This paper proposes a novel actuation system for simultaneous planar position control of two identical magnetic microrobots. Four rotating permanent magnets are used to produce the desired magnetic field and consequently desired magnetic force. Angles of the permanent magnets are found analytically by PI...
In the case of an assembly of non-interacting randomly oriented identical NPs, the hysteresis loop features a remanent magnetization Mr = 0.5 MS and a coercivity HC = 0.48 µ0HK. Accordingly, the loop area is reduced and it can be approximately estimated as A≈4μ0MrHC=2μ0MSHC=1.92...

current of 10 mA are virtually identical. Also, such deviation is not expected from conductance corrections due to electron–electron interaction or quantum interference effects. The lower temperature limit for the T1/2 regime is given theoretically by TD ¼ 1CK sDy2s/tTemK,sf1r4omandwhfricoh...
where L is the length of the packed section; vsv is the superficial velocity of the total liquid flow; dm is effective particle diameter (given by six times the mean ratio of particle volume to particle surface area); and φ is the volume fraction of voids (flow channels) within the bed...
length up to 90 μm in h-BN encapsulated bilayer graphene by using carrier drift. However, the weak SOC and zero bandgap in intrinsic graphene restrict its prospects for semiconducting spin devices. Black phosphorus has a sizeable direct bandgap and room-temperature mobility of 1000 cm2V−1s...
The device forming a homogeneous magnetic field uses two permanent magnets (1,2) spaced apart. Each magnet is shaped as a cone with its frustum cut off, and the bases of the cones face outwards away from each other. Both magnets are the same size. The included angle of the two cones ...
During the experiment, the used sampling frequency of the recording data was 256 Hz and the length of the records was the same as for the radar interferometry due to the simultaneous measurements. The sensors were attached using neodymium magnets to the left main steel beam in the cross-section...
7. Numerical Simulation Results In order to verify the applicability of the proposed control scheme for the two-machine drive system of Figure 2, the following simulations are performed using two identical 2-pole, 50 Hz five-phase PMSM. The parameters of each machine are listed in Table 1. ...
The binodal line is determined by identifying the endpoints of these tie lines, which represent the critical composition at which the two coexisting phases become identical. However, some ambiguity exists where the continuity of the phases is influenced not only by the mixture composition but also ...
