This study aims to identify the fatigue lifetime of a thin-walled hollow spherical rubber isolator subjected harmonic and random vibrations. Firstly, nonlinear characteristics materials are tested analyzed through vibration experiments. The relationship among stiffness, damping, relative displacement amplitude is established. Secondly, an accelerated experiment under excitation carried out. cor...

OBJECTIVES To predict the incremental lifetime effects, costs, and cost effectiveness of using human papillomavirus testing to triage women with borderline or mildly dyskaryotic cervical smear results for immediate colposcopy. DESIGN Modelling study. SETTING Three centres participating in NHS pilot studies, United Kingdom. Population Women aged 25-64 with borderline or mildly dyskaryotic ce...

BACKGROUND Across sub-Saharan Africa, men's levels of HIV-testing remain inadequate relative to women's. Men are less likely to access anti-retroviral therapy and experience higher levels of morbidity and mortality once initiated on treatment. More frequent HIV-testing by men at continued risk of HIV-infection is required to facilitate earlier diagnosis. This study explored the frequency of HIV...

User studies have revealed that programmers face several obstacles when learning application programming interfaces (APIs). A considerable part of such difficulties relate to discovery of API elements and the relationships among them. To address discoverability problems, we show how to complement APIs with design annotations, which document design decisions in a program-processable form for typ...

Statistical distributions are very useful in describing and predicting real world phenomena. Consequently, the choice of the most suitable statistical distribution for modeling given data is very important. In this paper, we propose a new class of lifetime distributions called the Weibull Topp-Leone Generated (WTLG) family. The proposed family is constructed via compounding the Weibull and the ...

Comparison of the theory of Rabi oscillations with experiment [M. Wilczewski and M. Czachor, Phys. Rev. A 79, 033836 (2009)] suggests that cavity lifetime parameters obtained in measurements with many photons may be much smaller than those applicable to almost vacuum states of light. In this context, we show that the conclusion remains unchanged even if one takes a more realistic description of...
