This keynote will give an overview of the last 30 years of human system interaction and the key elements of human computer interaction (HCI) and its transition from traditional HCI into the frontier of human system interaction (HSI). This leads to the discussion as to why HSI is about digital ecosystems and about the world we live in rather than just ICT. We explain the 5 mega trends, and the emergence...
In automation mechanical units are more and more replaced by electronic components. They contain sensors, actuators and information computing systems. The goal is to achieve higher process and product quality. That means, for example, to increase the performance by implementing more functionality. Systems become interconnected, which causes increased complexity - something that cannot easily be handled...
Fast development of computer programs that use 3D objects as fragments of the user interface, or use 3D to interactively represent huge amounts of data, depends on the reuse of interactive 3D objects. Objects, which have their own behavior and are independent of particular application. To be able to reuse an object it has to be possible to find the one that matches interaction criteria of a particular...
SOC, system on a chip, is an advanced organization of embedded systems. A mobile computing SOC is to integrate a mobile computing control or monitor system into one IC chip. It can supply some functions, which support to handle some business in moving. With a mobile computing SOC, the system will be smaller, reliable, efficient, and consume less power. It can make the life be easier and more convenient...
A conventional wire communication system communicates between powered terminals via a main unit. In this system, the main unit communicates with the powered terminal by changing the voltage signal to the positive and the negative. The powered terminal communicates with the main unit using the reply current signal. Because this system is used for on-off control, the communication speed is slow. Then,...
Currently widespread approaches to implementation of finite state machines in Field Programmable Gate Array circuits consist of separate encoding and mapping steps. This paper presents a graph-based algorithm that implements a symbolic functional decomposition of the FSMs - a method that does not pre-encode the machinepsilas states, but instead encodes them gradually during every step of the functional...
The authors present a multidisciplinary project called PROPYME, which is a team effort of the University of Vigo (Spain) and the FEUGA autonomous government foundation (Galicia, North West of Spain), both supported by several industrial enterprises from the Information and Communication Technologies (ICT) market. The main purpose of PROPYME project was to accomplish an innovative technology-transfer...
Typing Japanese texts with computers is not as straightforward as western ones. East-Asian languages use very large sets of symbols which are called ideograms or hieroglyphs. Typing words which are consisted of thousands of symbols is a process which must pass some procedures into which Latin characters are converted into hieroglyphs. This application is designed to assist typing Japanese texts with...
Challenges resulting from global software development are moving both industry and universities to find new strategies through which to teach and train software engineers. One of the principal challenges is that of communication which is impeded both by the geographical distribution of the stakeholders and their cultural differences. In this work we propose a tool which, by means of the simulation...
The functional decomposition is recognized as very efficient synthesis method of digital circuits and systems. However its practical usefulness for very complex systems is limited by lack of an efficient method of input variable partitioning. In this paper, a heuristic method for input variable partitioning is proposed for decomposition of Boolean function represented by BDD. The method is based on...
In the paper an application of differential evolution algorithm to training of artificial neural networks is presented. The adaptive selection of control parameters has been introduced in the algorithm; due to this property only one parameter is set at the start of proposed algorithm. The artificial neural networks to classification of parity-p problem have been trained using proposed algorithm. Results...
The paper presents a method for designing approximately linear-phase 2-D IIR filters using LS error criterion. The filter design problem is transformed into an equivalent optimization problem. The stability constraints are explicitly included into this problem. A hybrid approach for solving the considered optimization problem is proposed. In the first step, a genetic algorithm is applied. The final...
For most image fusion algorithms split relationship among pixels and treat them more or less independently, this paper proposes a region based multi-focus image fusion scheme using quality assessment of spatial domain and genetic algorithm, which combines aspects of feature and pixel-level fusion. The basic idea is to divide the source images into blocks, and then select the corresponding blocks with...
A new approach to automatic shape recognition is presented. This approach is based on backpropagation neural network. Investigations of the shape recognition were carried out for film sequences. Results of shape recognition are included in this paper.
The paper illustrates three main reasons of obtaining ineffective solutions in two-person games: unfavourable structure of the payoff matrix and ineffective strategies of the first and the last mover. It was discussed how an intervention of a third side can help in obtaining effective results.
Recently quite much attention was given to the investigation of Particle Swarm Optimization algorithm (PSO). It was proved that PSO algorithm has exhibited good performance across wide range application problems. This paper proposes the use of PSO algorithm for decision making model updating. The decision making model is used to generate one-step forward investment decisions for stock markets. The...
This paper presents the deployment of interpersonal trust for selection of partners in the community. The term trust and its representation are addressed. The risk of co-operation and its influence for selecting partners using mutual trust are studied. Our approach to the evaluation of the caution against cooperation is based on application of the game theory. Results of experiments using proposed...
