Aqueous biphasic systems (ABS) composed of ionic liquids (ILs) are promising platforms for the extraction and purification of proteins. In this work, a series of alternative and biocompatible ABS composed of cholinium-based ILs and polypropylene glycol were investigated. The respective ternary phase diagrams, tie-lines, tie-line lengths and critical points were determined at 25°C. The extractio...

The hydrated ternary lamellar lipid mixture of dipalmitoyl-PC/dilauroyl-PC/cholesterol (DPPC/DLPC/Chol) has been studied by electron spin resonance (ESR) to reveal the dynamic structure on a molecular level of the different phases that exist and coexist over virtually the full range of composition. The spectra for more than 100 different compositions at room temperature were analyzed by nonline...

This paper utilizes the data generated from Television game shows The Weakest Link to study real life strategic voting with large stake payoffs. Theoretical models are built to analyze the three-player voting possibly with second move of tie breaker. With reasonable specifications, equilibria can be constructed to support all observed outcomes. When the game structure is relatively simple with ...

A new approach to the design of decentralised controllers, using Multi-Objective Evolutionary Algorithm (MOEA), for load-frequency control of interconnected power systems with AC-DC parallel tie-lines and considering Governor Dead Band and Generation Rate Constraint nonlinearities, is proposed in this paper. The HVDC link is used as system interconnection in parallel with AC tie-line to effecti...

Load Frequency control (LFC) in power system is undergoing a lot of changes due to the rapidly growing demand and due to various renewable generation integration to the existing system. This work proposes an LFC scheme based on Fuzzy Logic Control for a hybrid wind-diesel power system. Therefore the objective of this LFC is to minimize system frequency deviations and tie line power changes. The...

Abstract: At present, the common practice in the power system of China is to represent the small and medium hydropower generator group as a negative load. This paper presents a method to build a dynamic equivalent model of the hydropower generator group using a 3rd order generator model and a static characteristic load model. Based on phasor measurements in the tie line which connects to the mo...
