El Comercio Comunitario antes y después del Brexit: la Unión Europea y el Reino Unido
Lla Unión Europea está viéndose involucrada en una grave crisis política y comercial con uno de sus miembros predilectos, el Reino Unido, debido al Brexit. Veremos la evolución de la Unión Europea y el comercio comunitario, analizaremos de la misma manera los aspectos macroeconómicos del Reino Unido y su comercio, para poder basarnos en términos económicos lo que supone el proceso de salida de la UE, cómo estaba su situación financiera antes y después de estos últimos tres años de incertidumbre.Grado en Comerci
Günther Anders, técnica y apocalipsis
El mundo occidental vive, desde mediados de siglo XX, inmerso en una peculiar conciencia apocalíptica. El presente estudio acude a la obra de uno de esos “profetas” de la era atómica, el filósofo y activista Günther Anders. En torno a su obra, ahondaremos en las relaciones entre la técnica moderna, el apocalipsis y la experiencia del tiempo histórico. Se considerará la cuestión de la técnica moderna como elelemento fundamental de buena parte del pensamiento apocalíptico contemporáneo. La bomba atómica nos servirá como elemento clave de reflexión para entender la experiencia que, desde 1945, tiene la sociedad occidental de su horizonte histórico, de la constitución ontológica del “hombre” y del sentido mismo de la temporalidad
Implementation of a real-time dance ability for mini maggie
The increasing rise of robotics and the growing interest in some fields
like the human-robot interaction has triggered the birth a new generation of
social robots that develop and expand their abilities. Much late research has
focused on the dance ability, what has caused it to experience a very fast
evolution. Nonetheless, real-time dance ability still remains immature in many
areas such as online beat tracking and dynamic creation of choreographies.
The purpose of this thesis is to teach the robot Mini Maggie how to dance
real-time synchronously with the rhythm of music from the microphone. The
number of joints of our robot Mini Maggie is low and, therefore, our main
objective is not to execute very complex dances since our range of action is
small. However, Mini Maggie should react with a low enough delay since we
want a real-time system. It should resynchronise as well if the song changes or
there is a sudden tempo change in the same song.
To achieve that, Mini Maggie has two subsystems: a beat tracking
subsystem, which tell us the time instants of detected beats and a dance
subsystem, which makes Mini dance at those time instants. In the beat tracking
system, first, the input microphone signal is processed in order to extract the
onset strength at each time instant, which is directly related to the beat
probability at that time instant. Then, the onset strength signal will be delivered
to two blocks. The music period estimator block will extract the periodicities of
the onset strength signal by computing the 4-cycled autocorrelation, a type of
autocorrelation in which we do not only compute the similarity of a signal by a
displacement of one single period but also of its first 4 multiples. Finally, the
beat tracker takes the onset strength signal and the estimated periods real-time
and decides at which time instants there should be a beat. The dance
subsystem will then execute different dance steps according to several prestored
choreographies thanks to Mini Maggie’s dynamixel module, which is in
charge of more low-level management of each joint.
With this system we have taught Mini Maggie to dance for a general set
of music genres with enough reliability. Reliability of this system generally
remains stable among different music styles but if there is a clear lack of minimal stability in rhythm, as it happens in very expressive and subjectively
interpreted classical music, our system is not able to track its beats. Mini
Maggie’s dancing was adjusted so that it was appealing even though there was
a very limited range of possible movements, due to the lack of degrees of
freedom.Ingeniería de Sistemas Audiovisuale
Data processing handover in the multi-access edge computing setting
The multi-access edge computing (MEC) technology is a key pillar of the 5th generation (5G) telecommunication network. Among other benefits, it will allow for ultra-low latency communications by bringing computations closer to the user equipment (UE). However, when the UE changes its position, the problem of keeping computations close to it arises. In this work I study this problem related to handover, taking the Megasense project as a real life use case. I propose, implement and analyze a solution that aims at solving the aforementioned problem within a prototype system developed by Nokia Bell Labs
First record of the banjo catfish Bunocephalus doriae Boulenger 1902 (Siluriformes: Aspredinidae) in the Bermejo River basin, Salta, Argentina
Intense sampling in the upper Bermejo River basin revealed the presence of specimens of the aspredinid genus Bunocephalus. After detailed morphological and morphometric analyses specimens were identified as Bunocephalus doriae. This is the first record of any member of the Aspredinidae in the upper Bermejo River basin.Fil: Aguilera, Gaston. Consejo Nacional de Investigaciones Científicas y Técnicas.
