Investigations into Extending the Linear Modulation Range of Hybrid Three-Level and Five-Level Inverters for Variable Speed Drive Applications
Multilevel inverters (MLIs) are highly sought after for medium to high voltage applications, such as traction drives, fans, blowers, HVDC, and FACTS. These inverters provide numerous benefits over conventional two-level ... -
Computational Approaches to Engineering Antibody Responses to HIV
Efforts are underway to devise interventions that would control HIV infection without the need for lifelong antiretroviral therapy. A key strategy involves the elicitation of endogenous antibodies that can neutralise diverse ... -
Group Testing: A Probably Approximately Correct Analysis and Recovery Algorithms for pooled RT-qPCR
The goal of group testing, also called pool testing, is to successfully identify a set of k defectives from a population of n items using only m (< n) group tests. In each group test, a subset of the n items is tested ... -
Studies of Carbohydrate-Conjugated Anthracenes in Self-Assembly, Bioimaging and Photosensitization
Conjugation of a carbohydrate moiety to an aromatic core leads to glycostructures that possess a high propensity for self-assembly in aq. solutions, driven primarily by π-stacking of the aromatic ring, as well as, the ... -
Adaptation and Characterization of Fossilized Hydrocarbon Gas Turbine Combustor for Operation with Green Fuel(s): Experimental and Numerical Investigation
Decarbonizing energy conversion systems necessitates the adaptation of conventional fossil-fuel-based systems, which have been designed and optimized over the past century for operation with fossilized hydrocarbons, to ... -
Contaminated Site Investigation and Remediation Using Modified Nano Zero Valent Iron Particles
Rapid industrialization has boosted economic growth but also increased contaminants in air, water, and soil. Improper disposal of municipal solid waste and industrial effluents has rendered many groundwater sources unfit ... -
