Numerical simulations of wind-driven protoplanetary nebulae. II. signatures of atomic emission

We follow up on our systematic study of axisymmetric hydrodynamic simulations of protoplanetary nebula. The aim of this work is to generate the atomic analogues of the H2 near-infrared models of Paper I with the ZEUS code modified to include molecular and atomic cooling routines. We investigate stages associated with strong $\mathrm{[Fe\, {\small II}] \, 1.64\, \mathrm{\mu m} }$ and $\mathrm{ [S\, {\small II}] \, 6716}$ Å forbidden lines, the $\mathrm{[O\, {\small I}]\, 6300}$ Å airglow line, and Hα 6563 Å emission. We simulate (80 ∼ 200 km s−1) dense (∼105 cm−3) outflows expanding into a stationary ambient medium. In the case of an atomic wind interacting with an atomic medium, a decelerating advancing turbulent shell thickens with time. This contrasts with all other cases where a shell fragments into a multitude of cometary-shaped protrusions with weak oblique shocks as the main source of gas excitation. We find that the atomic wind-ambient simulation leads to considerably higher excitation, stronger peak and integrated atomic emission as the nebula expands. The weaker emission when one component is molecular is due to the shell fragmentation into fingers so that the shock surface area is increased and oblique shocks are prevalent. Position-velocity diagrams indicate that the atomic-wind model may be most easy to distinguish with more emission at higher radial velocities. With post-AGB winds and shells often highly obscured and the multitude of configurations that are observed, this study suggests and motivates selection criteria for new surveys.
Socio-Economic Deprivation of Women Tea Plantation Labourers in Idukki District

: The scale to measure socio-economic deprivation was administered to 120 tea plantation labourers in Munnar, Pallivasal and Devikulam gramapanchayaths of Idukki district. The results revealed that the dimensions deprived were income, housing, other public services, social recognition, democratic participation and credit. The overall deprivation index computed were 2.165. It was also found that 56.67 per cent of the tea plantation labourers were highly deprived of the dimensions while 43.33 per cent tea plantation labourers had low level of deprivation of the dimensions.
Estudo Numérico do Escoamento Através de um Cilindro Oscilante Utilizando o Método de Fronteiras Imersas

O estudo de escoamentos atraves de cilindros e um problema classico em fuidodinâmica e tem atraido a atencao de centenas de autores devido a sua relevância na area cientifica e na engenharia. Este trabalho apresenta simulacoes numericas para um unico cilindro oscilando transversalvente a um escoamento em duas dimensoes. As equacoes de Navier-Stokes sao solucionadas numa malha cartesiana usando esque- mas de diferencas finitas para resolver as derivadas espaciais e um metodo de Runge-Kutta de baixa armazenagem para integracao no tempo. O cilindro e modelado usando o metodo de fronteiras imersas. A simulacao numerica e capaz de gerar series de tempo para a velocidade na posicao da sonda e suas analises auto-espectrais mostram as frequencias excitadas nas simulacoes. Assim, de modo que se possa identificar os padroes do desprendimento de vortices e validar a ocorrencia do fenomeno de sincroni- zacao (lock-in), foram simulados escoamentos tranversais sobre um cilindro oscilando senoidalmente, com diferentes combinacoes de frequencia e amplitude para cada simulacao. Por meio de analises do sinal do coeficiente de sustentacao, percebeu-se claramente a sincronizacao para os testes realizados den- tro da zona de lock-in. Alem disso, sao analisados os valores dos coeficientes de sustentacao e arraste, verificando-se assim suas variacoes devido a oscilacao imposta ao cilindro. Dessa forma, apos compara- dos com a literatura, todos os resultados obtidos se mostraram satisfatorios, demonstrando a consistencia do metodo de fronteiras imersas e sua aplicabilidade no estudo de escoamentos sobre obstaculos em movimento.
An Amalgamation of Hormone Inspired Arbitration 
Systems for Application in Robot Swarms

Previous work has shown that virtual hormone systems can be engineered to arbitrateswarms of robots between sets of behaviours. These virtual hormones act similarly to theirnatural counterparts, providing a method of online, reactive adaptation. It is yet to be shownhow virtual hormone systems could be used when a robotic swarm has a large variety of task typesto execute. This paper details work that demonstrates the viability of a collection of virtual hormonesthat can be used to regulate and adapt a swarm over time, in response to different environmentsand tasks. Specifically, the paper examines a new method of hormone speed control for energyefficiency and combines it with two existing systems controlling environmental preference as wellas a selection of behaviours that produce an effective foraging swarm. Experiments confirm theeffectiveness of the combined system, showing that a swarm of robots equipped with multiple virtualhormones can forage efficiently to a specified item demand within an allotted period of time.
Carregamento indutivo de corrente em laços supercondutores

Os supercondutores de baixa temperatura critica podem conduzir correntes persistentes praticamente sem perdas, pois a tecnica para realizar as emendas esta bem desenvolvida e as perdas resistivas sao despreziveis. A substituicao desses supercondutores por supercondutores de alta temperatura critica pode reduzir muito o custo com refrigeracao, contudo, as perdas resistivas relacionadas as emendas ainda sao relevantes. Bobinas fabricadas com lacos de fitas supercondutoras de alta temperatura critica nao possuem emendas, e portanto podem transportar correntes em modo persistente. Como nao ha terminais, sua corrente deve ser induzida atraves de tecnicas de carregamento. Nesta tese, sao investigados os mecanismos que provocam inducao de corrente persistente em lacos supercondutores na ausencia de campo externo, e os resultados mostraram que existem limites inferiores e superiores para inducao da corrente persistente, e que o surgimento de hot spots pode prejudicar o carregamento. Sao propostos modelos transitorios para o campo eletrico no laco, que levam em consideracao as variacoes de corrente e a potencia dissipada na fita, que foram validados por uma ferramenta de ajuste nao-linear do software Matlab. Os resultados dos ajustes mostraram boa concordância com os dados experimentais, demonstrando a validade dos modelos. E proposto um novo metodo para medicao da corrente critica em lacos supercondutores e tambem e apresentada uma nova geometria de bobina com lacos que, alem de exigir um sistema de inducao menos robusto, pode facilitar o carregamento na presenca de campo magnetico.
Condition Monitoring of Bearing Faults Using the Stator Current and Shrinkage Methods

Condition monitoring of bearings is an open issue. The use of the stator current to monitor induction motors has been validated as a very advantageous and practical way to detect several types of faults. Nevertheless, for bearing faults, the use of vibrations or sound generally offers better results in the accuracy of the detection, although with some disadvantages related to the sensors used for monitoring. To improve the performance of bearing monitoring, it is proposed to take advantage of more information available in the current spectra, beyond the usually employed, incorporating the amplitude of a significant number of sidebands around the first eleven harmonics, growing exponentially the number of fault signatures. This is especially interesting for inverter-fed motors. But, in turn, this leads to the problem of overfitting when applying a classifier to perform the fault diagnosis. To overcome this problem, and still exploit all the useful information available in the spectra, it is proposed to use shrinkage methods, which have been lately proposed in machine learning to solve the overfitting issue when the problem has many more variables than examples to classify. A case study with a motor is shown to prove the validity of the proposal.
A community perspective on the concept of marine holobionts: current status, challenges, and future directions

Host-microbe interactions play crucial roles in marine ecosystems. However, we still have very little understanding of the mechanisms that govern these relationships, the evolutionary processes that shape them, and their ecological consequences. The holobiont concept is a renewed paradigm in biology that can help to describe and understand these complex systems. It posits that a host and its associated microbiota with which it interacts, form a holobiont, and have to be studied together as a coherent biological and functional unit to understand its biology, ecology, and evolution. Here we discuss critical concepts and opportunities in marine holobiont research and identify key challenges in the field. We highlight the potential economic, sociological, and environmental impacts of the holobiont concept in marine biological, evolutionary, and environmental sciences. Given the connectivity and the unexplored biodiversity specific to marine ecosystems, a deeper understanding of such complex systems requires further technological and conceptual advances, e.g., the development of controlled experimental model systems for holobionts from all major lineages and the modeling of (info)chemical-mediated interactions between organisms. Here we propose that one significant challenge is to bridge cross-disciplinary research on tractable model systems in order to address key ecological and evolutionary questions. This first step is crucial to decipher the main drivers of the dynamics and evolution of holobionts and to account for the holobiont concept in applied areas, such as the conservation, management, and exploitation of marine ecosystems and resources, where practical solutions to predict and mitigate the impact of human activities are more important than ever.
A REVIEW OF BENCHMARKING IN PHOTOGRAMMETRY AND REMOTE SENSING

Abstract. This paper is a preface of the ISPRS/EuroSDR Workshop on the “Evaluation and Benchmarking of Sensors, Systems and Geospatial Data in Photogrammetry and Remote Sensing” that was held in Warsaw University of Technology on 16-17 September 2019. The paper reviews benchmarking in photogrammetry and remote sensing found in the literature relating to geodata. The first part of the paper is a bibliographic analysis based on queries in Scopus and Web of Science databases which shows an increase in research activities based on benchmarking data. In the second part, a review of past and ongoing benchmarking initiatives is presented, providing examples of initiatives within e.g. ISPRS and EuroSDR. The topic of evaluating data, sensors and algorithms with benchmarking activities is interesting as it provides the opportunity to compare, with a unique approach, research results from independent scientists. As hereafter reported, benchmarking has increased in recent years, with many benchmarks being presented in the photogrammetric and remote sensing communities.
Trabalho formal na cadeia de produção de carne bovina

A cadeia de producao de carne bovina no Brasil possui grande representatividade no mercado de trabalho e emprega milhares de pessoas. O produto final atende as demandas interna e externa, e o aumento dos niveis de producao dos ultimos anos tem auxiliado no controle dos indices de preco e da balanca comercial do Pais. Contudo, os conflitos entre os diversos elos da cadeia de producao prejudicam o bom andamento do setor e a qualidade dos produtos para os consumidores finais. Nesse contexto, considerando os muitos autores que apontam para a importância do nivel educacional e da experiencia profissional dos agentes para o bom desempenho da cadeia, o objetivo deste estudo e verificar como ocorrem as bonificacoes salariais na cadeia de producao de carne bovina no Brasil, seccionado em tres subsistemas: de producao de materia-prima, industrializacao e servicos. Os resultados mostram que os incentivos ocorrem nos tres subsistemas, mas com enfase no de distribuicao, sendo o responsavel pelo maior estimulo no acumulo de capital humano e de experiencia profissional. Alem disso, visualizou-se que o subsistema de producao de materia-prima se mostrou o menos interessado no acumulo desses dois atributos, o que pode ser um gargalo para o bom desempenho da cadeia de producao, em virtude de o subsistema de materia-prima ser maior que a soma dos outros dois subsistemas.
Nonintrusive Load Monitoring Based on Complementary Features of Spurious Emissions

In this paper, a novel method that utilizes the fractional correlation-based algorithm and the B-spline curve fitting-based algorithm is proposed to extract the complementary features for detecting the operating states of appliances. The identification of appliance operating states is one of the key parts for nonintrusive load monitoring (NILM). Considering the individual spurious emissions generated because of nonlinear components in each electronic device, the spurious emissions from the power cord can be picked up to solve the problem of data storage. Five types of common household appliances are considered in this study. The fractional correlation-based algorithm and B-spline curve fitting-based algorithm are used to extract two groups of complementary features from the spurious emissions of those five types of appliances. The experimental results show that the feature vectors extracted using the proposed method are obviously distinguishable. In addition, the features extracted show a good long-time stability, which is verified through a five-day experiment. Finally, based on support vector machine (SVM) and Dempster–Shafer (D-S) evidence theory, the identification accuracy reaches 85.5% using a combining classifier incorporated with the features extracted from the proposed methods.
Reducing the Impact of Local Load Variation on the DUT in a Process Detector Using a Supply Controlled Ring Oscillator

The extraction of threshold voltage (<inline-formula> <tex-math notation="LaTeX">$V_{TH}$ </tex-math></inline-formula>) of a transistor using process detector is important for device and process characterization. This paper proposes a fully digital on-chip <inline-formula> <tex-math notation="LaTeX">$V_{TH}$ </tex-math></inline-formula> detector using a supply controlled ring oscillator (RO) to extract local random variation of <inline-formula> <tex-math notation="LaTeX">$V_{TH}$ </tex-math></inline-formula>. As a single RO is employed to extract <inline-formula> <tex-math notation="LaTeX">$V_{TH}$ </tex-math></inline-formula> variation from an array of independently selectable device under tests (DUTs), the local load variation observed by each DUT is almost constant and makes the proposed detector insensitive to local load variation. The supply noise due to the oscillation of RO can be suppressed using a decoupling capacitor. The measurement results of 300 DUTs in a test chip, occupying a silicon area of <inline-formula> <tex-math notation="LaTeX">$44 ~\mu \mathrm {m} \times 126 ~\mu \text{m}$ </tex-math></inline-formula> in 130 nm technology node demonstrates the efficacy of the proposed detector.

Asthma knowledge, experience, beliefs, and self-efficacy of childcare center workers in selected urban and rural countries in Tennessee

Asthma, the leading chronic disease of childhood, affects over five and one-half million children. Children, aged zero months to four years, have experienced the greatest increase in asthma prevalence, with a rise of 160 percent from the early 1980s to 1994. Tennessee's asthma prevalence rate for children is estimated at 7.4 percent. With proper management, a child with asthma can have normal or near-normal lung function. There are over 300,000 children enrolled in childcare centers in Tennessee. Childcare workers must learn proper asthma management to minimize the impacts of asthma on children. The purpose of this study was to evaluate the asthma knowledge, beliefs, experience, and self-efficacy of childcare center workers in selected urban and rural counties in Tennessee. The Health Belief Model was used as the theoretical foundation for this research. The Tennessee Childcare Asthma Survey was created to measure childcare worker perceptions by adapting an existing survey used to analyze parent's knowledge, beliefs, and self-efficacy of asthma. The instrument was reviewed by an expert panel and childcare workers, validated, and pilot tested for reliability. Childcare centers, licensed by the Tennessee Department of Human Services, were identified in selected urban and rural counties. The drop-off method was used to collect the data. Data were analyzed using t-tests, chi-square testing, cross tabulation residual analysis, multivariate tests, analysis of variance, Pearson's correlation, Spearman's Rho, z-tests, and measures of central tendency. The following major conclusions were drawn from this study: (1) center location was associated with childcare workers' self-reported
Unconventional small-scale biogas production with reduced local impact

One of the problems of food waste management is the acceptability of the treatment plants at local level because of the risk of odours. Anaerobic digestion as first step before composting has contrib- uted to solve this problem, but, in the sector, it remains an opposition to large plants. That affects also food waste anaerobic digestion: people’s perception is that the stream coming at the gate of the plant is not theirs. The present paper shows an alternative to the conventional approach. The aim is to reduce the scale of the intervention giving a solution also to small municipalities or to an aggregation of small municipalities. The basic idea is suitable for adaptations depending on the local availability of manure and other plants specialised on wastewater. The integrability of these plants allows reduc- ing the costs for treating secondary streams to be managed, as discussed in the article. The extreme technological scenario is based on an anaerobic digester with unconventional pre-treatment of food waste and energy recovery, on a hydro-thermal carbonisation reactor for manure, on an ammonia separator for product recovery (by stripping), on a CO 2 separator (from off-gases), on a hydro-biochar flusher for opening to land application and on mechanised small-scale composters for small com-munities. The principles of the circular economy are adopted, but the economic balance is affected by the transport costs of the products. The suitability of this approach to medium income countries is discussed too.
Athletic Training and Sports Medicine: An Integrated Approach

Written in cooperation with the American Academy of Orthopaedic Surgeons (AAOS), Athletic Training and Sports Medicine: An Integrated Approach, Fifth Edition is a multi-purpose, multi-course text that emphasizes the post-injury management techniques used by athletic trainers and physicians in management of orthopaedic injuries. This classic text has been re-titled to more accurately reflect the topical coverage of injury management and care. Richly illustrated and full of evidence-based practice, this text describes surgical techniques and their implications on rehabilitation/activity and captures the totality of injury management including: pathology, immediate management, diagnostic imaging, definitive and differential diagnosis, medical management, medications, surgical intervention, post-injury and/or post-surgical management, and rehabilitation. Athletic trainers are well educated on how to evaluate, manage, and rehabilitate athletic injuries. However, no other mainstream textbook describes what is involved with common surgical procedures and how those procedures affect the treatment and rehabilitation process and the eventual return to activity. Athletic Training and Sports Medicine: An Integrated Approach serves as a primary reference to tie it all together.
A parallel FFT‐accelerated layered‐medium integral‐equation solver for electronic packages

A parallel iterative layered‐medium integral‐equation solver is presented for fast and scalable network parameter extraction of electronic packages. The solver, which relies on a 2‐D fast Fourier transform (FFT)‐based algorithm and a sparse preconditioner to reduce computational complexity, is parallelized using three workload decomposition strategies, including a pencil decomposition that increases the scalability of the computationally dominant FFT‐based multiplication stage. A set of increasingly difficult benchmark problems, which require network parameter computations for Ntrace = 1 to 257 package‐scale interconnects, are solved on a petaflop scale computer to quantify the solver's accuracy, efficiency, and scalability. The total serialized computation time is observed to scale asymptotically as Ntrace2.6logNtrace . For the largest problem, using ~1.14 million unknowns and 1536 processes, the solver requires a wall‐clock time of ~0.05 s per iteration, ~1 minute per excitation, ~9 h per frequency, and ~424 hours to extract the 514‐port network parameters at 40 sample frequencies between 1 to 40 GHz.

Phase Stability and Thermal Equation of State of Iron Carbide Fe3C to 245 GPa

We conducted shock wave experiments on iron carbide Fe3C up to a Hugoniot pressure of 245 GPa. The correlation between the particle velocity (up) and shock wave velocity (us) can be fitted into a linear relationship, us = 4.627(±0.073) + 1.614(±0.028) up. The density‐pressure relationship is consistent with a single‐phase compression without decomposition. The inference is further supported by the comparison of the observed Hugoniot density with the calculated Hugoniot curves of possible decomposition products. The new Hugoniot data combined with the reported 300‐K isothermal compression data yielded a Grüneisen parameter of γ = 2.23(7.982/ρ)0.29. The thermal equation of state of Fe3C is further used to calculate the density profile of Fe3C along the Earth's adiabatic geotherm. The density of Fe3C was found to be too low (by ~5%) to match the observed density in the Earth's inner core, and Fe3C is unlikely a dominant component of the inner core.
