    Higher education as the education whole faced an unprecedented challenge last year. Due to the Covid-19 pandemic, the educational process had to change rapidly. The need for redesign and renovation was obvious already before the crisis driven by the pandemic started. As all other methods have become more personalised, education had to follow. In the current paper, the authors will solve the efficient delivery of know-how and skills requested by developing Component Organised Learning components that can be applied in different courses. The required solution should find a way to use the COL concept to avoid the repetition of materials and excessive work of collaborative HEI-is.

    Application of Fuzzy Rule Base Design Method
    (2016)
    Grabusts, Pēteris 
    In many classification tasks the final goal is usually to determine classes of objects. The final goal of fuzzy clustering is also the distribution of elements with highest membership functions into classes. The key issue is the possibility of extracting fuzzy rules that describe clustering results. The paper develops a method of fuzzy rule base designing for the numerical data, which enables extracting fuzzy rules in the form IFTHEN. To obtain the membership functions, the fuzzy c-means clustering algorithm is employed. The described methodology of fuzzy rule base designing allows one to classify the data. The practical part contains implementation examples.

    Automotive mechatronics involves the multidisciplinary integration of automotive mechanical and electronic systems. As such, automotive mechatronics education integrates knowledge and competences across automotive-specific mechanics, electronics, communication, advanced control, and modeling. Over the last few years, the subject of autonomous vehicles has been attracting significant attention from researchers, as well as interest from the media and the public at large. It encompasses a myriad of new applications, ranging from driverless cars to airborne surveillance of sensitive areas. Designing solutions for autonomous vehicles requires the integration of hardware and software components, as well as interaction with cloud-based servers. This paper focuses on autonomous/unmanned ground vehicles within the scope of a mechatronics curriculum. It has been proposes an educational model for autonomous vehicles for inclusion in the new mechatronics curriculum of NewMetro, an EU funded project that aims to develop an innovative European framework of competences for mechatronics education.

    Digital technology allows an individual to simultaneously interact with a multitude of people and with smart objects, namely intelligent devices and electronic programs. As a consequence, new modalities for involving citizens in participatory processes can be applied.Applications can be created with the goal of collecting data as well as ideas, suggestions, and opinions from the multitude of citizens at large, but citizens need to be motivated to participate and be able to trust that their privacy will be respected. In this article, we propose a mobile platform, called Citybook, that aims to provide citizens with a personal smart diary that includes itineraries, automatic generated searches, repositories for images and videos, and functions for sharing personal feelings, opinions, and suggestions with other users and with public services.We present the functional structure of this platform, which has been conceived in a perspective of smart and connected communities. It should also be able to integrate crowd sensing with existing data repositories via an OpenData approach.

    Latviešu valodas apguvēju korpuss lietojumā: teorētisks un metodoloģisks ieskats
    (2021)
    Kļavinska, Antra 
    Several text corpora have been created in Latvia, including learner corpora. One of the latest projects is the Latvian Language Learner Corpus (LaVA), which contains the works of international students studying in Latvian higher education institutions who are learning Latvian as a foreign language. The texts are morphologically tagged automatically, and learner errors are tagged manually. A sufficient scope of publications is available, which provides the theoretical basis for the creation of Latvian language learner corpora; however, there is a lack of studies or practical methodological guidelines concerning the opportunities for their application, and there is little data about the use of text corpora in language acquisition. The aim of this study is to explain from the theoretical perspective for what purposes learner corpus data may be used, as well as to illustrate the methodological groundwork with examples from the LaVA corpus. Analysis of theoretical literature has demonstrated the functions and meaning of learner corpora in research, and experience with the use of corpora in acquiring a foreign language has been analysed. Examples of the use of the LaVA corpus as a didactic resource have been prepared using Corpus Linguistics methods. The study was conducted within the state research programme project “The Latvian Language”. After studying the functions of learner corpora from the theoretical perspective, it was concluded that the target audience of the LaVA corpus mainly includes teachers of Latvian as a foreign language (LATS), authors of teaching materials, as well as Latvian language learners. To facilitate the use of the LaVA corpus, it is important to have basic knowledge of Corpus Linguistics, an understanding of the theory of language, as well as an understanding of foreign language teaching methodology. LATS teachers can use the LaVA corpus data in the creation of curricula and teaching materials, in the preparation of language proficiency tests, etc. Using the inductive approach in language acquisition, language learners can also become language researchers, can analyse the errors of other learners, etc. Undeniably, the LaVA corpus can be used in broader linguistic research, for example, in contrastive interlanguage analysis, comparing the data of language learners with the data of native speakers or the data of different groups of language learners.

    Silver has been an influential segment of pharmaceutical utilization for remedies & hygiene in the latest era. The first topic reviews the study on air sanitization ventilation & air sanitizer systems using laser ablated silver nanoparticles (inspired by 2020 Pandemic) directing to contamination of deadly biological particles. Intention of this investigation is to validate possible antiviral silver nanoparticles construction to be distributed by retention, to abate the aggravation of breathing organs flu. The underlying description of investigation consists of bibliometric reasoning of the review of the outcome of silver nanoparticles on the sterilization of viral ailments. The investigation will deliberate the approach of use of laser ablated silver nanoparticles for anti-actions. The chapter outcomes in the fascinating utilization of silver nanoparticles for pharmaceutical purposes for contagious diseases, viruses or bacteria and devotes to the upgradation of therapeutic education to safeguard health care workers from threatening viruses at therapeutic organizations. Morally, the investigation will obtain a hygienic scheme, which might be installed at every communal or individual places cost-effectively including silver nanoparticles (because of their therapeutic properties). The second section of investigation considers distinct techniques for manufacturing silver nanoparticles. The various schemes have been compared based on their pros & cons. The method of laser ablation for generating nanoparticles underwater is briefed. The intention of this part is to disclose the current & anticipation probabilities of the process - laser ablation, as a profitable and eco-favorable innovation for manufacturing silver nanoparticle in liquid solutions. The chapter is motivated by two of our reviewed papers i.e., “Antibacterial and anti-viral effects of silver nanoparticles in medicine against covid 19” and “Methods for obtaining silver nanoparticles”.
