New death tables

Hospital mortality league tables: influence of place of death.

League tables that rank hospitals according to their death rates are now regularly published in England. The rationale for publication is that differences in death rates may indicate differences in quality of hospital care. Yet a hospital is not only a place for treatment and cure, it is also a place for care of the dying. Currently 55% of all deaths in England occur in NHS hospitals. Provision...

Teaching thermodynamics to engineering students: new approach for interpolation of steam tables

Path-tables of trees: a survey and some new results

The (vertex) path-table of a tree T contains quantitative information about the paths in T . The entry (i, j) of this table gives the number of paths of length j passing through vertex vi. The path-table is a slight variation of the notion of path layer matrix. In this survey we review some work done on the vertex path-table of a tree and also introduce the edge path-table. We show that in gene...

A New Proposal to Fill in the InfiniBand Arbitration Tables

The InfiniBand Architecture (IBA) is a new industry-standard architecture for server I/O and interprocessor communication. InfiniBand is very likely to become the de facto standard in a few years. It is being developed by the InfiniBand Trade Association (IBTA) to provide the levels of reliability, availability, performance, scalability, and quality of service (QoS) necessary for present and fu...

A New DPA Countermeasure Based on Permutation Tables

We propose and analyse a new countermeasure against Differential Power Analysis (DPA) for the AES encryption algorithm, based on permutation tables. As opposed to existing AES countermeasures, it does not use random masking. We prove that our new countermeasure is resistant against first-order DPA; we also show that it is quite efficient in practice.
