A major objective of FP7 LIREC project (Living with Robots and Interactive Companions) lies in designing a robotic companion that humans would accept and co-exist with over a longer period of time. A tentative construction of such a companion has been a robot mounted on board of a balancing mobile platform. In this paper we describe a prototype design of the balancing robot, derive a mathematical model of its kinematics and dynamics, and develop a robot controller. The controller synthesis is based on feedback decoupling and linearization of the robot dynamics. Performance of the controller has been tested by computer simulations of example problems of position and orientation tracking.
Making good operation decisions during abnormal power plant conditions represents in many cases the possibility to avoid a unit trip or having economical losses. This paper introduces AsistO, an intelligent assistant ...

The paper presents a hybrid model of the bots detector which is a combination of host intrusion detection system and the operating system event log analyzer. Bot can be defined as a computer that have been attacked by a hacker or infected with malicious software and is used for illegal activities. Collections of infected computers form a botnet. The proposed system is used to detect bots based on the evaluation of events occurring in the operating system and network environment. Detection algorithms based on the signatures derived from the analysis of the various types of malicious software that creates bots. The model has been implemented using multi-agent technology.

This paper presents an investigation into feasibility performance gains for routing protocols. Routing protocols are crucial for WSN activity because sensors are not capable to realise individually overall system tasks. Because of that, sensors need to have more or less tightly integrated cooperation, based on information exchange, between them. We propose relational approach, based on set theory, which considers three relations: subordination, tolerance and collision. Using these relations we perform initial organization, but there is no necessity to perform any reorganization during a network lifetime. The obtained results show that providing relatively high collision intensity quotient, nodes can avoid selectively malfunctioned nodes. On the other side, decreasing subordination intensity quotient inhibits error dissemination process.

Problem of scheduling n preemptive jobs on a single processor is studied, in which for each job a distinct due window is given in advance. If a job is completed within its due window, then it incurs no penalty. Otherwise, it incurs a job-independent earliness or tardiness cost. The objective is to find a job schedule such that a maximum of weighted costs associated with earliness and tardiness is minimized. Properties of optimal solutions of this problem are established and an algorithm based on them is presented. It is proved that the analysed problem is solvable in O(n2) time.

The following paper presents the effects of work on evaluating application of structure-from-motion 3D reconstruction algorithms to the purpose of computer-guided surgical training. In the paper a system for laparoscopic surgery training is presented. The key part of the system is a novel approach to training, where a 3D model of the operating fields serves as a base of the interaction between the trainee and the system. Outline of the 3D processing pipeline is presented, results are shown and discussed.

The aim of this paper is to show, using chosen example, the possibility to analyze a set of feasible solutions for a certain dual-criteria, complex decision making problem. The analyzed problem concerns, in particular, the designing of a detached one-family cottage. The criteria include the total cost of building the house and its durability. The area of decision variables contains 22 elements, for which each element can have one of five values corresponding to the available building technology. The effect of the analysis carried out is the determination of the set of optimal solutions in the Pareto sense for the designing task. This set contains only five elements.

A paper presents an approach to critical situations analysis related to discrete transport systems (DTS). The critical situation is understood as sudden shortage of some system recourses resulting in the transport system performance degradation. The analysis is realized based on availability calculation of DTS. The system is described by the formal model, which includes reliability and functional parameters of DTS. The availability and average availability of the system - defined in a functional way by delayed tasks realization, is discussed as a function of different essential parameters when the DTS is organized. The proposed analysis is based on the modeling and simulating of the system behavior using Monte Carlo approach. The paper presents some exemplar systems, based on real Polish Post DTS, modeling and results.

Classification is an important data mining task in biomedicine. For easy comprehensibility, rules are preferrable to another functions in the analysis of biomedical data. The aim of this work is to use a new fuzzy immune rule-based classification system for biomedical data. The performance of the proposed approach, in terms of classification accuracy and area under the ROC curve, was compared with traditional classifier schemes: C4.5, Naive Bayes, K*, and Meta END.
