    Analysis of the Influence of Blaine Numbers and Firing Temperature on Iron Ore Pellets Properties Using RSM-I-Optimal Design: An Approach Toward Suitability

    Cold compressive strength (CCS) and apparent porosity (AP) of pellets are essential properties regarding the burden of blast furnaces. The optimal required values for industries are 2.5 KN CCS and 21% AP. Blai...

    A Low Noise 100 GHz Sideband-Separating Receiver

    We have built a 100 GHz sideband-separating receiver. The receiver, a breadboard for the band 3 cartridges for ALMA, achieves a SSB noise temperature of 6hf/k with a 4–8 GHz IF. We show that it is possible to ...

    Some recent developments in the design of SIS mixers

    SIS mixers in which superconducting tuning elements are integrated with the tunnel junctions have resulted in very low noise heterodyne receivers in the range 68–260 GHz. Above ∼120 GHz the need for extremely ...

    Integrated tuning elements for SIS mixers

    The use of inductive elements to tune out the junction capacitance in SIS mixers is examined. Two new integrated tuning structures are introduced which overcome the limitations of earlier designs.

    Deformation and stresses in different earth models with a rigid core having varying elastic parameters

    In the present paper the small strain theory has been applied to find the stresses and deformation in the interior of the earth models corresponding to different non-uniform density distributions when the elas...
