In microservice systems, such disruptions can, for example, be caused by continuous deployment, self-adaptation, and various failures. Although transient behavior could be captured in non-functional requirements, little is known of how that is handled in practice. Our objective was to study how architects and engineers approach runtime disruptions, which challenges they face, whether or not they specify transient behavior, and how currently employed tools and methods can be improved. To this end, we conducted semi-structured interviews with five experienced practitioners from major companies in Germany. We found that a big challenge in the industry is a lack of awareness of transient behavior by software stakeholders. Consequently, they often do not consider specifying it in non-functional requirements. Additionally, better tooling is needed to reduce the effort of analyzing transient behavior. We present two prototypes that we developed corresponding to these findings to improve the current situation. Beyond that, the insights we present can serve as pointers for interesting research directions for other researchers.", "isbn" : "9781450391597", "numpages" : "8", "location" : "Bejing, China", "doi" : "10.1145/3491204.3527483", "bibtexKey": "10.1145/3491204.3527483" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2d93a351cbf2cd7378a923d4141a353a5/huebleriac", "tags" : [ "Carbenes","Carbenes;isolation","DFT","ESR","Germanium","acyclic","cyclicAlkylamino","radical","stabilized","transient" ], "intraHash" : "d93a351cbf2cd7378a923d4141a353a5", "interHash" : "6f9a0d63bff80ebb3016d356c59494fc", "label" : "Isolation of Transient Acyclic Germanium(I) Radicals Stabilized by Cyclic Alkyl(amino) Carbenes", "user" : "huebleriac", "description" : "", "date" : "2022-06-15 11:26:56", "changeDate" : "2022-06-15 09:26:56", "count" : 5, "pub-type": "article", "journal": "Journal of the American Chemical Society", "year": "2019", "url": "", "author": [ "Mujahuddin M.

In this contribution, Computational Fluid Dynamics (CFD) is used to predict the hot-spot and top-oil temperatures by applying various boundary conditions during transient states following, which are validated with temperatures measured from an experimental setup. The experimental model, which consists of a disc-type winding with 20 discs and four turns, is divided into 3 passes and equipped with PT-100 temperature sensors. Heating cartridges are installed into each conductor of the winding model to supply the electrical heat losses in the winding turns. In order to consider, the variations of the thermal characteristics of oil, its properties are changed at each time step by increasing the temperature. This investigation takes into consideration the transient thermal behavior of natural cooling method inside winding model at various starting oil temperatures 40 °C and 80 °C. Transient curves of top - oil and hot - spot temperatures are compared to identify the time constants. On evaluating the measurement data, the locations and the temperature time constants of hot - spots at different starting oil temperature are found to be the same. Moreover, it is observed that there is no flow reversal or blockage caused by separation eddies, which can be attributed to low oil flow rate through horizontal channels. Finally, it is noted that the average volume temperatures of conductors and top-oil temperature reach steady state thermal condition over time.", "eventtitle" : "IEEE International Conference on Dielectric Liquids (ICDL 2019)", "venue" : "Roma, Italy", "eventdate" : "23-27 June 2019", "bibtexKey": "noauthororeditor" } ] }
