During the last few years the Australian white goods industry has been involved in a major restructuring and rationalisation program which has resulted in fewer, more efficient manufacturers gaining an opportunity to achieve the cost of scale benefits associated with such a move. Manufacturers who survived this shake-out quickly recognised the need to innovate and produce more cost effective products to stimulate and meet market demand while at the same time fend off local and import competition. As a result there has been significant investment in capital equipment to increase productivity and reduce costs. Meanwhile, smart suppliers recognised the part they could play by developing more cost effective products and providing resource input into customer development projects with assistance in areas such as product design, fabrication techniques and material specification. In this paper it is explained how Lysaght recognized the challenge and approached the new opportunities which have evolved within this market.

The results of 23,228 fingerprick capillary blood glucose tests (the taking of which was coordinates by the Diabetic Association of New South Wales) were reviewed. All non-diabetic persons (n = 860) with a blood glucose result of greater than or equal to 8.0 mmol/L were surveyed and 459 responded (53.4%). The responders were typical of the surveyed group with respect to age and capillary blood glucose level. Sixty-four new cases of diabetes were detected, representing 15.8% of the replies from persons who were not known to have diabetes and 0.28% of the total number of persons screened.

Two approaches in design of space frame structures are outlined and discussed. The kinematic equations for arbitrary large rotation of beams are formulated by means of rotation vectors. This is the so called displacement method. The other approach uses nonlinear computational algorithms. An iteration procedure was developed using initial stiffness matrix and orthogonal load-deformation-states.

Inversion of the Jacobian matrix is the critical step in rate decomposition which is used to solve the so-called “inverse kinematics” problem of robotics. This is the problem of achieving a coordinated motion relative to the fixed reference frame. In this paper a general methodology is presented for formulation and manipulation of the Jacobian matrix. The formulation is closely tied to the geometry of the system and lends itself to simplification using appropriate coordinate transformations. This is of great importance since it gives a systematic approach to the derivation of efficient, analytical inverses. The method is also applied to the examination of geometrically singular positions. Several important general results relating to the structure of the singularity field are deducible from the structure of the algebraic system.

View description>>
A 120m tall building incorporating both in-situ and precast post-tensioned concrete components was instrumented to observe some aspects of its structural behaviour. The instrumentation includes embedded and surface strain and temperature transducers, survey reference points, wind pressure tappings, and anemometers above the roof of the building to measure wind characteristics. The paper describes the strain and deformation instrumentation and method of data acquisition. The measured long-term vertical strains and deformations in one of the columns are presented and are compared with values predicted by two methods which are suitable for use by designers. Reference is made to the results of an extensive materials testing programme the results of which enabled the assessment of methods of prediction for the long-term creep and shrinkage properties of the concrete.

To predict the reliability of structures it is necessary to make reasonable allowances in the assessment for the influence of human error in the design, construction and use of the structure. The present paper deals with an attempt to model mathematically the human errors introduced into the structural design process and the effect they may have on structural safety. Preliminary data collection for use in the model is reported, and an outline of the model being developed is given.

Durability of concrete structures is, despite considerable interest, as yet ill-defined. Methods of classification and quantification of durability of concrete members have recently been outlined in a series of co-authored papers. The application of such methods to structures is outlined. The accumulation of data requires the use of a computer, and methods of transferring data from photographic or television images to storage is discussed. The data is then available for computations, which relate types of deterioration effects to reinforcement and other details. Statistical procedures are introduced to systematise the data, and to permit comparisons to be made between structural members, within the same structure or between structures. The approach should, if successfully applied, allow better measurements of durability to be made, and hence improve techniques of predicting performance, making comparisons between materials and systems, assessing repair procedures and estimating repair costs.
