The objective of this work has been to analyze and simulate the interactions of atmospheric and hydrological processes using the WRF Model (Weather Research and Forecasting) in Peru for the year 2014. SENAMHI records precipitation data through a meteorological network found distributed in almost all the Peruvian territory. Due to precipitation has a high spatial variability and to the scarcity of rain gauges, the use of TRMM images was used to estimate precipitation and the WRF atmospheric model to analyze the interactions of atmospheric and hydrological processes during different periods and considering the cumulus parameterizations (Kain-Fritsch scheme, KF) and microphysics (Thompson scheme). Thirty- six images of accumulated monthly precipitation over Peru were processed using the simulation of the atmospheric model WRF (two cases) and the TRMM. Twelve meteorological stations distribu...

El presente trabajo realizó una comparación económica entre dos procesos de licuefacción de gas natural: el primero llamado Preenfriamiento con propano y refrigerante mixto (C3MR), el cual es el proceso más utilizado en el mundo por las plantas de licuefacción de gas natural de gran capacidad; y el segundo denominado proceso Cascada con fluidos mixtos (MFC), el cual es relativamente nuevo pero eficiente energéticamente. Ambos procesos fueron modelados en Aspen Hysys bajo las mismas condiciones de operación y luego optimizados en MATLAB usando el algoritmo genético. Las funciones-objetivo usadas en la optimización fueron: el costo de capital total (CAPEX), los costos operativos (OPEX) y el costo anual de la planta (TAC).

In this investigation it has been evaluated the current situation of the emergency area that assists adults, in a public hospital of Peru. The software Arena was used to perform discreet simulations, with the objective of obtaining improvement proposals that allow reduce the total time of the patient’s permanency in this area before he is to discharge from hospital or admitted in the hospital. A simulation model was developed where several types of patients were identified that were assisted in the surgery, medicine, and traumatología topics. In some cases clinical analysis was required. For reduce the time of a patient’s permanency in the system diverse possibilities were evaluated, being the best alternative a modification in the schedule of the doctors’ attention in the medicine topic. This solution considers that four doctors assist from 7:00 a.m. to 7:00 p.m. and two doctors ...

Peru is in fact a country with important reservoirs of natural gas as Camisea and it opens potential opportunities for gas chemical development. In a mark of a higher enterprise competitiveness, in industry any time is more generalized to account with tools as support for enhanced of process and cost savings. The simulation and optimization of industrial process aided by computer is a powerful alternative. This work has as propose to make the design of a process an economical analysis with preliminary character of an integrated fertilizer complex for several plants: ammonia, nitric acid, ammonia nitrate and urea. The complex to treat the simulation in process where the transformation reactions happen in all steps of the plant, as is the case of nitric acid; it requires a great domain, not alone in the use of a powerful simulator, but a deeper knowledge of reaction kinetics and the thermo...

Debris flows are geophysical phenomena, caused by torrential rain, which occur in mountainous areas, characterized by the detachment of slope and riverbed materials and their consequent dislodge through watersheds and streams. Debris flows usually carry sludge, water and rocks, and can destroy everything in their path. On February 8th, 2019, an event of this type occurred and destroyed Mirave’s community in Peru, which was located in the areas of transport and deposition of debris flows. This research presents the modeling and numerical simulation to reproduce the transport and deposition processes of the debris flow that occurred in Mirave. The initiation process of the debris flow in streams was represented by hydrographs obtained from the estimated rain runoff volumes and solid materials found at each evaluated micro watershed. The numerical simulation results show acceptable result...

This thesis will be oriented in the study of open quantum systems. The transition of processes that go between the Markovian and non-Markovian regime will be studied. The diagnose of non-Markovianity will be made in terms of the variation of the coherence of the state. Accordingly, an optical setup will be implemented that allows us to manipulate certain degrees of freedom, like the polarization and the optical path. Theoretically, we have found that the coherence of the system is transferred to the environment and it decreases as we move a parameter that we will take as time. This situation has been confirmed in the experiment. Then, due to the second part of the setup, which produces a non-Markovian evolution by also changing one of its parameters, we have accomplished the goal of returning the information back into the system and to measure the non-Markovianity of the process.

Research shows that data analysis and artificial intelligence applied to agriculture in Peru can help manage crop production and mitigate monetary losses. This work presents SmartAgro, a system based on pattern mining and classification techniques that takes information from multiple sources related to the agricultural process to extract knowledge and produce recommendations about the crop growth process. The problem we seek to mitigate with our system is the economic losses generated in Peruvian agriculture caused by poor crop planning. Our results show a high accuracy in regards to type of crop recommendation, and a knowledge base useful for agricultural planning.

Objective: To determine if simulation is more effective than conventional exposition in the improvement in nurses’ knowledge of severe preeclampsia. Methods: Crosssectional quasi-experimental study in two private clinics in Cajamarca, Peru. We compared the improvement in nurses’ knowledge of severe preeclampsia: 13 attended to a conventional exposition about severe preeclampsia (Exconv) and 16, the experimental group, had the same exposition and four simulation training sessions (Sim). We conducted a pretest in both groups and a posttest in 20participants; these were composed of multiple choice questions previously validated by experts; Spearman-Brown reliability was 0.76. The simulation training sessions were recorded in video and evaluated by an expert with a checklist adapted from the American College of Obstetricians and Gynecologists. Data was processed with SPSS 20.0. We used S...
