Covid-19 pandemic has made it necessary to move work from employers’ workplaces to home offices. The employee works from home using digital technologies. However, the Home Office scheme is accompanied by significant employee costs, covered by private employees’ funds. Among them for example cost of electricity, water, sewers, the cost of suitable workplace equipment and its amortization, costs of quite free space, cost to cover speedy internet. On the other hand, the employers receive work from the employees, b ut the cost of the working environment and resources they save significantly. The Home Office regime will remain in place after the pandemic, so it is time to consider a financial solution to the cost of home office staff – for example, in the form of tax instruments.

The article presents the results of the development of an information-measuring system for monitoring the sanitary status of tree stands. The main purpose of such a system is to minimize the impact of the operator on the results of monitoring the sanitary status of tree stands by indirectly controlling the quality characteristics of the tree sap (by establishing the dependence of these characteristics on climatic factors) with the possibility of remote monitoring and control of the process of express control. The developed monitoring system allows to conduct a contactless (remote) survey of sensors, which are recorded in close proximity to the root system of selective trees from an array of tree plantations, and further, by mathematical treatment of climatic characteristics (acidity and salinity index, air temperature) zoning temperature health status. The system also allows you to predict the dynamics of extending the areas of tree planting. This enables those responsible for tree planting to take preventative measures to prevent such droughts. The main advantage of the developed information measurement system is its complete computerization, which eliminates a number of external subjective influences by the operator or the responsible person (necessity of visual inspection of the maximum number of trees in the array, erroneous perception of visual information, etc.). This, in turn, avoids systematic methodological errors, thereby improving the accuracy, speed and reliability of the monitoring and control results of this system.

The paper deals with the conception of Balanced Scorecard (BSC) as an innovation strategic management system, which appears to be a superstructure of the Quality Management Systems and provides for the assessment of the basic processes in an organization. The BSC methodology and its relationship with the ISO 9001 requirements is presented and on this basis, an innovation strategy map serving the purposes of a university development has been developed.

The possibility to brake is the most important thing in the road transport safety. The effectiveness of the vehicle braking is influenced by brake fluid state – exactly the water volume share in the fluid. The brake fluid boiling point describes water volume in the fluid. By measuring the boiling point, this paper examines how a boiling point decline is influenced by the vehicle operation.

The report examines current problem in wireless WiMAX networks, namely the possible ways and mechanisms to measure the output power and power spectral density of radio transmitter. The purpose of measurement is to determine the maximum output power of the transmitter is within the manufacturer’s declared value with a certain tolerance set by EN / ETS and does not exceed the maximum limits. Also to measure or calculate the power spectral density of radiated power in the frequency channel with a specific width. The following parameters must be measured in full and coordinated load of the transmitter. These are the key parameters needed to research for the effective design of broadband WiMAX wireless data system.

At the design of heat engines like Stirling engines are, it is possible to use not only classical crank mechanisms, but also non-conventional mechanisms. Engines with non-conventional mechanisms may have several advantages when used in practice, but the design calculation model is often more difficult. This paper deals with the design of the measuring system for the measurement and diagnostic of basic parameters of the thermal cycles in Stirling engine with nonconventional FIK mechanism, which was solved in the project VEGA: Nonconventional engine FIK – Stirling. The measuring system concept is applied to a special type of piston machines with swinging mechanism that is used in this instance of a Stirling engine type. Stirling engines are currently usually used as a drives of machines for production of the electricity. There are several types of mechanisms, which are suitable by design for use in a Stirling heat engine. FIK mechanism is a swinging system, which is characterized by circular motion of the central point of the swinging plate during the rotation of the shaft. Proposed measuring systems allows to confirm the functionality of the structural design of Stirling engine with a swinging plate and examine the thermodynamic phenomena conducted in the engine cylinders.

Torque and speed measurement has always been a great challenge for many industries such as aviation, shipbuilding and automotive industry. These forces are of substantial importance for the research of the deformation processes developing in the modern marine diesel engines. The values of these forces provide the input data for calculating the overall strength of ship power plants. Continuous monitoring of these parameters while the ship is in service ensures safe operation of all machinery, reduces the risk of unplanned repair works and improves the engine performance in view of low fuel consumption and reduction of CO2 and NOx emissions.
