An algorithm for the calculation of transmission zeros of the system (C, A, B, D) using high gain output feedback

IEEE Transactions on Automatic Control, 1978
A new algorithm, which is an extension of [1, algorithm II], is presented to determine the transmission zeros of the system \dot{x}=Ax+Bu, y=Cx+Du denoted by (C,A,B,D) . The algorithm is based on the observation that for nondegenerate (C,A,B,D) systems, the set of transmission zeros of (C,A,B,D) are contained in the finite eigenvalues of the closed ...

Effects of Climate Variability on Malaria Transmission in Southern Côte d’Ivoire, West Africa

2023
Malaria continues to be a major public health concern with a substantial burden in Africa. Even though it has been widely demonstrated that malaria transmission is climate-driven, there have been very few studies assessing the relationship between climate variables and malaria transmission in Côte d’Ivoire.

Transmission electron microscope study of the domain structures associated with the b-, c-, d-, e- and f-reflections in plagioclase feldspars

Contributions to Mineralogy and Petrology, 1974
Ten specimens of plagioclase feldspars (An100 to An25) have been examined by transmission electron microscopy using dark field and direct lattice imaging. The specimens are classified into two groups: (i) those that have been quenched from the melt (synthetic An100, An95, An66 and An50) and (ii) those that have been cooled relatively slowly (An94, An77,

High-Voltage D-C Transmission: General Background and Present Technical Status

IEEE Transactions on Power Apparatus and Systems, 1964
The keys to practical application of high-voltage (HV) direct current for power transmission are the rectifier and inverter, which supply the high voltage required for terminals of the d-c line. The grid-controlled mercury-arc tube with grading electrodes has proved to be a suitable valve in such converters.

Comparison of HIV-1 Mother-to-Child Transmission After Single-Dose Nevirapine Prophylaxis Among African Women With Subtypes A, C, and D

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2006
The HIVNET 012 trial in Uganda showed that mother-to-child transmission (MTCT) of HIV-1 can be prevented by providing pregnant women and their infants with a single dose (SD) of the antiretroviral drug nevirapine (NVP). Safety and efficacy of 1- or 2-dose NVP prophylaxis for prevention of MTCT have been documented in other studies.

Investigations on potential conductors for a D. C. superconducting power transmission line in a 20 meter test bed

IEEE Transactions on Magnetics, 1975
The cryogenic and electrical aspects of a program to evaluate superconductors for a dc superconducting power transmission line are presented. Results for conductors in lengths of 20 meters operated at currents up to 10 kA are described. A battery driven power supply which is capable of delivering and controlling currents upto 50 kA is discussed ...
