Numerical methods for strongly oscillatory and singular functions are given in this paper. We present an alternative numerical solution for of oscillatory integrals of the general form Where and are smooth functions in the interval [a, b]. Also ε ω and . In order to achieve this goal and avoid singularity, the mentioned integral is solved by the modified moments using interpolating at the Cheby...

Abslrnrf This paper aim to consider using the Wavelel Transform ( WT), WignerVille Distribution ( W O ) and ChoiWilliams Distribution (CWD) applied for spectrum estimution of non-stationary signals in power sysfems. The main goal is lo emphasize advantage and disadvantage of mentioned methods in comparison with Shun-Tinu Fourier Transform (STFT). Especial& the aspect offrequency resolution are ...

The goal of this essay is to give an overview of distance learning. This is a very broad and interesting field, and it could be studied from many different perspectives. Here we focus on the history, different types of distance education, corresponding design challenges and technological solutions and present some examples of commercially available software systems. We devote less attention to ...

The goal of the study was to explore low-income minority patients' concepts of diabetes self-management and assess the extent to which patient beliefs correspond to evidence-based recommendations. African American and Mexican American patients with type 2 diabetes were recruited from safety net clinics that serve the uninsured and under-insured in Chicago and San Francisco to participate in foc...
