Calculation of cutoff frequencies in optical fibers for arbitrary profiles using the matrix method
(1981)We here propose a simple numerical procedure to calculate the cutoff frequencies in optical fibers with any arbitrary refractive index profile including discrete numerical data from profile measurement. The cutoff problem ... -
Calix(n)arene-quinone interactions: Molecular recognition of 2,6-naphthoquinone by 5,11,17,23,29,35-hexa-tert-butyl- 37,38,39,40,41,42-hexahydroxycalix(6)arene
(1995)UV, IR and NMR spectral analyses reveal that 2,6-naphthoquinone forms a 1:1 host-guest type of complex with 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41, 42-hexahydroxycalix(6)arene while 1,4-naphthoquinone does not do ... -
CAP-GO computer-aided planning of grinding operations for ferrous components
(1997)The present work is devoted to the development of computer software for selecting the optimal process parameters for grinding of ferrous components. It also includes an optional analysis of the residual stress in the ground ... -
A capacitive pressure gauge as a reliable transfer pressure standard
(1999)This paper describes the performance of an alternative capacitive pressure gauge using lead iron tungstate as a capacitive element over a pressure range of 418 MPa. A commercial strain gauge pressure transducer is used to ... -
Capacitive VAr controllers for induction generators for autonomous power generation
(1996)Self excited induction generators (SEIG) require controllable capacitive VAr to magnetise the machines and compensate the demagnetising effect of loads. Different types of controllers to provide custom power of requisite ... -
The capacity of multi-hop wireless networks with TCP regulated traffic
(2002)We study the dependence of the capacity of multi-hop wireless networks on the transmission range of nodes in the network with TCP regulated traffic. Specifically, we examine the sensitivity of the capacity to the speed of ... -
Capacity of RAKE reception with energy randomization
(2003)We consider a RAKE receiver for coherent binary orthogonal signaling over a frequency selective multipath Rayleigh fading channel. The receiver uses maximal-ratio combining such that the weight estimation errors are not ... -
Cardiac bypass: application of a mechanical heart and lung apparatus
(1995)Deals with the problem of bypass surgery. The authors examine the basic mechanical and physiological problems of the heart and lung. They assume that the cardiopulmonary bypass is a technique by which the pumping action ... -
Cascade of bioreactors in series for conversion of 3-phospho-d-glycerate into d-ribulose-1,5-bisphosphate: kinetic parameters of enzymes and operation variables
(2004)A novel scheme employing enzymatic catalysts is described enabling conversion of d-ribulose-1,5-bisphosphate (RuBP) from 3-phospho-d-glycerate (3-PGA) without loss of carbon. Bioreactors harboring immobilized enzymes namely, ... -
A case for biogas energy application for rural industries in india
(1996)Rural India has a vast potential of biogas eneration and application. During the past two decades. biogas has been promoted mostly as a cooking fuel in the rural areas. According to the prevailing practices in these areas, ... -
Casson fluid flow in a pipe filled with a homogeneous porous medium
(1996)The flow characteristics of a Casson fluid in a tube filled with a homogeneous porous medium is investigated by employing the Brinkman model to account for the Darcy resistance offered by the porous medium. This analysis ... -
