Measurement and dephasing of a flux qubit due to heat currents
2013
We study a flux qubit, made of a superconducting loop interrupted by three Josephson junctions, which is subject to a temperature gradient. We show that the heat current induced by the temperature gradient, being sensitive to the superconducting phase differences at the junctions, depends significantly on the state of the qubit. We furthermore investigate the impact of the heat current on the coherence properties of the qubit state. We have found that even small temperature gradients can lead to dephasing times of the order of microseconds for the Delft-qubit design.
Concentric transmon qubit featuring fast tunability and an anisotropic magnetic dipole moment
2015
We present a planar qubit design based on a superconducting circuit that we call concentric transmon. While employing a straightforward fabrication process using Al evaporation and lift-off lithography, we observe qubit lifetimes and coherence times in the order of 10us. We systematically characterize loss channels such as incoherent dielectric loss, Purcell decay and radiative losses. The implementation of a gradiometric SQUID loop allows for a fast tuning of the qubit transition frequency and therefore for full tomographic control of the quantum circuit. Due to the large loop size, the presented qubit architecture features a strongly increased magnetic dipole moment as compared to convent…
Conspicuous Consumption in Emerging Markets: The Case of Starbucks in Colombia as a Global and Sustainable Brand.
2021
Conspicuous consumption symbolizes ostentatious and material consumption through the purchase of products and services with a higher economic value and that allows their consumers to excel socially. However, conspicuous consumption often does not represent social and environmental values, because their products are often not characterized by being made through sustainable processes. United Nations, through its sustainable development agenda, invited companies to be aware of the social and environmental problems of the world and to be able to generate strategies that can be sustainable over time and allow the growth of both the company and society in general. This study analyses the case of …
ICT and tourism impacts in islands
2018
New technologies can represent, for some aspects, both a problem and a precious resource. As we concerns, in tourism sector, ICT can help in managing and promoting destinations in a better way than in the past, especially in those cases where problems linked with the management of tourist flows and the need to manage a sustainable development exists. Monitoring tourism impact at the destination is a fundamental issue in order to respect the right pressure and to avoid negative effects in the destination and with the residents. There are several devices available and useful for different needs, therefore almost each kind of monitoring and analysis can be supported by the right tools. This kn…
Robotics and automation for societal good : global South challenges and technology-policy considerations
2018
Robotics and automation and artificial intelligence technologies hold immense potential in addressing many of the societal challenges as exemplified in the sustainable development goals of the 2030 agenda of the United Nations. They have the potential not only to increase the standard of living in developed countries, but to improve the quality of life in the so-called «Global South». This article discusses underlying challenges and technology-policy considerations when deploying emerging technologies in developing and developed economies. Various examples and implementations in collaboration with humanitarians, researchers and developers, and professional organizations across the globe are…
The ICT Implication on CSR in the Tourism of Emerging Markets
2012
Abstract Tourism has a significant environmental, social and human impact. No other sector provides jobs and ensures wealth across poor countries in the same way as tourism. In the context of sustainable responsible tourism, the concept of Corporate Social Responsibility CSR has gained increased importance: CSR is a company's understanding of the role it plays in society, the environment in which it operates, the values it upholds and its awareness of the intended and unintended consequences of its actions. ICT can create many environmental benefits and there have been several optimistic assessments of the overall relationship between e-business and sustainable development. ICT-based servic…
Is There a Predisposition towards the Use of New Technologies within the Traffic Field of Emerging Countries? The Case of the Dominican Republic
2021
Technological devices are becoming more and more integrated in the management and control of traffic in big cities. The population perceives the benefits provided by these systems, and, therefore, citizens usually have a favorable opinion of them. However, emerging countries, which have fewer available infrastructures, could present a certain lack of trust. The objective of this work is to detect the level of knowledge and predisposition towards the use of new technologies in the transportation field of the Dominican Republic. For this study, the National Survey on Mobility was administered to a sample of Dominican citizens, proportional to the ONE census and to sex, age and province. The k…
Implementation of TICs for the Virtual Learning of Literary Subjects: From Aula Virtual to OCW and Universia
2016
Within the current European Convergence Process and the development of the new University degrees, a compromise has been reached to adapt the English Studies (before English Philology) curricula to the current needs of students in a highly competitive society. The final goal is to transform our education system into one of learning. This actually implies that the student must engage himself more closely with the university and that he may lead his coursework in a more autonomous way, backed up by more active educational strategies, such as the personalised tutoring guide, the use of the new technologies, and the team work.
'Where Have I Heard It?' Assessing the Recall of Traffic Safety Campaigns in the Dominican Republic
2021
Although traffic crashes are the eighth leading cause of death in the world, and are linked to vehicle and infrastructure-related factors, crash-related fatality rates are much higher in lowincome countries. Particularly, the Dominican Republic is the country with the highest accident rate in the whole American continent. Therefore, in the past few years, public agencies have been developing different measures aimed at reducing traffic fatalities, including road safety campaigns. The aim of the present study was to assess the recalling of such campaigns among the Dominican population, which may serve as an additional indicator to evaluate their effectiveness in this and other countries of t…
Sea Wave Energy. A Review of the Current Technologies and Perspectives
2021
The proposal of new technologies capable of producing electrical energy from renewable sources has driven research into seas and oceans. Research finds this field very promising in the future of renewable energies, especially in areas where there are specific climatic and morphological characteristics to exploit large amounts of energy from the sea. In general, this kind of energy is referred to as six energy resources: waves, tidal range, tidal current, ocean current, ocean thermal energy conversion, and saline gradient. This review has the aim to list several wave-energy converter power plants and to analyze their years of operation. In this way, a focus is created to understand how many …
