maintenance is one of the inseparable parts of each industry and relations between this part and others consist of many dynamics and feedbacks. by this regard systems dynamic is a tool that can be used to analyze this part. in this paper for a company that produces wire and cable, cause and effect (feedbacks) between maintenance and others part are modeled. after creating stock-flow diagram, mo...

The aim is to develop an interactive and iterative translation system able to adapt and improve itself rapidly using user’s feedbacks (collected as translation posteditions). We present a preliminary study in which three methods for integrating feedbacks are tested. The results show that, despite the difficulty to measure the system improvement with automatic metrics (given the small size of ou...

The stabilization of nonholonomic systems have focused a lot of attention this last years [see e.g. survey papers 1, 2], in particular because it fails to exist linearizing feedback transformation or static continuous stabilizing state feedback [3] despite they are open-loop controllable [4]. The two main strategies adopted to stabilize these systems are time-varying feedbacks [see e.g. 5, 6, 7...

POLICY ACTION ON CLIMATE CHANGE IS INFORMED BY CLIMATE MODEL projections as described most recently in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The models used are general circulation models (GCMs), which numerically represent the physical climate system in three dimensions, including the hydrological cycle. These are complemented by recently de...

A four-box model of the tropical climate is used to assess its sensitivity to changes in the relative area of the moist and dry regions and to radiative perturbations. The feedbacks modulating this sensitivity are analyzed , particularly the dynamical feedbacks associated with the surface fluxes. The link between the large-scale circulation and these fluxes is found to play a crucial role in th...

This paper investigates the impact of addition/removal/reweighting edges in a complex networked linear control system. For networks positive edge weights, we show that when adding leads to creation new cycles, these turn may lead instabilities. Dynamically, cycles correspond feedback loops. Conditions are provided under which modified network is guaranteed be stable. These conditions related st...

The impacts of air-sea interactions on the representation of tropical precipitation extremes are investigated using an atmosphere-ocean-mixed-layer coupled model. The coupled model is compared to two atmosphere-only simulations driven by the coupled-model sea-surface temperatures (SSTs): one with 31 day running means (31 d), the other with a repeating mean annual cycle. This allows separation o...

Over the past years, the agent-based modeling approach has emerged as a promising geospatial technique for urban change simulation. In this paper, we review the status of agent-based models for urban land change research, with the emphasis on the issues of how far agent-based models have been implemented to model the real world complexity. For such a purpose, we have identified four features of...

[1] The last glacial inception ( 116 ky ago) has long been used to test the sensitivity of climate models to insolation. From these simulations, atmospheric, oceanic and vegetation feedbacks have been shown to amplify the initial insolation signal into a rapid growth of ice-sheets over the northern hemisphere. However, due to the lack of comprehensive atmosphere-ocean-vegetation-northern hemisp...

Understanding the mechanisms underlying negative plant-soil feedbacks remains a critical challenge in plant ecology. If closely related species are more similar, then phylogeny could be used as a predictor for plant species interactions, simplifying our understanding of how plant-soil feedbacks structure plant communities, underlie invasive species dynamics, or reduce agricultural productivity....
