(Final version) Can a Smartphone be specifically identified according to the behavior or actions of the user? Smartphones are nowadays widely used especially due to their numerous functionalities. These devices act like small computers as they have many functions such as internet connection, emailing, chats, social media among others. A lot of traffic is therefore generated from these devices and adversaries may use the traffic to attack the smartphones. Traffic generated by smartphones may be used to interfere with user privacy. Information collected from the traffic can be used to create specific fingerprints that will identify a particular device. This is seen from the two articles reviewed in this paper. Both papers investigate how traffic from a smartphone can be used by attackers to infringe user privacy. Though different methods are used in the studies, the results indicate that user privacy can be infringed.

Alternatives in Dual Energy Radiography data analysis
Alternatives in Dual Energy Radiography data analysis
A dual energy radiography method using basis decomposition was developed, the process to do it is shown and it is compared against an alternate more direct method of analyzing the data using the logarithm of the original data, concluding that this second method does work but it is not better than basis decomposition.

Estudio del proceso termodinámico en una máquina de expreso
Estudio del proceso termodinámico en una máquina de expreso
Estudio de los procesos termodinámicos que conllevan una máquina de expreso. Se utiliza solo agua, sin el filtro de café para utilizar solo la densidad del agua. Se encuentra que es similar a un proceso de Carnot, pero como un ciclo abierto.

Using the One Dimensional Wave Equation to Represent Electromagnetic Waves in a Vacuum
Using the One Dimensional Wave Equation to Represent Electromagnetic Waves in a Vacuum
The differential wave equation can be used to describe electromagnetic waves in a vacuum. In the one dimensional case, this takes the form $\frac{\partial^2\phi}{\partial x^2}-\frac{1}{c^2}\frac{\partial^2\phi}{\partial t^2} = 0$. A general function $f(x,t) = x \pm ct$ will propagate with speed c. To represent the properties of electromagnetic waves, however, the function $\phi(x,t) = \phi _0 sin(kx-\omega t)$ must be used. This gives the Electric and Magnetic field equations to be $E (z,t) = \hat{x} E _0 sin(kz-\omega t)$ and $B (z,t) = \hat{y} B _0 sin(kz-\omega t)$. Using this solution as well as Maxwell's equations the relation $\frac{E_0}{B_0} = c$ can be derived. In addition, the average rate of energy transfer can be found to be $\bar{S} = \frac{E_0 ^2}{2 c \mu _0} \hat{z}$ using the poynting vector of the fields.
