Abstract—A coherent processing method for subband signals of distributed multi-band radar data is proposed and tested. The method uses de-noising cross-correlation (DNCC) algorithm and statistical method to obtain phase incoherent parameters (ICP) between subband signals. After compensating the phase ICP, a coherence function is defined and combined with statistical method to find amplitude ICP...

one of the main functionalities of capital market is to improve liquidityin the market which provides security for the investors. mutual funds aremodern financial institutions which are designed with the aim of collectingfunds from investors and devote them to buy a variety of securities inorder to mitigate investment risks, exploit the economies of scale andfinally create a reasonable return f...

T he main purpose of this paper is to analyze the performance of mutual funds in Iran by using Fama decomposition model (1972). Thus, daily data of 55 mutual funds during a four-year period from 21/3/2014 to 21/3/2018 were investigated. To achieve this goal, firstly, the performance of mutual funds was broken down into Fama components, and it was shown that the diversification perfor...

financial literacy of investors reduces uncertainty on future decisions and increases predictability of investment policies in financial markets. thus, the lack of clear information on financial markets is a determining factor in the arrival of domestic and foreign capitals and their quick exit in case of crisis. the lack of transparency and basic knowledge on decisions and failure to provide r...

This paper presents a novel segmentation method for the joint segmentation of individual bones in CTor CT/MRhead&neck images. It is based on an articulated atlas for CT images that learned the shape and appearance of the individual bones along with the articulation between them from annotated training instances. First, a novel dynamic adaptation strategy for the atlas is presented in order to i...

The average level and cross-sectional variability of fund alphas are estimated from a large sample of mutual funds. This information is incorporated, along with the usual regression estimate of alpha, in a (roughly) precision-weighted average measure of individual fund performance. Substantial ‘‘learning across funds’’ is documented, with significant effects on investment decisions. In a Bayesi...

The objective of the study was to test whether Gray’s ‘‘Behavioural Inhibition System’’ (BIS) is a pathway from mindfulness towards well-being in a cross-sectional and correlational design, using online data collection. We administered the Freiburg Mindfulness Inventory (FMI) and the Kentucky Inventory of Mindfulness Skills (KIMS) to a non-clinical sample of German adults (n = 211). BIS was mea...
