Bolfuncties in Rn: Spherical harmonics in Rn
No full textIn de wiskunde hebben we bij het modelleren van fysische problemen vaak te maken met randwaardeproblemen. Voor een randwaardeprobleem met een cirkel als rand en een L2- functie als randvoorwaarde, kan deze randvoorwaarde beschreven worden door een Fourierreeks. Hierdoor kan zo'n randwaardeprobleem makkelijker opgelost worden. In dit werk wordt het uitdrukken van functies in Fourierreeksen in R2 uitgebreid naar Rn door bolfuncties in Rn te gebruiken. Eerst wordt er een introductie gegeven in bolfuncties in R2 en er wordt een aantal nuttige eigenschappen van deze functies besproken. Vervolgens worden enkele handigheden voor het werken in Rn genoemd en komen de kwadratisch integreerbare functies aan bod. Tot slot zien we dat de eigenschappen van de bolfuncties in R2 nog steeds gelden in Rn en dat elke kwadratisch integreerbare functie op de eenheidssfeer te schrijven is als lineaire combinatie van bolfuncties.Electrical Engineering, Mathematics and Computer ScienceDelft Institute of Applied Mathematic
The mainstream primary classroom as a language-learning environment for children with severe and persistent language impairment - implications of recent language intervention research
No full textMany UK children with severe and persistent language impairment (SLI) attend local mainstream schools. Although this should provide an excellent language-learning environment, opportunities may be limited by difficulties in sustaining time-consuming, child-specific learning activities; restricted co-professional working, and the complex classroom environment. Two language intervention studies in mainstream Scottish primary schools showed children with SLI receiving intervention from speech and language therapists (SLTs) or their assistants made more progress in expressive language than similar children receiving intervention from education staff. Potential reasons for this difference are sought in the amount of tailored language-learning activity undertaken; how actively school staff initiated contact with SLTs; and the language demands of the classroom. Tailored language learning appears to be a differentiating factor. A language support model, reflecting views of teachers and SLTs about encouraging language development for children with SLI within the ecology of the mainstream primary classroom, is also outlined
La bioeconomia come occasione per un nuovo rinascimento industriale del Mezzogiorno
No full textParlare di bioeconomia significa analizzare la dinamica di un fenomeno in continua trasformazione per sua stessa definizione trasversale ai diversi settori produttivi tradizionali, capace di valorizzare l’incontro tra domanda e offerta di innovazione nelle diverse fasi del ciclo produttivo. A questo livello, la bioeconomia incrocia altri elementi essenziali delle trasformazioni oggi presenti nei mercati come l’economia circolare, l’economia sostenibile e la stessa industria 4.0. Questa rivoluzione produttiva può giovarsi di alcune precondizioni favorevoli presenti in tutto il Paese e, questione inedita rispetto al passato più recente, anche nel Mezzogiorno dove negli ultimi anni si sono sviluppati settori, imprese, modelli legati all’economia circolare e alla bioeconomia. Da qui la possibilità esplorata in questo contributo che la bioeconomia e l’economia circolare possano rappresentare per il Meridione, se adeguatamente sostenute, una nuova occasione di sviluppo favorendo l’aggancio del Sud al resto del Paese, e insieme alle economie più avanzate della competizione internazionale
Excited states in the neutron-deficient nuclei Rn-197,Rn-199,Rn-201
No full textExcited states of the extremely neutron-deficient radon isotopes with N = 111, 113, 115 have been studied for the first time in a series of in-beam experiments performed at the Accelerator Laboratory of the University of Jyvaskyla. The reactions used were: Sn-118(Kr-82, 3n)Rn-197, Sn-120(Kr-82, 3n)Rn-199, Sm-150(Cr-52, 3n)Rn-199, and Sn-122(Kr-82, 3n)Rn-201. The gamma rays emitted from excited states in the different isotopes were identified using the recoil-alpha-decay tagging technique. The estimated cross section for the production of Rn-197(m) was 7(3) nb, which is the lowest cross section reported so far for an in-beam study. The energies of the (17/2(+)) levels built on the isomeric (13/2(+)) states in Rn-197,Rn-199,Rn-201 indicate a transition from an anharmonic vibrational structure toward a rotational structure at low spins for these nuclei. However, the transition is not as sharp as predicted by theory.</p
Proposta de implantação de uma gestão ergonômica nos setores de recepção e governança: um estudo de caso em um hotel quatro estrelas em Natal - RN
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnolóigco. Programa de Pós-Graduação em Engenharia de Produção.Esta pesquisa aborda as condições de trabalho, a que estão submetidos os trabalhadores de um hotel 4 estrelas, da Via Costeira, em Natal - RN. O propósito de realizar este estudo de caso, usando uma abordagem ergonômica do trabalho, surge com o objetivo de diagnosticar as situações de inadaptabilidade existentes nas atividades de trabalho e com a finalidade de sugerir a implantação de uma gestão ergonômica e, conseqüentemente, melhorar as condições físicas e organizacionais do trabalho nesse ramo de negócio. Este trabalho discute, ainda, a necessidade de se evoluir nos atuais modelos organizacionais de gerir os recursos humanos e o processo produtivo do trabalho, desenvolvido pelos gestores dos meios de hospedagem de Natal, uma vez que os métodos e os procedimentos de trabalho são componentes que estão, intrinsecamente, ligados à produtividade e à qualidade dos serviços a serem prestados. Nesse sentido, uma gestão com uma visão ergonômica contribuirá, decisivamente, para qualificar as condições laborais no que se refere aos aspectos físicos diagnosticados como postura, cansaço físico, dores nas pernas, nos braços, na coluna e aos aspectos organizacionais como: a falta de uma política de treinamento e de crescimento profissional etc. observados, in loco, e através da aplicação de questionário e check-list durante o desenvolvimento das tarefas laborais, nos postos de trabalho da Recepção e da Governança. A identificação de todas essas situações de riscos para a saúde e relacionamento social do trabalhador serve para que este estudo apresente algumas alternativas que, se implantadas, evitarão vários constrangimentos que ocorrem numa situação de trabalho e, contribuirá para adaptar da melhor forma as condições reais de trabalho às características psicológicas, físicas e sociais dos trabalhadores, além de enaltecer a capacidade produtiva dos recursos humanos, potencializar a qualidade dos serviços e superestimar a produtividade
An improved Pattern Search based algorithm to solve the Dynamic Economic Dispatch problem with valve-point effect
No full textIn this paper, an improved algorithm based on Pattern Search method (PS) to solve the Dynamic Economic Dispatch is proposed. The algorithm maintains the essential unit ramp rate constraint, along with all other necessary constraints, not only for the time horizon of operation (24 h), but it preserves these constraints through the transaction period to the next time horizon (next day) in order to avoid the discontinuity of the power system operation. The Dynamic Economic and Emission Dispatch problem (DEED) is also considered. The load balance constraints, operating limits, valve-point loading and network losses are included in the models of both DED and DEED. The numerical results clarify the significance of the improved algorithm and verify its performance
Approximation and interpolation by large entire cross-sections of second category sets in Rn+1
No full textIn [M.R. Burke, Large entire cross-sections of second category sets in Rn+1Rn+1, Topology Appl. 154 (2007) 215–240], a model was constructed in which for any everywhere second category set A⊆Rn+1A⊆Rn+1 there is an entire function f:Rn→Rf:Rn→R which cuts a large section through A in the sense that {x∈Rn:(x,f(x))∈A}{x∈Rn:(x,f(x))∈A} is everywhere second category in RnRn. Moreover, the function f can be taken so that its derivatives uniformly approximate those of a given CNCN function g in the sense of a theorem of Hoischen. In the theory of the approximation of CNCN functions by entire functions, it is often possible to insist that the entire function interpolates the restriction of the CNCN function to a closed discrete set. In the present paper, we show how to incorporate a closed discrete interpolation set into the above mentioned theorem. When the set being sectioned is sufficiently definable, an absoluteness argument yields a strengthening of the Hoischen theorem in ZFC. We get in particular the following: Suppose g:Rn→Rg:Rn→R is a CNCN function, ε:Rn→Rε:Rn→R is a positive continuous function, T⊆RnT⊆Rn is a closed discrete set, and G⊆Rn+1G⊆Rn+1 is a dense GδGδ set. Let A⊆RnA⊆Rn be a countable dense set disjoint from T and for each x∈Ax∈A, let Bx⊆RBx⊆R be a countable dense set. Then there is a function f:Rn→Rf:Rn→R which is the restriction of an entire function Cn→CCn→C such that the following properties hold. (a) For all multi-indices α of order at most N and all x∈Rnx∈Rn, |(Dαf)(x)−(Dαg)(x)|<ε(x)|(Dαf)(x)−(Dαg)(x)|<ε(x), and moreover (Dαf)(x)=(Dαg)(x)(Dαf)(x)=(Dαg)(x) when x∈Tx∈T. (b) For each x∈Ax∈A, f(x)∈Bxf(x)∈Bx. (c) {x∈Rn:(x,f(x))∈G}{x∈Rn:(x,f(x))∈G} is a dense GδGδ set in RnRn
Soil radon (Rn-222) monitoring in a forest site in Fukushima, Japan
No full textSoil radon (Rn-222) has been monitored since August 2013 at three different soil depths on a campus forest of Fukushima University in Japan, where a large amount of fallout nuclides were released by the accident of Fukushima Daiichi Nuclear Power Plant in March 2011. The primary purpose of this study is to evaluate Rn-222 activity level, variability and factors controlling Rn-222 concentration in soil air using data obtained from August to December 2013. Time series of Rn-222 activity concentration showed depth-dependent variability with an equilibrium value (Rn-222(eq)) during this observation period; 7.5, 14 and 23 kBq m(-3) at 0.3, 0.6 and 1.0 m in depth, respectively. Two typhoons passing over the site had a great influence on soil radon level, which was practically used for evaluating effective diffusion coefficient of Rn-222. Transport mechanism of Rn-222 in soil air was considered to be diffusion-controlled with data sets on changing Rn-222 concentration with time in selected cases that showed decreasing (or increasing) Rn-222 concentration with time at every depth. Important factors affecting soil Rn-222 variability are meteorological parameters, low-pressure front passing over the site, and subsequent precipitation. Time lags of decreasing Rn-222 concentration at different depths after rain indicate a certain relationship of Rn-222 level with moving water (and water vapor) in soil. The findings obtained in this study are important to evaluate the fate of fallout nuclides (radiocesium) in contaminated forest sites using soil radon as a tracer of moving soil air
