There is no an explicit solution for is proposed problem in 1963 by Lorentz. Generally, this system of differentials equations is solved by the method oftrapezoidal integration with extrapolation of Richardson or by the improved method of Euler. In this work an altemative solution by the method of Runge Kutta Fehlberg ís presented, which requires only six evaluat.ions ofthe function, thus reducing the time ofcalculation.

Sensing drug substances by nanostructures are very important in accordance with the management of targeted drug delivery processes and drug substances detections. Boron nitride (BN), aluminum nitride (AlN), and gallium nitride (GaN) decorated carbon cage (BN-C, AlN-C, and GaN-C) scaffolds were assessed towards sensing the thiamazole (TMZ) drug through the wB97XD/6–31 + G* level of density functional theory (DFT) computations. The singular models were optimized and their combinations to each other were stabilized to obtain the interacting TMZ@Scaffold bimolecular complexes and their corresponding features. The results indicated the existence of non-covalent physical interactions between the substances and their electronic features indicated possibility of sensing function for the investigated scaffolds. Based on the variations of values of adsorption energy and energy gap, the features ...

Earth's behavior comprehension can be achieved by the analysis of Remote Sensing data, but considering the unprecedented volumes of information currently provided by different satellites sensors, the problem can be regarded as a big data problem. Machine learning techniques have the potential to improve the analysis of this type of data; however, most current machine learning algorithms are unable to properly process such huge volumes of data. In the attempt to overcome the computational limitations related to Remote Sensing Big Data analysis, we implemented the K-Means algorithms, a clustering technique, as distributed solution, exploiting the capabilities of cloud computing infrastructure for processing very large datasets. The solution was developed over the InterCloud Data Mining Package, which is a suite of distributed classification methods, previously employed in hyperspectral ima...

In this paper a hybrid scheme given by diffusion equation in conjunction to classical electrodynamics to examine physics-based mechanisms behind the behavior of beta cells, is presented. Particular attention is paid on the scenario by which beta-cell is not able to segregate insulin granules. Thus, a mechanism that would explain anomalies as seen in the lost of functions to segregate granules of insulin, is proposed. In this manner, the main argument of this paper states that the processes previous to the segregation of insulin given by (i) entrance of insulin, (ii) exit of Potassium K+, (iii) entrance of Calcium 2+, and (iv) segregation of insulin belong in only one universal formulation. A pseudo code by which the diabetes disease might be seen as a bug of the biological software of beta cell is proposed. Therefore a scheme capable to fix that bug would constitute a path to alleviate t...

With the increasing popularity of online social networking platforms, the amount of social data has grown exponentially. Social data analysis is essential as spamming activities and spammers are escalating over online social networking platforms. This paper focuses on spammer detection on the Twitter social networking platform. Although existing researchers have developed numerous machine learning methods to detect spammers, these methods are inefficient for appropriately detecting spammers on Twitter due to the imbalance of spam and nonspam data distribution, the involvement of diverse features and the applicability of data mechanisms by spammers to avoid their detection. This research work proposes a novel hybrid approach of the gravitational search algorithm and the decision tree (HGSDT) for detecting Twitter spammers. The individual decision tree (DT) algorithm is not able to address...

Actuators are devices that provides a controlled change in a physical system. They can operate manually, electrically, or by various fluids. Among them, pneumatics actuators have advantages of working with compressible fluids that provides safety and efficient limitations. These are very critical parameters for soft robotics. Rigid actuators are not suitable to substitute muscle functions, hence flexible actuators are appealing. Yet the process to fabricate soft actuators have long iteration until the final product is manufactured and is difficult to design and control due to their natural flexible behavior. 3D printing could be a possible solution. Researchers are exploring feasible solutions with 3D printing material. However, since it’s a new area of research, there is not a large and deep characterization of these materials. This study will focus on the simulation of a hyperelastic...

The need to develop a BCI brain- computer interface system for the control of a robotic arm in Peru arises from the possibility of interconnecting the human nervous system with a robotic or mechatronic system, and using this concept to recover some motor function. Brain Computer Interface (BCI) is a communication system based on the recording of brain signals (EEG). The electroencephalogram is the basis and support of the BCI technology. It is a novel technology that allows human-machine interaction in a virtual or physical environment, through a communication channel between the central nervous system and a robotic device. In recent years, the aforementioned systems have caused the interest of important research centers worldwide.

Este proyecto se orientó al diseño e implementación de un sistema automatizado destinado a clasificar y recolectar granos de quinua en condiciones de laboratorio. Para ello se tomaron como criterios de diferenciación tanto el color (blanco, rojo y negro) como el tamaño (pequeño, mediano y grande). La propuesta surgió como alternativa al procedimiento manual tradicional, el cual suele generar resultados poco confiables debido a su carácter subjetivo, la lentitud del proceso y las limitaciones en precisión. El sistema estuvo compuesto por un dispensador que liberó los granos de manera individual hacia una zona de trabajo con iluminación controlada, donde una cámara ubicada en la parte superior capturó las imágenes para su análisis. A través de un modelo de visión artificial se determinaron las características físicas de cada grano, y posteriormente un soplador lateral, e...

Because bitcoins processes depend on Internet transactions, one can argue that the dynamics of flux and volume of bitcoins might be subject to stochastic instead of a pure determinism event. By knowing that Quantum Mechanics describes well physics in the microscopic level and it is capable to calculate exact measurements of physical observables, we apply the concept of amplitude of probability to model the success probability of any transaction involving the new monetary unit so-called bitcoins. In this manner we focus on the description of the potential transactions using entirely the formalism of quantum mechanics. In addition we use also the concept of Green’s function that appear along the construction of the amplitude. Although not any direct correspondence can exist between the dynamics of flux of bitcoins and the purpose of a quantum theory, the modeling is limited to the extent...

The abundance of dipoles of glucose in the blood stream would give rise to a pushing out of albumin proteins giving origin to the formation of a biolelectric circuit inside renal glomerulus. In the periods of large amounts of glucose and albumin in blood, kidneys might not be able to filter proteins initializing the interaction protein-protein at the renal glomerulus. From this nephrine and albumin interaction can be seen as a capacitor because the anionic and cationic functions of proteins. This paper have paid attention to the physics of renal glomerulus when it is electrically involved due to the presence of albumin that surpasses the different layers of renal glomeulus becoming a strong indicator of the kidney disease.

The prototype performs a classification and distribution of parts according to color and type of material of the pieces. The classification is done by two sensors that depending on the object may or may not be activated depending of the type of piece. A programmable logic controller (PLC) has the function of automatically controlling the entire process through a program. This program allows the distribution of the parts to different ramps where they will be stored. The physical process may be initiated by pressing a button on the prototype, as well as through a button on a computer screen. The display shows not only buttons, you can see in real time what happens in the prototype parts selection.

El presente trabajo consistió en la formulación de un material restaurador dental a base de nanopartículas de hidroxiapatita (HAp) obtenida de la cáscara de huevo de gallina. Para ello se utilizó el método de mecano-síntesis para la preparación de HAp usando como precursor de calcio a la cáscara de huevo, variando el tiempo de molienda y la temperatura de tratamiento térmico. Se utilizaron las técnicas de DRX, FTIR, MEB, EDS, SPOS y CRM para determinar cuáles fueron las condiciones óptimas de preparación, obteniendo que para 16 horas de molienda y 400 °C de tratamiento térmico la HAp resultante consistía en un material puro con tamaño nanométrico, inclusiones de carbonato y mayor tensión elástica interna. A la par, se realizaron simulaciones computacionales mediante cálculos ab-initio para obtener algunas propiedades físicas de manera teórica en dos tipos de HAp: ...
