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...

Gibson scaling and related properties of flame-surface geometry in turbulent premixed combustion are demonstrated using a novel computational model, Deterministic Turbulent Mixing (DTM). In DTM, turbulent advection is represented by a sequence of maps applied to the computational domain. The structure of the mapping sequence incorporates pertinent scaling properties of the turbulent cascade. He...

Disfunção temporomandibular (DTM) é um termo que engloba uma série de problemas afetam a articulação (ATM) e/ou os músculos da mastigação e estruturas associadas. A DTM pode manifestar-se na forma dor face região das ATM, comprometendo significativamente qualidade vida do seu portador. Fundamentada teoria multifatorial DTM, literatura evidencia como fatores causais: trauma, hábitos parafunciona...

A new gait recognition algorithm, the layered time series model (LTSM), is proposed. LTSM is a two-level model which combines the dynamic texture model (DTM) and the hidden Markov model (HMM). A gait cycle is divided into several temporally adjacent clusters and gait features of each cluster are modelled by the DTM. The HMM is built to describe the relationship among the DTMs, which are regarde...
