No presente trabalho vamos abordar o Efeito Hall discutindo experimentos realizados afim de estimar o valores do Coeficiente Hall de dois metais,o cobre e o zinco.Com o objetivo de compará-los com o da literatura.

In this paper we will study an algorithm designed by Madgwick which is commonly used to determine the orientation of a quadcopter. The algorithm uses a group of accelerometers, gyroscopes and magnetometers integrated in what is called an IMU as input. Some differences have been found between the results obtained by the original paper and the implementation done by the author. Therefore, a thorough study has been made, finding a miscalculation in the equations. The results show a relative average error in the orientation of 1,44 ppm.

The density of solid water, unlike most molecules, is less than that of its liquid form. Its precise value is of use in many applications. Freezing a spherical droplet of water and analyzing the changed shape from a sphere to a sphere with a slight peak in order to find the density of ice. We find the density of ice to be at 0.90 ± 1.66 · 106 g/mL. The precision of our measurement was limited by uncertainty in the angle measurements of the peak of the droplet.

In this project the behavior of the Faraday cage as an insulator against an induced load, either by an effect of nature as lightning or lightning or power surges be considered. As we know the Faraday cage is a conductor of electric current and therefore theoretically there will be inside a magnetic field or electromagnetic wave in the same way there will be no magnetic field.

his project is part of the FlowNet initiative. FlowNet aims at providing Internet freedom and free flow information through socially informed, censor resistant online social networks. My contribution for FLowNet is in devel- oping an Android application, SecurePost. The requirement for SecurePost is two-fold. First, the system should facilitate secure, anonymous, group communication within a closed group of trusted members. Second, the general public on the Internet viewing this content, should be able to verify that the content was generated only by the said closed group of trusted members. The system consists of an Android client application, a proxy server and a browser-plugin. The OSNs supported by this system are Twitter and Facebook.

L’Internet of Things (IoT), ou l’Internet des Objets (IdO), est considéré comme étant un concept moderne, et à même de révolutionner l’avenir proche. L’intérêt est de créer un environnement composé d’appareils et de systèmes intelligents, pouvant communiquer entre eux par le biais de réseaux informatiques. Ces échanges de données vont ainsi permettre de meilleures prises de décision dans un contexte de plus en plus complexe. Cependant, au fur et à mesure que les échanges se multiplient, la question de sécurité se pose, qui doit prendre en compte la faible puissance de calculs des appareils. Ce document a pour objectif de se focaliser sur les protocoles qui régissent ces échanges, et quelles sont les problématiques de sécurité qui en découlent.

The use of technological resources in education has lead to positive changes in the elaboration of new methodologies, in this context technologies such as the Digital Interactive Whiteboard (DIW) can act by facilitating Learning. The mere presence of the DIW does not guarantee benefits for the student's learning process, that raises doubts about whether or not the resources available are used in a satisfactory manner. In this research it was possible to verify that there are few tools available for the DIW context, and many of them have problems of usability and content quality. Thus, a form of facilitate the content elaboration for the DIW is the use of Authoring Tools (ATs). In order to verify whether or not the use of ATs promotes better use of the DIW, an AT (entitled AtauDIW) was developed to assist the use of DIWs.
