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
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

Composition, seasonal occurrences and habitat use of bird assemblages in wet forests on the Central Plateau ofTasmania
No full textBird communities in montane wet forest at three sites (altitudes 700,750 and 880 m) on the Central Plateau of Tasmania were surveyed over a 12-month period between December 1991 and November 1992. Monthly transect counts were carried out at each site. Snowfalls are common at all three sites during winter and snow can remain at the highest site for several weeks. Bird communities at the study sites showed significant differences in densities and seasonal patterns even though species composition was similar. These differences were influenced by the variation in habitats and the environments at the sites. Butlers Road, the lowest site with the mildest winters and greatest proportion of drier habitat, had the highest bird densities, while D'Arcys Bluff, at the highest altitude, had the lowest. The degree of seasonal changes of birds was similar to mainland montane wet forests, with over half the species moving either locally or to the mainland. However, there was variation in seasonal occurrences between the study sites, with proportionally more species moving from the highest site during the winter, Within the study sites, the wet forest habitats with a diverse shrub and/or fern understorey supported higher bird populations than did mixed forest and damp forest. Species richness is lower at these sites compared with equivalent montane forests on mainland southeastern Australia
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
On conformally invariant equations on Rn
No full textAbstract. In this paper we provide a complete characterization of fully nonlinear conformally invariant differential operators of any integer order on Rn, which extends the result proved for operators of the second order by A. Li and the first named author in [38]. In particular we prove existence and uniqueness of a family of tensors (suitably invariant under Möbius transformations) which are the basic building blocks that appear in the definition of all conformally invariant differential operators on Rn. We also explicitly compute the tensors that are related to operators of order up to four. 1. Introduction an
Bounds on the measurable chromatic number of Rn
No full textAbstractWe develop a method of estimating the (upper) density of a set in Rn or Sn for which the distance between any pair of points is not in a prescribed set. This is a generalisation of a planar principle of the first author. It improves the best known results for small values of n⩾3. It also improves the known lower bounds on the measurable chromatic number of Rn for small n⩾4
