On the validity of the local Fourier analysis
Local Fourier analysis (LFA) is a useful tool in predicting the convergence
factors of geometric multigrid methods (GMG). As is well known, on rectangular
domains with periodic boundary conditions this analysis gives the exact
convergence factors of such methods. In this work, using the Fourier method, we
extend these results by proving that such analysis yields the exact convergence
factors for a wider class of problems
Stellar population analysis on local infrared-selected galaxies
To study the stellar population of local infrared galaxies, which contain
star-forming galaxies, composite galaxies, LINERs, and Seyfert 2s. We also want
to find whether infrared luminosity and spectral class have any effects on
their stellar populations. The sample galaxies are selected from the main
galaxy sample of SDSS-DR4 and then cross-correlated with the IRAS-PSCz catalog.
We fit our spectra (stellar absorption lines and continua) using the spectral
synthesis code STARLIGHT on the base of the templates of Simple Stellar
Population and the spectra of star clusters.Among the 4 spectral classes,
LINERs present the oldest stellar populations, and the other 3 sub-samples all
present substantial young and intermediate age populations and very few old
populations. The importance of young populations decreases from star-forming,
composite, Seyfert 2 to LINER. As to different infrared luminosity bins, ULIGs
& LIGs (log(11) present younger populations than
starbursts and normal galaxies. However, the dominant contributors to mass are
old populations in all sample galaxies. The fittings by using the spectra of
star clusters with different ages and metallicities as templates also give
consistent results. The dominated populations in star-forming and composite
galaxies are those with metallicity , while LINERs and Seyfert 2s
are more metal-rich. The normal galaxies are more metal-rich than the ULIGs &
LIGs and starbursts for the star-forming galaxies within different infrared
luminosity bins. Additionally, we also compare some synthesis results with
other parameters obtained from the MPA/JHU catalog.Comment: 13 pages, 11 figures, accepted for publication by A&
Harmonic analysis on local fields and adelic spaces I
We develop a harmonic analysis on objects of some category of
infinite-dimensional filtered vector spaces over a finite field. It includes
two-dimensional local fields and adelic spaces of algebraic surfaces defined
over a finite field. The main result is the theory of the Fourier transform on
these objects and two-dimensional Poisson formulas.Comment: 69 pages; corrected typos and inserted some changes into the last

REPORT on ANALYSIS of REGIONAL BUDGETS 2008-2011: Findings of a Study of Local Budget Management in 20 Kabupatens and Cities Participating in the Kinerja Program
Government budgets—both State budgets (APBNs) and local government budgets (APBDs)—are important instruments used by government to determine national and regional development priorities. Indeed, it could be said that government budgets mirror political decisions taken jointly by the executive and legislative wings of government. Such decisions necessarily have a big impact on community living standards: depending on the extent to which resultant budgetary expenditure brings benefit to people—especially for the poor and women—in the form of better public services. In short, budgets are yardsticks for measuring the extent to which governments govern for the people.
The KiPAD research project was the brainchild of a network of NGOs who then developed the idea and implemented it as a means of monitoring and evaluating local government budget performance. With support from The Asia Foundation (TAF), Seknas FITRA has carried out KiPAD studies since 2009. In that year and again in 2010, the study encompassed 42 kabupatens (districts) and cities in Indonesia and involved 28 civil society networks, including NGOs, other community groups and tertiary level research units.
The research's overall aim has been to assess the extent to which principles of good governance (transparency, participation, accountability and gender equality) are being integrated into local budgetary processes. More specifically, it has aimed to provide feedback to local governments to help them lift their budget management performance across all phases of the budgetary cycle. By looking at this report, local governments will be able to tell to what extent their budgetary processes are in accord with requirements outlined in the study and will hopefully be inspired by innovative practices put in place by other governments. We also hope that the central government will treat the study as a chance to have a fresh look at national policies for improved sub-national budget performance throughout Indonesia. NGOs too should be able to use KiPAD as a resource for their advocacy work, particularly on budgetary issues—especially pro-poor budgeting in areas studied.
This report—coordinated by Seknas FITRA and supported by TAF and USAID‘s Kinerja Program— incorporates findings of research on budget management in 20 kabupatens and cities for the 2011 fiscal year. It focuses on four stages of the budgetary cycle: 1) planning: which involves various local government activities preparatory to the drafting of annual local budgets; 2) discussion: at this point local governments discuss and reach decisions on budgets they have drafted; 3) implementation: this phase sees local governments carrying out approved budget programs in accordance with allocated funding; and 4) public accountability: at this point governments render an account of implemented budget programs and expenditure
On local analysis
We extend to Gaussian distributions a result providing smoothed analysis estimates for condition numbers given as relativized distances to illposedness. We also introduce a notion of local analysis meant to capture the behavior of these condition numbers around a point.Fil: Cucker, Felipe.

On analysis of complex network dynamics – changes in local topology
Social networks created based on data gathered in various computer systems are structures that constantly evolve. The nodes and their connections change because they are influenced by the external to the network events.. In this work we present a new approach to the description and quantification of patterns of complex dynamic social networks illustrated with the data from the Wroclaw University of Technology email dataset. We propose an approach based on discovery of local network connection patterns (in this case triads of nodes) as well as we measure and analyse their transitions during network evolution. We define the Triad Transition Matrix (TTM) containing the probabilities of transitions between triads, after that we show how it can help to discover the dynamic patterns of network evolution. One of the main issues when investigating the dynamical process is the selection of the time window size. Thus, the goal of this paper is also to investigate how the size of time window influences the shape of TTM and how the dynamics of triad number change depending on the window size. We have shown that, however the link stability in the network is low, the dynamic network evolution pattern expressed by the TTMs is relatively stable, and thus forming a background for fine-grained classification of complex networks dynamics. Our results open also vast possibilities of link and structure prediction of dynamic networks. The future research and applications stemming from our approach are also proposed and discussed
