This tree accelerates the selection of cross-device technologies by taking into account known use cases of interaction. Five different communication technologies were tested (Real-time Multiplayer, Nearby Messages, PeerJS, iBeacon and Eddystone) by means of 13 proof of concept applications distributed between both operating systems (Android-iOS, iOS-iOS, Android-Android) and the design of 20 architecture diagrams of three types: sequence (connection to services and message sending), deployment and component. The decision tree was validated by mobile development experts resulting in a maximum reduction of up to 30 days of technology selection research. The effectiveness of the tree as a tool is 60%, its usefulness 80% and its ease of comprehension 90%, according to the results obtained from the experts. / Revisión por pares

Manifiesta que el proceso de entrega de una empresa de productos lácteos tiene retardos en el despacho de los pedidos y también se han identificado pérdidas en las ventas. Esto debido al deficiente proceso manual de facturación y control de salidas de los productos terminados. Además, el manejo de la información de los pedidos por parte de la fuerza de ventas muestra ineficiencia en el momento de la toma de éstos, cuando se sale en busca de nuevos clientes y pedidos. Para esto, en este proyecto se implementa una aplicación distribuida que consta de dos componentes que se ejecutarán en distintas plataformas, un componente del lado cliente que se ejecutará en dispositivos móviles y un componente del lado del servidor que brindará servicios distribuidos al componente cliente y que también podrá ser accedido mediante un navegador web para permitir la gestión de ventas. Esta aplicación se realizará siguiendo el estilo arquitectónico web cliente servidor. El componente servidor contendrá una aplicación web que permitirá la gestión de ventas desde un navegador web y una capa de servicios que permitirá el almacenamiento y recuperación de los datos de los pedidos por parte del cliente desde una base de datos centralizada. El componente cliente será una aplicación hibrida para poder ser utilizada como si se tratase de una aplicación nativa y para permitir lograr la independencia del sistema operativo de la aplicación en los dispositivos móviles que se desplieguen. Finalmente se llegó analizar los resultados de la implantación de esta aplicación. Se logró disminuir considerablemente los tiempos de facturación y de la captación en campo de la información de los clientes y de los pedidos, permitiendo un control más seguro que minimice el margen de error humano como la perdida de información, cálculos erróneos, extravío y gran almacenamiento de documentos. / Tesis

Mixed reality, or augmented reality, where the real and the virtual worlds are combined, has seen an increase in interest in recent years with the release of tools like Google ARCore and Apple ARkit. Edge computing, where the distributed computing resources are located near the end device at the edge of the network, is a paradigm that enables offloading of computing tasks with latency requirements to dedicated servers. This thesis studies how edge computing can be used to bring mixed reality capabilities to mobile end devices that lack native support for that. It presents a working prototype for delivering mixed reality, evaluates the different technologies in it in relation to stability, responsiveness and resource usage, and studies the requirements on the end and edge devices. The experimental evaluation revealed that transmission time is the most significant chunk of end-to-end latency for the developed application. Reducing that delay will have a significant impact on future deployments of such systems. The thesis also presents other bottlenecks and best practices found during the prototype’s development, and how to proceed from here.

In recent years, mobile devices have played a significant role in daily life. As a result, Mobile Applications have become very popular. An increasing number of people are using mobile applications to handle an increasing number of personal tasks, as well as for amusement. To date, there are thousands of mobile applications available for a variety of purposes. However, there are very few specifically designed for local church use. Mobile applications are potentially more convenient and easier to operate than normal website for parishioners. Designing and implementing a mobile application for Crest Community Church, in Riverside, based on Android Developer Tools (ADT) and Android Software Development Kit (Android SDK) is this project’s primary objective. The objective of this project is to provide a communications platform where members of Crest Community Church can share news, discuss coming church events, promote and enhance the connectivity of this worship community, and provide mobile access to information not available on their present systems. A distinct feature of this project allows for communication between mobile application and webserver by creating a HTTP URL Connection. As a result, church members can publish news and events in a discussion forum as well as a dialog with other church members in a near real time format. The Crest users can also indicate that posted prayer request has been prayed for. In addition, this new application displays general church information, and provides the address and driving direction for potential visitors. Church members can also check the church’s calendar of events, special meetings and information about the Passion Center for Children ministry. This project has the ability to store and track pertinent information about each user, the content of all discussions, and retains member’s key contact data. This project successfully implemented a church mobile application. It demonstrated that a tailored mobile application can enhance the sense of community via internet for this congregation. It feather shows that mobile applications can greatly assist churches in community with members as well as visitors. The application also expanded the internet footprint of Crest Community Church, and offers other churches an avenue to improve their connectivity for the future.

In a big organization there are many events organized every day. To know about the events, we typically need to check an events page, rely on flyers or on distributed pamphlets or through word of mouth. To register for an event a user now a days typically does this online which involves inputting user details. At the event, the user either signs a sheet of paper or enters credentials in a web page loaded on a tablet or other electronic device. Typically, this is a time-consuming process with many redundancies like entering user details every time the user wants to register for a new event and re-entering the details at the event. This project designs a system that eliminates these redundancies and improves event management.
