Implementation of revised ePrivacy Directive rules on accessing, and using information stored in users' terminal equipment was due in 2011 throughout the EU. Corresponding rules were already in 2011 transposed into Croatian law. In this paper authors analyze new ePrivacy Directive rules while focusing on cookies and similar technologies. They examine interpretations of compliance requirements as to...
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 zone system consisting of two coupled zones. Ventilation, heating and cooling are done by air handling unit (AHU) and variable...
The paper presents an informal specification of a software product dedicated to manufacturing execution functions in long products hot rolling mill application field. The product is an implementation of so-called Level 3 functions of a CIM pyramid model. The main functional groups of the product are discussed, as well as principal features are described.
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...
The 4w project has demonstrated the feasibility of a prospective memory support systems based on a mobile client and an ontology based server side reasoning engine. However, the experiments also showed that the level of efficiency of the system was largely dependent on the precision and richness of the ontology used to autonomously identify the places where users may efficiently perform their tasks...
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...
Colorectal cancer is one of the most common types of cancer worldwide. Assuming increased or decreased gene expression is the reason for abnormal cells work and processes interference in the colorectal region, in our previous work we used data from Illumina microarray technology to analyse gene expression values. Once we have unveiled biomarker genes and developed methodology for Bayesian posterior...
Education and Teacher Training Agency i s a public institution independent regarding its activities and management according to law. It is founded by Republic of Croatia, and seated in Zagreb. Its activities are normalized by Constitution and consider executing professional and advisory acts regarding education, in which an important role plays organizing and conducting training of educational workers...
In the last years measuring functional size of software applications became one of the most popular methods when there is need for creating models for effort, costs and budget estimation in software development. Functional Size Measurement (FSM) methods quantify the software from its user's perspective, disregarding quality and technical criteria. In context of conceptual models where models represent...
Today's CPU cores usually possess private L1 and L2 cache and share L3 cache with other cores of the chip (die). Private or shared cache could have significant impact to the algorithm performance in parallel implementation, i.e. using tightly coupled CPU cores with the same last level L3 cache, or loosely coupled CPU cores with private L3 cache per chip. Private cache increases the overall cache size...
Hundred and seventy-five thousand device-hours of operating life at channel temperatures above 200°C is demonstrated on AlGaN/GaN HEMTs fabricated using GaN-on-diamond technology for the first time. No catastrophic failures and no drain-current drift larger than 10% from turning the devices on were recorded throughout this two-year DC test.
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...
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...
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...
County development strategy is the main strategic document of a county (regional government) in Croatia regulated by the Law on Croatian Regional Development [10]. It is the framework for Activity plan of implementation County development strategy and planning projects and activities, financial plans during a period of three or in the future of seven years. In this article author will present the...
Modern companies, institutions, organizations, individuals, etc. have websites in order to extend their reach to audience or customers. However, it is not sufficient anymore just to have an appearance on web and to be recognized through various web search engines. People are increasingly using smartphones and tablets for accessing the Internet, not just desktop personal computers and notebooks, therefore...
According to the State budget data, around a billion kunas (131.763.000 €) yearly is spent for IT projects in public and state administration in Croatia. Their success is of extreme importance for general development and fulfilment of state goals. Therefore, it is necessary to regulate the areas of preparation, monitoring and management of IT projects through legislation, and define the role of information...
Lifestyle of modern society results in rising need for electric energy. On the other hand, reduction of pollution and increase of energy efficiency leads to integration of renewable energy sources. Dynamic and unpredictable loads make the power system operation a challenging task, which results in lower security margins and large power system blackouts. Therefore, power utilities are collaborating...
Modern power systems are facing increase of overall energy consumption and aging of the main infrastructure. On the other hand, integration of intermittent renewable energy sources and development of the energy market are introducing uncertainties and strains to the power system operation, which is closer to stability limits. As a consequence, large power system blackouts occur. Synchronized phasor...
Cloud computing is not just a buzz-word, it represents a strong direction of IT industry development. Speaking of cloud computing we should distinguish three different service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The scope of this work is a model of Software as a Service. This represents the lease of computing resources on a network...
