Simulation of Livestock Breeding Economics in Conditions of the EU

In the paper there are described mathematical principles of biological, technological and economic model relations and connections in animal breeding on which the mathematical model AGRO-ZV is based. With the model it is possible to simulate impacts of the agricultural policy on livestock breeding economics and commodity economics in dependence on different agricultural policy variants. In the article there is illustrated a usage of the model for simulation of dairy cattle economics before (2003) and after (2004) the accession of the Czech Republic to the EU.mathematical modeling, livestock breeding, dairy cattle econmics, model AGRO-ZV, Livestock Production/Industries,

The Architecture of the Blind User Oriented Hypertext AUDIS

. The architecture of the blind user oriented hypertext AUDIS developed at the Faculty of Informatics, Masaryk University Brno, is described in the paper. AUDIS is developed primarily as a support, which would help visually impaired students to study various materials. It can also serve as an Internet browser. 1 INTRODUCTION Speech synthesizer and "screen access" ("screen reader") software represent basic utilities used by blind users to obtain hypertext information. Although present conventional hypertext and fulltext systems are very sophisticated and user-friendly, they are not very convenient when they are to be used by visually impaired people. The reason is the graphical interface and absence of the features fulfilling special needs of the blind people ([1]). In what follows we will describe the basic features of the hypertext system AUDIS developed for blind users. The hypertext system AUDIS is primarily developed to provide comfortable accessibility to textbooks for visually i..

Navigation and Information System for Visually Impaired People

. Orientation is one of the most important problems of visually impaired people. The aim of this paper is to suggest a contribution to the solution of this problem using computer technology. The basic idea is the detection of motion and orientation using sensors and consequent position identification. The detected trajectory is compared with a map and is corrected by means of the algorithm described in the paper. Some problems concerning sensor detection of human motion are also discussed. Based on the determined position other relevant information is provided to the user of system (information describing the neighbourhood of the actual position, optimal way to the chosen destination, possible warnings). 1 Introduction Contemporary information technology o#ers various possibilities for solving many problems of handicapped people. Serious impairment of sight is a considerable limitation for such people. The main problem is a substantial information deficit and its feedback --- communic..

Leolani: A reference machine with a theory of mind for social communication

Our state of mind is based on experiences and what other people tell us. This may result in conflicting information, uncertainty, and alternative facts. We present a robot that models relativity of knowledge and perception within social interaction following principles of the theory of mind. We utilized vision and speech capabilities on a Pepper robot to build an interaction model that stores the interpretations of perceptions and conversations in combination with provenance on its sources. The robot learns directly from what people tell it, possibly in relation to its perception. We demonstrate how the robot’s communication is driven by hunger to acquire more knowledge from and on people and objects, to resolve uncertainties and conflicts, and to share awareness of the perceived environment. Likewise, the robot can make reference to the world and its knowledge about the world and the encounters with people that yielded this knowledge
