Il Building Information Modelling da metodo a processo. La realizzazione della nuova metro di Doha

La tesi descrive gli aspetti metodologici e processuali sottesi al Building Information Modelling nella realizzazione di un progetto complesso quale la nuova metro di Doha. L\u2019approccio progettuale e costruttivo indagato si basa sulla centralit\ue0 assunta nell\u2019intero processo dal modello informativo, attraverso l\u2019integrazione e il coordinamento tra le diverse discipline coinvolte (architettura, ingegneria e impianti) e mediante la condivisione delle informazioni in esso contenute tra tutti gli attori coinvolti, dall\u2019ideazione alla realizzazione fino alla futura gestione dell\u2019opera

Pselafine Dalmacije u zbirci dr. Eduarda Karamana u Prirodoslovnom muzeju u Splitu, Hrvatska (Coleoptera, Staphylinidae)

Authors describe the contents of Eduard Karaman\u27s (1849 - 1923) collection, kept in Natural History Museum in Split. In the collection of subfamily Pselaphinae, 43 species (241 specimens) of 129 present species are from Dalmatia and mostly collected by E. Karaman himself. All Pselaphinae from Dalmatia revised are by Zora Karaman. Endemic species of Dalmatia and neighbouring areas are Trimium cavivolle, T. hopffgarteni, T. karamani, Tychobythinus cavifrons, Pygoxyon lathridiiforme and Pselaphus salonitanus. Endemic species of the Balkan are: Bryaxis dalmatinus and Tychus cordiger. One new species found by E. Karaman was named after him Trimium karamani.Autori su opisali sadržaj zbirke Eduarda Karamana (1849 - 1923) koja se čuva u Prirodoslovnom muzeju u Splitu. U zbirci potporodice Pselaphinae od 129 vrsta ima 43 vrste (241 primjerak) iz Dalmacije koje je većinom sabrao E. Karaman. Sve Pselaphinae iz Dalmacije revidirala je Zora Karaman. Za Dalmaciju ili susjedna područja endemske su vrste: Trimium cavivolle, T. hopffgarteni, T. karamani, Tychobythinus cavifrons, Pygoxyon lathridiiforme i Pselaphus salonitanus, a za Balkan su endemi: Bryaxis dalmatinus i Tychus cordiger. Jednu je novu vrstu pronašao E. Karaman i ona je prozvana njegovim imenom Trimium karamani

Die neue Gattung, die in dieser Arbeit beschrieben wird, umfasst gegenwärtig 13 Arten, von denen acht neu sind, sowie fünf neue chromatische Formen: procerula spec. nov. (W.); cyprassaeformis (Bischoff) (W); argenteopunctata spec. nov. (W.) eremita spec. nov. (M.) auricoma (Bischoff) (M.) mit der f. allbofimbriata nov. (M.); garuana (Bischoff) (M.,W.) mit den chromatischen Formen lachnomosa f. nov. (M.), fuscifrons f. nov. (M.) leucotaenia f. nov. (W.) und erythrogastra f. nov. (W.); pavesii (Magretti) (M.); aurataeformis (Bischoff) (M.,W.); mpandaana spec. nov. (M.); crassa spec. nov. (W.): pedemontana spec. nov. (M.); concavolabris spec. nov. (M.) und zambiana spec. nov. (M.). Nur bei zwei Arten sind sowohl Männchen (M.) wie Weibchen (W.) bekannt. Die früher beschriebene Taxa, die zur neuen Gattung Dentotilla gehören, waren den Gattungen Trogaspidia und Glossotilla zugerechnet worden. Die Männchen von Dentotilla sind gut gekennzeichnet durch eine Reihe von morphologischen Besonderheiten, vor allem durch einen Zahn auf der hinteren Coxa, die Weibchen durch ein zusätzliches Paar weißer Flecke auf dem hinteren Rand des zweiten Tergites und durch den verschwommenen hinteren Rand des Thorax. Einige Weibchen sind auch durch ein basal verbreitertes zweites Hinterleibssegment und durch seitliche Wülste auf dem zweiten Sternit gekennzeichnet.Nomenklatorische Handlungenargenteopunctata Nonveiller, 1977 (Dentotilla), spec. n.aurataeformis (Bischoff, 1904) (Dentotilla), comb. n. hitherto Trogaspidia aurataeformisauricoma (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia auricomaconcavolabris Nonveiller, 1977 (Dentotilla), spec. n.crassa Nonveiller, 1977 (Dentotilla), spec. n.cyparissaeformis (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia cyparissaeformiseremita Nonveiller, 1977 (Dentotilla), spec. n.garuana (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia garuanampandaana Nonveiller, 1977 (Dentotilla), spec. n.pavesii (Magretti, 1884) (Dentotilla), comb. n. hitherto Mutilla pavesiipedemontana Nonveiller, 1977 (Dentotilla), spec. n.procerula Nonveiller, 1977 (Dentotilla), spec. n.zambiana Nonveiller, 1977 (Dentotilla), spec. n.Dentotilla Nonveiller, 1977 (Mutrillidae), gen. n.The new genus discribed in this paper actually includes 13 species, eight of which are new, as well as five new chromatic forms: procerula spec. nov.

(m) auricoma (Bischoff) (m) with the f. allbofimbriata nov.(m); garuana (Bischoff) (m,f) and the chromatic forms lachnomosa f. nov. (m), fuscifrons f. nov. (m) leucotaenia f. nov.

(m) and zambiana spec. nov. (m). Only for two species both males (m) and females (f) are known. The previously described taxa belonging to the new genus Dentotilla had been included in the genera Trogaspidia and Glossotilla. the males of Dentotilla can easily be distinguished by a series of morphological peculiaritites, especially by the presence of a tooth on the posterior coxa, the females by a pair of supplementary pubescent spots on the posterior marging of the second tergite as well as by the obliteration of the posterior margin of the thorax; some of the females are characterised also by a basally broadened second abdominal segment and by lateral carinae on the second sternite.Nomenclatural Actsargenteopunctata Nonveiller, 1977 (Dentotilla), spec. n.aurataeformis (Bischoff, 1904) (Dentotilla), comb. n. hitherto Trogaspidia aurataeformisauricoma (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia auricomaconcavolabris Nonveiller, 1977 (Dentotilla), spec. n.crassa Nonveiller, 1977 (Dentotilla), spec. n.cyparissaeformis (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia cyparissaeformiseremita Nonveiller, 1977 (Dentotilla), spec. n.garuana (Bischoff, 1920) (Dentotilla), comb. n. hitherto Trogaspidia garuanampandaana Nonveiller, 1977 (Dentotilla), spec. n.pavesii (Magretti, 1884) (Dentotilla), comb. n. hitherto Mutilla pavesiipedemontana Nonveiller, 1977 (Dentotilla), spec. n.procerula Nonveiller, 1977 (Dentotilla), spec. n.zambiana Nonveiller, 1977 (Dentotilla), spec. n.Dentotilla Nonveiller, 1977 (Mutrillidae), gen. n

Application of Fourier series to differential equations

Rad smo zapoceli objašnjavanjem pojma matematičkog reda i uvođenjem Fourierovog red kao alata za aproksimaciju periodičkih funkcija beskonačnom sumom sinusnih i kosinusnih funkcija. Nakon Fourierovih redova objasnili smo diferencijalne jednadžbe. Posebno smo obradili obične, a posebno parcijalne diferencijalne jednadžbe. Na primjerima smo objasnili važnost diferencijalnih jednadžbi u modeliranju fizičkih problema. Na kraju smo pokazali kako koristiti Fourierove redove kao alat pri rješavanju diferencijalnih jednadžbi.We began our work by explaining the concept of mathematical order and introducing the Fourier series as a tool for approximating periodic functions by an infinite sum of sine and cosine functions. After the Fourier series, we explained the differential equations. We have treated ordinary and partial differential equations separately. Using examples we have explained the importance of differential equations in modeling of physical problems. Finally, we showed how to use Fourier series as a tool for solving differential equations

FOREST CALCULATION OF A BAND DAM WITH TWO CHOKING AREAS

Tema ovog rada jest proracun šuma pojasne brane s dva područja gušenja. Filtar je realiziran općom filtarskom sekcijom 2. reda sa 4 operacijska pojačala. Analiza filtra i proračuni izvršeni su u programskom paketu "Matlab". Ovo uključuje proračune prijenosnih funkcija, frekvencijskih i vremenskih karakteristika, polova i nula, grupnog vremena kašnjenja i šuma normiranih i denormiranih prijenosnih funkcija filtara. Tako dobiveni rezultati provjereni su simulacijom u programskom paketu "LTSpice". Nakon toga projektirana je tiskana pločica u programskom paketu "KiCad 6.0", a filtar je fizički realiziran. Na fizičkoj realizaciji filtra snimljene su frekvencijske karakteristike čime je potvrđeno ispravno djelovanje filtra.The topic of this paper is the design of a bandstop filter with two damping regions. The filter is implemented using a second-order general filter section with four operational amplifiers. The analysis of the filter and calculations were performed in the "Matlab" software package. This includes calculations of transfer functions, frequency and time domain characteristics, poles and zeros, group delay, and noise of normalized and denormalized filter transfer functions. The obtained results were verified through simulation using the "LTSpice" software package. Afterward, a printed circuit board was designed using the "KiCad 6.0" software package, and the filter was physically realized. Frequency characteristics were recorded from the physical realization of the filter, confirming its proper operation
