The impact of traffic flow speed on emissions of harmful gases on highways in the Republic of Croatia
No full textRad analizira koliki je utjecaj brzine prometnog toka na emisiju štetnih plinova na autocestama
u Republici Hrvatskoj. Upotrebom softverskog alata Copert Street Level, proučavane su
emisije ugljikovog dioksida, ugljikovog monoksida, dušikovih oksida, lebdećih čestica i
hlapljivih organskih spojeva pri različitim brzinama i scenarijima. Analizirani su scenarij
trenutnog stanja, smanjene operativne brzine i smanjene ograničenja brzine. Rezultati
pokazuju kako se smanjenjem brzine mogu smanjiti emisije pojedinih štetnih plinova, dok se
istovremeno može povećati razina emisije drugih. Evaluacijom rezultata prikazuju se ukupne
emisije plinova na svima autocestama u Republici Hrvatskoj ovisno o svakom scenariju.
Scenarij 0 za analizu podataka uzima propisano ograničenje brzine, scenarij 1 za analizu koristi
operativnu brzinu na autocestama u Republici Hrvatskoj koja je veća od ograničenja brzine, a
scenarij 2 temelji se na smanjenju postojećeg ograničenja brzine od 130 kilometara na sat na
120 kilometara na sat. Rad ističe važnost održavanja optimalne brzine prometnog toka,
izbjegavanje znatno niskih i visokih brzina, poticanje ekološke vožnje i uporabu alternativnih

the same time the emission level of others can be increased. The paper highlights the
importance of maintaining the optimal speed of the traffic flow, avoiding significantly low and
high speeds, encouraging ecological driving and the use of alternative fuels to reduce the
impact of harmful gas emissions from road traffic on the environment
Online Gaming Performance Analysis in Fifth Generation Mobile Networks
No full textCilj ovog završnog rada je analizirati mrežne performanse pri igranju igara na mobilnim
mrežama pete generacije (5G). 5G je relativno nova tehnologija i ovakvom se analizom gleda
kako umreženo igranje funkcionira preko mobilnih mreža u usporedbi s umreženim igranjem
klasičnim putem, odnosno žičanom vezom. Potrebno je vidjeti je li 5G mreža nužna za igranje
svih tipova igara ili samo za neke vrste. Sagledat će se koju razinu kvalitete usluge mora imati
pojedini tip igre da bi iskustvena kvaliteta bila u zadovoljavajućim mjerama. Na primjerima
triju igara koje imaju elemente svih ostalih vrsta igara izvest će se mrežna analiza. Testirat će
se kašnjenja prema poslužiteljima za Battle Royale vrstu igre, koja je ujedino i najbolji
pokazatelj razloga za korištenje 5G mreže za igranje. Nova tehnologija igranja u oblaku bit će
obrađena, jer ima vrlo slične karakteristike kao umreženo igranje. Objasnit će se i nova
tehnologija rukovanja podatcima u 5G jezgrenoj arhitekturi, koja se zove rubno računalstvo
(edge computing) zbog kojeg igranje u oblaku i umreženo igranje radi s puno boljim
performansama.The goal of this final paper is to analyse network performance when playing games on the
fifth generation mobile networks (5G). 5G is a relatively new technology and this analysis
looks at how networked gaming works over mobile networks compared to networked gaming
via a traditional wired connection. It remains to be seen whether the 5G network is necessary
for playing all types of games or only for some types. The level of service quality a particular
type of game must have in order for the quality of experience to be satisfactory will be
discussed. A network analysis will be performed on the examples of three games that have
elements of all other types of games. Latencies toward the servers for the Battle Royale type
of game will be tested, since this type is the best indicator of the reason to use a 5G network
for gaming. The new cloud gaming technology will be addressed, since it has similar
characteristics to networked gaming. The new data handling technology in the 5G core
architecture called edge computing will be explained, as it makes cloud and networked
gaming work with better performance
