The paper introduces the extraction of objects that are higher than their surroundings, like houses, trees, or bridges, by the segmentation of a DTM (digital terrain model). We propose a new algorithm (called dual rank) to extract the ground in the DTM, which can be seen as an extension of the gray opening. The extraction of high objects can simply be done via thresholding using the preprocesse...

The evolution of fiber optics has made it possible to build high speed communication systems, gigabit (per second) networks. Gigabit networks have enough capacity to integrate traffic from several applications, such as video, audio and computer traffic, into one network. Techniques for gigabit networks, such as packet, cell and circuit switching, have been evaluated at different gigabit testbed...

The dynamic analysis of the biomechanical model of the head load impact using the Differential Transform Method is presented in this paper. In many parts of the world, the problem of traumatic brain injuries (TBI) has led to neurodegenerative dementing disorders and diseases as a result of head load impact from sporting activities, accidents involving the head, etc. have serious effects on huma...

ABSTRACT: Digital terrain models (DTM) have become a commonly used source of data describing the shape of the Earth. Resolution determines the level of details that can be represented in this model. Changing the resolution influences the accuracy of the DTM. The effect of a resolution is even more clearly seen in slope and aspect calculation. Despite the resolution, there are different methods ...

Introduction: Integration science based on KAGUYA and other missions requires spatial registration of different types of data sets. For example, two types of topographic data sets; Digital Terrain Model (DTM) in 10m/pixel based on stereoscopic images of Terrain Camera (TC) in the Lunar Imager/Spectrometer (LISM) and lunar surface profiles in 1km interval derived from Laser Altimeter (LALT). The...

background and objective: molecular epidemiological studies have shown that certain genotypes of mycobacterium tuberculosis (mtb) are over-represented in limited geographical regions, suggesting of evolution of certain genotypes with increasing virulence and pathogenicity. beijing strain of mtb was initially described by its potential to cause outbreaks worldwide and its association with drug r...

The RNA-guided Cas9 system is a versatile tool for genome editing. Here, we established a RNA-guided endonuclease (RGEN) system as an in vivo desired-target mutator (DTM) in maize to reduce the linkage drag during breeding procedure, using the LIGULELESS1 (LG1) locus as a proof-of-concept. Our system showed 51.5%-91.2% mutation frequency in T0 transgenic plants. We then crossed the T1 plants st...

Discrete-time modeling (DTM) dominates the systems engineering literature in the applications of block-oriented modeling. The discrete environment of computer-based process control systems and discrete sampling are the two major reasons [1]. Also, a DTM is easier to obtain because all input changes are approximated by piecewise step input sequences. Nonetheless, DTM has (potentially) two critic...
