makeTwin:A reference architecture for digital twin software platform

Digital twin is currently undergoing a significant transformation from the conceptual and theoretical research phase to the implementation and application phase.However,a universally adaptable research and development platform for digital twin is critically needed to meet the development requirements.Specifically,a publicly accessible simulation,testing,and validation platform which can support digital twin model building,data processing,algorithm design,configuration,etc.,is urgently required for researchers.Furthermore,for developers from the industry,a lowcode development platform that can offer a customizable suite of functions such as model creation,data management,protocol configuration,and visualization is urgently needed.Meanwhile,for enterprise users,there is a lack of an application management platform that can be configured and migrated for various application scenarios,functions,and modes.Therefore,based on the system research of digital twin theories and key technologies by the authors(such as the five-dimension digital twin model,digital twin modeling and digital twin data theory,digital twin standards,and so on),a digital twin software platform reference architecture,namely make Twin,is proposed and designed,as well as its ten core functions.The workflow of the make Twin and the interaction mechanisms among its core functions are described.Finally,a digital twin application system for a chemical fiber textile shop floor(CFTS)which was developed according to make Twin,is introduced,which validates the proposed reference architecture.

Teaching Architecture through Design References： The Contribution of Brazilian Journals in the Publication of Visitable Architectures

The aim of this work is to illuminate how the architectural publication in Brazil is influenced by the location of its economic poles. Although the main specialized journals are nationwide read and the published projects are frequently used as design references by students at architecture schools all over Brazil, it appears to be a favor for those projects located at the southeast region. In order to investigate this initial assumption, we selected two of the most influential architectural journals, A U and Project Design magazines, focusing on visitable projects that are, therefore, capable of offering an experience for learning about architectural project. The analysis covered three years of publications in which four states in Brazil were distinguished： Sao Paulo, Rio de Janeiro, Minas Gerais and Federal District. The collected data show that the published visitable projects coincide with the economic poles around centered cities in Brazil, as well as the location of architecture schools and specialized media, becomes evident; not only because of the greater number of projects in the Sao Paulo area, but mainly because most of the published projects are located in the capitals of the analyzed poles.

Building an interoperable space for smart agriculture

The digital transformation in agriculture introduces new challenges in terms of data,knowledge and technology adoption due to critical interoperability issues,and also challenges regarding the identification of the most suitable data sources to be exploited and the information models that must be used.DEMETER(Building an Interoperable,Data-Driven,Innovative and Sustainable European Agri-Food Sector)addresses these challenges by providing an overarching solution that integrates various heterogeneous hardware and software resources(e.g.,devices,networks,platforms)and enables the seamless sharing of data and knowledge throughout the agri-food chain.This paper introduces the main concepts of DEMETER and its reference architecture to address the data sharing and interoperability needs of farmers,which is validated via two rounds of 20 large-scale pilots along the DEMETER lifecycle.This paper elaborates on the two pilots carried out in region of Murcia in Spain,which target the arable crops sector and demonstrate the benefits of the deployed DEMETER reference architecture.
