Pandemia COVID-19 a avut un impact major asupra majorității aspectelor vieții de zi cu zi și acest lucru a dus la o evoluție semnificativ mai rapidă a digitalizării serviciilor medicale. Telemedicina și eSănătatea continuă să ofere soluții pentru atenuarea efectului acestei pandemii, cu scopul de a ajuta pacienții cu coronavirus izolați, precum și persoanele cu afecțiuni cronice. Această lucrare prezintă modul în care pandemia COVID-19 a influențat dezvoltarea sistemelor de monitorizare a stării de sănătate la distanță ca urmare a necesității de a menține o comunicare la distanță între pacient și medicul specialist și de a oferi îngrijiri de calitate. Pentru a demonstra potențialul monitorizării asistenței medicale la distanță, este prezentată Componenta de Monitorizare a Stării de sănătate din sistemul în curs de dezvoltare ROSmartAgeing. Această componentă permite utilizarea senzorilor medicali ce pot colecta și transmite informațiile, printr-o rețea Wi-Fi, la nivelul Fog/Edge, oferind astfel posibilitatea de a alerta specialiștii din domeniul sănătății în cazul unei valori anormale măsurate. Informațiile colectate sunt filtrate și apoi trimise într-o bază de date din Cloud. Beneficiile acestei soluții care permite vizualizarea în timp real a datelor medicale, precum și stocarea, prelucrarea și analiza ulterioară a acestora sunt evidențiate și corelate cu specificitățile induse de pandemia COVID-19.

- Abstract
Postoje problemi koji treba da se rešavaju u nekoliko različitih grana medicine (fizikalna terapija, dermatologija, uopšteno medicina, uključujući stomatologiju, oftalmologiju i otorinolaringologiju i dr). Ako se koristi prednost različitih snopnih tehnika, pojavljuju se prirodno, iste potrebe i u sferi industrije, heritologije, forenzike. Na drugi način pojavljuje se trend da se, objedinjeno, koriste generalno ista rešenja sa modifikacijama u konkretnoj primeni. U radu je poseban akcent posvećen koherentnom elektromagnetnom zračenju, zadacima u vezi prilaza pojedinačnom slučaju, tehničkoj podršci softverske i hardverske prirode i dati su izabrani rezultati pojedinih interakcija ili slučajeva dobijene modulacije u širem smislu. Posmatran je i izabran potreban teoretski prilaz, kao baza za procenu objektivnih uslova, koji mogu da utiču pozitivno / negativno na dati tretman ili dijagnostiku., There are problems that need to be solved for several different branches of medicine (physical therapy, dermatology, medicine in general, including dentistry, ophthalmology and otorhinolaryngology, etc.). If the advantage of various beam techniques is used, the same needs naturally appear in the sphere of industry, heritology, and forensics.In order to obtain target information on the time intervals of therapy, diagnostics and modulation, it must be taken into account that each treatment of individuals is a case for itself, related to the general premises of appropriate dosimetry. That is why in the software there is a large number of tasks for the operation and inclusion of all parameters related to a particular case and for intrusions into the often selfstandardized protocols, which are found in the instructions for the acquisition of new systems, related to Elion techniques. In another way, there is a trend to use, unitedly, generally the same solutions with modifications in specific application. In the paper, a special accent is devoted to coherent electromagnetic radiation, tasks related to the approach to individual cases, technical support of a software and hardware nature, and selected results of individual interactions or cases of received modulation in a broader sense are given. The necessary theoretical approach was observed and selected, as a basis for evaluating objective conditions, which can have a positive / negative effect on a given treatment or diagnosis.

- Abstract
Vlažnost zemljišta je jedan od važnijih parametara u modeliranju i analizi podzemnih voda, poljoprivredi, ekologiji i sl. Monitoring vlažnosti omogućava upravljanje vodnovazdušnim režimom zemljišta čime se obezbjeđuju bolji uslovi za razvoj biljaka i povećanje prinosa. Određivanje vlažnosti zemljišta laboratorijskim metodama zahtijeva značajna materijalna sredstva kao i određeno vrijeme. Razvojem tehnologije danas su dostupni relativno jeftini senzori koji omogućavaju na vrlo efikasan način monitoring vlažnosti na terenu. U ovom radu istražena je mogućnost korišćenja jeftinih senzora za mjerenje vlažnosti na uzorku humusa u laboratorijskim uslovima. Urađena je kalibracija senzora za analizirani uzorak zemljišta korišćenog u eksperimentu na kojem je sprovedeno mjerenje vlažnosti, a rezultati sprovedenog istraživanja provjereni su pomoću Hydrus 1D modela.

- Abstract
Minijaturizacija i pojeftinjenje mikroelektronskih komponenti dovelo je do značajnog širenja bežičnih tehnologija u zadnjih par decenija. Upotreba bežičnih senzorskih mreža u heritologiji vezuje se primarno za evaluaciju stanja objekata: modalnu analizu vibracija, snimanje pukotina u zidovima, detekciju prokišnjavanja i vlage, merenje koncentracije nepoželjnih hemijskih supstanci kao što je ugljen-dioksid, itd. Druge primene uključuju stalni bezbednosni nadzor (zaštitu od nepogoda i provalnika) kao i merenja prilikom sanacije objekata. U ovom pregledu opisane su neke savremene primene bežičnih senzorskih mreža u pomenute svrhe.

- Abstract
A novel and simple electrochemical sensor for the determination of gallic acid is presented. The alumina sample was characterized by X-ray diffraction, FTIR, and particle size distribution analysis. The carbon paste electrode was modified with alumina and used as a sensor. The performances of the sensor were assessed by cyclic voltammetry and square-wave voltammetry techniques. The oxidation of gallic acid on alumina-modified carbon paste electrode was an irreversible diffusion-controlled process. The linear relationship of peak current and concentration was obtained for the concentration range of 1.4 to 115 µM with the limit of detection of 0.8 µM. The sensor’s ability to test gallic aid in real systems was successfully tested in wine samples.

U ovom radu smo se posvetili razvoju mobilne aplikacije s ciljem poticanja društva na povećanje svijesti o okolišu. Kroz proces razvoja, usvojili smo važna znanja o radu sa senzorima, integraciji Google kartama i dohvaćanju vremenskih podataka. Iako aplikacija trenutno nije u potpunosti dovršena, identificirali smo ključne aspekte koji će omogućiti daljnji napredak, kao što je implementacija sustava za prijavu i autentifikaciju korisnika putem Firebase platforme. Vjerujemo da će daljnji razvoj omogućiti aplikaciji da ostvari svoju punu svrhu u poticanju pozitivnih promjena u ponašanju korisnika prema okolišu. Kroz ovaj rad, stekli smo dragocjeno iskustvo u razvoju mobilnih aplikacija i postavili temelje za buduće tehnološke inovacije u području očuvanja okoliša. In this work, we focused on the development of a mobile application aimed at promoting environmental awareness in society. Throughout the development process, we acquired important knowledge of working with sensors, integrating Google Maps, and retrieving weather data. Although the application is not fully completed at this stage, we have identified key aspects that will enable further progress, such as implementing a user login and authentication system through the Firebase platform. We believe that further development will allow the application to fulfill its full purpose in fostering positive behavioral changes among users towards the environment. Through this work, we have gained valuable experience in mobile application development and laid the foundation for future technological innovations in the field of environmental conservation.

Da bi se to izvelo ,potrebno je eksperimentalno odrediti koeficijente koji opisuju odgovor senzora na pobudu.

Cross-axial or transverse sensitivity of an accelerometer can be compensated by digital processing of the output signal. To perform this, it is necessary to determine coefficients that describe a sensor’s response to excitation experimentally. Many procedures advised by standards and scientific papers use expensive equipment which is not available in every laboratory. Therefore, a simple method is proposed, namely a variation of the static tilt test, requiring no other measuring equipment than the sensor itself and a flat surface. Results vary depending on sensor surface and housing quality, but it has been shown that cross sensitivity effects can be reduced from several percent usually associated with commercial threeaxial MEMS accelerometers down to 1% or less. / Кросс-осевая или поперечная чувствительность акселерометра может быть компенсирована цифровой обработкой выходного сигнала. При этом необходимо экспериментально определить коэффициенты реакции датчика на сигнал. Для проведения подобных мероприятий, в соответствии с рекомендациями стандартов и научных статей, применяется достаточно дорогое оборудование, которое не все лаборатории могут себе позволить. В данной связи представлен простой альтернативный метод, разновидность тестирования статичного угла наклона, не требующий никаких измерительных приборов, кроме датчика и плоской поверхности.Несмотря на то, что результаты зачастую зависят от качества поверхности и корпуса датчика, на практике было доказано, что значения поперечной чувствительности при таком методе значительно снижены (в несколько раз), и что типичная поперечная чувствительность трехосевого MЭМС акселерометра с нескольких процентов достигла значения ниже 1%. / Kros- aksijalna, odnosno poprečna osetljivost akcelerometra može biti kompenzovana digitalnim procesiranjem izlaznog signala. Da bi se to izvelo, potrebno je eksperimentalno odrediti koeficijente koji opisuju odgovor senzora na pobudu. Mnoge procedure koje se odnose na to, a koje su preporučene standardima i naučnim člancima, koriste skupu opremu koja nije dostupna u svakoj laboratoriji. Zato je predložen jednostavan alternativni metod, varijacija statičkog tilt-testa, koji ne zahteva nikakvu drugu mernu opremu osim senzora i ravne površine. Rezultati variraju u zavisnosti od kvaliteta površine i kućišta senzora, ali je pokazano da se efekti poprečne osetljivosti mogu smanjiti bar nekoliko puta, te da se tipična poprečna osetljivost komercijalnih troosnih MEMS akcelerometara od nekoliko procenata može lako svesti ispod 1%.

U okviru ovog rada osmišljen je i implementiran sustav za automatsko hranjenje kućnih ljubimaca kako bi se olakšao i unaprijedio način prehrane. Implementacija sustava je bazirana na Raspberry Pi uređaju. Sustav koristi ulazne jedinice poput senzora pokreta, težine, zvuka, temperature i vlage te kameru koje korisniku pružaju dodatne korisne informacije. Veliku komponentu sustava čini fizička konstrukcija hranilice kojom je moguće upravljati putem motora i releja koji su spojeni na Raspberry Pi. Web aplikacija implementirana u Flask radnom okviru omogućuje korisniku interakciju sa sustavom poput aktivacije hranjenja ili pregleda povijesnih podataka. Za pohranu podataka korištena je SQLite baza podataka. The aim of this master thesis was to design and implement an automated feeding system for pets in order to facilitate and improve the way of feeding them. The system implementation is based on the Raspberry Pi device. The system uses input units such as motion, weight, sound, temperature and humidity sensors, as well as a camera, that provide the user with additional useful information. A large component of the system is the physical construction of the feeder, which can be controlled via motor and relay connected to the Raspberry Pi. A web application implemented in the Flask framework allows the user to interact with the system, such as activating a feed or viewing historical data. SQLite database was used for data storage.

Goveđi serumski albumin (BSA) se često koristi kao model proteina za ljudski serumski albumin koji ima važnu ulogu u metabolizmu te postoji značajan interes prema razvoju metoda za njegovu osjetljiva i selektivna. U ovoj publikaciji priredili smo fluorescentne komplekse rutenija čija je fluorescencija ugašena u vodenom mediju, a obnavlja se vezanjem na BSA. Navedeno svojstvo omogućuje korištenje priređenih spojeva kao “Turn‐on“ fluorescentnih senzora za BSA. Isti spojevi su također i bio‐aktivni te pokazuju povećanje svoje toksičnosti prilikom osvjetljavanja, što ih čini potencijalnim kandidatima za fotodinamičku terapiju.

Promatranje malih vodenih tijela u stvarnom vremenu od velikog je značaja za prehrambenu i farmaceutsku industriju. Time se stječe uvid u bioraznolikost unutar različitih promjena u vodenom tijelu koja je uzrokovana vanjskim faktorima. S obzirom da je bioraznolikost flore i faune esencijalna za fotosintezu i druge važne prirodne procese, javlja se potreba za razvojem uređaja koji prate određene parametre unutar vodenog tijela i daju uvid u njeno stanje. Stoga će se u ovom radu opisati uređaj za mjerenje vodenih parametara malih vodenih tijela koja ukazuju na stupanj bioraznolikosti i zagađenja. Prvo će se definirati mala vodena tijela kao i mjerljivi parametri unutar njih. Nakon toga će se objasniti problem vezan uz trenutačne metode i tehnologiju mjerenja te će se analizirati tržište kao i patenti postojećih uređaja za mjerenja malih vodenih tijela. Na temelju istraživanja bit će definirani funkcionalni i eksploatacijski zahtjevi koji će poslužiti kao osnova za fazu koncipiranja. Posljedično se radi funkcijska dekompozicija. Promatraju se funkcije potrebne za rad proizvoda preko tokova energije i materije koja prolazi kroz uređaj. Iz dobivene funkcijske dekompozicije radi se morfološka matrica s glavnim funkcijama koje su potrebne za rad uređaja i pripadajuća tehnička rješenja. Pomoću morfološke matrice izrađuje se nekoliko koncepata čiji je rad opisan, a funkcije uspoređene. Određen je najbolji koncept te prenesen u daljnju konstrukcijsku razradu. U ovoj će se fazi proračunati konstrukcijska rješenja i standardne komponente koje su potrebne za rad uređaja. Rješenja će se detaljnije opisati pomoću izrađenoga modela te će biti objašnjeno zašto se koje koristilo. Za izradu modela koristi se programski paket SolidWorks 2020, a nakon izrade će se predložiti tehnička dokumentacija.

Izloženost onečišćenom zraku postaje sve veći uzročnik bolesti i razlog prijevremenih smrti u svijetu pa činjenica da se svakodnevno razvijaju i usavršavaju metode mjerenja emisija onečišćujućih tvari nije iznenađujuća. Cilj ovog rada jest proučiti i približiti danas najmoderniju tehnologiju mjerenja onečišćujućih tvari – besposadne letjelice. Zbog svoje učinkovitosti, brzine prikupljanja podataka i fleksibilnosti u integraciji više različitih senzora, besposadne letjelice omogućuju mjerenje s visokom rezolucijom čak i na čovjeku nepristupačnim mjestima. Rad daje uvid u vrste besposadnih letjelica kao i najčešće korištenih senzora koji metodom daljinskog istraživanja (engl. remote sensing) omogućuju prikupljanje traženih informacija od kojih je jedna i koncentracija prisutnih ispušnih plinova u atmosferi. Exposure to contaminated air is becoming an increasing cause of diseases and the reason for premature deaths in the world, so the fact that methods for emission measurement are being developed and perfected every day is not surprising. The purpose of this work is to study and bring closer the most modern technology for measuring pollutants – unmanned aerial vehicles. Due to their efficiency, speed of data collection and flexibility in the integration of multiple sensors, unmanned aerial vehicles provide measurements with high resolution even in places inaccessible to humans. The work gives an insight into the types of unmanned aerial vehicles as well as the most commonly used sensors that enable the collection of required information throught the mothod of remote sensing, one of which is the amount of exhaust gases present in the atmosphere.

U ovom radu istražuje se mogućnost predviđanja broja ljudi u danom prostoru kroz jakost Wi-Fi polja u određenim točkama prostora. Predviđanja ostvaruju algoritmi strojnog učenja iz podataka generiranih kroz simulaciju i eksperiment. Iako rezultati na eksperimentalnim podacima nisu zadovoljavajući, istraživanje na podacima iz simulacije daje obećavajuće rezultate s obzirom na to da je najveća točnost predviđanja oko 69%. This paper investigates the possibility of predicting the number of people in a given space through the strength of Wi-Fi signal in certain points of space. Predictions are made by machine learning algorithms from data generated through simulation and experiment. Although the results of the experiment data are not satisfactory, research on simulation data give promising results considering that the highest prediction accuracy is around 69%.

U svijetu koji se sve više bavi zelenom tranzicijom u svrhu sprječavanja klimatskih promjena, veliki fokus se stavlja na štednju energije. Znamo da se značajan postotak energije troši na hlađenje i grijanje prostorija u kojima boravimo i nužno je minimizirati nepotrebne troškove gdje je to moguće kako bismo smanjili opterećenje na infrastrukturu, a i okoliš. U ovom radu proučavamo pristupačan način uštede energije za postojeće građevine, pomoću pametnog termostata. Koristeći se strojnim učenjem i raznim senzorima pokušavamo neinvazivno predvidjeti stanje otvorenosti prozora kako bismo mogli upozoriti korisnika ukoliko je klima upaljena da zatvori prozor ili ugasi klimu. Model se naposlijetku pokazao neuspješnim ali daje puno korisnih informacija za daljnji razvitak. In a world that is increasingly concerned with the green transition to prevent climate change, great emphasis is being placed on saving energy. We know that a significant percentage of energy is spent on cooling and heating the rooms in which we reside and it is necessary to minimize unnecessary costs where possible to reduce the burden on infrastructure and the environment. In this paper, we study an affordable way to save energy for existing buildings, using a smart thermostat. Using machine learning and various sensors, we try to non-invasively predict the state of window openness so that we can warn the user if the air conditioning is on to close the window or turn off the air conditioning. The model eventually proved unsuccessful but provides a lot of useful information for further development.

U ovom radu konstruirao se pogonski sustav za samostalno kretanje invalidskih kolica pri ukrcaju u vozilo. Kako je takvo kretanje analogno mobilnim robotima, prvo su opisani pojmovi mobilne robotike i njihova podjela kako bi se lakše shvatila izrada zadatka. Nakon razrade pogonskih sustava kod mobilnih robota, zaključeno je da će ovaj projekt biti mobilni robot s diferencijalnim pogonom. Nadalje su se istražila i postojeća rješenja pogonskih sustava na tržištu kako bi se ovo rješenje razlikovalo od drugih u određenoj mjeri. Predstavljena su tri idejna koncepta i njihovom evaluacijom izabran je onaj koji ima najbolju ocjenu. Odabrano rješenje koristi tarni prijenos s kotačića na kotač kako bi prenijelo potrebno snagu. Konstruirani su i potrebni nosači te stezaljke za pravilno montiranje sustava na invalidska kolica. Nakon proračuna odabran je i pripadni motor. Da bi to sve funkcioniralo i da bi invalidska kolica mogla izvršiti ukrcaj i iskrcaj iz vozila razradio se način upravljanja i kontrole cijelim sustavom., This thesis is about projecting a „Power add on“ system on manual wheelchair so that the wheelchair can go into the vehicle and back autonomously. This project is analogues to mobile robotics so these terms were first described to make the task easier to understand. After the development of propulsion systems for mobile robots, it was concluded that this project will be a mobile robot with differential drive. Existing „Power add on“ system solutions on the market were furher explored to differentiate this solution from others. Three concepts were presented and evaluated. The solution with the best grade was chosen. The selected solution uses friction transmission to transfer the required power. The necessary brackets and clamps for proper assemble of the system on wheelchair have also been designed. After the calculation, the coressponding engine was selected. In order for all this to work and for the wheelchair to be able to go in and out from the vehicle, a way of managing and controlling the entire system was developed.

Sustavi za nadgledanje i održavanje tramvajskih trasa su skupi, komplicirani i dugotrajni, stoga trebaju modernizaciju. Ovaj rad donosi umjetnu inteligenciju kao sredstvo predviđanja degradacije. Za treniranje različitih modela strojnog učenja bilo je potrebno prikupiti senzorske podatke, analizirati ih i označiti kako bi se mogli okoristiti nadziranim učenjem. Podaci su prikupljeni s napravljenom aplikacijom i mobilnim uređajem koji ima inercijske senzore akcelerometar i žiroskop. Uz mogućnost GPS-a implementirani sustav može oslikati područja različite alarmantnosti degradacije, informacija koja bi mogla biti prijeko potrebna nadležnim tijelima za ekonomičniju raspodjelu resursa. Tram route monitoring and maintenance systems are expensive, complicated and time consuming, so they need modernization. This paper brings artificial intelligence as a means of predicting degradation. To train different models of machine learning, it was necessary to collect sensory data, analyze them and label them, so that they could benefit from supervised learning. An android application for gathering data was developed and installed on a mobile device that has inertial sensors accelerometer and gyroscope. With the utillization of GPS, the implemented system can map areas of different degradation levels, information that could be indispensable to the monitoring authorities for a more economical allocation of resources.
