Augmented Reality is a technology that complements the perception and interaction with the real world and allows the user to be in an enhanced environment with additional information generated by the computer. In recent years the development of this technology in the educational field has taken a big rise. This article presents the development of scenarios for the conservation of natural sites through the Augmented Reality. For this purpose, a set of slides and a mobile application have been developed that allow elementary students to know about the importance and conservation of the natural sites of the province of Chiriquí, in the Republic of Panama. The evaluation of the resulting products was carried out third grade students, obtaining excellent results. © 2017 AISTI.

The volatile compounds of four peach cultivars (Prunus persica L.) were studied: Sudanell, San Lorenzo, Miraflores and Calanda (two clones, Calante and Jesca). 17-23 Samples of each cultivar with the same maturity level were analyzed, measuring color, firmness, and soluble solids content. The pulp was crushed and mixed with water prior to HS-SPME analysis, and GC-MS was used to determine the volatile compounds. Sixty-five compounds were identified using spectral library matching, Kovat's indices and, when available, pure standards. The main components were lactones and C6 compounds. From the distribution of these compounds, Principal Component Analysis led to the clustering of the samples according to their different cultivars. Finally, Canonical Component Analysis was used to create a classification function that identifies the origin of an unknown sample from its volatile composition. The results obtained will help to avoid fraud and protect the European Designation of Origin 'Melocotón de Calanda'. © 2012 Elsevier Ltd. All rights reserved.

Discrete Event Dynamic Systems: Theory and Applications | Year: 2012

Minimal siphons in the class of S4PR nets have become a conceptual and practical central tool for the study of the resource allocation related aspects in discrete event dynamic systems as, for example, the existence of deadlocks. Therefore the availability of efficient algorithms to compute the minimal siphons is essential. In this paper we try to take advantage of the particular properties of the siphons in S4PR to obtain an efficient algorithm. These properties allow us to express minimal siphons as the union of pruned minimal siphons containing only one resource. The pruning operation is built from the binary pruning relation defined on the set of minimal siphons containing only one resource. This pruning relation is represented bymeans of a directed graph. The computation of the minimal siphons is based on the maximal strongly connected components of this graph. The algorithm is highly economic in memory in all intermediate steps when compared to the classical algorithms. © Springer Science+Business Media, LLC 2012.

A polarization independent reconfigurable optical demultiplexer with low crosstalk between adjacent channels and high number of potential allocated channels is designed on silicon on insulator technology. On to off state transitions can be implemented by changing the coupling factor or the ring length. Wavelength selective switch units are cascaded to form the demultiplexer. Crosstalks below -30dB with 50GHz channel spacing and losses below 1.5dB in the off state are obtained from simulations. Designs using carrier dispersion effect and power consumption estimations are included. © 2014 Optical Society of America.

Expert Systems with Applications | Year: 2011

During the last years the use of Web Service-based applications has notably increased. However, the security has not evolved proportionally, which makes these applications vulnerable and objective of attacks. One of the most common attacks requiring novel solutions is the denial of service attack (DoS), caused for the modifications introduced in the XML of the SOAP messages. The specifications of existing security standards do not focus on this type of attack. This article presents the S-MAS architecture as a novel adaptive approach for dealing with DoS attacks in Web Service environments, which represents an alternative to the existing centralized solutions. S-MAS proposes a distributed hierarchical multi-agent architecture that implements a classification mechanism in two phases. The main benefits of the approach are the distributed capabilities of the multi-agent systems and the self-adaption ability to the changes that occur in the patterns of attack. A prototype of the architecture was developed and the results obtained are presented in this study. © 2010 Elsevier Ltd. All rights reserved.

This manuscript presents a mobile monitoring application to allow a patient to monitor a chronic disease using mobile devices. This application is developed according to three components that enable the semi-automatic development of software, independent of the target disease and adaptable to the particular user needs. First, we present ontologies that classify medical elements such as diseases, recommendations, preventions, foods, mobile devices and diet suggestions. The second element is the distribution of the devices in layers, allowing the generation of final applications distributed in a medical context. These layers are defined to develop and maintain the set of applications. The third and most important element is developing patterns known as MobiPatterns. A MobiPattern defines the schema of each control module that is a part of the final application. These elements include formal models that seek to uncover fundamental principles and essential features and algorithms, which need to be revisited in the context provided by mobility. Aspects of the application such as the functionality, user interface, and response time for a group of patients have been evaluated in a final application targeting patients with diabetes. The design focuses on simplicity, extensibility, scalability, heterogeneity, and application customization. © 2013 Elsevier B.V. All rights reserved.

This study provides an overview of the development of hard and soft skills from project-based curriculum planning, and suggests ways to evaluate them in the context of engineering education and their importance in the training of future engineers. The research described here is descriptive and analytical, involving a detailed study to determine the skills generated by the end of the semester. Data collection was performed by applying a questionnaire of closed assertions with five levels of response, consisting of 24 items based on the proficiencies established in the CDIO Syllabus to geology course students. From the results obtained, it seems that students have high expectations in relation to the competencies generated, and it became evident that students have a good level of intellectual capital, but they have poor non-technical skills. The main student perceptions regarding the impact of the course were associated with the ability to obtain a positive outcome the end of the course, and the need to gain the theoretical background knowledge of a basic science course as the common core in engineering. © WIETE 2014

Engineers without borders is based on education for development, in order to form a global professional with the capacity for action, committed and knowledgeable about the issues and challenges of a globalised world. This study is supported by Edgar Dale's Pyramid of Learning and provides an overview of the development of skills from the project-based curriculum planning, constructed on a ludic and motivational approach to teaching geology to third-year civil engineering students. The purpose of this active methodology was to encourage students to acquire both soft and hard skills, which were evaluated through practices conducted in the field by theoretical and technical activities. From the results obtained, it can be interpreted that students had good expectations and felt fully motivated with respect to the skills achieved. Similarly, it was evident that students have good intellectual capital, but with weak non-technical skills. © 2016 WIETE.

The virial theorem for nonrelativistic complex fields in D spatial dimensions and with arbitrary many-body potential is derived, using path-integral methods and scaling arguments recently developed to analyze quantum anomalies in low-dimensional systems. The potential appearance of a Jacobian J due to a change of variables in the path-integral expression for the partition function of the system is pointed out, although in order to make contact with the literature most of the analysis deals with the J = 1 case. The virial theorem is recast into a form that displays the effect of microscopic scales on the thermodynamics of the system. From the point of view of this paper the case usually considered, J = 1, is not natural, and the generalization to the case J ≠ 1 is briefly presented. © 2015 Chris L. Lin and Carlos R. Ordóñez.

This paper has the objective to provide a scientific applied exhibition for a new modeling concept in fire sciences in an important case of study that has no important advances since a lot time. Is the concept of the energy transformation in a electrical wire from electrical power to radiant heat. We will give a general glimpse of the state of the art in electrical design, focusing on the fire safety, where there are defined two general types of fire hazards, the electrical arcing that has been widely studied, and the thermal generation where we focus our research. This work uses a new mathematical model to perform calculations of thermal conduction and heating caused by electrical current in electrical conductors with overload condition. This new model is approximately one thousand times more accurate than the classical Joulés Law. © 2003-2012 IEEE.
