astro-ph/0312059 Proekt Skysoft (The Skysoft Project)
Authors: C. Baffa, E. Giani, A. Checcucci
Comments: 4 pages

Proekt Skysoft - internet kollekciya astronomicheskogo programmnogo obespecheniya razlichnogo urovnya ot prostogo professional'nogo i polu professional'nogo do lyubitel'skogo (no poslednego malo). Avtory nadeyutsya, chto ot drugih kollekcii astronomicheskogo softa, sushestvuyushih segodnya v seti, eta budet otlichat'sya professional'noi podderzhkoi i orientaciei ne tol'ko na pol'zovatelei, no i na razrabotchikov. V nastoyashee vremya po adresu http://www.skysoft.org dostupny 197 programm.


astro-ph/0312063 AstroCat/CVcat: katalog peremennyh zvezd v ramkah novoi ideologii interaktivnyh astronomicheskih baz dannyh (AstroCat/CVcat: A catalogue on Cataclysmic Variables based on a new framework for online interactive astronomical databases)
Authors: F.Euchner et al.
Comments: 4 pages, 2 figures

Nekotore vremya nazad byla predlozhena koncepciya interaktivnyh astronomicheskih baz dannyh AstroCat. Katalog kataklizmicheskih peremennyh CVcat - pervaya baza dannyh postroennaya po etomu principu.

astro-ph/0312195 Giperatlas: novyi standart hraneniya i peredachi izobrazhenii (Hyperatlas: A New Framework for Image Federation)
Authors: R. D. Williams et al.
Comments: Published in ADASS XIII proceedings

Predlagaetsya novyi otkrytyi standart hraneniya obshedostupnyh izobrazhenii zvezdnogo neba. Kazhdoe izobrazhenie rassmatrivaetsya kak proekciya uchastka sfery na ploskost', iz takih perekryvayushihsya uchastkov (fasetov) stroyatsya polnye atlasy i krupnomasshtabnye izobrazheniya. Standart orientirovan na massovoe hranenie izobrazhenii i na ispol'zovanie ego v virtual'nyh observatoriyah.

cs.CV/0308038 Analiz astronomicheskih izobrazheniya dlya bol'shih "nablyudatel'nyh mashin" (Image Analysis in Astronomy for very large vision machine)
Authors: G.Iovane
Comments: 3 pages, 9 figures

Segodnya na rannei stadii razrabotki nahodyatsya proekty bol'shih nablyudatel'nyh kompleksov (teleskop + priemnik + komp'yuter + software) dlya obnaruzheniya ekzoplanet po variaciyam bleska ih svetil iz-za prohozhdenii po disku. Odnoi iz problem podobnyh ustanovok yavlyaetsya ogromnyi potok dannyh: dlya togo chtoby chasto obnaruzhivat' planety nado odnovremenno sledit' za bol'shim chislom zvezd s vysokim vremennym razresheniem (chtoby ne propustit' moment izmeneniya bleska) i s vysokoi tochnost'yu (0.01 zvezdnoi velichiny i luchshe) Sohranit' etot potok informacii nevozmozhno, poetomu ego obrabatyvayut v real'nom vremeni s ispol'zovaniem prostoi triggernoi shemy s dvumya urovnyami. Dlya obrabotki dannyh s bol'shih PZS (16000h16000 elementov), kotorye planiruetsya stavit' na podobnyi teleskop, budet dostatochno seti ne bolee chem iz 256 standartnyh rabochih stancii!

(Po-vidimomu, dannaya stat'ya napisana na osnove doklada-prezentacii: ochen' szhatyi tekst bez detalei i bol'shoe chislo krasochnyh kartinok.)

astro-ph/0308047 Centr dannyh INTEGRALa (ISDC) (The INTEGRAL Science Data Centre (ISDC))
Authors: T.J.-L. Courvoisier et al.
Comments: 5 pages, 2 figures. Accepted for publication in A&AL (INTEGRAL issue)

Sputnik INTEGRAL ochen' vazhen dlya evropeiskoi astronomii. Krome togo, on ochen' vazhen dlya Rossii. Pervym rezul'tatam etoi kosmicheskoi observatorii budet posvyashen special'nyi nomer Astronomy & Astrophysics. V etoi stat'e rasskazyvaetsya o edinom centre dannyh sputnika. Observatoriya yavlyaetsya mnogofunkcional'noi, ispoveduyushei politiku otkrytyh dannyh (spustya nekotoroe vremya posle nablyudenii vse materialy stanovyatsya dostupnymi mirovomu soobshestvu). Vse eto trebuet bystrogo i kachestvennogo predostavleniya dannyh vsem zhelayushim. Imenno etoi rabotoi zanimaetsya centr dannyh.

cs.DB/0307032 Upravlenie dannymi i kopanie v astrofizicheskih bazah dannyh (Data Management and Mining in Astrophysical Databases)
Authors: M. Frailis, A. De Angelis, V. Roberto
Comments: 10 pages, Latex, S. Ciprini, A. De Angelis, P. Lubrano and O. Mansutti (eds.): Proc. of `Science with the New Generation of High Energy Gamma-ray Experiments'' (Perugia, Italy, May 2003). Forum, Udine 2003, p. 157

Astronomicheskih ob'ektov mnogo, a potomu mnogo dannyh. Rabotat' s nimi (pover'te!) ochen' tyazhelo. K schast'yu, raznoobraznye sovremennye tehnologii zdes' ochen' pomogayut. V stat'e rech' idet kak raz ob etom. Krome astronomov stat'ya mozhet byt' ochen' interesna vsem tem, kto zanimaetsya rabotoi s bol'shimi massivami dannyh.

Authors: P. Boinee, A. De Angelis, E. Milotti
Comments: 9 Pages, corrected authors name format Subj-class: Neural and Evolutionary Computing; Artificial Intelligence

Soderzhanie stat'i ochen' tochno sootvetstvuet ee nazvaniyu. A v kachestve primera rassmotrena sistema avtomaticheskoi klassifikacii gamma-vspleskov.


cond-mat/0307346 Neiroinformatika: Kto my, kuda my idem, kak izmerit' nash put'? (Neuroinformatics: What are us, where are we going, how to measure our way?)
Authors: A.N. Gorban
Comments: 9 pages,4 figures, The lecture was given at the USA-NIS Neurocomputing opportunities workshop, Washington DC, July 1999 (Associated with IJCNN'99)

Neironnye seti nahodyat mnozhestvo razlichnyh primenenii, v tom chisle i v obrabotke astronomicheskih dannyh (my neskol'ko raz pisali ob etom). Eta rabota yavlyaetsya dovol'no populyarnym obzorom po neiroinformatike, gde opisyvayutsya osnovnye principy, a takzhe reshennye i nereshennye problemy.

Sm. takzhe stat'yu "Automatic Classification using Self-Organising Neural Networks in Astrophysical Experiments", gde rassmatrivaetsya primenenie neironnyh setei v astronomii.
