An Ambient Intelligence responds to user requests based on several contexts. A relevant context is related to what has happened in the ambient; therefore, it focuses a primordial interest on events. These involve information about time, space, or people, which is significant for modeling the context. In this paper, we propose an event-driven approach for context representation based on an ontological model. This approach is extendable and adaptable for academic domains. Moreover, the ontological model to be proposed is used in reasoning and enrichment processes with the context event information. Our event-driven approach considers five contexts as a modular perspective in the model: Person, temporal (time), physical space (location), network (resources to acquire data from the ambient), and academic events. We carried out an evaluation process for the approach based on an ontological model focused on (a) the extensibility and adaptability of use case scenarios for events in an academic environment, (b) the level of reasoning by using competence questions related to events, (c) and the consistency and coherence in the proposed model. The evaluation process shows promising results for our event-driven approach for context representation based on the ontological model.

Environmental Events

An Intelligent environment can respond to the necessities of the users according to the context, this is so that the individuals can have the ideal climatic conditions in order to go about their activities, these conditions are related through a series of special norms. The events that we describe in this paper are in relation to the events of the environment (temperature, humidity, brightness, and presence), also involved are different variables like time, space, or person, such are important in order to be able to model what is occurring in a determined place. In this project, we propose a personalized ontological design for the academic dominion. The ontological model is utilized for the identification of environmental events according to the data acquired from the environment through the simulation of intellectual agents. Also, our ontological model is used to rationalize with the information obtained from the identified events. The model of ontologies based on events considers four contextual questions like a perspective modular: person, seasonality (weather), spatiality (location), network (resources in order to acquire environmental data) and event (academic events). And the detector is based on rules obtained from the standards of optimum climatic conditions of a physical space.

Immersive Environment

The article is devoted to the scientific problem of theoretical elaboration and contextualization of immersive environment realized in the physical space of a gallery or museum, in VR and on the new virtual platforms on the Internet, as well as in hybrid space, in the augmented and mixed reality of the 21st century. The aim of the research is to identify the peculiarities of the formation of the immersive environment and of the practices of VR and AR projects creation in Ukrainian contemporary art in recent years. The task is to elaborate the theoretical bases of the development of immersive environments and VR, review and analysis of projects that use the digital technologies in order to create an immersion and AR. The methodology of the study consists in theoretical and field research of immersivity and in the author’s experiments development. The main method is a comprehensive and systematic approach to the development of the theory of virtuality, visual and photometric methods, analysis of concepts, spatial structure and technological features of online VR platforms and artistic realizations. The concept of sensorium is involved, which describes the feeling, perception and interpretation of information about the world around. The peculiarities of creating immersive environments in physical space in the projects «MetaPhysical Time-Space», «Refraction of Reality», «Living Energy» were explored (to be included into the national art discourse), as well as in VR in the frame of VR-festivals, such, as Carbon Media Art Festival, «Frontier» and «Virtuality» that serve as a testing ground for the development of new technological art. The possibilities of new online VR platforms, such as Mozilla Hubs, WebXR, AltspaceVR, artspaces.kunstmatrix, Cryptovoxels, Transmadatac Virtual Museum, are analyzed. The practice of creating VR projects on platforms on the Internet: Artefact Chornobyl 33 and Artefact Chornobyl + MADATAC, «VR Collider» and «Genesis» are considered as case study. Drift from immersive environments in physical space to virtual reality has been detected. The multi-vector nature of AR projects and different types of connection with book publishing, public art objects, contemporary sculpture and urban practice have been revealed.

New technologies have challenged the established conceptual understanding of time and physical space as we know it and problematized how cultural values and power dynamics between men and women are viewed. This study sought to examine the time–space distanciation and comprehension in the face of increased access to and use of new communication technologies by families in Kenya. The article addresses the following questions: (1) How have new media technologies in Kenya affected individuals’ use of space at the family level? (2) How do women and men navigate through changes in spaces occasioned by the new media technologies? (3) What influence have new media technologies had on gendered power dynamics between men and women in the family set up? A qualitative study was carried out between October 2018 and October 2019 in Uasin Gishu County in Kenya. Interviews and observation techniques were employed with a total of 42 purposively sampled participants taking part. Qualitative techniques were used to analyse the data. The study generated a number of findings that formed the basis of key recommendations thereof.

Representation model of composition event is a very important issue in the study of composition event. Aiming to solve the problem of no well reflecting the spatial-temporal characteristic of CPS (Cyber-Physical Systems) in current composition even models, a representation model of composition event based on multi-tuple is proposed for CPS in this paper. The contribution of the paper lies that we use five tuples: object, time, space, event and property, to represent a composition event of CPS, which not only can more comprehensively reflect the spatial-temporal characteristic of CPS event, but also can reflect the some dynamic change features of external environment. The simulation results show that our proposed scheme has several advantages in reducing event average error rate compared with some general event model methods.

Feeling united with academic community reflects in increased responsibility for one’s own quality of work. This is the quality of carrying yearly BASEES Conferences in Cambridge that impresses participants coming from the academic environments in which procedure and scope of events are not really respected. Therefore, learning from this kind of experience is always useful. The most inspiring thing is hope that conferences of such a level someday will become a routine for Ukrainian scholars as well. The more so, because our post-Socialist experience is interesting in itself for our foreign colleagues, since the way which the scientific rationality makes under conditions of overcoming totalitarian repression and aiming at democratic freedom is currently important not for Ukrainians only. Under current conditions, the part of rationality in the dimension of freedom obtains a universal meaning, making the need of reconsidering the phenomena of freedom even more rapid. This article is intended to present to Ukrainian academic community some theoretical and organizational achievements of this year’s BASEES Conference and to engage Ukrainian scholars more actively to participate in international academic events and considering the ways of implementing the experience received into their activities home. This year the conference was dedicated to the fifty years of the Prague Spring. The experience of the Prague Spring in the reflections of the BASEES conference proves the relevance of the issues of freedom and the need to rethink the key concept of modern thinking – progress. The critique of progress that puts under the question the significance of the concept itself for contemporary socio-philosophical discourse is, in the main, directed against progressism as a modern mechanistic version of progress. The revealing of the complex and ambiguous forms of progress in contemporary epoch tends to accept rather than reject the progress.

Introduction. The prevailing education model in Honduras is a teacher-centered one, where the main thrusts are the teacher and the lesson plans. This, along with the slow evaluation process and little improvement of the curriculum design of degrees in the healthcare sector poses a challenge in the enactment of new education methods. This article documents an expert panel which was comprised of deans from the different Medical Schools of the country where Continuing Medical Education (CME) and its educational methodologies were discussed. Presentation of experience. The Asociación de Educación Médica Hondureña carried out an expert panel through an updated approach of CME to discuss Medical Education (ME) methodologies widely used internationally: problem-based learning, reflective practice, formative assessment and self-regulated learning. Discussion. The knowledge gap between new methodologies and traditional ones in ME represents a challenge that CME can address through the use of effective pedagogical approaches in the development and execution of these types of activities. Conclusion. The use of updated methodologies in ME not only improves student training during undergraduate and postgraduate studies, but its CME. ME in Honduras is limited by economic factors, training, physical space and its acceptance by teachers and students. A sustained and systematic effort is necessary by all parties involved in teaching.

In the Collaborative Virtual Environments (CVE), there is a conflict between maintaining the state consistency and supporting more users sharing the virtual environment. A self-adaptive message filtering algorithm based on consistency QoS is proposed to improve both the consistency and scalability. Each user in the virtual environment has active workspace, influence area and dormancy zone according to the different requirement of consistency QoS. Time-space bounding sphere is defined to predict user’s active workspace to provide high consistency QoS. When two users’ time-space bounding spheres overlap, the key updates of two users are sent to each other in time to keep the state consistency. A self-adaptive threshold function model is used when two users’ influence areas overlap, which makes a tradeoff between consistency and scalability and provides a medium consistency QoS. Heart-beat packets are sent when two users’ dormancy zones overlap to filter messages in order to reduce the system traffic since the low consistency QoS is required. The results of traffic test and consistency QoS test in the experiment show that our algorithm can maintain the state consistency and reduce the consumption of network resources simultaneously.

Preface The curricular project of Technology in Electricity and Electrical Engineering by cycles of the Universidad Distrital Francisco José de Caldas (Colombia) celebrates every two years its international conference. Unlike previous editions, during 2021 the Universidad Distrital has its facilities closed, and with restricted access, as a preventive measure to avoid the spread of the SARS-CoV-2 virus. Probably in two years, for CITIE 2023, the conference will return to its usual physical space in Aduanilla de Paiba, our flagship library. However, for this fourth version of CITIE, we opted for a distance event, organized entirely by videoconference, an experiment that, although not a feature mastered by our community, was a success. The fourth International Conference on Technology and Electrical Engineering (CITIE 2021) was held on November 11-12, 2021. This event was attended by researchers from the electrical area with papers mainly focused on electronic instrumentation, control, power systems, and electromagnetic compatibility. From the talks and presentations, it was evident that our research community remains active and produces cutting-edge research despite the conditions of restriction and social unrest typical of our political and socio-economic circumstances, strongly affected by the COVID-19 pandemic. A total of 11 papers were submitted to CITIE 2021, of which 10 were approved by the jurors (conference committee members and international reviewers) in a double-blind evaluation process. The conference was held entirely online over two days, which included the test session, three 50-minute keynote speeches, and three author presentation sessions. The research papers were separated into three thematic sessions, Instrumentation and Control, Power Systems, and Electronic Compatibility. These papers were each given 20 minutes of presentation time, including five minutes for questions. The entire conference was broadcast live on the event’s YouTube channel, registering an average of 600 daily visits. I would like to take this opportunity to acknowledge the hard work of the entire CITIE 2021 committee. Their advice and support were fundamental to preparing for the conference. I would also like to thank the students of the Electrical Technology program who supported the videoconference platform and the live transmission. Likewise, a special thanks to the speakers and authors for considering CITIE 2021 as a means of dissemination of their researchers, and to the invited researchers, whose talks and discussions allowed to leave on the carpet countless ideas for further discussion and development of impact research. The three previous versions of CITIE allowed the development of activities such as business shows, workshops, and a degree of interaction that was not achieved in CITIE 2021. The face-to-face conferences allow a level of direct communication with authors and researchers that is difficult to replicate on a distance platform. Even so, CITIE continues to maintain its spirit of dissemination of research and innovation, as well as its function of identifying and promoting areas of research in the field of electrical energy. We are confident that this version of the event has provided a great experience for all attendees, increased interest in the research fields discussed, as well as renewed expectations for the CITIE 2023 meeting.

Neutron spin-echo spectrometers with a position-sensitive detector and operating with extended time-of-flight-tagged wavelength frames are able to collect a comprehensive set of data covering a large range of wavevector and Fourier time space with only a few instrumental settings in a quasi-continuous way. Extracting all the information contained in the raw data and mapping them to a suitable physical space in the most efficient way is a challenge. This article reports algorithms employed in dedicated software, DrSpine (data reduction for spin echo), that achieves this goal and yields reliable representations of the intermediate scattering function S(Q, t) independent of the selected `binning'.

Best Fit

A procedure is described for interpolating surface features on a map based on a two-dimensional time-space configuration of points. Initially an objective procedure is used to give a best fit of a previously obtained time-space configuration of points to the physical configuration of the same points. The resultant set of vectors, each of which shows the residual displacement between a point in time space and physical space, is used as the basis of a fast, objective procedure for interpolating any other points or lines in the time space. This enables such things to be shown as the time-space distortion of an urban street network or of a square graticule from physical space. The process can also be reversed so that, for example, the solution points of a facility location problem solved in time space can be converted to their equivalent locations in physical space.
