Architectural Conservation: Principles and Practice

Architectural Principles in Arthrodesis

a real advance in the surgery of the hip joint and when well performed has uniformly produced a large percentage of successes in the fusion rate. Mr. Brittain's technique has been modified or altered in several respects by others, but the soundness of his principle has generally been accepted without question. The same is true of his scapulo-humeral arthrodesis of the shoulder, although this is...

Safe Architectural Design Principles

This report discusses architectures for safety-critical sysems. The report summarises the existing literature in the area as well as the guidance provided by existing safetycritical system development standards. We discuss the three constituent functions of fault tolerant architectures: error detection, damage assessment and confinement and error recovery. We also consider methods for fault pre...

Symmetry Principles and Conservation Laws

Newtonian physics is characterized by the existence of various conservation laws, that is, principles that tell us that however complicated the interactions among the components making up the system, certain quantities never change. Perhaps the most familiar such law is the conservation of the total mass of the system, or “amount of matter” in it: as described in Feynman, §3, we believe that in...

Architectural Practice and Academic Research

This paper examines one possible relationship of academic research and professional practice. It notes that this issue arises from particular national conditions that are not necessarily shared in different countries. As a result, this relationship is not equally visible or similarly understood, and hence models of research have national and even regional variations that threaten the transferab...
