Model-based Verification of the SIP Invite Scenario 
The Session Initiation Protocol (SIP) is a signaling protocol for multimedia control over the Internet. It is used for initiating, maintaining and terminating multimedia sessions. In this paper we have carried out the verification of the SIP Invite scenario with Coloured Petri nets (CP-nets or CPNs). First, we have specified and verified the protocol model using a simulation tool. Then, we have verified the scenario using a state space analysis tool. We have concluded that the SIP Invite transaction is free of livelocks, and has only desirable deadlocks. Therefore, no additional remodeling for the protocol Invite transaction is needed.

Reliability Sensitivity Analysis for Yahoo! Pipes Mashups
Development of Web technologies has pushed forward a wide array of tools which can be used by the end-users to customise their own environment. Mashup development frameworks stand out as means to create Web apps by combining the existing content or functionality provided by various, disparate, providers on the Web. Like for all composite systems, reliability is one of the primary design concerns in mashup development. This is due to the fact that the content used in the mashup is often not under the supervision of the mashup developer and is rather deployed on the Web by a third-party provider. In this paper a reliability sensitivity analysis is conducted for the collected dataset of Yahoo Pipes. Reliability of each mashup in the dataset is estimated using a reliability model based on belief networks. A sensitivity analysis is conducted on the reliability models to ascertain which building components have the greatest impact on the overall reliability of the dataset.

Requirement Bottlenecks in a Cloud Based SCADA System
High expectations of the cloud hold great promises for computer scientists and engineers. However, its applications in real-time systems, especially in SCADA, are still in infancy stage. Besides, while there were a lot of researches working on integrating scientific systems on cloud systems, even the study on the mentioned topic was limited. Therefore, the authors seek to address some major issues in creating a cloud compatible real-time SCADA system. These are: data storage and database management, security of a system hosted on the cloud and system failure and recovery on the cloud.
Given the criticality of SCADA applications, many trust issues have been raised regarding cloud security. Engineers in a high security institution are understandably reluctant to opening ports to a third party cloud provider over the Internet. Additionally, it would be difficult to maintain a security system that incorporates the cloud provider. So, we propose to implement the security firewall around the cloud service, deployed on a cloud system, itself, which is paired with only the security on the outstations and clients.

Impact of Control Flow Blocks Granularity on Custom Processor Design Time
One of the key issues for system level design topic is the design time. This paper describes custom processor design as part of high level synthesis flow and analyses its design time. The flow starts with C code specification and ends with FPGA implementation. The way the C code is processed has impact on the flow execution time. The implemented C code processing results with Control Flow Graph (CFG) where large control flow code blocks severely prolong the overall design time, and variations in their granularities help in its minimization.

Numerical Relay Protection Coordination Using Simulation Software
The paper presents protection coordination of renewable energy source connected to bilaterally supplied distribution network. Multifunctional numerical relays with the switching equipment, renewable energy source facility and the distribution network have been detail modeled in DIgSILENT Power Factory software. Overcurrent, overvoltage, undervoltage, overfrequency, underfrequency, directional and earth fault functions have been used for protection coordination. The different relay and fuse characteristics have been presented in one time-overcurrent plot. The damage curve and characteristic currents of electrical equipment in the network have been shown to set the relay tripping times and current settings and for a good and thorough protection of the equipment. Protection coordination settings have been checked and verified simulating faults with the real system vaules.

Active Noise Reduction for General Aviation Aircraft Using Conventional Headsets
Active Noise Reduction (ANR) headsets are quite efficient at reducing noise in a cabin of general aviation aircraft, however they are generally bulky, uncomfortable and expensive. If compromise is accepted in terms of achieved lower noise attenuation for passenger, acceptable noise reduction could be achieved using conventional headsets that are much more comfortable, better suitable for listening to the music and could be wireless. In this paper solutions are presented that use synchronized waveform generator where noise canceling waveform is dependent on engine rotational speed and seat position within a cabin of a single engine general aviation aircraft.

Reducing Off-road Vehicle Seat Vibrations Using Pneumatic Active Suspension and Fuzzy Logic Based Controller
This paper describes the capabilities of fuzzy logic based controllers in the process of pneumatic active suspension of a heavy vehicle seat vibrations. The pneumatic active suspension system is introduced to solve conflicting requirements of comfort and handling. The air spring is used as an active element and the damper is used as passive element for reducing vibrations. The usage of the active air spring improves higher passenger comfort by comparison with passive, semi-active and active hydraulic suspension, during long time drives at a very bumpy road. Description of the seat, including its mechanical characteristics, is given in the paper. The mathematical model was created according to the physical setup of the vehicle seat at the testing laboratory. MATLAB and Simulink are used as tools for developing the simulation model of the driver seat. Control system description and implementation to the experimental setup using dSPACE module, is also explained. The SEAT value is used for the validation of control quality. The obtained simulations show that the developed road adaptive suspension controllers provide superior driver's comfort for most difficult types of road.

Comparative Analysis Between Methodologies and Their Software Realizations Applied to Modeling and Simulation of Industrial Thermal Processes
The current paper is dedicated to a comparative analysis of numerical methods used for modeling of thermal processes in electrical devices, namely - high temperature chamber resistant furnaces (HTCRF). In this context the presented analysis aims at comparing developed simulation models based on the finite element method (FEM) and systems of ordinary differential equations (SODE). Different software solutions of the two aforementioned methods are applied, where they are examined in contrast of the usage and handling of computing hardware resources. The applicability and feasibility of the methods is therefore analyzed and compared for different modes of operation of the computing equipment. Additional comparison of the two numerical methods is made against practical experimental results for the same cases. Thus algorithms and recommendation are formulated for optimal practical integration of the numerical methods, models and simulations.

Remote Control of Model Vehicles Using Android Mobile Devices
Embedded systems development started in 1960’s and over the time became the backbone of many academic and industrial projects. With the popularization and by each day wider use of smart mobile devices (smartphones and tablets) arises a new possibility of interfacing the embedded systems – through smart devices. One of the main principles of the smartphone and tablet operating systems is simplicity and accessibility. This component was usually lacking and was a sore throat of the embedded system development. By connecting these two types of devices, we simplify the control and add myriad of new possibilities to the embedded systems while giving smartphone and tablet users control over the external devices. The main goal of this project is to create and build a fully functional model of a remotely controlled boat controllable through a mobile application. Connection is acquired through standard Bluetooth protocol and users are presented with the readings of the sensors found on the model. Boat is controlled by rotating the mobile device around the x and y axes but maintains the ability to slow down or steer away from the obstacles.

Optimal Control of a Family House Heating System
Approximately 42% of total energy usage today is spent on the heating of the human environment. Energy consumption can be significantly reduced by proper design of the heating control system -- performed studies suggest that in average about 12% reduction of energy usage can be achieved based on control system improvement. This paper describes an efficient control of a family house heating system in its very common configuration. We use model predictive control to fully take into account the prediction of disturbances (room temperature), reference values of power per rooms and physical limitations of actuators. This will result in an optimal flow rate and
temperature of heating medium required to meet all the demands. In this paper we will first present the model of a heating system, and from it derive model predictive control and verify it through simulation.

Model Predictive Control of a Heating, Ventilation and Air Conditioning System
The largest energy consuming subsystem in a building is heating, ventilation and air conditioning (HVAC) system. It is thus essential to optimize the behavior of that subsystem in order to achieve energy savings. In this work focus is on efficient energy usage in a sample building zone system consisting of two coupled zones. Ventilation, heating and cooling are done by air handling unit (AHU) and variable air volume boxes (VAV). Optimization of the system means finding optimal control sequences for AHU and VAV boxes. The model of the coupled zones is linear, while the models of the AHU and VAV boxes are nonlinear. In order to find solution that minimizes consumed energy, keeps zones temperatures in given boundaries and respects ventilation requirements, linear programming and linear zones model are used to find appropriate heating/cooling power exertions to zones, and then those power exertions are enforced by a proper control sequence for AHU and VAV boxes.

Tuning of Model Predictive Controller for Wind Turbine Load Reduction
Classical objective of wind turbine control is to maximize the power extracted from wind. However, with the increase in wind turbine size the structural loads become a limiting factor for safe wind turbine operation and wind turbine operating life. In this paper we investigate the design of a model predictive controller that reduces wind turbine loads at the expense of wind turbine power variability. By appropriate tuning of the model predictive controller we show that the trade-off between load reduction and power variations is favorable.

Control of the Grid Side Converter in a Wind Turbine
Due to constantly increasing wind power share in total installed power transmission system operators must adhere to ever stricter grid codes in order to maintain stable, secure and reliable power system operation.
Grid codes require from wind power plants to participate in active and reactive power control and frequency control. In particular, wind power plants need to have fault-ride through capability and must respect grid codes' power quality demands. To satisfy those requirements wind turbines have power electronic devices - converters - as an interface between the wind generator and the grid. A lot of research effort is focused on improvement in the design and control of the grid side converter, which connects the turbine to the grid. This paper presents some of the established grid side converter control strategies. The challenges regarding grid side converter control are also discussed with a brief overview of recent research trends.

A Leader-Follower Approach to Formation Control of Multiple Non-Holonomic Mobile Robots
Many cooperative tasks in real world environments need the robots to maintain some desired formations when moving. Formation control refers to the problem of controlling the relative position and orientation of robots in a group, while allowing the group to move as a whole. In this paper, a novel leader-follower formation control law for multiple non-holonomic mobile robots based on kinematic models and trajectory tracking techniques is proposed.

One Variant of Self-tuning DC Motor Adaptive Controller
This paper proposes a self-tuning adaptive controller in order to produce response of a second order block from the typically nonlinear motor. Periodic reset of controller's estimator block is employed as an improvement of the original design. Classical model of DC motor is well-controlled via this improved controller, while for the system containing a motor and thyristor-fired phase-controlled rectifier a new improvement is introduced, the arcsine compensation block. Controller is tested in different simulation conditions and it shows high ability to compensate any effects, produced either by the reference value change or the external error induced by load or thyristor rectifier.

Primjena zelenog računalstva u podatkovnom centru Rafinerije nafte Rijeka
Rafinerija nafte Rijeka je pokrenula projekt izgradnje informacijskog sustava za podršku procesima proizvodnje MES eng. manufacturing execution systems. Kao nužan preduvjet za uspostavu informacijskoga sustava za podršku procesima proizvodnje bila je izgradnja računalne infrastrukture odnosno podatkovnog centra. Glavni ograničavajući faktor pri projektiranju podatkovnog centra bila je fizička veličina prostorije u koju se uz već postojeću aktivnu komunikacijsku opremu trebala smjestiti nova računalna infrastruktura koristeći pritom standarde TIA-942, TIA-607 i IEEE 1100 standarde. Usvojen je prijedlog za korištenjem na tržištu dostupnih tehnologija koje su nudile istovremeno veoma visoku dostupnost, fleksibilnost, modularnost, optimizirano iskorištenje računalnih resursa i fizičkog prostora, centralizirano upravljanje a sve zajedno su poznate pod zajedničkim nazivnikom zeleno računalstvo eng. green computing. Izabrana programska osnovica MES sustava je istovremeno podržavala implementaciju svih elemenata sustava u virtualnoj okolini koji su značajno smanjili investiciju u infrastrukturu podatkovnog centra kao i smanjenu ukupnu potrošnju energije. Prvi pokazatelji ispravno izabrane strategije ogledaju se u implementaciji projekta unutar vremena i planiranih financijskih sredstava te kasnijoj lakoći upravljanja infrastrukturom te skalabilnosti u pravom smislu riječi.

Nadziranje i dijagnostika rada rafinerijskih postrojenja
U industrijskim postrojenjima veliki broj procesnih varijabli potrebno je održavati unutar definiranih granica kako bi postrojenja radila zadovoljavajuće. Nadziranje i dijagnostika procesa imaju ključnu ulogu u osiguranju radnih zadataka postrojenja. Ciljevi su rutinsko praćenje procesa, otkrivanje i dijagnoza kvarova te preventivno nadgledanje. Procesne varijable se tradicionalno nadziru jednostavnim metodama praćenja granica varijabli i analizom djelovanja procesa. Statističko vođenje procesa temelji se na kontrolnim grafovima, a koristi se za praćenje kvalitete proizvoda i slične primjene gdje su periodi uzorkovanja dugački u odnosu na dinamiku procesa. U novije vrijeme sustavi za vođenje procesa postaju ključna komponenata za cjelokupni nadzor procesnog postrojenja. Viševeličinske metode omogućavaju bitna poboljšanja nad tradicionalnim metodama u slučajevima kad su mjerene varijable visoko korelirane. Također, suvremeni softverski alati za nadzor i optimiranje rada regulacijskih krugova omogućuju rad procesa u optimalnim uvjetima. Ovim radom prikazana je analiza rada procesa i optimiranje djelovanja regulacijskih krugova na primjeru procesnog postrojenja Rafinerije nafte Rijeka uz primjenu suvremenih metoda i softverskih paketa visoke razine. Kao rezultat dana je statistička analiza rada regulacijskih krugova i optimiranje vođenja industrijskog procesa.

Primjena Microsoft Windows Embedded operativnog sustava na ugrađenim računalnim platformama
Primjena računala za POS (Point of Sale), web kiosk, informacijske panele, navigacijsku primjenu u plovilima i sl. karakterizirane je dominantnim korištenjem samo jedne aplikacije. Ovaj način korištenja donosi globalno znatno smanjuje zahtjeve na složenost programske i hardverske opreme računala, ali ovisno o primjenu računala i programa može donijeti i neke nove specifične zahtjeve. Ovaj rad opisuje primjenu Microsoft Windows Embedded operativnog sustava, modularnog operativnog sustava, prilagođenog radu na računalima male procesorske snage sa specifičnim hardverskim komponentama. Modularnost sustava omogućuje da operativni sustav sadrži samo komponente nužne za konfiguraciju i pokretanje glavne aplikacije ugrađenog računala. Ugrađena računala tradicionalno se baziraju na specifičnim sustavima više cijene temeljenim na Linux operativnim sustavima. Korištenje Windows Embedded operativnog sustava relativno je nova tehnologija koja omogućuje korištenje postojećih Windows aplikacija na ugrađenim računalima.
Sustav se koristi za implementaciju bežičnog pristupa internetu i prikaz plovnih informacija broda/motora na čarter plovilima.

Upotreba mini računala s Linux operativnim sustavom na lokacijama s zahtjevnim uvjetima okoline
Često postoji potreba korištenja računala na lokacijama koje u potpunosti ne zadovoljavaju standardne uvjete okoline (temperatura, vlaga, nečistoće u zraku, udaljenost od ostalih uređaja, ...), a potrebna snaga računala nije kritična. Korištenjem mini računala (mini-ITX) bez mehaničkih pokretnih dijelova s instaliranim Linux operacijskim sustavom koji koristi isključivo RAM memoriju za svoj rad može se dobiti potpuno funkcionalno računalo, koje i u zahtjevnim uvjetima okoline nije potrebno posebno održavati. U ovom radu opisan je strojni i programski dio mini računala, te statistika rada 13 računala u 3-godišnjem razdoblju s 24/7/365 radnim režimom.
