Network resources in terms of available bandwidth are not always sufficient to provide desired quality of service, especially for real-time traffic. Network performance parameters such as delay, jitter and packet loss are significant indicators of suitability of the path for this type of traffic. To provide QoS traffic engineering methods are used. In this paper we focus on traffic engineering in...
In the modern world of today, technology means everything. It comes in many shapes and sizes: from tablets, smartphones, laptops, cars that drive themselves and flying drones. The world around us is becoming more and more interested in new inventions. With this, there is a growing need for innovations to help firefighters, doctors, automotive and people from other areas. The paper presents an alternative...
This paper deals about sensor network and its communication and energy consumption reduction. Our implementation is focused on reaching communication reduction to spare power resources on sensor nodes. To decrease amount of communication and not decrease amount information about monitored or controlled system we used data mining technique and events based communication. Data mining technique was implemented...
This contribution is part of analysis and research in field of unmanned vehicles navigation developed at Faculty of Aeronautics, Technical University in Kosice. The content of this contribution is an issue of the INS and GNSS integration. Loosely coupled integration architecture was in this case chosen as the basic for simple explanation of the integration issue. Within this contribution the emphasis...
This paper presents a comprehensive solution for path planning and control of two popular types of autonomous wheeled vehicles. Differentially driven and car-like motion systems are the most widespread structures among wheeled mobile robots. The planning algorithm employs a rapidly exploring random tree based global planner (RTR), which generates paths made of straight motion and in place turning...
An optimal control technique is proposed to address the problem of path tracking of an autonomous ground vehicle. This technique utilizes a Fractional Order Proportional Integral Derivative (FOPID) controller to control a non-holonomic autonomous ground vehicle to track the behaviour of the predefined reference path. Two FOPID controllers are designed to control the vehicle's inputs. These inputs...
While dynamically stabilized walking has many solutions already, new approaches are still possible. Described method shows combined techniques to reach efficient walk stabilization of Nao robot in RoboCup soccer simulation.
The paper deals with a development of a Mobile Vote Application (MVA), for platform called Dalvik - virtual machine which runs on mobile operating system Android integrated in many end-devices The focus of the application is to extend the functionality of the mobile device which can be used instead of voting systems' remote parts. The main goal of the application based on client-server architecture...
This paper is focused on a problematic about three-dimensional visualizations of data. The main task of visualization is to provide information to the user much more effective than raw data. We present an overview of current research in this area. Also we present our visualization tool for visualizing of critical properties of databases in the three-dimensional system. By measuring of critical properties...
The Inverted Pendulum model is one of favorite algorithm used to calculate the length of gait. The human locomotion is approximated by simple pendulum, the influence of knee and ankle movements are not considered. The gait length is calculated from the extremes of vertical position of human Center of Mass (CoM) during gait. This approach is usually used in measurements which uses inertial sensors...
Standard classification procedures of both data mining and multivariate statistics are sensitive to the presence of outlying values. In this paper, we propose new algorithms for computing regularized versions of linear discriminant analysis for data with small sample sizes in each group. Further, we propose a highly robust version of a regularized linear discriminant analysis. The new method denoted...
This paper proposes a novel approach in image compression based on Local Binary Pattern (LBP). LBP has already been used as a simple texture descriptor, labeling the image pixels by looking at the points surrounding a central point (usually on a 3×3 neighborhood) and examining whether these neighbors' color values are greater or less than the central point and accordingly assigning a binary value...
In this study, the Vehicle Routing Problem Pickup and Delivery with Time Windows (VRPPDTW) is considered. The VRPPDTW problem is seen in many practical applications such as logistics, distribution and transportation. Firstly, a new model of the very close to real-life problem is defined. Secondly, a novel heuristic algorithm with a new objective function is proposed to solve the daily macro routing...
Nowadays, public transportation has become an essential area for the actual society, which directly affects the quality of life. There are different sort of public transportation systems. One type that receives much attention these days because of its great social interest is the transportation on-demand. Some of the most well-known on-demand transports systems are the Demand Responsive Transit, and...
How to use an old turbo-compressor (turboshaft) engine and transfer it into a laboratory system used for design and development of progressive control, diagnostic and modeling algorithms transforming it into an intelligent turbo-compressor engine? The intelligent turbo-compressor engine currently designated as iSTC-21v is a small turbojet engine with a single sided radial compressor, bound combustion...
Massachusetts's Institute of Technology was the first university to provide web based university and postgraduate courses, in 2002. These courses were available on OpenCourseWare bases, which was open to anyone. The goal for the next 10 years was to provide as many online courses as possible also easily accessible to everyone. While the focus was more on the “e” part of learning, slowly the accent...
The papers presents an implementation of the predictive state space control algorithm, called Model Predictive Control (MPC). This control algorithm is verified on the Ball and Plate laboratory model, called B&P_KYB, for the reference trajectory tracking. The control algorithm is first verified using the derived nonlinear simulation model in Matlab/Simulink. Since simulation results are acceptable,...
Cloud computing is a highly discussed topic in the world of IT. The rapid development of cloud computing and the growing interest of companies in it is evident everywhere in the world.
In this paper we explain the need for a new multi-purpose Fuzzy Cognitive Maps (FCM) library and offer its proposal. Within the paper we provide an overview of available tools and libraries along with their advantages and disadvantages. We use this information in order to build a list of necessary requirements for a new library. With these requirements in mind, we offer a proposal for a new FCM library...
Product definition in virtual environment is done in the course of engineer and built in knowledge controlled generation of entities for lifecycle integrated model of product. Two recently emerged development directions in this area are company intelligent property (IP) controlled generic product model and unified abstraction based product concept model of multidisciplinary products. These two directions...
