We proposed an ultra-broadband reflective metamaterial with controlling the scattering electromagnetic fields based on a polarization convertor. The unit cell of the polarization convertor was composed of a three layers substrate with double metallic split-rings structure and a metal ground plane. The proposed polarization convertor and that with rotation angle of 90 deg had been employed as th...

In this paper, a number of mechanisms are described that can be used in the design of a protocol convertor for authentication and key distribution protocols. First, the scope of the mechanisms is deened: we mark out the class of authentication systems that were considered during the design of the mechanisms. A rst mechanism, based on proxies and a synchronization protocol , allows for a transpa...

This paper displays a new access for determining the powerful firing signals for suppression of oscillations by using Optimized PI Based Interline Power Flow Controller [IPFC] through Nonlinear Control Design Block set. The IPFC performance is tested with Proportional Integral Gain [PI] controllers in comparison with Power Oscillation Damping controller [POD] on Modified Phllips-Heffron Model o...

This paper deals with the optimization of the catalytic convertor for CNG Lean burn Engine based on BS4 compliances. In addition to the present catalytic convertor the work is carried out for the optimization of catalytic convertor and also to meet the BS4 compliance and also to reduced cost for the same. In this project we have prepared the samples with some variation in the substrate with res...

Variable characteristics of turbine for different wind speeds have different operating point. Maximum power thus can’t be assured at all points of operation. But MPPT algorithm pushes the electronic dc-dc convertor to provide higher power output by adjusting duty cycle of buck/boost convertor connected before load. MATLAB simulations have been investigated and results show a higher power output...

A47934, a peptide antibiotic produced by Streptomyces toyocaensis, belongs to the glycopeptide class of compounds which includes ristocetin and vancomycin. Incorporation studies with radioisotope-labeled substrates indicated that tyrosine, p-hydroxyphenylglycine, p-hydroxyphenylglyoxylate, acetate, and sulfate were efficiently incorporated into A47934. This is consistent with the reported biosy...

Iron deficiency is most widespread among plant nutrients. Nowadays, different materials such as inorganic salts, organic chelates, soil acidifying materials and industrial wastes are used to correct iron deficiency. Slag and convertor sludge of steel factories are among the industrials wastes for this purpose. These materials contain considerable amount of iron produced in large quantities ever...

The photocell is a silicon photodiode integrated onto a chip together with a voltage-tofrequency convertor. This combination makes a light intensity-to-frequency convertor which has a linear dynamic range of six decades. The light intensity can then simply be determined by counting the frequency. The sensitive area is about two millirrietres square and the band of light produced by the cylindri...
