In this paper, systematic mismatch due to parameter gradients is modeled and analyzed. A new layout strategy with flexible cell placement is proposed. Theoretical analysis shows its property of canceling the mismatch between two devices due to up to n order gradient effects by using 2 unit cells for each device. Simulation results show that the proposed technique gives better matching character...

objectives lipid components of spermatozoa have an important role in its functional activity. in this study the concentration of cholesterol, phospholipid, triacylglycerol and total lipid in different subsets of human spermatozoa, isolated as three fractions by a discontinuous puresperm gradient, was determined. methods aliquots of the liquefied semen samples (n=107) were layered on top of the ...

in a large scale cyclic storage system ,as the number of rule parameters and/or number of operating period increase, general purpose gradient-based nlp solvers and/or genetic algorithms may loose their merits in finding optimally feasible solution to the problem. in these cases hybrid ga which decomposes the main problem into two manageable sub-problems with an iterative scheme between ga and l...

Electromagnetic tomography technology is a new process tomography technology. The aim of this study is to develop a new image reconstruction algorithm suitable to electromagnetic tomography and verify its convergence. The advantages and development of electromagnetic tomography technology and image reconstruction algorithms are introduced briefly. Based on conjugate gradient algorithm, modified...

The process to produce an MR image includes nuclear alignment, RF excitation, spatial encoding, and image formation. In simple terms, an magnetic resonance imaging (MRI) system consists of five major components: a magnet, gradient systems, an RF coil system, a receiver, and a computer system. To form an image, it is necessary to perform spatial localization of the MR signals, which is achieved ...
