Abstract

Ground movement is responsible for over 60 per cent of structural defects in low‐rise residential properties. Since 1971, insurance companies have been responsible for the significant rectification costs. Repair strategies are currently two‐fold, being determined by whether or not the foundations are underpinned. The Hoopsafe system uses a grid of post‐tensioned concrete beams, cast at foundation level, to restore the structural integrity of the property. The system can provide an alternative to traditional underpinning at an economic cost. Additional benefits include minimal disruption on site and short contract periods; the necessity for homeowners to vacate their properties is usually avoided. These benefits have been demonstrated by illustrative case studies. Professional consultants must consider all options to determine the most effective and appropriate repair technique. The Hoopsafe system can provide an alternative option in the selection process.

The purpose of this paper is to describe a novel error‐ranking methodology and two compensation strategies for hybrid parallel kinematic machines (HPKMs).

Abstract

Purpose

The purpose of this paper is to describe a novel error‐ranking methodology and two compensation strategies for hybrid parallel kinematic machines (HPKMs).

Design/methodology/approach

The paper outlines an error analysis methodology developed for HPKMs and applies the technique to a typical industrial HPKM. Based on the results of this, two compensation strategies are developed and implemented, for both mass‐induced and thermal errors.

Findings

The paper demonstrates and quantifies the performance improvements possible with appropriate error compensation strategies.

Originality/value

The paper introduces a novel and generic methodology for error source analysis and describes two fully implemented compensation strategies which result in a significantly improved level of system performance.

– This paper aims to describe a new methodology for controlling highly flexible automated manufacturing cells for use in aerospace manufacturing and repair.

Abstract

Purpose

This paper aims to describe a new methodology for controlling highly flexible automated manufacturing cells for use in aerospace manufacturing and repair.

Design/methodology/approach

The design methodology and rational of the FLEXA control architecture are described along with it implementation and testing.

Findings

The trials completed so far show that the level of flexibility required can be achieved both at factory, or enterprise level, and at shop floor level.

Practical implications

This work has significant practical implications through its direct applicability for aerospace and other automated manufacturing processes.

Originality/value

The originality of the paper lies in the truly flexible nature of the control system described and its ability to mimic traditional cell control architectures but be expanded through the use of virtual Programmable Logic Controller to control any number of cells without the need for significant extra hardware.

Abstract

On 20 April ISHM‐Benelux held its 1988 Spring meeting at the Grand Hotel Heerlen. This meeting was totally devoted to implantable devices, in particular to the technologies used for these high reliability, extremely demanding devices. For this meeting ISHM‐Benelux was the guest of the Kerkrade facility of Medtronic. Medtronic (headquartered in Minneapolis, USA) is the world's leading manufacturer of implantable electronic devices. Apart from the assembly of pacemakers and heart‐wires, the Kerkrade facility acts as a manufacturing technology centre for Medtronic's European facilities.

Abstract

Presents the writer’s personal review of construction and design of mainly domestic buildings of the Second Millennium. After a brief historical commentary a summary of the main defects the surveyor is likely to encounter in buildings of each period of the millennium is given. The importance of local knowledge is emphasised and as an example the main problems encountered in buildings of the West of England are presented.

Abstract

The 28th annual conference of Aslib, held at Nottingham University from 11th to 14th September, 1953, proved to be the largest that Aslib has so far organized. A list of those present is printed on pp. 254–260. Yet again Aslib was glad to be able to welcome a number of overseas guests and members, including Dr. and Mrs. Lancour and their small daughter from the U.S.A., Drs. and Mrs. van Dijk and Miss Rom from the Netherlands, Mr. M. S. Dandekar and Mr. J. V. Karandikar from India, Miss D. M. Leach from Canada, and Mrs. T. Collin from Norway. Mr. Walter A. Southern, a Fulbright scholar from the U.S.A. affiliated to Aslib during his year's study in the United Kingdom, represented the Special Libraries Association, and Mr. J. E. Holmstrom attended as an observer on behalf of Unesco.
