Managing death
No full textDrawing on provocative case studies, personal interviews, and detailed research, James Hoefler examines the medical, legal, ethical, and clinical aspects of right-to-die issues. Beginning with the legal struggle of a woman whose son existed in a persistent vegetative state (PVS) for seventeen years, the author moves into a broader look at consensus among professional organizations, from the AMA to the President's Commission to the National Center for State Courts; beliefs of mainstream religious groups; public opinion; issues surrounding end-stage Alzheimer's and other organic brain disorders that can slowly lead to PVS; and the role of artificial nutrition and hydration in these casesHoefler concludes with recommendations on how to improve the quality of right-to-die decisionmaking. An absorbing read with a minimum of technical jargon, this book is a valuable guide to care givers, public policy students, medical ethicists, family members, and anyone facing questions about an individual's right to di
HexaMesh: Scaling to Hundreds of Chiplets with an Optimized Chiplet Arrangement
No full text2.5D integration is an important technique to tackle the growing cost of manufacturing chips in advanced technology nodes. This poses the challenge of providing high-performance inter-chiplet interconnects (ICIs). As the number of chiplets grows to tens or hundreds, it becomes infeasible to hand-optimize their arrangement in a way that maximizes the ICI performance. In this paper, we propose HexaMesh, an arrangement of chiplets that outperforms a grid arrangement both in theory (network diameter reduced by 42%; bisection bandwidth improved by 130%) and in practice (latency reduced by 19%; throughput improved by 34%). MexaMesh enables large-scale chiplet designs with high-performance ICIs
Sparse Hamming Graph: A Customizable Network-on-Chip Topology
No full textChips with hundreds to thousands of cores require scalable networks-on-chip (NoCs). Customization of the NoC topology is necessary to reach the diverse design goals of different chips. We introduce sparse Hamming graph, a novel NoC topology with an adjustable cost-performance trade-off that is based on four NoC topology design principles we identified. To efficiently customize this topology, we develop a toolchain that leverages approximate floorplanning and link routing to deliver fast and accurate cost and performance predictions. We demonstrate how to use our methodology to achieve desired cost-performance trade-offs while outperforming established topologies in cost, performance, or both

Adaptive Routing Strategies for Modern High Performance Networks
No full textToday’s scalable high-performance applications heavily depend on the bandwidth characteristics of their commu-nication patterns. Contemporary multi-stage interconnec-tion networks suffer from network contention which might decrease application performance. Our experiments show that the effective bisection bandwidth of a non-blocking 512-node Clos network is as low as 38 % if the network is routed statically. In this paper, we propose and ana-lyze different adaptive routing schemes for those networks. We chose Myrinet/MX to implement our proposed routing schemes. Our best adaptive routing scheme is able to in-crease the effective bisection bandwidth to 77 % for 512 nodes and 100 % for smaller node counts. Thus, we show that our proposed adaptive routing schemes are able to im-prove network throughput significantly.
Social Validation of INSPIRE Standards Using Online Communities
No full textThis paper describes an approach using online social networks for a participatory, social validation process of INSPIRE Annex III Data Structures in the habitats-related data themes of Sea Regions, Bio-geographical Regions, Habitats and Biotopes, and Species Distribution. Seven European pilot areas dealing with habitats-related data provide the basis for this validation process, which is then supported and facilitated through the use of different social networks. The platform strategy, based on the concept of aggregated communities, is described as well. Various communities provide the basis for involving interested users in the discussion and validation process and thereby help to put the discussions from a local or regional to an international level. The open approach that has been chosen tries to reduce the barriers of participating in the discussions as much as possible in order to discover the real requirements for the pilot areas. Based on these findings, geo-spatial applications are provided to allow for active testing and experimenting as important part of the discussion and validation process.http://enviroinfo.eu/sites/default/files/pdfs/vol6919/0030.pd
Describing typeforms: a designer's response
No full textThe paper sets out an overview of a pragmatic research investigation initiated within a doctoral enquiry, and which continues to inform design practice and pedagogy. Located within the fields of typography and information design, and very much concerned with design history, enquiry emphasized exploration of alternative design research methodologies in the production of a design outcome loaded with pedagogical ambition.
The issue being addressed within the investigation was the limited scope of existing typeface classificatory systems to adequately describe the diversity of forms represented within current type design practice and thus, recent acquisitions to an established teaching collection in London.
Addressing this issue unexpectedly came to utilize the researcher’s own design practice as a methodology for managing emergent enquiry, and for organizing and generating new knowledge through the employment of visual information management methods.
A primary outcome of the enquiry was a new framework for the description of typeforms. This new framework will be described in terms of its operation, divergence from existing models and potential for application
Linked Data Query Wizard: A Novel Interface for Accessing SPARQL Endpoints
No full textIn an interconnected world, Linked Data is more important than ever before. However, it is still quite difficult to access this new wealth of semantic data directly without having in-depth knowledge about SPARQL and related semantic technologies. Also, most people are currently used to con-suming data as 2-dimensional tables. Linked Data is by defi-nition always a graph, and not that many people are used to handle data in graph structures. Therefore we present the Linked Data Query Wizard, a web-based tool for displaying, accessing, filtering, exploring, and navigating Linked Data stored in SPARQL endpoints. The main innovation of the interface is that it turns the graph structure of Linked Data into a tabular interface and provides easy-to-use interaction possibilities by using metaphors and techniques from current search engines and spreadsheet applications that regular web users are already familiar with
