background: manual load lifting is the most common and stressful activity that imposes high biomechanical pressures on the body, particularly on the back. diverse studies have shown that load lifting can cause work-related musculoskeletal disorders among workers. this study was conducted to assess manual lifting activity using niosh equation and wisha index and compare the results of the two me...

هدف از این تحقیق طبقه¬بندی لندفرم¬ها با استفاده از روش فازی بر مبنای پارامتر¬های مورفومتریک در ارتفاعات زاگرس واقع در ایران است. ابتدا بهترین مقیاس با استفاده از دو روش معادله درجه دوم و lifting برای مدل رقومی ارتفاع (dem) به منظور استخراج پارامتر¬های مورفومتریک تعیین شد. نتایج نشان داد که استفاده از روش lifting برای تعیین مقیاس در مقایسه با روش معادله درجه دوم دارای دقت بیشتری می¬باشد. از ویژگ...

We develop a novel lifting technique for nonlinear system identification based on the framework of the Koopman operator. The key idea is to identify the linear (infinitedimensional) Koopman operator in the lifted space of observables, instead of identifying the nonlinear system in the state space, a process which results in a linear method for nonlinear systems identification. The proposed lift...

purpose: low back pain is one of the most common musculoskeletal disorders, and lifting is one of its risk factors. the activities of lumbar muscles as the main muscles involved in lifting are important with regard to identification of the allowable limits and the injury mechanisms as well as the motor control aspects. this study aimed to investigate the effects of the lifting speed on the lumb...

Background Biological processes such as metabolism, signaling, and macromolecular synthesis can be modeled as large networks of biochemical reactions. Large and comprehensive networks, like Metabolic-Expression networks that explicitly accounts for the demands of macromolecular synthesis at single nucleotide resolution, are inherently multiscale because reaction rates can vary over many orders ...

Classical nondecimated wavelet transforms are attractive for many applications. When the data comes from complex or irregular designs, the use of second generation wavelets in nonparametric regression has proved superior to that of classical wavelets. However, the construction of a nondecimated second generation wavelet transform is not obvious. In this paper we propose a new ‘nondecimated’ lif...

The dyadic lifting schemes, which generalize Sweldens lifting schemes, have been proposed for custom-design of dyadic and bi-orthogonal wavelets and their duals. Starting with dyadic wavelets and exploiting the control provided in the form of free parameters, one can custom-design dyadic as well as bi-orthogonal wavelets adapted to a particular application. To validate the usefulness of the sch...

This paper describes an efficient lifting based hybrid image coding (LB-HIC) scheme. The proposed scheme is based on using the lifting transform (LT) in conjunction with the discrete cosine transform (DCT) to provide coding performance superior to the popular image coders. The proposed method uses combination of the DCT coding and the high performance of the set partitioning in hierarchical tre...
