Systemic archetypes for value co-creation based on collaborative cores: Case study at a telecommunication company

Currently value creation is not an exclusive aspect of the company; the clients co-creator role has taken preponderance due to the contribution of co-creation models, which demonstrate its utility empirically but does not take into account value construction with a systemic approach. The present work proposes a co-creation model through systemic archetypes that allow the capture of value elements, which arise from the service use experiences. The register of attributes through software is used after the client́s expression of the attributes using a constructive dialogue for which a qualitative focus is adopted in order to find a socially constructed meaning, having as research central axis the interpretative phenomenological analysis. The results show that the methodology allows the value capture through the evaluative speech acts which belong to the language philosophy.

Method to determine optimal hardware platforms in Human Centered Computing based on non functional requirements analysis

Human Centered Computing is a novel paradigm to process context information of human beings environment in which computers are invisible to the subject, providing tools and services depending on the context of each individual. An increasing interest is growing regarding embedded computers since they offer advantages related to portability, dedicated tasks, invisibility, amongst others. However, a plenty of hardware platforms are in the market, so it is complicated to determine which the best for a particular need. Benchmarks make those tasks easier by performing measurements in hardware by running applications and performing comparisons. Nevertheless, they are thought to meet some quite particular kinds of applications. Moreover, if some benchmark applications have to be merged, i.e. voice or images processing, there are not schemes to correctly measure hardware platforms. On the other hand, requirements such as reliability and availability are not commonly assessed as a dependant set in hardware platforms. In this work, we propose a novel method to select hardware architectures for Human Centered Computing based on benchmarking, genetic algorithms, weighted sums and statistical distances in order to consider non-functional requirements.

Motivation and Virtual Education in Computer Science: Case Universidad de Medellín-Colombia

Virtual education raises to students and teachers important challenges, normally different to those faced in conventional education. In the context of virtual education, a question that remains to be solved is associated with the level of motivation possessed by the students during the course. Usually, at the School of Engineering in the University of Medellín, this issue is tackled through activities such as chats and forums. Mostly, these activities are not enough to motivate the student in the activities related with the learning process. This work proposes two motivation strategies based on gamification and constructivism. These strategies are validated in a course called programming fundamentals, taught to all bachelor degrees given in the School of Engineering. Results obtained through the experiments suggest that proposed strategies improve the students performance and satisfaction in the course. Therefore, when teaching at the virtual scenario, using Information and Communication Technologies in the educational environment is not only the way to contact the student, it is the mean to develop pedagogical-didactic approaches that finally enrich the educational process and consequently motivate the student to perform well.

A novel application of System on Chip platforms over industrial sensor networks: A case of Ubiquitous Computing within a power generation plant

Ubiquitous Computing (UC) is a paradigm in which stakeholders interact with machines in a natural way, without constraints of time, place or access medium. Data is available everywhere to be read, consulted and modified if needed. Thus, UC becomes a powerful tool for industrial applications, where a plenty of sensors, actuators and controllers are integrated in order to produce outcomes efficiently. Nevertheless, it is common to find a lot of communication schemes that use proprietary protocols, so it is difficult to connect those different devices. Furthermore, some Information Systems inside companies are not able to transmit data outside their own networks into Internet. This work aims to show a study case where UC device is designed and implemented in a power generation plant, sensing level of combustible tanks. A System on Chip platform is used to provide flexibility, usability, better performance, better energy management and integration capabilities.

Meanful experiences for training in innovation of systems engineers: Case University of Medellín

The achievement of innovative results in academic spaces needs the constant search of the creativity. This implies defying the methodologies of traditional classes by means of utilization of special tools and techniques that suppose an additional effort for the teachers with regard to the strategies used per years. Make real the fantasy of the innovation is not a task easy to undertake in the academic occupation. This article describes some key to go beyond as for the use of techniques that improve the creativity to the interior of classes and presents results that demonstrate his potential in the generation of products with high degree of innovation. It presents in addition results of the implementation of creative techniques like design thinking, six hats and SCAMPER.

Ubiq-Ideas Machin: Ubiquitous computing system to support creative ideas generation sessions in open innovation

Ideas emerge in the less imagined scenarios, and it is mandatory to have a set of tools which ease their incorporation without time/place/access medium constraints, in order to maximize opportunities and avoid losing worthy contributions that become in incomes for innovations processes in companies or any other institution interested in actively involving their customers, employees, providers and other stakeholders in the Value Chain by means of co-creation. In this work we propose Ubiq-Ideas Machine, a ubiquitous computing prototype to support creative sessions of ideas generation by using a distributed scheme. This tool was built by reviewing literature and a strong field work with ubiquitous computing experts. We present the process until proposing the design and prototype generation. After a first assessment, an interesting projection is revealed due to a high commercialization impact.
