Figure 2 Fabrication process steps for the double-arm DC-contact MEMS actuators: (a) Deposition of Ti/Cr DC bias lines, (b) Ti/Cu bias electrode metal deposition, (c) SiO 2 dielectric layer deposition, (d) Ti/Cu transmission line (CPW) metal formation, (e)
Figure 4 shows the geometry and associated dimensions of the MRA planar inverted-F antenna (PIFA), which operates over five frequency bands of GSM900, GPS1575, GSM1800, PCS1900, and UMTS2100 to achieve the capability of global

The cross-section problem of multiples of canonical line bundles over projective spaces is an important problem called generalized vector field problem. We have an interesting

From a structural realist perspective, improving relations between Turkey and Israel during the 1990s would not be unexpected given that the dynamics of regional politics in the

The model predicts that while both inflation and budget deficits are negatively associated with fiscal discipline, they may be positively associated with monetary discipline, proxied

We perform variational Monte Carlo calculations to show that bosons in a rotating optical lattice will form analogs of fractional quantum Hall states when the tunneling is

Along with rare Mendelian diseases, whole exome sequencing has also been applied to common and complex disorders to identify highly penetrant variants in familial forms of

By using the titles, duration and viewer- assigned ratings of more than two-thousand TED talks, we analyse whether the length of an information stream (talk duration) is related to

For the complexation studies of a series of bis-9-anthrylalkanes with a number of electron acceptors, we have prepared the title compound, (I), and carried out a single-crystal
