The Development of a Holistic Quality Score Using In-Situ Monitoring of Laser Powder Bed Fusion

Additive manufacturing processes allow for a great degree of flexibility in terms of part production. The process is autonomous once the part has started printing in that the operator generally does not need to intervene until the part is finished. One issue that this introduces, however, is an inability to determine part quality during the printing process. Once a part has started printing, the operator must either wait until the part is finished or regularly check on the part during the print to determine the part quality. Using data gathered from multiple sensors, a quality score can be used to estimate the part quality at any point during the printing process. The development of the score also observed several of the largest contributing ambient factors to both the surface roughness and the part porosity. The largest contributors to quality were the chamber temperature and the oxygen content for the surface roughness and porosity, respectively. Each build characteristic was plotted, and the best fit equations created the quality score. The score generated a zero to one hundred scale that can be easily viewed without intimate knowledge of the process

Dr. Adam Daigneault Testimony to the House Committee on Small Business Subcommittee on Underserved, Agricultural, and Rural Development Hearing on “Sustainable Forestry’s Role in Climate Solutions”

Adam Daigneault, University of Maine E.L. Giddings Associate Professor of Forest Policy and Economics, testified Sept. 29 before a U.S. House of Representatives Committee on Small Business Subcommittee on Underserved, Agricultural, and Rural Development, chaired by Maine Rep. Jared Golden. A focus of the hearing was the role of sustainable forestry and how small businesses across this sector are helping to address climate change. Daigneault, whose research focuses on modelling economic impacts of environmental policy on the forestry and agricultural sectors, spoke about how we can manage U.S. forests for carbon, timber and other ecosystem services, and how we can use natural climate solutions and carbon markets to help forest-dependent economies grow

Optimal Forest Rotations with Environmental Values and Endogenous Fire Risk

This paper develops a model that solves for the optimal economic harvest rotation problem to maximize revenue of an even-aged forest plantation when there is a risk of a catastrophic forest fire. The paper also investigates the feasibility of using fire prone stands for carbon sequestration and estimates the effects that it would have on the optimal management regime and rotation age empirically using a typical Douglas-fir stand in the Pacific Northwest. The model incorporates risk-reducing management practices that allow risk and growth to be endogenous, and the optimal rotation model is solved using numerical simulation techniques. Results show that higher carbon prices increase the rotation length regardless of the probability of fire and that the frequency of risk-reducing management practices increase as the stand approaches the optimal harvest age. Results also indicate that intermediate fuel treatments can provide economical and environmental benefits, even with a high probability of fire.Carbon sequestration, Stochastic risk, Forest management, Optimal rotation, Silviculture, Forest fires, Climate change, Resource /Energy Economics and Policy,

Exchange Rates and the Competitiveness of the US Timber Sector in a Global Economy

This paper examines the competitiveness of the US timber industry under different exchange rate policies using a dynamic optimization model of global timber markets. We assume that exchange rates affect the cost structure of harvesting and managing forests and simulate the model for baseline conditions and four additional exchange rate policies. Two policies consider a strengthening United States dollar scenario and two policies examine weak South American currencies. Recently South America has increased its share of global timber production and is shipping increasing quantities of timber to the Unites States. The results indicate that US competitiveness in the forestry sector is sensitive both to strong US $policies and to the weak currency policies pursued by South American governments. A 20$ compared to all other currencies can reduce harvests by 4 7% in the United States over the next 50 years, while a similar reduction in currency values in South America can reduce U.S. production by around 0.4%. In dollar terms, each additional cubic meter of wood produced in South America due to currency policies can reduce producer surplus in the United States by $100.International Relations/Trade,

Transformación de las políticas de gestión de riesgos en Quebec

En 1996, las lluvias excepcionalmente abundantes que cayeron en la región de Saguenay (Quebec - Canadá) provocaron la ruptura o el desbordamiento de presas, inundaciones, deslizamientos de tierra (más de 1000 en 36 horas) y numerosos cortes de electricidad. Estos eventos repentinos causaron dos muertes, forzaron la evacuación de más de 16.000 personas y generaron perdidas económicas estimadas en aproximadamente un millar de dólares canadienses. Cerca de quince años más tarde se hace un balance de algunas de las principales repercusiones que dichos eventos tuvieron en la manera como el gobierno de Quebec enfrenta estas situaciones. Dos leyes (ley sobre la seguridad de las presas (2000) y la ley sobre la seguridad publica 2001)) y una política (la política nacional del agua, 2002) se inspiraron directamente en las lecciones dejadas por el desastre de Saguenay y son brevemente presentadas en este artículo. Estas lecciones, así como aquellas obtenidas de la tormenta de hielo que vivió Quebec en 1998, abrieron la vía a un enfoque mas global y estructurado de la seguridad civil: la gestión de riesgos.In 1996, unusually heavy rains fell in the Saguenay region (Quebec, Canada) have caused the failure or circumvention of dams, floods, landslides (more than 1000 in 36 hours) and numerous power outages, These hazards have caused two deaths, forced the evacuation of more than 16.000 peoples and generated estimated damage at about 1 billion Canadian dollars, Nearly 15 years later, we present some of the main benefits of these events on the way that the Quebec government deals with such situations, Two laws (Law on Dam Safety (2000) and Public Safety Act (2001)) and policy (the National Water Policy, 2002) are directly inspired by lessons learned from the disaster of the Saguenay and are briefly presented in this paper, These lessons, like those taken from the ice storm occurred in Quebec in 1998, paved the way for a more comprehensive and structured approach of the civil security: the risk management.Fil: Daigneault, R.
