a simple, rapid new technique is described for the electrophoresis of hemo­globin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened dur...

In integrated navigation systems Kalman filters are widely used to increase the accuracy and reliability of the navigation solution. Usually, an indirect Kalman filter formulation is applied to estimate the errors of an INS strapdown algorithm (SDA), which are used to correct the SDA. In contrast to that, in the direct Kalman filter formulation total quantities like position, velocity and attit...

In this design an optical ring resonator are embedded between two Horizontal input and output waveguides which has 4 orbitals around the center of the resonator so that each orbital consists of 8 rods with different size in which radius of larger orbitals rods are bigger than radius of smaller orbitals rods. The analysis of simulation results showed the proposed filter has the transmission effi...

In general terms a fabric filter system consists of a porous flexible layer of textile material through which a dusty gas is passed to separate particles from the gas stream. Deposits on the textile are removed periodically by powerful moving and thereby cleaning of the cloth to maintain the pressure drop across the filter within practical operating limits. There are several methods to make the...
