In the European Statistical System (ESS) there are more and more generic information systems (ISs) being developed and implemented for production and dissemination of official statistics (OS) macrodata datasets. These generic systems are based on metadata repositories providing, in return, a whole set of additional functionalities and services for users of the systems. Microdata dissemination, being...
Draft proposal of the Croatian State Information Infrastructure Act was made public in December 2013. This Act, due to be entered into legislative procedure by summer 2014, aims to regulate rights, obligations and responsibilities of the state regulatory bodies concerning establishment, development and management of the state information infrastructure system. The Act adopts a unified method of establishing...
Since their introduction, social media sites (SMSs) such as Facebook, LinkedIn and Twitter have attracted millions of users, many of whom have integrated these sites in their daily practices. As of this writing, there are hundreds of SMSs, with various technological affordances, supporting a wide range of interests and practices. Social media are gaining popularity and are increasingly used in regular...
UNDERSTANDER is an exploratory R&D project investigating Business Intelligence (BI) as a knowledge-gathering tool for supporting innovation processes in specific industrial domains. We develop a knowledge-based model that is grounded on the following three concepts: (i) Business Intelligence Model (BIM) developed by a Canadian project for BI technologies, (ii) taxonomy of Competitive Intelligence...
This paper introduces spend analysis, spend management and supplier management field. It describes the need for a spend analysis system, its' benefits and savings which such system can help to achieve. We present flowchart of spend analysis process in form of a dataflow diagram. We present main issues in development of a spend analysis software, and give an overview of current spend analysis systems.
Discussions of the developments in biometric measures have long recognised not only the increased technological capabilities they offer but also the particular impacts they pose for privacy. However, not unlike the case with other surveillance measures, the relatively narrow scope of this concept of privacy in relation to biometrics fails to take account of other important social impacts emanating...
Availability and increased hardware performance of handheld devices with high resolution screens encourage users to exploit them as the second screen while watching television. Second screen is a term that refers to an additional screen of a handheld device such as a tablet or a smart phone, with an operating system capable of running desired installed applications. Desire to make additional DTV information...
The need for measuring the sound quality in VOIP environment is a basic requirement of modern multimedia communication systems due to technical, commercial and legislative reasons. Measuring the sound quality using objective methods is not standardized up till now. Expected measurement results should be in correlation with subjective tests of sound quality. The usage of application for measurement...
Stochastic Resource Constrained Project Scheduling (SRCPS) is among the hardest combinatorial problems. Exact calculations of interesting measures, such as expected project duration and the probability of satisfying the deadline, using known probabilities are in #P even for relaxed instances of the problem where resource constraints are ignored. The most common approach is to use substantial simulation...
This paper describes properties of graphical presentation of pseudorandom number generator. Numerous more-or-less rigorous tests for randomness are available in the literature, and some of them are presented here. It is shown that both graphical and analytical tests give almost equal results, but graphical tests are simpler and closer to human perception. Because of that properties, visual tests combined...
This paper presents a survey of students' opinions about the integration of e-learning in educational process. The results of how students are informed on distance learning and e-learning are presented. By analyzing the results, data can be obtained which clearly show what steps should be taken in order to implement a new methodology of education, e-learning methodology.
This paper deals with information education in development of a knowledge-based society in Croatia. The basic objective of the paper is focused on systematic comprehension and analysis of the situation related to information education and its tendency. Hence, some concepts and models for IT education in Croatia were propounded. Accordingly, these tasks were fully accomplished. Application of ICT has...
The knowledge acquisition of basic logical forms (term, statement, conclusion, and proof) is a prerequisite of the acquisition of any other knowledge and skills. Therefore, the knowledge acquisition of basic logical forms needs to be addressed in the earlier stages of education. In order to support the acquisition of knowledge and skills in the domain of logical forms, the authors of this paper propose...
This paper discusses the place, role and importance of informatics education in contemporary society. The levels of computer science education are analyzed and explained, from elementary computer literacy, which is the basic requirement for the age of knowledge, to the education of professional IT experts. Implementation of computers in education, as a significant factor of educational development...
In this paper we present the architecture of a new Micro Assessment (MA) system for “micro knowledge and skills control” that allows the manager to get information and status on knowledge gained on behalf of the employees, on very short status cuts during the working hours, rather than scheduling special meetings with them in order to assess their gained knowledge. This kind of micro testing saves...
In this paper, inventory management system for water supply network is presented. Considering the existing experience in telecommunications network management area, we have made comparison between basic aspects of telecommunications network management and water supply network management. As a first step, we have detected the need for developing water supply network inventory system, covering configuration...
The modern manycore coprocessors and GPUs demonstrate very high performance on certain problems. Recent research has shown that these coprocessors can be used to accelerate database operations. But, to the best of our knowledge, there is only a little prior work on using coprocessors in multiprocessor database systems. This paper focuses on evaluation of database multiprocessor architectures with...
One of the basic requirements when managing moving objects in data stream management systems (DSMS) is visualization of continuous queries results on the map. In most cases, the result of a continuous query is data stream whose elements contains information about locations of moving objects so that we are talking about visualization of streaming trajectories. Such visualization involves redrawing...
Quality of Service in communication networks is a request for minimal required performance needed for transferring IP packets in a network. The performance can be ensured with a set of mechanisms that guarantee required performance through shaping and policing of packet traffic. Their goal is to prevent congestion, packet delays and packet loss. The goal of this paper is to introduce some of the commonly...
We define a new non-sequential logic element: the random flip-flop. By definition it operates similarly to the conventional flip-flop except that its clock input functions with probability of 1/2 otherwise the flip-flop does nothing. We discuss several applications of that novel device.
