Parallel parking, in general, is a moderate difficulty maneuver. Moreover, for inexperienced drivers, it can be a stressful situation that can lead to errors such as stay far from the sidewalk or damage another vehicle resulting in traffic tickets that range from simple parking violation to crash-related violations. In this work, we propose a computationally effective approach to perform a collisionfree parallel parking. The method will calculate the minimum parking space needed and then the efficient path for the parallel parking. This method is computationally inexpensive in comparison with the current state of the art. Moreover, it could be used by any car because the parameters needed to perform all computations are taken from the specifications of real cars. Preliminary results of this work were summarized in [1] that was presented at the 15th International IEEE Conference on Intell...

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...

Apparition of abnormal vasculature is common at the first phases of tumor growth. It is known as angiogenesis having the whole process various phases. This is also seen as a random migration of cells that require the flux of blood in order to accomplish the consolidation of tumor. This paper provides a hybrid approach by the which it is assumd that sprouting angiogenesis has a well-defined part that would have to be described by classical electrodynamics. A closed-form model that allows to perform computational simulations is presented. In this manner, while the electrically charged compounds such as ions (cations and anions) are described by Coulomb forces, nano particles can be well described by the diffusion equation. According to the model nanoparticles would interact to ions by generating an electric work to cancel cell-ion interactions at the tubular formation of angiogenesis. With...

Para estimar el impacto de los terremotos en áreas urbanas, los investigadores convencionalmente utilizan modelos simplificados de estructuras urbanas para simulaciones. Sin embargo, los avances recientes en tecnología ahora permiten predicciones de respuesta ante terremotos más precisas a través de modelos de alta fidelidad y gemelos digitales. Los programas convencionales de generación de mallas pueden producir modelos 3D generales, pero no están optimizados para simulaciones urbanas a gran escala, donde el refinamiento de la malla cerca de las interfaces de los materiales es esencial. En este estudio, desarrollamos un método eficiente basado en la triangulación de Delaunay para simulaciones a escala urbana mediante la partición del modelo 3D en subdominios. El método propuesto utiliza de manera integrada la información del modelo de elevación digital y del modelo de veloci...

The daily electric demand in Peruvian National Interconnected System-SEIN- has very particular trend, seasonality and characteristics external effects, a situation that complicates the process of estimating the short-term forecast. The aim of this paper is to formulate and calculate ARIMA models with External Events Analysis to achieve efficient forecasts of electricity demand each day, at total level and broken down by areas of the SEIN. The methodology is based on treating each time series using appropriate statistical-mathematical transformations to achieve stability in variance as regular seasonal averages, parallel external events to try to reach an optimal predictive model ARIMA each area of the electrical system of Peru (Central, South and North) and for each day of the week. The results demonstrate the predictive efficiency. Taking as a quality indicator forecast the Mean Absolut...

The symbiotic relationship between human beings and the environment has evolved in parallel, leaving its mark on the genetic structure of our species and the formulation of social statutes. This convergence is evident in the dynamics of modern life, the functional aspects, and the emotional anchors. Based on the postulates of environmental psychology and design proposals, this article presents a model called “restorative urbanism”, stating that proximity to urban nature is a critical element in the composition and design of urban environments, fostering better perceptions of external habitability and improving individual and collective well-being in biopsychosocial terms through the environmental restoration process, achieving urban-environmental and psychological sustainability. The importance of the proposal lies in its ability to question how the morphological characteristics of t...

En el Perú existen pocos estudios académicos referidos al proceso político del parlamento en la formulación de políticas públicas. Por eso nos propusimos abordar el proceso político respecto del diseño de la política de la descentralización en el Perú. Aunque la otra motivación es mi experiencia como asesor parlamentario en el período que nos ocupa. Una interrogante es ¿por qué se arribó a un diseño de la política de descentralización como el que sigue vigente y por qué sigue inalterable en el tiempo? De allí surgieron las hipótesis sobre la calidad del consenso alcanzado, las capacidades de los legisladores y las debilidades o fortalezas de su diseño. Desde la teoría política abordamos desde el juego político de cómo se deciden las políticas, como alcanzan a formularse producto de interacciones, procesos paralelos, argumentación, persuasión y dentro de fase...

In this work, the design of symmetric OTAs with low transconductance value (nA/V order) and their application in low frequency and low power is presented. For this aim, the series-parallel (S-P) mirrors was used, which divided the differential pair transconductance. With this technique, a 1 nA/V transconductor is reached. Techniques for extend the linear range (hundreds milivolts) of the differential pair will presented too. The Advanced Compact MOSFET Model ACM was used in the design process. These symmetric OTAs designed will be used in active filters with low central frequency, for biomedical applications (EEG signals). The capacitors of this filters are in the picofaradads order, and are off chip. These OTAs and filters were designed in 0.8 um standard technology. These techniques that we will present will be validated through simulation

The research is based on the problems encountered in the production process of companies in the metalworking sector. The problem arises from the low availability of machines in the production process due to working conditions (39.5%), poor maintenance management (40.3%) and poor-quality control (20.2%) that generate low profitability for business. As a solution, Lean Manufacturing tools are implemented to improve the process and increase profitability. The improvement proposal consists of a series of stages: first, the definition of indicators for the measurement of the variables; then, the design and implementation of a pilot in the production process and, in parallel, a simulation system will be designed to evaluate the long-term results. The document concludes that the implementation of the proposed tools will increase the availability of machines and an OEE to 55%, avoiding defective...
