Slow sensors arise in many applications, including sensing chemical concentrations in tracking of contaminant plumes. Slow sensors are often the cause of poor performance and a potential cause of instability. In this paper, we design a modified extremum seeking scheme to account and exploit slow sensor dynamics. We also consider the worst case, which is sensor dynamics governed by a pure integr...

Near surface air temperature (Ta) is one of the key input parameters in land surface models and hydrological models as it affects most biogeophysical and biogeochemical processes of the earth surface system. For distributed hydrological modeling over glacierized basins, obtaining high resolution Ta forcing is one of the major challenges. In this study, we proposed a new high resolution daily Ta...

Despite its seismic activity, Chile has a large number of heritage buildings built with earth. Their conservation depends on elements such as roofing and foundations, but also the quality renders finishing materials. This study seeks to identify characterize coating systems materials used wall surfaces earthen structures in Limarí valley, Chile, seeking contribute dissemination, promotion, pres...

We present a Lagrangian—Eulerian method with adaptively local ZOOMing and Peak/valley Capturing approach (LEZOOMPC), consisting of advection—diffusion decoupling, backward particle tracking, forward particle tracking, adaptively local zooming, peak/valley capturing, and slave point utilization, to solve three-dimensional advection—diffusion transport equations. This approach and the associated ...

This paper proposes two topics for a high performance fingerprint sensor. A modified capacitive detection circuit of charge sharing scheme is proposed, which shows 40% reduction of power consumption and 90% improvement of difference between a ridge and valley sensing voltage than typical scheme. This paper also proposes an effective fingerprint identification system with hardware unit (thinning...

Large-scale development of electric vehicles (EVs) will have a significant impact on the power grid with their great demand for electric power consumption. It is necessary to design the optimal charging scheme for EVs. In this paper, we propose a centralized and a decentralized scheme of optimal decisionmaking on charging of EVs based on a dynamic pricing model. The objective of both schemes is...

This paper deals with the confrontation between forms of urbanisation Lisbon, Portugal, that extends its fringes over Alcântara Valley. same Valley—topography and hydrography—plays as determinants occupation will assume distinct narratives. gradual process is explained through three narratives about (1) margin driven by industrialisation construction a stigmatised periphery, (2) imposition larg...

Using two MNC dominated electronics clusters in Malaysia, this paper examines the development of human capital from two knowledge and skills acquisition modes – formal education and learning by performing which were dominant in the successful evolution of industrial districts. Ineffective systemic coordination throughout the country from federal institutions has restricted the supply of high te...

abstract a mountain glacier, when it occupies a river valley, immediately begins to change the cross-section and profile of that valley. river valleys in mountain areas tends to have v-shaped profiles. glaciers work to widen as well as deepen their valleys and the typical cross-section of a glacial valley is u-shaped. the u-shaped glacial valley is one of the most characteristic of glacial land...
