Languages for requirements specifications by G. P Randell( Book )

1 edition published in 1992 in English and held by 4 WorldCat member libraries worldwide

This memorandum discusses 11 desirable features that make a requirements specification language a good language. Current languages are assessed to determine which of these features they possess, and where they are lacking. Conclusions are drawn as to the current state of requirements specification languages, and topics for further research are proposed
The growth of short fatigue cracks in an aluminium alloy by Rebecca J Cook( Book )

2 editions published in 1992 in English and held by 3 WorldCat member libraries worldwide

Fatigue tests have been carried out to establish the effects of various constant amplitude and standardised variable amplitude loading sequences on the growth of short and long cracks in 2024-T3 aluminium alloy. In most cases, the growth rates of short cracks were greater than those of long cracks for the same nominal stress intensity factor ranges, and short cracks grew at stress intensity factor ranges below the long crack threshold values. This Report describes and discusses the experimental crack growth results and compares them with predictions based on the FASTRAN crack closure model of Newman. The experimental work reported includes that which represented the United Kingdom contribution to the core programme of the AGARD cooperative programme on short crack growth behaviour
A computer program to calculate growth rates for cracks at notches in regions of residual stress by Rebecca J Cook( Book )

Electrostatic charging of spacecraft in geosynchronous orbit by Andrew J Sims( Book )

2 editions published in 1992 in English and held by 3 WorldCat member libraries worldwide

This Memorandum is a study of the spacecraft charging phenomenon applicable to satellites in geosynchronous orbit. Differential charging of spacecraft surfaces can induce electrostatic discharges which may manifest themselves as 'operational anomalies' or permanent damage to surface features such as solar cells and thermal control surfaces. Understanding of the problem is achieved via laboratory experiments, analysis of data from spacecraft instrumentation and by numerical simulation. Long-term statistical studies are presented for the location of plasma boundaries at geostationary altitude and for the occurrence frequency and intensity of geomagnetic substorms which permits the probability of severe charging conditions to be predicted for future missions. Laboratory experiments are used to demonstrate the importance of bulk and surface conductivity of dielectric materials to the charging process and a sensitivity analysis is employed to investigate the detailed interaction between the plasma environment and spacecraft surface materials. Finally, a study and simulation of charging events observed in geosynchronous orbit is presented

The SWORD multilevel secure DBMS by A. W Wood( Book )

1 edition published in 1992 in English and held by 3 WorldCat member libraries worldwide

SWORD is a multilevel secure relational database management system. It adopts the 'Insert Low' approach to the provision of confidentiality controls, rather than the more commonly adopted technique of 'Polyinstantiation'. This allows SWORD to enforce confidentiality and elementary integrity constraints, such as uniqueness. Special techniques allow a multilevel SWORD database to be created and maintained by untrusted database clients working at a single level. In particular, 'Place Holders' allow fields to be created so that the classification of the field's contents dominates the classification of its existence. The report presents an informal description of SWORD and provides a general discussion of the issues. The reader should be familiar with the technical problems of providing multilevel computer security and some understanding of relational databases would be helpful
