可视化供应链结构和处理过程增进对mySAP ERP中信息技术类操作的理解(英文)

The following conceptual paper mainly addresses the understanding problem that comes up with teaching business economics and applying this to complex IT-infrastructures and integrated processes within an Enterprise Resource Planning System.Under laboratory conditions,we assume to resolve this lack of understanding during transactional exercises and to confirm pupil's or student's business know-how,while well-evaluated case studies are demonstrated and executed by themselves.To visualize supply chain structures and processes,the authors are presenting a framework for physical LEGO constructions and digital modelling logistic scenarios.

机电一体化培训和教育中的电子移动学习课件开发(英文)

Knowledge is essential for the competitiveness of individuals as well as organizations.Thus the application of the latest methodologies and technologies are utilized to support knowledge acquisition,warehousing,distribution,and transfer.Means and methods of web 2.0 are useful to support this procedure.Especially,highly complex and very dynamic knowledge domains have to be accessible and applicable in the framework of learning network communities,including the stakeholders of training and education.Mechatronics for example is such an interdisciplinary,dynamic field of research and application.Based on intelligence,software,and hardware it is requiring special approaches for developing a courseware based learning and knowledge transfer environment.After defining the specifics of mechatronics education and postgraduate training in the context of e-education,the concepts of the development and utilization of mechatronic courseware can be deduced from e-learning 2.0 and mobile learning facilities,possibilities,and abilities.Mechatronic courseware will be developed by using authoring software and embedding the material into learning management systems with respect to general methods and rules of modern system and software development.As an example,the courseware is used for vocational training and further education especially in cooperation networks of educational institutions and SME.

Tuning and implementation variants of discrete-time ADRC

Practical implementations of active disturbance rejection control(ADRC)will almost always take place in discretized form.Since applications may have quite different needs regarding their discrete-time controllers,this article summarizes and extends the available set of ADRC implementations to provide a suitable variant for as many as possible use cases.In doing so,the gap between quasi-continuous and discrete-time controller tuning is closed for applications with low sampling frequencies.The main contribution of this article is the derivation of three different discrete-time implementations of error-based ADRC.It is shown that these are almost one-to-one counterparts of existing output-based implementations,to the point where transfer functions and coefficients can be reused in unaltered form.In this way,error-based implementations become firmly rooted in the established landscape of discrete-time ADRC.Furthermore,it becomes possible to equip error-based variants with windup protection abilities known from output-based ADRC.

Objective and Subjective Dental Treatment Needs among Nursing Home Residents

Objective: The aim of the study was to analyze oral, dental and denture hygiene, and the current treatment needs in nursing home residents. Design: Cross-sectional design. Setting: Nursing homes in Saxony, Germany. Participants and Intervention: Participating dentists recorded the frequency of oral, dental and denture care, dental treatment needs, and the request for treatment in 11,144 nursing home residents by using standardized checklists. Results: Mean age of the residents was 82.5 years, and 74.6% were females. For 54.0% of those examined, nursing staff did care for oral, dental, and denture hygiene. 77.5% of the residents performed oral hygiene more frequently than once daily, 19.8% only once a day, and 2.6% performed oral hygiene less frequent. A need for dental treatment was identified in 64.1% of the residents, of which 34.5% were missing dentures, and 29.7% suffered from dental diseases. 58.3% of the residents not requesting treatment had a clinical need for dental therapy. Objective and subjective need for treatment correlated positively (p < 0.001). Conclusion: Nursing home staff should be aware of the poor oral hygiene and health care conditions in residents. In addition to regular dental check-ups, nursing home residents should be given advice on dental care. Furthermore, dentists and health insurances should develop an action plan to improve oral health of nursing home residents, and to reduce additional costs due to lack of dental care.

Transfer function analysis and implementation of active disturbance rejection control

To support the adoption of active disturbance rejeetion control(ADRC)in industrial practice,this article aims at improv-ing both understanding and implementation of ADRC using traditional means,in particular via transfer functions and a frequency-domain view.First,to enable an immediate comparability with existing classical control solutions,a realizable transfer function implementation of continous-time linear ADRC is introduced.Second,a frequency-domain analysis of ADRC components,performance,parameter sensitivity,and tuning method is performed.Finally,an exact implementation of discrete-time ADRC using transfer functions is introduced for the first time,with special emphasis on practical aspects such as computational fficiency,low parameter footprint.and windup protection.

ADRC in output and error form:connection,equivalence,performance

In this work,we investigate two specific linear ADRC structures,namely output-and error-based.The former is considered a“standard”version of ADRC,a title obtained primarily thanks to its simplicity and effectiveness,which have spurred its adoption across multiple industries.The latter is found to be especially appealing to practitioners as its feedback error-driven structure bares similarities to conventional control solutions,like PI and PID.In this paper,we describe newly found connections between the two considered ADRC structures,which allowed us to formally establish conditions for their equivalence.Furthermore,the conducted comprehensive performance comparison between output-and error-based ADRCs has facilitated the identification of specific modules within them,which can now be conveniently used as building blocks,thus aiding the control designers in customizing ADRC-based solutions and making them most suitable for their applications.
