Optimal part orientation in layered manufacturing using evolutionary stickers-based DNA algorithm

Over recent years, layered manufacturing (LM) has been one of the most important emerging research areas, as well as practice perspective, owing to its capability to reduce the product development time, and therefore time-to-market. In LM, owing to the significant role played by the part orientation in the successful and efficient reduction of the staircase effect, the determination of optimal part orientation is a matter of paramount importance. In this research, the dual parameters problem has been modelled, taking into consideration the constraints pertaining to the rotation of the computer aided design (CAD) model about two axes, while aiming to optimize the objective function that involves layered process error as well as build time. The current paper presents an advanced stickers-based DNA algorithm (SDNA) inspired by the characteristics of deoxyribonucleic acid (DNA) as a tool to achieve the optimal orientation during fabrication of a part. The salient feature of the proposed algorithm is the use of stickers along with DNA memory strand, which are responsible for the representation of information. Moreover, fundamental operations are applied to manipulate the positions of the stickers in essentially all the possible ways. The performance of SDNA has been tested on two standard case studies and the comparisons are made with results obtained from genetic algorithm (GA). The results clearly demonstrate the efficacy of proposed algorithm over GA when applied to the underlying problems.

A structured examination in labour improves documentation

A structured sticker for examination of women in labour was introduced at Arrowe Park Hospital in 1998 to improve documentation of examination findings. This study was undertaken to assess whether the use of the sticker improved documentation of examination findings and second, compliance of sticker use. A retrospective analysis was performed on 64 cases randomised by random number generated on Arcus Quickstat from 470 women who were induced by prostaglandin during 1 January 1998 to 31 December 1998 at Arrowe Park Hospital. Women were induced by prostaglandin were chosen as the study population to obtain data from early labour. A total of 229 examinations were performed in these areas. Statistical analysis was undertaken on Arcus Quickstat, and χ2 and Fisher’s exact tests were applied to check for statistical significance.
