Digital thermal monitoring (DTM) of vascular function during cuff-occlusive reactive hyperemia relies on the premise that changes in fingertip temperature during and after an ischemic stimulus reflect changes in blood flow. To determine its utility in individuals with and without known coronary heart disease (CHD), 133 consecutive individuals (age 54 +/- 10 years, 50% male, 19 with known CHD) u...

Diierent dynamic subgrid scale models, viz. the dynamic model of Germano et al. are evaluated by means of a priori tests. Direct numerical simulation data for fully-developed turbulent and transitional incompressible ows are used. Low correlation is obtained between exact and modeled subgrid scale stresses with the DSM. Conversely, good agreement is found for both the DMM and the DTM, since tho...

In this paper, the Adomian Decomposition Method (ADM) and the Differential Transform Method (DTM) are applied to solve the multi-pantograph delay equations. The sufficient conditions are given to assure the convergence of these methods. Several examples are presented to demonstrate the efficiency and reliability of the ADM and the DTM; numerical results are discussed, compared with exact soluti...

Three different profiles of the straight fin that has a temperature-dependent thermal conductivity are investigated by differential transformation method DTM and compared with numerical solution. Fin profiles are rectangular, convex, and exponential. For validation of the DTM, the heat equation is solved numerically by the fourth-order Runge-Kutta method. The temperature distribution, fin effic...

Experience in digital terrain modelling has shown, that analysis and preparation of the primary data is of great importance both for the productivity and the quality of DTM modelling. The paper presents a semi-automatic procedure to analyze the primary data in a numerical and graphical way. After gross error detection and data structuring using a triangular irregular network (TIN) the density a...

The integration of digital terrain models (DTM) in geographic information systems (GIS) implies automatically an extension of the GIS reference surface and its queryspace. It is trivial that a DTM is the natural boundary representation of theearth's surface. Man-made objects, for instance houses, bridges, dams should be considered in a second step because these objects cannot be represented wel...

This paper proposes a new semi-analytical approach for online time-domain power system simulation. The approach applies the differential transformation method (DTM) to the power system differential equation model to offline derive a semi-analytical solution (SAS) having symbolic variables about time, the initial state and system conditions. When simulation is online needed for a contingency und...

Isolated Dynamic Traffic Management (DTM) measures are widely applied means to improve road network performance. It is well known that the uncoordinated deployment of DTM measures can yield suboptimal, perhaps even counterproductive impacts, in particular in case of non-recurrent conditions. Dynamic coordination of DTM measures (Integrated Network Management) is put forward as one of the promis...

The goal of this study was to analyze the filtering performance of LiDAR data of an algorithm implemented by our group of research. The algorithm is completely automatic and needs only the raw data classified as first and last pulses. It was implemented in the open source software GRASS and it is composed of three functions that have to be launched in sequence: v.lidar.edgedetection, v.lidar.gr...

For a specific chip, the common industry practice is to provide the system designers with the Thermal Design Power (TDP). According to [11], TDP “is the highest expected sustainable power while running known power intensive real applications” and it should be a safe power level in which to run the system. Therefore, manufacturers recommend that the cooling solution should be designed to dissipa...
