Los medios informativos, tanto los nativos digitales como todavía impresos, son cada vez más activos en redes sociales, ya que permiten una interacción real con sus lectores, ahora también prosumidores. internautas siguen informándose mayoritariamente de la actualidad política a través las cuentas esos medios. En este contexto sorprende que, aunque muchos autores analizan actividad políticos Tw...

The success of Vision Transformer (ViT) in various computer vision tasks has promoted the ever-increasing prevalence this convolution-free network. fact that ViT works on image patches makes it potentially relevant to problem jigsaw puzzle solving, which is a classical self-supervised task aiming at reordering shuffled sequential back their original form. Solving been demonstrated be helpful fo...

One of the major factors influencing variation friction between surfaces in contact is speed; we are faced here with problem determining optimum speed order to improve on mechanical properties and performance entire system. This project investigates experimentally effect rotational (CoF) aluminum disk test samples stainless steel pin using plum oil as a lubricant under thin film lubrication con...

Precise determinations of the image positions in quad gravitational lenses using VLBI can be used to measure the transverse velocity of the lens galaxy and the observer. The typical proper motions are as yr 1 , so the time scale to measure the motion is ten years. By measuring the dipole of the proper motions in an ensemble of lenses we can set limits on the deviation of the inertial frame deen...

We use standard asymptotic notation. That is, f(n) = O(g(n)) implies that there exist constants c, n0, such that for any n ≥ n0, we have f(n) ≤ c · g(n). For example, 10n + 1000 = O(n) holds since we can take c = 100 and n0 = 20. Similarly, f(n) = Ω(g(n)) implies that there exist constants c, n0, such that for any n ≥ n0, we have f(n) ≥ c · g(n). Finally, f(n) = Θ(g(n)) implies that both f(n) =...
