obstacles by up to 12.5%, while it is slightly worse in office-like environments by 4.5% at maximum. The framework has also been deployed on a real robot to demonstrate the applicability of the proposed solution with real hardware.

description: In this paper we analyze the impact of the EU multi-level co-financing system on regional policy-making and priority setting taking the case of the agri-environmental program of Saxony-Anhalt in Germany. The implications of several co-financing scenarios are analyzed and compared to respective lump-sum transfers using an interactive linear programming approach. The results reveal that regional choices on agri-environmental measures are strongly influenced by the co-financing system leading to distortions. The extent of these distortions depends on the specific regional preferences and restrictions to be considered in the policy-making process.

Trabalhar artisticamente com elementos que possuem a possibilidade de reconstruir a memória de meus ancestrais, permite a restituição de narrativas negligenciadas e a construção de novas. Uma possibilidade subjetiva que esse processo de pesquisa artístico acionou e procurou instaurar, ressignificando discursos. Como um resultado possível através da materialidade do sangue, que a forma artística deu aos rastros encontrados em trajetos percorridos da memória. Palavras-chave: Sangue, Rastros, Memória, Miscigenação e Ancestralidade The erasure of fundamental parts of memory often makes the survival of different social groups unfeasible, as in this case, those of Afro-indigenous origins. Working artistically with elements that have the possibility to reconstruct the memory of my ancestors, allows the restitution of neglected narratives and the construction of new ones. A subjective possibility that this artistic research process triggered and sought to establish, reframing discourses. As a possible result through the materiality of the blood, which the artistic form gave to the tracks found in paths traveled through memory.

The Only Undoable CRDTs are Counters

description: In comparing well-known CRDTs representing sets that can grow and shrink, we find caveats. In one, the removal of an element cannot be reliably undone. In another, undesirable states are attainable, such as when an element is present -1 times (and so must be added for the set to become empty). The first lacks a general-purpose undo, while the second acts less like a set and more like a tuple of counters, one per possible element. Using some group theory, we show that this trade-off is unavoidable: every undoable CRDT is a tuple of counters.
