We evaluate the performance of an Omnivision OV5647 CMOS image sensor (5 Mp) for detecting radiation from Sr90 and Cs137 sources. Our experimental setup uses a Raspberry Pi 3 mini-computer for data acquisition, with image processing using Python and OpenCV libraries. We specify the necessary settings to convert a standard camera into a particle detector sensitive to electrons and photons, including a two-step background filtering procedure. In addition, we implement the first detailed Geant4 simulation that describes the layered geometry and material composition of a commercial CMOS sensor along with the radioactive sources. To enhance the simulation, we include an algorithm for charge diffusion and conversion of the energy deposited by electrons and photons into ADC counts. Our measurements are presented in terms of cluster size, the maximum ADC signal per cluster, and the number of clu...

A pediatric stander is an adapted piece of equipment whose function is to achieve the vertical position of the child when motor control is inadequate, in other words, when the child cannot stand and control his weight against gravity, having the age to do it. This technical equipment is necessary for patients diagnosed with cerebral palsy who have already acquired head control and initiated trunk control. This product has a high value in Peru. For the generation of this equipment, we will apply a computer editing and design process, we will follow a 5-step process in addition to applying CAD, CAE, and CAM techniques, emphasizing the design optimization method. Finally, we will verify how the application of this methodology, together with computer simulation, allows us to generate a functional, resistant prototype and, in the main point, with optimization in design and acquisition costs.

In this paper, a three-dimensional numerical solution for the bending study of laminated composite doubly-curved shells is presented. The partial differential equations are solved analytically by the Navier summation for the midsurface variables; this method is only valid for shells with constant curvature where boundary conditions are considered simply supported. The partial differential equations present different coefficients, which depend on the thickness coordinates. A semi-analytical solution and the so-called Differential Quadrature Method are used to calculate an approximated derivative of a certain function by a weighted summation of the function evaluated in a certain grin domain. Each layer is discretized by a grid point distribution such as: Chebyshev-Gauss-Lobatto, Legendre, Ding and Uniform. As part of the formulation, the inter-laminar continuity conditions of displacement...

El artículo se centra en la aplicación de tecnología CAD/CAM en la odontología, específicamente en la fabricación de prótesis dentales totales. Este avance ha transformado la forma en que se diseñan y producen estas prótesis, emergiendo la fabricación de ella mediante capas sucesivas a base de tecnologías de impresión 3D como la estereolitografía, el procesamiento digital de luz y la pantalla de cristal líquido. En la presente revisión se profundizó en aspectos clínicos y biomecánicos, evaluando la retención, adaptación de la base, resistencia a la flexión y límite elástico de las prótesis. Los resultados indican que las prótesis digitales ofrecen mejor retención y adaptación en comparación con los métodos convencionales, aunque no hay diferencias estadísticamente significativas en resistencia a la flexión. También se exploraron aspectos económicos, desta...

This article proposes the design of an autonomous navigation system intended for Unmanned Surface Vehicles (USVs) in the form of catamarans with differential propulsion, whose primary function is the collection of plastic waste in aquatic environments such as seas and lakes. The fundamental goal of this system is to optimize the operational capabilities of the USVs by increasing their navigational autonomy, consequently reducing the costs associated with their operation and production. In this context, the vehicle has been mathematically modeled, and a navigation system composed of four essential components has been established. The first component involves heading control, which utilizes GPS and IMU to estimate the orientation of the USV. The second component is the obstacle avoidance system, which employs a lidar sensor. The third component is a collection system that relies on a compu...

Silicon photonics is the leading platform for pho-tonic integrated circuits (PICs) because of its low fabrication cost and a small area on-chip, which allows the forefront of the industry to develop low-energy consuming devices. For the implementation of PICs, among passive devices, the most used because of its functionality is the power splitter. Y-junctions are power splitters that are compact and can deliver relatively wide-band frequency responses. In order to respond to the current demands of silicon photonics foundries, this work proposes a method based on the Particle Swarm Optimization to design always-feasible and mass-production oriented Y-junctions. We have achieved transmittances above 49%, and a flat frequency response in the SCL optical communications band. © 2020 IEEE.

This paper presents an analytical solution for free vibration analysis of thick rectangular isotropic plates coupled with a bounded fluid for various boundary conditions. In order to consider displacement theories of an arbitrary order, the Carrera Unified Formulation (CUF) is used. The eigenvalue problem is obtained by using the energy functional, considering plate and fluid kinetic energies as well as the potential energy of the plate. The Ritz method is used to evaluate the displacement variables, and the functions used in the Ritz series can be adjusted to consider any of the classical boundary conditions. The convergence of the solution is analyzed, and a validation of results considering open literature and 3D finite element software is performed. Parametric studies are carried out to obtain natural frequencies as a function of the side-to-thickness ratio, plate aspect ratio, fluid...

In the age of the Internet, anonymous online users can form a societal reaction by posting large quantities of critique and insulting comments against (perceived) norm violations on social media. These so-called online firestorms, or Enjō in Japanese, tend to include aggressive behavior against the target. This research aims to reveal the dynamics of Enjō and explores how people communicate with each other in the formation process of Enjō by conducting a comparative case study. This study collects tweets posted in five Enjō cases and compares each case to create conceptual categories of the communication process of Enjō. Results show that the participants of Enjō interact with each other to define the problem of concern through exchange of information. Moreover, it is revealed that there are two types of process in the escalation of Enjō, “social problematization” and “villa...
