Stability analysis of geomagnetic baseline data obtained at Cheongyang observatory in Korea

On the feasibility of routine baseline improvement in processing of geomagnetic observatory data

We propose a new approach to the calculation of regular baselines at magnetic observatories. The proposed approach is based on the simultaneous analysis of the irregular absolute observations and the continuous timeseries deltaF, widely used for estimating the data quality. The systematic deltaF analysis allows to take into account all available information about the operation of observatory in...

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Using of frailty model baseline proportional hazard rate in Real Data Analysis

Many populations encountered in survival analysis are often not homogeneous. Individuals are flexible in their susceptibility to causes of death, response to treatment and influence of various risk factors. Ignoring this heterogeneity can result in misleading conclusions. To deal with these problems, the proportional hazard frailty model was introduced. In this paper, the frailty model is ex...

Proceedings of the XIV IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition, and Processing - Preface

The XIVth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition, and Processing was the first of its kind to take place in China, the country regarded as the birthplace of geomagnetism. These workshops are scheduled to take place every 2 years, and as such, it is an important meeting for all magnetic observatories to attend. These workshops serve to provide the standard of obse...
