Introduction: The transparent evaluation of projects proposals for scientific research with financial support through calls made by governmental institutions or private organizations becomes extremely important, along with increasing confidence in the res... see more

In this paper, some aspects of design optimality on the basis of spring balance weighing designs are considered. The properties of D-optimal and D-efficiency designs are studied. The necessary and sufficient conditions determining the mentioned designs an... see more

The paper briefly discusses the balanced incomplete–block design (BIBD’s) and further compares two methods of analyzing them-the classical and vector space analysis of variance (ANOVA) methods. These methods are applied differently to the data arising fro... see more

It is assumed that the design of the epidural catheter may affect the quality of analgesia. Two types of epidural catheters were compared – three and six side perforation holes at the end, and the incidence of incomplete block.Methods:The study included 3... see more

The issues concerning optimal estimation of unknown parameters in the model of chemical balance weighing designs with negative correlated errors are considered. The necessary and sufficient conditions determining the regular D-optimal design and some new ... see more

Statistics has wide uses for making the right decisions in various areas of life, because statistics give a person the knowledge and ability to evaluate data. Through this research, researchers hope to create a new learning model from the results of the d... see more

In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and ... see more

In this paper we have proved that a Frobenius group of order 301cannot operate on a symmetric block design with parameters (430,78,14).

In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and ... see more
