    Pēdējo gadu laikā programmatūras izstrādē arvien lielāku popularitāti gūst modeļu balstītā pieeja (MDSD – Model Driven Software Development). MDSD tehnoloģijas pamatideja ir balstīt visu programmatūras izstrādes procesu uz katrai izstrādes fāzei atbilstošiem specializētiem modeļiem. Šie modeļi ne tikai dokumentē dažādus sistēmas aspektus, bet arī kļūst par tiešu programmatūras sastāvdaļu. Mūsdienu praksē MDSD modeļu aprakstam bieži izmanto specializētas modelēšanas valodas, sauktas par domēna (priekšmeta apgabala jeb lietojumsfēras) specifiskajām valodām (DSL – Domain Specific Language). Šīs valodas ļauj uzskatāmāk un efektīvāk aprakstīt kāda specifiska problēmas apgabala modeļus, izmantojot tieši konkrētajam apgabalam atbilstošu notāciju. Līdz ar MDSD ieviešanu praksē un lietojumu arvien jaunos problēmu apgabalos, rodas vajadzība radīt jaunas DSL. Lai jaunās DSL valodas varētu ērtāk lietot praksē, to atbalstam ir nepieciešami arī rīki – redaktori, kas atvieglo jaunradīto DSL programmu (modeļu) izstrādi. Šo valodu atbalsta rīku veidošana ir darbietilpīgs process, kas prasa daudz laika. Tādēļ pastāv aktuāla nepieciešamība atrast līdzekļus, kas paātrinātu un atvieglotu šo procesu. Viens no veidiem, kā atvieglot DSL rīku izstrādi, ir radīt universālu, uz metamodeļiem balstītu rīku izstrādes platformu, kas vienkāršo rīka definēšanu, veidojot atbilstību starp konkrētās DSL valodas metamodeli (domēna metamodeli) un konkrētā rīka metamodeli (prezentācijas metamodeli). Promocijas darba pētījumi ir veltīti tieši šai tēmai – universālu, uz metamodeļiem balstītu rīku izstrādes problemātikai, precīzāk, grafisko DSL redaktoru būves platformām.In software engineering the MDSD (Model Driven Software Development) approach has gained continuously increasing popularity in recent years. The basic idea of the MDSD technology is to drive the whole software development process by specialized models that correspond to each development phase. These models not only serve as documentation of various aspects of the system, but also become a direct constituent of the software. In practice, various specialized modeling languages are nowadays used for description of the MDSD models. These languages (called Domain Specific Languages or DSLs) allow describing models of some specific problem domain more clearly and effectively by using notation designed specifically for the given domain. Along with the introduction of MDSD in software development processes and its application to new problem domains, a constant need for creation of new DSLs arises. In order for the new DSLs to be practically usable, it is also mandatory to develop supporting tools, i.e., editors for the programs (models) of newly developed DSLs. Creation of such tools is a very time consuming process, which requires a lot of effort. Therefore, there is a need for some means of speeding up and easing the development of DSL tools. One way of making the development of DSL tools easier is using a supporting universal metamodel-based tool building platform that allows simplified tool definition by creating a correspondence between the metamodel of the DSL (domain metamodel) and the metamodel of the tool being built (presentation metamodel). The research leading to this thesis is devoted exactly to this topic: universal metamodel-based tool building platforms, or to be more precise, to graphical DSL building platforms

    The power distribution is a crucial function of the satellite electrical power system (EPS) responsible for the voltage conversion, power-related measurements, and power distribution to various satellite systems. EPS of the satellite also includes energy harvesting and energy storage; due to these functions, the electrical power system is one of the most essential systems of a satellite. It must have a redundant, rigid design that can withstand some system or component failures, the temperature, radiation, and other conditions presented by the low Earth orbit environment. The different functions of EPS are performed in various locations in the ESTCube- 2 satellite - 3U CubeSat developed by the Estonian Student Satellite Foundation. It is critical to carry out thorough tests for each electrical power system element to ensure that the power requirements of each satellite system will be met. This bachelor’s thesis aims to develop an engineering model for the power distribution electronics that are located on a single board within the ESTCube-2 nanosatellite - the EPS mainboard

    MEASUREMENT OF SUSTAINABLE DEVELOPMENT IN LATVIA

    Current paradigm of economic development is sustainable development. Sustainable development is the challenge for governments, companies and households because significant additional investments and innovations, changes in production and consumption habits are required. These changes have to be made because resources are limited and existence of our world is endangered – too much resources are used and too much waste is generated by people.  This problem is recognized by the United Nations that set 17 Goals of Sustainable Development in 2015. Review of scientific literature indicates that countries measure their sustainable development in different ways because countries have different development levels, as well as different social, economic and environmental problems. Thus the aim of this research is to identify Latvian approach measuring sustainable development and assess sustainable development in Latvia. Sustainable development in Latvia is measured by indicators defined in Sustainable Development Strategy in Latvia until 2030. The methods applied in this study are literature review and regression analysis. This study reveals Latvian progress in sustainable development and relationship among strategic indicators of sustainable development in Latvia.

    IT RISK IDENTIFICATION AND ASSESSMENT METHODOLOGY

    There are numerous methods for risk identification and risk assessment phases. Which for risk identification includes historical and systematic approach and inductive or theoretical analysis. One of the main reasons why risk identification is very helpful is that it provides justification in many cases for any large IT investment and other large undertakings. Without it organization probably wouldn’t be able to come to conclusion. Also in this phase business recognize the threats, vulnerabilities, and assets associated with its IT systems. Together with risk assessment phase risk management specialist is responsible for determining asset value, what's the value of the asset business is protecting, and risk acceptance level. Risk assessment on the other hand examines impact or consequence, as well as examines and evaluates the likelihood or probability of that adverse event happening. Risk assessment includes methods like Bayesian analysis, Bow Tie Analysis, brainstorming or structured interviews, business impact analysis, cause and consequence, cause-and-effect analysis, Delphi method, event tree analysis, fault tree analysis, hazard analysis, hazard and operational studies, and finally structured what if technique or SWIFT process. Risk assessment has two distinctive assessment types- quantitative and qualitative assessment. Quantitative assessment tries to put a monetary value on all risks. Qualitative assessment on the other hand rather look at it from a range of values like low, medium, high. The results of these phases are going to be documented in the risk assessment report and reported to senior management

    Introduction: Rhythm control in atrial fibrillation (AF) patients with arterial hypertension (AH) remains complicated, attributed to pathogenetic link between both diseases. Indirect antiarrhythmic effects of medications not primarily recognized as sinus rhythm maintaining drugs, referred to as upstream therapies, including blood pressure-lowering agents, receive pathogenetically justified increasing attention. Nevertheless, studies demonstrate diverse success
