description: Some issues and features related to nonlinear dynamics are examined for a classical model of jet airplane in this study. Concretely these nonlinear features may imply unexpected events and it is then important to evaluate if there are dangerous or not. Normally they are linked to the real behaviour and physics of an aircraft but may also explain how a simulator (unexpectedly) reacts in certain circumstances. Here the (mainly) analysed model is the Bizjet full-scale aircraft which is provided by Professor R. F. Stengel for study purposes (in both his homepage and classical textbook [1] with characteristics closed to a Learjet). In order to perform the nonlinear analysis, the Matcont toolbox [2] is mainly employed. Amongst others in this work, state jumps are observed and give rise to a nonzero bank angle during classical longitudinal flights. The phenomenon is described mathematically by means of a bifurcation diagram which exhibits some real (pitchfork) bifurcations. In order to cope with this problem, the dangerous zone is delimited by tracing the locus of bifurcation points (in the plane of the longitudinal control parameters). There may also be some Hopf bifurcations which create periodical orbits suddenly. All the predicted behaviours are illustrated and corroborated with time simulations. Moreover, this type of T-tail aircraft can be responsible for a deep stall phenomenon. By calculating the basin of attraction, we try to delimit the zone of initial conditions leading to such a phenomenon. More generally a diagnosis of the deep stall prone configurations is made (especially aft centred aircrafts) in order to avoid them. A loss-of-control can besides present an important transient nature. There is a need to explore the response of the aircraft with huge excitations or values far from the equilibrium taking into account unsteady aspects. In this case, the qualitative results depend no more on the local properties and other ways must be employed to diagnose correctly the situation during the upstream analysis part which improves understanding (and permits to avoid numerous time simulations). Finally, one hope is to contribute to the pre-design of a jet airplane so as to avoid such events and to diminish the associated risks. In order to be mathematically rigorous (for researchers) and meaningful (for aerospace engineers or pilots), for every addressed critical points, the mathematical analysis and the underlying physics are both exposed. The point-of-view of the pilot is also investigated and proposals of training exercises (on simulator) for loss-of-control are formulated. [1] Stengel, R. F. Flight dynamics.

title: Temperature Effect on the Mechanical Properties of Steel Fiber Reinforced Ultra-High-Performance Concrete
Creators: name: Gomes, Jenny Bernadette
Publisher: name: Utah State University
Year: 2021

description: The contemporary innovation in concrete technology is ultra-high-performance concrete (UHPC). In this work, mechanical properties of UHPC are studied at ambient terrestrial temperature conditions. Specimens are prepared under laboratory environments maintaining the temperature of -25°C, -5°C, 15°C, 35°C, and 55°C. A freeze thaw chamber is utilized to condition the specimens at specified temperatures. Compressive strength, flexural strength, toughness, and modulus of elasticity are determined under varying temperature and steel fiber volume content. The results indicate that both temperature and steel fibers have effect on the mechanical properties of UHPC. The flexural and compressive strength show an opposite trend of strength under the temperature variations. Effect on modulus of elasticity is similar to compressive strength. Numerical relations are developed among modulus of elasticity and compressive strength isolating both temperature and steel fiber volume.

description: The study examined cooperative membership status and adoption of good agronomic practices (GAPs) among cocoa farmers in the Atwima Mponua District of Ashanti Region, Ghana. Data was collected from 400 cocoa farmers selected using the multistage sampling technique. Statistical analytical tools such as mean, standard deviation, frequency, percentage, ordered logit regression model, independent samples t-test and chi-square test of independence were used. The study showed a high level of awareness, knowledge, and skills on GAPs among the farmers. Membership status (active and non-active) was found to have a statistically significant association with adoption of GAPs. Gender, household size, age of farmer and access to extension services were the other factors that influenced adoption of GAPs. There was a statistically significant difference in yields and income of active and non-active members. The study recommends that the Ghana Cocoa Board (COCOBOD) should develop a policy that could enable it to continue to work with only cooperatives. Also, existing cooperatives should be empowered to encourage active participation by all members to ensure that more GAPs are continually adopted. This can also result in higher yields and income.

description: На современном этапе развития территориальные кластерные структуры выступают как наиболее устойчивые сегменты региональной экономической системы. Кластерные связи и коммуникации, возникающие в кластере, дают широкие возможности для обеспечения конкурентных преимуществ и наивысшей эффективности на соответствующих рынках. Региональный кластер состоит из так называемого ядра кластера – группы хозяйствующих субъектов, производящих конечную продукцию и реализующих ее за пределами этой территории. В качестве основных параметров, характеризующих состояние ядра кластера, выступают конкурентоспособность производимой продукции и уровень конкуренции внутри ядра кластера. Эксперты отмечают, что в большинстве регионов страны кластеры создаются стихийно. Процессы кластеризации подведомственных территорий, являющихся объектом управления соответствующих органов власти, существенно изменили представление о сути и способах современных подходов к организации системы стратегического управления социо-эколого-экономическим развитием регионов. Такое положение требует уточнить понятие инновационного центра кластера; выявить взаимосвязь основных составляющих, реализующих взаимодействие кластерных коммуникаций; установить основные зависимости, воздействующие на динамику развития кластера; рассмотреть особенности развития социальной сферы и, в частности, туристско-рекреационного кластера депрессивных республик Северного Кавказа. Все вышеизложенное обусловливает актуальность заданной темы исследования и необходимость решения ряда научных задач, в т.ч. по выявлению и исследованию особенностей организационно-управленческого механизма формирования и развития туристско-рекреационных кластеров.

description: The starbusting, nearby (D = 32.9 Mpc) spiral (Sc) galaxy NGC2276 belongs to the sparse group dominated by the elliptical galaxy NGC2300. NGC2276 is a remarkable galaxy, as it displays a disturbed morphology at many wavelengths. This is possibly due to gravitational interaction with the central elliptical galaxy of the group. Previous ROSAT and XMM-Newton observations resulted in the detection of extended hot gas emission and of a single very bright (~1.e41 erg/s) ultraluminous X-ray source (ULX) candidate. Here we report on a study of the X-ray sources of NGC2276 based on CHANDRA data taken in 2004. CHANDRA was able to resolve 16 sources, 8 of which are ULXs, and to reveal that the previous ULX candidate is actually composed of a few distinct objects. We construct the luminosity function of NGC2276, which can be interpreted as dominated by high mass X-ray binaries, and estimate the star formation rate (SFR) to be ~5-15 Msun/yr, consistent with the values derived from optical and infrared observations. By means of numerical simulations, we show that both ram pressure and viscous transfer effects are necessary to produce the distorted morphology and the high SFR observed in NGC2276, while tidal interaction have a marginal effect.

description: First-principles calculations within the DFT are employed to investigate the relationship between the electronic structure and the unexpected features of the hexagonal cell parameters of YbAuIn and Yb$_{3}$AuGe$_{2}$In$_{3}$. Calculations indicate that YbAuIn is an intermediate valent system with one Yb 4\textit{f} state pinned to the Fermi level, while Yb$_{3}$AuGe$_{2}$In$_{3}$ is closer to integer valency with all Yb 4\textit{f} states occupied. Structural relaxations performed on LaAuIn and LuAuIn analogs reveal that expansion of the \textit{c}-parameter in Yb$_{3}$AuGe$_{2}$In$_{3}$ is attributable to larger size of the divalent Yb compared with intermediate valent Yb.

description: Trojanized software packages used in software supply chain attacks constitute an emerging threat. Unfortunately, there is still a lack of scalable approaches that allow automated and timely detection of malicious software packages and thus most detections are based on manual labor and expertise. However, it has been observed that most attack campaigns comprise multiple packages that share the same or similar malicious code. We leverage that fact to automatically reproduce manually identified clusters of known malicious packages that have been used in real world attacks, thus, reducing the need for expert knowledge and manual inspection. Our approach, AST Clustering using MCL to mimic Expertise (ACME), yields promising results with a F1 score of 0.99. Signatures are automatically generated based on characteristic code fragments from clusters and are subsequently used to scan the whole npm registry for unreported malicious packages. We are able to identify and report six malicious packages that have been removed from npm consequentially. Therefore, our approach can support the detection by reducing manual labor and hence may be employed by maintainers of package repositories to detect possible software supply chain attacks through trojanized software packages.

description: Academia currently ranks academics and the ranking is mainly based on one single, flawed number, the h-index. This proposal suggest to move forward to ProAc (www.fabiocrameri.ch/proac), a data-based, visual toolbox that allows to profile academics based on not just one, but a selection of elaborate indices. Crucially, this will reduce unnecessary competition between academics and current ranking biases, and foster high-quality, instead of high-quantity, research. And it will provide funding to a keen academic. Support this project, and its PI, here.

description: Особенностью последнего времени является повышенный интерес российских компаний к проблемам построения корпоративной социальной ответственности. И это естественно, ибо интегрирование в глобальные экономические процессы, стремление попасть в число лидеров на международных рынках заставляет отечественные компании увеличивать корпоративную прозрачность, социальную ответственность и эффективность. Социальное позиционирование корпоративной социальной ответственности позволяет компаниям широко заявлять о себе в обществе, активно продвигать свои ценности и позиционироваться как надежный работодатель и прогрессивное предприятие. Все это позволяет рассматривать концепцию корпоративной социальной ответственности как капиталообразующую для корпоративной структуры. Очередной мировой экономический кризис, отягощенный санкциями и пандемией, делает невозможным использовать традиционный социально-экономический курс и инструментарии. Это требует иного вектора социально-экономического развития страны на качественно другом уровне, основанного на тесном взаимовыгодном сотрудничестве бизнес-структур, государства и общества, предполагающего более высокий социальный капитал. В числе основных задач реализации нового стратегического курса устойчивого социально-экономического развития РФ нужно отметить необходимость оперативного разрешения макроэкономических проблем на уровне государства, оптимизацию бизнес-процессов компаниями, обеспечение высокого спроса на отечественную продукцию и услуги со стороны общества. Высокая ориентированность на качественные результаты позволяет мобилизовать ресурсы, эффективно реализовать потенциал экономического роста вне зависимости от внешней конъюнктуры рынка. В этих условиях необходимо научиться правильно интегрировать причинно-следственные связи, суметь увидеть, что кризисы, помимо угроз, также несут потенциал больших возможностей. Все это и сподвигло нас взяться за исследование особенностей формирования корпоративной социальной ответственности бизнес-структур как нового фактора устойчивого развития в условиях текущей экономической конъюнктуры.

description: We describe a criterion for the detection of entanglement between two multi-boson systems. The criterion is based on calculating correlations of Gell-Mann matrices with a fixed boson number on each subsystem. This applies naturally to systems such as two entangled spinor Bose-Einstein condensates. We apply our criterion to several experimentally motivated examples, such as an $ S^z S^z $ entangled BECs, ac Stark shift induced two-mode squeezed BECs, and photons under parametric down conversion. We find that entanglement can be detected for all parameter regions for the most general criterion. Alternative criteria based on a similar formalism are also discussed together with their merits.

description: Since 2017 the e-WindLidar initiative has been pursuing the goal of including expert lidar knowledge in tools that will facilitate the application of lidar technology. The initiative yielded several open-source tools such as campaign-planning-tool, YADDUM and mocalum, which are provided as Python packages. campaign-planning-tool is a result of experience and knowledge accumulated after almost a decade of planning and configuring scanning lidar measurement campaigns. It provides users with a set of methods that will allow them to optimize measurement positions, generate GIS layers which facilitate placement of lidars, optimize and synchronize trajectories for multiple lidars, export results in human and machine-readable formats, and more. YADDUM (Yet Another Dual-Doppler Uncertainty Model) is focused on delivering a simple yet effective dual-Doppler uncertainty model. The model is based on the law of propagation of uncertainties. YADDUM is applicable for wind lidars and radars. mocalum is a package for Monte-Carlo based lidar uncertainty modeling. It preforms fast Monte-Carlo simulations. It can simulate both single and multi lidar configurations. mocalum handles arbitrary trajectories (i.e., complex trajectories) as well IVAP (sector-scan) trajectories. It provides means to generate 3D or 4D, uniform or turbulent flow fields and has a built-in 2nd order kinematic model for calculation of trajectory timing. Results of the mocalum simulations are provided as xarray datasets enriched with metadata ready to be exported as NetCDF files, shared and published for reuse. In this talk, we will present the above describe tools and show examples on how to interact with them.

description: A Climated-Friendly Future Single-Aisle Airliner for Europe In the frame of this contribution, precisely, an integrated aircraft concept for an airliner is presented, which combines advanced economic operation with meeting at the same time the present and upcoming challenging European climate targets. The concept is based on an European single-aisle commercial aircraft with around 150-200 seats and is able to be operated on a short- and medium-haul mission within all Europe. It will be hybrid-electric powered, with a hybridization ratio of 10-17% electric thrust in cruise, referring to the TOC at 77 000 kg cruise mass at Ma 0,78 and at 11 000 m altitude. The designated aircraft design is powered by turbofan engines of high bypass ratio. It features advanced aerodynamics. Emphasis will be placed on the application of newly-interpreted technologies, which can be adopted in the operation of European Airliners, already in the foreseeable future.

description: The dynamical response of edge waves under the influence of self-gravity is examined in an idealized two-dimensional model of a proto-stellar disc, characterized in steady state as a rotating vertically infinite cylinder of fluid with constant density except for a single density interface at some radius r0. The fluid in basic state is prescribed to rotate with a Keplerian profile $Ω_k(r)\sim r^{-3/2}$ modified by some additional azimuthal sheared flow. A linear analysis shows that there are two azimuthally propagating edge waves, kin to the familiar Rossby waves and surface gravity waves in terrestrial studies, which move opposite to one another with respect to the local basic state rotation rate at the interface. Instability only occurs if the radial pressure gradient is opposite to that of the density jump (unstably stratified) where self-gravity acts as a wave stabilizer irrespective of the stratification of the system. The propagation properties of the waves are discussed in detail in the language of vorticity edge waves. The roles of both Boussinesq and non-Boussinesq effects upon the stability and propagation of these waves with and without the inclusion of self-gravity are then quantified. The dynamics involved with self-gravity non- Boussinesq effect is shown to be a source of vorticity production where there is a jump in the basic state density, in addition, self-gravity also alters the dynamics via the radial main pressure gradient, which is a Boussinesq effect . Further applications of these mechanical insights are presented in the conclusion including the ways in which multiple density jumps or gaps may or may not be stable.

description: Although Nose's thermostated mechanics is formally consistent with Gibbs' canonical ensemble, the thermostated Nose-Hoover ( harmonic ) oscillator, with its mean kinetic temperature controlled, is far from ergodic. Much of its phase space is occupied by regular conservative tori. Oscillator ergodicity has previously been achieved by controlling two oscillator moments with two thermostat variables. Here we use computerized searches in conjunction with visualization to find singly-thermostated motion equations for the oscillator which are consistent with Gibbs' canonical distribution. These models are the simplest able to bridge the gap between Gibbs' statistical ensembles and Newtonian single-particle dynamics.

description: No ano em curso (2017), faz 150 anos da publicação da carta de lei de 1/7/1867, assinada por D. Luís I, Rei de Portugal, abolindo a pena de morte para os crimes civis, pelo que a Assembleia da República decidiu comemorar a efeméride, pela sua importância humanista, em Portugal e para exemplo do Mundo, em parceria com a Câmara Municipal de Lagos. A abolição da pena de morte para os crimes civis teve lugar acompanhada de uma profunda reforma penal e prisional. Foi ainda nesse ano de 1867 que foi aprovado o código civil de Seabra e decorridos dois anos (1869) teve lugar a abolição da escravatura negra em Portugal. Tais medidas legislativas surgiram no âmbito das correntes e ideais humanistas do iluminismo no Mundo e de forma particular em Portugal, pelo que se torna imperioso referenciar tais doutrinas e outras realidades económicas, filosóficas, políticas e legislativas da época. O conhecimento da abolição da pena de morte pela natureza dos crimes; os factos que podiam preencher a tipologia dos crimes para aplicação da pena de morte, bem como as últimas condenações e forma das execuções é por nós considerado importante, para além da referência dos Países que mantêm no seu quadro legal punitivo a aplicação da pena de morte e ainda os métodos de execução da pena capital, ajudam a melhor compreender a importância da Reforma Penal e Prisional no ano de 1867 em Portugal. Por se tratar de documentos fundamentais e na versão original, para melhor conhecer e interpretar tais medidas, publicam-se na íntegra em anexo a Carta de Lei de 1/7/1867 e também a Carta de Lei de 9/6/1870. As referências bibliográficas e legislativas constantes do texto, são também importantes para o leitor melhor poder conhecer e investigar algum dos temas tratados.

description: The performance of an Open cycle engine, as gas generator or expander bleed, is direct linked to the efficiency of its turbomachinery design and its optimization is, in most cases, focused in this component due to structural limitation or other options as gas generator temperature of dynamic stability in pressure drop minimization. Designing turbines for space engine application is always a compromise between turbine performance, engine performance and size. For instance, in open cycle, turbine flowrate should be as low as possible but a minimum is still needed to obtain the target shaft power. During the past year, as part of the CNES/DLR cooperation in the frame of Turbomachinery analysis, distinct design methods and its intrinsic characteristics were compared using common boundary conditions. In this frame, this article aims at analyzing the different design methodology for a supersonic partial admission impulse turbine for LRE as well as the impact of partial admission choices on the stator performance geometry but also on the rotor, as the optimal rotor geometry is strongly linked to the number of open stator nozzles, where both airfoil and axisymmetric nozzles are analyzed and compared.
Shared communicative acts in theatre texts in performance

description: This paper adopts a relevance theoretic approach to meaning making in theatrical texts and performances. Text-based theatrical performances are collaborative creative events, many of whose participants may never engage directly with an audience member, but all of whom are engaged in making and conveying meaning. Such texts communicate immediately to multiple audiences: readers, actors, directors, producers, and designers. They communicate less directly to the writer’s ultimate audience – the playgoer or spectator – through the medium of performance. But playgoers are not passive receptacles for interpretations distilled in rehearsal, enacted through performance, or developed in study and reflection. Rather, in the framework of communication postulated by relevance theory, the audience is an active participant in making meaning. I will briefly review a range of approaches to meaning making in theatre, and then outline my view of a relevance theoretic account of theatre texts and performances as related but distinct communicative acts. For Weimann (1992), discussing the German playwright, Heiner Müller, “language is first and foremost material with which the audience is expected to work so as to make and explore their own ‘experiences’” (p. 958). By contrast, T. S. Eliot characterised performances as ‘interruptions’ of the relationship between writer and audience; in ‘a true acting play’, he asserted, the actor added nothing (Eliot, 1924, p. 96). Campbell (1981) argues that “the theatre cannot gear its production to actual audiences”, as only the “finest and most appreciative of abstract audiences for that play” (p. 152) can properly grasp its meaning. For him, the disparate capacities, views, and expectations of a given audience present a profound challenge to theatre as communication. Connor (1999) addresses the same issue, pointing out that if readers can disagree about the meaning of a text, then spectators are even less likely to agree on what a given performance means (p. 417). Unlike Campbell, however, she regards this diversity as enriching, concluding that meanings “develop from co-production with spectators as subjects” (p. 426). Relevance theory provides a framework in which to begin to disentangle the overlapping and interacting, but equally vital, contributions of writer, company, and audience in making meanings.

description: Diaspora ist ein Begriff, der in Religion, sozialen Bewegungen, Wissenschaft und Politik zur Selbst- und Fremdbezeichnung verwendet wird. Dieser Beitrag analysiert die verschiedenen Bedeutungen des Diaspora-Begriffs und zeigt auf, wie sie sich historisch entwickelt haben und miteinander in Beziehung stehen. Im Judentum war Diaspora zunächst ein theologischer Begriff, der die ‚Zerstreuung‘ in der Welt als göttliche Strafe sowie eine mögliche Rückkehr und Wiedervereinigung des ‚auserwählten Volkes‘ bezeichnete. Heute werden jüdische Menschen, die außerhalb Israels leben, als Diaspora bezeichnet. Im Christentum gelten konfessionelle Gruppen, die sich in einer Region in der Minderheit befinden, als Diaspora. Die Bezeichnung afrikanische Diaspora dient insbesondere der kulturellen Identifikation. Das wissenschaftliche Feld der Diaspora Studien bildete sich entlang verschiedener, stetig breiter werdender Diaspora-Definitionen heraus und machte den Begriff anschlussfähig für die internationale Politik. Diaspora-Politiken von Regierungen zielen darauf, die internationalen Geld- und Wissenstransfers von Migrant:innen für ,entwicklungsrelevante‘ Projekte nutzbar zu machen. Der positiv aufgeladene Diaspora-Begriff aus der Entwicklungspolitik wurde zögerlich in die internationale Migrationspolitik aufgenommen und steht hier im starken Widerspruch zu den gewaltsamen Grenzpolitiken. Unter Doing Diaspora schließlich wird eine Analyseperspektive gefasst, die einer essentialistischen Vorstellung von Diaspora entgegenzuwirken versucht, indem sie Diaspora als Kategorie der Praxis versteht, die unterschiedliche Akteur:innen mit je spezifischen Absichten verwenden und inszenieren.

description: LMP-103S is a storable, green, ADN-based liquid monopropellant with significant potential owing to its improved specific impulse (? 6%) and density (~24%) in comparison to hydrazine, and its superior safety and handling characteristics. LMP-103S already has a significant history of thruster testing and flight heritage. However, its baseline combustion behavior is a surprisingly understudied topic. Constant-volume strand burner experiments with LMP-103S are reported herein for pressures between 0.69 34.5 MPa (100 5,000 psia). Linear burning rates are measured from transient pressure data and high-speed video. Visible and near-IR emission spectra are recorded, as well. Phenomenological combustion behaviors are reported for the entire pressure range as deduced from these diagnostics and two clear pressure regimes are observed. Hydrodynamic instabilities and supercritical combustion processes dominate the combustion behavior in the low- and high-pressure regimes, respectively. Supporting experiments include thermal cook-off of LMP-103S and impact sensitivity testing of ADN crystals extracted from LMP-103S solution. The data presented herein significantly expand upon those available in the literature for LMP-103S, and the phenomenological combustion behavior deduced from transient high-speed video data improve upon the state-of-the-art knowledge regarding ADN-based liquid monopropellants.
A probabilistic model to resolve diversity-accuracy challenge of recommendation systems

description: Recommendation systems have wide-spread applications in both academia and industry. Traditionally, performance of recommendation systems has been measured by their precision. By introducing novelty and diversity as key qualities in recommender systems, recently increasing attention has been focused on this topic. Precision and novelty of recommendation are not in the same direction, and practical systems should make a trade-off between these two quantities. Thus, it is an important feature of a recommender system to make it possible to adjust diversity and accuracy of the recommendations by tuning the model. In this paper, we introduce a probabilistic structure to resolve the diversity-accuracy dilemma in recommender systems. We propose a hybrid model with adjustable level of diversity and precision such that one can perform this by tuning a single parameter. The proposed recommendation model consists of two models: one for maximization of the accuracy and the other one for specification of the recommendation list to tastes of users. Our experiments on two real datasets show the functionality of the model in resolving accuracy-diversity dilemma and outperformance of the model over other classic models. The proposed method could be extensively applied to real commercial systems due to its low computational complexity and significant performance.

description: We present a statistical model of a dilute polymer solution in good solvent in the presence of low-molecular weight cosolvent. We investigate the conformational changes of the polymer induced by a change of the cosolvent concentration and the type of interaction between the cosolvent and the polymer. We describe the polymer in solution by the Edwards model, where the partition function of the polymer chain with a fixed radius of gyration is described in the framework of the mean-field approximation. The contributions of polymer-cosolvent and the cosolvent-cosolvent interactions in the total Helmholtz free energy are treated also within the mean-field approximation. For convenience we separate the system volume on two parts: the volume occupied by the polymer chain expressed through its gyration volume and the bulk solution. Considering the equilibrium between the two subvolumes we obtain the total Helmholtz free energy of the solution as a function of radius of gyration and the cosolvent concentration within gyration volume. After minimization of the total Helmholtz free energy with respect to its arguments we obtain a system of coupled equations with respect to the radius of gyration of the polymer chain and the cosolvent concentration within the gyration volume. Varying the interaction strength between polymer and cosolvent we show that the polymer collapse occurs in two cases - either when the interaction between polymer and cosolvent is repulsive or when the interaction is attractive. The reported effects could be relevant for different disciplines where conformational transitions of macromolecules in the presence of a cosolvent are of interest, in particular in biology, chemistry and material science.
