Modeliranje dinamičkih sustava s pomoću stohastičkih konačnih automata
No full textPredstavljen je novi pristup u izučavanju dinamičkih sustava, temeljen na teoriji є-strojeva J. P. Crutchfielda. Zadatak je iznaći model procesa zaključivanjem isključivo na temelju vremenskog niza. Zaokružena je formalna veza između simboličke dinamike i raščlambe vremenskog niza, te razrađena geneza stohastičkih konačnih automata (SFA) iz razreda konačnih automata (FA). Opisan je općeniti algoritam konstrukcije є-strojeva i izvršena njegova specijalizacija za rekonstrukciju SFA. Uveden je pojam statističke složenosti kao kvalitativno nove mjere za strukturnu složenost realnih sustava. Prema načelima objektnog programiranja razvijena je programska podrška koja implementira algoritam gradbe SFA. Prilikom analize vremenskog niza, kao prva razina modela javlja se raščlambeno stablo definirano kao posebna vrsta binarnog stabla. Konstruirani su izvorni algoritmi za prijeredni, poslijeredni i međuredni nerekurzivni prolaz kroz stablo. Algoritam za usporedbu (pod)stabala provjerava njihovu morfološku i vjerojatnosnu strukturu, te predstavlja okosnicu algoritma za pronalaženje jedinstvenih morfova. Jedinstveni morfovi predstavljaju stanja SFA, a uvjetne vjerojatnosti prijelaza definiraju njegova stohastička svojstva. Program je testiran i prezentiran na nizu primjera sustava zadanih pravilnim izrazima. Prikazani su dobiveni modeli SFA i izračunati statistički parametri. Izvršeno je preliminarno istraživanje nelinearnog sustava opisanog logističkom jednadžbom za više parametara te posebno za Misiurewiczev, i kritični parametar početka puta prema kaosu udvostručenjem perioda. Dobiveni rezultati su konzistentni s onima dobivenim od autora teorije. Zbog ostvarene preglednosti prikaza binarnog stabla i dodatnih informacija koje podastire algoritam nalaženja morfova, olakšano je minimiziranje modela, tj. optimiziranje njegove veličine s obzirom na vrijednost vjerojatnosnog parametra.A new approach to the study of dynamical systems, based on J. P. Crutchfields’s theory of є-machines, is presented. The goal is to find a model by inferring solely from a time series. A formal connection between symbolic dynamic and the parsing of the time series is made, and stochastic finite automata (SFA) are derived from the class of finite automata (FA). The general algorithm for construction of є-machines is explained, with emphasize on its specialization to reconstruction of SFA. A notion of statistical complexity is introduced as a qualitatively new measure for structural complexity or realistic systems. Guided by the principles of object-oriented programming, a software platform for the reconstruction of SFA is implemented. A parse tree, defined as a special kind of binary tree, arises as the first level of reconstruction process. Original algorithms implementing preorder, postorder and inorder traverse through the tree structure are devised. An algorithm for comparison of (sub)trees checks their morphological and probabilistic structure, and makes a key role in the process of finding of unique morphs. The latter presents the states of SFA, and the conditional transitional probabilities provide their stochastic properties. The program was tested and presented on a number of example systems. Resulting SFA-based models and corresponding statistical parameters are given. A preliminary investigation of nonlinear system governed by Logistic map is made for several values of its parameter, especially for Misiurewicz and the critical parameter at the first period-doubling onset of chaos. The results obtained are consistent with those of the author of the theory. The clarity of the binary tree interface helps to control the results of the modeling. Additional in-formation obtained from the morph-finding algorithm enables the minimization of the model, i.e. the optimization of its size regarding the probability difference parameter

JACOBUS de VORAGINE: Passional oder Leben der Heiligen, Nűrinberg, Anton Koberger, 1488
No full textAbstractDuring the revision of the Metropolitana Library in Zagreb in 1996, the incunabula titled Passional oder Leben der Heiligen (Legenda aurea = biographies of saints) was rediscovered. Its author was the famous dominican Jacobuse de Voragine and it was printed in 1488 in Nűrnberg by Anton Koberger, a well known German printer.This beautiful, well preserved incunabula contains 258 biographies of saints printed on 385 folios with 245 smaller coloured pictures and 2 larger gold gilded ones. Each picture is a small masterpiece of detail and messages to us from the lives of the depicted saints. The exlibris in the incunabula proves it to belong to the library of Valvasor.ApstraktTijekom revizije Metropolitanske knjižnice (1996. godine) otkrivena je jedna inkunabula s naslovom: Passional oder Leben der Heiligen (odn. Legenda aurea = Životopisi svetaca) čuvenog talijanskog dominikanca Jacobuse de Voragine, tiskana 1488. godine u Nűrnbergu, kod poznatog njemačkog tiskara Antona Kobergera. Ovaj prelijepi primjerak, veoma dobro sačuvan, sadrži 258 životopisa svetaca na 385 folio listova i ima ukupno 245 manjih sličica u boji te 2 veće slike zlatom ukrašene. Svaka slika iznosi na “svjetlo dana” jednu životnu poruku i daruje nam bogatstvo raznolikosti života svetaca te potvrđuje umijeće majstorskog ostvarenja i oživljavanja detalja. Ovim člankom želim istaknuti da je za našu knjižnicu ova inkunabula vrlo vrijedan primjerak, zbog ručno obojenih ilustracija, a ex libris potvrđuje da pripada Valvasorovoj knjižnici

SURADNJA SAZU I METROPOLITANSKE KNJIŽNICE
No full textABSTRACTAuthors emphasize the connection of the Slovene Academy of Sciences and Arts, especially its Janez Vajkard Valvasor Foundation from Ljubljana, and the Metropolitan Library, the library of the Zagreb Archbishopric and commend successful collaboration of these two institutions. Author closely indicate varied correlation and collaboration of the Slovene Academy of Sciences and Arts and the Metropolitan Library. One of them was the exhibition on the occasion of the significant anniversary of printing of the Valvasor’s manuscripts and works that are exclusively kept in the Metropolitan Library. Emphasis is given to the value of the joint Slovene Academy and the Metropolitan Library project Iconotheca Valvasoriana – the facsimile edition of the Valvasor’s graphic collection that is in process of publishing.POVZETEKV Metropolitanski knjižnici že tristo let hranimo knjižno gradivo Valvazorjeve knjižnice in zbirko grafik, ki jo je koncem 17. stoletja lastnik prodal zagrebškemu nadškofu Aleksandru Ignaciju Mikuliću. Slovenski, hrvaški in evropski kulturni javnosti je predstavljena v obliki knjižnega kataloga: “Bibliotheca Valvasoriana” iz leta 1995, v kratkem pa bo izšel še katalog: „Iconotheca Valvasoriana“ (faksimile, 17 zvezkov) iz Valvazorjeve zbirke grafik. V Valvazorjevi knjižnici najdemo veliko zanimivih vsebin, ki jih lahko posamično in primerjalno obravnavamo na različne načine. Lahko bi izbrali grafike in risbe, jih strokovno proučili in primerjali, vendar znanstvene projekte raje prepustimo profesionalcem ali mlajšim generacijam, ki uporabljajo nove medije. Verjamem, da bo projekt „globalizacije“ prispeval boljše rezultate, ljubitelji pisane besede in strokovnjaki pa dovolj potrpežljivosti in znanja pri ohranjevanju starih knjig in umetnin. Možnost preverjanja informacij v katalogih domačih in tujih knjižnic ter dostopnost referenčne literature, bo omogočila boljšo in hitrejšo računalniško obdelavo knjižnega in umetniškega gradiva. Valvazorjevi knjižnici in zbirki grafik v Metropolitani (zakladnici pisane besede) se moramo zahvaliti, da lahko slovenskemu in evropskemu kulturnemu prostoru ponudimo pomembne informacije o začetkih tiskane besede, bakrorezih, knjižnih ilustracijah in zgodovini tiskarstva. Gradivo vsebuje redke primerke največjih evropskih tiskarn in potrjuje sporočilo iz Theatrum Europaeum: “…iz preteklosti se učimo za prihodnost!”APSTRACTOvim člankom želi se naglasiti povezanost Slovenske akademije znanosti in umetnosti (SAZU) - naročito njezine Fundacije Janeza Vajkarda Valvasora iz Ljubljane i Metropolitane - knjižnice Zagrebačke nadbiskupije (MK) te pohvaliti uspješnu suradnju ovih dviju ustanova. U članku je pobliže naznačena raznolika povezanost i suradnja SAZU i Metropolitanske knjižnice: kroz izložbu o značajnoj obljetnici tiskanja Valvasorova djela: Die Ehre des Hertzogthums Crain te ostvarenih projekata – izdanja Valvasorovih rukopisa i djela koja se isključivo čuvaju u MK. Osobito se želi istaknuti vrijednost projekta SAZU i MK – Iconotheca Valvasoriana – faksimil izdanje Valvasorove grafičke zbirke, koji je u tijeku
Effect of fabrication process on physical and mechanical properties of tungsten carbide - cobalt composite: A review
No full textModernizing the madrasa curriculum in Singapore
No full textThe madrasa curriculum in Singapore continues to modernize to keep up with the times. At the beginning of its establishment, the madrasa curriculum in Singapore was focused on learning the Qur'an and Islamic sciences. However, as time progressed, the madrasa curriculum began to undergo changes. This article aims to explain the process of curriculum modernization in Singapore madrasas as a large part of Singapore's national education goals, and what changes have occurred in relation to curriculum design. This research method uses a qualitative approach with a combined research model between library research and field studies. Data and information from the field were collected from Al-Ma'rif Al-Islamiah Madrasa, one of the madrasas in eastern Singapore. The type of research to be carried out is included in the form of descriptive qualitative, which is a form of research that aims to collect and compile data and try to analyze with interpretation or interpretation of these data. Furthermore, in analyzing the data, the author uses two methods, namely the content analysis method (content analysis) and the descriptive analysis method, especially educational analysis. The results showed that modernization in the curriculum in Singapore Madrasas occurred due to several policies set by the Singapore Ministry of Education with the aim that graduates of madrassa students could be useful not only for the Muslim community, but also for the nation. From the madrasa used as data sources, it can be seen that the curriculum changes in Madrasah Al-Ma'rif was only in the learning system and curriculum materials. Al-Ma'rif Al-Islamiah Madrasah maintains ukhrawi (religious) materials as the main curriculum material, and only adds some secular (academic) materials. While the curriculum model of the madrasa still uses the academic subject model with a separated subject curriculum approach.
Abstrak
Kurikulum madrasah di Singapura terus mengalami modernisasi untuk mengikuti perkembangan zaman. Di awal pendiriannya, kurikulum madrasah di Singapura difokuskan untuk mempelajari Al-Qur’an dan ilmu-ilmu Islam. Namun, seiring dengan perkembangan waktu, kurikulum madrasah mulai mengalami perubahan. Artikel ini bertujuan untuk menjelaskan proses modernisasi kurikulum di madrasah Singapura sebagai bagian besar dari tujuan pendidikan nasional Singapura, dan apa saja perubahan-perubahan yang terjadi terkait dengan desain kurikulumnya. Metode penelitian ini menggunakan pendekatan kualitatif dengan model penelitian gabungan antara library research (penelitian kepustakaan) dan studi lapangan. Data dan informasi dari lapangan dikumpulkan dari Madrasah Al-Ma’rif Al-Islamiah, salah satu madrasah yang ada di kawasan timur Singapura. Jenis penelitian yang akan dilakukan termasuk dalam bentuk deskriptif kualitatif, yaitu bentuk penelitian yang bertujuan mengumpulkan dan menyusun data serta mengusahakan dengan analisis secara interpretasi atau penafsiran terhadap data-data tersebut. Selanjutnya dalam menganalisa data, penulis menggunakan dua metode, yaitu metode analisis isi (content analisys) dan metode deskriptif analisis, khususnya analisis kependidikan. Hasilnya didapat bahwa modernisasi dalam kurikulum di madrasah Singapura terjadi karena beberapa kebijakan yang ditetapkan oleh Kementrian Pendidikan Singapura dengan tujuan agar para lulusan siswa madrasah bisa bermanfaat tidak saja untuk komunitas muslim, tapi juga untuk nasional. Dari madrasah yang dijadikan sumber data terlihat bahwa perubahan kurikulum hanya terjadi pada sistem pembelajaran dan materi kurikulumnya, yaitu tetap mempertahankan materi-materi ukhrawi (agama) sebagai materi utama kurikulumnya, dan hanya menambahkan beberapa materi-materi sekular (akademik) saja. Sedangkan model kurikulum madrasah masih tetap menggunakan model subyek akademik dengan pendekatan kurikulum terpisah (separated subject curriculum)

No full textTowards Finer Granularity in Metadata
No full textIn early 2010, the Austrian Academy of Sciences’ ICLTT instituted an experiment in selective metadata creation for a medium-sized collection (<100 million tokens) of digitised periodicals. The project has two main objectives: (a) assigning basic structures to previously digitised texts, so-called divisions in TEI nomenclature, thus creating a set of new digital objects, and (b) the subsequent categorisation of these texts with the purpose of being able to create thematically organised sub-corpora. An additional objective was to have metadata stored as TEI headers. Attempts at streamlining metadata creation are legion, in particular in the library community. Tools to do the job are often incorporated into workflow engines which consist of commercial products (such as docWORKS[e] and C-3) as well as free products such as Goobi, which incorporates the metadata creation tool RusDML, and the Archivists’ Toolkit™. The experimental workflow being tested at the ICLTT is an attempt to capture detailed metadata for a comparatively large collection of digitised periodicals and other collective publications such as yearbooks, readers, commemorative publications, almanacs, and anthologies. While all higher-level digital objects in the corpus were furnished with metadata from the beginning of the digitisation process, the current experiment is designed to enrich this data to more fully describe the contents of the material at hand. To achieve this end, the department’s standard tools were adapted, which had the added benefit of keeping software production costs at a minimum. While in earlier experiments of our group of researchers (metadata creators) created the TEI header for each text division manually, we have been trying to approach the problem by exploiting the contents section of the digitised issues and/or other secondary sources, which has resulted in a tangible acceleration of the process. Together with collecting basic data such as author, title, publication date, and creation date, the project classifies each division with a type of texts and topics, the latter using the standard Dewey Decimal Classification (version 22, German) with supplementary keywords. This paper discusses a number of issues concerning the quality and type of resulting data. It also touches upon the issue of automation and at what points in the process human intervention is indispensible. Particular attention is directed at the software module for creating TEI headers
