Owing to the requirement of surgical senior house officers to prioritise acute admissions in the accident and emergency department, they are increasingly unable to be present in theatre to assist the surgical registrar. As a consequence, the surgeon has to rely on the scrub team to provide much-needed retraction with cases such as open appendicectomies. We have found the use of the Alexis® woun...

Paper cutting is a simple process of slicing large rolls of paper, jumbo-reels, into various sub-rolls with variable widths based on demands risen by customers. Since the variability is high due to collected various orders into a pool, the process turns to be production scheduling problem, which requires optimisation so as to minimise the final remaining amount of paper wasted. The problem hold...

Longwave oscillatory Marangoni convection in a planar binary liquid layer is studied. Finite-amplitude regimes with perturbations of temperature and solute concentration of order unity are considered. Both thermocapillary and solutocapillary effects are taken into account. Oneand two-dimensional patterns on a rhombic lattice are studied and their stability to the perturbations which do not nece...

Active control of low frequency pump noise in water-filled pipes is being developed at AMRL for acoustic signature control on maritime platforms. The present approach is based on separate fluid and wall-axial wave control with collocated control sources. One of the main problems encountered in the design of suitable control sources is their operating effectiveness over a large range of internal...

The functioning of the first type, the flue or labial pipe, was already investigated within previous extensive research projects. The second pipe type, the reed pipe, is less often installed in pipe organs, and only little research was done in this field so far. This is why this pipe type is now the focus of research of the working group ‚Musical Acoustics ‘ at the Fraunhofer Institute for Buil...

In this study, impact test was carried out to assess the condition of prestressed concrete cylinder pipe (PCCP). The impulse response of the test is modeled with system identification approaches. The model of the impulse response can be further used to characterize the deterioration of PCCP. This paper presents preliminary results on the comparison of different models for the response of impact...

This paper gives an example of how predictive models of the deterioration of reinforced concrete pipes and the consequences of failure can be used to develop risk-based replacement strategies for redundant reinforced concrete pipe networks. It also shows how an accurate deterioration prediction can lead to a reduction of agency costs, and illustrates the limitation of the incremental interventi...

Rolls of supercapacitor electrodes have successfully been produced on a pilot paper machine with novel material concept.
