CrMoN and CrWN coatings were deposited using closed field unbalanced magnetron sputter ion plating system. The microstructure, preferred orientation, and morphology of coatings were determined by x-ray diffraction analysis and SEM observation. The influences of additional elements on the microstructure, adhesion, mechanic, and tribological properties have been investigated. XRD Results showed that preferred orientation of CrMoN and CrWN coatings obviously changed compared with that of the pure CrN coating. All of the new hard coatings exhibited excellent adhesion due to the gradient interface layer design. By introducing Mo and W elements into the CrN-based structure, the coating hardness had an obvious improvement in comparison with pure CrN coatings. Results also showed the wear resistance of CrMoN and CrWN coatings increased clearly. The steady-state dry friction coefficients of the new coatings measured against a WC-6% Co ball are about 0.3, which were significantly decreased from 0.5 of pure CrN coaing. It is expected that these advantageous properties can enable these new hard coatings for a wide range of applications such as dry high-speed machining.

Grid technology offers the potential for providing secure access to remote services, thereby promoting scientific collaborations in an unprecedented scale. Grid Resource Management: Toward Virtual and Services Compliant Grid Computing presents a comprehensive account of the architectural issues of grid technology, such as security, data management, logging, and aggregation of services, as well as related technologies. After covering grid usages, grid systems, and the evolution of grid computing, the book discusses operational issues associated with web services and service-oriented architecture. It also explores technical and business topics relevant to data management, the development and characteristics of P2P systems, and a grid-enabled virtual file system (GRAVY) that integrates underlying heterogeneous file systems into a unified location-transparent file system of the grid. The book covers scheduling algorithms, strategies, problems, and architectures as well as workflow management systems and semantic technologies. In addition, the authors describe how to deploy scientific applications into a grid environment. They also explain grid engineering and grid service programming. Examining both data and execution management in grid computing, this book chronicles the current trend of grid developments toward a more service-oriented approach that exposes grid protocols using web services standards.

This book constitutes the proceedings of the International Conference on Cognitive Computing, ICCC 2020, held as part of SCF 2020 in Honolulu, HI, USA, in September 2020. The conference was held virtually due to the COVID-19 pandemic. The 8 full and 2 short papers presented in this volume were carefully reviewed and selected from 20 submissions. The papers cover all aspects of Sensing Intelligence (SIJ as a Service (SlaaS). Cognitive Computing is a sensing-driven computing (SDC) scheme that explores and integrates intelligence from all types of senses in various scenarios and solution contexts.
