Order release in a workload controlled flow-shop with sequence-dependent set-up times

In this paper, we report a simulation study on the role of sequence-dependent set-up times in decision making at the order release level of a workload controlled make-to-order flow-shop. The study evaluates the potential for set-ups savings, dependent on the level of workload in the shop, for two alternative strategies, namely considering set-up times centrally, within the release decision or locally, within the dispatching decision. These strategies are compared and assessed on the basis of two main performance measures namely time in system and standard deviation of the job lateness. Results indicate that the local strategy, which has been traditionally adopted in practice and in most of the studies dealing with sequence-dependent set-up times, does not always give the best results. The release frequency and the shop workload appear critical to the selection of the strategy to adopt, strongly influencing system performance.Fundação para a Ciência e a Tecnologia (FCT)Universidade do Minh

Stress-induced transformation in a Ni-Mn-In alloy and the concomitant change of resistivity

In this work, the influence of mechanical stress on magnetic properties and electric resistance of a Ni-Mn- In alloy was studied. It is shown that compression of Ni-Mn-In polycrystalline specimens brings about a stressinduced martensitic transformation. Optical images recorded in-situ confirmed the formation of a martensitic structure during loading and back-transformation upon unloading. Unloading after deformation of specimens that had experienced compressive strains up to 6%resulted in full recovery of their resistivity and magnetic susceptibility. The sharp increase in the electric resistance caused by the stress-induced transformation opens up new possibilities for Ni- Mn-In alloys to be used as a material for sensors responding to mechanical stress

Global Comparative Study on REDD+ story of change: Supporting district-level jurisdictional approaches in Indonesia

Through a strong partnership with an association of district government, Lingkar Temu Kabupaten Lestari (the Sustainable Districts Association, or LTKL), and earlier efforts to showcase the sustainability progress of subnational jurisdictions, CIFOR has continued its work on jurisdictional approaches to low-emission rural development in Indonesian districts

Proposed EEG measures of consciousness: a systematic, comparative review.

Knowledge of which brain properties are required for consciousness is essential for improving clinical diagnostics and therapy as well as for investigating consciousness per se. The search for such properties has yielded many methods and measures for distinguishing conscious and apparently unconscious brain states. Here, we present a systematic literature review of 255 electroencephalography (EEG)-based measures of consciousness in humans. We show that measures based on signal diversity and event related potentials appear to be the most consistent. Specifically, spectral entropy, Lempel Ziv complexity, and spectral edge frequency, seem most practical, consistent, and reproducible. However, since most studies did not collect current or retrospective subjective reports about experiences, the states of consciousness were usually assessed from behavior. Hence, the ground truth about presence or absence of phenomenological experience in such cases is often uncertain, thus limiting the conclusions that can be drawn. We provide detailed overviews of general categories and specific measures of consciousness, to serve as a basis for further studies and future development

Global Comparative Study on REDD+ story of change: CIFOR’s science on wetlands for Indonesian measurement, reporting and verification and forest reference emission level development

Tropical forested wetlands, including peatlands and mangroves, provide critical environmental services and store 3–5 times more carbon than other tropical forests. However, because these ecosystems are under significant pressure from unsustainable land-use practices, they must be credited in the national forest monitoring and measurement mechanism and integrated into the national policy agend
