Iron/Titanium oxide nanoparticles with initial molar ratio Fe/(Fe+Ti) = 0.05 (low loading of Fe in TiO2) and Fe/(Fe+Ti) = 0.15 (high loading of Fe in TiO2) were synthesized by a modified sol-gel procedure using Ti(IV)-isopropoxide, FeSO4 ∙ 7H2O and poly(ethylene glycol) (PEG) as starting material. The amount of doped iron strongly affected structural properties as well as the degree of dispersion of iron in the Fe-Ti-O system. The highly-doped sample contained poorly crystallized hydrated iron(III)-sulphates or basic iron(III)-sulphates in a considerable amount. The lowly-doped Fe-TiO2 sample contained about 22 wt % of brookite that had taken up iron virtually in the same proportion as anatase. Contrary to quasi-homogeneous distributions of iron in the lowly-doped Fe-TiO2 sample, the uptake of iron in the highly-doped Fe-TiO2 sample heated at 500 °C is significant, but anatase is free from iron, thus suggesting a heterogeneous distribution of iron. The photocatalytic activity of the highly-doped Fe-TiO2 sample was better than that of the lowly-doped Fe-TiO2 sample, but still below the photoactivity of Degussa P25 reference photocatalyst.

Zadovoljstvo stanovanjem jedan je od pokazatelja kvalitete života koji utječe na sve aspekte životnih dimenzija, od fizičkih, ekonomskih, socijalnih do psiholoških. Zbog svoje kompleksnosti, stanovanje se smatra interdisciplinarnim područjem istraživanja, pa različite struke primjenjuju različite pristupe, koncepte, modele i mjere. Da bi neko istraživanje o stanovanju moglo biti sveobuhvatno, nužno je dati teorijski okvir u njegovu proučavanju. U velikom broju znanstvenih radova, istraživanja i projekata, teorije stanovanja često nisu objašnjene potpuno.

Accessibility of urban green spaces (UGS) is an integral element of satisfying quality of life. Due to rapid urbanization, the studies about UGS are becoming one of the key elements of urban planning. Functional network transport system and optimal spatial distribution of UGS are preconditions for maintaining the environmental balance of the urban landscape. Accessibility analysis of UGS in the settlement of Zadar was conducted as a part of the Urban Green Belts Project (UGB). Development of spatial database was the first step in generating UGS accessibility indicator. Data were collected using the supervised classification method of multispectral LANDSAT images and manual vectorization of high-resolution digital orthophoto (DOP). An analysis of UGS accessibility according to Accessible Natural Greenspace Standard (ANGst) was conducted. Accessibility indicator was generated based on seven objective measures which include the UGS per capita and accessibility of six UGS functional levels. The UGS accessibility indicator was compared with subjective measures that have been obtained by field survey of 718 respondents within 41 statistical units. The collected data reflected an individual assessment and subjective evaluation of UGS accessibility. This study illustrated the importance of using objective and subjective measures in the process of understanding UGS accessibility. It may be concluded that while evaluating accessibility, the residents emphasize the immediate residential environment, neglecting the UGS of higher functional levels. Furthermore, that large amounts of UGS within a city (114 m² per capita) do not necessarily generate a similar satisfaction with their accessibility. The output results may serve as guidelines for the further development of the functional UGS city network., Dostupnost urbanih zelenih površina (UZP) sastavni je element zadovoljavajuće kvalitete života. Zbog nagle urbanizacije proučavanje zelenih površina postaje jedan od ključnih elemenata urbanističkog planiranja. Funkcionalna mreža prometnog sustava i optimalan prostorni raspored UZP-a preduvjeti su za održavanje ekološke ravnoteže urbanog krajolika. Analiza dostupnosti UZP-a u naselju Zadar izvršena je u sklopu projekta Urban Green Belts Project (UGB). Analizi je prethodila izrada prostorno-orijentirane baze UZP-a. Podaci su prikupljeni metodom nadzirane klasifikacije multispektralnih LANDSAT snimaka i metodom ručne vektorizacije DOF snimaka. U prvoj fazi istraživanja izvršena je analiza dostupnosti UZP-a prema ANG standardu. Indikator dostupnosti generiran je na temelju sedam objektivnih mjera koji uključuju površinu UZP-a po stanovniku te dostupnost šest funkcionalnih razina UZP-a. Izvedeni indikator dostupnosti uspoređen je sa subjektivnim mjerama koje su izvedene anketnim ispitivanjem 718 ispitanika unutar 41 statističkog kruga. Prikupljeni podaci reflektiraju individualnu procjenu te zadovoljstvo dostupnošću UZP-om. Ovo istraživanje istaknulo je važnost korištenja objektivnih i subjektivnih mjera u procesu razumijevanja dostupnosti UZP-a. Rezultati su pokazali da prilikom vrednovanja dostupnosti stanovnici naglasak stavljaju na uže stambeno okruženje, zanemarujući time više funkcionalne razine UZP-a. Nadalje, velike količine UZP-a unutar grada (114 m² po stanovniku) ne moraju generirati slično zadovoljstvo njihovom dostupnošću. Izlazni rezultati mogu služiti kao smjernice za daljnji razvoj grada u kontekstu planiranja funkcionalne mreže UZP-a.

U radu je proveden segment vojno-geografskih analiza (vidljivost i domet) za položaj brda Križ u kontekstu oslobađanja okupiranih dijelova zadarskoga područja za vrijeme Domovinskoga rata. Poseban je naglasak stavljen na taktičku zadaću Jaguar, kojom je 22. veljače 1992. brdo oslobođeno od agresorskih snaga. Osnovu za izvođenje prostornih analiza činio je digitalni model reljefa EU-DEM. Metodologija rada temelji se na primjeni ArcGIS for Desktop ekstenzije Military Analyst, čijom su primjenom izrađeni modeli vidljivosti s brda Križ i Sv. Martin. Radi vizualizacije suvremenih metoda operativne pripreme, primjenom alata Range Dome unutar ekstenzije ArcGlobe, izvedene su 3D kupole dometa onoga oružja koje je neprijatelj imao na raspolaganju. Krajobraz je rekonstruiran primjenom vizualnih tehnika na temelju podataka izvedenih metodom nadzirane klasifikacije multispektralnih LANDSAT snimki iz kolovoza 1992. godine. Specifičnost položaja, geomorfometrijska obilježja te tadašnji izgled širega područja brda Križ, uz izvedene analize vidljivosti, potvrđuju taktičku važnost koju je ta lokacija imala na zadarskom području. Oslobođenjem brda ostvareno je nekoliko ključnih ciljeva koji su pridonijeli stabilizaciji života na širem zadarskom području. Primjena GIS metoda omogućila je izvođenje geoprostornih analiza i vizualizaciju te važne taktičke zadaće u kontekstu oslobađanja okupiranih dijelova, što može povećati razumijevanje same važnosti spomenute taktičke zadaće., In this work, a segment of military-geographic analyses (visibility and range) for the position of Križ Hill in the context of the liberation of occupied parts of the Zadar area during the Homeland War (Croatian War of Independence) was carried out. Special emphasis has been put on tactical task “Jaguar”, which involved the liberation of the Hill from the aggressor’s (Serbian) forces on 2 February 1992. The digital elevation model EU-DEM (Digital Elevation Model over Europe) served as the basis for performing spatial analyses. The work methodology is based on the implementation of the ArcGIS for Desktop, Military Analyst extension, which created visibility models from Križ Hill and St Martin Hill. 3D range domes of weapons available to the enemy were created through visualisation of modern operative preparation methods by implementing the Range Dome tool within the ArcGlobe extension. The landscape was reconstructed by implementing visual techniques based on data exported using the method of controlled classification of multispectral LANDSAT records from August 1992. The specificity of the position, its geomorphologic characteristics, and the appearance of the wider area of the Križ Hill in that period, alongside performed visibility analyses, confirms the tactical importance of that location for the Zadar area. By liberating the Hill, several key goals that contributed to the stabilisation of life in the wider Zadar area were accomplished. Use of GIS methods enabled the performing of geospatial analyses and visualisation of this significant tactical task in the context of the liberation of occupied areas of Croatia, which can increase our understanding of the importance of the mentioned tactical task.

Predmet istraživanja rada je tržišno natjecanje između trgovačkih centara u naselju Zadru. Osnovu istraživanja čine prostorni podatci prikupljeni različitim metodama i tehnikama, analizirani primjenom alata geografskoinformacijskog sustava (GIS) uz uvažavanje specifičnih tržišnih zakona. Prema kategorizaciji trgovačkih centara, definirano je šire tržišno područje unutar kojeg je analizirano tržišno natjecanje između trgovačkih centara. Izvođenjem demografskog rastera definirana je gustoća potencijalnih kupaca unutar širega tržišnog područja. Analiza natjecanja uključivala je određivanje tržišnih zona trgovačkih centara, pojavu potencijalnoga tržišnog kanibalizma te definiranje dominantnog centra prema varijabli vjerojatnosti odabira. Tržišne zone određene su na temelju atributa vremena vožnje (min). Metodama terenskog istraživanja, izračunom nelinearne udaljenosti te analizom gustoće trgovačkih centara zaključeno je da se između centara javlja tržišni kanibalizam. U svrhu predviđanja tržišne dominacije, primjenom Huffova modela, izračunate su srednje vrijednosti odabira centara unutar zona preklapanja i širega tržišnog područja. Rezultati Huffova modela potvrđuju tržišnu stvarnost, odnosno da veći broj kupaca unutar zona preklapanja i širega tržišnog područja odabire atraktivniji trgovački centar. Preklapanjem demografskog rastera i Huffova modela kvantificirana je razlika u broju ljudi koji posjećuju atraktivniji trgovački centar., The object of the research is market competition between the shopping centres in the settlement of Zadar. The research is based on the spatial data collected by using various methods and techniques, which were analysed by applying the tools of geographic information system (GIS) with respect to specific laws of market economy. A categorization of shopping centres was made in order to define a broad trade area where the competition between the centres was analysed. A demographic raster was used to define the density of potential consumers within a broad market area. The competition analysis included the determination of the centres’ market zones, the occurrence of potential market cannibalism and the definition of the dominant shopping centre according to a variable of choice probability. The market zones were determined based on the attribute of duration of drive (min). On-site research, calculation of non-linear distance and the analysis of shopping centres’ density, led to a conclusion that market cannibalism occurs between the centres. For the purpose of predicting market dominance, Huff model was used to calculate average values of preference of centres within the zones of overlapping and the broad trade area. The results of Huff model confirm the market reality that a larger number of consumers within the zones of overlapping and the broad trade area prefer a more attractive shopping centre. The difference in number of people that visit a more attractive shopping centre was quantified by overlapping the demographic raster and the Huff model.

Odabir motrilačkih lokacija protupožarnog sustava najčešće uključuje izvođenje analiza vidljivosti. Primjena analitičkih mogućnosti GIS-a, informacijsko-komunikacijskih tehnologija (ICT) te prostorno-orijentiranih podataka pruža osnovu nastanka i djelovanja protupožarnih video sustava.U radu je na temelju indikatora vidljivog zemljišnog pokrova i udjela vidljivog područja u odnosu na ukupnu kopnenu površinu županije, vrednovano šest predloženih lokacija za postavljanje nadzornih kamera unutar Zadarske županije. Vrednovanje je izvršeno analizom preklapanja binarnog modela vidljivosti, tipa zemljišnog pokrova i sloja naselja. Analiza pogodnosti lokacija odrađena je u sklopu projekta „HOLISTIC“ IPA programa jadranske prekogranične suradnje 2007.-2013. Rezultati analize ukazuju na to da dvije od šest predloženih lokacija nisu pogodne za postavljanje nadzornih kamera.Na primjeru dvije potencijalne lokacije nadzornih kamera analiziran je utjecaj pogreške DMR-a na model vidljivosti. Prvi put je na specifičnom primjeru u RH kvantificirana razlika između vjerojatnog algoritma i standardne binarne metode određivanja vidljivosti. Iz rezultata se može zaključiti da pouzdanost modela vidljivosti, odnosno razlika između testiranih algoritama, ovisi o geomorfometrijskim obilježjima terena na kojem se analiza odvija., Selection of observation sites for fire protection system usually includes a performance of viewshed analysis. Application of GIS analytical capabilities, information and communications technology (ICT) and spatially-oriented data provides the basis of the fire protection system.In this research, six proposed locations for set up of surveillance cameras within the Zadar County were evaluated according to indicators of visible land cover and the proportion of the visible area relative to the total land area of the Zadar County. The evaluation was performed by analyzing the overlap of the binary viewshed model, type of land cover and layer settlements. Analysis of suitability for proposed location was performed within the project „HOLISTIC“ IPA program of Adriatic Cross-Border Cooperation 2007–2013.Results indicate that two of the six proposed locations are not suitable for set up of surveillance cameras. On the example of two transmitters, the impact of DEM error on the output results (viewshed model) was analyzed. For the first time on the specific example in Croatia, difference between probable algorithm and standard binary method of determining visibility has been quantified (fig 6 and 7). It can be concluded that the reliability of the viewshed model, or the difference between tested algorithms, depends on geomorphometric features of the terrain on which the analysis takes place.

Batimetrijsko istraživanje jezera na Skradinskom buku obuhvaćalo je širok spektar aktivnosti koje su se provodile u nekoliko faza prema standardima Međunarodne hidrografske organizacije. Mjerenja su izvedena integriranim mjernim sustavom koji je uključivao tri glavne sastavnice: jednosnopni dubinomjer Hydrostar 4300 i GPS uređaje Ashtech Promark 500 – bazni (base) i Thales Z-Max – pokretni (rover). Područje premjera obuhvatilo je 8 jezera ukupne površine 5,677 ha. Ukupno su prikupljene 2623 točke. Istraživanje je provedeno u svrhu: izrade batimetrijskih karta, klasifikacije jezerskog dna, upravljanja i zaštite flore i faune, infrastrukture podataka, turizma i ostalog. Osnovni su ciljevi rada: usporediti učinkovitost metoda interpolacije, odrediti najprikladnije interpolatore za izradu rasterskih modela jezera, izračunati površinu i volumen jezera i usporediti razlike u izračunu između rasterskih modela. Točnost metoda interpolacije ispitana je analizom 8 statističkih parametara koji su dobiveni metodom unakrsnog vrednovanja (cross-validation). Osim analize parametara, interpolacijske metode uspoređene su i vizualno, grafičkim prikazom podataka (dvodimenzionalno i trodimenzionalno). Utvrđeno je da je multikvadratna radijalna osnovna (ROF) metoda po svim parametrima najbolja deterministička, a obični kriging najbolja geostatistička metoda interpolacije. Izrađene su prve batimetrijske karte jezera na Skradinskom buku u Republici Hrvatskoj. Prikazani su novi znanstvenometodološki utemeljeni podaci o batimetrijskim značajkama, površini i volumenu jezera., Bathymetric survey of the lake at Skradinski noise has included a wide range of activities that were carried out in several stages according to the standards of the International Hydrographic Organization. The measurements were made integrated measuring system that included three main components: sonar Hydrostar 4300 and GPS devices Ashtech Promark 500 – base (base) and Thales Z-Max – mobile (rover). Area survey included 8 lakes total area of 5.677 ha. Total has collected 2623 points. The survey was conducted for several reasons: making bathymetry map, lake bottom classification, management and protection of flora and fauna, data infrastructure, tourism and others. The main objectives of the work are to compare the efficacy of the method of interpolation, determine the most appropriate interpolator to produce raster models lakes, calculate the area and volume of the lake and to compare the differences in the calculation between raster models. The accuracy of the interpolation method was tested by analysing eight statistical parameters obtained by the method of cross-evaluation (cross-validation). Besides the analysis parameters, interpolation methods were compared and visually, the graphic representation of data (two-dimensional and three-dimensional). It was found that multiquadrics radial basic (ROF) in all parameters best deterministic, and ordinary kriging best geostatistical methods of interpolation. Made first bathymetric map of Lake at Skradinski buk in Croatia. Shown are new scientific and methodological compelling data on bathymetric features, surface and volume of the lake.
