Report of the Working Group on Multispecies Assessment Methods (WGSAM), 9–13 November 2015, Woods Hole, USA
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Three meetings were held between 2013 and 2015 (Stockholm, London and Woods Hole), with progress being made on all the Terms of Reference. WGSAM has been making significant contributions required to enable ICES to develop its capability to give advice on the ecosystem impacts of fishing and climate change. This is a priority area identified in the ICES strategic plan and is consistent with scientific needs to support implementation of the Common Fisheries Policy and Marine Strategy Framework Directive. This final report summarises the key progress made against each ToR. A particularly important area established during this period has been the discussions that have led to guidelines on quality assurance of ecosystem models in-tended for advice giving. WGSAM prepared a specific briefing on this issue and con-tinues to work on issues related to model review processes, model validation and developing methods for generating advice from multi-model ensembles. These are all important areas of work in the evolution toward giving integrated, ecosystem-based advice to ICES clients. We recommend that ICES supports continuation of WGSAM new ToRs and considers more specifically how to support WGSAM in developing advice relevant products.

Theoretical analysis of laser beam cutting
- 2002
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Research is reported into mathematical modelling of the laser cutting process, experimental investigation and an optical system for process monitoring. Following an introduction to laser cutting systems, fundamental physical mechanisms (optical, thermodynamic and fluidic) and chemical mechanisms are explained and each is modelled in isolation. Mathematical process models are then discussed. Experimental results are presented for the influence of process parameters (cutting speed, beam parameters, gas jet parameters) on performance. The influence of different materials (mild and stainless steel, aluminium and copper alloys, polymers, ceramics and composites) on cut surface quality and achievable cutting speed is presented. A brief overview of costs, competing technologies and applications is given.
