HiPakTM高压SPT IGBT模块的SOA新基准

介绍了电压额定值从2.5kV到6.5kV的新型高压HiPakTMIGBT模块系列.新系列HiPakTM模块采用了ABB最新研制的高压SPT IGBT和二极管,使得其SOA首次达到破纪录的最高极限.新元件的整体电特性都很优异,可以承受如关断和短路这样极端的工作条件.为此,针对给定的电压等级制定了其SOA工作能力的最新基准.     

应用于工业牵引的软穿通IGBT技术的大功率模块

随着1700V-SPT（软穿通）GBT LoPak密集型封装结构模块类型的引入，为了进一步开发利用新的1700V-SPT IGBT和二极管芯片的特性，出现了新的封装类型的模块：即电压1700V，电流额定值为2400A，封装形式的E1和E2工业标准模块。我们在长期高可靠性应用的经验基础上，设计了新的封闭类型，其特性适用于牵引市场。在本文中，讨论了1700V-SPT国IGBT（E1/E2）模块范围的特性，尤其论述了改进的表态和动态特性。     

New Universal All-Digital CPM Modulator

In this paper a new modulator for a broad class of continuous phase modulations (CPM) is proposed that is more flexible and less complex than conventional quadrature modulators, while achieving the same or better performance. Being all-digital it is more suitable for one-chip VLSI implementation. Some design parameters are also discussed and experimental results are presented.     

二合一芯片

由于整合开关器件与反并联二极管这一概念具有难以攻克的技术挑战,因此近年来这一技术仅被用于低功率组件（如IGBT和MOSFET）以及特殊应用。另外,IGCT等大面积双极型器件已经采用了单片集成技术,但其中的IGCT和二：极管需要完全分离的硅区。     

Ground Water Flow Modelling Applications in Mining Hydrogeology

Some specific features and problems of numerical modelling applications in mining environment are briefly discussed and three modelling case studies are presented. Two of the applications are aimed at mine dewatering problems in active coal mines. The first represents the underground hard coal mining region in the Czech part of the Upper Silesian Coal Basin. The second example is focussed on optimisation of the dewatering regime of open pit mining of brown coal in the Most sub-basin of the North Bohemian Coal Basin. The third example describes how mathematical modelling can be applied to solve issues associated with the intensive use of mine waters from the flooded Olsi-Drahonin mine as a source of uranium to shorten the time necessary for the purification of mine waters discharged into watercourses.     

Patterns of symptomatic recovery in psychotherapy.

Using the psychotherapy dosage model in which effect was probability of recovery, this study compared treatment response rates for psychological symptoms. Symptom checklists were administered to 854 psychotherapy outpatients at intake and during treatment. 62 symptoms were grouped into 3 classes on the basis of probit analysis results. Chronic distress symptoms demonstrated the fastest average response rate, whereas characterological symptoms demonstrated the slowest. Acute distress symptoms showed the highest average percentage of patients recovered across doses. A typical outpatient needed about a year of psychotherapy to have a 75% chance of symptomatic recovery. The model holds promise for establishing guidelines for the financing of psychotherapy.

Relation between years of psychotherapeutic experience and conceptualizations, interventions, and treatment plan costs.

In this study we investigated the relation between years of experience and psychotherapists' conceptualizations, interventions, and treatment plan costs. Thirty-eight therapists evaluated two case vignettes containing a psychosocial history and therapy session material. The therapists answered open-ended queries concerning their conceptualizations about the patient, intervention strategies, and treatment recommendations. Independent clinical raters rated the responses, using the Psychotherapy Judgment Rating Scale. Conceptualization and intervention categories associated with the psychodynamic orientation were positively related to years of experience. Categories not associated with the psychodynamic orientation demonstrated negative relations. In contrast to less experienced therapists, the more experienced therapists were more facilitative, rated the patients as more disordered, and recommended more costly treatment plans.

Development of Science Gateways Using QCG — Lessons Learned from the Deployment on Large Scale Distributed and HPC Infrastructures

Today, various Science Gateways created in close collaboration with scientific communities provide access to remote and distributed HPC, Grid and Cloud computing resources and large-scale storage facilities. However, as we have observed there are still many entry barriers for new users and various limitations for active scientists. In this paper we present our latest achievements and software solutions that significantly simplify the use of large scale and distributed computing. We describe several Science Gateways that have been successfully created with the help of our application tools and the QCG (Quality in Cloud and Grid) middleware, in particular Vine Toolkit, QCG-Portal and QCG-Now, and make the use of HPC, Grid and Cloud more straightforward and transparent. Additionally, we share the best practices and lessons learned after creating jointly with user communities many domain-specific Science Gateways, e.g. dedicated for physicists, medical scientists, chemists, engineers and external communities performing multi-scale simulations. As our deployed software solutions have reached recently a critical mass of active users in the PLGrid e-infrastructure in Poland, we also discuss in this paper how changing technologies, visual design and user experience could impact the way we should re-design Science Getaways or even develop new attractive tools, e.g. desktop or mobile-based applications in the future. Finally, we present information and statistics regarding the behaviour of users to help readers understand how new capabilities and functionalities may influence the growth of user interest in Science Gateways and HPC technologies.
