In order to discover interesting patterns and dependencies in data, an approach based on rough set theory can be used. In particular, Dominance-based Rough Set Approach (DRSA) has been introduced to deal with the problem of multicriteria classification. However, in real-life problems, in the presence of noise, the notions of rough approximations were found to be excessively restrictive, which l...

We investigate the large sample behavior of a p-value based procedure for estimating the threshold level at which a regression function takes off from its baseline value – a problem that frequently arises in environmental statistics, engineering and other related fields. The estimate is constructed via fitting a “stump” function to approximate p-values obtained from tests for deviation of the r...

Automatic threshold selection in regression method of change detection in remote sensing images is investigated in this paper. We have reviewed the three well-known automatic threshold selection methods in the image processing field; namely, convex hull, Otsu, and ISODATA. We have then described the adaptive threshold selection concept. We have then shown that from these three methods, only the...

We use p–values as a discrepancy criterion for identifying the threshold value at which a regression function takes off from its baseline value – a problem that is motivated by applications in dose-response studies, astronomy and engineering. In this paper, we study the problem in a controlled sampling setting, where multiple responses, discrete or continuous, can be obtained at a number of dif...

Abstract—Analysis of the uncertainty quantification related to nuclear safety margins applied to the nuclear reactor is an important concept to prevent future radioactive accidents. The nuclear fuel performance code may involve the tolerance level determined by traditional deterministic models producing acceptable results at burn cycles under 62 GWd/MTU. The behavior of nuclear fuel can simulat...

There are various causes for inflation in macroeconomics. One of the important channels of experiencing inflation is through the international economy caused by external shocks. In this context, the impact of exchange rate volatilities on domestic prices known as Exchange Rate Pass-Through (ERPT) plays a vital role. The present paper deals with the impact of Exchange Rate Pass-Through on inflat...

Within organisations, business processes are increasingly supported by socio-technical systems — combinations of people and technologies working synergistically. In the commercial sector at least, business processes are increasingly complex and volatile due to the rapid pace of change in the marketplace, and this has an impact on their supporting systems. In this sector, organisations feel the ...
