consistency

The authors developed a system of criteria for assessing data quality in the context of distributed information systems. The article describes a set of data quality dimensions formulated based on the challenges of data storage and processing in distributed environments. The main objective of the research is to identify the primary requirements and challenges faced by distributed information resources and to satisfy them with specifically selected data quality criteria.

The emergence of microservice architecture has revolutionized software development practices by decentralizing components, facilitating scalability, and enabling agility in system design and deployment. There are some benefits of incorporating microservices instead of a single server, however, distributed components introduce extra constraints and complexities in maintaining data consistency as well. As microservices interact independently, coordinating data updates across multiple services becomes challenging, particularly in scenarios where transactional integrity is required.

Dry mix mortars are widely used in construction projects for the implementation of construction works in new construction, reconstruction, and repair. The improvement of properties of dry mix mortars for the installation of floor screeds is relevant. The purpose of such mortars is to equalize the differences in the thickness of the floor surface, to create an intermediate layer characterized by the necessary strength, durability, and even surface with the possibility of decoration with various types of flooring.

Discrete estimators of the deterministic part for a biperiodically nonstationary signal obtained by the least square method (LSM) are analysed.  It was shown that LSM-estimation allows avoiding the leakage effects.  The conditions of consistency for the discrete estimators are obtained.  The formulae for variance estimators, which describe their dependencies on a realization length, sampling interval and signal covariance components, are analysed.

The article deals with the algorithmic method for precision enhancement of paper pulp blade consistometers . In the said method, the current strength in the winding of a moving coil of a magnetoelectric transducer in the steady regime of sensor`s blade motion condition is measured during its movement in downstream and upstream directions. Thus, we can minimize the error resulting from the impact of changes in flow velocity relative to paper pulp measuring blade of the consistometer. Schematic diagram of a paper pulp consistometer with paper pulp flow velocity compensation is presented.
