Constraints on Skeptical Hypotheses

In this article I examine the constraints that skeptical hypotheses must satisfy in order to be used to raise significant skeptical challenges. I argue that skeptical hypotheses do not have to be logically, metaphysically or epistemically possible. They only need to depict scenarios that are subjectively indistinguishable from the actual world and must provide some indication of how subjects ca...

On Bootstrap Tests of Hypotheses

The size of the bootstrap test of hypotheses is studied for the normal and exponential one and two-sample problems. It is found that the size depends not only on the problem, but on the choice of test statistic and the nominal level. In some special cases, the bootstrap test is UMP, but in other cases, it can be totally useless, such as being completely randomized or rejecting the null hypothes...

Testing fuzzy hypotheses with vague data

The problem of testing fuzzy hypotheses in the presence of vague data is considered. A new method based on the necessity index of strict dominance (NSD) is suggested. An example hoe to apply the proposed test in statistical quality control is shown.

On the effect of grain size on rock behavior under cyclic loading by distinct element method

It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
