The paper discusses the possibility of generation of a set of reusable educational components by means of paradigms of knowledge representation and management, based on contemporary concepts and tools in educational and informational technologies. Definitions of knowledge models such as ontology and characteristics of conception;model of knowledge specification and knowledge expressions by means of language specifications and graph models have been introduced. The possibility of representation of the concepts of educational material by using ontology models and characteristic models has been reviewed. The features of application of the conceptual model of knowledge for formalization of concepts of educational content and its visualization by means of interpreting language and graph models were shown based on the example of the analysis of educational content of introduction of ?Technology of programming? course.

This paper applies ant colony optimization (ACO) algorithm for the dual-pin flying probe circuit board inspection optimal path searching problem. First, the proposed approach creates a representation for circuit inspection path, which groups and encodes the measurement endpoints into a sequence. Moreover, the ant colony algorithm with the sequence can be used to solve the complex circuit optimal problem. The experimental results show that the best solutions of ACO are performed better than other algorithms.

In this paper we present an implementation of a Long-Term Evolution (LTE) signal transmission using a visible light communications (VLC) setup. VLC is a novel technology that employs off-the-shelf LED lamps to offer high-speed wireless communication, specially at indoor environments, where reportedly the majority of wireless data traffic takes place. By using the optical wireless channel, we manage to transmit downlink LTE signals in distances of up to 3 m, while keeping an EVM lower than the limit compliant.

This paper explains the generic function of implanted devices in humans to guarantee communication between patients and medical monitoring centers for emergency cases, analyzing transmission parameters, such as transfer rate, bandwidth used, data addressing, and technology comparison. The proposed architecture consists in bidirectional conveying between a web-based platform and medical external device through an Ultra-Wide Band local network. It presents an IoT architecture with its logical layers, building an infrastructure for different scenarios for patient mobility.

This paper proposes the development of a fuzzy predictive control. Genetic algorithms (GA's) are used to automatically tune the controller. A recurrent neural network is used to identify the process, and then provides predictions about the process behavior, based on control actions applied to the system. These predictions are used by the fuzzy controller, in order to accomplish a better control of an alcoholic fermentation process from chemical industry. This problem has been chosen due to its non-linearity and large accommodation time, that make it hard to control by standard controllers. Comparison of performance is made with non-predictive approaches(PID and Fuzzy-PD), and also with another predictive approach, GPC(Generalized Predictive Control).

Quantifying the effect of moisture on the electrical properties of thin dielectric films requires the use of a model that takes into account the geometry of the test structure and the dielectric properties of the air layer above the device. Using this approach, it was found that the electrical properties of dry PI (polyimide) do not change substantially after six weeks of aging at 85 degrees C/85% RH (relative humidity). The dielectric permittivity of PI as a function of %RH increased with aging for excitation frequencies between 12 Hz and 100 kHz. This increase is correlated with observed changes in the surface chemistry of the aged PI film. Shifts in ESCA peak intensities indicate oxidation of the PI surface and deimidization with aging. Possible mechanisms for the observed changes in dielectric properties with aging include a change in the morphology of the bulk PI, resulting in a decreased surface to volume ratio, increased water absorption, a change in the interaction of absorbed water with the PI matrix, and dielectric interfacial effects.< >

Without dispute, symmetrical folding waveforms are the most common type of waveform in engineering science (e.g., cosine, sine). symmetrical number systems (SNS) have been formed to extract the maximum amount of information from symmetrically folded waveforms. The robust symmetrical number system (RSNS) is formed using N ges 2 sequences and ensures that two successive RSNS vectors differ by only one digit. This Gray-code property reduces the possibility of encoding errors and makes the RSNS useful in applications such as folding analog-to-digital converters, direction finding antenna architectures and photonic processors. This paper determines the length of combined sequences that contain no ambiguities (Mcirc) which we call the RSNS dynamic range. The position of M is also derived. We first extend our two-sequence results to develop Mcirc for a three-sequence RSNS with moduli of the form 2 r - 1, 2 r , 2 r + 1. We then extend the results to solving the N-channel RSNS redundancy locations in general
