This paper describes an ongoing process to define a suitable process improvement model for story cards based requirement engineering process and practices at agile software development environments. Key features of the SMM (Story card Maturity Model) process are: solves the problems related to the story cards like requirements conflicts, missing requirements, ambiguous requirements, define standard structure of story cards, to address nonfunctional requirements from exploration phase, and the use of a simplified and tailored assessment method for story cards based requirements engineering practices based on the CMM, which is poorly addressed at CMM. CMM does not cover how the quality of the requirements engineering process should be secured or what activities should be present for the requirements engineering process to achieve a certain maturity level. It is difficult to know what is not addressed or what could be done to improve the process. We also presents how can be the identified areas of improvement from assessment can be mapped with best knowledge based story cards practices for agile software development environments.
The production of fenofibrate nanoparticles combining stirred media milling and ultrasonication method was investigated in the current work. The fenofibrate drug sample was first wet milled in stirred media mill for different times and subsequently processed by ultrasonication. The effects of ultrasonication time, power on final product particle sizes were studied. The pre milling by stirred media milling was resulted into reduction of comminution resistance of material. Subsequent treatment by ultrasonication produced smaller particles than obtained by stirred media milling alone. The resulting nanoparticles were found to exhibit excellent stability as investigated by particle size, zeta potential, and multiple light scattering measurement techniques. Further, qualities of nanoparticles obtained by combined approach were characterized by TEM and XRD analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
