Analysis of the USB standard as a power supply
No full textRazvojem USB tehnologije povećava se i broj uređaja koji se napajaju pomoću USB kabela.
Pregled USB tehnologije napravljen je kroz razvoj USB standarda i njihovih priključaka. Kod
razvoja USB standarda stavljen je naglasak na njihovu sposobnost upravljanja snagom
napajanja. Za potpuni proces punjenja, osim USB kabela potrebni su i električni energetski
pretvarači. Iako se u praktičnom dijelu ovog rada najviše koriste AC/DC ispravljači, napravljen
je teorijski pregled za sve vrste pretvarača. Praktični dio odrađen je kroz mjerenje strujno
naponskih prilika na USB portu prilikom punjenja tri različita uređaja. Pružen je pregled uređaja
koji se koriste prilikom ove vrste mjerenja, te je detaljno opisan princip rada i mogućnosti
korištenog uređaja (JT-UM25C). Analizom podataka dobivenih iz provedenih mjerenja
utvrđena su trenutna stanja baterija uređaja te njihov kapacitet. Obrazložene su prednosti i
nedostaci periodičnog mjerenja.The development of USB technology has led to an increase in the number of devices powered by
USB cables. An overview of USB technology has been made through the development of USB
standards and their connectors. When developing USB standards, emphasis was placed on their
power management capability. For a complete charging process, in addition to the USB cable,
electrical power converters are required. Although AC/DC adapters are most commonly used in
the practical part of this work, a theoretical overview has been provided for all types of converters.
The testing was conductetd by measuring the current-voltage conditions at the USB port when
charging three different devices. An overview of the devices used for this type of measurement is
provided, and the operating principle and capabilities of the used device (JT-UM25C) are
described in detail. The analysis of the data obtained from the measurements determined the
current state of the device batteries and their capacity. The advantages and disadvantages of
periodic measurements are explained

programming language and the Cucumber tool. Testing confirmed the fulfillment of both
functional and non-functional requirements of the system
Ionizing radiation and technical applications
No full textU ovom završnom radu cilj je bio opisati povijest otkriće same radioaktivnosti te se usmjeriti
na ionizirajuće zračenje i njegovu podjelu na alfa, beta i gama zračenje. Objašnjene su mjerne
jedinice kao i mjerni instrumenti ionizirajućeg zračenja. Poseban naglasak je na štetnim
učincima ionizirajućeg zračenja koji mogu dovesti do ozbiljnih zdravstvenih posljedica.
Unatoč potencijalnoj štetnosti, ionizirajuće zračenje ima mnoge korisne primjene u medicini,
industriji i istraživanjima, poput radioterapije u liječenju raka, dijagnostike bolesti i
sterilizacije materijala. Provedenim mjerenjem utvrđeni su iznosi zračenja nekih dostupnih
radioaktivnih materijala te je zaključeno kako beta light emiter uzrokuje najveće zračenja u
odnosu na prirodno pozadinsko zračenje.The aim of this thesis was to describe the history of the discovery of radioactivity, with a
focus on ionizing radiation and its division into alpha, beta, and gamma radiation. The units
of measurement and measuring instruments for ionizing radiation were explained. Special
emphasis was placed on the harmful effects of ionizing radiation, which can lead to serious
health consequences. Despite its potential hazards, ionizing radiation has numerous beneficial
applications in medicine, industry, and research, such as in cancer treatment through
radiotherapy, disease diagnosis, and material sterilization. By conducting measurements, the
levels of radiation from certain available radioactive materials were measured, and it was
concluded that beta light emitters cause the highest radiation compared to natural background
radiation
Graphical representation of matrices operations in C programming language #
No full textGlavni zadatak ovog završnog rada je napraviti Windows desktop aplikaciju koja će predstavljati
grafički prikaz operacija s matricama. Pri pisanju programskog koda korišten je programski jezik
C#, a kao razvojno okruženje korištena je Microsoft Visual Studio aplikacija. Također, korištene
su Windows forme kao dio Microsoft .NET platforme za grafički prikaz ukupno pet formi. Prva
forma predstavlja početni prozor aplikacije u kojem se pomoću padajućeg izbornika bira neka od
sljedećih operacija: zbrajanje, oduzimanje, množenje te množenje sa skalarom. Druga forma
predstavlja prozor u kojem korisnik upisuje dimenzije matrica A i B potrebne za operacije
zbrajanja, oduzimanja i množenja. Treća forma predstavlja prozor za upis elemenata matrica A i
B te joj je glavna zadaća izračunavanje rezultantne matrice klikom na gumb. Također, posjeduje i
mogućnosti koje se izvode klikom na odgovarajući gumb, a podrazumijevaju: povratak na
prethodnu formu, povratak na početnu formu i „čišćenje“ svih matrica na početno stanje. Četvrta
se forma odnosi na prozor u kojemu korisnik upisuje dimenzije matrice i skalar koji su potrebni
za operaciju množenja matrice sa skalarom. Zadnja, peta forma predstavlja unos elemenata
matrice, a glavna zadaća joj je izračunavanje rezultantne matrice. Ona posjeduje sve mogućnosti
kao i treća forma uz dodatak da korisnik u svakom trenutku može promijeniti vrijednost skalara
koju je prethodno upisao u četvrtoj formi. Aplikacija je otporna na neispravne unose od strane
korisnika, primjerice neispravan unos dimenzija matrice, neispravan unos skalara, neispravan unos
elemenata matrice i tako dalje.The main task of this final paper is to create a Windows desktop application that will represent a
graphical display of operations with matrices. The programming language C# was used when
writing the program code, and the Microsoft Visual Studio application was used as the
development environment. Also, Windows Forms were used as part of the Microsoft .NET
platform for graphical display of a total of five forms. The first form represents the initial window
of the application in which one of the following operations is selected using the drop-down menu:
addition, subtraction, multiplication and multiplication with a scalar. The second form represents
a window in which the user enters the dimensions of matrices A and B needed for addition,
subtraction and multiplication operations. The third form represents a window for entering the
elements of matrices A and B, and its main task is to calculate the resultant matrix by clicking on
the button. It also has options that can be performed by clicking on the corresponding button,
which include: return to the previous form, return to the initial form and "cleaning" all matrices to
their initial state. The fourth form refers to the window in which the user enters the dimensions of
the matrix and the scalar required for the operation of multiplying the matrix with a scalar. The
last, fifth form represents the entry of matrix elements, and its main task is to calculate the resultant
matrix. It has all the same possibilities as the third form with the addition that the user can change
the value of the scalar previously entered in the fourth form at any time. The application is resistant
to incorrect inputs by the user, for example incorrect input of matrix dimensions, incorrect input
of scalar, incorrect input of matrix elements and so on
