This paper focuses on evaluating and optimizing the computation procedures for achieving real-time mapping with modern Airborne Laser Scanning (ALS) instrumentation. The computation steps under consideration include real-time point cloud generation at full resolution, strip-wise analyses of scanning density and coverage, error propagation, ground classification and digital terrain and surface m...

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...

PURPOSE To evaluate in-office dermatophyte test medium (DTM) culture as an alternative to traditional laboratory fungal culture for confirming a diagnosis of onychomycosis, and to determine the prevalence of dermatophytes as a cause of onychomycosis in patients not participating in a clinical trial. DESIGN This nationwide multicenter prospective study enrolled 1100 adult patients with suspect...

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 ...

Long-term hemodialysis patients are prone to an exceptionally high burden of cardiovascular disease and mortality. The novel temperature-based technology of digital thermal monitoring (DTM) of vascular reactivity appears associated with the severity of coronary artery disease in asymptomatic population. We hypothesized that in hemodialysis patients, the DTM and coronary artery calcium (CAC) sco...

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...

The effects of JPEG compression on automated DTM extraction via the approach of feature-based matching are investigated. JPEG lossy compression involves a truncation of higher spatial frequency data, a process which influences the accuracy of computation of grey-value gradients in the feature determination phases of image matching. Resulting accuracy effects on DTM heights obtained via the MATC...

The differential transform method (DTM) is an analytical and numerical method for solving a wide variety of differential equations and usually gets the solution in a series form. In this paper, we propose a reliable new algorithm of DTM, namely multi-step DTM, which will increase the interval of convergence for the series solution. The multi-step DTM is treated as an algorithm in a sequence of ...
