Nikolovski (Elektrotehnički fakultet Osijek, Osijek, Croatia) Anfis as a Method for Determinating MPPT in the Photovoltaic System Simulated in Matlab/Simulink  Photovoltaic systems as part of a larger distributed systems for the production of electricity have a non-linear current-voltage characteristics. These characteristics depend on the temperature of the solar cells and insolation of panels. The method known as the search for maximum power or MPPT is widely known, and there are many offered algorithm solutions. The aim of this paper is to present ANFIS (Adaptive Neural Fuzzy System Inference) as a method of computer intelligence in the search function of maximum power or maximum utilization of the PV system, without prior knowledge of the system. MPPT ANFIS will be located between the PV panels and devices for voltage regulation. Inputs used to go inside the fuzzy regulator and outputs of the Fuzzy regulators are going into change power device. The advantage of this method is the low cost of implementation because it uses a embedded computer systems, does not require any additional sensors measuring temperature and insolation and very easy to upgrade in the case of increasing the knowledge base on which is based FIS membership function. Everything is simulated by Matlab / Simulink software on the three-phase IBC system. 2. K. Obarcanin, R. Ostojic (DV Power, Stockholm, Lidingö, Sweden) Linear Motion Calculation of the High Voltage Circuit Breaker Contacts Using Rotary Motion Measurement with Nonlinear Transfer Function  Measurement of the motion of the contact system of high voltage circuit breakers is of crucial importance for assessing the condition and health of the test object. To monitor motion of the contact system, depending of the construction, motion transducer is usually mounted on the moving parts of the linkage of the operating mechanism what introduce a measurement error in the result. This paper presents the method and the software implementation of the mathematical correction of the measurement error. 3. J. Soini, P. Sillberg, P. Rantanen (Tampere University of Technology, Pori, Finland), J. Nummela (Riffid Oy, Rauma, Finland) Portable Sensor System for Reliable Condition Measurement  Regarding sustainable development, there is a growing need for receiving more and more kinds of measurement, space, and consumption information about property. The necessity for property condition measurement is apparent and the appropriate conditions, such as indoor air quality and fitting suitable temperature, have an essential influence on comfort and welfare at work, and at the same time, significance in terms of energy efficiency. This paper presents a portable prototype system for reliable condition measurement. The objective was to generate a reliable portable system that presents measurement data clearly for the monitoring of changes in conditions. This paper describes a prototype system developed for this purpose, which is portable, and improves the quality and also the visual presentation of the collected data. The paper presents elements of the system developed for this aim and also the technology deployed along with its operational principles. It also presents the results of the system application and piloting in a concrete environment, where particular focus was placed on both controlling energy efficiency and well-being at work. 4. F. Marić, I. Jurin, I. Marković, Z. Kalafatić, I. Petrović (University of Zagreb, Faculty of Electrical Engineering and Computing, Zagreb, Croatia) Robot Arm Teleoperation via RGBD Sensor Palm Tracking  In this paper we present a simple and intuitive approach to teleoperating a 3 or higher degrees-of-freedom (DOF) robotic arm in Cartesian space. Using an RGBD camera, we retrieve the position of the user's palm. This position is then translated into the desired robotic arm position, which is then used as an input to a control loop. The entire system is implemented in the Robotic Operating System, enabling simple functionality transfer to any compatible robotic arm. The system was tested on the Kinova Jaco 6DOF robotic arm with the aim of using it for object manipulation. We use the inverse kinematics for calculating the joint rotation velocities required for following the Cartesian path of the human hand. The resulting joint velocities are then sent to the robotic arm control interface which then passes commands to the pertaining API. Results corroborate the validity of the proposed approach for robotic arm teleoperation, opening the possibility for many potential applications. 5. I. Tikvić, G. Vujisić, M. Fruk (University of Applied Sciences Zagreb, Zagreb, Croatia) Control of Thermal Process with Simulink and NI USB-6211 in Real Time  This paper describes method for control and regulation of small chamber heating thermal process using the acquisition card NI USB-6211 and MATLAB Simulink in real time. It will also point out the problems that have arisen in the process of testing the card, a description of the necessary steps which allow the card to work with Simulink and results obtained by testing. 10:45 AM - 11:00 AM Break  6. S. Ulyanov, N. Maksimkin (Matrosov Institute for System Dynamics and Control Theory of Siberian Branch of Russian Academy of , Irkutsk, Russian Federation) Stabilization of Multi-AUV Formation with Digital Control  Formation stability problem for a team of autonomous underwater vehicles (AUV) with digital control is investigated. A leader-follower formation control algorithm for multi-AUV system is proposed. Control signal for the follower that is piecewise constant is computed on the basis of discrete measurements of distance and bearing angle to the leader. An observer for estimation of the time rate of change of the distance and bearing angle are used to improve the control performance. The parameters of the controller and observer are synthesized using a digital control system design method based on the vector Lyapunov functions that allows one to take into account the uncertainties of the plant, measurement errors, and control constraints. Numerical simulations were carried out to demonstrate the effectiveness of the proposed control scheme. 7. M. Kenzin, I. Bychkov, N. Maksimkin (Matrosov Institute for System Dynamics and Control Theory of Siberian Branch of Russian Academy of S, Irkutsk, Russian Federation) A Hybrid Approach to Solve the Dynamic Patrol Routing Problem for Group of Underwater Robots  We suggest an approach to solve the dynamic patrolling problem as the variation of periodic vehicle routing problem with time windows. In order to do this, firstly a set of waypoints (customers) should be located in space in such way that their spherical neighborhoods, which corresponds to the size of the robots vision/detections fields, would form a complete coverage of the protected perimeter. Regular inspections of each waypoint by robots of the group not less than once during specified period would guarantee the effective perimeter patrolling. Thus, the routing problem is to a feasible group route ensuring well-timed inspections for all waypoints of the mission. To solve the described problem we propose a hybrid approach, based on the combined use of genetic algorithms and methods and heuristics of local search. The proposed approach allows robots to effectively generate required solutions under given constraints and quickly readjust it in unforeseen situations due to the dynamic nature of the problem. A software modeling system implementing all the necessary computational procedures has been developed; the results of computations are given. 8. A. Smrke (msx, Domžale, Slovenia) Multi - Heater Induction Heating System with Sandwich Material Heater  Induction heater is often used in process of cooking in the household. Advantages is very quick and energy efficient heating of food. In standard cooking appliances heater are placed below the glass surface and they are energy controlled with electronic regulation. Each induction coil is powered with one power board. The power is normal around 2000 W. In case of 4 heaters the max Power is 8000 W. Power regulation is not precise and user can very rear find the right level of energy in different processes of cooking. It was a need to reduce max power and regulation. A new optimal multi heater system is developed. On one power board are connected more induction coils and new electronic board is developed with temperature control. Multi heater system is presented in this article, together with some results of applied multi heater system in real cooking. Glass surface of cooker is replaced with new sandwich material Stainless steel – aluminium – stainless steel. Temperature sensor are developed with hybrid technology and printed on the surface. A new step forward in induction cooker is integration of hybrid heater with power max 100W and temperature max 125 0C is implemented on top of induction coil. Developed is Control algorithm based on needed cooking process, where very little power is needed in process of cooking after food is heated to boil. Such algorithm enables the use of cooker with maximum power 2000 W for cooker with 4 coils and very precise automatic cooking control. Software and hardware are explained in article. Results of test are done with thermodynamically analysis of real cooking process. 9. I. Astrov (Tallinn University of Technology, Tallinn, Estonia) Two-Rate Motion Control of VTAV by NARMA-L2 Controller for Enhanced Situational Awareness  This paper focuses on a critical component of the situational awareness (SA), the motion control of autonomous vertical flight for vectored thrust aerial vehicle (VTAV). With the SA strategy, we proposed a two-rate flight control procedure using two autonomous control subsystems to address the dynamics variation and performance requirement difference in initial and final stages of flight trajectory for a nontrivial VTAV type mini-aircraft model. This control strategy with using of NARMA-L2 neurocontroller for chosen model of VTAV has been verified by simulation of take-off and forward maneuvers using software package Simulink and demonstrated good performance for fast stabilization of motors, consequently, fast SA with economy in energy can be asserted during search-and-rescue operations. 10. T. Špoljarić (University of Applied Sciences, Zagreb, Croatia), M. Špoljarić (Frigo-Ing d.o.o., Kašina, Croatia) LADDER Program Solution for Multi-probe Monitoring and Control in Simple Cooling Process  Simple cooling process is a thermal process that usually takes place in industrial refrigeration systems used for storage of different types of goods. This type of process is based on control that usually uses one or two temperature probes for temperature reference. It is also a static process that consists mostly of two repeating cycles: one of refrigeration and one of defrost. Multi-probe control uses more than two temperature probes set in different areas of a cold room. In this type of control temperature reference can be calculated via mean value algorithms with different weight factors attached to different probes. This type of control can be used in storage of sensitive goods since the accuracy of temperature measurement is greatly increased with number of probes. 11. M. Shopov (Technical University of Sofia, branch Plovdiv, Plovdiv, Bulgaria) An M2M Solution for Smart Metering in Electrical Power Systems  The paper presents an implementation of smart metering application in electrical power systems. It makes uses of cloud computing and M2M technologies. The use of cloud computing technologies increase reliability and protection of collected data and eases the software developers in management of remote devices – the actual devices are managed through web services and provided REST-based interfaces. The smart meter is based on PST power transducer developed at the Technical University of Sofia, an embedded platform A20-Olinuxino and DeviceHive - an M2M platform running on a private virtual infrastructure. 12. D. Miljković (Hrvatska elektroprivreda d.d., Zagreb, Croatia) Noise within a Data Center  Data centers with its numerous servers, network switches, routers and air conditioning equipment produce significant noise that influences work and communication of maintenance staff. Noise levels and spectrum within a data center are measured and analyzed. Daily and weekly variations of noise levels are also captured. From measured noise levels and spectrum speech intelligibility measures are calculated and communication distances within a data center are determined. The need for noise protection and methods for noise reduction are considered. 13. N. Frid, D. Ivošević, V. Sruk (University of Zagreb, Faculty of Electrical Engineering and Computing, Zagreb, Croatia) Performance Estimation in Heterogeneous MPSoC Based on Elementary Operation Cost  Effective use of resources available on heterogeneous MPSoC platforms can only be achieved through careful resource allocation and scheduling. The diversity of processing and memory elements will manifest itself in the total time and resources required to perform a task or execute an application. Choosing the right platform element is the key and the first step is performance estimation. This paper tackles the issue of finding the most suitable processing element for each part of the software application through a novel approach – elementary operation cost. The cost of each elementary operation is experimentally determined through a set of carefully devised benchmarks and is used for estimating duration of complex functions found in common applications such as JPEG, AES etc. By raising the abstraction level on which the execution time is calculated from instruction to operation level, common problems in performance estimation such as pipelining and branch prediction can be avoided and estimation accuracy is improved.

S. Vrhovec (University of Maribor, Ljubljana, Slovenia) Responding to Stakeholders’ Resistance to Change in Software Projects – A Literature Review  Software project success rates are gradually improving over the last few years. However, this does not apply to large software projects as only 10 percent are successful. One of the most prominent reasons for high failure rates is resistance to change. Resistance has been studied for almost seven decades however a simple answer to this issue that has been present practically since the beginning simply does not exist. In this paper, we present a review of research on resistance to change. First, we define resistance to change and present its characteristics. Next, we deal with diagnosing resistance as its root causes are often hidden in the complex inter-human relationships and cannot be identified easily. Finally, we present how to deal with resistance to change. Project managers often use a general method for dealing with resistance, such as user participation. When resistance actually manifests itself there is most often no response to it at all. Blindly following an universal general method for lowering resistance is not efficient as methods need to be adapted to specific situations and address the right root causes. Also, the situation needs to be monitored and responses prepared in case resistance manifests itself, persists or increases during the project. 2. T. Lugarić (Creative Fields, Zagreb, Croatia), Z. Pavlić, D. Škvorc (Fakultet elektrotehnike i računarstva, Zagreb, Croatia) Object-Oriented Programming Model for Synthesis of Domain-Specific Application Development Environment  Domain-specific languages are becoming increasingly popular allowing experts to focus on solving their specific problems instead of focusing on the means needed. Various domain-specific tools have been developed that allow experts to design systems and workflows by connecting various graphical elements together. These elements have to either be predefined by a developer, or created by the expert by combining simpler objects together. The issue of bridging the gap between the semantics of the problem and the technology used to implement the solution therefore stays with the software developer. In this article, we propose an enhancement of the object oriented programming paradigm that is aimed at easier conversion of the technology (objects, classes…) into their visual representation. We propose a high-level code-to-graphic compiler that is able to automatically generate domain-specific graphical representations of available technical components. The compiler is designed as a general-purpose domain-agnostic agent, which generates appropriate domain-specific representations of the technology using technical data obtained from the system and domain-specific data provided as a set of rules. This paper discusses the requirements placed on the architecture of the input system, the design requirements for the domain-agnostic compiler and the data needed for a complete description of the domain specifics. 3. M. Pighin (University of Udine, Udine, Italy) Logistic and Production Computer Systems in Small-Medium Enterprises  This paper presents a survey which describes how small-medium enterprises (SMEs) implement and use their information system with respect to their logistic and production processes. The first part of the study identifies the characteristics of the companies and detects their general attitude towards information technology (IT). The second part propose a list of detailed logistic and production processes to analyze the structure and workflow of companies. For each process, if it is present, the company indicates whether it is supported by electronic means and, in the event, the information system adopted, according to three categories: ERP system, office automation, specific developed system. The processes are grouped in ten macro-areas, five for the logistics and five for the production, and the aggregate results of the survey are presented in the paper. The novelty of the study and its interest, both in academic and institutional context as in the real world, resides in the opportunity to evaluate the attitude of SMEs towards information technology in defining, organizing, planning and control their logistic and production processes. 4. B. Zorić, G. Martinović (Faculty of Electrical Engineering, J.J. Strossmayer University of Osijek, Osijek, Croatia), I. Crnković (Chalmers University of Technology, Gothenburg, Sweden) The Implications of Employing Component Based Software Design in Non-Commercial Applications  Software development today is riddled with various challenges, and hangs on the balance of cost and profit. The industry is yearning for shorter times to market without any reduction in quality. Since component based software engineering emerged as a prominent and solid approach to alleviate these challenges, the question remains are there any benefits of employing these paradigms in other areas, excluding commercial applications, such as the area of academic research. This paper considers a different aspect of component oriented design application and demonstrates the implications of its application in research on a pattern classification use case, where the majority of component advantages such as cost reduction or profit maximization do not apply. The presented use case utilizes component based software engineering to build components of a classification system. Feature extraction, classifiers and evaluation procedures are interchangeable components which enable the discussion regarding the benefits of component based development in non-commercial areas of application. 5. J. Krini (Universität Kassel, Kassel, Germany), A. Krini, O. Krini (Robert Bosch Automotive Steering GmbH, Schwäbisch Gmünd, Germany), J. Börcsök (Universität Kassel, Kassel, Germany) Extended Approach to Selecting a Project-specific Reliability Growth Model  The software reliability represents one of the most crucial aspects of functional safety. Software is used in almost any electronic systems. When a safety-critical system is considered, it has to be ensured that the software is able to fulfil the minimum safety requirements. If this is not the case, the software will have to be improved until the minimum requirements are fulfilled. Reliability growth models are used to determine the reliability of software. Depending on the area of application one specific model can deliver better prognosis results than another. This paper serves to introduce a methodology, which is provided for the purpose of selecting the most appropriate model. 5:15 PM - 5:30 PM Break  6. M. Šegvić, K. Krajček Nikolić, E. Ivanjko (Fakultet prometnih znanosti, Zagreb, Croatia) A Proposal for a Fully Distributed Flight Control System Design  Since the delivery of the first A320 airliner with Fly-by-Wire Flight Control System (FCS) in 1988, aircraft avionics architecture evolved significantly. Federated Architecture applied in A320 family of aircraft presumed one computer per function. Limits regarding weight and space availability were reached and new generation of aircraft designed in early 2000s were designed with Distributed Integrated Modular Avionics Architecture consisting of shared hardware resources running separate software modules according to aircraft priorities. Flight Control Computer functions were assumed by Flight Control Module. While reducing the cost, weight and number of computers on board the aircraft, problems with troubleshooting and system modifications emerged. Proving that Critical Systems perform within certain certification safety requirements became infeasible due to unpredictable dependencies between software modules. Abovementioned problems are addressed with a proposal of Fully Distributed Flight Control System Design (FDFCS). Main contribution is that aircraft stability and trajectory control logic is distributed to a network of independent control units (CU) collocated on actuators collaborating to control the aircraft with respect to common goal. This paper outlines design for FDFCS and its CUs. Problems that distributed FCS implies and solves are identified. Finally, requirements for planned FDFCS Hardware in the Loop Simulator are set. 7. M. Saari (Tampere University of Technology, Pori, Finland), A. Baharudin (Keio University, Keio, Japan), P. Sillberg, P. Rantanen, J. Soini (Tampere University of Technology, Pori, Finland) Embedded Linux Controlled Sensor Network  This study utilizes a simple model for constructing sensor nodes – master controller combinations in the Internet of Things (IoT). The model combines hardware and software for embedded systems which measure a predefined set of parameters. The master controller manages several sensor nodes, collects data from them and provides data for clients. The paper introduces a proof-of-concept implementation based on the model. The implementation uses embedded Linux based small computer and microcontroller based sensor nodes in the context of condition measurement, and represents a way to use wireless data transfer between controller and nodes. The target of this study was to test the model, to determine how well a cost-efficient single-board computer could be used to gather sensory data from several sensor nodes, and how this data can be provided for clients over the public Internet. 8. T. Vresk (Končar elektronika i informatika, Zagreb, Croatia), I. Čavrak (University of Zagreb, Faculty of Electrical Engineering and Computing, Zagreb, Croatia) Architecture of an Interoperable IoT Platform Based on Microservices  The vision of the Internet of things enabled the development of a wide spectrum of services, applications and ecosystems, deemed infeasible not long ago. However, lack of standardisation poses a number of questions still requiring proper addressing. Due to the need of supporting large number of users and significant data processing throughput, Internet of things requires a specific approach towards the problem of providing sufficient scalability and performance, clearly pointing towards the distribution of effort among a large number of small and specialised services. Reflecting on the importance of coexistence of heterogeneous systems supporting the Internet of things, this paper presents an overview of the specific problems inherent to the IoT and the proposal of an architecture of the micro service based middleware aimed at connecting heterogeneous IoT devices. The middleware functionality is achieved irrespective of the size and complexity of a given device network, both from the data model aspect and from the aspect of connecting existing and newly created middleware components. 9. D. Miljković (Hrvatska elektroprivreda d.d., Zagreb, Croatia) Active Noise Control: From Analog to Digital – Last 80 Years  Beginnings in the field of active noise control date from 1930s. From these pioneer attempts great deal of progress has been achieved. In this brief review paper advances from simple fixed analog systems, manually adaptive analog systems, acoustic feedback neutralization, fully adaptive digital systems with secondary path modeling and multichannel systems are briefly presented. Applications of active noise control in closed and open space, industrial and automotive applications, as well as active noise canceling headphones and new solutions with smart materials are also briefly mentioned. 6:30 PM - 7:00 PM Papers written in Croatian   1.

Budimirović (HT d.d., Zagreb, Croatia) Sustav za lociranje atmosferskih pražnjenja u identifikaciji kvarova TK mreže uzrokovanih atmosferskim prenaponima  Na korisničkoj terminalnoj opremi koja služi za pružanje tzv. 3play usluge (internet + telefonije + televizija) su česti kvarovi uslijed prenapona uzrokovani atmosferskim pražnjenjima, što ima za posljedicu nezadovoljstvo korisnika te dodatne troškove održavanja. Kvarovi se najčešće događaju u ruralnim sredinama gdje se nalaze nadzemne niskonaponske i telekomunikacijske mreže te u područjima s većim specifičnim otporom tla i većom gustoćom udara munja. U radu je prikazan proračuna induciranih prenapona u telekomunikacijskoj mreži uslijed udara munje. Nadalje, prikazana je korelacija podataka o atmosferskim pražnjenjima s kvarovima/ispadima u TK mreži kroz povezivanje sa sustavom za upravljanje i osiguranje kvalitete širokopojasnih usluga. Prikazanom korelacijom moguće je utjecati na automatiziranje i skraćivanje vremena otklanjanja prijavljenih smetnji i kvarova, povećanje broja slučajeva koji se uspješno rješavaju prilikom prvog poziva, što u konačnici omogućava poboljšanje kvalitete pružanih usluga te povećanje korisničkog zadovoljstva i lojalnosti pružatelju. 2. M. Zmijanac (Combis d.o.o., Zagreb, Croatia) SNUPI - Sustav za nadzor i upravljanje procesima infrastrukture podatkovnog centra  U uvjetima sve veće konkurencije na tržištu potrebno je osigurati maksimalnu raspoloživost sustava, povećati sigurnost i pouzdanost, te istovremeno smanjiti troškove poslovanja, odnosno troškove energije, održavanja i broj zaposlenih u operativnom poslovanju. Navedene zahtjeve moguće je postići automatizacijom i optimizacijom performansi nadziranih infrastrukturnih elemenata pomoću sustava nadzora. Takav sustav ujedno nudi i trenutni vizualni uvid u ispravnost i dostupnost infrastrukture, obavijest o trenutnom operativnom stanju, obavijest o očekivanom problemu (trend), te alarm ukoliko je potrebna trenutna fizička reakcija održavatelja. Kontinuirano prikupljanje podataka o ugrađenom hardveru i instaliranom softveru daje potpuni uvid u imovinu i znatno olakšava optimalno planiranje i korištenje resursa. Upravljanje energijom uz maksimalnu dostupnost infrastrukture i razvoj modularnih standardiziranih modela samo su neki od razloga koji sustav za nadzor i upravljanje procesima infrastrukture čine neizostavnim alatom za poslovanje sve važnijih podatkovnih centara današnjice. Ovaj rad daje jedinstven uvid u osnove i izazove jednog takvog sustava kao integrirane nadzorne i upravljačke platforme, s primjerima i osvrtom na trenutno stanje u Hrvatskoj.
