Security and Privacy Issues in Internet of Medical Things addresses the security challenges faced by healthcare providers and patients. As IoMT devices are vulnerable to cyberattacks, and a security breach through IoMT devices may act as a pathway for hackers to enter hospital networks, the book covers a very timely topic. The incorporation of blockchain in the healthcare environment has given birth to the Internet of Medical Things (IoMT), which consists of a collection of healthcare systems that espouse groundbreaking technologies. Systems consist of inter-linked sensors, wearable technology devices and clinical frameworks that perform explicit, secure machine-to-machine and cloud platform communications. The significance of IoMT in the field of healthcare is undoubtedly a win-win situation for patients through technology enhancements and a collection of analytics that helps in better diagnosis and treatment. Due to higher accuracy levels, IoMT devices are more reliable in reporting and data tracking and help avoid human errors and incorrect reporting.

Euro-Par is an annual series of international conferences dedicated to the p- motion and advancement of all aspects of parallel and distributed computing. th Euro-Par 2009 was the 15 edition in this conference series. Througout the years, the Euro-Par conferences have always attracted high-quality submissions and have become one of the established conferences in the area of parallel and distributed processing. Built upon the success of the annual conferences and in order to accommodate the needs of special interest groups (among the conf- ence participants), starting from 2006, a series of workshopsin conjunction with the Euro-Par main conference have been organized. This was the ?fth year in which workshops were organized within the Euro-Par conference format. The workshops focus on advanced specialized topics in parallel and d- tributed computing. These topics re?ect new scienti?c and technological dev- opments. While the community for such new and speci?c developments is still small and the topics have yet to become mature, the Euro-Par conference o?ers a platform in the form of a workshop to exchange ideas and discuss cooperation opportunities. The workshops in the past four years have been very successful. The number ofworkshopproposalsandthenumberof?nallyacceptedworkshopshavegra- ally increasedsince 2006.In 2008, nine workshopswereorganizedin conjunction with the main Euro-Par conference. In 2009, there were again nine workshop

Grid computing has become a topic of significant interest in the scientific community as a means of enabling application developers to aggregate resources scattered around the globe for solving large-scale scientific problems. This monograph addresses four critical software development aspects for the engineering and execution of applications on parallel and Grid architectures.

A new directive-based language called ZEN is proposed for compact specification of wide value ranges of interest for arbitrary application parameters, including problem or machine sizes, array or loop distributions, software libraries, interconnection networks, or target execution machines. Based on the ZEN language, a novel experiment management tool called ZENTURIO is developed for automatic experiment management of large-scale performance and parameter studies on parallel and Grid architectures. This tool has been validated with respect to functionality and usefulness on several real-world parallel applications from various domains, including theoretical chemistry, photonics, finances, and numerical mathematics.

Depending on the ZENTURIO experiment management architecture a generic optimization framework is built up that integrates general-purpose meta-heuristics for solving NP-complete performance and parameter optimization problems in an exponential search space specified using the ZEN experiment specification language. Finally a timely approach is proposed for modeling and executing scientific workflows in dynamic and heterogeneous Grid environments, introducing an abstract formal model for hierarchical representation of complex directed graph-based workflows.

Thus this monograph contributes to various research areas related to integrated tool development for efficient engineering and high performance execution of scientific applications in Grid environments.
