Developing a Parking Monitoring System Based on the Analysis of Images from an Outdoor Surveillance Camera 
In this paper, we describe a solution for monitoring of parking availability based on computer vision. It allows us to detect and track cars in a parking lot, while collected historical data helps us to predict availability status of parking during the day based on data mining techniques. Parking Monitoring System tracks availability based on an analysis of images from an outdoor surveillance camera and analyzes in real time the state of the parking complex. The system is developed to determine the number and location of available parking places and to inform the drivers. We provide an algorithm for image capture and analysis to recognize a car in a parking lot and to define parking spaces as either reserved or free.

Use of HLA During Customer Flow Simulation in a Polyclinic 
This article covers application of distributed simulation for creation of a simulation model of a policlinic. The goal was to monitor the individual patient flows (further referred to as “customer flows”) during day-to-day operation, during exceptional situations and above all, to study the effects of exceptional situations on the system. This project is specific in terms of framing several bachelors’ theses, which overlap into practice. The article briefly covers the chosen technology, motivation behind the selection of the technology, the principle of data collection and processing, methods of validation and verification, and the principle of creation of alternative scenarios and their evaluation. A discussion on the topic of suitability and advantages of using HLA instead of common monolithic simulator or simulation tool is also a part of the article.

Revealing the Structure of Domain Specific Tweets via Complex Networks Analysis 
In this paper we explore the relation between different groups of tweets using complex network analysis and link prediction. The tweets were collected via the Twitter API depending on their textual content. That is, we searched for the tweets in English language containing specific predefined keywords from different domains. From the gathered tweets a complex network of words was formed as a weighted network. Nodes represent words and a link between two nodes exists if these two words co-occur in the same tweet, while weight denotes the co-occurrence frequency. The Twitter search was repeated for four different search criteria (API queries based on different tweet keywords), thus resulting in four networks with different nodes and links. The resulting networks were subjects to further network analysis, as comparison of numerical properties for different networks and link prediction for individual networks. This paper shows the tweet scraping process, our approach to building the networks, the measures we calculated for them, the differences and similarities between different networks we built and our success in predicting future links.

Counting Prime Numbers in Paralell - Faster by Reducing the Synchronization Overhead 
This paper illustrates comparison of sequential and parallel execution of algorithm that counts prime numbers between 1 and N. Many systems rely on problems in number theory, where primes have an important role. Primes are used for encryption and hash functions too. In order to reduce the complexity of sequential algorithm execution, which is O(n^2), and also to achieve speedup, the algorithm was parallelized and some parts of it were additionally optimized by saving time on barriers. OpenMP tool is used as an application programming interface for parallelization. Sequential and parallel algorithm performances were measured on different architectures, based on Intel i3 and i7 processors, and the results, as well as the achieved speedup, are presented in the paper.

Parallelization Challenges of BFS Traversal on Dense Graphs Using the CUDA Platform 
This paper presents challenges encountered while parallelizing an existing sequential algorithm. A breadth-first search implementation in CUDA C++, of quadratic time complexity, is used. Even though BFS might seem like an easily parallelizable problem due to many independent iterations over graph vertices, there are other important aspects which need to be considered. Properties like granulation, communication and load balancing are thoroughly examined to find their exact impact in BFS. The implementation is profiled to find bottlenecks and problems which prevent its further optimization.

Security and Privacy in an IT Context – a Low-cost WIDS Employed against MITM Attacks (concept) 
WiFi (802.11) is as widespread as it is a source of potential security breaches. Even though the lay user base typically feels protected by employing basic encryption (first WEP, then WPA and currently WPA2), the truth is that it is trivially easy to perform a multitude of attacks on typical home and small business setups. This paper will cover the danger of a MITM1 ) attack as well as fairly straightforward steps one might take to prevent such intrusions by implementing a basic WIDS2 setup with off-the-shelf hardware and open source software.

Buck Converter Controlled by Arduino Uno 
The paper presents a buck converter controlled with microcontroller integrated on Arduino Uno board. The control is implemented by use of PI controller embedded on Arduino Uno board. Open loop control-to-output transfer function is obtained from measured step response. The PI controller and feedback divider transfer functions are synthesized to get desired loop gain. As a verification of analysis, input voltage step responses of regulated and unregulated buck converter are compared and improvements are identified.

Heart Rate Variability Analysis Using Different Wavelet Transformations 
Heart rhythm is modulated by the autonomic nervous system in order to adapt to changing cardiovascular loads. The resulting heart rate variability (HRV) is considered as one of the most promising non-invasive markers of the activity of the autonomic nervous system. In this work, the possibility to analyze HRV with wavelet transform was investigated. Specifically, three methods of wavelet transform (CWT, CWTFT and DWT) were compared. DWT showed to be the best one because of the simplicity of decomposition, and quality of reconstruction, high time resolution as well as the shortest computation time and lowest CPU power consumption. DWT showed to have high noise robustness, excellent temporal and good frequency resolution and small influence of the mother wavelet type. ULF, HF and LF components of HRV were assessed using DWT transform. LF/HF ratio was extracted from HRV signal during voluntary breathing apneas and compared to the respiration signal. An increase in LF/HF ratio corresponding to the times of breathing apnea could be observed, indicating that the proposed method could reveal specific changes in the HRV and that LF/HF ratio could serve as a good indicator of breathing apnea.

Istraživanje ransomware napada i prijedlozi za bolju zaštitu 
Ransoware zlonamjerni programi napravili su veliku štetu organizacijama ali i pojedincima. Predviđanja za 2016. godinu navode da će ransomware biti jedna od najvećih prijetnji u ovoj godini, kako za tvrtke tako i za pojedince. Dosadašnje iskustvo pokazalo je da su najčešći vektori napada iskorištavali korisničko neznanje ali i neažuriranje softverskih paketa na napadnutim računalima. Ovaj rad predstavit će rezultate istraživanja na napadnutim sustavima, vektore napada, razloge koji su doveli do zaraze te prijedloge za poboljšanje zaštite od ove vrste zlonamjernih programa.

Audio Phonebook for the Blind People 
The technology can in many ways help visually impaired people, but problem of memorizing a large number of phone numbers for most of blind people is still not resolved. The aim of this study was to design, construct and test a device that would serve as a phone book for landline phones. The device is connected between the phone and the phone line and therefore can serve as a memory for phone numbers. It is important that it has a very simple interface and allows unobstructed use of the phone. The device was tested by visually impaired people from the Croatian association of the blind and feedback showed that it could be used without any problem and without special training.
