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).

Peru has a fragmented health system, which limits access to its health services because the people seeking medical services can only be treated in specified health centers that are determined by their health insurance. Additionally, this causes each health provider to count and manage their processes and information in an isolated and independent manner. In the Peruvian case, this generates an overload in public health services, since, of the 83.3% of insured nationwide, 73.1% belong to the public sector. Therefore, a process architecture is presented, based on the Zachman framework, that integrates the processes of health services (outpatient, hospitalization and emergencies), as well as an Information Technology (IT) process that supports them. The architecture aims to ensure that level III hospitals in Peru have standardized processes and information, as well as to guarantee their app...

Mathematical modelling applied to batch milling (at experimental level), is a very important tool to simulate and predict the granulometric yield of a given treated ore; this means, for a given duration of milling operation, to obtain an estimate of the corresponding granulometric analysis, which can then be tested with real data later on, to verify the estimates. The model involves the selection and fracture functions depending on each mesh size in the ore distribution. This will allow the prediction of effective and reliable results, saving costs and more importantly, time, without the need to perform the milling process for each prediction of batch milling.

We present the simulation of the application of the Model-based Predictive Control (MPC) of the drum level in a Combined Cycle Plant in order to minimize the time for reaching the highest capacity of plant, around 225 MW. In contrast to others control techniques, our simulation yields that the MPC has shown capabilities as to reach its expected power in about 40 minutes before than PID, time which normally takes the whole industrial process under this control. In the present study, we have tested up to three different reference functions in order to compare performance during the drum level control. According to the simulations, the MPC working together with these reference functions is seen to be promising in the sense of providing efficiency to the plant from the startup until the time when system is reaching 225 MW. We have also calculated a minor discrepancy of order of lees than 5%.

Globalization has intensified competition in many markets. To remain competitive, the companies look for satisfying the needs of customers by meeting market requirements. In this context, Process Capability Indices (PCI) play a crucial role in assessing the quality of processes. In the case of non-normal data there are two general approaches based on transformations (Box-Cox and Johnson Transformation) and Percentiles (Pearson’s and Burr’s Distribution Systems). However, previous studies on the comparison of these methods show different conclusions, and thus arises the need to clarify the differences between these methods to implement a proper estimation of these indices. In this paper, a simulation study is made in order to compare the above methods and to propose an appropriate methodology for estimating the PCI in non-normal data. Furthermore, it is concluded that the best method ...

The service level is a critical factor that affects pharmaceutical enterprises because its focuses on taking care of people's lives. An important factor is fulfilling orders on time to customers (doctors and patients), which requires the availability of products and the highest service level in the health system. The proposal of this study is based on developing a model that integrates supply chain processes at operational level to improve the service level. The model is carried out with the integration of Lean and Agile methodologies that seek to streamline and make the supply chain processes more flexible to fulfill orders. This study was simulated using Arena software, who helps to quantify the operational processes and improvement in the supply chain performance. Lean Agile model achieves the service level required for the industry, as well as improves the performance of the supply c...

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...

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.
