      Luna, Renato Mercado; Soto, Gabriel Benavente; Oliden, Daniel Subauste; Padilla, Alfredo Barrientos (2021-01-01)
      Nowadays, due to climate change and many other facts affecting daily life a trend to use eco-friendly transportation ways has arisen, and from them the one mostly used and with the highest acceptance is biking. Therefore, several companies have emerged offering bike-sharing systems, and those systems have been greatly accepted in the different metropolises around the world. The generalization of these systems has created a new need: to manage them efficiently. Consequently, in this work, we propose a software architecture and the implementation of a bike-sharing management system using the Internet of things (IoT).

      Atencio, Luis; Aybar, Bruno; Barrientos Padilla, Alfredo; u201313101@upc.ecu.pe (Association for Computing Machinery, 2018)
      The present research aims to compare the different technologies that allow real-time communication between Android and iOS devices. We conducted a measurement-driven experiment to test the performance of each technology under different scenarios. We determine their functionality according to the environment for which they have been developed, showing competent information about their capabilities based on the communication channel they use, and their performance measured in milliseconds. The final results allow mobile application developers to determine which technologies suits them the best, based on the specific context of their projects.

      Chioino, Jamil; Contreras, Ivan; Barrientos, Alfredo; Vives, Luis; u201211429@upc.edu.pe; u201210351@upc.edu.pe; pcsiabar@upc.edu.pe; luis.vives@upc.pe (Association for Computing Machinery, 2018-04-09)
      This analysis proposes a decision tree for selecting cross-device communication technologies for iOS and Android mobile devices. 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.
    • Implementation of a Fashion Virtual Assistant with the Use of a Kinect v2 Camera and Image Processing

      Vizcarra, Christopher; Medina, Gabriel; Barrientos, Alfredo (2021-01-01)
      This article is about the problem and development of a fashion virtual assistant proposed by using a Kinect v2 camera and image processing, for fashion retail stores. It comes up mainly as a response to the inability of providing unique experiences during the shopping process through the use of diverse devices. Because of this, similar virtual assistant solutions, oriented to provide clothing recommendations, were analyzed to be able to provide software that could give a more personalized suggestion for the users based on their physical characteristics.

    • PMMA-Assisted Plasma Patterning of Graphene

      Bobadilla, Alfredo D.; Ocola, Leonidas E.; Sumant, Anirudha V.; Kaminski, Michael; Seminario, Jorge M.; alfdoug@gmx.com (Hindawi Limited, 2018)
      Microelectronic fabrication of Si typically involves high-temperature or high-energy processes. For instance, wafer fabrication, transistor fabrication, and silicidation are all above 500°C. Contrary to that tradition, we believe low-energy processes constitute a better alternative to enable the industrial application of single-molecule devices based on 2D materials. The present work addresses the postsynthesis processing of graphene at unconventional low temperature, low energy, and low pressure in the poly methyl-methacrylate- (PMMA-) assisted transfer of graphene to oxide wafer, in the electron-beam lithography with PMMA, and in the plasma patterning of graphene with a PMMA ribbon mask. During the exposure to the oxygen plasma, unprotected areas of graphene are converted to graphene oxide. The exposure time required to produce the ribbon patterns on graphene is 2 minutes. We produce graphene ribbon patterns with ∼50 nm width and integrate them into solid state and liquid gated transistor devices.

    • A sentiment analysis software framework for the support of business information architecture in the tourist sector

      Murga, Javier; Zapata, Gianpierre; Chavez, Heyul; Raymundo, Carlos; Rivera, Luis; Domínguez, Francisco; Moguerza, Javier M.; Álvarez, José María (Springer Science and Business Media Deutschland GmbH, 2020-01-01)
      In recent years, the increased use of digital tools within the Peruvian tourism industry has created a corresponding increase in revenues. However, both factors have caused increased competition in the sector that in turn puts pressure on small and medium enterprises’ (SME) revenues and profitability. This study aims to apply neural network based sentiment analysis on social networks to generate a new information search channel that provides a global understanding of user trends and preferences in the tourism sector. A working data-analysis framework will be developed and integrated with tools from the cloud to allow a visual assessment of high probability outcomes based on historical data, to help SMEs estimate the number of tourists arriving and places they want to visit, so that they can generate desirable travel packages in advance, reduce logistics costs, increase sales, and ultimately improve both quality and precision of customer service.

    • Serious Game for the Virtual Practice of the Emplantillado in the Constructive System of adobe with reinforced cane

      George, Centeno; Carlos, Egusquiza; David, Mauricio; Peruvian University of Applied Sciences, Lima, Perú; Peruvian University of Applied Sciences, Lima, Perú; Peruvian University of Applied Sciences, Lima, Perú (Association for Computing Machinery, 2017-12-20)
      At present, the training of university students and the specialization of professionals are accompanied by a series of educational tools based on digital environments and applications for specific areas in education; In this process of application of the technology exists a methodology called Serious Game oriented towards some specific areas like Simulation in subjects of building and construction; Since this field is new in higher education, there are not many specific applications, such as the case of emplantillado for simulation of constructions using adobes reinforced with cane. The objective of this study is to demonstrate that the Serious game methodology, oriented to the teaching the course of the Preliminary Works of the Faculty of Architecture, can improve students learning and optimize their skills for the emplantillado in construction systems using the application for iPad. The application has been tested in a group of twelve students who were part of the experimental group in relation to the execution time, attempts made and qualification obtained; In contrast to evaluate the time to solve the test for emplantillado into de groups that performed the same exercise; an ANCOVA was used to evaluate the main effects and interactions to answer the null hypothesis. This ANCOVA model for balanced cases of type III includes a covariate that is correlated with the dependent variable and means on the dependent variables adjusted due the to the effect the covariate had on it.

      Laporte, Claude Y.; O’Connor, Rory V.; García Paucar, Luis Hernán; Luis.garcia@upc.edu.pe (Springer International Publishing, 2016-03)
      This paper outlines the details of seven case studies involving the pilot usage of the new standard ISO/IEC 29110standard ‘Lifecycle Profiles for Very Small Entities’, which was specifically designed by Working Group 24 of ISO/IEC JTC1/SC7 to address the standardization needs of Very Small Entities (VSEs). The purpose of this paper is to add substantially to the body of knowledge and the literature on the rollout and implementation of this new and evolving standard and to act as guidance for other researchers in the design and implementation of ISO/IEC 29110 case studies. Furthermore it is hoped that that the lessons learnt from these case studies will help promote the adoption of this new standard in an industrial setting.
