Appropriate energy management strategies (EMSs) have been selected for plug-in hybrid electric vehicles (PHEVs) based on driving-condition recognition (DCR) according to the acquired driving information, so as to minimize the target parameters. With online control and offline optimization, the strategy is suitable for real-time applications and is of great significance to repetitive routes, owing to its simplicity and ease of implementation. This paper aims to identity the DCR-based EMSs, develop efficient EMSs, and invite researchers involved in this field to discover new solutions. This paper presents a comprehensive analysis of EMSs based on DCR in terms of principles, the scope of application as well as their advantages and disadvantages, and provides a thorough survey of the latest progress in EMSs. We concluded that DCR-based EMSs show an improvement in energy saving and the pollutant-discharging effect.

Interactions between particles and bubbles have been cornerstone for the successful applications of froth flotation to the beneficiations of minerals or coal. Particle-bubble interactions are highly physio-chemical processes on the basis of surface science and hydrodynamics. Though these two aspects are deeply interwoven, we focus on the discussions of the effects of turbulence on the interactions between particles and bubbles, i.e., collision, attachment and detachment. It has to be mentioned this effect is not working in one direction and can affect flotation performance in a complicated way. Only when turbulence effects are well understood, flotation processes can be optimised by suitably changing equipment structure or operating parameters. The aim of this paper is to review the most recent progresses in this aspect and to identify the future development in successfully considering turbulence effects on flotation processes.

The college students in engineering can improve their professional level and comprehensive ability through learning the knowledge with philosophical ideas. In the teaching practice on the course of engineering materials, the authors constructed the contents including the ideological and political factors, and linked the philosophy thoughts with the professional education. The main results are as follows. We understand the similarities of engineering materials and life connotation, and clarify the internal relation and interaction mechanism between materials and objective environment through explaining the environmental theory; We know that we should find out the the principal contradiction during the engineering materials selection and life path selection through the contradiction theory; We understand the influence of various factors on the change of material performances and the influence of creative tools on the development of disciplines through the things correlation theory;We recognize that we need to sum up the historical experiences and learn the failure analysis methods to reduce the probability of disaster accidents through the philosophy methodology. Some relevant teaching cases are introduced in this paper.
