هدف از انجام این پژوهش ارائه الگوی برنامه کلان ملی شفافیت و آزادسازی اطلاعات می‌باشد. دارای رویکردی تلفیقی (کیفی کمی) بوده روش نظریه داده‌بنیاد (گراندد تئوری) به‌عنوان تحقیق استفاده شده است. در بخش کیفی با بررسی عمیق اکتشافی قوانین اسناد بالادستی، الگوها، نظریه‌ها، برنامه‌ها کشورهای مختلف مرتبط اطلاعات، تحلیل داده‌ها تا حد اشباع نظری، طی سه مرحله کدگذاری باز، محوری انتخابی گرفت. به‌منظور دستیاب...

Recent literature has investigated the risk aggregation of a portfolio X = (Xi)1≤i≤n under the sole assumption that the marginal distributions of the risks Xi are specified but not their dependence structure. There exists a range of possible values for any risk measure of S = ∑n i=1Xi and the dependence uncertainty spread, as measured by the difference between the upper bound and the lower boun...

Abstract In time series analysis auto regressive (AR) modelling of zero mean data is widely used for system identification, signal decorrelation, detection outliers and forecasting. An AR process order p uniquely defined by r coefficients the variance noise. The roots characteristic polynomial can be as an alternative parametrization coefficients, which to construct a continuous covariance func...

It is well known that the time-varying parametric model based on wavelet neural network has excellent performance on modeling a signal. The spark discharge signal is a typical nonstationary one. The spark discharge has two types in a static dust catcher. one is normal discharge, another is antielectric-corona discharge. A few simulations indicate that the performance of the TVAR model on modeli...

We thank the discussants for their kind comments and questions, and the interesting questions raised. We address the contributions by named discussants. DANIEL PE ~ NA Professor Pe~ na contributes some insightful discussion and provides useful additional references and connections to recent literature. We are particularly interested in following up his commentary on factor models and look forwa...

Hypertension is a global challenge to the public health which can easily lead life-threatening vascular diseases unless control measures are adopted. Considering prevalence of and their fatality, early detection high-risk patients an important problem in present world. Heart rate variability (HRV) analysis be effective prognostic tool identify characteristics vulnerable patients, considering it...
