Laser alloying was used for production of thick layers on surface of Nimonic *** laser surface modification,three types of pre-coated pastes were applied:with amorphous boron,with amorphous boron and molybdenum as well as with amorphous boron and *** microstructure,hardness and wear resistance of produced layers were studied in *** presence of different types of borides in re-melted zone depended on the paste composition and caused an increase in hardness up to about HV *** wear resistance was evaluated by calculation of mass wear intensity factor Imw and relative mass loss of specimen and *** wear behavior of the tested frictional pairs was determined by 3D interference microscopy,scanning electron microscopy equipped with EDS *** significant increase in abrasive wear resistance was observed in comparison to untreated Nimonic *** lowest mass loss intensity factor was characteristic of laser-alloyed Nimonic 80A-alloy with boron and niobium(Imw=1.234 mg/(cm2?h)).Laser alloyed-layers indicated abrasive wear mechanism with clearly visible *** alloying with boron and niobium resulted in the additional oxidative wear *** this case,EDS patterns revealed presence of oxygen on the worn surface of specimen.

Mn^4+离子激活的荧光粉在固态照明领域作为红光发射的热点载体正日益受到关注。我们针对当前研究热度撰写了Mn^4+离子光谱学的回顾,并在回顾中聚焦了许多对红色荧光粉商业研制有价值的重要基础研究点。这些研究点涵盖了如何理解自由和晶场状态下Mn^4+离子的能级结构以及Mn^4+发射波长对基质的依赖关系。此外,我们就如何实验调控Mn^4+离子掺杂型荧光粉的发射波长和发光强度给出了许多实际可行的建议。更为重要的是,我们收集并讨论了100多种荧光粉基质中Mn^4+离子光谱学参数,对它们的理解将会为未来Mn^4+掺杂型红色荧光粉的实验开发奠定基础。

The traditional software development model commonly named “waterfall” is unable to cope with the increasing functionality and complexity of modern embedded systems. In addition, it is unable to support the ability for businesses to quickly respond to new market opportunities due to changing requirements. As a response, the software development community developed the Agile Methodologies (e.g., extreme Programming, Scrum) which were also adopted by the Embedded System community. However, failures and bad experiences in applying Agile Methodologies to the development of embedded systems have not been reported in the literature. Therefore, this paper contributes a detailed account of our first-time experiences adopting an agile approach in the prototype development of a wireless environment data acquisition system in an academic environment. We successfully applied a subset of the extreme Programming (XP) methodology to our software development using the Python programming language, an experience that demonstrated its benefits in shaping the design of the software and also increasing productivity. We used an incremental development approach for the hardware components and adopted a “cumulative testing” approach. For the overall development process management, however, we concluded that the Promise/Commitment-Based Project Management (PB-PM/CBPM) was better suited. We discovered that software and hardware components of embedded systems are best developed in parallel or near-parallel. We learned that software components that pass automated tests may not survive in the tests against the hardware. Throughout this rapid prototyping effort, factors like team size and our availability as graduate students were major obstacles to fully apply the XP methodology.

Distribution transformers operating in modern system grids or in industrial networks are subjected to many switching transients,which may occur due to routine operations,network reconfigurations or as reaction on protection *** on the network configuration and parameters,such events may lead to external overvoltages and result in additional stresses on the insulation *** paper presents the influence of a series choke on damping of switching transients in distribution *** impact of the choke is assessed by both amplitude and rise time *** suppression of the transient rise time is shown for a test configuration involving distribution transformers connected to low loss cable lines and a medium voltage *** phenomena are especially typical for industrial networks where switching operations are very *** simulation and experiment results are *** results as well as measurement results confirmed that switching events can lead to high dU/dt and in consequence,can have adverse impacts on insulation *** escalation during switching event is strongly related with system *** results obtained for presented mitigation method are promising and indicate significant dU/dt reduction as well as number of ignitions and voltage peak *** protection of distribution transformers with a series choke is a new approach dedicated to environments prone to the occurrence of transients with high *** results show that the application of serial choke with suitable parameters realizes the reduction of dU/dt at the machines terminal from 24 kV/μs to 5 kV/μs,as well as the reduction of voltage peak value from 10 kV to 5 *** number of ignitions is also reduced.
