The Rochem Separation Systems, Inc. (Rochem) Disc TubeTM Module (DTM) technology is an innovative membrane separation process. It is designed to treat liquid waste that is higher in dissolved solids content, turbidity, and contaminant levels than waste treated by conventional membrane separation processes. According to the technology developer, Rochem, the innovative DTM design reduces the pote...

This paper describes an algorithm which aims at deriving digital terrain models (DTM) from dense digital elevation models (DEM). This algorithm takes place in a processing chain for building detection and modelling in urban areas from high resolution aerial imagery. DEM either come from stereophotogrammetry, or from direct measures such as airborne laser data. DTM are computed as low order freq...

This paper presents the DTM accuracy derived from JERS-1 SAR Interferometry based on the branch cut method. The target area were selected FUJI and FUGEN mountain in the volcanic mountaions. The accuracy of the calculated DTM is that maximum error and R.M.S.E were 217m, and 27.7m respectively. The accuracy weren’t better than theoretical values, but it is regarded as the next factor. (1) satelli...

Introduction: Pyrethroids are important insecticides because of their high activity and low mammalian toxicity. Some studies have demonstrated that these insecticides, especially compounds with an -cyano group, produce toxic effects on various biological systems. Deltamethrin (DTM) is a Type II synthetic pyrethroid insecticide containing -cyano group and is used worldwide in agriculture, ho...

In this study, flapwise bending vibration analysis of a tapered Timoshenko beam mounted on the periphery of a rotating rigid hub is performed. The governing differential equations of motion for pure bending are derived using the Hamilton’s principle and solved using the Differential Transform Method, DTM. During the derivation of the equations, effects of rotary inertia, shear deformation and h...

Nowadays, DTM databases are vital for a variety of applications, such as visualization or terrain analysis. Therefore, in the fields of civil engineering, mapping and geo-information, or geophysics, this data is on the functional route leading from data acquisition to derived applications. One of the main issues when dealing with DTM database representation is data merging, which involves the i...

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...
