This paper introduces a methodology for incorporating metrics for electric-sector reliability into a global Integrated Assessment Model. Using load, resource availability, and system dispatch data with high temporal resolution, we designed a set of reduced-form constraints that guide investment and usage decisions among power plants in IIASA’s MESSAGE model. The analysis examines how such relia...

In this paper we address the problem of temporal alignment applied to captured communicative gestures conveying different styles. We propose a representation space that may be considered as robust to the spatial variability induced by style. By extending a multilevel dynamic time warping algorithm, we show how this extension can fulfil the goals of time correspondence between gesture sequences ...

A dynamic texture (DT) refers to a sequence of images that exhibit spatial and temporal regularities. The modeling of DTs plays an important role in many video-related vision tasks, where the main difficulty lies in fact how to simultaneously depict the spatial and temporal aspects of DTs. While unlike the modeling of DTs, tremendous achievements have been recently reported on static texture mo...

A quick group search optimizer (QGSO) is an intelligent optimization algorithm which has been applied in structural optimal design, including the hinged spatial structural system. The accuracy and convergence rate of QGSO are feasible to deal with a spatial structural system. In this paper, the QGSO algorithm optimization is adopted in seismic research of steel frames with semi-rigid connection...

The current experiment investigated the effects of a dynamic spatial ability on comprehension of a geoscience text on plate tectonics and the causes of volcanic activity. 162 undergraduates (54% female) from a large public university who had little prior knowledge of this science content area were asked to learn about plate tectonics. Measures of spatial ability and working memory capacity were...

We propose a new class of logics for specifying and model-checking properties of distributed systems Dynamic Epistemic Spatial Logics. They have been designed as extensions of Hennessy-Milner logic with spatial operators (inspired by Cardelli-Caires spatial logic) and epistemic operators (inspired by dynamic-epistemic logics). Our logics focus on observers, agents placed in different locations ...

Texture is an image having repetition of patterns. There are two types, static and dynamic texture. Static texture is an image having repetitions of patterns in the spatial domain. Dynamic texture is number of frames having repetitions in spatial and temporal domain. This paper introduces a novel method for dynamic texture coding to achieve higher compression ratio of dynamic texture using 2D-m...
