Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Exploiting loopholes in network protocols and protecting computer networks
Krajem 20-og stoljeća dolazi do široke primjene Internet tehnologije u društvu. Komercijalizacijom informatičke opreme dolazi do značajnog pada cijena informatičke opreme čime ista postaje dostupna i privatnim korisnicima. Masovno korištenje informatičke opreme dovodi do razvoja Interneta u svrhu brze povezanosti i izrade raznih informativnih sadržaja koji su brzo dostupni. Rastom podataka na Internetu dolazi do potrebe za povećanjem brzine i propusnosti prijenosa podataka te razvojem kvalitetnije mrežne opreme te izradom raznih protokola koji omogućuju opremi funkcioniranje bez potrebe za intervencijom stručnjaka pri kvaru pojedinog segmenta mreže ili pojedinog djela mrežne opreme. Općom dostupnosti Interneta dolazi do zlouporabe istog za iskorištavanje raznih sigurnosnih propusta u protokolima i aplikacijama. U ovom radu opisujemo radni okvir Yersinia koji služi za provjeru i iskorištavanje propusta u nekim protokolima koji se koriste pri radu mrežne opremeAt the end of the 20th century, Internet technology was widely used in society. The commercialization of IT equipment leads to a significant drop in prices of IT equipment, which makes it available to private users as well. The mass use of IT equipment leads to the development of the Internet for the purpose of fast connection and the creation of various informational contents that are quickly available. With the growth of data on the Internet, there is a need to increase the speed and bandwidth of data transmission and to develop better quality network equipment and create various protocols that enable the equipment to function without the need for expert intervention in the event of failure of a particular segment of the network or a particular part of the network equipment. Due to the general availability of the Internet, it is misused to exploit various security flaws in protocols and applications. In this paper, we describe the Yersinia framework that is used to check and exploit vulnerabilities in some protocols used in the operation of network equipment

Planning and optimization of wireless local networks
Cilj ovog završnog rada je objasniti bežične lokalne mreže i njihovo planiranje i optimizaciju. Bežične lokalne mreže postale su alternativna zamjena žičanim mrežama. Ukoliko nam je potrebna mreža koja nije ograničena fizičkim medijem, jeftinija je i jednostavnija za instalaciju, a također nam i nudi veću slobodu kretanja, u tom slučaju biramo bežičnu lokalnu mrežu. U prvome dijelu rada objašnjeni su osnovni pojmovi poput: frekvencije, EIRP, decibela, frekvencijskih pojaseva i interferencija. Također su detaljnije opisane antene bežičnih uređaja, njihove karakteristike i tipovi. Bitno je opisati temeljne pojmove u prvome dijelu rada kako bih bolje približio samo planiranje i optimizaciju bežičnih lokalnih mreža. U drugome dijelu rada govori se o 802.11 okvirima, pokrivenosti područja AP-ovima i optimizaciji mreže.The aim of this thesis is to explain wireless local area networks and their planning and optimization. Wireless local networks have become an alternative to wired networks, if we need a network that is not limited by physical media, which is cheaper and easier to install, and which offers us greater freedom of movement, we choose a wireless local network. In the first part of the work, basic terms such as: frequency, EIRP, decibels, frequency bands and interference are explained. Antennas of wireless devices, their characteristics and types are also described in more detail. It is important to describe the basic terms in the first part of the paper in order to make it easier to understand the planning and optimization of wireless local networks. The second part of the paper discusses 802.11 frames, area coverage by AP-s and network optimization
Creating network infrastructure using open-source infrastructure as code and cloud service providers
Ovaj rad istražuje izradu pouzdane, dinamički skalirajuće mrežne infrastrukture koristeći infrastrukturu kao kod (IaC) i poslužitelja u oblaku, s fokusom na Terraform i Amazon Web Servise. Rješenje je izrađeno prema industrijskim najboljim praksama, kombinirajući tehnologije temeljene na klasicima , linux poslužiteljima i tehnologiji bez poslužitelja, radi maksimalne učinkovitosti i fleksibilnosti. Terraform se koristi kao glavni IaC alat za automatizaciju konfiguracije i upravljanja resursima u oblaku. AWS je odabran kao pružatelj usluga u oblaku zbog svojih širokih usluga i globalnog dosega. Infrastruktura je dizajnirana s dva odvojena virtualna privatna oblaka, jedan za korisnike i jedan za razvoj, kako bi se osigurala pouzdanost usluge. Automatsko skaliranje je implementirano kako bi se alokacija resursa dinamično prilagodila potražnji, osiguravajući optimalnu pouzdanost, performanse i isplativost. Koriste se EC2 instance, temeljene na linux operacijskom sustavu za web poslužitelje i računanje bez poslužitelja poput AWS Lambda za stvaranje hibridne infrastrukture koja može podnijeti različita opterećenja. Git se koristi za verzioniranje i omogućuje suradnju u upravljanju IaC kodom. Naglasak je na pouzdanost, skalabilnost i sigurnost uz pridržavanje industrijskog standarda za arhitekturu u oblaku. Primjenom IaC osigurava se konzistentnost i agilnost infrastrukture u razvojnim i produkcijskim okruženjima.This paper explores the development of a reliable, dynamically scalable network infrastructure using Infrastructure as Code (IaC) and cloud providers, with a focus on Terraform and Amazon Web Services. The solution is built according to industry best practices, combining technologies based on classic Linux servers and serverless technology for maximum efficiency and flexibility. Terraform is used as the primary IaC tool for automating the configuration and management of cloud resources. AWS was chosen as the cloud service provider due to its extensive services and global reach. The infrastructure is designed with two separate virtual private clouds, one for users and one for development, to ensure service reliability. Auto-scaling is implemented to dynamically adjust resource allocation based on demand, ensuring optimal reliability, performance, and cost-efficiency. EC2 instances, based on the Linux operating system, are used for web servers, while serverless computing like AWS Lambda is employed to create a hybrid infrastructure capable of handling varying workloads. Git is used for version control, enabling collaboration in managing the IaC code. The focus is on reliability, scalability, and security while adhering to industry standards for cloud architecture. The application of IaC ensures consistency and agility in infrastructure across both development and production environments

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Prioritization of IP Packets and Quality of Service Planning in a Three-Layer Network Design
Ovaj rad istražuje prioritizaciju IP paketa i planiranje kvalitete usluge (QoS) unutar troslojnog dizajna mreže, s posebnim naglaskom na konvergirane mreže i njihov utjecaj na performanse mreže. Rad detaljno analizira različite tipove QoS, uključujući Best-Effort, Integrated Services (IntServ) i Differentiated Services (DiffServ), te mehanizme poput upravljanja propusnošću, kontrole latencije i upravljanja gubitkom paketa. Fokus je stavljen na implementaciju QoS u stvarnom okruženju kroz studiju slučaja hotela Valamar, gdje su analizirani konkretni izazovi i rješenja. Razmatraju se strategije za upravljanje preopterećenim mrežama, uključujući praćenje performansi i optimizaciju resursa. Rezultati studije pokazali su kako pravilna primjena QoS politika može poboljšati korisničko iskustvo i učinkovitost mreže u konvergiranim okruženjima. Zaključno, rad pruža uvid u značaj QoS u modernim mrežnim dizajnima i njegove prednosti za kompleksne mrežne infrastrukture.This paper explores IP packet prioritization and quality of service (QoS) planning within a three-layer network design, with a particular focus on converged networks and their impact on network performance.
