<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>The latest advances in computational power of small portable devices enables the development of new forms of Augmented Realities, namely Augmented Reality Shared Spaces. In this work, we will explore this technolo- gy to improve the collaborative work between people in the same physical space allowing them to share and visualise virtual contents. The idea is to have a 3D scene shared between several people where everyone can see and interact with and explore its use in psychotherapy context. These live interactions can also be used to improve the quality of collaborative work by presenting in real time ideas and thoughts of any participant directly on top of the 3D model. In the case of a psychotherapy session typically patients describe their feelings and fears to the therapist. This may be centred on virtual representations of their phobic elements, supporting interactions with them, being those actions and re- sults observable by both in their shared space. Our main goal is to apply and evaluate this concept, specially in exposure-based therapies, where it is im- portant for the therapist to control and manipulate the scene that the patient is exposed to in order to obtain the desired emotional activations.</span></p></div></div></div>

Shared Space

The aim of paper is a presentation an idea of shared space in the cities and results of implementation of this solution in the cities of Poland. The methodology of elaboration consisted of carrying out a review of the literature, comparing existing solutions and formulating conclusions regarding implementation. This trend, which has appeared over the past 50 years as a counterbalance to the pedestrianization of public spaces, is at the beginning of the 21st century experiencing its second youth and is being implemented in many areas in intensive urban development, especially in urban centers and areas of historic character. Shared space solutions are an integral way of shaping functions and forms of revitalized public spaces. These solutions contributes to improving the quality of public space and traffic safety, revitalizing social life, improving and reducing the environmental nuisance caused by traffic and finally created liveable city. Analyzes effectuated indicate, that in central areas of cities in Poland whose spatial arrangement is legally protected, the forms of shared spaces solutions are strongly influenced by strong conservation restrictions in these areas. This means the need  to respect existing historical conditions in shaping public spaces, as well as limited transformation possibilities. The Polish solutions of shared spaces presented in this paper of in their forms and quality do not differ from the standard functional solutions abroad. Solutions implemented in the Polish conditions, however, are more modest in terms of materials and implemented in a smaller number than is the case in Western European countries.

New Criterion

The article proposes a new criterion for lighting quality that extends the existing UGR. The proposed criterion is tested in an experiment on real lighting installations - Moscow metro stations. At metro stations, the spatial-angular distribution of luminance is measured using a camera that shoots in RAW format and a luminance meter. A luminance meter is used to normalize the image to absolute luminance values. In the experiment, observers evaluate the quality of station lighting and compare the results with the calculation of a new criterion. A high correlation of the results obtained by observers and calculated using the new quality criterion is shown. For a few stations, a 3D model is built, and the criterion is calculated according to the model. The article concludes that the quality criterion is applicable to the assessment of lighting quality. Moreover, the proposed criterion can be considered an extension of the existing UGR.

Contemporary Situation

The contemporary architectural production in the Alps of Piedmont has to be studied taking into consideration the contrasting phenomena of depopulation and tourism that have involved the mountain areas of the region during last century. In the fifties and sixties the percentage of abandonment of the high valleys reaches even 80-90%. Entire communities move to industrial urban centers in the cities on the plain. On the other side we witness to a strong polarization of the winter stations that become real “banlieues blanches” for the free time of the citizens and where the architecture of alpine modernism, with various forms, shapes. The paradox nowadays is that the rarefaction of abandoned and depopulated territories is necessary to force to start and choose new innovative paths. We witness a contemporary situation with different shades: on one side the well-established touristic territories that need projects to promote the redevelopment and diversification, on the other side the marginal places where are rising new visions are practices of reactivation of the territory in which architecture is fundamental. The topic of quality of the construction of the physical space intersects with the regeneration of places on a cultural basis, new agriculture and green economy, innovative development of the patrimony, sustainable tourism, with inclusive and participative paths of nature, by giving new meanings to places and building new economies and identities.

Improvement Strategies

The education based on simulation is an educationalstrategy where students learn from their errors, developing skills, knowledge, competences,etc. in a controlled environment. During the process of teaching by simulation, it is necessaryto execute various types of assessments (diagnostic, summative, formative) in order tomake adjustments or changes in the educational process of the students, therefore identifying areas of opportunity for improvement. With the simulation, different processes can be taught, like interprofessionalism and collaborative work. Nowadays, there is a major concern for added safety and the quality of care for the patients and their families. Therefore, a WHO study group determined the basic interprofessional competences, and has been given the task of disseminating and promoting interprofessional education. Some educational institutions in the US, Canada and Europe have integrated interprofessional and collaborative work in simulation practices. All the activity by simulation must be evaluated in order to provide feedback to the participants and establish improvement strategies. The assessment of the interprofessional work focuses on the evaluation of common skills and competencies among various health professionals.

In this paper we describe eBird, a citizen-science project that takes advantage of the human observational capacity to identify birds to species, which is then used to accurately represent patterns of bird occurrences across broad spatial and temporal extents. eBird employs artificial intelligence techniques such as machine learning to improve data quality by taking advantage of the synergies between human computation and mechanical computation. We call this a Human-Computer Learning Network, whose core is an active learning feedback loop between humans and machines that dramatically improves the quality of both, and thereby continually improves the effectiveness of the network as a whole. In this paper we explore how Human-Computer Learning Networks can leverage the contributions of a broad recruitment of human observers and processes their contributed data with Artificial Intelligence algorithms leading to a computational power that far exceeds the sum of the individual parts.

A computer-generated hologram (CGH) allows synthetizing view of 3D scene of real or virtual objects. Additionally, CGH with wide-angle view offers the possibility of having a 3D experience for large objects. An important feature to consider in the calculation of CGHs is occlusion between surfaces because it provides correct perception of encoded 3D scenes. Although there is a vast family of occlusion culling algorithms, none of these, at the best of our knowledge, consider occlusion when calculating CGHs with wide-angle view. For that reason, in this work we propose an occlusion culling algorithm for wide-angle CGHs that uses the Fourier-type phase added stereogram (PAS). It is shown that segmentation properties of the PAS can be used for setting efficient conditions for occlusion culling of hidden areas. The method is efficient because it enables processing of dense cloud of points. The investigated case has 24 million of point sources. Moreover, quality of the occluded wide-angle CGHs is tested by two propagation methods. The first propagation technique quantifies quality of point reproduction of calculated CGH, while the second method enables the quality assessment of the occlusion culling operation over an object of complex shape. Finally, the applicability of proposed occlusion PAS algorithm is tested by synthetizing wide-angle CGHs that are numerically and optically reconstructed.

AbstractSmartphone-based imaging devices (SIDs) have shown to be versatile and have a wide range of biomedical applications. With the increasing demand for high-quality medical services, technological interventions such as portable devices that can be used in remote and resource-less conditions and have an impact on quantity and quality of care. Additionally, smartphone-based devices have shown their application in the field of teleimaging, food technology, education, etc. Depending on the application and imaging capability required, the optical arrangement of the SID varies which enables them to be used in multiple setups like bright-field, fluorescence, dark-field, and multiple arrays with certain changes in their optics and illumination. This comprehensive review discusses the numerous applications and development of SIDs towards histopathological examination, detection of bacteria and viruses, food technology, and routine diagnosis. Smartphone-based devices are complemented with deep learning methods to further increase the efficiency of the devices.

The Impact

The COVID-19 pandemic that has hit the world in the year 2020 has put a strain on our ability to cope with events and revolutionized our daily habits. On 9 March, Italy was forced to lockdown to prevent the spread of the infection, with measures including the mandatory closure of schools and nonessential activities, travel restrictions, and the obligation to spend entire weeks in the same physical space. The aim of this study was to assess the impact of the COVID-19 pandemic and lockdown measures on quality of life (QoL) in a large Italian sample, in order to investigate possible differences in QoL levels related to both demographic and pandemic-specific variables. A total of 2251 Italian adults (1665 women, mainly young and middle adults) were recruited via a snowball sampling strategy. Participants were requested to answer to an online survey, which included demographic and COVID-related information items, and the World Health Organization Quality of Life BREF questionnaire (WHOQOL-BREF). The results showed statistically significant differences in QoL depending on a number of variables, including sex, area of residence in Italy, and being diagnosed with a medical/psychiatric condition. To our knowledge, this is the first study to assess QoL during COVID-19 pandemic in Italy, therefore the present findings can offer guidelines regarding which social groups are more vulnerable of a decline in QoL and would benefit of psychological interventions.

Small Models

Deep neural network (DNN) has shown significant improvement in learning and generalizing different machine learning tasks over the years. But it comes with an expense of heavy computational power and memory requirements. We can see that machine learning applications are even running in portable devices like mobiles and embedded systems nowadays, which generally have limited resources regarding computational power and memory and thus can only run small machine learning models. However, smaller networks usually do not perform very well. In this paper, we have implemented a simple ensemble learning based knowledge distillation network to improve the accuracy of such small models. Our experimental results prove that the performance enhancement of smaller models can be achieved through distilling knowledge from a combination of small models rather than using a cumbersome model for the knowledge transfer. Besides, the ensemble knowledge distillation network is simpler, time-efficient, and easy to implement.
