This paper considers the simple step-stress model from the Marshall-Olkin generalized exponential distribution when there is time constraint on the duration of the experiment. The maximum likelihood equations for estimating the parameters assuming a cumulative exposure model with lifetimes as the distributed Marshall Olkin generalized exponential are derived. The likelihood equations do not lea...

In this paper we investigate generalized ordered (GO) spaces that have a flexible diagonal in the sense of Arhangel’skii [2]. Spaces with a flexible diagonal are generalizations of topological groups and include spaces that are continuously homogeneous, Choban spaces, and rotoid spaces. We prove some some paracompactness and metrization theorems for such spaces and construct examples of general...

this research was performed to monitor the effects of different practice schedules on learning and transfer of generalized motor program and timing parameter in a serial task. for this purpose, 80 participants (age: 19-23 years) voluntarily participated in this research and then they were divided randomly into 4 groups: blocked, random, blocked-random and random-blocked. this test included perf...
