It is the pursuit of a multiple-input-multiple-output (MIMO) system to approach and even break limit channel capacity. However, it always big challenge efficiently characterize MIMO systems in complex space get better propagation performance than conventional considering only free space, which important for guiding power phase allocation antenna units. In this manuscript, an Electromagnetic-Information-Theory (EMIT) based model developed efficient characterization space. The...
We report on the search for gamma ray bursts (GRBs) in energy range 1–100 GeV coincidence with prompt emission detected by satellites using Astrophysical Radiation Ground-based Observatory at YangBaJing (ARGO-YBJ) air shower detector. Thanks to its mountain location (Yangbajing, Tibet, People's Republic of China, 4300 m above sea level), active surface (∼6700 m2 Resistive Plate Chambers), and large field view (∼2 sr, limited only atmospheric absorption), ARGO-YBJ detector is particularly...
The quasiparticle model has been extended to include finite-size effects, and applied study the properties of strange quark matter strangelets. A chemical potential- radius-dependent effective bag quantity is derived. In this version model, and/or strangelets still have chance be metastable or absolutely stable. stable radius a strangelet in present smaller than, but comparable with that corresponding nucleus same baryon number, which might relevant for analysis propagation detection....
'G4argo', a GEANT4-based simulation package for the ARGO-YBJ detector, is described in this paper. G4argo incorporates true RPC time resolution and another 0.5 ns uncertainty which introduced from offline calibration of TDC. In addition, correct geometry materials experimental hall are implemented. As result, shows very good agreement with real data.
A voltage-variable capacitor is an essential part of the matching element in radio frequency (RF) circuits, including transmitting and receiving channel mobile devices. However, nonlinear characteristic produces unwanted harmonics when driven by a large exciting signal, which causes electromagnetic radiation spurious emission (RSE) complications. This article presents efficient capacitance polynomial model method coupling with test systems to predict behavior capacitor. In addition, simple...
For the problem of relatively severe lateral vibration found in vertical electrodynamic shaker experiment, an electromechanical coupling dynamic model considering low-frequency is proposed. The reason and mechanism explained analyzed through this model. To establish model, electromagnetic force overall conditions firstly built by fitting samples with neural network method. are obtained orthogonal test finite element simulation, which five factors moving coil including current, position,...
Using the data taken from Tibet II High Density (HD) Array (1997 February-1999 September) and Tibet-III array (1999 November-2005 November), our previous northern sky survey for TeV $\gamma-$ray point sources has now been updated by a factor of 2.8 improved statistics. From $0.0^{\circ}$ to $60.0^{\circ}$ in declination (Dec) range, no new with sufficiently high significance were identified while well-known Crab Nebula Mrk421 remain be brightest within field view air shower array. Based on...
<div class="section abstract"><div class="htmlview paragraph">Electric wheel systems of in-wheel motor driven vehicles consist the controller, and tire-suspension assembly. The coupling between electromagnetic excitation elastic structure gives rise to electromechanical dynamic issues. As for structural layout electric system, driving is directly connected without torsion dampers or transmission in driveline, thus making a weak damping system. Moreover, torque can change rapidly...
In ground-based extensive air shower experiments, the direction and energy are reconstructed by measuring relative arrival time of secondary particles, they deposit. The measurement precision is crucial for determination angular resolution. For this purpose, we need to obtain a precise offset each detector, apply calibration process. associated with photomultiplier tube, cable, relevant electronic circuits, etc. view transit through long cables being heavily dependent on ambient temperature,...
Inductance coupling, caused by the mutual inductance between two circuits, is a very important factor in electromagnetic interference(EMI). While calculating interference of certain source to different locations, traditional method simulate each location separately, which takes too long time and up more computer resources. This not conducive calculation complex models, especially when it necessary calculate multiple locations space. paper proposes new method, can quickly loop any position on...
The interference of Time Division Duplexing (TDD) noise on the speakers or receivers in wireless communication smart devices is investigated by simulation-measurement, which used for magnetic field coupling experiments low frequency conditions. simulation based inductance theory and design evaluation board simplified subsequent simulation. This method can be applied to more complex device boards. source was analyzed matched with experimental results. final simulation-measurement results are...
