Hospital Examination Patient Scheduling Efficiency
No full textOvaj rad bavi se učinkovitim raspoređivanjem pacijenata na bolničke preglede
koristeći tri različita algoritma: First-Come First-Served, Priority Scheduling i cjelobrojno linearno
programiranje. Cilj istraživanja bio je smanjiti vrijeme čekanja pacijenata i poboljšati učinkovitost
korištenja zdravstvenih resursa. Rezultati su pokazali da je ILP algoritam ostvario najbolje performanse,
smanjivši vrijeme čekanja za 60,46%, dok su FCFS i PS algoritmi postigli smanjenje od 55,66% i 11,92%. U
istraživanju smo koristili tehnologije poput programskog jezika Python i biblioteka kao što su Pandas za
manipulaciju podacima te PuLP za rješavanje problema linearnog programiranja. Ovi alati omogućili su
nam učinkovito modeliranje i analizu problema raspodjele pacijenata, naglašavajući važnost naprednih
algoritama u optimizaciji zdravstvenih sustava.This paper addresses the efficient scheduling of patients for hospital examinations using three
different algorithms: First-Come First-Served, Priority Scheduling, and Integer Linear Programming. The
aim of the research was to reduce patient waiting times and improve the efficiency of healthcare
resource utilization. The results showed that the ILP algorithm achieved the best performance, reducing
waiting time by 60.46%, while the FCFS and PS algorithms achieved reductions of 55.66% and 11.92%. In
this research, we utilized technologies such as the Python programming language and libraries like
Pandas for data manipulation and PuLP for solving linear programming problems. These tools allowed us
to effectively model and analyze the patient scheduling problem, highlighting the importance of
advanced algorithms in optimizing healthcare systems
Chatbot integration in Django REST Framework
No full textGlavni problem ovog završnog rada dijeli se na dva dijela, prvi problem je kreiranje
chatbot sučelje koje pruža sve osnovne funkcionalnosti chatbota poput razgovora, a drugi problem koji
se nadovezuje na prvi je omogućiti njegovo korištenje diljem weba kroz ubacivanje skripte u HTML
dokument. Kako bi se to postiglo bilo je potrebno istražiti teoriju chatbotova, njihove karakteristike i
kako rade, zatim istražiti tržište i provjeriti postoji li slično rješenje. U radu su opisana dva postojeća
chatbota Zoho SalesIQ Zobot i Chatbox koji su najsličniji autorovu rješenju. Nadalje, integracija OpenAI
API-ja s autovorim API-jem je ključan dio u osposobljavanju funkcionalnosti chatbota, također je u radu
opisan princip na koji se generira tekst od strane LLM-ova (engl. Large Language Model). Pred kraj je
opisan arhitekturalni stil weba REST kojeg se bilo potrebno držati tijekom cijele izrade praktičnog dijela
rada, dakako, opisane su krajnje točke web aplikacije na poslužiteljskom dijelu i kompletno sučelje i
arhitektura klijentskog dijela aplikacije. Na poslijetku je zadatak rada u potpunosti izvršen uz mogučnost
unaprijeđenja kompletne aplikacije u pogledu bolje autorizacije korisnika i dizajna sučelja.The main problem of this thesis is divided into two parts. The first problem is creating a
chatbot interface that provides all the basic functionalities of a chatbot, such as conversation. The
second problem, which builds on the first, is enabling its use across the web by embedding a script into
an HTML document. To achieve this, it was necessary to research the theory of chatbots, their
characteristics, and how they work, followed by market research to check for similar solutions. The
thesis describes two existing chatbots, Zoho SalesIQ Zobot and Chatbox, which are most similar to the
author's solution. Furthermore, the integration of the OpenAI API with the author's API is a crucial part
of enabling the chatbot's functionalities. The thesis also describes how text is generated by LLMs (Large
Language Models). Toward the end, the architectural style of the web, REST, is described, which needed
to be followed throughout the practical part of the work. Additionally, the endpoints of the web
application on the server side, along with the complete interface and architecture of the client side of
the application, are described. Finally, the task of the thesis was fully accomplished, with potential
improvements in the overall application regarding better user authorization and interface design

diagram was created in the Matlab/Simulink program, and the simulation results for the most important
variables were presented in the form of a table in the attachment and time graphs
Linear sharpened raised-cosine antenna array
No full textOvaj diplomski rad se bavi dizajnom antenskih nizova s uskim dijagramom zračenja.
Prilikom dizajna linearnih antenskih nizova koriste se metode identične metodama za dizajn digitalnih
FIR filtara, kao što je metoda prozora. Opisana je primjena Dolph-Chebyshevljeva prozora koji se
konstruira uz pomoć Chebyshevovih polinoma. Prozor je definiran tako da njegove bočne latice
odgovaraju dijelu Chebyshevovog polinoma s jednakim oscilacijama. Dodavanje faznog zakreta
omogućava usmjeravanje zraka antenskog niza u željenom pravcu. Nadalje, opisana je metoda za dizajn
oštrih FIR filtara s brzim padom prijenosne karakteristike prema zapornom području primjenom
aproksimacije dijagrama zračenja Fourierovim redom i minimizacijom srednjeg kvadratnog odstupanja
aproksimacije od željenog dijagrama. Navedena metoda se temelji na frekvencijskom odzivu dobivenom
polinomskim izoštravanjem prijelaznog pojasa s funkcijom uzdignutog kosinusa. U ovom radu je
predstavljen opis dizajna FIR filtara s izoštrenim amplitudnim odzivom uzdignutog kosinusa, koja
omogućava izravnu kontrolu prijelaznog pojasa filtra i poboljšava lokalizaciju odziva u vremenu.
Prikazana je primjena ovih filtara u sustavima za maskiranje frekvencijskog odziva, čime se postiže
optimizacija za uske i široke prijelazne pojaseve te preciznije usmjeravanje antenskog niza.This final thesis deals with the design of antenna arrays with a narrow beampattern. When
designing linear antenna arrays, methods identical to those for designing digital FIR filters, such as the
window method, are used. The application of the Dolph-Chebyshev window, which is constructed with
the help of Chebyshev polynomials, is described. The window is defined so that its side lobes correspond
to the part of the Chebyshev polynomial with equal oscillations. Adding a phase shift enables the beam
of the antenna array to be directed in the desired direction. Furthermore, a method is described for the
design of sharp FIR filters with a rapid drop in the transmission characteristic towards the blocking
region by applying the Fourier series approximation of the radiation diagram and minimizing the mean
square deviation of the approximation from the desired diagram. The mentioned method is based on
the frequency response obtained by polynomial sharpening of the transition band with the raised cosine
function. The paper also includes a description of the design of an FIR filter with a sharpened raised
cosine amplitude response, which allows direct control of the filter transition band and improves the
localization of the response in time. The application of these filters in frequency response masking
systems is presented, which achieves optimization for narrow and wide transition bands and more
precise routing of the antenna array
