A Latent Class Analysis of Spanish Travelers’ Mobile Internet Usage in Travel Planning and Execution
2014
A study of 476 Spanish travelers found mixed interest and use for the many travel-related mobile internet services that are involved in planning and executing a trip. The findings indicate that these Spanish respondents can be classified into four segments based on the timing of using mobile apps for over a dozen activities involved in travel planning and execution: Savvies, Planners, Opportunists, and Low-techs. Each segment exhibits distinct patterns of mobile internet services usage. Savvies tend to be heavy mobile device users both before and during their trip, while Planners make heavy use of mobile devices in advance of but not during their trip. The Opportunists show a pattern oppos…
Location-Aware Mobile Intrusion Detection with Enhanced Privacy in a 5G Context
2010
Published version of an article from the journal: Wireless Personal Communications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11277-010-0069-6 The paper proposes a location-aware mobile Intrusion Prevention System (mIPS) architecture with enhanced privacy that is integrated in Managed Security Service (MSS). The solution is envisaged in a future fifth generation telecommunications (5G) context with increased but varying bandwidth, a virtualised execution environment and infrastructure that allows threads, processes, virtual machines and storage to be migrated to cloud computing services on demand, to dynamically scale performance and save power. 5G mob…
Wireless communication based on Raspberry pi and Codesys for mobile robots using IoT technology
2021
The industrial environment is going through exponential changes, due to the diversity of technological solutions that appear more and more frequently and the increase of productivity at increasing capacities. Due to this fact in the industrial area the number of devices, processing systems, collaborative robots, mobile robots and industrial equipment is increasing more and more. Consequently, there is a need for communication and connectivity of entities, common physical or virtual functioning and decision making, all of which are fundamental to the transition to the new concept of Industry 4.0. This study presents how wireless communication can be achieved in a mobile robotic platform that…
Social Media's Impact on Healthcare Services
2015
Abstract Taking into account the changes in recent years (the increased access to internet, the existence of affordable mobile devices and the ease of communication due to the growth of social media) it seems natural to investigate social media's impact on healthcare services. Furthermore, studies conducted worldwide show their benefits, both in terms of the patient, as well as the healthcare providers’. However, Romania's healthcare system faces serious problems on basic aspects. Thus, using secondary data, this paper aims to present the existing concerns about the impact of social media on healthcare services and to discuss to what extent they are applicable also in Romania.
A combined single range and single image device for low-cost measurement of building facade features
2008
The dimensions of building facades and window apertures are usually determined by making direct measurements using tapes and plummets. This approach, however, has a number of drawbacks including the physical risk to which the persons making the measurements are exposed. This paper proposes an indirect approach based on close range photogrammetry that is inexpensive, simple, fast and safe, and which does not require specialist staff or direct ground control measurements. The method is based on taking a picture using a digital camera and measuring the distance to the object using a handheld laser distance meter. Both items of equipment are mounted on a specially designed support that allows t…
Progressive Web Apps for the Unified Development of Mobile Applications
2018
Progressive Web Apps (PWAs) allow for web applications to be developed in an offline-first approach. While Web apps traditionally did not properly function without an Internet connection, PWAs enable them to be downloaded, installed and used offline on various systems, including mobile devices and personal computers. We present an introduction to the state-of-art in research and practice. Based on this, we discuss various underlying concepts and technologies. Then, we scrutinize and compare PWAs against cross-platform app development approaches on both technical and overarching aspects. A list of suggestions for future research is also presented. We urge academia to keep up with the latest …
Developing Mobile Ontologies; Who, Why, Where, and How?
2007
The number of mobile subscribers in the world is soon reaching the three billion mark. According to the newest estimates, majority of the subscribers are already in the developing countries, whereas the number of subscribers in the industrialized countries is about to stagnate around one billion. Because especially in the developing countries the only access to Internet are mobile devices, developing high quality services based on them grows in importance. Ontologies are an important ingredient towards more complicated mobile services. In this paper we refine the taxonomy for mobile ontologies and discuss their creation, business models, maintenance and intellectual property rights (IPR).
A cross-sectional study on smartphone uses among pregnant women attending childbirth classes in the Metropolitan Area of Palermo, Italy: The Stop-Pho…
2022
Background: Prevalence of mobile device addiction has increased over the years; both women and men have assimilated the mobile phone as a central component of their personal existence: integrating it into their lifestyle or becoming so dependent on it that life without it has become unimaginable. Smartphones generate radio-frequency electromagnetic fields. While short-term exposure in adults was considered quite safe, effects of long-term exposure or exposure during pregnancy on fetuses or during breastfeeding on newborns are not well studied yet. The objective of the present study was to investigate the prevalence and usage characteristics of smartphones among a sample of pregnant women, a…
On-line quizzes to evaluate comprehension and integration skills
2016
[EN] This work demonstrates the use of a 2.0 tool, namely, Socrative, to evaluate one of the cross-curricular competences indicated by the Universitat Politècnica de València, specifically, comprehension and integration. It has been applied to the courses in different areas: sciences, engineering and languages. As part of its implementation, activities were proposed that could be done at the beginning, during or at the end of the class to, on the one hand, help students acquire the knowledge associated with the course(s), and on the other, gather evidence that demonstrates acquisition of said competence. The results show a high level of satisfaction by the students with the use of the Socra…
Multi-objective optimization for computation offloading in mobile-edge computing
2017
Mobile-edge cloud computing is a new cloud platform to provide pervasive and agile computation augmenting services for mobile devices (MDs) at anytime and anywhere by endowing ubiquitous radio access networks with computing capabilities. Although offloading computations to the cloud can reduce energy consumption at the MDs, it may also incur a larger execution delay. Usually the MDs have to pay cloud resource they used. In this paper, we utilize queuing theory to bring a thorough study on the energy consumption, execution delay and price cost of offloading process in a mobile-edge cloud system. Specifically, both wireless transmission and computing capabilities are explicitly and jointly co…
