This licentiate thesis presents a method for using a high performance network based on circuit switching as a new link level technology for the Internet. The network is called Dynamic synchronous Transfer Mode, DTM, which provides a service based on simplex multirate channels. DTM uses resource reservation and synchronous switching, which gives good real-time support. These features make DTM we...

High speed electronic devices generate more heat than other devices. This chapter is addressing the portable electronic device air cooling problem. The air cooling limitations is affecting the portable electronic devices. The Multi-Core CPUs will dominate the Mobile handsets Platforms in the coming few years. Advanced control techniques offer solutions for the central processing unit (CPU) dyna...

The paper demonstrates modified cross-correlation methods to detect height errors of DTM points based on stereo-pairs of aerial images. The usual cross-correlation method is extended using dynamic dimensioning and different structures of the correlation matrix. Also a texture coefficient is introduced which makes the auto-correlation procedure more robust. All together seven different image mat...

A generic two-dimensional disordered topological superconductor in symmetry class D exhibits rich phenomenology and multiple phases: diffusive thermal metal (DTM), Anderson insulator (AI), quantum Hall (TQH) phase (a superconductor). We numerically investigate the diagram of a lattice model such superconductor, specifically focusing on transitions between phases associated universal critical be...

Thanks to the evolution of new sensors and the development of efficient algorithms, the automatic production of DSM (Digital Surface Models) and DTM (Digital Terrain Models) in urban areas has become possible. At SIRADEL, we have been interested in a new approach using external 3D vectors and a pair of aerial stereo images. In this paper, our method for computing DSM and DTM is briefly presente...

flat, a high accuracy of the DTM is required for tasks such as hydrographic modelling. Airborne lidar (light detection and ranging) has become a standard method for DTM generation in coastal zones. The lidar technique has two main advantages compared to traditional aerial photogrammetry: Firstly, the active laser technique works independently from illumination from the sun, which allows mapping...

A articulação temporomandibular (ATM) encontra-se no nosso rosto e é responsável pelos movimentos de abertura da boca. inflamação ATM gera um distúrbio etiologia multifatorial, que exige uma avaliação multiprofissional tratamento eficaz para o bem-estar do paciente, podendo ser medicamentosa associada a fisioterapia como opção tratamento. Este quadro denominado disfunção (DTM). O objetivo prese...

Meso-scale digital terrain models (DTMs) and canopy-height estimates, or digital canopy models (DCMs), are two lidar products that have immense potential for research in tropical rain forest (TRF) ecology and management. In this study, we used a small-footprint lidar sensor (airborne laser scanner, ALS) to estimate sub-canopy elevation and canopy height in an evergreen tropical rain forest. A f...

Aims – The Drag Temperature Model (DTM) is a semi-empirical model describing the temperature, density, and composition of the Earth’s thermosphere. DTM2013 was developed in the framework of the Advanced Thermosphere Modelling and Orbit Prediction project (ATMOP). It is evaluated and compared with DTM2009, the pre-ATMOP benchmark, and the Committe on Space Research (COSPAR) reference model for a...
