Estimating the frequencies of multiple superimposed exponentials in noise is an important problem due to its various applications engineering. In order obtain good inhibition spectral leakage and improve estimation accuracy, improved Chirp-Z transform (CZT) algorithm proposed for high-precision frequency estimation. Firstly, analyzes characteristics CZT spectrum utilizes construct a bias correc...

We consider the estimation of sparse graphical models that characterize the dependency structure of high-dimensional tensor-valued data. To facilitate the estimation of the precision matrix corresponding to each way of the tensor, we assume the data follow a tensor normal distribution whose covariance has a Kronecker product structure. The penalized maximum likelihood estimation of this model i...

  This paper aimed at estimation of the per capita consumption of electricity in residential sector based on economic indicators in Iran. The Genetic Algorithm Electricity Demand Model (GAEDM) was developed based on the past data using the genetic algorithm approach (GAA). The economic indicators used during the model development include: gross domestic product (GDP) in terms of per capita and ...

Accurately estimating human pose is crucial for providing feedback during exercises or musical performances, but the complex and flexible nature of joints makes it challenging. Additionally, traditional methods often neglect pixel coordinates, which are naturally present in high-resolution images body. To address this issue, we propose a novel estimation method that directly incorporates coordi...

Partners HealthCare Personalized Medicine (PPM) is a center within the Partners HealthCare system (founded by Massachusetts General Hospital and Brigham and Women's Hospital) whose mission is to utilize genetics and genomics to improve the care of patients in a cost effective manner. PPM consists of five interconnected components: (1) Laboratory for Molecular Medicine (LMM), a CLIA laboratory p...
