Improvement and optimization of the Powertrain mounting system are one of the ways to improve the performance NVH cars. The study aims to find the optimal stiffness coefficients for each mount in three directions. The natural frequencies of the system remain steady and stay away from the excitation frequencies, so that the system does not a resonance. It was also, using the decoupling vibration...
Unprecedented economic achievement in China has occurred along with rising resource consumption and waste productions levels. The goal of sustainability requires the decoupling of economic growth from resource consumption (resource decoupling) and environmental degradation (impact decoupling). For this paper, the performances of resource decoupling (energy and water) and impact decoupling (wast...
The notions of decoupling zeros of positive discrete-time linear systems are introduced. The relationships between the decoupling zeros of standard and positive discrete-time linear systems are analyzed. It is shown that: 1) if the positive system has decoupling zeros then the corresponding standard system has also decoupling zeros, 2) the positive system may not have decoupling zeros when the ...
Decoupling capacitor location in DC power bus design is a critical design choice for which proven guidelines are not well established. The mutual inductance between two closely spaced vias can have a great impact on the coupling between an IC and a decoupling capacitor. This coupling is a function of the spacing between the IC and capacitor, and spacing between power and ground layers. The impa...
Achieving the decoupling of electric CO2 emissions from total electricity generation is important in ensuring the sustainable socioeconomic development of China. To realize this, China implemented market-oriented reforms to its electric power industry at the beginning of 2003. This study used the Tapio decoupling index, the Laspeyres decomposition algorithm, and decoupling-related data from 199...
A new decoupling sequence, PBAR, is described for broadband heteronuclear decoupling in vivo in humans at 1.5T. The sequence uses non-adiabatic, frequency- and amplitude-modulated inversion pulses designed to minimize decoupling sidebands at low applied gammaB(2) RF field levels and to cover only the narrow range of resonance offsets encountered in practice. The offset dependence of the decoupl...
The proposed photovoltaic Micro Inverter is based on three port flyback with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the tra...
Decoupling capacitors on packages and printed circuits boards are often essential to reduce voltage fluctuations and maintain power and signal integrity. This paper presents a measure for the evaluation of effectiveness of decoupling capacitors placed on package or board structures.
We have investigated the suitability and performance of various decoupling methods on systems in which an observed spin-1/2 nucleus I (13C or 15N) is scalar-coupled to a quadrupolar spin S (2H). Simulations and experiments have been conducted by varying the strength of the irradiating radiofrequency (RF) field, RF offset, relaxation times, and decoupling schemes applied in the vicinity of the S...
