With development of modern information and communication technologies, education became available to anyone who wishes to learn. The impact is obvious in many fields such as lifelong learning, students' self-improvement and business training. This paper focuses on presenting massive open online courses (MOOCs) as one of the concepts of modern electronic learning that extended traditional educational systems and is recognized as one of the nowadays biggest drivers of educational innovation. MOOCs enable learning through giving access to free education in form of courses from best universities from all over the world for anyone, without time or geographical limitations. This also raises many questions about pedagogical foundations of MOOCs and their validity of use in tertiary and lifelong education. Main characteristics of these courses as offered on some of the largest MOOC platforms such as Coursera, Udacity and edX will be analyzed from pedagogical viewpoint. Also, comparison between two forms of MOOCs will be given, with regard to learning theory of connectivism.

This paper describes a system of indirect measurement of the melt temperature in the converter. The system provides continuous measurement of the melt temperature during the steelmaking process. After some time, there is increasing uncertainty of these models. The need for adaptation of the models is necessary, by reason of various technological changes in the steelmaking process. One of the tasks of the adaptation module is an adaptation of the model parameters for indirect measurement of temperature, which should take into account these changes and to contribute to increase the accuracy of the whole system of indirect measurement. Adaptation module also provides additional features such as adaptation of a simulation model of the steelmaking process, data collection into the buffer of melts and selection of optimal model for indirect measurement of the melt temperature for the following melt.
本文介绍了一种间接测量转炉熔体温度的系统。该系统在炼钢过程中提供熔体温度的连续测量。一段时间后,这些模型的不确定性增加。由于炼钢过程中的各种技术变化,有必要对模型进行调整。适应模块的任务之一是适应温度间接测量的模式参数,它应考虑到这些变化,并有助于提高整个间接测量系统的准确性。适配模块还提供了额外的功能,如适应炼钢过程的模拟模型,将数据收集到熔体缓冲区中,并为后续熔体的熔体温度的间接测量选择最佳模型。

The term KDD (knowledge discovery in databases) appeared in early 90s of the last century, due to the spread of information technology in the society and as a result of information technology development. The organization of large-scale, automated collection of data in databases, in data warehouses and data repositories enables non-trivial acquisition of implicit and potentially useful information from data. This issue is in practice mostly linked to the needs of strategic management decisions. In the present paper one of the possible approaches to knowledge discovery in long-term measurement of data of a processional character is pointed out. Authors of the paper, using a special method, evaluated the long-term measurements of the air temperature in two cities (Košice, Prague). The temperature data were scanned online and transmitted to the database via the internet. The resulting two sequences of temperatures are appropriately reorganized into the structure of a vector space with the inner product. By a suitable transformation of data vectors from the time domain to the frequency domain and by subsequent visualization it was shown that the environment of man, in terms of thermodynamics, is a non-linear dynamic system with the characteristics of chaos. Although the knowledge gained only confirmed in an exact way a priori expectations, the method described can be used universally across the class of processes with the observed dynamics.
KDD (knowledge discovery in databases)一词出现于上世纪90年代初,是信息技术在社会中的普及和信息技术发展的结果。在数据库、数据仓库和数据存储库中组织大规模、自动化的数据收集,可以从数据中获取隐含的和潜在有用的信息。这个问题在实践中主要与战略管理决策的需要有关。本文指出了一种在职业特征数据的长期测量中进行知识发现的可能途径。这篇论文的作者使用一种特殊的方法评估了两个城市(Košice,布拉格)的长期气温测量结果。温度数据被在线扫描,并通过互联网传输到数据库。由此产生的两个温度序列被适当地重组为具有内积的向量空间结构。通过适当地将数据向量从时域转换到频域,并在随后的可视化中表明,从热力学的角度来看,人的环境是一个具有混沌特征的非线性动态系统。虽然所获得的知识只是以一种精确的方式证实了先验的期望,但所描述的方法可以普遍地用于具有观察到的动力学的过程类。

Multicore architectures enable increasing the performance of the system with parallel processing. One of the challenges of a multicore embedded system is the correct usage of the processor cores. It is possible to achieve balanced processor load on the different cores, but the communication bandwidth between the cores is often a bottleneck. Passing large amounts of data between tasks mapped to different processor cores can result in cache misses in the local cache of a processor core. This paper introduces an analyzation method based on runtime generated data flow graphs to find the data paths of an algorithm. It shows that a spectral cluster analysis can help to discover data independent subsets in the algorithm under test. Finding the data independent parts helps to partition the program to multiple slices where the inter-slice communication is kept as low as possible. With our proposed method the communication bottleneck can be evaded in a multicore, multitask implementation, possibly resulting in better performance.
多核架构可以通过并行处理来提高系统的性能。多核嵌入式系统的挑战之一是处理器核心的正确使用。在不同的核心上实现均衡的处理器负载是可能的,但是核心之间的通信带宽通常是一个瓶颈。在映射到不同处理器核心的任务之间传递大量数据可能导致处理器核心的本地缓存丢失。本文介绍了一种基于运行时生成的数据流图的分析方法来查找算法的数据路径。结果表明,谱聚类分析有助于发现算法中与数据无关的子集。找到与数据无关的部分有助于将程序划分为多个片,从而使片间通信尽可能低。该方法可以避免多核、多任务实现中的通信瓶颈,从而获得更好的性能。

This paper focuses on the analysis of passive optical network (Passive Optical Network - PON) by the program package OptSim and the subsequent measurement of a simulated network using OTDR (Optical Time Domain Reflectometer) in a functional physical model of optical fibre networks created by KEMT FEI TUKE (Department of Electronics and Multimedia Communications, Faculty of Electrical Engineering and Informatics, Technical University of Kosice). Nowadays, the construction of optical fibre communication systems can not function without software tools simulating a real network. This is done to avoid possible errors before the construction of communication systems. It is necessary to carry out the simulation of undesirable effects and phenomenas so that the proposed communication system is more suitable for the clients' requirements. Within the TUKE campus there is available an experimental model of the optical network represented by the various buildings connected with single-mode optical fibres type G-652_D terminated with SC / APC connectors for network types PON and FTTx. Theoretical properties of optical fibre networks type G-652_D are compared with simulated values in the program OptSim and the results are measured by OTDR.
本文重点介绍了利用OptSim程序包对无源光网络(passive optical network - PON)进行分析,并利用KEMT FEI TUKE(科斯工业大学电气工程与信息学院电子与多媒体通信系)创建的光纤网络功能物理模型中的OTDR(光时域反射计)对模拟网络进行测量。目前,光纤通信系统的建设离不开模拟真实网络的软件工具。这样做是为了避免在构建通信系统之前可能出现的错误。有必要对不良影响和现象进行模拟,以使所提出的通信系统更适合客户的要求。在杜克大学校园内,有一个光网络的实验模型,它由各种建筑物代表,用单模光纤G-652_D连接,终端是SC / APC连接器,用于网络类型PON和FTTx。对G-652_D型光纤网络的理论性能与OptSim程序中的模拟值进行了比较,并用OTDR对结果进行了测量。

The article describes proven methods for MS SQL Server Express which automatically keep the latest data in the primary database, while older data are transferred into dynamically created databases. The system was deployed in Třinecké Železárny a. s. where the data older than 30 days is kept in the primary database, and older data is transferred into databases that were dynamically created for each month of production. Thanks to this method, all databases are smaller than 2 gigabytes, while all data is easily accessible from one SQL Server Express.

The paper proposes an approach to decentralized model reference adaptive control (MRAC) design for nonlinear systems. The proposed method is based on State Dependent Riccati Equation (SDRE) approach which is an emerging design technique for the control of nonlinear systems. A nonlinear reference model is used for the adaptive control design. The plant dynamics is assumed to be nonlinear and an adaptation methodology is designed such that response of the nonlinear reference model is followed. The adaptation is performed on a state dependent basis mainly using the adaptation mechanism designed for multi input multi output (MIMO) linear time invariant (LTI) systems. Hence, a state dependent adaptation is included to the existing adaptation mechanism of the MIMO LTI systems giving a similar design approach for the MRAC of nonlinear systems. The proposed methodology is exemplified by using the simulation model of a nonlinear system, showing the effectiveness of the SDRE based MRAC for MIMO nonlinear systems.
提出了一种非线性系统的分散模型参考自适应控制(MRAC)设计方法。该方法基于状态相关里卡蒂方程(SDRE)方法,这是一种新兴的非线性系统控制设计技术。采用非线性参考模型进行自适应控制设计。假设对象动力学是非线性的,设计了一种适应方法,使非线性参考模型的响应遵循。该方法主要采用针对多输入多输出(MIMO)线性时不变(LTI)系统设计的自适应机制,在状态依赖的基础上进行自适应。因此,在现有的MIMO LTI系统的自适应机制中加入状态相关的自适应,为非线性系统的MRAC提供了类似的设计方法。通过一个非线性系统的仿真模型,验证了基于SDRE的MRAC在MIMO非线性系统中的有效性。

This paper deals with fibreless optical link in combining with Radio Frequency (RF) link. Each of links has advantages which make them convenient for reliable high speed communication link The transmission medium is air for both links. Atmospheric phenomena cause decreasing of transmitted signal in different ways. The fog, dust and small particles are critical parameter for Free Space Optics (FSO) link because they decrease visibility and availability of FSO systems. The dense rain causes attenuation of radio waves. Therefore, it is important to know when and how to do the switching process to maintain high speed data transmission process. There exist several ways, which are described in this paper and one method is used to do switching process in hybrid FSO/RF link at the Technical University's campus of Košice (TUKE).
本文讨论了光纤链路与射频链路的结合。每条链路都有各自的优点,便于建立可靠的高速通信链路。两条链路的传输介质均为空气。大气现象以不同的方式引起发射信号的衰减。雾、尘埃和小颗粒是自由空间光学(FSO)链路的关键参数,因为它们会降低FSO系统的可视性和可用性。密集的雨使无线电波衰减。因此,重要的是要知道何时以及如何做交换过程,以保持高速的数据传输过程。本文介绍了几种方法,其中一种方法用于技术大学Košice (TUKE)校区的FSO/RF混合链路的切换过程。

Caustic and sintered magnesia are the main products of magnesite thermal treatment. Caustic magnesia is generated by decomposition of MgCO3 to MgO and CO2. Sintered magnesia is generated at high temperatures at which a liquid phase is produced. Caustic magnesia is broadly used product. Because of high basicity, MgO is very convenient for reduction of water and environment acidity. The production of caustic magnesia is currently performed in rotary and multistage furnaces. The production in rotary furnaces comes with a high quantity of flue-dust - up to 35 %. The flue-dust consists of calcinated and partially calcinated particles and of magnesite dust particles with a high proportion of MgO. The flue-dust generated by current technology is captured in dust chambers, cyclones and fiber filters. The captured material is partly used for sinter magnesia production. Rest of the material is commercialized as waste with adequate low prices. In the developing technology, dust is separated from flue-gas and is directly treated in the microfluidic furnace.

烧氧化镁和烧结氧化镁是菱镁矿热处理的主要产品。烧碱氧化镁是由MgCO3分解成MgO和CO2生成的。烧结镁砂是在高温下产生的,在高温下产生液相。烧氧化镁是用途广泛的产品。由于氧化镁的碱度高,它很容易还原水和环境的酸性。烧氧化镁的生产目前是在旋转炉和多级炉中进行的。在旋转炉中生产的烟道粉尘含量很高,高达35%。烟道粉尘由煅烧颗粒和部分煅烧颗粒以及氧化镁含量较高的菱镁矿粉尘颗粒组成。现有技术产生的烟道粉尘在尘室、旋风分离器和纤维过滤器中被捕获。捕获的材料部分用于烧结镁砂生产。其余的材料作为废物以足够低的价格商业化。在开发的技术中,粉尘从烟气中分离出来,在微流控炉中直接处理。在目前的发展阶段,建立了基于元素平衡法的微流控炉数学模型。在实验炉上进行了模型充分性分析。在此基础上研制了中试微流控炉。进行了旋转炉烟气煅烧试验。

Caustic magnesia is generated by decomposition of MgCO3 to MgO and CO2. Sintered magnesia is generated at high temperatures at which a liquid phase is produced. Caustic magnesia is broadly used product. Because of high basicity, MgO is very convenient for reduction of water and environment acidity. The production of caustic magnesia is currently performed in rotary and multistage furnaces. The production in rotary furnaces comes with a high quantity of flue-dust - up to 35 %. The flue-dust consists of calcinated and partially calcinated particles and of magnesite dust particles with a high proportion of MgO. The flue-dust generated by current technology is captured in dust chambers, cyclones and fiber filters. The captured material is partly used for sinter magnesia production. Rest of the material is commercialized as waste with adequate low prices. In the developing technology, dust is separated from flue-gas and is directly treated in the microfluidic furnace.

This paper describes a laboratory model for experiments with an active vibration control. This test rig is consisting of steel cantilever beam connected to aluminium frame in vertical position; stack piezoactuator fixed near clamped end of the cantilever beam and a piezoelectric accelerometer positioned at the free end of the beam. Control algorithm is implemented into digital signal processing system. Experiments with suppression of several vibration modes were performed on this laboratory model.
