This study seeks to reveal the attitudes of the Lithuanian adult population on using digital books and illegally distributed books and seeks to provide possible solutions to Lithuanian publishers and other institutions combating this phenomenon. A quantitative survey of 322 respondents was conducted. The analysis of the results was based on the Technology Acceptance Model, the theory of self-efficacy and the theory of planned behaviour. The results show that the ability to use digital technologies encourages the use of digital books. The perception of digital books as having value reduces the tendency to download them from illegal distribution channels. Legislative regulation does not have a significant impact on the intention not to use digital books from illegal distribution channels. It is likely that a negative assessment of the phenomenon in the immediate environment will have a greater impact on refusing to use illegally distributed books. In order to compete with illegal distribution channels, the channels for legally distributed books need to be more convenient and provide more content.

Building Information Modeling (BIM)-Systeme repr.sentieren einen ersten Schritt in Richtung eines digitalisierten und somit transparenteren Bauprozesses. Dabei wird jedoch aktuell meist nur die Planungsphase betrachtet. Somit müssen für die Bauphase oftmals zusätzliche Gesch.ftsprozessmodelle angefertigt werden. Diese Modelle sind nur selten mit einzelnen Geschäftsfällen verknüpft, sodass es schwerfällt, Aussagen über den Zustand eines laufenden Prozesses zu treffen, Kennzahlen zu erfassen oder den Prozess zu steuern und zu optimieren. Dieser Beitrag gibt einen Einblick in eine Studie der Hochschule Esslingen mit dem Familienunternehmen LEONHARD WEISS, die die Einführung eines Workflow-Management-Systems in der Baubranche als möglichen Lösungsansatz untersucht hat.

The great spread of the phenomenon of MeToo, a global movement promoting the publicity of the facts of sexual harassment, has also received a response in Lithuania: anonymous stories in blogs have grown into a provocative discourse that has attracted a great deal of attention. The aim of the research presented in this article is to characterise the discourse of MeToo in terms of rhetorical expression that has not been discussed yet: to identify and elicit the dominant elements of rhetorical argumentation. The empirical research was conducted using the method of rhetorical analysis that allows distinguishing and defining in rhetorical categories the models characteristic to rhetoric appeals. The method of rhetorical analysis combined with directed content analysis, as well as with critical discourse analysis. Following the methodology of provocative narrative research, it was analysed the material published at the time of maximum intensity and involvement in the discourse, such as testimonies, publications, interviews, and comments of women who have been subjected to sexual harassment. The results of rhetorical discourse analysis allow us to discuss the culture of accusation in which the normalization of victim condemnation is prevalent, and logical reasoning gives way to prejudice-based emotional appeals.

Received: 6 August 2020 Accepted: 15 January 2021 Vital signs are a group of essential body parameter, which provides the overall health state of a human body. They often play a pivotal role in accessing the overall physiological state of the human body. For patients requiring intense and continuous monitoring, especially those in an Intensive Care Unit, the essentiality to assess their vital signs regularly. Monitoring the health status of ICU patients becomes quite cost-effective when the same can be monitored within the comfort zone of their own house. The technique elaborated herein revolves around the fundamental idea of implementing a vital sign monitoring system that continuously assesses a patient and regularly updates the same to a centralized server system. In an event of a medical emergency, the relevant data is conveyed to the doctor via an efficient alert system, thereby ensuring safe and timely treatment to the patients. Also, as suggested the proposed design is characterized by IoT capability that allows real-time monitoring of the subject, thereby allowing, minimizing the human involvement in its operation.

Received: 7 January 2021 Accepted: 16 March 2021 This study aims to develop an autonomous combine harvester. A manual steering combine harvester was modified autonomously using navigation systems of an RTK-DGPS, a gyroscope, and crawler speed sensors. These sensors could determine the combine position and heading required to guide the path. The control system is processed for these navigation sensors' data to make the decision of combine movement. Moreover, it commands the actuator to move the steering lever mechanism. The steering control's desired heading angle was determined from lateral error, heading error, and the traveling speed. In this study, the combined harvester's average forward traveling speed was set at 0.17 m/s, adjusted to a navigation sensor's sampling rate of 5 Hz and the steering mechanism delay. The preliminary test showed the combine could turn by pivoting one of its tracks which turned the radius was into 0.4 m. Furthermore, a guidance control system of the combine harvester was developed based on this test result. The developed guidance control system was successfully guiding the combine to follow the harvesting path. The test results showed that the root mean square of the lateral error was less than 0.1 m.

Received: 30 June 2020 Accepted: 5 February 2021 The antenna is the back bone of communication. In recent time, it needs to communicate in many ways along with different types of data such as voice, video, text etc. A long distance communication satellite needs a seamless transmission. The antenna design for satellite communication is to be array type to avoid the communication failure. This insists to work with array antenna to fulfil the seam less communication through satellite. Further the antenna design depends on the geometry of the patch, the placement of the patch for better gain and bandwidth. In this paper, authors have chosen the circular patch due to its single degree of freedom. The antenna is compact and is of 30X30mm where substrate thickness is considered as 1.6mm. The central patch is of rectangular shape with two slots. Slot is made because of better bandwidth. It is cut diagonally at the corner. As a result, the bandwidth is increased to 2.4GHz with a gain of 5.68dB. The substrate is considered to be FR4 Epoxy. The proposed design satisfies the compactness along with the satellite communication band with satisfactory gain. Simulation results compromise with the measured value. A 3X3 array of circular parasitic elements is considered. It is found that the antenna performs well at 14GHz that is meant for Ku band. The radius of the parasitic patch is considered as 4mm to satisfy the less space with good performance.

Received: 8 September 2020 Accepted: 16 January 2021 Aiming at the problems that the weak current signal circuit is susceptible to noise interference and leakage current at the input terminal affects the measurement accuracy, a weak current measurement error correction scheme based on the combination of wavelet threshold denoising and generalized regression neural network (GRNN) was proposed. The scheme was applied to the error correction of multi-channel weak current measurement system based on the ADAS1134 chip: the wavelet threshold denoising was used to preprocess the original current data measured by the system and the current measurement value was corrected after the system measurement error correction model established with GRNN was constructed. Compared with the correction method based on least square method and back propagation neural network (BPNN), this method has many advantages such as high accuracy, anti-interference ability and strong generalization ability. The experimental results showed that RMSE=0.0911 nA, MAE=0.0354 nA, and MAPE=0.0078%, without increasing the complexity of the measurement circuit, which achieved the purpose of correcting the measurement error of the weak current measurement system.

The study focuses on the influence of the type of fuel on the composition of discharges in content with NOx, that is to say two cases are treated and compared. Turbulence is modeled by the k-ε model and the chemical aspect of combustion is treated by the PDF model for each flame. The calculation results relate to the characteristics of dynamic fields, temperature, the mass fractions of different species involved in the combustion process and the NOx prediction. The effect of the swirl is also tested in this study with a CFD prediction of non premixed swirling g flame. These results are compared with measurements and confrontations is satisfactory.

Received: 18 October 2020 Accepted: 22 February 2021 Several methods have been used to predict daily solar radiation in recent years, such as artificial intelligence and hybrid models. In this paper, a Wavelet coupled Gaussian Process Regression (W-GPR) model was proposed to predict the daily solar radiation received on a horizontal surface in Ghardaia (Algeria). A statistical period of four years (2013 -2016) was used where the first three years (2013-2015) are used to train model and the last year (2016) to test the model for predicting daily total solar radiation. Different types of wave mother and different combinations of input data were evaluated based on the minimum air temperature, relative humidity and extraterrestrial solar radiation on a horizontal surface. The results demonstrated the effectiveness of the new hybrid model WGPR compared to the classical GPR model in terms of Root Mean Square Error (RMSE), relative Root Mean Square Error (rRMSE), Mean Absolute Error (MAE) and determination coefficient (R).
