An Analysis with ReMIND
ثبت نشده
چکیده
The present study analyzes the deployment of technologies to reduce CO2 emission in the global energy sector and the implied costs using the energy-economy-climate model ReMIND. The results depend on the policy chosen for inducing changes of investments. Climate policies price emissions and therefore induce changes of investments. The mitigation costs of less than 1% of GDP are relatively small. Targeted technology policies enforce investments for subsets of technologies but do not implement emission pricing. The costs are lower than for climate policies, but the climate target is missed significantly because these policies are subject to CO2 emission rebound effects. The high flexibility of the energy-economy system modeled in ReMIND implies low mitigation costs of climate policies and high rebound effects of technology policies. Technology policies are not sufficient to achieve the climate change mitigation target because coal remains competitive. Climate policies are necessary that target

A redesign of a Visual Programming Language inspected with Cognitive Dimensions of Notations
This report describes a redesign of a process modeling program, reMind. The new design, called reMind+, is presented and evaluated from a usability perspective. reMind lets the user model an industrial process by using a graphical user interface. The model is defined by a node-link diagram, and it is possible to add functions to the nodes. This model is then transferred to a tool that optimizes...

Primary myeloid sacrom (MS) is a rare tumor and even more rare in multiple organs with no evidence of bone marrow involvement. This report describes an unusual case of a 19-year-old male presenting scrotal MS with a history of subconjunctival MS, 5 months ago. Bone marrow biopsies showed no evidence of acute leukemia. Despite radiotherapy for first involvement and chemotherapy for second presen...
متن کاملDynamic Memories: Analysis of an Integrated Comprehension and Episodic Memory Retrieval Model
Most AI simulations have modeled memory retrieval separately from comprehension, even though both activities seem to use many of the same processes. We have developed REMIND, a model that performs both episodic memory retrieval and language understanding with a single spreading-activation mechanism. This approach has a number of advantages over retrieval-only models. First, because the comprehe...
متن کاملREMIND: A Bayesian Framework for Reliable Extraction and Meaningful Inference from Non-structured Data
Existing patient records are a valuable resource for automated outcomes analysis and knowledge discovery. However, key clinical data in these records is typically recorded in unstructured form as free text and images, and most structured clinical information is poorly organized. Time-consuming interpretation and analysis is required to convert these records into structured clinical data. Thus, ...
