A Digital Terrain Model (DTM) is typically used in applications such as environment planning, flood risk evaluation and building detection. A Digital Surface Model (DSM) is usually acquired by LASER scanning or from stereoscopic pairs of aerial or satellite images. By contrast, a direct DTM acquisition traditionally requires more effort on the terrain or for scene object classification and the ...

Data-centric computing becomes increasingly important because of the rapid growth of application data. In this work, we introduce the DTM (Data-Triggered Multithreading) programming model that extends the DTT (Data-Triggered Thread) model and is fully compatible with existing C/C++ programs. The DTM model naturally attaches computation to data. Therefore, the runtime system can dynamically allo...

Digital terrain models (DTM) have been used in soil mapping worldwide. When using such models, improved predictions are often attained with the input of extra variables provided by the use of proximal sensors, such as magnetometers and portable X-ray fluorescence scanners (pXRF). This work aimed to evaluate the efficiency of such tools for mapping soil classes and properties in tropical conditi...

in chemical engineering, several processes are represented by singular boundary value problems. in general, classical numerical methods fail to produce good approximations for the singular boundary value problems. in this paper, chebyshev finite difference (chfd) method and dtm-pad´e method, which is a combination of differential transform method (dtm) and pad´e approximant, are applied for sol...

The DTM host/network adapter uses a dual-ported shared buffer memory on the interface board as in the Van Jacobson “Witless” interface [9]. The host operating system, SunOS, performs all protocol processing in the shared buffer memory and can therefore minimize the number of times data have to be transferred over the host system bus. We give an overview of the DTM host/network adapter hardware ...

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...

This note reports the combined results of several initiatives in creating and surveying complete suites of endgame tables (EGTs) to the Depth to Mate (DTM) and Depth to Conversion (DTC) metrics. Data on percentage results, maximals and mutual zugzwangs, mzugs, has been filed and made available on the web, as have the DTM EGTs.

We examine the utility of Structure from Motion (SfM) point cloud products to generate a digital terrain model (DTM) and estimate canopy heights in a woodland ecosystem in the Texas Hill Country, USA. Very high spatial resolution images were acquired with a Canon PowerShot A800 digital camera mounted on an unmanned aerial system. Image mosaicking and dense point matching were accomplished using...

Dermatophytes fungi are causative agents of dermatophytosis. Surface skin called dermatophytes after the anatomical localization lesions. A total 164 specimens were collected from patients with dermatophytosis (ring worm) distributed into 89/164(54.26%) male and 75/164(45.73%) female. The DTM culture medium was prepared by adding 0.2g phenol red dye to 1 litter PDA medium, utilized short oligon...
