Treballs Finals de Grau d'Enginyeria Química, Facultat de Química, Universitat de Barcelona, Curs: 2021-2022, Tutor: Carles Fité Piquer, Cooling tower is a unit operation widely used in the chemistry industry. It is used to cool water that has lost its utility as a refrigerant because it has been used in condensers and heat exchangers. After cooling, water can be reused or send back to the environment without thermal damage. Although cooling towers can generate large steam plumes, which causes many people to associate this steam with smoke and pollution, it is a clean operation that takes advantage of the principle of cooling by water evaporation. In this project, a tool is created to facilitate the design for this type of operation. That is why an executable application has been made, using the python programming language. The program calculates the height of a counterflow water cooling tower for a given set of parameters: water and air inlet conditions, water outlet conditions and individual transfer coefficients. The solution is obtained by solving the mass and heat balances and differential transfer equations through the gas and liquid film along the cooling tower. This tool is though for a user that can be specialized or not in cooling towers, in order that the user can get design parameters easily and quickly

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2021, Director: Oliver Díaz i Jairo Luzón, [en] This project shows the design and development of an architecture based on Docker technology with the aim of studying its performance through metrics and being able to generate the visualization of the data in real time to extract possible conclusions. To test the tool, data on the global incidence of COVID-19 have been used. The architecture consists of different parts that configure it and for its implementation the most current and innovative tools have been used. For the data collection layer, a Kafka bus has been used in streaming based on an API (Application Programming Interface) of data, for data storage MongoDB has been used as a database, for data processing and its subsequent Visualization of the metrics, Prometheus has been used together with Grafana, allowing a User Friendly visualization through graphs, and finally, for the visualization of the data, MongoDB Charts has been used, a tool that has allowed the visualization of the data through heat maps. It can be concluded that the architecture has been designed in such a way that it is capable of managing data from any type of data source in a generic and fully modular and scalable way.

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2017, Director: Sergio Sayago Barrantes, [en] The development of software for the iOS platform have become in recent years an important part of the software development sector. The speed at which the complexity of the software to be developed has grown, has made the architecture models used to date obsolete to meet the needs of a long-term development. In this paper, the existing architecture models for the development of iOS applications will be studied and documented. After that, software design patterns will be used to design and document an architecture proposal with which to try to ensure the sustainability of an iOS software project. Finally, the proposed architecture model will be applied in a software development by way of example, giving rise to an application for iOS, trying to guarantee the understanding of this work, and contribute all my analysis with the proposal model, to the paradigm of application development for iOS.

En un dels projectes més recents de la meva pràctica professional, l'arquitectura del programari conjuntament amb l'estructura dels equips de desenvolupament donen lloc a certs problemes de desenvolupament i gestió que dificulten el seu manteniment. L'arquitectura actual del projecte que ha servit d'inspiració per a aquest treball final de carrera és la d'una aplicació clàssica JavaEE, amb capes de presentació, seguretat, negoci i persistència, on els majors obstacles per a la seva explotació i manteniment són la mida de l'aplicació, la gran quantitat de mòduls que conformen l'aplicació i les seves interdependències, que imposen limitacions i condicionants. Aquest treball final de carrera consisteix en la implementació d'una aplicació fent servir una arquitectura alternativa que permeti solucionar els principals problemes de l'arquitectura actual. En uno de los proyectos más recientes de mi práctica profesional, la arquitectura del software conjuntamente con la estructura de los equipos de desarrollo dan lugar a ciertos problemas de desarrollo y gestión que dificultan su mantenimiento. La arquitectura actual del proyecto que ha servido de inspiración para este trabajo final de carrera es la de una aplicación clásica JavaEE, con capas de presentación, seguridad, negocio y persistencia, donde los mayores obstáculos para su explotación y mantenimiento son el tamaño de la aplicación, la gran cantidad de módulos que conforman la aplicación y sus interdependencias, que imponen limitaciones y condicionantes. Este trabajo final de carrera consiste en la implementación de una aplicación usando una arquitectura alternativa que permita solucionar los principales problemas de la arquitectura actual. In one of the latest projects of my professional practice software architecture together with the structure of the development teams give rise to certain problems that hinder development and management maintenance. The current architecture of the project that has served as inspiration for this final is a classic application JavaEE, with layers of presentation, security, business and persistence, where the biggest obstacles for its operation and maintenance are size of the application, the large number of modules that make up the application and their interdependencies, constraints and limitations imposed. This final work consists in implementing an application using an alternative architecture that allows to solve the main problems of the current architecture.

In this paper, we present a software architecture and a development environment for the implementation of applications based on secure mobile agents. Recent breakthroughs in mobile agent security have unblocked this technology, but there is still one important issue to overcome: the complexity of programming applications using these security solutions. Our proposal aims to facilitate and speed up the process of implementing cryptographic protocols, and to allow the reuse of these protocols for the development of secure mobile agents. As a result, the proposed architecture and development environment promote the use of mobile agent technology for the implementation of secure distributed applications. © 2009 Elsevier Inc.
