In this paper, we develop an accurate dynamic thermal management DTM approach considering the interdependency of temperature and leakage. By modeling the leakage-thermal interdependence as a quadratic polynomial, we develop accurate analytical equations that capture the thermal transient. We also identify all the situations in which thermal runaway would occur, which should be avoided by DTM. W...

Dynamic Synchronous Transfer Mode (DTM) is a next generation high speed networking technology. It is based on fast circuit switching and uses distributed channel allocation on shared media. The paper proposes a channel allocation algorithm for DTM, which improves the average call set-up time and call blocking probability characteristics. Another modification is also recommended to the operation...

Cartosat-1 is the eleventh satellite of the Indian Space Research Organisation series and is primarily meant for topographic mapping and Digital Terrain Model (DTM) generation. In the framework of the Cartosat-1 Scientific Assessment Programme, the Politecnico di Milano University (Italy) evaluated as Co-Investigator the performances of the Cartosat-1 satellite in the generation of DTMs. This p...

An algorithm for pose and motion estimation using corresponding features in images and a digital terrain map is proposed. Using a Digital Terrain (or Digital Elevation) Map (DTM/DEM) as a global reference enables recovering the absolute position and orientation of the camera. In order to do this, the DTM is used to formulate a constraint between corresponding features in two consecutive frames....

Hyperthyroidism is recognised as the most common endocrinopathy of older cats, however, despite worldwide occurrence, the pathogenesis of feline hyperthyroidism remains unclear. A number of epidemiologic studies have identified risk factors, however; as yet, none have been shown to cause hyperthyroidism. Traditional methods of managing feline hyperthyroidism include thyroidectomy, anti-thyroid ...

Locking and atomic commitment are two fundamental problems underlying transaction management in fault-tolerant distributed systems. In this paper we discuss these problems in the context of an asynchronous system with replicated objects. We present a generic primitive, named Dynamic-Terminating-Multicast (or DTM) of which instances enable to implement a locking protocol and an atomic commitment...

In this study, the concept of Homotopy analysis method (HAM) is briefly introduced. Furthermore some non-linear problems are handled and the solutions of these problems are given using by HAM, DTM, ADM methods and the convergence of the solution is shown to the exact solution. Additionally, the three methods are compared and it is observed that the HAM is more-less efficient and effective than ...

The increased availability and accuracy of multi-sources data enhance the simulation quality of natural disasters (hazard). Moreover, it enables a better prediction of their impact on the territory (vulnerability). Numerical representation of relief (DTM) is a prime necessity in risk simulation, in particular in flood study. Integrating 2D objects into a DTM significantly improves the relief re...

The flow of an incompressible electrically conducting viscous fluid in convergent or divergent channels under the influence of an externally applied homogeneous magnetic field is studied both analytically and numerically. Navier-Stokes equations of fluid mechanics and Maxwell’s electromagnetism equations are reduced into highly non-linear ordinary differential equation. The resulting non-linear...

We consider the operator A0f = (−1)n 1 v(t) ( Dρ )∗ [ u(t)Dρ ( f (t) v(t) )] , where Dρ f (t) = dk dtk [ ρ(t) dmf (t) dtm ] , ( Dρ )∗ f (t) = dm dtm [ ρ(t) dkf (t) dtk ] , k + m = n. Our main aim is to prove some spectral properties of a natural extension of this operator. In order to prove this we need to prove some properties of a function space, connected to the operator Dρ , and some embedd...
