高温高压合成Co掺杂ZnO基DMS及其磁性特征

采用高温高压方法将由溶胶-凝胶(Sol-gel)法制备的Co掺杂ZnO基稀磁半导体纳米颗粒置于6GPa压强和1000℃环境中处理,并研究其结构和磁学性质.XRD,XPS以及HRTEM等结构测量和分析表明,在掺杂浓度不高时,Co2 离子被较好地掺杂到了 ZnO晶格中,没有第二相或者团簇存在;而在中高浓度掺杂时,有CoO相形成.SQUID磁性测量显示,样品具有室温铁磁性.     

优势菌混合接种泥炭滴滤塔去除混合硫系

研究了混合菌种接种到泥炭填料塔后,去除混合硫系恶臭H2S、甲硫醚和甲硫醇的情况．筛选自H2S驯化泥炭上的化能硫杆菌Au3和DMS驯化泥炭上的化能硫杆菌Au7混合接种后,对混合气中H2S的去除不变,对MT有一定的去除能力,但对DMS的去除率则不高;接种了筛选自H2S驯化泥炭上的异养型假单胞菌Hm-6和自养型硫杆菌Au7的泥炭生物填料塔,对混合硫系恶臭的去除经历了一个由低到高的过程,去除率最后达到100％,表明Hm-6和Au7混合投加后对恶臭的去除更有效,有着广阔的应用前景。

Short-circuit Analysis in Large-scale Distribution Systems With High Penetration of Distributed Generators

In this paper a short-circuit computation (SCC) procedure for large-scale distribution systems with high penetration of distributed generators based on contemporary technologies is proposed. The procedure is suitable for real-time calculations. Modeling of modern distributed generators differs from the modeling of traditional synchronous and induction generators. Hence, SCC procedures found on the presumption of distribution systems with only traditional generators are not suitable in nowadays systems. In the work presented in this paper, for computation of the state of the system with short-circuit, the improved backward/forward sweep (IBFS) procedure is used. Computation results show that the IBFS procedure is much more robust than previous SCC procedures, as it takes into account all distribution system elements, including modern distributed generators.      

Optimization of the vaporization of flavour components during wort boiling in the brewery by implementing a rectification column

Boiling the wort is an energy‐intensive step during beer production. The central objective of the process is the evaporation of unwanted flavour components, above all the flavour component dimethyl sulphide (DMS). To reduce the required overall evaporation, a recent development involves the insertion of a stripping column into the vapour discharge vent of the wort kettle in which the wort is directed from the kettle against the ascending vapour. The calculation by means of procedural fundamentals and the validation of the process in a large brewery are the subject matter of this article. Process improvement in comparison with conventional boiling systems is documented. Copyright © 2017 The Institute of Brewing & Distilling

DMS—A system for defining and managing human-computer dialogues

As the complexity of human-computer interfaces increases, those who use such interfaces as well as those responsible for their design have recognized an urgent need for substantive research in the human factors of software development. Because of the magnitude of the task of producing software for human-computer interfaces, appropriate tools are needed for defining and improving such interfaces, both in research and in production environments. DMS (dialogue management system) is a complete system for defining, modifying, simulating, executing, and monitoring human-computer dialogues. It is based upon the hypotheses that: (1) dialogue software should be designed separately from the code that implements the computational parts of an application, and (2) different roles are defined for the dialogue author and the programmer to achieve that goal. This paper discusses several of the technical aspects underlying the design of DMS.
