Tuning Electronic Properties of Molybdenum Disulfide by a Substitution in Metal Sublattice 
The electronic properties of molybdenum disulfide have been modified by substitution of molybdenum atoms with non-isovalent Re and Nb atoms. Similar approach results in preparation of semiconducting Mo1-xRexS2 and semimetallic Mo1-xNbxS2 materials. These solid solutions were exfoliated in organic solvents. Nano size colloidal dispersions were used for preparation of thin films. All materials are characterized by a set of modern methods.

Alternating Current Electrochemical Anodisation of Silicon on Insulator Layers
Porous silicon (PSi) samples were prepared by electrochemical anodisation of silicon on insulator layers. Structural and optical properties of prepared samples were investigated by Raman and photoluminescence (PL) spectroscopy and field emission scanning electron microscopy (FE-SEM). The anodisation of silicon on insulator layers was performed by alternating currents (AC) of the mains frequency of 50 Hz. A very intensive PL was observed at the circular edge of the samples that exhibited micrometer sized island-like porous structure, while the central part of the samples showed moderate PL signal. The formation of such porous island-like structures with strong intensity PL was interpreted with stress induced due to difference of the piezoelectric coefficient of silicon and quartz layers (buried SiO2). Micro-Raman spectra of islands show strong phonon confinement with the cluster size between 1.4 and 3.5 nm.

Porous Silicon Prepared from p- and p++ Bulk Silicon
Macro and meso-porous silicon (PSi) samples were prepared by electrochemical anodisation of p- and p++ doped silicon wafers in hydrofluoric acid (HF) based electrolyte under galvanostatic conditions. Anodisation time and current were varied in order to obtain different PSi morphologies. Samples were characterized by scanning electron microscopy (SEM), photoluminescence (PL) spectroscopy and Raman spectroscopy. Samples prepared on p- type substrates were macro-porous, showed visible photoluminescence and no observable phonon confinement in Raman spectrum. Porous silicon prepared on p++ type substrates was mesoporous, showed no observable photoluminescence and intense phonon confinement was observed in their Raman spectra. Silicon nanocrystal dimensions in PSi samples obtained from photoluminescence and phonon confinement models were correlated with silicon electrochemical dissolution valence nd. A surface morphology instability is identified in case where electrolyte is more conductive than the silicon substrate.

Some Physical Problems in the Preparation and Analysis of the Heavily Boron and Phosphorous Doped Polysilicon Thin Films
Abstract – We discuss problems of obtaining and analyzing solid solution phase in the case of phosphorus and boron doped polycrystalline silicon. We show that the problem of determination of the current carrier concentration is not yet solved especially in the heavily doped regime. There are described some currently used methods and the ways of preparation heavily doped polysilicon thin films. According to the performed previous discussions, we suggest the method and the way of preparation of the phosphorus doped silicon thin film samples with the best ratio of the carrier concentration to the dopant concentration. The characterisation and the investigation of the stability of such obtained samples are presented.

Luminescence, Raman and Synchrotron XPS Study of Amorphous Ge2S3 Based Films
Ge2S3-based films have been investigated using Raman, photoluminescence and photoemission spectroscopy. For the sake of comparison some of the photoluminescent properties of bulk glasses have been used. The synchrotron photoelectron spectroscopy (SRPES) and XPS spectra of a-Ge2S3 films have been measured after the illumination and annealing. The changes in the parameters of the film’s core levels induced by near or above band gap light and thermal treatment are discussed in the paper. We consider the possibility that the PL radiation in Ge2S3-based films is a surface contaminant effect from native oxidized layer, which might have formed in the air.

Light Coupling Between the Whispering Gallery Modes of a Coated Microsphere and a Tapered Fiber
Spherical microresonators were coated using a 70% SiO2 – 30% HfO2 glass doped with 0.3 mol% Er3+. The sphere was characterized by coupling a 1480 nm pump laser inside the sphere using a tapered optical fiber and observing the 1530-1580 nm Er3+ emission outcoupled with the same tapered fiber. The measurements were done for different coating thicknesses and compared with theoretical calculations to understand the relationship of the detected signal with the whispering gallery mode electric field profiles.

Eu3+/ Yb3+ - Activated Nanocrystals of Lanthanide Phosphates
The paper presents structural and luminescence studies of two lanthanide phosphate composites codoped with different concentrations of Eu3+ and Yb3+ ions. The powders of polycrystalline phosphates were synthesized by the modified Pechini method. The composition and morphology of the samples were characterized using inductively coupled plasma atomic emission spectrometry and transmission electron microscope. The crystal structures of the powders were obtained from the powder diffraction data and were refined using the Rietveld method showing the existence of two or three phases in the materials. The absorption, excitation, and emission spectra of the phosphates have been studied. The upconversion luminescence has been observed in the Eu3+/Yb3+-doped samples and the energy transfer processes were discussed.

Numerical Study and Performance Analysis of Carbone Nanotube Field Effect Transistors
As transistors are scaled down to nanometers, the theory and structure of nanometers devices such as carbon nanotubes field effect transistors (CNTFET) are being extensively studied. Self consistent solution of the Poisson and Schrödinger equations is performed using the non-equilibrium Green’s function (NEGF) formalism to investigate the impact of nanotube diameter, gate oxide thickness and high-k gate dielectric permittivity parameters on the coaxially gate, n-type CNTFET. Our results show that the nanotube diameter and gate oxide thickness influences the ION/IOFF current ratio, the drain induced barrier lowering (DIBL), the subthreshold slop as well as transconductance and drain conductance. Furthermore, in this work we focus on the impact of high-k gate dielectric permittivity on the performance of CNTFETs. Using high-k dielectric is caused by the enhancement in device characteristics. A good agreement with numerical simulation results is obtained.

New Silicon Reach-Through Avalanche Photodiodes with Enhanced Sensitivity in the DUV/UV Wavelength Range
Many applications, particularly in the medical and bio-medical fields, require highly sensitive detectors in the short wavelength range (blue and below); so far there have been few commercially available avalanche photodetectors with adequate performance to satisfy demands of such applications. We have developed a new silicon reach-through avalanche photodiode (RAPD) operating in the blue wavelength range with improved sensitivity and noise performance superior to any similar detectors available on the market today. This has been accomplished thanks to an innovative, ultra-thin and highly doped surface top layer grown using a new epitaxial technique developed at Delft University of Technology in The Netherlands. An important additional advantage of this new RAPD is its unmatched noise performance over the widest commercially available wavelength range from 250 nm to 1100 nm. Short wavelength response is limited only by the transmission of the package window optimized for wavelengths starting at 250 nm and up, but devices can operate at wavelength even below 100 nm if assembled in a vacuum.

Low Power CMOS Sub-Threshold Circuits
Emerging new applications, such as wireless sensor nodes powered by energy harvesters, demand the change of the circuit design paradigm. Namely, for the past years, designers aimed at the minimum delay point in the energy-delay space, while the aforementioned applications require that the minimum energy point becomes the priority. One of the ways to achieve low energy consumption, while neglecting performance, is to operate the transistor in the sub-threshold (weak inversion) operation region. Since CMOS is the most widely accepted circuit design methodology, it would be the easiest and the most cost-effective to use it to design sub-threshold digital circuits. In this paper we provide an overview of subthreshold CMOS digital logic circuits possibilities and limitations. We show that the same topology can be used, just as in strong inversion operation region. It is also shown that, comparing to the standard CMOS inverter, the speed and the temperature characteristic of the CMOS inverter with the dynamic threshold in the sub-threshold operation region is better.

High-Order Inductorless Elliptic Filter with Reduced Number of Capacitors Using Signal-Flow Graphs
In this paper a method of realizing seventh-order elliptic filter using signal-flow graphs is presented. The elliptic filter having a minimum number of capacitors is compared with the filter having a higher number of capacitors. The version with minimum number of capacitors provides area savings in IC form. Both filters (i.e. filter with minimum and one with higher number of capacitors) have a low sensitivity to component tolerances according to Orchard’s theorem. The seventh-order elliptic filter has three parallel capacitors forming three parallel tanks, and therefore has three finite elliptic transfer-function zeros. The realizations of one and two parallel capacitors have already been presented elsewhere. The sfg derivations necessary to realize seventh-order filter having additional resistive network is presented, which is very complicated in the case of three zeros. Transfer function magnitudes are simulated using the PSpice program. Monte Carlo runs confirm the low sensitivity to component tolerances of both circuit types.

Engineering Education: Where We Are and Where We Go from Here
While MOOC-s (massively open on-line courses) are getting a lot of attention in the press, many other interesting developments have been happening in the field of engineering education. It can be argued that many of the problems, perceived or real, have had solutions for quite some time and that problem is not in the development of new, effective and efficient instructional techniques but that the problem lies in the implementation of the known techniques. This paper will attempt to briefly summarize the current state of engineering education in the US, perceived problems, and potential solutions. As an example of what can be accomplished by a switch to more research-based instructional strategies we will discuss our experience in introducing active learning technique in microwave circuit design course. It is hoped that this will in some small way contribute to the discussion on the direction of engineering education in Croatia.

Concept for a SIL3 Middleware Encapsulating Safety-Related Aspects of Applications for an 8051-Based SIL3 Multi-Core System-on-Chip
In this paper, a concept for a SIL3 middleware implementing safety-related aspects is proposed. The middleware is intended to be used by applications that are written for a recently developed safety system-on-chip. Each module implements a low-level driver. Each driver represents a specific functionality of the system-on-chip. Once being certified conforming to IEC 61508, the middleware would enable writing safety-related applications aimed at SIL3 almost as straightforward as non-safety-related applications. A multi-core SIL3 architecture for safety-related applications is explained. In addition, possible issues that can arise during the software development are identified. Furthermore, conformance arguments on meeting SIL3 are depicted.

Validation of a SIL3 Middleware for Safety-Related System-on-Chips
The aim is reducing IEC 61508 certification effort for safety-related applications. Therefore, an object-oriented middleware has been implemented which, once being SIL3-certified, would allow transferring safety-related aspects from the application into an already-certified code layer. Safety-related applications using this middleware then could be written as straightforward as non-safety-related code. The SIL3 middleware is designed for an 8051-based microcontroller. Because of the 8-bit CPU architecture, several limitations have been encountered. These issues are explained in this paper, and solutions are proposed. The middleware will be used on the multi-more safety chip. SIL3 certified multi-core architecture for safety-related applications is described. Also, the SIL3 middleware architecture is given. The middleware is modular. Therefore, if the user does not want to use some modules they will not be included and code footprint will be smaller. In the SIL3 middleware numerous design patterns can be found. Patterns description and purpose are explained. The pseudo code for the singleton pattern is shown. Moreover, module implementation is depicted. The validation of the middleware is presented and the V-model for the middleware is provided. It conforms to the IEC 61508.

Weighted Least-Squares Design of Sharpened CIC Filters
Efficient multiplierless decimation filter is the cascaded-integrator-comb (CIC) filter. However, in many applications its magnitude response does not meet the requirement for selectivity. One technique for improving the response is sharpening. This technique results in filters having very low passband droop and high folding-band attenuations. The sharpening was first proposed by Kaiser and Hamming. They presented the polynomial amplitudechange function that is obtained by imposing flatness at the points (0,0) and (1,1). In this paper, we present a method for the design of sharpened CIC filters which is based on weighted least-squares error criterion. The method is given in a closed form which provides the optimum polynomial coefficients analytically. The filters presented are suitable for application in narrowband and wideband software radio receivers.

Some Improvements of the Gaussian Elimination Method for Solving Simultaneous Linear Equations
Although it is known that Gaussian elimination method for solving simultaneous linear equations is not asymptotically optimal, it is still one of the most useful methods for solving systems of moderate size. This paper proposes some ideas how to speed-up the standard method. First, the trick which takes the advantage of the eventual symmetry of the system is presented, which speeds up the calculation by the factor slightly less than 2. Second, it is shown that by using some rearrangement of the calculation, it is possible to get additional speed-up, no matter whether the system is symmetric or not, although the eventual symmetry additionally doubles the execution speed. This rearrangement is performed using similar approach as in LU factorization, but retaining basic features of the Gaussian elimination method, like producing the triangular form of the system. As the required modifications in the original method are quite simple, the improved method may be used in all engineering applications where the original Gaussian elimination is used.

LED Powered Identification Tag – Energy Harvesting and Power Consumption Optimization
This paper presents an ID tag concept which is LED powered. The photovoltaic effect of the LED array is used to harvest energy from ambient light or from light source in reader device in order to power the tag. Harvested energy is stored in a capacitor that is used to supply ID tag logic which transmits ID information using one diode of LED array which is also used for powering. The powering circuit, i.e. LED energy harvester is tested for various commercially available LEDs, to determine the most suitable LED type with respect voltage gain and current drivability. The power consumption of presented LED ID tag is optimized using Response Surface Methodology with respect to the following input parameters: frequency of operation, frequency of data transmission and the data packet length with respect to the consumed power and the transmission distance. The optimization proposes optimal input parameters for minimum power consumption and maximum operating distance, presenting a compromise between the aforementioned parameters in reference to the input variables.

Self Powered Current Acquisition System with Wireless Data Transfer
This paper presents a smart energy meter that incorporates a specialized current acquisition system that allows a series of remote stations to measure the current for different consumers and send data wirelessly to a central station that calculates the consumed energy and indicates the contribution of each device. The advantage of the proposed structure is that it allows remote stations to be powered by the current probe, used for measurements. This omits the need of an auxiliary power supply. The suggested technique uses a capacitive tank charged by the current probe – for a fixed voltage the charging time will be proportional to the magnitude of the current and the capacitance of the tank. This charge is then used to power a wireless system, transmitting only the address of the remote station - the tank is discharged afterwards and the process is repeated. The central station then calculates the current of each remote station based on the known size of the capacitive tank and the time between receiving each individual address. The energy is calculated based on the acquired current and the voltage measured at the central station. The suggested system is tested in simulation and experimentally, where it proves functional.

The goal is to present a new solution based on a microcontroller embedded system with power electronic converters. By using the proposed system are solved some of the problems, frequently occurring when low frequency power transformer is used - uneven distribution of the temperature inside the furnace and shorter life of the heating elements. Additional features like direct readout of the supplied voltage, current and power, set and actual temperature, computer interface and others can be easily realized.

Končar Smart Metering - Innovative Solutions for Well Known Problems
EU climate and energy package and Energy Efficiency Plan 2011 has set very ambitious goals for all the Member States regarding Smart Metering (SM). In Croatia, different infrastructural problems and lack of independent regulating body allowed only partial solutions by each utility. On the technical level rollouts were slugged by lack of fully multifunctional solutions with minimal installation and maintenance costs, able to adapt to different meter producers with multiple access to the same data. Končar made strategic efforts to overcome these obstacles trough an integrated R&D approach. Realized solution Končar AMI described in this paper relies on the optimized network architecture with innovative long range and short range wireless communication solutions and modular communication equipment. Such a novel approach allows great flexibility, excellent network coverage, good signal propagation and easy installation process with reliable data transfer with minimum operating expenditures. Combined with a cloud based MDM solution they make the milestones for a powerful and highly adaptable, integrated Smart metering solution that could bring numerous advantages to final users and short ROI. Končar AMI was tested trough a number of pilot projects and proved a concept particularly appropriate for bigger SM rollouts.

Micropositioning Mechatronics System Based on FPGA Architecture
In this paper a micropositioning mechatronics system is conceived and described. Its mechanical design is optimized in order to achieve high precision displacements. High speed closed-loop feedback control is obtained by using both PID and ramp control algorithms programmed as virtual instruments (VI) on an FPGA (Field Programmable Gate Array) module. User controls are programmed in an independent Host VI. A Linear Variable Differential Transformer (LVDT) is employed as a position feedback sensor, while positioning accuracy and repeatability are experimentally assessed by using a Michelson-type laser Doppler interferometric system. Different experiments with point-to-point positioning are conducted. In the first set of experiments, positioning with 100 µm steps is performed. In a second step, 10 mm positioning experiments are done. The system shows a marked nonlinearity when longer positioning steps are used; this nonlinearity influences significantly the output error. It is hence found that the main contribution to system's nonlinearity is caused by the LVDT. The error is compensated via system linearization by an experimentally obtained analytical function which is programmed in the LabVIEW Host VI. Positioning accuracy and repeatability are finally assessed experimentally again and true micrometric positioning is achieved.

On-Water Measurement and Analysis System for Estimating Kayak Paddlers’ Performance
In recent years, the use of computerized measurement systems to help coaching professional kayak paddlers has become rather common. Note that it is not possible to evaluate the quality of the paddling exactly, however the measured inertial signals can provide useful quantitative information. Therefore, it is a challenge to find really good indicators that could help the trainers. Keeping these in mind we have developed a microcontroller-based expandable system that can record the kayak’s motion accurately using the built-in 3-axis accelerometers, gyroscopes and various optional sensors. Several hours of paddling can be recorded and the off-line analysis can be done using a PC. After examining many athletes with different age and technical skills at training and races, we have evaluated the commonly used indicators and defined useful additional indicators based on the statistics and fluctuations of the parameters obtained with peak search algorithms and frequency–domain analysis.

Interpretation of Pulmonary Function Test Results in Relation to Asthma Classification Using Integrated Software Suite
Asthma is a disorder characterized by chronic airway inflammation, airway hypersensitivity to a variety of stimuli, and airway obstruction that is at least partially reversible. To make correct diagnosis of asthma, diagnosis must be based on typical symptoms of asthma and identification of airway hyper responsiveness (AHR) or variable airway obstruction. In some cases, additionally we need to use bronchial provocation test using nonspecific stimuli, such as methacholine or histamine, what is useful for the determination of AHR. However, it is somewhat invasive in nature and it is not available in primary-care clinics or even in many general hospitals. Bronchodilator response (BDR) to short-acting β2-agonists is a valuable test to evaluate variable airway obstruction, which is only useful in patients with reduced lung function at the time of visit.
Developed integrated software suite is user freindly tool which consists all this parameters to assist clinicians in the analysis and interpretation of pulmonary function tests data to better detect, diagnose, and treat asthma conditions.
A total sum of 72 patient reports with previously diagnosed asthma by clinicians was tested with this tool. Even in 65 cases (90.27%) the software has performed the classification of asthma in the same way as doctors.
