    Planeación estratégica de la manufactura
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-11-01) Frausto Hernández, José Angel; Lopéz Soriano, Eduardo Manuel; puemcuervo, emipsanchez; Villarreal M., María Guadalupe; Escuela de Ingeniería y Ciencias; Campus Monterrey; Elizondo Gracia, Ileana
    En los ambientes de manufactura donde la demanda supera substancialmente la capacidad de producción de la empresa se requiere de un procedimiento que sea consistente en el criterio de asignación de trabajos, en este caso la maximización de la utilidad final. Los modelos temáticos edificados son similares a los del método de Transporte y Asignación de Trabajos que tradicionalmente aparecen en la literatura, pero requieren de extensiones a los algoritmos ya que no todas las máquinas pueden manufacturar todas las órdenes. La primera etapa del proyecto desarrolla un heurístico que asigna tantas órdenes de manufactura a las máquinas como sea posible dentro de las restricciones de tiempo de cada máquina asegurándose que toda orden de producción asignada se elabora completamente en una máquina en particular evitando problemas de productividad y/o calidad si se fraccionara la orden en varias máquinas. La segunda etapa genera otro heurístico que aprovecha el remanente de tiempo de las máquinas para producir parcialmente el resto de las órdenes que quedaron pendientes hasta completar el período de tiempo en cuestión. Las órdenes no contempladas se difieren para un ciclo de producción posterior. Los heurísticos se desarrollan para empresas que no cuentan con software comercial puedan realizar su asignación de trabajos en forma estratégica utilizando Excel. Ambos, son extensiones de procedimientos ya existentes dentro del área de Flujo en Redes. El heurístico de la Fase I provee una solución aproximada como cota inferior a la solución óptima mientras que el segundo heurístico siempre converge a la solución óptima.

    Optimizing Route Planning in Diverse Landscapes: Integrating SLAM and RRT in Autonomous Drone Deployment.
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-06-11) Colín García, Daniel; Izquierdo Reyes, Javier; emimmayorquin; González Hernández, Hugo Gustavo; Molina Espinosa, José Martín; School of Engineering and Sciences; Campus Ciudad de México
    This thesis focuses on the implementation of improved route planning and terrain mapping in different types of structured landscapes by using advanced Simultaneous Localization and Mapping (SLAM) methods and Rapidly-exploring Random Tree (RRT*) algorithm in autonomous drone deployment, focusing on software development and simulation to improve tracking capabilities. This thesis is based on a single project that is a collaborative work of postgraduate students. The project aims to develop a drone-based telecommunications network that serves as a basis for exploration and monitoring in studied or designated areas. This research is based on the establishment of a system that integrates SLAM, which provides a quick and accurate map of complex environments. This is important for the correct drones' work and the best results. Meanwhile, the inclusion of an RRT algorithm enables us to raise the system's efficiency and accuracy in planning routes for drones as they navigate intricate urban and non-urban spaces. The project is exclusively based on software simulation, using tools like AirSim and Unreal Engine, which allow the creation of an environment to test how well different drones work, from a single area to specific coordinates, ignoring external conditions like weather and drone battery life. The use of these mapping techniques and this trajectory planning algorithm enables safe navigation and an understanding of the environment that allows drones to function properly to perform their tasks. The results obtained, and the methods applied in the thesis, hope to introduce efficiency and productivity in the planning of drone deployments in all structured environments. This path would open the way to new applications in areas beyond urban infrastructure.

    Fabrication, Characterization and Simulation of Organic Microencapsulated Phase Change Materials for Thermal Storage
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-06) Martínez Cervantes, Dannya; Otero Hernández, José Antonio; emimmayorquin; Chong Quero, Jesús Enrique; Hernández Cooper, Ernesto Manuel; Melo Máximo, Lizbeth; Bustamante, Rogelio; Escuela de Ingeniería y Ciencias; Campus Ciudad de México; Melo Máximo, Dulce Viridiana
    Phase change materials (PCMs) exhibit a physical phenomenon where a liquid-solid phase transition occurs in response to temperature changes. These materials have unique characteristics as they can release, store, and absorb energy under isothermal conditions or phase change process when it comes in contact with temperature rise or fall [3]. Currently, one of the application methods is through microencapsulation, known as core-shell. The major disadvantage of this type of system is the di↵usion of the material contained within the core shell and its spherical morphology. Therefore, this work focuses on the fabrication of a microen- capsulated system where the thickness of the outer layer and the amount of material contained can be controlled. Given the importance of using organic materials due to their environmental impact and low cost, the main components of this system are alginate and coconut oil. The method selected for encapsulation promotes the formation of spherical structures that allow for better thermal absorption distribution. The key to this was the development of a coaxial piece where, through a pump system, the volumetric flow of coconut oil and alginate was controlled. The diameters of the piece allowed for control over the size of the microen- capsulation. The results indicate the formation of PCM formed by a layer of alginate and a coconut oil core. Among the results, it is observed that the initial values of the mixture play an important role, as they can either separate or form a compound of alginate with oil. Finally, through a sensor system that records temperature changes at inter- vals, it is observed how the change in the presence of the microencapsulation is attributed to its energy absorption capacity over a thermal cycle.

    Earthquake response in mega cities: A mathematical model for the selection of relief shelters in the Valley of Mexico and a qualitative assessment for Istanbul, Turkey
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-06) Huerta De Rubín, José Gerardo; Mora Vargas, Jaime; emimmayorquin; Akhavan-Tabatabaei, Raha; Santos Borbolla, Cipriano Arturo; González Mendoza, Miguel; Escuela de Ingeniería y Ciencias; Campus Ciudad de México; Serrato García, Marco Antonio
    Natural disasters represent challenging situations globally, with earthquakes being some of the most devastating type of disasters. The difficulties to cope with them arise in contexts like mega cities, large urban agglomerations where the population dynamics make seismic disaster more struggling. In this sense, the use of humanitarian logistics techniques is an effective way to provide solutions in these contexts. In this thesis, a mathematical model is developed and used to support the selection of relief shelters from a set of potential locations. The model aims to minimize both the distances between the affected areas and the chosen shelter locations, as well as the costs of adapting the selected locations into relief shelters. The model was applied to different instances, from a small controlled one to understand and validate the way the model works, to scenarios with dimensions similar to (and even larger than) mega cities. The application of the model considered both real information gathered from a mega city in a seismic region (the Metropolitan Area of the Valley of Mexico; formed by Mexico City and several municipalities in the surrounding States of Mexico and Hidalgo), and simulated data based on the real one to face the difficulties to obtain all the required real data. Once the results were obtained for every model, a graphical tool was used to visualize them. That tool is ©QGIS, an open source Geographic Information System that allows to create maps using the resulting data from the application of the models. This visualization of results permits to identify if the results seem practical and reasonable, and represent a powerful tool to sustain the decision making after an earthquake. Finally, this work also contains a qualitative assessment of the circumstances of a different mega city with seismic danger: Istanbul, focused on a brief summary of the Istanbul Seismic Risk Mitigation and Emergency Preparedness Project (ISMEP); a document related to the way of coping with earthquakes in a different mega city located in a very seismic region.

    Proposal of a methodology for Engineering Design focused on mechatronic products for application in Mexico.
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-04) Salazar Calderón, Luis Ángel; Izquierdo Reyes, Javier; emimmayorquin; Navarro Tuch, Sergio Alberto; Icaza Longoria, Inés Álvarez; Escuela de Ciencias e Ingeniería; Campus Ciudad de México
    In the face of the technological era we live in, there is a huge demand for products that improve everyday activities, from automating large-scale processes within the industry to using smart devices in people’s daily lives. Therefore, mechatronics is a privileged area for the development of such products. Due to the complexity and level of specialization required by some mechatronic systems, situations that threaten the health of these product developments may arise. Thus, having the context upon which the design of such a product will be executed can provide the design team with tools to avoid such situations. This thesis presents the development of a methodology for the engineering design process focused on mechatronic products, intended for use under Mexican conditions. The problem-solving process proposed by Hyman served as the basis, conducting a comparison with multiple methodologies focused on mechatronics as well as more traditional processes, evaluating their main qualities and the adaptation of the process itself to solve problems. The methodology was structured into three stages: Information, Conceptual Design, and Embodiment Design, aimed at adapting the steps to obtain information, generate proposals, evaluate and select a proposal, develop the proposal, and test the proposal to solve a problem. The proposed methodology was evaluated through a case study for the conceptual design of a robotic platform on the worksite, allowing for the automation of the construction of confined walls in vertical buildings in Mexico. This resulted in the mechanical and electronic development of two subsystems focused on brick transportation and another for lifting the block for subsequent placement on the wall.

    Effects of ionic and nano selenium in the biogas production yield of the anaerobic co-digestion of harvested microalgae and sewage sludge 
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-06) Hernández González, José Isaac; Cervantes Avilés, Pabel Antonio; emimmayorquin; Cervantes Avilés, Pabel Antonio; Cuevas Rodríguez, Germán; Valenzuela Reyes, Edgardo Iván; School of Engineering and Sciences; Campus Ciudad de México
    The aim of this work was to evaluate the most productive substrate ratio concentration of harvested microalgae (HM) and sewage sludge (SS) in the anaerobic co-digestion (AcoD), assessed through the biogas production yield, as well as find the most beneficial selenium (Se) form and concentration in the AcoD of the most productive HM/SS ratio concentration. Five reactors were filled with the following substrate ratio concentrations: 50HM/50SS, 30HM/70SS, 10HM/90SS, 70HM/30SS, and the control reactor (inoculum and distilled water). The AcoD of HM and SS was carried out in mesophilic conditions and biogas was measured through potential assays. Minimal decrease in COD was observed, but total solids (TS) decreased through the AcoD, giving as result the 70MA/30SS ratio concentration reactor with the most efficient features for biogas production yield. For the evaluation of effect of Se in the AcoD of HM and SS, ionic and nano Se was added to four reactors with 70HM/30SS ratio concentration. Two nano Se and two ionic Se concentrations were used: 0.05 mg/L and 0.5 mg/L. Results indicated that the reactor with low concentration (LC) nano Se and high concentration (HC) nano Se displayed a 4.8 % biogas production enhancement, the reactor with LC ionic Se was the highest biogas production enhancement with 43.9 %, and the reactor with HC ionic Se demonstrated a 39.5 % biogas production improvement. The higher results in biogas production yield enhancement in the reactors with ionic Se added are attributed to the retention of ionic Se in the biomass of the digestate and the provision of essential nutrients, facilitating the synthesis of key enzymes and coenzymes, the promotion of the activity of anaerobic microorganisms could be carried out. In comparison with the reactors with nano Se, where Se NPs were precipitated since the beginning of the AcoD and the effects of nano Se couldn´t be applied.

    Evaluation of tribological behavior and machining performance of green cutting fluids for sustainable manufacturing
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-01-01) Aguilar Rosas, Oscar Alejandro; Farfan Cabrera, Leonardo Israel; puelquio, emipsanchez; Reséndiz Calderón, César David; Pérez González, José; Shirai Matsumoto, Concepción Keiko; School of Engineering and Sciences; Campus Estado de México; Calderón Nájera, Juan de Dios
    Metalworking fluids (MWFs) are used in almost all manufacturing processes since they help us to dissipate the heat generated during machining, lubricate the contact interface between the tool and the workpiece, aid in evacuating the chips, and prevent corrosion between galvanic pairs, resulting in extended tool life and improved surface finish. The current MWF market is satisfied by semisynthetic emulsions, which contain between 10% to 50% mineral oil content, and between 10% to 25% of functional additives, including petroleum-based emulsifiers; this implies that current MWF emulsions have low biodegradability properties, are prone to bacterial contamination (which may lead to health-related problems such as skin irritation, lung damage, and even cancer), and represent substantial economic losses due to the complex post-processing before their disposal. To date, some solutions have been given to solve these problematic issues, the most popular is the replacement of the mineral base oil of the emulsions with vegetable oil. Nonetheless, one of the major drawbacks of using these vegetable oils is the sustainability because most of them are edible. Thus, one of the novelties of this research is to propose the use of a non-edible oil (Jatropha oil (JO) extracted from Jatropha Curcas L.) and Cactus Pear, which, although it is an edible base stock, is highly efficient at retaining water and requires almost no attention during its farming stage, as the bio-based stocks to produce MWFs. Another major research opportunity in the development of water-miscible MWF is the replacement of the emulsifier itself, which is also a petroleum-based compound and has rarely been replaced by a sustainable alternative. In particular, partially deacetylated and fibrillated chitin nanofibers (PDFC), which can be produced by recycling natural waste products of the fishing/food industry, have shown excellent Pickering stabilization at low concentrations. Therefore, this research will also focus on replacing the typical emulsifiers by a green option. This thesis will encompass two studies: 1); The evaluation of the tribological and machining performance of JO + PDFC MWF emulsions, and 2) the evaluation of the tribological and machining performance of cactus pear mucilage-based MWFs. In both cases, the tribological performance of the MWFs was obtained via pin-on-disk or four-ball testing, while the machining performance was determined by actual turning operations, evaluating cutting forces, cutting temperature, surface finish, and chip quality.

    Design and topology selection method for brushless motors in regenerative dampers
    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-12-01) Aguilar Zamorate, Irving Sixto; Galluzzi Aguilera, Renato; puemcuervo; Ibarra Moyers, Luis Miguel; School of Engineering and Sciences; Campus Ciudad de México; Bustamante Bello, Martín Rogelio
    The objective of this thesis is to demonstrate the hypothesis that a regenerative damper will be able to fulfill efficient comfort and road holding constraints for a vehicle suspension if a proper method to design the electric motor is implemented and a suitable machine topology is selected. Previous is justified on the problem that the state of art in regenerative dampers is not clear which brushless permanent magnet rotor topology is appropriate nor a unified method that covers all the processes to develop this motor for regenerative dampers exists. The unified method includes the geometry parametrization and winding design, cross-section optimization to maximize torque, losses/efficiency characterization, and field-oriented control using MATLAB and FEMM, an open-source finite element program to promote its availability. The process is applied for a surface-mounted and two interior permanent magnet rotor topologies named single magnet and V-shape. Additionally, an analytical model for the surface mounted is presented based on literature due to a stable flux distribution is present. Moreover, the present method can be extended to other fields which use these types of motors as electric vehicles. The most suitable machine configuration is the surface-mounted permanent magnet since the torque is the highest combined with a low torque ripple and low permanent magnet mass compared with the interior magnets. The motor is validated in an appropriately designed regenerative suspension intended for a C-class vehicle. Optimal suspension control is applied to evaluate vehicle dynamics under two optimal operational modes: comfort and road holding. The regenerative suspension fulfills the expected behavior, even when a force compensation term is included to account for inertia and viscous damping, friction. Moreover, the device is energy-self sufficient in both operating modes, but energy recovery decreases when inertia is considered.

    (Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-06-02) Hernández Maldonado, Ana Rebeca; Keshtkar, Sajjad; puemcuervo, emipsanchez; García Guendulain, Crescencio; Del Angel López, Deyanira; Díaz Martínez, Juan Gabino; School of Engineering and Sciences; Campus Monterrey; Gutiérrez Carmona, Irandi
    The following thesis introduces a conceptual design of a smart satellite module for space de bris removal missions. Technological advances applied includes a tether system for its release and retrieval, a tracking system for non-cooperative space debris, an independent attitude control device, and a release net mechanism. Through the combination of space tethers and autonomous control orientation devices, the design aims to increase the accuracy of capture mechanisms, reducing the fuel usage and risk of collisions. The design and control algorithms will be evaluated through computer simulations for their future application in a physical prototype.
