The block diagram of reliability analysis usage for analysis of safety critical systems

Gabriška, D.

2017 Journal of Applied Mathematics, Statistics and Informatics

doi:10.1515/jamsi-2017-0007

AbstractReliability of the technological processes or reliability of devices used in different industries is an important part of designing safety critical systems. The failure of such systems leads to economic losses, health damage or environmental pollution. An important role in the development...

Brain activity: beta wave analysis of 2D and 3D serious games using EEG

Hosťovecký, M.; Babušiak, B.

2017 Journal of Applied Mathematics, Statistics and Informatics

doi:10.1515/jamsi-2017-0008

AbstractNeuroscience and gaming are among the most rapidly increasing research areas. Today, researchers look for a way to develop a serious game, which would improve some chosen knowledge of participants at schools or work. Therefore, it is very necessary to have some feedback whether a serious...

Evaluation of Continuous Sampling Plan (CSP-5) Parameters Using GERT Technique and MATLAB

Veerakumari, K. Pradeepa; Resmi, R.

2017 Journal of Applied Mathematics, Statistics and Informatics

doi:10.1515/jamsi-2017-0010

AbstractIn this paper, we have designed the Continuous sampling plan (CSP-5) plan using GERT analysis and the software package MATLAB 2007b. The formula for finding the performance parameters such as AOQ, E(I) and the parameters i and f are found out by GERT technique and developing program for...

An Improved Family of Estimators of Finite Population Mean Using Information on an Auxiliary Variable in Sample Surveys

Singh, H. P.; Yadav, A.

2017 Journal of Applied Mathematics, Statistics and Informatics

doi:10.1515/jamsi-2017-0011

AbstractIn this paper we have suggested a family of estimators of the population mean using auxiliary information in sample surveys. The bias and mean squared error of the proposed class of estimators have been obtained under large sample approximation. We have derived the conditions for the...

Use of power transformation for estimating the population mean in presence of non-response in successive sampling

Pal, S. K.; Singh, H. P.

2017 Journal of Applied Mathematics, Statistics and Informatics

doi:10.1515/jamsi-2017-0012

AbstractThis paper addresses the problem of estimating the population mean at the current occasion in two occasion successive sampling when non-response occurs on the current (second) occasions. Using the power transformation we have suggested classes of estimators of current population mean and...
