Optimization techniques

Cost-Benefit Analysis (CBA) is an essential tool for economic decision-making, providing a systematic way to evaluate the financial value of projects. It employs mathematical techniques to quantify benefits and costs, enabling decision-makers to compare various options. By translating potential gains and expenses into monetary values, CBA identifies projects that yield the highest net benefits.

To establish a protocol for analyzing NK cell cytotoxic activity (NKAc) in breast cancer patients using the flow cytometric technique. Methods: We first optimized the protocol based on the previously published studies, focusing on choosing fluorescent dye concentration, incubation time length, and Effector:Target cell ratio (E:T ratio). Subsequently, we preliminarily applied the established protocol to characterize NKAc in some breast cancer patients and healthy controls.

This thesis is dedicated to study how the charging behaviours of plug-in hybrid vehicles affect the local distribution network. This study focuses on two issues: the power loss and charging cost optimization. The multi-objective particle swarm optimization technique is applied to achieve the optimal charging schedule, resulting in acceptable additional power loss ratio and charging cost.
