V magistrski nalogi je obravnavano področje vključevanja javnosti v postopek izdelave državnih prostorskih načrtov. V prvem teoretičnem delu so po poglavjih obdelana družbeni in zakonski okvir vključevanja javnosti v postopek izdelave državnih prostorskih načrtov, sledi splošno poglavje o komuniciranju, ki je pri vključevanju javnosti bistvenega pomena. V metodološkem delu je predstavljen pristop, ki preko opazovanja z udeležbo in analize posameznih primerov iz prakse izlušči okvirni model vključevanja javnosti, ki je podrobno predstavljen od pobude do sprejema državnega prostorskega načrta. Na koncu pa so podana ključna načela vključevanja javnosti, ki jih je treba upoštevati pri vsaki pripravi državnega prostorskega načrta. The master thesis examines the field of public participation in the process of creation of the national spatial plans. The first theoretical parts include chapters which examine social and legal framework of involvement of the public in the process of creation of national spatial plans. They are followed by a general chapter on communication, whic is an essential part for the integration of the public. The methodological part includes the presentation of the approach which through participant observation and analysis of individual cases extracts the framework model of integrating the public in practice. The model is presented from the initiative to the acceptance phase of the national spatial plan. At the end, the key principles of involving the public that should be taken into account while preparing each national spatial plan, are presented.

Magistrsko delo raziskuje preobrazbo javnega mestnega prostora s trajnostnim mestnim prometnim načrtovanjem na primeru odprtih javnih prostorov v širšem središču Ljubljane. Pod pojmom preobrazba razumemo povezanost urejenosti odprtega javnega prostora v mestu in obsega trajnostne mobilnosti, saj izhajamo iz izhodišča, da se dobro urejen odprti javni prostor preobrazi v smislu rabe in uporabe trajnostnih načinov mobilnosti oz. se pogosteje uporabljajo nemotorizirani načini mobilnosti in zadrževanje ljudi v prostoru. Magistrsko delo je sestavljeno iz dveh tematskih delov. Prvega dela smo se lotili teoretično in podrobneje predstavili pomen odprtega javnega prostora za mesto. Prav tako smo se teoretično lotili druge spremenljivke v nalogi, in sicer trajnostne mobilnosti ter njune medsebojne povezanosti. Drugi del vsebuje analizo urejenosti in prometne ureditve izbranih primerov odprtih javnih prostorov v Ljubljani. S pomočjo literature smo izbrali kazalnike za določanje urejenosti odprtih javnih prostorov, na podlagi katerih smo izpeljali merila za določitev stopnje urejenosti odprtega javnega prostora (neurejen, srednje urejen ali dobro urejen). Izbrali smo primere dobro in srednje urejenih odprtih javnih prostorov v Ljubljani in v anketni raziskavi s pomočjo potencialnih uporabnikov teh prostorov ugotavljali predvsem obseg in spremembo obsega trajnostne mobilnosti v Ljubljani glede na oceno urejenosti odprtega javnega prostora s strani uporabnikov in glede na pomen urejenosti odprtega javnega prostora za uporabnike. Ob izhodišču, da dobro urejen odprti javni prostor v mestu spodbuja trajnostne nemotorizirane načine mobilnosti in pogostejši obisk/uporabo odprtega javnega prostora, smo postavili tri hipoteze, pravilnost katerih smo preverjali s statističnima testoma ANOVA in Kullbackov test povezanosti. Prvi dve hipotezi se nanašata na odvisnost pogostosti izbire nemotoriziranega načina mobilnosti od pomena urejenosti odprtega javnega prostora za uporabnike in od ocene urejenosti odprtega javnega prostora s strani uporabnikov. S pomočjo statističnega testa ANOVA sta bili hipotezi delno potrjeni. Tretja hipoteza se nanaša na zadovoljstvo uporabnikov odprtih javnih prostorov z zaprtjem mestnega jedra v Ljubljani za avtomobilski promet (kot ena izmed ureditev odprtega javnega prostora) in vpliv le-tega na pogostost njihovega obiska. S pomočjo Kullbackovega testa smo hipotezo o povezanosti v celoti potrdili. The master's thesis explores the transformation of urban public space by using the sustainable urban transport planning on the subject of open public spaces in the wider centre of Ljubljana. Under the term »transformation« we imply the connection between spatial management of open public space in the town and the scope of sustainable mobility, because our opinion is that a well-managed open public space is to be transformed, i.e. its usage and its use of sustainable ways of mobility. This implies that non-motorised ways of mobility are used more often as well as people spending time in public space more often. The master's thesis comprises of two parts. We dealt with the first part theoretically, we also presented the significance of open public space for the city in depth. We dealt with another variable theoretically, namely with the sustainable mobility and their mutual interconnection. The second part of the thesis contains the analysis of spatial and traffic management of the chosen open public spaces in Ljubljana. With the help of literature we chose indicators for determining the spatial management of open public spaces. That was the base to determine the criteria for grading the spatial management of open public spaces (a non-managed, medium-managed, well-managed space). We chose the cases of well-managed and medium-managed open public spaces in Ljubljana. The questionnaire-based aim of the research, whose database consisted of possible users of such public spaces was to find out the scope and scope-change of sustainable mobility in Ljubljana, related to users' evaluation of spatial management of open public space and also related to the significance of spatial management of open public space for the users. With the view that the well-managed open public space in the city encourages the use of sustainable non-motorised ways of mobility and regular usage of open public space, we set out three hypotheses, whose validity we checked with statistical tests ANOVA and the Kullback test for connectedness. The first two hypotheses were concerned with dependency on frequency of chosing non-motorised ways of mobility, i.e. on the spatial management of open public space and on users' grading of spatial management of open public space. The statistical test ANOVA proved the two hypotheses partly. The third hypothesis was concerned with users' contentment of open public spaces in relation to the car-traffic closure for the city centre of Ljubljana (as one of the spatial management activities for open public space), and the closure's impact on users visiting the city centre. The Kullback test entirely confirmed the hypothesis for connectedness.

Celostni pristop k vzgoji in izobraževanju poudarja vrednote trajnostnega razvoja. Naloge učiteljev so ustvariti učne pogoje za kakovostno pedagoško delo. V raziskavi smo vrednotili učinek izkustvenega učenja in terenskega dela na odnos učencev 4.–7. razreda OŠ Naklo do vode ter njihovo znanje o vodi. Zasnovali smo izkustven način pouka v šestih delavnicah. Pouk je trajal štiri šolske ure. Izvajali so ga učenci tretje triade izbirnega predmeta Okoljska vzgoja v vlogi mentorjev učencem drugega vzgojno-izobraževalnega obdobja (druge triade). Odnos do vode in znanje o vodi smo preverili trikrat z anketnim vprašalnikom in testom znanja. S tem smo zbrali podatke o učinkovitosti izvedene učne enote in trajnosti pridobljenega znanja. Učenci, vključeni v raziskavo, so se vsebine o vodi pred tem učili s klasičnim transmisijskim poučevanjem, kar je razlog, da ni bilo razlik med učenci različnih starosti pri preverjanju znanja pred poukom. Z izkustvenim učenjem in spoznavanjem raziskovalnega dela v domačem kraju so dosežki pri učenju in znanju boljši. S terenskim delom so učenci bolj motivirani in navdušeni, hkrati pa se povečuje pozitiven odnos do okolja. Učiteljev odnos in navdušenje dodatno motivirata učence za izkustveno učenje in raziskovanje. Pomembno je, da učenci v drugem vzgojno-izobraževalnem obdobju (8–11 let) dobijo čim več izkušenj z aktivnim učenjem, saj so najbolj dovzetni za oblikovanje odnosa in lastnih vrednot, začnejo se zavedati vrednosti naravne in kulturne dediščine domačega kraja ter razvijajo občutljivost za probleme okolja. Rezultati naše raziskave dajejo učiteljem, ki v pedagoški proces redno vključujejo izkustveno učenje in izvajajo pouk tudi na terenu, močne argumente za uporabo tega. The holistic approach to education and schooling emphasises values of sustainable development. A teacher's task is to enable optimal learning conditions for successful pedagogical process. Pupils, attending Naklo Primary School, aged 9 to 12 were included in the research. The research measures the effects of experiential learning and fieldwork on pupils’ attitude towards water and their knowledge of water. We tried out experiential learning in six workshops. There were four lessons, which lasted for 45 minutes, carried out by pupils aged 12 to 14 attending the optional subject called Environmental Education. They were mentors to the younger pupils. The attitude towards water and knowledge of water was tested three times by using a survey and a test in order to collect data on how effectively the teaching units were carried out and how permanent the acquired knowledge was. Prior to the research the pupils were taught about water through the transmission method of teaching. Consequently, there were no differences in results of tests taken before the lessons by pupils of different ages. Due to using experiential learning and getting to know research work in their hometown area, the results in learning and knowledge are much better. Fieldwork motivates them much more and they are enthusiastic about it and on top of that their attitude towards nature is becoming more positive. Teacher’s attitude and enthusiasm is also of paramount importance and an additional motivator for experiential learning and research. It is crucial that pupils aged 8 to 11 get a lot of experience in active learning as they are still very susceptible to forming their attitude and values and their awareness of how valuable nature and cultural heritage in their hometown area is. They start developing sensibility to environmental issues as well. The results of our research prove to teachers who are already carrying out a lot of experiential learning and fieldwork on regular basis that they are on the right track.

V magistrski nalogi obravnavamo občinske prostorske akte s poudarkom na prostorskih izvedbenih pogojih za posege v prostoru. Tema naloge izhaja iz pogostih kritik udeležencev v postopku pridobivanja gradbenega dovoljenja (zlasti projektantov), da so prostorski akti preveč normirani, preobsežni in neživljenjski. Posledično prihaja do zapletov, tako vsebinskih kot časovnih, pri izdelavi projektov za gradbeno dovoljenje, kar vpliva na negotovost investicij v prostoru. Ker se kot predlog za izboljšavo stanja pogosto predlaga deregulacija, smo v nalogi preverili stanje določil v občinskih prostorskih načrtih in ali deregulacija predstavlja pravo rešitev opredeljenega problema. Z analizo zakonodaje od leta 1875 do danes, primeri iz tuje zakonodaje in teorije, analizo veljavnih občinskih prostorskih načrtov mestnih občin v Sloveniji in anketo med izdelovalci prostorskih aktov, je bilo preverjeno ali so prostorski izvedbeni pogoji res nejasni oz. preveč določeni. Izkazalo se je, da ta trditev drži in da je vzrok za večji delež težav slabo nomotehnično stanje občinskih prostorskih načrtov, katerih določila pretežno priporočajo, namesto da bi eksaktno predpisala poseg, pogosto so tudi preveč splošna (npr. določajo upoštevanje lokalne tradicije oblikovanja) obenem pa ne določijo vsaj osnovnih značilnosti takega oblikovanja. Posledično so možne različne interpretacije določila, kar uporabniku daje občutek, da so določila nejasna. Master thesis deals with municipal planning documents with the emphasis on spatial implementation conditions. Developers and architects (especially designers) are often criticizing municipal regulations in the process of obtaining construction permits, saying they are too normalized, excessive and impractical. Consequently complications arise, both substantive and temporal, in acquiring building permits, which affects the uncertainty of investments in the area. Deregulation is often mentioned as a solution and it is due to this fact that we have analyzed the municipal spatial plans provisions and whether deregulation represents a real solution to the identified problem. By analyzing legislation from the year 1875 until today, examples of foreign law and theory, analysis of existing municipal spatial plans of municipalities in Slovenia and a survey among urban planners, who prepare planning documents, it was examined if the spatial implementation conditions are truly ambiguous and overdetermined. The results show that this statement is true and that many difficulties arise from inadequate legal language as well as from provisions which only suggest instead of regulate or are mostly too general (Eg. they provide consideration of traditional or modern quality facilities and arrangements in the area). At the same time they do not provide criteria to define what is traditional or of good quality. Consequently that causes possible different provision interpretations, which causes the user to think that the provisions are unclear.

Pri distribuciji programske opreme na mednarodnih trgih se pojavi potreba po prilagoditvi programskih produktov, s ˇcimer zagotovimo, da so dostopni in uporabni uporabnikom v razliˇcnih kulturnih in jezikovnih okoljih. Seˇ posebno je ta potreba izrazita pri aplikacijah, ki so namenjene konˇcnim uporabnikom, saj neposredno vpliva na uporabniˇsko izkuˇsnjo. Boljˇsa kot je izkuˇsnja ob uporabi doloˇcenega programa, veˇc uporabnikov se bo odloˇcalo za njeno uporabo. Velik del priprave programskega produkta za mednarodni trg predstavlja proces lokalizacije vmesnika. V prvem delu diplomskega dela bomo predstavili, kako umestiti proces prevajanja v razvoj programske opreme. Na primeru izbranega podjetja bomo predstavili teˇzave, s katerimi se sooˇcajo pri implementaciji procesa. Z zamenjavo orodja za lokalizacijo programske opreme smo poskusili del teh teˇzav odpraviti. Kako je potekal postopek izbire novega orodja, bo predstavljeno v osrednjem delu, ki mu na koncu sledi analiza izbranega orodja ter analiza sprememb na proces prevajanja In order to facilitate the distribution of software on international markets, adaptation of software products is required. This is especially important for end-user applications which need to be accessible and usable in different cultural and linguistic environments. The various steps taken to make software fit for foreign markets are collectively called software localization. The integration of the localization process into the software development cycle is presented in the first part of the thesis. A case study of a prominent Slovenian software company was used to identify the key issues with the implementation of the process and to propose an alternative tool for software localization management. The selection process is presented in the second part of the thesis, followed by an analysis of the selected solution as well as the changes in the localization process in order to evaluate whether the identified shortcomings were mitigated successfully

V diplomski nalogi smo podrobneje predstavili področje razpodvajanja podatkov in implementirali algoritem shranjevanja objektov s privzetim odstranjevanjem podvojenih kosov. V prvem delu naloge smo predstavili shranjevalni sistem kot drevesno urejeno strukturo imenikov in datotek. Opisali smo funkcije shranjevalnega sistema ter preproste načine shranjevanja podatkov na medij. Podrobneje smo pregledali lastnosti porazdeljenega shranjevalnega sistema Ceph, njegove sestavne dele in delovanje. V drugem delu predstavimo metodo razpodvajanja podatkov kot pomembno sestavino sodobnih shranjevalnih sistemov. Pregledali smo tehnike razpodvajanja na centraliziranih in porazdeljenih sistemih. V zadnjem delu naloge smo implementirali primer razpodvajanja skupaj s preprostim sistemom za shranjevanje objektov. S pomočjo opisanih tehnik smo izvedli zaznavanje spremenljivo dolgih podvojenih kosov znotraj objektov in dodali CLI orodja za manipulacijo objektov v shrambi. In our thesis we presented the area of data deduplication and implemented an algorithm for object storage with support for elimination of duplicate chunks within those objects. In the first part we presented storage system as a tree-likestructure of directories and files. We described the features of storage system and simple ways of storing data on a medium. We examined in detail the properties of distributed storage system Ceph, it's components and operation. In the second part we presented deduplicatin as an important feature of modern storage systems. We surveyed deduplication techniques for centralized as well as distributed systems. In the last part we implemented an example of deduplication technique along with a simple object storage system. Using the described techniques we implemented detection of variable-length duplicated chunks within objects and added CLI tools for manipulating objects in the store.

Košarkarski indeks uspešnosti PIR (Performance Index Rating) je formula, ki se pogosto uporablja za ocenjevanje kakovosti košarkarjeve igre. Analiza kvalitete indeksa PIR je bila izvedena na podatkih o klubih in igralcih, ki so sodelovali v ligi ABA zadnjih trinajst sezon. Za pobiranje podatkov iz uradne spletne strani lige ABA je bilo narejeno strgalo dokumentov v obliki HTML. Za lažjo uporabo podatkov v analizi je bila zgrajena podatkovna baza PostgreSQL. V statistični analizi indeksa PIR je bilo preverjeno ali nanj vplivajo košarkarjeva višina, pozicija ali starost ter ali obstaja povezava med uspešnostjo kluba in njegovim povprečnim indeksom PIR. Performance Index Rating (PIR) is a basketball statistical formula that is commonly used for evaluation of basketball players. Quality analysis of index PIR was made on the statistical data of teams and basketball players who played in the ABA league for the last thirteen seasons. A HTML scraper was made for scraping data from the official ABA league website. A PostgreSQL database was built for easier use of data. With statistical analysis of index PIR we explored if basketball player's height, position, or age have influence on his index PIR and if there is a connection between a team's success and it's index PIR.

Napovedovanje prezgodnjega poroda je danes še vedno nezanesljivo, zato številni raziskovalci iščejo metode, ki bi izboljšale njegovo napovedljivost. Nekatere izmed trenutnih raziskav temeljijo na analizi električne aktivnosti maternice, saj vsebuje bogato informacijo o elektrofizioloških lastnostih maternice. Razvili smo algoritme za karakterizacijo, avtomatsko detekcijo in avtomatsko klasifikacijo električnih aktivnosti maternice. Karakterizirali smo jih na osnovi močnostnostnih spektrov, rezultate pa ovrednotili z enosmerno analizo variance ANOVA. Zmogljivost detektorja smo ocenili z uporabo posebnih metrik zmogljivosti. Z optimizacijo detektorja smo dosegli 80,2 % občutljivost in 69,8 % pozitivno napovedljivost. Zmogljivost klasifikatorja smo ocenili z uporabo standardnih metrik zmogljivosti. Najboljše ločevanje med popadki in drugimi električnimi aktivnostmi smo dosegli s klasifikatorjem najbližjega soseda. Dosegli smo 99,1 % občutljivost in 97,3 % specifičnost. Nowadays, prediction of preterm birth is still uncertain and numerous scientists are searching for methods to improve its predictability. Some of the current researches are based on the analysis of electrical activity of uterus which contains rich information about it's electrophysical properties. We developed algorithms for automatic detection, characterization and automatic classification of the electrical activity of uterus. We characterized them on the basis of power spectrums and evaluated the results with the one-way analysis of the variance ANOVA. The efficiency of detector has been assessed by special rate of efficiency. With detector’s optimization we achieved 80.2 % sensitivity and 69.8 % positive predictability. The efficiency of the classifier has been assessed by the standard rate of efficiency. The best distinguishing of uterine activity we achieved with the nearest neighbor classifier. We achieved 99.1 % sensitivity and 97.3 % specificity.

V tem delu se posvetimo avtomatični transkripciji večglasnega petja. Od celotne transkripcije se omejimo na detekcijo tonov. Pripravimo si testno množico večglasnih slovenskih ljudskih pesmi, ki jih pridobimo iz terenskih posnetkov, in zanje zgradimo ročne transkripcije. Nad testno množico poženemo splošni algoritem za polifonično detekcijo tonov. Razvijemo interaktivno vizualizacijo, ki nam ponazori delovanje algoritma in olajša iskanje napak. Rezultatov algoritma ne moremo primerjati, ker je testna množica nova. Algoritem poskusimo izboljšati. Utežitveno funkcijo magnitudnega spektra nadomestimo z linearno, kar prinese slabše rezultate od prvotnih. Poskusimo tudi z dvakratnim beljenjem magnitudnega spektra, ki se obnese nekoliko bolje, a še vedno ne zadovoljivo. Z mehkejšim pristopom k vrednotenju opazimo, da je lahko vzrok težav slabe detekcije tudi problematična testna množica, saj ima precej intonančnih težav. In this work we focus on automatic transcription of polyphonic singing. In particular we do the multiple fundamental frequency (F0) estimation. From the terrain recordings a test set of Slovenian folk songs with polyphonic singing is extracted and manually transcribed. On the test set we try the general algorithm for multiple F0 detection. An interactive visualization of the main parts of the algorithm is made to analyse how it works and try to detect possible issues. As the data set is new we cannot compare the results. Steps are made towards improvements of the algorithm. The magnitude spectrum weighting function is replaced with a simple linear function but results in the degradation of the performance. Then we try to use double spectral whitening of the magnitude spectrum which turns out more promising, but still not satisfactory. A softer evaluation criteria shows that errors in performance might be due to the problematic test set, which has lots of intonation errors.

Zaradi trenutnih gospodarskih razmer je ponudba na nepremičninskem trgu dokaj pestra, vendar pa se prodajalci razmeram ne prilagajajo tudi s cenami. Kupec bi se lažje odločil za nakup nepremičnine, če bi bil informiran o trenutnem gibanju cen primerljivih nepremičnin in vzorcem prodaje, kot na primer za koliko in kdaj prodajalec spusti ceno. Glavni cilj diplomske naloge je bil razviti prototip aplikacije za primerjavo cen nepremičnin na različnih nepremičninskih portalih. Aplikacija lušči nepremičninske oglase s pomočjo predlog iz različnih spletnih virov in jih nato medsebojno povezuje. Ključ za medsebojno povezovanje oglasov je slikovno iskanje. Aplikacija omogoča beleženje zgodovinskih sprememb in kasnejše dodajanje novih predlog. V začetku diplomske naloge je teoretični del, kjer so opisani pojmi in koncepti, ki smo jih srečali in so bistveni za razvoj aplikacije. Osrednji del pa vsebuje opis delovanja in implementacije funkcionalnosti, ki jih izdelan prototip ponuja. As per current economic situation the real estate market is very varied, but the sellers still do not change their prices to accomodate everchanging economic situation. It would be easier for buyer to decide to buy real estate, if he would be informed about current price fluctuation for comparable real estates and sales patterns. Main focus of this thesis is to develop a prototype application for real estate prices comparison on different real estate portals. Application extracts real estate advertisements with the help of templates from different web portals and then links them through utilising reverse image search. Application allows logging changes to advertisements. The thesis begins with theoretical part that describes terminology and concepts, which we encountered while constructing the prototype and are crucial for application development. Main part focues on the description of application operation and implementation of the functionalities that the prototype offers.

Fotostimulator je sistem za proizvajanje definiranih svetlobnih dražljajev pri raziskavah vida. Sistem je sestavljen iz več avtonomnih komponent žarnice, monokromatorja, sivega klina, polarizatorja in komponent, ki so zadolžene za prenos, pretvorbo in interpretacijo zajetih informacij. Diplomska naloga obravnava izdelavo kontrolnega sistema sivega klina. Komponenta, ki nadzoruje intenziteto projicirane svetlobe, je nadalje razdeljena na 5 manjših, med seboj povezanih delov. Intenziteto projicirane svetlobe nastavlja sivi klin, ki je vpet na trak, ki ga poganja koračni motor. Koračni motor z vzbujanjem signalov krmili gonilnik koračnega motorja, ki informacije dobi iz mikrokrmilniške ploščice Arduino. V Arduinu se nahaja logika za nastavitev in nadzor sistema sivega klina. Prvi del diplomske naloge opisuje zgradbo in delovanje fotostimulatorja. V drugem delu se diplomska naloga osredotoča na komponento za kontrolo sivega klina. Photostimulator is a system for the delivery of defined light stimuli for vision research. The system consists of several autonomous components light bulb, monochromator, continuously variable neutral density filter, polarizer and the components, designed for transfer and interpretation of captured data. The first part of the thesis deals with implementation of density filter control system. The component, designed for controlling the intensity of projected light, consists of 5 smaller, coherent parts. The neutral density filter, attached to a linear rail, which is driven by stepper, sets the intensity of projected light. The stepper is controlled by a stepper driver, which gets the data from the Arduino Due microcontroller board. All logic, for setting and controlling the density filter system, is contained within Arduino. The first part of the thesis describes the composition and functioning of system. In the second part, the thesis focuses on the density filter control system.

Današnji hiter ritem življenja nas včasih ovira pri najosnovnejših opravilih. Pogosto smo zato pozabljivi in neprevidni. Z razvojem tehnologije v zadnjih letih je bil omogočen razvoj naprav, ki namesto nas pazijo na našo lastnino in nas opozarjajo, kadar jo pozabimo. V diplomskem delu je opisan razvoj najosnovnejšega sprejemljivega produkta, ki rešuje problem pozabljanja dežnikov. Predstavljen je potek razvoja podjetniške ideje od načrta in raziskav do prvih prototipov. Natančno je opisan končni prototip dežnika s spremljevalno aplikacijo. Naš produkt smo poimenovali Myrella. Modern quick pace of life can sometimes reduce our attnetion towards everyday tasks. Often we become forgetful and unwary. The evolution of technology in recent years enabled development of devices, which supervise our belongings and notify us when we loose something. The thesis describes development of minimum viable product, which solves problem of loosing umbrella. Furthermore, it illustrates progress of business idea, starting with plan and research and ending with first prototypes. The thesis thoroughly describes final prototype of umbrella with accompanying mobile app. Our product was named Myrella.

V diplomski nalogi se bomo dotaknili teme iz računalniško podprtega geometrijskega oblikovanja, katerega namen je zapisati enostavne in tudi bolj zahtevne krivulje v jezik, ki ga računalnik razume. Opisali bomo nekaj osnovnih gradnikov, kot so na primer Bernsteinov polinom, Bezierova krivulja, de Casteljauov algoritem in razcvet. Bolj podrobno bomo opisali in raziskali novo različico razcveta, ki ga imenujemo h-razcvet. Dodani parameter h vpliva na lastnost diagonale osnovnega razcveta in nam omogoča dodatni nadzor nad obliko krivulje. Ogledali si bomo splošne lastnosti h-razcveta, ki jih bomo izpeljali iz osnovnega razcveta. Seveda se bomo lotili tudi razvoja ustreznega algoritma, ki nam bo pomagal pri računanju in oblikovanju krivulje. n the thesis we will consider a topic in computer aided geometric design, which studies curves in a form understandable by computer. We will describe some basic building blocks such as Bernstein basis function, Bezier curve, de Casteljau's algorithm and blossom. Moreover we will be describing a new variant of the blossom, the h-blossom. The h-blossom is introduced by altering diagonal property of the standard blossom which enables us to have more control over the shape of the curve. We will continue the thesis by studying properties of h-blossom. In the end, we will present an algorithm for computing the h-blossom

Ponudba ARM razvojnih ploščic na trgu danes sega od najcenejših 8-bitnih, pa vse do zmogljivejših, za namizno rabo uporabnih računal. Ploščica, ki izstopa po popularnosti je Raspberry Pi. Čeprav lahko zanjo dobimo množico primerov nalog na spletu, večini teh manjkajo priključki na vhodno/izhodne naprave, kar bi olajšalo učenje programiranja vgrajenih sistemov. V okviru diplomskega dela smo razvili primerek vhodno/izhodne razširitvene ploščice. Naknadno smo razvili orodje za lažje programiranje Raspberry Pi, ki je zgrajeno s pomočjo HTML in javascript, kar dodatno olajša programiranje. Okoli teh dveh orodij je napisanih devet nalog, ki segajo od osnovnih vhodno/izhodnih operacij z gumbi in LED diodami, pa do dveh težjih nalog, ki se vrtita okoli PWM (angl. pulse width modulation) izhoda in I2C komunikacije. Wide range of ARM development boards is currently available on the market. Their complexity spans from the simple 8-bit boards to more powerful ones that are also suitable to use as general purpose computers. The most popular ARM board currently available is without any doubt Raspberry Pi. Several study examples that demonstrate its usage are available on the internet. While the input/output devices available in the basic set are very fundamental, these examples are hard to use in the educational purposes directly. We have developed our own input/output extension board with the basic components. We additionally implemented HTML and javascript based development environment for Raspberry Pi programming. 9 educational case study examples, which demonstrate the basic tasks, such as buttons and LED module control, and also more complex tasks, such as PWM (Pulse Width Modulation) output control and I2C communication, were written.

Namen diplomske naloge je najprej nazorno prikazati in razložiti delovanje serijske komunikacije ter pregledati trenutno stanje na tem področju. Drugi cilj diplomske naloge pa je ustvariti generičen gonilnik za serijsko komunikacijo. Ker je potrebno za vsak tip naprave implementirati gonilnik, je smiselno poenostaviti implementacijo in skrajšati čas dela. Za te namene bi radi ustvarili generičen gonilnik za serijsko komunikacijo, ki bi ga s čim manj potrebnega dela lahko pretvorili v gonilnik za poljubno specifično napravo. Te cilje zajema dotična diplomska naloga. Za pravilno implementacijo je potrebno jasno poznavanje same serijske komunikacije in vseh njenih aspektov. Diplomska naloga se ukvarja prav s temi vprašanji in predlaga rešitve ter optimizacije. Del naloge je tako namenjen tudi študiji serijske komunikacije, na podlagi katere temeljijo kasnejše odločitve in argumenti. Diplomska naloga končno poda tudi podlago za nadaljnji razvoj. The goal of the thesis is first to provide a clear explanation of how serial communication works and to review the latest work and progress in the field of serial communication. The second goal of this thesis is to create a generic driver for the purposes of communicating with a device using a serial communication. Since it is required for every type of a device that communicates using a serial port, to implement a dedicated driver, it is logical to simplify this implementation and shorten the working time as much as possible. To achieve this, we would like to develop a generic driver for serial communication, that could be converted to a dedicated driver for any specific device with the least possible effort. These are the ambitions of this particular thesis. For a proper implementation, a clear and wide knowledge of the serial communication functionality and its aspects is required. The thesis oversees these problems and suggests solutions and optimizations.

MapReduce je programski model, namenjen za razvoj skalabilnih paralelnih aplikacij za obdelavo velikih množic podatkov, izvajalno okolje, ki podpira programski model in koordinira izvajanje programov, in implementacija programskega modela in izvajalnega okolja. Cilj diplomskega dela je analizirati MapReduce in ga preizkusiti na dveh primerih priporočilnih sistemov. Cilj smo dosegli, saj smo uspeli realizirati izračun s pomočjo MapReduce na testnih primerih. Najprej smo analizirali programski model in izvajalno okolje ter primerjali tri implementacije MapReduce: Hadoop MapReduce, MongoDB in knjižnico MapReduce-MPI. Ugotovili smo, da je za realizacijo izbranih primerov priporočilnih sistemov najprimernejša implementacija Hadoop MapReduce, saj nudi toleranco za okvare in reproducira podatke, s čimer zagotavlja zanesljivost. Nato smo z uporabo navidezne naprave Cloudera QuickStart VM, ki je gruča Hadoop z enim vozliščem, realizirali izbrana primera priporočilnih sistemov. MapReduce is a programming model for developing scalable parallel applications for processing large data sets, an execution framework that supports the programming model and coordinates the execution of programs and an implementation of the programming model and the execution framework. The goal of the thesis is to analyse MapReduce and to use it on two examples of recommender systems. The goal is achieved by developing the computation with MapReduce successfully. At first the programming model and the execution framework are analysed and three implementations for MapReduce: Hadoop MapReduce, MongoDB and MapReduce-MPI Library are compared. It is discovered that Hadoop MapReduce is the most suitable implementation for developing the selected examples of recommender systems as it provides fault tolerance and data reproduction which ensure reliability. Then the selected examples of recommender systems are developed using Cloudera QuickStart VM which is a one node Hadoop cluster.

Namen diplomskega dela je (pol)avtomatska detekcija skokovitih sprememb v signalu membranske kapacitivnosti celic, in sicer sprememb, ki so posledice eksocitoze ali endocitoze. Ustrezne spremembe v signalu so v preteklosti že detektirali avtomatsko, in sicer s pomočjo matematične analize signala, vendar pa je matematična analiza možna le, če je razmerje med signalom in šumom dovolj veliko. Pri nekaterih tipih celic so amplitude iskanih sprememb tako majhne, da se skoraj popolnoma skrijejo v šumu in preprosta matematična analiza ni več možna. Posledično detekcija ustreznih skokovitih sprememb trenutno poteka ročno. Označenih je bilo že kar nekaj signalov in tako se ponuja možnost olajšanja ročnega pregledovanja s pomočjo strojnega učenja, kar je delo te diplomske naloge. Podatki se na začetku predobdelajo, pri čemer se iz meritve odstranijo kalibracijski pulzi, obsežno šumni predeli meritve ter popravi bazna linija signala, ki predstavlja meritev. Sledi priprava množice podatkov, ki zajema ekstrakcijo učnih primerov, izračun atributov učnih primerov in prevzorčenje učne množice. Zatem se na podlagi učne in testne množice ter različnih metod strojnega učenja predstavijo in primerjajo rezultati klasifikacij novih primerov. The purpose of the thesis is a (semi)automatic detection of rapid changes in the cell membrane capacitance signal, namely changes that are a consequence of exocytosis and endocytosis. Corresponding changes in the signal were previously detected automatically, using mathematical signal analysis. However, mathematical analysis is only possible when the signal-to-noise ratio is sufficiently large. In some cell types the amplitude of the change is so small that it is almost completely hidden in the noise, therefore simple mathematical analysis is no longer possible. Consequently, the detection of the corresponding rapid changes is currently done manually. A number of signals have been labeled and so offers a possibility of facilitating the manual inspection by applying machine learning, which is the work of this thesis. The data is initially pre-processed, where calibration pulses and areas with extensive noise are removed from the measurements and the baseline of the signal representing the measurement is corrected. This is followed by a preparation of the dataset, which includes the extraction of instances, calculation of the attributes of instances and resampling of the training dataset. Then, based on the training set, test set and a variety of machine learning methods, results of the classifications of new cases are presented and compared.

Cilj je narediti dinamični izenačevalnik, torej izenačevalnik, ki ne le statično spreminja frekvenčnega odziva signala, ampak se dinamični razpon posameznih pasov frekvenčnega spektra spreminja glede na razpon le-teh. Povedano drugače, frekvenčni spekter je s filtri razbit na 30 pasov, na vsakem pasu je procesor dinamičnega razpona signala (kompresor, expander, gate). Nastavitve procesorjev so preko grafičnega vmesnika povezane tako, da delovanje in uporaba dinamičnega izenačevalnika spominjata bolj na navaden izenačevalnik kot pa večpasovni procesor dinamičnega signala. Filtri so zasnovani v Matlabu, in sicer tako, da imajo linearno fazo. Enotini odzivi posameznih filtrov so zamaknjeni tako, da imajo sredinski koeficient poravnan, s tem imajo tudi vsi enak fazni zamik. Izenačevalnik in grafični vmesnik sta sprogramirana v programskem jeziku SuperCollider 3.6. The goal is to build a dynamic equalizer, that is an equalizer that not only statically changes the frequency response of a signal, but the dynamic range of individual bands of the frequency spectrum is changed according to the dynamic range of themselves. In other words, the frequency spectrum is broken up with filters into 30 bands, on each there is a dynamic range processor (compressor, expander, gate ). The settings of the processors are connected through a graphic user interface in such a way that its functioning and use resembles more an ordinary equalizer than a multiband dynamic range processor. Filters are designed in Matlab in such a way that they have a linear phase. Impulse responses of individual filters are shifted so that their middle coefficients are aligned. That way they all have the same phase delay. The equalizer and graphic user interface were programmed in SuperCollider 3.6.

Prepoznavanje krožnic na digitalnih slikah je eden od problemov, ki se pojavljajo pri zaznavanju objektov pri procesiranju raznih slik/videoposnetkov. Rešitve se uporablja v mnogih postopkih, kot so analize rentgenskih slik, prepoznavanje krožnih objektov na raznih videoposnetkih, robotski vid, ... Postopek prepoznavanja poteka od pridobitve slike do končnih rezultatov. Med vmesnimi koraki so še priprava slike, črpanje objektov, razne detekcije, visokonivojsko procesiranje in druge. Sama diplomska naloga se osredotoča na algoritme, ki nam omogočajo prepoznavanje krožnic iz podanih točk, večinoma po metodi najmanjših kvadratov. Predstavljenih je nekaj najpogostejših pristopov, med katerimi iščemo najbolj prilagodljive, robustne, hitre in preproste rešitve. Vsi algoritmi so analizirani in stestirani ter podrobno obrazloženi s primeri kode. Na podlagi predstavljenih testov se lahko odločimo za algoritem, ki je najbolj primeren za naš program. Identifying circles on digital images is one of the problems that occur in the perception of objects when processing different images/videos. Solutions are used in many procedures, such as analysis of X-ray images, recognition of circular objects in various videos, robot vision, ... Identification process takes place from image acquisition to final results that we have obtained with the program. The steps in-between are preparing pictures, drawing objects, various object detection, high-level processing and others. This thesis focuses on algorithms that allow us to fit circles based on specified points by using least-squares method. We present some of the most common approaches, among which we are looking for the most flexible, resilient, quick and simple solutions. All algorithms are analysed, tested and explained with code examples. Based on the presented tests we can choose an algorithm that is best suited for our program.

Ob razvoju sistema za avtomatizacijo hiše Assys smo z razširjanjem funkcionalnosti in kompleksnosti dosegli zmogljivostno mejo mikrokrmilnika ATmega328P. V diplomski nalogi smo opisali, katere lastnosti platforme onemogočajo nadaljni razvoj in zakaj je potreben prehod na zmogljiveši mikrokrmilnik. Študijo prehoda smo izvedli na primeru razvojne ploščice STM32F4 Discovery, katera vsebuje zmogljiv mikrokrmilnik iz družine ARM Cortex-M4. Na novi platformi smo implementirali del sistema, ki skrbi za zatemnjevanje in neposredno prikazali koristi zmogljivejše strojne opreme. V študiji smo ugotovili, da je kljub višji ceni in porabi energije mikrokrmilnika ARM, ter dodatnim stroškom ob prehodu zamenjava nujna, upoštevajoč pridobljeno zmogljivost pa tudi upravičena. When developing a system for the home automation Assys we expand the functionality and complexity of the system and with that we achieved the highest capability of microcontroller ATmega328P. In this thesis we described the properties of the platform which prevent the further development and reasons for the need for more capable microcontroller. The study was carried out on the development board STM32F4 Discovery, which contains a powerful microcontroller from the family ARM Cortex-M4. On the new platform, we implemented part of the system which is responsible for dimming and with that we directly demonstrated the benefits of more powerful hardware. In the study, we found out that the replacement of the microcontroller is necessary despite the higher price, power consumption and additional costs during the transition. If we consider the gained performance of the new platform the replacement is justified.
