SLAmeter - The evaluator of network traffic parameters

This paper introduces the SLAmeter network metering tool, which constitutes an alternative solution to the network traffic monitoring tools based on the IPFIX protocol. The main purpose of the SLAmeter is to offer a reliable possibility to track and fulfill the conditions specified in the Service Level Agreement subscribed between the subscriber and provider. SLAmeter was designed with the extension of the BasicMeter tool and consists of several components on different layers.

Transforming Vocational education in Slovakia

This paper aims at presentation and sharing of experience and practice from Slovakia on how the Networking Academy program is working in Slovakia as part of the Vocational education system of the country. The authors present the example of the Cisco Networking Academy model - which over the past fourteen years proved to be successful worldwide and resulted in continuous growth of participating students and teachers, who are willing to follow and acquire the newest IT computer networking skills. On February 28th 2011, the Cisco Networking Academy has enrolled its 1 millionth concurrent student for the first time and 2011 is the year of the Academy Evolution process not only in Slovakia but globally.

Networking academy - innovation in education

The aim of this paper is to present and share experience from the evolution of Cisco Networking Academy program and its implementation into educational system in Slovakia. In this paper it is presented a new NetAcad partner model which replaced the one that was successful worldwide over the past fifteen years. Among the other changes that come together with academy evolution belongs a new learning environment that is also a part of this paper. The academy evolution has brought not only a new partner model but also new institutions and tasks that they provide.

Enabling long distance education with realtime video

Education as we have known is changing. Thanks to information and communication technologies we have connected and brought teachers and students together in several ways. While the modern classroom is equipped with interactive whiteboards, teachers are using laptops and presentations, collaboration and team work of students is supported with Web 2.0 tools, still the high quality of the whole educations relies in the hand of excellent teachers. For some schools though, it might be challenging to get such teachers, especially in rural regions. In this paper we are presenting our experiences using real-time communication and collaboration tools to teach complex topics to people on another side of the World. The paper shows how modern Internet tools can provide a platform and place to study online, either using advanced videoconferencing - TelePresence, or using Cisco WebEx, or Google Hangouts. It is based on a case study of a longtime cooperation in this field between the Technical University of Kosice (TUKE), Slovakia, Europe and the Paradise Valley Unified School District (PVUSD), Phoenix, Arizona, USA. The key message of the paper is: The power of high quality real-time video is in live face-to-face communication, emotions, gestures, body language, etc. Using such a communication channel we can deliver high quality education to any place on the World with Internet connectivity.

Human face detection in still image using Multilayer perceptron solution based on Neuroph framework

Artificial neural networks (ANN) are one of the dominant learning techniques used in the field of artificial intelligence and have significant assets as their properties imitate the behavior of neurons in human brain. In this paper is presented the research focused on ANN, specifically Multilayer perceptron (MPL) with the aim of detection of human face in the still image. This system was implemented in the Java programming language and its utilizing the software framework called Neuroph, which is primary used precisely for neural networks. Evaluation part presents complex testing procedures and introduces possibilities to modify and set the individual parameters that enhance the overall detection process. Novelty of this research is in the use of ANN for several reasons, one of these being the utilizing of software framework, testing of the parameters and detailed description and evaluation on what influences the detection process. However the principal strength lies in the utilization of ANN for detection of faces rather than for a recognition. Utilization of Neuroph framework is an alternative to the systems that are focused on the detection of faces in still images and are commonly implemented in different programming languages.

Virtual laboratory environment based on dynamips platform

This article deals with the solution for the next generation virtual laboratory to provide services for the operation of the remote laboratory based on dynamips solution. The work deals with the problems associated with the requirement of a flexible, secure and easy remote access to laboratory equipment. This paper provides an overview of the solution used at the DCI FEI, Technical University of Košice.

System for EKG Monitoring

In this paper the system for the electrocardiogram (EKG) monitoring based on the of Arduino microcontroller is presented. Detailed description of the electrocardiogram itself serves as a ground for building the proposed hardware and software solution. The software implementation is in a form of both, Matlab environment, and own application. Final output enables retrieval of the actual data in real time and further and provide the rudimentary diagnosis. Utilization of such device is for self home diagnosis of arrhythmia.

Web application of the SLAmeter tool

This paper provides an overview of recent development of a web application of the SLAmeter tool. The SLAmeter is a computer network traffic measuring and monitoring tool that provides various informations from collected data via its web application. Due to several performance and extensibility related problems with the former solution of the web application, the whole architecture of this top layer had to be redesigned. The main focus was therefore aimed at the new design and implementation of a thick client architecture. The achieved solution resulted in several advantages: (i) it helped to decrease the response time of the user interface, (ii) introduced new features, and (iii) enabled consistent development of new modules.

Proposal for specialized online archive of multimedia object

This article is dedicated to the online archive of multimedia objects for educational purposes. Ultimately, it is a study tool to help students better understand and deepen the information, which assume lectures or to practice the exercises. The reason to make this archive was find educational materials for the teaching of computer network KPI FEI TUKE. The first task was to understand how to develop in Drupal CMS environment for this archive. It should be vytvotiť own user interface for using custom themes written in PHP, HTML, JS and CSS. This archive was created in partnership with a number of students who cooperated in the selection of materials and the creation of the portal. This archive has general use and is easily attachable to Ostané area výčby different subjects at various universities.

Learning module of non-periodic signal digitization using ATMega328 microcontroller

Goal of the paper is to describe basic steps of continuous signal digitization. The article deals mainly with the process of sampling and linear scalar quantization. The issues of source code operation are described in brief. Measurement of sampling frequency that influences on input signal reconstruction is designed on the basis of digitization analysis. Sampling and quantization is accomplished using ATMega328P microprocessor. The contribution is the result of learning module designed and implementated for students at universities that focuses on processing electrical signals.
