Decentralized Applications, or DApps, provide distributed trusted applications that use blockchains. They are often composed of several services, such as transaction scalability protocols, decentralized storage and computing solutions. In order to help formalize these applications, facilitate their development improve interoperability, we propose a novel blockchain Ontology focused on the concepts involving DApps. This ontology extends existing EthOn ontology. It defines key related DApps...

Systems for generating and managing digital identities are in the process of being transformed to improve data sharing security increase decentralization. Addressing both issues, a theoretical solution create manage Self-Sovereign Identities (SSI) is proposed using two Zero-Knowledge Proof (ZKP) protocols based on discrete logarithm difficulty. Automorphism group properties introduced link several identities, their identifiers attributes produce proof. The SSI protocol does not encounter...

With the emerging of many data centers around globe, heavy loads large-scale commercial and scientific applications executed in cloud call for efficient resource management strategies to save energy without compromising performance system throughput. According statistics from Data Centre Dynamic (DCD) organization, expected consumption by computer servers would increase 19% 2013 compared with previous year. Such trend may continue years. Moreover, estimated computers U.S. was about 2% out...

In a collaborative computer-supported engineering environment, the interoperation of various applications will need representation that goes beyond current geometry-based representation, which is inadequate for capturing semantic information. The primary purpose this study to discuss semantically based information exchange protocol facilitate seamless interoperability among and next generation computer-aided design systems (CAD) between CAD other use product data. An ontological approach...

Current solutions for designing and building decentralized blockchain applications lack interoperability. Consequently, blockchains existing technologies do not integrate well in a unified framework. This integration is necessary to work around some of the constraints, such as scalability transactions ergonomics. Indeed, are suitable huge data storage, but there distributed storage that can be used application. Regarding ergonomics, use technology should background transparent users may know...

Conflict management is an unavoidable stage of the collaborative design process. We assume that classifying conflict causes can help prevention as well detection and resolution strategies. Our approach proposes a crossed classification correspondent mitigation strategies implements this in order to enable earlier phases Emphasis put on capture use rationale knowledge mitigation. Based approach, module integrated advanced architecture for concurrent manufacturing presented. A case study...

In the concurrent engineering approach, problems related to product fabrication are taken into account as early possi ble in design process. Manufacturing and assembly process decisive expensive processes conditioning all future steps of industrialisation fabrication. this paper a new method for plan generation, based on concept meta-prod uct, is presented. This designed modern production environments that organised families with multiple op tions variants. Facing combinatory explosion...

Today’s complex design projects require teams of designers to come together facilitate the sharing their respective expertise in order produce effective solutions. Due increasing need for exchanging knowledge, modern are even more structured work with virtual distributed that collaborate over computer networks achieve global optima design. This article presents an architecture where collaborative is synchronously and generically achieved. That is, particular representation models transformed...

With the increased popularity of cloud computing, number and scales data centers have kept growing at unprecedented speeds. In meanwhile, energy consumption by has commensurately increasing as well. Therefore, focus resource management scheduling relatively shifted from mere performance to also efficiency. this paper, we present a novel, Energy-Aware Task Scheduling framework that makes integrated exploitation two well-known saving techniques, DVFS VM Reuse, on task in center. We our...

In a collaborative design environment, various software tools are utilized to enhance the product development. This entails meaningful representation and exchange of data semantics across these different systems. Semantic interoperability information refers enabling intelligence, including construction history, parameters, features, constraints. is crucial difference compared current standards such as STEP that deliver "dumb" geometry, where no intent associated. To enable exchange, we...
