Abstract The power of controlling objects with mind has captivated a popular fascination to human beings. One possible path is employ brain signal collecting technologies together emerging programmable metasurfaces (PM), whose functions or operating modes can be switched customized via on-site programming pre-defined software. Nevertheless, most existing PMs are wire-connected users, manually-c...

Natural disasters can severely impact transportation networks. In the hours and days following a major flooding event, knowing the location and extent of the damage is crucial for incident managers for a number of reasons: it allows for emergency vehicle access to affected areas; it facilitates the efficient rerouting of traffic; it raises the quality and reduces the cost of repairs; and it all...

Soil moisture is an important hydrologic variable that controls various land surface processes. In spite of its importance to agriculture and drought monitoring, soil moisture information is not widely available on a regional scale. However, long-term soil moisture information is essential for agricultural drought monitoring and crop yield prediction. The hydrologic model Soil and Water Assessm...

The development of responsive nanomaterials, nanoscale systems that actively respond to stimuli, is one general goal of nanotechnology. Here we develop nanoparticles that can be controllably triggered to synthesize proteins. The nanoparticles consist of lipid vesicles filled with the cellular machinery responsible for transcription and translation, including amino acids, ribosomes, and DNA cage...

A new ‘growing’ maximum likelihood classification algorithm for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region, Ghana. The delineation algorithm is able to find the land-water boundary from SAR imagery for different weather and environmental conditions. As such, the algorithm allows for remote sensed operationa...

DEFINITION Georegistration is the alignment of an unreferenced image with a geodetically (latitude, longitude, and elevation based) calibrated reference image [1]. In general, this process aligns two images (satellite is the most common, but is not limited to satellite images) and correlating the images to a physical location by examining a set of distinguishable points. Figure 1 shows an examp...

Texture features play a predominant role in land cover classification of remotely sensed images. In this study, for extracting texture features from data intensive remotely sensed image, Gabor wavelet has been used. Gabor wavelet transform filters frequency components of an image through decomposition and produces useful features. For classification of fuzzy land cover patterns in the remotely ...

This paper proposes a technique for three-dimensional reconstruction of an underwater environment from range views acquired by an acoustic camera. The final target of the work lies in improving the understanding of a human operator driving an underwater remotely operated vehicle floating close to an offshore structure. Due to the narrow field of view and the absence of control of the sensor pos...
